To examine weight misperceptions and their predictors and association with weight-related behaviors among low-income, multiethnic, reproductive-age women.
We assessed perceptions of body weight and weight-related behaviors of women aged 18 to 25 attending one of five publicly funded reproductive clinics in Texas between August 2008 and March 2010. Data were collected through self-administered questionnaires and chart review. Overweight and normal-weight women were divided into four categories based on self-perception of their body weight: overweight misperceivers, overweight actual perceivers, normal-weight misperceivers, and normal-weight actual perceivers. Multivariable logistic regression analyses were performed to examine the predictors of misperception and the association with weight-related behaviors.
Twenty-three percent (267/1,162) of overweight and 16% (170/1,062) of normal-weight women were misperceivers. Overweight African-American women were more likely to consider themselves normal weight (28% compared with 15%; odds ratio [OR], 2.84; 95% confidence interval [CI], 1.79-4.50), whereas normal-weight African-American women were less likely than whites to consider themselves overweight (7% compared with 16%; OR 0.40; 95% CI 0.22-0.74). Overweight women who had at least some college education (14% compared with 29%; OR 0.53; 95% CI 0.32-0.86) and used the Internet (18% compared with 28%; OR 0.47; 95% CI 0.31-0.70) were less likely to misperceive their body weight. Normal-weight misperceivers were more likely to report healthy and unhealthy weight-reduction behaviors compared with normal-weight actual perceivers, after adjusting for age, race, ethnicity, and body mass index. Opposite scenarios were observed for overweight misperceivers.
Weight misperception is common among both overweight and normal-weight women of reproductive age. Clinicians should provide patient-specific counseling related to healthy weight management goals that take each patient's perceptions into consideration.
探讨低收入、多民族育龄妇女的体重感知及其预测因素与体重相关行为之间的关系。
我们评估了 2008 年 8 月至 2010 年 3 月期间在德克萨斯州的五家公共资助生殖诊所就诊的 18 至 25 岁女性的体重感知和体重相关行为。数据通过自填问卷和图表审查收集。超重和正常体重的女性根据对自己体重的自我感知分为四组：超重错误感知者、超重实际感知者、正常体重错误感知者和正常体重实际感知者。采用多变量逻辑回归分析来检验感知错误的预测因素及其与体重相关行为的关系。
23%（267/1162）的超重女性和 16%（170/1062）的正常体重女性是错误感知者。超重的非裔美国女性更有可能认为自己体重正常（28%比 15%；优势比[OR]，2.84；95%置信区间[CI]，1.79-4.50），而正常体重的非裔美国女性比白人更不可能认为自己超重（7%比 16%；OR 0.40；95% CI 0.22-0.74）。至少受过一些大学教育的超重女性（14%比 29%；OR 0.53；95% CI 0.32-0.86）和使用互联网的超重女性（18%比 28%；OR 0.47；95% CI 0.31-0.70）不太可能错误感知自己的体重。在调整年龄、种族、民族和体重指数后，与正常体重实际感知者相比，正常体重错误感知者更有可能报告健康和不健康的体重减轻行为。超重错误感知者则出现相反的情况。
体重感知错误在育龄超重和正常体重女性中很常见。临床医生应根据每个患者的感知提供与健康体重管理目标相关的个体化咨询。
