在美国，超重和肥胖的情况正在增加。饮食和体力活动的改变对体重控制很重要。目的检查美国成年人中试图减肥或保持体重的流行率，并描述体重控制策略。设计行为风险因素监测系统，这是一项由州卫生部门于1996年进行的随机数字电话调查。设定参与调查的49个州(和哥伦比亚特区)。参与者年龄在18岁及以上(N=107 804)。主要结果测量报告了当前体重和目标体重，减肥或维持体重尝试的流行率，以及控制体重的策略(少吃卡路里，少吃脂肪，结果男性试图减肥和保持体重的比例分别为28.8%和35.1%，女性分别为43.6%和34.4%。在那些试图减肥的人中，一个常见的策略是减少脂肪的摄取，但不能减少卡路里的摄入(34.9%的男性和40.0%的女性)；只有21.5%的男性和19.4%的女性报告使用了推荐的组合，即少吃卡路里和每周至少进行150分钟的休闲体育活动。在试图减肥的男性中，体重中值为90.4公斤，目标体重为81.4公斤。女性体重中位数为70.3公斤，目标体重为59.0公斤。结论减肥和维持体重是美国男性和女性共同关心的问题。大多数试图减肥的人没有使用推荐的组合，即减少卡路里摄入量和每周进行150分钟或更多的休闲体育活动。
Context Overweight and obesity are increasing in the United States. Changes in diet and physical activity are important for weight control.Objectives To examine the prevalence of attempting to lose or to maintain weight and to describe weight control strategies among US adults.Design The Behavioral Risk Factor Surveillance System, a random-digit telephone survey conducted in 1996 by state health departments.Setting The 49 states (and the District of Columbia) that participated in the survey.Participants Adults aged 18 years and older (N = 107 804).Main Outcome Measures Reported current weights and goal weights, prevalence of weight loss or maintenance attempts, and strategies used to control weight (eating fewer calories, eating less fat, or using physical activity) by population subgroup.Results The prevalence of attempting to lose and maintain weight was 28.8% and 35.1% among men and 43.6% and 34.4% among women, respectively. Among those attempting to lose weight, a common strategy was to consume less fat but not fewer calories (34.9% of men and 40.0% of women); only 21.5% of men and 19.4% of women reported using the recommended combination of eating fewer calories and engaging in at least 150 minutes of leisure-time physical activity per week. Among men trying to lose weight, the median weight was 90.4 kg with a goal weight of 81.4 kg. Among women, the median weight was 70.3 kg with a goal weight of 59.0 kg.Conclusions Weight loss and weight maintenance are common concerns for US men and women. Most persons trying to lose weight are not using the recommended combination of reducing calorie intake and engaging in leisure-time physical activity 150 minutes or more per week.
