目的本研究旨在探讨非西班牙裔黑人和非西班牙裔白人青少年的家庭食物供应和食物消费的共同环境与水果、蔬菜和脂肪摄入量的相关性。参与者和设计青少年（n = 144名黑人，84名白人）及其父母在城市青少年健康诊所完成了一项横断面调查。这项青少年调查包括水果、蔬菜和脂肪摄入量的筛查措施，以及与家人一起吃饭、看电视和在三种类型的餐馆吃饭的频率。家长们提供了家中食物供应的信息。主要结果与水果、蔬菜和脂肪消耗相关。统计分析变量间的Spearman相关性，平均比较的t检验，分别对黑人和白人青少年进行多元逐步回归。结果在多元回归中，除了白人青少年的水果摄入量外，家庭可用性与水果、蔬菜或脂肪摄入量没有显著相关。在非快餐店就餐是蔬菜摄入量的最积极预测因素。对于黑人和白人青少年来说，在快餐店和自助餐厅就餐以及边看电视边吃东西是脂肪摄入量的最有力预测因素。结论：与去餐馆吃饭和边看电视边吃饭相比，在家对黑人和白人青少年的水果、蔬菜和脂肪消费的影响相对较小。青少年营养干预方案的目标不应仅仅是健康食品的可获得性，还应包括获取的便利性，例如准备水果和蔬菜，使其美味可口，便于食用。
Objective This study sought to explore home food availability and common settings of food consumption as correlates of fruit, vegetable, and fat intake among a sample of non-Hispanic black and non-Hispanic white adolescents.Participants and design Adolescents (n = 144 black, 84 white) and their parents completed a cross-sectional survey in an urban adolescent health clinic. The adolescent survey included screening measures for fruit, vegetable, and fat intake and items on frequency of eating meals with family, while watching television, and at three types of restaurants. Parents provided information on home availability of foods.Main outcomes Correlates of fruit, vegetable, and fat consumption.Statistical analysis Spearman correlations for associations among variables, t tests for mean comparisons, and multiple stepwise regression conducted separately for black and white adolescents.Results In multiple regression, home availability was not significantly associated with fruit, vegetable, or fat intake except for fruit intake among white adolescents only. Use of non-fast-food restaurants was the strongest positive predictor of vegetable intake. For both black and white adolescents, fast-food and buffet restaurant use and eating while watching television were the strongest predictors of fat intake.Conclusions Compared with restaurant use and eating while watching television, home availability had a relatively small impact on fruit, vegetable, and fat consumption for both black and white adolescents. Intervention programs on adolescent nutrition should target not just availability of healthful foods, but also ease of access, such as the preparation of fruits and vegetables so that they are flavorful and ready to eat.
