To examine the prevalence and association of activity/participation limitation with trying to lose weight and weight loss practices (eating fewer calories, physical activity, or both) among overweight and obese adults in the United States.
Eligible adults were 20 years of age or older with a body mass index (BMI) >or= 25 kg/m(2) (n = 5608) who responded to standard physical functioning questions included in the 1999-2002 National Health and Nutrition Examination Survey, a continuous survey of the civilian non-institutionalized US population.
Obese (BMI >or= 30) men with vs. without activity/participation limitations were more likely to try to lose weight (OR = 1.59, 95% CI 1.05-2.41). This was not the case for overweight women and men (BMI 25-29.9), or obese women. Among adults trying to lose weight, reducing calorie consumption was common (63%-73%, men, 67%-76%, women). Overweight women with vs without activity/participation limitations had significantly reduced likelihood of attaining recommended physical activity (OR = 0.56, 95% CI 0.36-0.89). Obese adults were more likely to try to lose weight if they attributed their limitation to body weight (OR = 1.78, 95% CI 1.11-2.88) or diabetes (OR = 1.86, 95% CI 1.01-3.43) compared to other causes. Overweight and obese adults who attributed activity/participation limitations to mental health, musculoskeletal, or cardiovascular problems were equally likely to attempt weight loss when respondents with each condition were compared to respondents without the condition.
These results verify the importance of adequate subjective health assessment when developing individual weight loss plans, and may help guide weight management professionals in the development and delivery of more personalized care.
研究美国超重和肥胖成年人中活动/参与受限与试图减肥及减肥方法（减少热量摄入、进行体育活动或两者兼有）之间的患病率及关联。
符合条件的成年人年龄在20岁及以上，体重指数（BMI）≥25 kg/m²（n = 5608），他们对1999 - 2002年国家健康和营养检查调查中包含的标准身体功能问题进行了回答，该调查是对美国非机构化平民人口的连续性调查。
有活动/参与受限的肥胖（BMI≥30）男性比无活动/参与受限的肥胖男性更有可能试图减肥（比值比[OR]=1.59，95%置信区间[CI] 1.05 - 2.41）。超重女性和男性（BMI 25 - 29.9）以及肥胖女性则并非如此。在试图减肥的成年人中，减少热量摄入很常见（男性为63% - 73%，女性为67% - 76%）。有活动/参与受限的超重女性比无活动/参与受限的超重女性达到推荐体育活动量的可能性显著降低（OR = 0.56，95% CI 0.36 - 0.89）。与其他原因相比，如果肥胖成年人将其受限归因于体重（OR = 1.78，95% CI 1.11 - 2.88）或糖尿病（OR = 1.86，95% CI 1.01 - 3.43），则他们更有可能试图减肥。将活动/参与受限归因于心理健康、肌肉骨骼或心血管问题的超重和肥胖成年人，与无这些情况的受访者相比，尝试减肥的可能性相同。
这些结果证实了在制定个人减肥计划时进行充分主观健康评估的重要性，并可能有助于指导体重管理专业人员制定和提供更个性化的护理。
