BACKGROUND
Limited evidence supports a possible association between a person's perception of their weight status and their quality of life (QoL). This study evaluates whether misperception around weight status is associated with QoL and the impact of gender on this association.
METHODS
A cross-sectional survey of Australian adults (n = 1,905 analysed) collected self-reported height and weight (used to estimate BMI), gender and QoL (described using the AQoL-8D). Participants reported whether they perceived their weight status to be 'underweight', 'healthy weight', 'overweight' or 'obese'. Misperception around weight status was categorised based on perceived weight status and self-reported BMI. Ordinary least squares regression was used to test associations between self-reported overall, physical and psychosocial QoL, misperception of weight status, and gender, across different BMI categories, after controlling for income, education, relationship status and health conditions.
RESULTS
Compared to accurate perception, underestimation of weight status was associated with higher overall QoL for obese males and females and for overweight males. Overestimation of weight status was associated with higher overall QoL for underweight females and lower overall QoL for healthy weight males and females. The same pattern was seen for psychosocial QoL. Physical QoL was less sensitive to misperception than psychosocial QoL.
CONCLUSIONS
Self-reported misperception around weight status is associated with overall, psychosocial and to a lesser extent physical QoL in Australian adults, although its role depends on BMI category and gender. Generally misperception in the direction of "healthy weight" is associated with higher QoL and overestimation of weight status by those who are of healthy weight is associated with lower QoL. Findings should be confirmed in datasets that contain measured as opposed to self-report height and weight.
背景
仅有有限的证据支持一个人的体重状况认知与其生活质量（QoL）之间可能存在关联。本研究评估体重状况的认知错误是否与生活质量相关，以及性别对这种关联的影响。
方法
对澳大利亚成年人进行的一项横断面调查（分析了n = 1905人）收集了自我报告的身高和体重（用于估算体重指数）、性别和生活质量（使用AQoL - 8D描述）。参与者报告他们认为自己的体重状况是“体重过轻”“健康体重”“超重”还是“肥胖”。根据感知到的体重状况和自我报告的体重指数对体重状况的认知错误进行分类。在控制了收入、教育程度、恋爱状况和健康状况后，使用普通最小二乘法回归来检验不同体重指数类别中自我报告的总体、身体和心理社会生活质量、体重状况认知错误与性别的关联。
结果
与准确认知相比，体重状况被低估与肥胖男性和女性以及超重男性的总体生活质量较高相关。体重状况被高估与体重过轻女性的总体生活质量较高以及健康体重男性和女性的总体生活质量较低相关。心理社会生活质量也呈现相同模式。身体生活质量对认知错误的敏感度低于心理社会生活质量。
结论
在澳大利亚成年人中，自我报告的体重状况认知错误与总体、心理社会以及在较小程度上与身体生活质量相关，尽管其作用取决于体重指数类别和性别。一般来说，朝着“健康体重”方向的认知错误与较高的生活质量相关，而健康体重者对体重状况的高估与较低的生活质量相关。研究结果应在包含测量而非自我报告的身高和体重的数据集中得到证实。
