Menstrual health interventions, schooling, and mental health problems among Ugandan students (MENISCUS): study protocol for a school-based cluster-randomised trial

Abstract

Background

Menstrual health is an increasingly recognised public health issue, defined as complete physical, mental, and social well-being in relation to the menstrual cycle. The MENISCUS trial aims to assess whether a multi-component intervention addressing physical and emotional aspects of menstrual health improves educational attainment, mental health problems, menstrual management, self-efficacy, and quality of life among girls in secondary school in Uganda.

Methods

The study is a parallel-arm cluster-randomised controlled trial with 60 schools (clusters) in Wakiso and Kalungu districts, with a mixed-methods process evaluation to assess intervention fidelity and acceptability and economic and policy analyses. The schools will be randomised 1:1 to immediate intervention or to optimised usual care with delayed intervention delivery. The intervention includes creation of a Menstrual Health Action Group at schools and NGO-led training of trainers on puberty education, development of a drama skit, delivery of a menstrual health kit including reusable pads and menstrual cups, access to pain management strategies including analgesics, and basic improvements to school water, sanitation, and hygiene facilities. Baseline data will be collected from secondary 2 students in 2022 (median age ~15.5 years), with endline after 1 year of intervention delivery (~3600 females and a random sample of ~900 males).

The primary outcomes assessed in girls are (i) examination performance based on the Mathematics, English, and Biology curriculum taught during the intervention delivery (independently assessed by the Uganda National Examinations Board) and (ii) mental health problems using the Total Difficulties Scale of the Strengths and Difficulties 25-item questionnaire. Secondary outcomes are menstrual knowledge and attitudes in girls and boys and, in girls only, menstrual practices, self-efficacy in managing menstruation, quality of life and happiness, prevalence of urogenital infections, school and class attendance using a self-completed menstrual daily diary, and confidence in maths and science.

Discussion

The trial is innovative in evaluating a multi-component school-based menstrual health intervention addressing both physical and emotional aspects of menstrual health and using a “training of trainers” model designed to be sustainable within schools. If found to be cost-effective and acceptable, the intervention will have the potential for national and regional scale-up.

Introduction

Background and rationale {6a}

Menstrual health (MH) is defined as complete physical, mental, and social well-being in relation to the menstrual cycle [1]. Poor MH is an increasingly recognised public health issue [2, 3], and improving MH is essential to meeting the Sustainable Development Goals for gender equality, good health, quality education, sustainable water and sanitation, and related human rights [4]. Challenges to achieving MH among girls include inadequate puberty education and knowledge, lack of social support from teachers and peers, and insufficient access to appropriate products and water, sanitation, and hygiene (WASH) infrastructure [5]. These psychosocial and physical challenges to menstrual health impact on girls’ ability to succeed and thrive mentally and physically within the school environment and beyond [6, 7]. Menstrual health may also impact on educational outcomes but few intervention studies have evaluated this [8]. Improving secondary education for girls can potentially lead to sustained, long-term benefits to education [8], health (mental, reproductive, sexual) [9], productivity [2], and the environment [10] through multiple pathways (e.g. earnings, standard of living, child marriage and early childbearing, health, nutrition, well-being, agency and decision-making, and social capital).

In Uganda, it is estimated that only 35% of women aged 15–49 have the physical and social environment needed to manage their menstruation [11]. The Ugandan Government has the political will to improve MH [12], for example by forming a National Menstrual Hygiene Management (MHM) Steering Committee, holding the first international MHM conference in 2014 and celebrating International MHM Day each year. In 2015, the Ugandan Ministry of Education and Sports (MoES) published a Circular on Provision of Menstrual Hygiene Management (MHM) facilities to all primary and secondary schools ((Circular No. 1/2015).1/2015). This Circular recommends provision of clean, private, toilet facilities; regular supply of water and soap; emergency supplies of pads and painkillers; training of teachers, health assistants, and inspectors; and involvement of parents in supporting and providing MH information and materials. However, a recent review found that although most schools (n = 98; 94%) received this Circular, only 23 (30%) acted upon it [13].

A recent systematic review [5] showed that MH research has focused largely on describing the extent of poor MH with relatively few randomised controlled trials (RCTs) evaluating interventions which address common antecedents of menstrual experience, including knowledge, social support, restrictive behavioural expectations and the physical environment. A mid-term review of the UNICEF/Columbia University’s “MHM in Ten” initiative to advance the MH agenda in schools by 2024 recently highlighted a need to understand how school-based MH interventions are delivered and scaled [14].

