■普通美国家庭的饮食和食品购买模式与联邦建议不同步。研究人员将此与肥胖率的增长联系起来,糖尿病,和其他与饮食有关的疾病在美国餐馆的食物已经被讨论了一个潜在的因素,不健康的饮食,因为它通常是热量密集的。我们使用USDAFoodAPS数据和NPDReCount数据调查了家庭进入餐馆与饮食质量之间的关联。
■我们定义了家庭周围的半径来衡量餐厅的商店数量,并应用了结合家庭特征的回归分析。
■我们发现,无论是餐厅数量还是开放,都与平均饮食质量没有许多统计或经济意义上的关联。家庭特征和人口统计数据在解释饮食质量变化方面要强大得多。
■我们的发现与大量不断增长的实证研究相一致,这些研究表明,在解释食物选择和饮食质量方面,个人偏好和其他家庭特征比食物环境更重要。鉴于现有的关于进入大型超市的重要性的研究,我们的研究结果表明,在解释饮食质量方面,接触食品零售商比接触餐馆更为重要.
UNASSIGNED: The average American household\'s diet and food purchasing patterns are out of sync with federal recommendations. Researchers have connected this with the large and growing rates of obesity, diabetes, and other diet-related ailments in the U.S. Restaurant food has been discussed a potential contributor to unhealthful diets, as it is often calorically dense. We investigate the association between household access to restaurants and diet quality using USDA FoodAPS data and NPD ReCount data.
UNASSIGNED: We define radii around households to measure restaurant outlet counts and apply a regression analysis incorporating household characteristics.
UNASSIGNED: We find that neither restaurant counts nor openings share many statistically or economically significant associations with average dietary quality. Household characteristics and demographics are far more powerful in explaining variation in diet quality.
UNASSIGNED: Our findings align with the large and growing body of empirical research that suggests that personal preferences and other household characteristics are more important than the food environment in explaining food choices and diet quality. Given the extant research on the importance of access to large supermarkets, our results suggest that access to food retailers is more important in explaining diet quality than access to restaurants.
