To examine racial/ethnic differences in the relationship between weight perception and weight management behaviors among overweight and obese adults.
The study examined a nationally representative sample of 11,319 non-Hispanic White, non-Hispanic Black and Mexican American overweight and obese adults aged > or = 20 years from the 1999-2006 National Health and Nutrition Examination Survey.
Body mass index (BMI, defined as weight in kilograms divided by height in meters squared) was used to categorize overweight (25 < or = BMI < 30) and obesity (BMI > or = 30). Measured height and weight were used to calculate BMI. Subjects reported self-perception of weight status (correct perception and misperception) and weight management behaviors over the previous 12 months (trying to lose weight, trying not to gain weight, and having a desired weight goal). Weight perception stratified logistic regression was used to model odds of weight management behavior by race/ethnicity.
Among overweight and obese non-Hispanic White, non-Hispanic Black, and Mexican American adults, correct weight perception was positively associated with weight management behavior. In multiple logistic regression models, overweight non-Hispanic Blacks with a weight misperception were less likely to have tried to lose weight (adjusted odds ratio [aOR] = .7; 95% confidence interval [Cl] = .5,1.0) or to have tried not to gain weight (aOR = .7; 95% CI = .5,1.0) compared to overweight non-Hispanic Whites with a weight misperception. Among the obese with a misperception, non-Hispanic Blacks were less likely to desire to weigh less compared to non-Hispanic Whites (aOR = .5; 95% CI = .3,.9).
Weight perception was associated with weight management behaviors, and this relationship varied by race/ethnicity. Weight perception may need to be addressed among overweight and obese individuals to increase appropriate weight management behaviors, particularly among minority communities.
研究超重和肥胖成年人中，体重感知与体重管理行为之间的关系在不同种族/民族之间的差异。
本研究调查了来自 1999 年至 2006 年全国健康和营养检查调查的 11319 名非西班牙裔白种人、非西班牙裔黑人和墨西哥裔超重和肥胖成年人（年龄>或= 20 岁）的全国代表性样本。
体重指数（BMI，定义为体重（千克）除以身高（米）的平方）用于分类超重（25 <或= BMI < 30）和肥胖（BMI >或= 30）。测量的身高和体重用于计算 BMI。参与者报告了过去 12 个月的自我体重感知状态（正确感知和错误感知）和体重管理行为（试图减肥、试图不增重和有理想的体重目标）。体重感知分层逻辑回归用于模拟种族/民族体重管理行为的几率。
在超重和肥胖的非西班牙裔白种人、非西班牙裔黑人和墨西哥裔美国人成年人中，正确的体重感知与体重管理行为呈正相关。在多变量逻辑回归模型中，体重感知错误的超重非西班牙裔黑人与试图减肥（调整后的优势比[aOR] =.7；95%置信区间[CI] =.5,1.0）或试图不增重（aOR =.7；95% CI =.5,1.0）的可能性低于体重感知错误的超重非西班牙裔白人。在错误感知肥胖的人中，与非西班牙裔白人相比，非西班牙裔黑人不太可能希望体重减轻（aOR =.5；95% CI =.3,.9）。
体重感知与体重管理行为相关，这种关系因种族/民族而异。在超重和肥胖个体中，可能需要解决体重感知问题，以增加适当的体重管理行为，特别是在少数民族社区中。
