Objective: 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., Research Methods and Procedures: 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., Results: 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., Discussion: 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.

Background: Trying to lose weight is a concern for many Americans, but motivation for weight loss is not fully understood. Clinical assessment for obesity treatment is primarily based on measures of body size and physical comorbidities; however, these factors may not be enough to motivate individuals to lose weight. Health-related quality of life (HRQOL) may have a role in an individual's decision to try to lose weight. The objective of this study was to examine the prevalence and association of HRQOL measures as independent moderators of weight loss practices among overweight and obese men and women., Research Methods and Procedures: Data were from the 2003 Behavioral Risk Factor Surveillance System, an annual state-based telephone survey of the civilian noninstitutionalized population of adults 20 years of age or older with BMI > or = 25.0 kg/m2 (n = 111,456) who responded to 4 standard HRQOL measures that assessed general health status, physical health, mental health, and activity limitation in the past 30 days., Results: Among men with BMI 25-34.9 kg/m2, the odds of trying to lose weight increased for the moderate vs best category of HRQOL but not for the poorest vs best category, and no associations were noted for men with BMI > or = 35 kg/m2. Women with BMI 25-34.9 kg/m2 had reduced odds and decreasing associated trends in the prevalence of trying to lose weight with poorer general health, increased physically unhealthy days, and increased activity limitation days. Conversely, women with 1-13 vs 0 mentally unhealthy days had greater odds of trying to lose weight. Among those trying to lose weight, reducing calories was common (52%-69%, men; 56%-69%, women). Among men, with the exception of recent mental health, poorer levels of HRQOL measures were associated with diminished attainment of recommended physical activity levels. Among women, poorer general health status was associated with diminished attainment of recommended physical activity levels., Discussion: With the exception of recent mental health, HRQOL was differentially associated with trying to lose weight among men and women. Specifically, moderately poor HRQOL among men and better HRQOL among women were associated with trying to lose weight. Consideration of these influences on weight loss may be useful in the treatment and support of obese patients.