This paper describes the protocol for the MENISCUS trial, a school-based cluster-randomised trial evaluating the impact of a school-based MH intervention on the education, health, and well-being of secondary school girls in Uganda. The MENISCUS trial will address evidence gaps on MH intervention effectiveness [5], process evaluation [4], and policy guidance. The intervention, grounded in social cognitive theory, was designed and piloted following formative research in Wakiso District in 2016 which showed that poor MH is a key factor associated with girls missing secondary school and affects their well-being [15]. The formative research found (i) an unmet need for effective interventions to enable girls to better manage both the psychosocial (anxiety, stigma, and distress) and physical aspects (pain management, use of appropriate materials to prevent leakage of menstrual blood, WASH facilities) of menstruation; (ii) the importance of including boys and teachers in a school-based MH intervention; and (iii) that self-collection of vaginal swabs for testing for bacterial vaginosis and vaginal yeast was acceptable and feasible in this setting [16]. The intervention was piloted in two schools in Wakiso District in 2017–2018 and found to be feasible to deliver and highly acceptable to stakeholders. The findings further suggested that the MENISCUS intervention may improve girls’ education and health in the Wakiso District school context [17, 18]. The aim of the current trial is to rigorously evaluate the impact of the intervention on education, health, and well-being outcomes among girls in 60 secondary schools in Uganda.

A completed SPIRIT checklist is available as a supplement (Additional file 1).

Objectives {7}

We hypothesise that improved educational attainment, mental health outcomes, and related health- and well-being outcomes will be achieved by improving self-efficacy for MH in Ugandan secondary schools, through improving the MH social and physical environment, and supporting girl’s behavioural capability and observational learning.

The trial objectives are:

  1. 1.

    To evaluate whether the MENISCUS intervention improves educational attainment based on the Mathematics, English, and Biology curriculum taught during the intervention delivery and reduces mental health problems (primary outcomes) among secondary school girls in Uganda

  2. 2.

    To evaluate whether the MENISCUS intervention improves the following secondary outcomes:

  1. i)

    Knowledge of puberty and menstruation; attitudes towards menstruation (girls and boys)

  2. ii)

    Menstrual practices at the last menstrual period (LMP)

  3. iii)

    Knowledge and practice of pain management during LMP

  4. iv)

    Self-efficacy in addressing menstrual needs at LMP

  5. v)

    Quality of life and subjective well-being (happiness and life satisfaction)

  6. vi)

    Prevalence of urogenital infections (bacterial vaginosis, vaginal yeast, and urinary tract infections (UTI))

  7. vii)

    School and class absence during menses (in a random subsample of girls)

  8. viii)

    School and class absence overall (in a random subsample of girls)

  9. ix)

    Self-confidence in mathematics and in science abilities, respectively

  1. 3.

    To conduct a process evaluation to assess whether the intervention was implemented with fidelity, and to understand the contextual factors affecting the implementation, the acceptability to participants and the intervention mechanisms

  2. 4.

    To evaluate the costs of setting up and running the intervention package, the unit cost per female student reached and the incremental cost-effectiveness of the intervention per unit increase in selected policy-relevant outcomes, relative to optimised usual care

  3. 5.

    To assess the policy environment around menstrual health in Uganda, focusing on how implementing the intervention contributes to, and aligns with, the attainment of the Government policy objectives on MH management in schools

Trial design {8}

This is a parallel-arm, cluster-randomised control trial in 60 schools (clusters) with a 1:1 allocation ratio of clusters randomised to immediate delivery of the intervention or optimised usual care, with a mixed-methods process evaluation, and economic and policy analyses. Schools randomised to the optimised usual care arm will be offered the intervention at endline (approximately 1 year after randomisation).

Methods: participants, interventions, and outcomes

We used the SPIRIT reporting guidelines in writing this protocol paper [19].

Study setting {9}

The trial will be conducted in secondary schools in Wakiso and Kalungu districts in the Central region of Uganda. Wakiso District has a total area of 2704 km2 and includes both urban and rural areas. It partly encircles Kampala (Uganda’s capital city). According to the census in 2014, the population was estimated at 2 million, of whom 339,137 (17.3%) were aged 10–17 years and 48.9% of the 13–18-year-olds are estimated to attend secondary school [20]. Kalungu District is largely rural with an estimated population of 183,232 in 2014, of whom an estimated 40,960 (23%) were aged 10–17 years, with 36% of 13–18-year-olds attending secondary school [21].

Eligibility criteria {10}

Schools

Inclusion criteria for schools

Mixed-sex secondary schools with S1–S4 classes; day or mixed day/boarding schools; at least minimal WASH facilities (including an improved water source and sex-specific sanitation facilities that are functional, usable, and accessible to female students at the time of the rapid assessment eligibility survey) [22], estimated enrolment of approximately 50–125 female S1 students as of January 2020 (before COVID-19 lockdown) in Wakiso and 40–125 female students in S1 in Kalungu, based on the 2019 report on the Master List of Education Institutions in Uganda [23].

