背景尽管人们普遍认为外出就餐越来越受欢迎，而且可能导致美国人口肥胖率增加，但关于这一主题的公开数据很少。为了解决这个问题，我们研究了消费频率的趋势商业准备（CP）膳食报告的美国人年龄大于或等于18岁，其营养相关性。数据来自1987年全国健康访谈调查（NHIS）（n = 21，731），1992年NHIS（n = 11，718）和1999-2000年全国健康与营养检查调查（NHANES）（n = 5，330）。有关CP膳食消费的信息来自三次调查中的问题。采用多元线性回归分析方法，对报告的CP餐频率与体重指数（BMI）、能量和常量营养素摄入的独立相关性进行了研究。1987年和1992年报告的每周CP餐平均数为2.5，1999-2000年为2.8。1987年，大约28%的人口报告0或
Background. Despite widely held beliefs about increasing popularity of eating away-from-home and its possible contribution to increasing adiposity of the US population, there are little published data on this topic. To address this issue, we examined trends in frequency of consumption of commercially prepared (CP) meals reported by Americans aged greater than or equal to 18 years, and its nutritional correlates.Methods. The data were from the National Health Interview Survey (NHIS) 1987 (n = 21,73 1), NHIS 1992 (n = 11,718), and the National Health and Nutrition Examination Survey (NHANES) 1999-2000 (n = 5,330). The information on CP meal consumption was obtained from questions included in the three surveys. The independent association of reported CP meal frequency with body mass index (BMI), and intakes of energy and macronutrients was examined using multiple linear regression methods.Results. The mean reported number of CP meals per week was 2.5 in 1987 and 1992, and 2.8 in 1999-2000. In 1987, approximately 28% of the population reported 0 or
