Formative study
Study objective Primary outcome variables Independent variable Control variables Type of analysis
 1. To establish local contexts and norms, which contribute to maternal infant and young child nutrition (MIYCN) practices so as to customize the intervention package Factors that influence breastfeeding and other MIYCN practices Not applicable Not applicable Thematic
 2. To identify facilitating factors and barriers that may influence the implementation of BFCI Facilitating factors and barriers to the implementation of BFCI Not applicable Not applicable Thematic
Cluster randomized trial
Study objective Outcome variables Independent variable Control variables Type of analysis
 1. To determine the effectiveness of the BFCI on the rates of exclusive breastfeeding for the first 6 months Exclusive breastfeeding (EBF) at 6 months, 4 months and 2 months Intervention status SES, food security, water and sanitation, maternal characteristics, antenatal care Multinomial logistic regression
 2. To determine the effectiveness of BFCI strategy on MIYCN knowledge and attitudes a. Knowledge levels on MIYCN Intervention status SES, food security, water and sanitation, maternal characteristics, antenatal care Logistic regression
b. Attitudes on MIYCN
 3. To determine the effectiveness of the BFCI on rate of initiation of breastfeeding within the first hour of birth and its implications on successful EBF for the first 6 months Initiation of breastfeeding within 1 hour Intervention status SES, food security, water and sanitation, maternal characteristics, antenatal care Logistic regression