Exclusion criteria for schools

Schools that are currently participating in a menstrual health-related programme; boarding schools with no day students; single-sex schools and schools exclusively for students with disabilities.

Trial participants

Inclusion criteria for trial participants

(i) All female students in S2 in 2022 who are present at the time of the baseline survey, whose parent/guardian provided consent (if aged <18 years) and who have assented/consented to the trial and intervention procedures, and (ii) a simple random sample of 15 male students (in S2 in 2022) per school, present at the time of the baseline survey who have consented to the trial procedures. Furthermore, all female students present at the time of the endline survey in 2023 with consent/assent for the research will be eligible for the outcome assessment, as will the male students with baseline data.

Inclusion criteria for the nested sub-study

A simple random sample of 25 female students in each school will be randomly selected from those enrolled in the trial, to participate in a daily diary sub-study.

Who will take informed consent? {26a}

Informed consent procedures

Trained research team members will seek (i) written informed school-level consent from head teachers or directors to cover school-level research and intervention activities and (ii) written informed parent/guardian consent for female students obtained in person where possible, through information meetings held at each school. Parents/guardians who were unable to attend information meetings at school were reached through home follow-up visits or through phone calls to seek documented verbal informed consent. The consent forms include procedures for the self-collection of two vaginal swabs, one of which will be stored and will be shipped overseas, and for all anonymised data collected to be shared with other researchers. A separate consent form was administered for the menstrual cup provision, so parents/girls could opt to participate in all trial activities except for receiving a cup. The ethics committees agreed a waiver for parent/guardian consent for boys, as their participation in the (knowledge-focused) boys’ survey was deemed to carry minimal risk.

For student assent, information videos explaining trial procedures will be available for girls whose parent/guardian consent to the trial either including or excluding the menstrual cup, respectively. Male participants will be shown a video describing relevant procedures for boys. All three videos will be available in English and Luganda. Students will be asked by a trained research assistant to watch the relevant video on a tablet with headphones, they will also answer a few questions at the end of the video to assess their understanding of the trial and if they agree, they will provide secure electronic (e-) assent by signing on the tablet. Participants are given a paper copy of the assent form to retain.

Participants selected for qualitative interviews will be asked for parent/guardian consent and student assent prior to taking part in interviews (except for female students who already consented to the main trial that includes consent for qualitative interviews). Additional parent/guardian consent (for girls) and student assent (for all students) will occur prior to the endline survey for students who were not present at baseline.

Additional consent provisions for collection and use of participant data and biological specimens {26b}

Consent and assent were collected for collection and use of participant data and biological specimens (vaginal swabs and urine samples) as part of the main trial consent procedures.

Interventions

Explanation for the choice of comparators {6b}

The choice of comparator was chosen to align with Government MH guidelines and is optimised usual care. Optimised usual care will include (i) a copy of the Government Circular on Provision of MHM for primary and secondary schools ((Circular No. 1/2015).1/2015) [13], (ii) the 2018 National Sexuality Education Framework for each school [24] and (iii) copies of the Government Menstruation Management Reader to distribute to each girl and boy in S2. The Reader was written for girls and boys in primary schools to help them understand what menstruation is, why it happens, how to manage it and who to talk to about it. Schools randomised to the comparator arm will be able to receive the MENISCUS intervention after the endline survey.

Intervention description {11a}

The schools randomised to the intervention arm will receive the optimised usual care plus the MENISCUS intervention which includes puberty education, a drama skit, provision of a menstrual health kit and training, pain management, WASH improvements, and creation of a Menstrual Health Action Group (AG). Details of the MENISCUS intervention are given in Table 1, reported according to the TIDieR framework.

Table 1 MENISCUS intervention reported according to the TIDieR framework

The MENISCUS intervention is grounded in social cognitive theory which suggests that individuals learn by observing others [25]. The theory suggests that the following factors reinforce behaviour change: increased social support for and instilling expectations of behaviour change, increased self-efficacy, and using observational learning. During our formative work, we developed a logic model of change with stakeholders. Aligning this logic model with the core constructs of social cognitive theory, we developed a theoretical framework for the intervention which asserts that the intervention (i) increases girls’ self-efficacy to manage their menstruation (e.g. through provision of an MH kit and pain management options), (ii) positively reinforces girls’ learning (and also that of boys, teachers, and parents) to create a more supportive MH environment (e.g. through drama) and (iii) reinforces behaviour change through positive reinforcement and expectations (e.g. through improving WASH facilities and reduced teasing) [18].

Criteria for discontinuing or modifying allocated interventions {11b}

Adverse events (including serious adverse events) will be logged and reviewed by the trial clinical officer and the independent Data Monitoring and Ethics Committee if necessary, as described in the “Adverse event reporting and harms {22}” section. If these are deemed to be related to aspects of the intervention (most likely to analgesic use or the menstrual cup), the relevant intervention component (painkillers or cup) will be withdrawn from the participant.

