Home and neighbourhood built environment features in family‐based treatment for childhood obesity. Issue 3 (31st October 2018) - Hayes, J. F.
Summary: Background: Family‐based behavioural weight loss treatment (FBT) for childhood obesity helps families develop strategies to facilitate healthy choices in their home and other environments (e.g. home neighbourhood). The current study examines how the home food environment, both pre‐FBT and post‐FBT, and the neighbourhoods in which families live are associated with child weight and weight‐related outcomes in FBT. Methods: Parent–child dyads ( n = 181) completed a 16‐session FBT programme and completed home environment, anthropometric and child dietary/activity assessments at pre‐FBT and post‐FBT. Parents reported on availability of food, electronics and physical activity equipment in the home. The neighbourhood food and recreation environments around each dyad's residence was characterized using existing data within a geographic information system. Results: Families successfully made healthy home environment modifications during FBT. Regression models showed reducing RED (e.g. high‐energy‐dense and low‐nutrient‐dense) foods and electronics in the home during FBT had positive effects on child weight and weight‐related outcomes. No neighbourhood food or recreation environment variables were significantly related to outcomes, although having a larger density of public recreation spaces was associated with increases in physical activity at the trend‐level. Conclusions: Modifying the home environment, specifically reducing RED foods and electronics, may be particularly important for FBT success.
