Examine whether use of a grocery list is associated with healthier diet and weight among food desert residents.
Cross-sectional analysis of in-person interview data from randomly selected household food shoppers in 2 low-income, primarily African American urban neighborhoods in Pittsburgh, PA with limited access to healthy foods.
Multivariate ordinary least-square regressions conducted among 1,372 participants and controlling for sociodemographic factors and other potential confounding variables indicated that although most of the sample (78%) was overweight or obese, consistently using a list was associated with lower body mass index (based on measured height and weight) (adjusted multivariant coefficient = 0.095) and higher dietary quality (based on the Healthy Eating Index-2005) (adjusted multivariant coefficient = 0.103) (P < .05).
Shopping with a list may be a useful tool for low-income individuals to improve diet or decrease body mass index.
研究购物清单的使用是否与食物匮乏地区居民更健康的饮食及体重相关。
对宾夕法尼亚州匹兹堡市两个低收入、主要为非裔美国人的城市社区中随机抽取的家庭食品购物者进行面对面访谈数据的横断面分析，这些社区获取健康食品的机会有限。
在1372名参与者中进行多变量普通最小二乘回归，并控制社会人口学因素和其他潜在混杂变量，结果表明，尽管大多数样本（78%）超重或肥胖，但持续使用清单与较低的体重指数（基于测量的身高和体重）（调整后的多变量系数 = 0.095）和较高的饮食质量（基于2005年健康饮食指数）（调整后的多变量系数 = 0.103）相关（P < .05）。
列清单购物可能是低收入个体改善饮食或降低体重指数的有用工具。