Strategies to improve adherence to interventions protocols, and any procedures for monitoring adherence {11c}

Based on our pilot study, we anticipate high levels of uptake of most of the individual and behavioural components (drama skit, MH kit, and pain management); however, we saw lower adherence to delivery of puberty training by the teachers and the WASH component [17]. To improve overall school-level adherence (the WASH component, delivery of puberty education and drama skit), Menstrual Health Action Groups (MH AG) at each school will be tasked with ensuring that each element of the intervention is delivered, maintained, and sustained. The MH AGs will also engage schools to implement the training of trainers’ model which allows schools to deliver the trainings in a way that suits their school schedules. We will evaluate school-level adherence and individual-level exposure data as part of the process evaluation and in the endline survey. The implementing partner will record attendance at trainings and schools will also be asked to track and report their activities. This information will be triangulated with observations conducted as part of the process evaluation.

Interventions: concomitant care {11d}

The MENISCUS intervention will not require alteration to usual care pathways (including the use of any medication).

Provisions for post-trial care {30}

The trial sponsor carries Clinical Trial/Non-Negligent Harm Insurance and Medical Malpractice Insurance.

We do not expect serious adverse events due to our intervention, but in case of referrals due to SAE/SAR, we will make clinical care payments or reimburse the participants on the bills paid as stipulated in the private health facility signed Memorandum of Understanding. For suspected cases of toxic shock syndrome (TSS) due to the use of the menstrual cup, immediate referral for admission will be made to the designated district or national referral health facilities. We will pay for transfer to the hospital as needed for trial participants.

Outcomes {12}

The primary outcomes are educational attainment and mental health problems among girls present at endline, which is approximately 12 months after randomisation. Secondary outcomes are shown in Table 2.

Table 2 Primary and secondary impact outcome measures

Educational attainment will be assessed through bespoke pre-tested assessments administered and marked by the Uganda National Examination Examinations Board (UNEB). The baseline assessment will test Mathematics and Biology material taught to S1 students pre-intervention (2020–2021), and the endline assessment will assess recently taught Mathematics, Biology, and English material. UNEB assessors will be masked to the trial arm. The outcome will be the composite examination score at endline. The rationale for the subject choice is that the Biology curriculum taught in S2 includes puberty knowledge in the reproduction topic and is directly related to our intervention and that English and Mathematics are core subjects recognised by policymakers as influential for scale-up.

Mental health problems will be assessed for all girls at baseline and endline using the Total Difficulties Scale of the Strengths and Difficulties Questionnaire (SDQ-25). This includes emotional symptoms, attention, and peer-relationship problems. The outcome will be total SDQ-25 score, analysed as the examination data above. The SDQ-25 has been validated among adolescents in sub-Saharan Africa including in Uganda [27].

Participant timeline {13}

Different items will be measured according to the point in time when the data are collected. The enrollment into the study is over 3 months, and assessments for the primary and secondary outcomes will take place at different time points up to 12 months, with the majority of the assessments at both baseline and endline (Fig. 1).

Fig. 1

Time schedule of enrolment, interventions, and assessments

Sample size {14}

The sample size of 60 schools is based on an estimated harmonic mean of 60 female students per school at endline. This sample size provides 84% power to detect a standardised mean difference of 0.2 for continuous outcomes, assuming an intra-cluster correlation (ρ) of 0.05 and type 1 error of 0.05. The effect size of 0.2 is that observed for the primary outcome of SDQ score for girls in the pilot [17] and is considered moderate for educational outcomes and hence of policy relevance. This sample size provides 90% power to detect 12% vs 20% participants answering all knowledge questions correctly in the control vs intervention arms for girls (assuming ρ = 0.05) and 85% power to detect 4% vs 12% for boys (as in the pilot), assuming 10 boys per school are seen at endline. We have not adjusted the type 1 error because the two primary outcomes are independent, and an improvement in one without the other will be informative. From our pilot, we expect >95% of girls to be menstruating at endline, and this is accounted for in the power calculation where relevant.

The subsample of 1500 girls selected to provide daily diary data on school/class attendance and their menstrual cycle over 12 weeks (60 school days) at endline provides >98% power to detect a 20% reduction in period-related absence at endline based on pilot data [17] and ~89% power to detect this difference by district or other equally sized subgroups.

