The purpose of this study was to examine the associations among television viewing, eating practices, and overweight and health status of a nationally representative sample of adults in the United States.
Data on adults aged 20 years or older from the U.S. Department of Agriculture's Continuing Survey of Food Intakes by Individuals 1994-1996 were used for the study. Participants' socioeconomic and demographic characteristics, macronutrient intakes, weight status, prevalence of health conditions, television viewing, and overweight status were analyzed. Survey design effects were used in the analyses.
More than 2 hours of television viewing per day was associated with a high mean body mass index and overweight or obesity in both men and women. Other characteristics associated with watching more than 2 hours of television per day were being 50 years of age or older, having a high school education or less, living in a household with income below 131% of the federal poverty level, and not being employed. Adults who watched more than 2 hours of television per day had high intakes of energy and macronutrients and were more likely to be overweight. They also obtained more energy from snacks and supper. A higher percentage of adults with health conditions watched more than 2 hours of television per day compared with adults without health conditions.
Obesity intervention programs, especially those aimed at adults who are retired or not employed, should emphasize reducing time spent viewing television or videos or participating in similar sedentary activities and discourage snacking or eating while watching television.
本研究旨在调查美国具有全国代表性的成年人样本中,看电视、饮食习惯与超重及健康状况之间的关联。
本研究使用了美国农业部1994 - 1996年个人食物摄入量持续调查中20岁及以上成年人的数据。分析了参与者的社会经济和人口统计学特征、宏量营养素摄入量、体重状况、健康状况患病率、看电视情况和超重状况。分析中使用了调查设计效应。
每天看电视超过2小时与男性和女性的高平均体重指数以及超重或肥胖有关。与每天看电视超过2小时相关的其他特征包括年龄在50岁及以上、高中及以下学历、生活在收入低于联邦贫困线131%的家庭中以及未就业。每天看电视超过2小时的成年人能量和宏量营养素摄入量较高,更有可能超重。他们从零食和晚餐中获取的能量也更多。与没有健康问题的成年人相比,有健康问题的成年人中每天看电视超过2小时的比例更高。
肥胖干预项目,尤其是针对退休或未就业成年人的项目,应强调减少看电视或视频的时间或参与类似久坐活动的时间,并劝阻在看电视时吃零食或用餐。
