Participants: 1278 participants took part in the study (58% female). Complete data on adiposity (body mass index [BMI] and fat mass %) were available for 1240 participants (97%); of these a sub-set of 1107 participants (89%) met the inclusion criteria for analyses of accelerometer-based measurements of PA. We examined associations between housing sector sought, neighbourhood perceptions (covariates) and PA and adiposity (dependent variables) adjusted for household clustering, sex, age group, ethnic group, and limiting longstanding illness.
Results: Participants seeking social housing had the fewest daily steps (8304, 95%CI 7959,8648) and highest BMI (26.0kg/m 2 95%CI 25.5,26.5kg/m 2 ) compared with those seeking intermediate (daily steps 9417, 95%CI 9106,9731; BMI 24.8kg/m 2 95%CI 24.4,25.2kg/m 2 ) or market-rent housing (daily steps 9313, 95%CI 8858,9768; BMI 24.6kg/m 2 95%CI 24.0,25.2kg/m 2 ). Those seeking social housing had lower levels of PA (by 19-42%) at weekends vs weekdays, compared with other housing groups. Positive perceptions of neighbourhood quality were associated with higher steps and lower BMI, with differences between social and intermediate groups reduced by ~10% following adjustment, equivalent to a reduction of 111 for steps and 0.5kg/m2 for BMI.