Recruitment {15}

Schools were selected and assessed for eligibility in two stages. First, an initial desk review was conducted using the 2019 Master List of Education Institutions. Of 631 secondary schools listed in the two districts (583 in Wakiso and 48 in Kalungu), 160 schools (138 in Wakiso, 22 in Kalungu) were deemed potentially eligible based on the listed information (i.e. mixed-sex, not exclusively boarding, and 40–125 (Kalungu) or 50–125 (Wakiso) female students registered in S1). The remaining schools were stratified by district and Government/private ownership and randomly ordered.

The second stage was a rapid assessment which consisted of stakeholder workshop, phone calls, school visits, and interviews to confirm eligibility and assess the schools’ physical and social environments for MH, in preparation for the trial. Of 110 head teachers of schools contacted, 84 were deemed potentially eligible for the trial from an initial screening phone call and 75 (89% of those potentially eligible) were invited to participate in the rapid assessment. Following the rapid assessment, 67 schools were confirmed eligible and 58 (87%) agreed to participate. Head teachers of these schools and district officials were invited to a second stakeholder workshop in each district in October 2021, where results of the rapid assessment were discussed and schools were asked to sign a Memorandum of Understanding (MOU) and provide a list of female students due to start S2 in 2022 if they agreed to participate in the trial. We assessed a further two schools (to replace two that declined to participate) from the original list for eligibility in February 2022 to achieve the final sample size of 60 trial schools (16 in Kalungu District and 44 in Wakiso District).

Assignment of interventions: allocation

Sequence generation {16a}

The 60 trial schools will be allocated using 1:1 restricted randomisation. Within each district, we will stratify schools by median baseline examination score (high/low) and will use covariate-constrained randomisation to minimise imbalance with respect to key factors (mean baseline examination score, past school examination scores, mean baseline SDQ score, school type (Government vs. private), mean score on the Menstrual Practice Needs Scale, and the number of S2 female students). A list of 1000 eligible allocations will be randomly selected from those meeting the specified balance criteria and will be sent to the data manager by the trial statistician.

Concealment mechanism {16b}

We will minimise biased recruitment by conducting the randomisation after the baseline survey [28] and conducting semi-public randomisation ceremonies to select the allocation.

Implementation {16c}

Semi-public randomisation ceremonies will be held in each district following completion of the baseline survey, in the presence of representatives from schools, the District Education Officer (DEO), the MoES, and the MoH. At these ceremonies, one allocation will be randomly selected from the list of 1000 allocations as follows: Three representatives will each select one ball from an opaque bag to form a 3-digit number corresponding to the selected allocation sequence. A fourth ball will be selected, to decide which schools are in the intervention arm (even digit) and which are in the control arm (odd digit).

Assignment of interventions: blinding

Who will be blinded {17a}

The primary outcome of the educational assessment will be masked as it will be independently administered by UNEB with no knowledge of arm allocation. We will minimise bias in other outcome assessments by having separate teams for implementation (WoMena Uganda) and outcome assessment (MRC/UVRI and LSHTM Uganda Research Unit). Masking of participants, school staff, and implementers is not possible as it will be clear whether the intervention is being implemented. Laboratory technicians testing self-collected swabs for bacterial vaginosis, vaginal yeast, and UTI will be masked. All outcome data will be anonymised, analysed, and interpreted masked to the trial arm. The clinical officer will not be masked to arm as they will be training staff in the intervention schools and will be responsible for assessing causality of adverse events.

Procedure for unblinding if needed {17b}

The independent Data Monitoring and Ethics Committee will advise if the principal investigator needs to be unblinded due to safety concerns.

Data collection and management

Plans for assessment and collection of outcomes {18a}

Prior to randomisation, the research team will be trained on collecting baseline survey data, which will be conducted in all the 60 schools before randomisation. This will include qualitative process evaluation baseline data. After randomisation, the intervention will be implemented by WoMena with ongoing process evaluation data collection. The endline survey will take place approximately 1 year after randomisation. Details of outcome measures and tools used are given in Table 2.

Plans to promote participant retention and complete follow-up {18b}

The trial is powered to compare outcomes between participants in the two randomised groups at endline, adjusting for school-level baseline measures of outcome variables. There may be differential loss-to-follow-up by arm, if, for example, the intervention reduces school dropout. We will collect data on school dropout in girls and adjust for the proportion dropout in endline analyses.

Data management {19}

Baseline and endline survey data will be self-collected by participants on tablets using ODK Collect software and uploaded to the MRC/UVRI and LSHTM Uganda Research Unit secure ODK Central server. Other quantitative data (daily diaries, laboratory forms, and analgesic vouchers) will be collected on paper case report forms (CRFs) and entered into a REDCap database. The data manager will regularly monitor data quality and any data queries will be resolved in collaboration with the relevant field team member or data entrant. In-depth interviews and focus group discussions will be audio-recorded and transcribed verbatim, including relevant non-verbal communications, and translated into English by the study interviewers for those conducted in Luganda. Cost data will be inputted into an Excel-based costing tool.

