I used longitudinal data to consider the relationship between the neighborhood food environment and adult weight status.
I combined individual-level data on adults from the 1998 through 2004 survey years of the National Longitudinal Survey of Youth 1979 with zip code-level data on the neighborhood food environment. I estimated ordinary least squares models of obesity, body mass index (BMI), and change in BMI.
For residents of urban areas, the neighborhood density of small grocery stores was positively and significantly related to obesity and BMI. For individuals who moved from a rural area to an urban area over a 2-year period, changes in neighborhood supermarket density, small grocery store density, and full-service restaurant density were significantly related to the change in BMI over that period.
Residents of urban neighborhoods with a higher concentration of small grocery stores may be more likely to patronize these stores and consume more calories because small grocery stores tend to offer more unhealthy food options than healthy food options. Moving to an urban area may expose movers to a wider variety of food options that may influence calorie consumption.
我利用纵向数据来研究社区食品环境与成年人体重状况之间的关系。
我将成年人的个体层面数据与社区食品环境的邮政编码层面数据相结合，这些数据来自于 1998 年至 2004 年的全国青年纵向调查 1979 年调查年。我使用普通最小二乘法模型来估计肥胖、体重指数（BMI）和 BMI 变化。
对于城市地区的居民来说，小型杂货店的邻里密度与肥胖和 BMI 呈正相关且显著相关。对于在两年内从农村地区搬到城市地区的个体来说，社区超市密度、小型杂货店密度和全方位服务餐厅密度的变化与该期间 BMI 的变化显著相关。
城市邻里中小型杂货店密度较高的居民可能更倾向于光顾这些商店并消费更多的卡路里，因为小型杂货店往往提供更多不健康的食品选择而不是健康的食品选择。搬到城市地区可能会使搬入者接触到更多种类的食品选择，这可能会影响卡路里的摄入。
