Table 6 Environmental characteristics of the Well London CRT LSOAs

From: The Well London program - a cluster randomized trial of community engagement for improving health behaviors and mental wellbeing: baseline survey results

  Control (n = 20) Intervention (n = 20)
Area 1000 m2 - mean 187 (sd 177) 209 (sd 233)
Walkability score a - mean 5.1 (sd 2.7) 3.8 (sd 3.0)
Cyclability score b - mean 0.8 ( sd 0.8) 0.5 (sd 0.5)
Number of fast food outlets - median 0.5 (IQR 0, 4) 1 (IQR 0, 4.5)
Number of general grocery stores and supermarkets - median 0.5 (IQR 0, 1) 0 (IQR 0, 1.5)
Number of shops selling fruit and/or vegetables - median 0 (IQR 0, 0) 0 (IQR 0, 1.5)
Number of communal green spaces - median 9 (IQR 6.5, 19.5) 13.5 (IQR 9, 24)
Signs of home personalisation c - median 1.8 (IQR 1.5, 2.0) 1.6 (IQR 1.1, 2.2)
Neighbourhood watch signs/ prohibitive signs c - median 1.3 (IQR 1.0, 1.4) 1.4 (IQR 1.0, 1.3)
Incivilities d - median 1.1 (IQR 0.6, 1.6) 1.2 (IQR 0.6, 2.1)
  1. aWalkability score calculated as the total number of paved pedestrian areas (not pavement), buffers between the pavement and road, signposts to aid pedestrians (for example, to landmarks such as station, library) and road-crossing aids, standardized by the total area of the LSOA in square meters.
  2. bCyclability score calculated as the total number of non-continuous and continuous cycle lanes and bike storage facilities, standardized by the total area of the LSOA in square meters.
  3. cMean score across all segments where: 1, none; 2, little; 3, moderate; 4, a lot.
  4. dComposed of litter/broken glass, graffiti, broken/vandalized facilities, broken windows, security measures, unattended dogs, large dumped items in public space, dog foul, hyperdermic needles and syringes, alcohol bottles/cans, sex paraphernalia and condoms. Each item was rated: 1, none; 2, little; 3, moderate; 4, a lot. The composite score is the mean number of items across all segments assessed in an LSOA that were rated moderate or a lot.
  5. IQR, interquartile range; sd, standard deviation.