In the endline survey, female participants will be asked a set of additional questions on current genital symptoms. After completing the survey, trained study staff will explain and demonstrate the procedure for obtaining the vaginal swab. These will be tested for bacterial vaginosis and vaginal yeast. After the student has watched the video and asked any questions, the study staff will pass the student the 2 swabs for self-collection in a private setting. The swabs will be returned to the staff member. Participants reporting urogenital symptoms will be referred to an appropriate clinic for syndromic management and treatment as per Ugandan Clinical Guidelines. Those with symptoms of a UTI (e.g. urinary burning and frequency) will have their urine tested by Multistix 8 dipstick to look for signs (e.g. nitrite and leucocyte esterase positivity) to aid diagnosis of a UTI as per Ugandan Clinical Guidelines. The test result will be sent with the participant to the local clinic for management.

The process evaluation will use quantitative data from the endline survey supplemented with data from log books, structured observations, focus group discussions and in-depth interviews (Tables 3 and 4). This will enable us to understand how the intervention was implemented and received and the social, structural, and logistical factors that impede or facilitate this, as well as how staff and students were able to engage with it. We will also explore implementation processes and mechanisms of impact, and how these vary across the schools, using qualitative data. Data will be collected from all intervention schools via phone interviews with one senior staff member at baseline and endline and semi-structured interviews with one member of the school’s MH Action Group member purposively sampled to ensure overall variation across schools in gender and type of member (e.g. staff, student, other stakeholders) at mid-line and endline. More in-depth qualitative data will be collected from 4 purposively selected case study schools: group discussions with female students, male students and school staff at mid-line and endline and semi-structured interviews with staff and female students at mid-line and endline and with caregivers at endline.

Table 3 Overview of qualitative data collection activities
Table 4 Process evaluation research questions and data collection methods and sources

The economic evaluation will evaluate the costs of setting up and running the intervention package, the unit cost per female student reached, and the incremental cost-effectiveness of the intervention per unit increase in selected policy-relevant outcomes, relative to optimised usual care. The cost-effectiveness measures will be compared to similar school-based interventions in the region to inform scalability and financial sustainability. The policy analysis will assess the policy environment and financial sustainability of our intervention in line with Government policies and frameworks for MH and sexual and reproductive health.

Confidentiality {27}

Identifiable data collected will be stored securely and their confidentiality protected in accordance with the Data Protection Act 1998. The risk of disclosure will be minimised by training staff on the need for confidentiality (including training on Research Ethics), secure storage of documents, and use of linked data with a unique participant ID instead of names or other personal identifiers. All information regarding the participants will remain confidential to the extent allowed by law. Screening forms and case report forms will be kept in a secured location with access limited to authorised study staff. Consent and assent forms will be stored separately in a locked cabinet as will all other forms, logbooks, and appointment books that link participant ID numbers to other identifying information.

Plans for collection, laboratory evaluation, and storage of biological specimens {33}

The self-collected vaginal swabs will be transported to the MRC/UVRI laboratory in Entebbe for processing and storage. Upon receipt, one swab will be Gram stained and Nugent scored [29]. The second swab will be stored immediately in a cool box before being transferred to a −80C freezer within 24 h for storage and potential future testing related to vaginal microbiota. Participants with symptoms of a UTI (e.g. urinary burning and frequency) will have their urine tested by Multistix 8 dipstick to look for signs (e.g. nitrite and leucocyte esterase positivity) to aid diagnosis of a UTI as per Ugandan Clinical Guidelines. The test result will be sent with the participant to the local clinic for management.

Statistical methods

Statistical methods for primary and secondary outcomes {20a}

We will follow CONSORT guidelines for the analysis of cluster-randomised trials [30]. A Statistical Analysis Plan will be finalised prior to data unblinding and analysis. A participant flow diagram will be completed, following CONSORT guidelines for CRTs. Descriptive statistics for school-level and individual-level baseline characteristics will be shown by arm and will include mean and SD (or median and range if non-normal) (for continuous variables) and counts and proportions (for categorical variables). Factors showing substantial baseline imbalance by arm (agreed in advance of unmasking by the co-investigators) will be noted for inclusion in the effectiveness analysis. The primary and secondary outcome analyses (Table 2) will be carried out for all schools as randomised (intention-to-treat). Intervention effects will be estimated using individual-level regression analysis, adjusted for clustering by school and for baseline measures of outcome variables, restriction variables and factors imbalanced by arm at baseline. Results will be presented as standardised mean difference (continuous) or odds/prevalence ratio (binary) with a 95% confidence interval. For the analyses of daily diary data, there are repeated measures per girl, and analyses will additionally adjust for within-girl clustering using random-effects. Sensitivity analyses will be conducted, including randomisation inference.

