We examine the relationship between weight management practices and diet quality.
Regressions were used to analyze the associations between self-reported weight management methods and diet quality, as measured by the Healthy Eating Index-2005 (HEI-2005), of 1,933 respondents who tried to lose or not gain weight in the 2003-2004 National Health and Nutrition Examination Survey (NHANES). The regressions controlled for sociodemographics, lifestyle behaviors, and other health-related behaviors and perceptions.
Including both switching to foods with lower calories and exercise in weight management was associated with better diet quality, i.e., a higher total HEI-2005 score and higher scores in eight of the twelve HEI-2005 components than including neither method. The eight components included six components on fruit, vegetables and grains, milk, and calories from solid fat, alcohol beverages, and added sugars. Similar but smaller associations were also found among those who reported including either switching to foods with lower calories or exercise.
Based on self-reported data, the findings suggest that including switching to lower calorie foods and exercise in weight management, as recommended by the Dietary Guidelines for Americans (DGA), is associated with diet quality that is more consistent with the key diet-related advice of the DGA.
我们研究了体重管理实践与饮食质量之间的关系。
利用回归分析方法,分析了 1933 名试图减肥或保持体重的受访者的自我报告体重管理方法与饮食质量(采用 2005 年健康饮食指数(HEI-2005)进行衡量)之间的关联。回归分析控制了社会人口统计学因素、生活方式行为以及其他与健康相关的行为和认知。
将饮食中低热量食物的转换和运动纳入体重管理中与更好的饮食质量相关,即总 HEI-2005 评分较高,且在 HEI-2005 的 12 个成分中有 8 个成分的评分较高,这 8 个成分包括水果、蔬菜和谷物、牛奶以及来自固体脂肪、酒精饮料和添加糖的热量。在报告包括饮食中低热量食物的转换或运动的人群中,也发现了类似但较小的关联。
基于自我报告数据,研究结果表明,按照《美国人膳食指南》(DGA)的建议,将饮食中低热量食物的转换和运动纳入体重管理中,与更符合 DGA 关键饮食相关建议的饮食质量有关。
