Engaging in some exercise is associated with weight misperception (ie, overweight and obese participants self-reporting being normal weight or underweight) among adults. Less is known about associations between various types of activity with weight misperception. We examined associations between activity (moderate-vigorous leisure-time, work- and transportation-related physical activity, and sedentary activity) and weight misperception.
We used cross-sectional data from 7992 National Health and Nutrition Examination Survey 2007-2010 participants aged 20+ years with a ≥ 25 body mass index. Logistic regression models were used to estimate activity-weight misperception associations.
Individuals who performed some activity, versus none, were less likely to misperceive their weight (Odds Ratio [OR]: 0.78; 95% Confidence Interval [CI]: 0.66, 0.93). Those who engaged in high levels of transportation activity were more likely to misperceive their weight (OR: 1.29; 95% CI: 1.09, 1.54). Individuals who engaged in medium and high levels of sedentary activity, versus low, were less likely to misperceive their weight (OR: 0.65; 95% CI: 0.57, 0.75 and OR: 0.51; 95% CI: 0.43, 0.61, respectively). Associations varied by sex.
Variation in associations of various types of activity with weight misperception should be considered when developing health promotion programs.
在成年人中，进行一些运动与体重误判（即超重和肥胖参与者自我报告体重正常或体重过轻）有关。关于各类活动与体重误判之间的关联，我们所知较少。我们研究了活动（中度至剧烈的休闲时间活动、与工作和交通相关的体力活动以及久坐活动）与体重误判之间的关联。
我们使用了来自2007 - 2010年全国健康与营养检查调查的7992名年龄在20岁及以上、体重指数≥25的参与者的横断面数据。采用逻辑回归模型来估计活动与体重误判之间的关联。
与不进行任何活动的人相比，进行了一些活动的个体误判自己体重的可能性较小（比值比[OR]：0.78；95%置信区间[CI]：0.66，0.93）。从事高水平交通活动的人更有可能误判自己的体重（OR：1.29；95% CI：1.09，1.54）。与低水平久坐活动的人相比，进行中等水平和高水平久坐活动的个体误判自己体重的可能性较小（分别为OR：0.65；95% CI：0.57，0.75和OR：0.51；95% CI：0.43，0.61）。关联因性别而异。
在制定健康促进计划时，应考虑各类活动与体重误判之间关联的差异。