Interim analyses {21b}

We have no interim analyses or stopping guidelines as there are no anticipated problems with the majority of trial components that are detrimental to the participants.

Methods for additional analyses (e.g. subgroup analyses) {20b}

Effect modification will be assessed for a-priori-defined subgroups (e.g. district; Government vs private school; age group; baseline examination score; baseline WASH facilities). The cost-effectiveness analysis will include cost–utility analysis comparing costs and utilities of the two groups with costs considered from a provider perspective and health outcomes measured by QALYs based on the Child Health Utility 9D (CHU9D), cost-effectiveness analyses of the intervention effect on SDQ score, and cost–well-being analysis, with costs considered from a provider perspective and outcomes measured by improvement in happiness and life satisfaction scores. To assess bias due to attrition, we will compare reasons for students leaving school, and baseline characteristics associated with dropout, between arms.

Methods in analysis to handle protocol non-adherence and any statistical methods to handle missing data {20c}

We will use intention-to-treat methods for primary and secondary outcomes. The primary analysis includes all female trial participants present at endline and will adjust for relevant baseline measures. We therefore do not need to impute missing endline data.

Plans to give access to the full protocol, participant-level data, and statistical code {31c}

The full protocol will be made available on the study website (https://www.lshtm.ac.uk/research/centres-projects-groups/meniscus), and participant-level data and statistical code will be available through the LSHTM Data Repository (https://datacompass.lshtm.ac.uk/).

Oversight and monitoring

Composition of the coordinating centre and trial steering committee {5d}

The trial sponsor, the London School of Hygiene and Tropical Medicine (LSHTM), will organise monitors to review the source documents as needed, to determine whether the data reported are complete and accurate. The Trial Steering Committee (TSC) is chaired by an independent scientist and consists of 6 further independent members (including Government representatives), 3 observers (including a funding representative), and 7 non-independent members. The Trial Management Group (TMG), chaired by the PI and attended by co-investigators, meet every 1–2 months to oversee trial progress and report to the TSC.

Our research will be communicated to the public and stakeholders in Uganda, the UK, and globally through the trial website and webinars. At the beginning of the trial, we conducted initial stakeholder workshops to introduce the trial to representatives from the Ministry of Education and sports, Ministry of Health representative, district, WoMena Uganda, and schools. At the end of the trial, we will visit each school to hold a facilitated discussion about the findings with the students, parents, and teachers and will offer the intervention to schools randomised to the control arm. We will conduct a stakeholder workshop including local and national stakeholders (school representatives, parents, community leaders, policymakers from the Ministries of Education and Health, NGOs, and other academic researchers) to discuss policy implications of the findings. We are working with the Community Advisory Boards that are composed of representatives of the community participating in the research (parents, adolescents, teachers). Their role is to provide advice on how best to conduct the informed consent process and the implementation of research protocols

Composition of the data monitoring committee, its role, and reporting structure {21a}

The Independent Data Monitoring and Ethics Committee (IDMEC) consists of 3 independent members who are knowledgeable in the subject area, safety monitoring, and clinical trials. One of the members is a statistician to provide independent statistical expertise, especially with regard to interpretation of accumulating data and guidance through the report. The role of IDMEC is to safeguard the interests of trial participants, monitor the main outcome measures, and monitor the overall conduct of the trial. The IDMEC reviews the trial’s progress including updated figures on recruitment, data quality, adherence to protocol treatment and follow-up, and main outcomes and safety data. The IDMEC shares their recommendations with the Trial Steering Committee through the trial statistician, usually within 2 weeks of the meeting. A copy of this will be stored at LSHTM.

Adverse event reporting and harms {22}

Prior to randomisation, the trial clinical officer will map and visit health centres III, IV, district hospitals, and referral hospitals in each district and meet with District Health Officers to confirm referral procedures. Health centres III are sub-county-level clinics led by a senior clinical officer, with a general outpatient clinic, maternity ward, and functioning laboratory. Health centres IV are county or parliamentary constituency-level mini-hospitals, led by a senior medical officer, with in-patient wards for men, women, and children, respectively, and a theatre for emergency operations. Hospitals provide comprehensive medical services, receive referrals from lower health facilities, are relatively equipped with advanced diagnostics, and have advanced capabilities for resuscitation and life support. As part of the intervention, girls will be provided with the toll-free number for Public Health Ambassadors Uganda (PHAU) toll-free number 0800-300-600 and the Marie Stopes Uganda (MSU) contact centre (phone: 0800 220 333; WhatsApp: 754001 503), which operates 7 days per week and is managed by a team of 12 qualified counsellors and 2 nurses to provide confidential advice on sexual and reproductive health and referral to services in Luganda and English.

