To examine the prevalence and correlates of trying to lose weight among U.S. adults, describe weight loss strategies, and assess attainment of recommendations for weight control (eating fewer calories and physical activity).
This study used the Behavioral Risk Factor Surveillance System, a state-based telephone survey of adults > or =18 years of age (N = 184,450) conducted in the 50 states, the District of Columbia, and Puerto Rico in 2000.
The prevalence of trying to lose weight was 46% (women) and 33% (men). Women reported trying to lose weight at a lower BMI than did men; 60% of overweight women were trying to lose weight, but men did not reach this level until they were obese. Adults who had a routine physician checkup in the previous year and reported medical advice to lose weight vs. checkup and no medical advice to lose weight had a higher prevalence of trying to lose weight (81% women and 77% men vs. 41% women and 28% men, respectively). The odds of trying to lose weight increased as years of education increased. Among respondents who were trying to lose weight, approximately 19% of women and 22% of men reported using fewer calories and > or =150 min/wk leisure-time physical activity.
A higher percentage of women than men were trying to lose weight; both sexes used similar weight loss strategies. Education and medical advice to lose weight were strongly associated with trying to lose weight. Most persons trying to lose weight were not using minimum recommended weight loss strategies.
研究美国成年人尝试减肥的患病率及其相关因素，描述减肥策略，并评估体重控制建议（减少热量摄入和进行体育锻炼）的达成情况。
本研究采用行为危险因素监测系统，于2000年在美国50个州、哥伦比亚特区和波多黎各对18岁及以上成年人进行基于州的电话调查（N = 184,450）。
尝试减肥的患病率女性为46%，男性为33%。女性报告在BMI较低时就开始尝试减肥；60%的超重女性在尝试减肥，而男性直到肥胖才达到这一比例。上一年接受过常规医生检查并收到减肥医学建议的成年人与接受检查但未收到减肥医学建议的成年人相比，尝试减肥的患病率更高（女性分别为81%和41%，男性分别为77%和28%）。尝试减肥的几率随着受教育年限的增加而增加。在尝试减肥的受访者中，约19%的女性和22%的男性报告减少了热量摄入并每周进行至少150分钟的休闲体育活动。
尝试减肥的女性比例高于男性；两性采用的减肥策略相似。接受减肥教育和医学建议与尝试减肥密切相关。大多数尝试减肥的人未采用建议的最低减肥策略。
