Abstract

OBJECTIVE

To examine the prevalence and association of health-related quality of life (HRQOL) with trying to lose weight and with weight loss practices (eating fewer calories, physical activity, and both) among overweight and obese U.S. adults >/= 20 years of age.

RESEARCH METHODS AND PROCEDURES

This study used data from the 2001 to 2002 National Health and Nutrition Examination Survey, a continuous annual survey of the civilian non-institutionalized U.S. population. This analysis included those > or = 20 years of age with BMI > or = 25 (n = 2578) who responded to four standard HRQOL measures that assessed general health status and recent physical health, mental health, and activity limitation.

RESULTS

Among obese men, but not women, there were significant increasing linear trends in the adjusted prevalence of trying to lose weight as physically unhealthy and activity limitation days increased. Regardless of BMI or HRQOL, reducing calories was a common weight loss practice (66% to 86%). Except for recent activity limitation, respondents with BMI > or = 35 did not generally differ by HRQOL level in the attainment of recommended physical activity either alone or in combination with reduced calories, whereas those in the BMI 25 to 34.9 groups often differed significantly by HRQOL level. Specifically, increased unhealthy or activity limitation days were associated with reduced prevalence of attained physical activity.

DISCUSSION

Our findings indicate an association between trying to lose weight and a greater number of unhealthy days reported by obese men, suggesting that these men may be influenced by traditional clinical weight-loss counseling that is prompted by weight and comorbidity, whereas women had a high prevalence of trying to lose weight irrespective of weight and HRQOL. Assessment of HRQOL, especially measures that evaluate physical domains, could provide subjective information to assist with weight counseling.

摘要

目的

研究美国20岁及以上超重和肥胖成年人中，与试图减肥以及减肥行为（减少热量摄入、进行体育活动或两者兼有）相关的健康相关生活质量（HRQOL）的患病率及关联。

研究方法与步骤

本研究使用了2001年至2002年美国国家健康与营养检查调查的数据，这是一项对美国非机构化平民人口的年度连续性调查。该分析纳入了年龄≥20岁、体重指数（BMI）≥25的人群（n = 2578），这些人对四项评估总体健康状况以及近期身体健康、心理健康和活动受限情况的标准HRQOL指标进行了回应。

结果

在肥胖男性中，而非女性中，随着身体不健康天数和活动受限天数增加，试图减肥的校正患病率呈现显著上升的线性趋势。无论BMI或HRQOL如何，减少热量摄入都是常见的减肥行为（66%至86%）。除了近期活动受限外，BMI≥35的受访者在单独或与减少热量摄入相结合达到推荐体育活动方面，一般不会因HRQOL水平而有所不同，而BMI在25至34.9组的受访者通常会因HRQOL水平而有显著差异。具体而言，不健康天数或活动受限天数增加与达到体育活动的患病率降低相关。
