Are adults living in disadvantaged communities less likely to recognize or be dissatisfied with being overweight than their counterparts in more affluent areas? Multilevel logistic regression was used to analyze a cross-sectional sample of 10 880 people aged 15 years or older selected from the 2009 wave of the 'Household, Income and Labour Dynamics in Australia'. Outcome variables included whether participants perceived themselves as 'overweight' or not, and their self-reported (dis)satisfaction with their weight. Key covariates included: (i) actual weight status, derived from the World Health Organization (WHO) criteria for 'normal', 'overweight' and 'obese' intervals of body mass index, on the basis of self-reported height and weight; and (ii) the Socio-Economic Index For Areas, an indicator of neighborhood socioeconomic disadvantage defined for Census Collection Districts. Data were analyzed in 2015. In more disadvantaged neighborhoods, self-classification as overweight or obese tended to be higher, but dissatisfaction with current weight appeared to be lower. For people who by WHO criteria are of 'normal' weight, 16.8% (95% CI 15.6, 17.9) felt dissatisfied with their weight and 11.5% (95% CI 10.5, 12.5) classified themselves as overweight or obese. For people classified as overweight or obese by these criteria, the level of dissatisfaction and perceived overweight or obese status were much higher. Overweight and obese participants in affluent areas were more likely to be dissatisfied and consider themselves overweight or obese in comparison with their peers living in disadvantaged areas. Interventions aiming to prevent weight gain and to narrow socioeconomic inequity in overweight must reconcile with the findings that people in disadvantaged communities are less likely to recognize their overweight or be dissatisfied with their weight status.
与生活在更富裕地区的成年人相比，生活在弱势社区的成年人是否不太可能意识到自己超重或对超重感到不满？采用多水平逻辑回归分析了从2009年“澳大利亚家庭、收入和劳动力动态”调查中选取的10880名15岁及以上人群的横断面样本。结果变量包括参与者是否认为自己“超重”以及他们自我报告的对体重的（不）满意程度。关键协变量包括：（i）根据自我报告的身高和体重，依据世界卫生组织（WHO）的体重指数“正常”“超重”和“肥胖”区间标准得出的实际体重状况；以及（ii）地区社会经济指数，这是为人口普查收集区定义的邻里社会经济劣势指标。数据于2015年进行分析。在更弱势的社区中，自我归类为超重或肥胖的比例往往更高，但对当前体重的不满程度似乎更低。对于按照WHO标准体重“正常”的人，16.8%（95%可信区间15.6，17.9）对自己的体重感到不满，11.5%（95%可信区间10.5，12.5）将自己归类为超重或肥胖。对于按照这些标准归类为超重或肥胖的人，不满程度以及感知到的超重或肥胖状态要高得多。与生活在弱势地区的同龄人相比，富裕地区的超重和肥胖参与者更有可能感到不满并认为自己超重或肥胖。旨在预防体重增加和缩小超重方面社会经济不平等的干预措施必须与以下研究结果相协调，即弱势社区的人们不太可能意识到自己超重或对自己的体重状况感到不满。
