Effects of Proximity to Supermarkets on a Randomized Trial Studying Interventions for Obesity

OBJECTIVES: To determine whether proximity to a supermarket modified the effects of an obesity intervention.

METHODS: The study examined 498 children aged 6 to 12 years with a body mass index (BMI) at or above the 95th percentile participating in an obesity trial in Massachusetts in 2011 to 2013. The practice-based interventions included computerized clinician decision support plus family self-guided behavior change or health coaching. Outcomes were 1-year change in BMI z-score, sugar-sweetened beverage intake, and fruit and vegetable intake. 

RESULTS: Living closer to a supermarket is associated with greater improvements in fruit and vegetable intake and weight status in an obesity intervention.
