Adherence
Increased availability of fast-food restaurants in a residential neighborhood is associated with higher Body Mass Index (BMI) and higher obesity rates in postmenopausal women.
Living in an area with many fast-food restaurants is linked to higher BMI and obesity rates. This suggests that the ease of accessing unhealthy, energy-dense food contributes to weight gain, even if individual choices are not the sole factor.
GoodSupportsHIGH confidence
Conversely, as fast-food outlet availability increased from the 10th to the 90th percentile, BMI was higher by 0.28 kg/m2... the obesity prevalence rose from 37% to 39% as the availability of fast-food restaurants increased from the 10th to the 90th percentile.
Why this rating
Large sample size and robust statistical modeling, but cross-sectional nature prevents establishing causality.
