BACKGROUND/OBJECTIVES: In the African region, little is known about weight misperception among overweight or obese adults. We assessed the prevalence of weight misperception and predictors of weight misperception among overweight or obese adults in Mauritius. Height, weight, and self-perception of weight status data from 5736 adults (≥19 years of age), sampled in a population-based survey in 2009 were analysed. Weight status was defined using BMI calculated on the basis of measured height and weight. Information regarding self-perceived body weight, socio-demographic and self-rated health data were collected using a questionnaire.
Overall 41% of overweight or obese adults misclassified their own weight status. Among adults who were overweight or obese, weight misperception was increasingly less likely among those with increasing education (men: p=0.02; women: p≤0.001) but was more likely among those who perceived their overall health as good or excellent (men: PR=1.29, 95% CI 1.10-1.52; women: PR=1.42, 95% CI 1.26-1.60). Adults who were overweight or obese, weight misperception was increasingly less likely with increasing income (men: p=0.025; women: p≤0.001). Among women who were overweight or obese, weight misperception was increasingly more likely with increasing age (p≤0.001) and those who self-reported Chinese ethnicity (PR=1.48, 95% CI 1.22-1.78).
A large proportion of adults in Mauritius misperceive their own weight status, with variation by socio-demographic characteristics and self-rated health. Future studies are needed to examine if correcting misperceptions of weight status may support obesity prevention and control efforts in Mauritius.
背景/目的：在非洲地区，对于超重或肥胖成年人的体重误判情况知之甚少。我们评估了毛里求斯超重或肥胖成年人中体重误判的患病率及其预测因素。对2009年一项基于人群的调查中抽取的5736名成年人（≥19岁）的身高、体重及体重状况自我认知数据进行了分析。体重状况根据基于测量身高和体重计算出的BMI来定义。使用问卷收集了关于自我感知体重、社会人口统计学特征及自我评定健康状况的数据。
总体而言，41%的超重或肥胖成年人对自己的体重状况判断错误。在超重或肥胖的成年人中，随着受教育程度的提高，体重误判的可能性越来越小（男性：p = 0.02；女性：p≤0.001），但那些认为自己总体健康状况良好或极佳的人出现体重误判的可能性更大（男性：PR = 1.29，95%置信区间1.10 - 1.52；女性：PR = 1.42，95%置信区间1.26 - 1.60）。超重或肥胖的成年人中，随着收入增加，体重误判的可能性越来越小（男性：p = 0.025；女性：p≤0.001）。在超重或肥胖的女性中，随着年龄增长，体重误判的可能性越来越大（p≤0.001），且自我报告为华裔的女性出现体重误判的可能性更大（PR = 1.48，95%置信区间1.22 - 1.78）。
毛里求斯很大一部分成年人对自己的体重状况存在误判，且因社会人口统计学特征和自我评定健康状况而异。未来需要开展研究，以检验纠正体重状况误判是否有助于毛里求斯的肥胖预防和控制工作。
