To investigate the association of obesity with anxiety, depression and emotional well-being (positive and negative affect) in three age groups.
A cross-sectional survey was carried out in Canberra and the neighbouring town of Queanbeyan, Australia, with a random sample from the electoral roll of 2,280 persons aged 20-24, 2,334 aged 40-44, and 2,305 aged 60-64.
Self-reported height and weight were used to classify participants as underweight (body mass index of less than 18.5), acceptable weight (18.5 to less than 25), overweight (25 to less than 30) or obese (30 and over). Obesity in women was associated with more anxiety and depression symptoms and less positive affect, but there were only weak and inconsistent associations in men. When factors that might mediate any association were controlled (physical ill health, lack of physical activity, poorer social support, less education and financial problems), a different picture emerged, with the underweight women having more depression and negative affect and the obese and overweight women tending to have better mental health than the acceptable weight group. Controlling for physical ill health alone accounted for the association of obesity with anxiety and depression in women.
Obesity has an association with anxiety, depression and lower well-being in women, but not in men. The results are consistent with physical ill health playing a mediating role.
Reducing obesity in the population is unlikely to have any direct effect on mental health or emotional well-being.
调查三个年龄组中肥胖与焦虑、抑郁及情绪幸福感（积极和消极情绪）之间的关联。
在澳大利亚堪培拉及其邻近城镇昆比恩进行了一项横断面调查，从选民名单中随机抽取了2280名年龄在20 - 24岁之间、2334名年龄在40 - 44岁之间以及2305名年龄在60 - 64岁之间的人。
通过自我报告的身高和体重将参与者分为体重过轻（体重指数小于18.5）、正常体重（18.5至小于25）、超重（25至小于30）或肥胖（30及以上）。女性肥胖与更多的焦虑和抑郁症状以及更少的积极情绪相关，但男性中仅有微弱且不一致的关联。当控制可能介导任何关联的因素（身体不健康、缺乏体育活动、社会支持较差、教育程度较低和经济问题）时，出现了不同的情况，体重过轻的女性有更多的抑郁和消极情绪，而肥胖和超重的女性往往比正常体重组有更好的心理健康。仅控制身体不健康就解释了女性肥胖与焦虑和抑郁之间的关联。
肥胖与女性的焦虑、抑郁及较低的幸福感相关，但与男性无关。结果与身体不健康起中介作用一致。
降低人群中的肥胖率不太可能对心理健康或情绪幸福感有任何直接影响。
