As the prevalence of childhood obesity has risen in past decades, more attention has been given to how the neighborhood food environment affects children's health outcomes.
This exploratory study examined the relationship between the presence of neighborhood food stores within a girl's neighborhood and 3-year risk of overweight/obesity and change in BMI, in girls aged 6 or 7 years at baseline.
A longitudinal analysis of participants in the Cohort Study of Young Girls' Nutrition, Environment and Transitions (CYGNET) was conducted from 2005 to 2008. Neighborhood food stores were identified from a commercial database and classified according to industry codes in 2006. Generalized linear and logistic models were used to examine how availability of food stores within 0.25-mile and 1.0-mile network buffers of a girl's residence were associated with BMI z-score change and risk of overweight or obesity, adjusting for baseline BMI/weight and family sociodemographic characteristics. Data were analyzed in 2010.
Availability of convenience stores within a 0.25-mile network buffer of a girl's residence was associated with greater risk of overweight/obesity (OR=3.38, 95% CI=1.07, 10.68) and an increase in BMI z-score (β=0.13, 95% CI=0.00, 0.25). Availability of produce vendors/farmer's markets within a 1.0-mile network buffer of a girl's residence was inversely associated with overweight/obesity (OR=0.22, 95% CI=0.05, 1.06). A significant trend was observed between availability of produce vendors/farmer's markets and lower risk of overweight/obesity after 3 years.
Although food store inventories were not assessed and food store indices were not created, the availability of neighborhood food stores may affect a young girl's weight trajectory over time.
在过去几十年中，儿童肥胖症的患病率有所上升，因此人们越来越关注邻里食品环境如何影响儿童的健康结果。
本探索性研究旨在探讨女孩所在社区内邻里食品店的存在与女孩超重/肥胖风险和 BMI 变化之间的关系，这些女孩在基线时年龄为 6 或 7 岁。
对 2005 年至 2008 年期间参加年轻女孩营养、环境和过渡队列研究（CYGNET）的参与者进行了纵向分析。从商业数据库中确定邻里食品店，并根据 2006 年的行业代码进行分类。使用广义线性和逻辑回归模型来研究女孩居住地 0.25 英里和 1.0 英里网络缓冲区以内的食品店的供应情况如何与 BMIz 分数变化和超重或肥胖风险相关，调整基线 BMI/体重和家庭社会人口统计学特征。数据于 2010 年进行分析。
女孩居住地 0.25 英里网络缓冲区以内的便利商店供应情况与超重/肥胖风险增加相关（OR=3.38，95%CI=1.07，10.68），且 BMIz 分数增加（β=0.13，95%CI=0.00，0.25）。女孩居住地 1.0 英里网络缓冲区以内的农产品供应商/农贸市场供应情况与超重/肥胖风险呈负相关（OR=0.22，95%CI=0.05，1.06）。在 3 年后，观察到农产品供应商/农贸市场供应情况与超重/肥胖风险降低之间存在显著趋势。
尽管没有评估食品店库存，也没有创建食品店指数，但邻里食品店的供应情况可能会影响女孩的体重随时间的变化轨迹。
