目的：探讨成年人进餐频率与肥胖的关系。研究方法和方法：采用食物频率问卷调查了73名健康男女[年龄19~80岁，体重指数(BMI)18~33]，对7种不同餐馆(炸鸡、汉堡、披萨、中式、墨西哥、炸鱼和其他)的日常自由生活饮食摄入量和食物消费频率进行了调查。此外，通过水压称重法测定体脂(体重百分比)，并通过问卷调查评估体力活动和其他生活方式参数。在控制了年龄、性别和其他混杂因素后，采用多元回归分析方法确定了餐饮频率与体脂的关系。结果：餐饮消费平均7.5+/-8.5(标准差)次/月。在控制了年龄和性别因素后，饮食频度与体脂呈正相关(偏相关系数r=0.36，p=0.003)。在控制了教育水平、吸烟状况和酒精摄入量后，这种联系的强度没有改变，但在额外控制体力活动后，偏相关系数增加到0.42%(p=0.004)。能量、脂肪和纤维的每日总摄入量与餐馆食物消费频率显著相关(r分别为0.59、0.28和-0.45，p=0.02~0.0001)。因此，美国家庭食物收入中花在外出准备食物上的比例越来越高，这可能有助于解释全国肥胖率不断上升的原因。
Purpose: To examine the association between the frequency of consuming restaurant food and body fatness in adults.Research Methods and Procedures: Usual free-living dietary intake and the frequency of consuming food from seven different restaurant types (fried chicken, burger, pizza, Chinese, Mexican, fried fish, and "other") were assessed by food frequency questionnaire in 73 healthy men and women [ages 19 to 80, body mass index (BMI) 18 to 33]. In addition, body fatness (percent weight) was determined by hydrostatic weighing, and physical activity and other lifestyle parameters were assessed by questionnaire. The relationship between the frequency of consuming restaurant food and body fatness was determined after controlling for age, sex, and other confounders by using multiple regression techniques.Results: Restaurant food consumption averaged 7.5+/-8.5 (Standard Deviation) times/month. After controlling for age and sex, the frequency of consuming restaurant food was positively associated with body fatness (partial r=0.36, p=0.003). The strength of this association did not change after controlling for education level, smoking status, and alcohol intake, but after additionally controlling for physical activity, the partial r increased to 0.42 (p=0.004). Total daily intakes of energy, fat, and fiber were significantly associated with restaurant food consumption frequency (r=0.59, 0.28, and -0.45, respectively, p=0.02 to 0.0001).Discussion: The frequency of consuming restaurant food was positively associated with increased body fatness in adults. The increasing proportion of household food income spent on food prepared away from home in the United States may therefore help explain the rising national prevalence of obesity.