School nurses or designated person in both arms will be trained to monitor and report all suspected serious adverse events (SAEs) (i.e. death, life-threatening event, hospitalisation, persistent or significant disability or incapacity). These will be assessed by the trial clinical officer and noted in the SAE reporting form, including determination of a possible relationship with the intervention (analgesic use or the menstrual cup). Participants with SAEs will be rapidly referred to previously mapped health centre IVs by the MENISCUS clinical officer or the school or health facility III as appropriate. Transportation to the hospital will be provided by the study if needed. The trial clinical officer will be responsible for initially assigning causality and SAEs will be reported to the trial manager and PI within 24 h, using an SAE form. SAEs that are at least possibly related to the study interventions will be reported to the IDMEC within 24 h of the PI becoming aware of it. If awaiting further details, a follow-up SAE report will be submitted promptly upon receipt of any outstanding information.

Non-serious adverse events will be reported in the intervention arm schools only, following training by the trial clinical officer. Each participant experiencing a non-serious adverse event in intervention arm schools will have a record of their adverse events archived confidentially at the MRC MENISCUS office.

Girls who self-report urogenital symptoms during the endline survey will be referred to a local clinic (both private and government) for syndromic management as per Ugandan clinical guidelines [31], together with the Multistix 8 test result for those with UTI symptoms. The trial clinical officer will provide training to the school nurses on symptom identification and referral.

Frequency and plans for auditing trial conduct {23}

The TSC meets approximately once per year to review trial conduct and progress. The TMG meets approximately every 6 weeks to review trial progress. The IDMEC meet twice a year to review safety issues and trial progress. The study sponsor (LSHTM) is responsible for organising monitors to review the source documents as needed, to determine whether the data reported are complete and accurate. The monitors will audit the overall quality and completeness of the data, examine source documents, interview investigators and coordinators, and confirm that the coordinating centre has complied with the requirements of the protocol. The monitors will verify that all adverse events were documented in the correct format and are consistent with protocol definition.

Plans for communicating important protocol amendments to relevant parties (e.g. trial participants, ethical committees) {25}

Protocol modifications which may impact on the conduct of the study and potential benefit of the patient or may affect patient safety will be approved by the ethics committees as a formal amendment prior to implementation. Administrative changes of the protocol are minor corrections and/or clarifications that have no effect on the way the study is to be conducted. These administrative changes will be agreed upon by the TMG and TSC and will be documented in a memorandum.

Dissemination plans {31a}

Results will be disseminated among schools and local and national stakeholders to discuss policy implications of the findings. Policymakers and partners will be engaged through the Technical Working Groups (TWGs) for Ministry of Education and Ministry of Health. Communication with the wider academic community will include publication of the trial protocol and results as well as the economic, qualitative, and process evaluations in peer-reviewed academic journals with open access, guided by a dissemination plan.

Discussion

Poor menstrual experience can adversely affect education, health, and well-being [5]. Our formative studies among Ugandan secondary school girls in Wakiso District found an unmet need for effective MH interventions to enable girls to better manage both the psychosocial and physical aspects of menstruation, supported by a broad consensus that MH interventions need to address menstrual stigma and literacy as well as the provision of products or improving WASH facilities [17]. We developed the MENISCUS multi-component intervention to address individual, social, behavioural, and environmental barriers to good MH, mental health problems, and educational engagement in line with these findings, and with the social cognitive theory underpinning our research.

To date, most previous MH interventions have focused on either puberty education, provision of menstrual products, or WASH improvements and have largely been conducted in rural primary schools [8, 26]. The MENISCUS intervention is innovative in evaluating a multi-component menstrual health intervention that includes all these components, and also pain management, inclusion of boys to address menstrual-related stigma and improve the school environment. It includes secondary schools in rural and peri-urban areas. The intervention has been co-designed with schools to be culturally appropriate, feasible to deliver, aligned with Government guidelines, cost-effective, environmentally-friendly, and practically sustainable within the schools. If the trial shows the intervention to be cost-effective and acceptable, it will have the potential to be scaled-up nationally and regionally. We will evaluate the implementation of current MoES guidelines in the control arm and in diverse settings, estimate the incremental cost and cost-effectiveness of delivering the MENISCUS package, and estimate scale-up scenarios following Ugandan government guidelines.

A recent systematic review highlighted the lack of evidence on the experience of women and girls participating in MH interventions [32]. The mixed-methods planned process evaluation will assess how the contextual factors (e.g. setting, school, staff, students) affect implementation and perceptions of the intervention. The qualitative data on mechanisms and context and the quantitative subgroup analyses will inform the potential transportability of the intervention. The policy analysis component will facilitate translation of findings to policy and inform refinement of the Ugandan Government MHM guidelines and implementation, including a better understanding of the lack of implementation of the current Circular.
