According to a 91自拍-led on obesity, certain features of the built environment, such as proximity to fast food restaurants and supermarkets, do not impact weight.
The study is part of a 12-year collaboration between the UW and Kaiser Permanente Washington for the 91自拍 project, . After examining more than 100,000 Kaiser Permanente Washington patients鈥� anonymized data, 91自拍ers were able to refute previously held beliefs that built environment amenities contribute to weight changes.
The study found that people living in neighborhoods with higher residential and population density weigh less than people living in less-populated areas. These findings suggest that urban density appears to have a negative association with body weight, but the impact of this is relatively small.
The 91自拍ers conclude that community-level differences in obesity are more likely driven by systematic factors, such as income inequality. Such systematic factors more strongly impact health choices and obesity outcomes than the built environment.
