Obesity is known to increase the risk of many diseases and reduce overall quality of life. This study examines the relationship with self-reported health (SRH) and happiness.
We conducted a cross-sectional study of the 163 066 UK Biobank participants who completed the happiness rating. The association between adiposity and SRH and happiness was examined using logistic regression. SRH was defined as good (excellent, good), or poor (fair, poor). Self-reported happiness was defined as happy (extremely, very, moderately) or unhappy (moderately, very, extremely).
Poor health was reported by 44 457 (27.3%) participants. The adjusted ORs for poor health were 3.86, 2.92, 2.60 and 6.41 for the highest, compared with lowest, deciles of Body Mass Index, waist circumference, waist to hip ratio and body fat percent, respectively. The associations were stronger in men (p<0.001). Overall, 7511 (4.6%) participants felt unhappy, and only class III obese participants were more likely to feel unhappy (adjusted OR 1.33, 95% CI 1.15 to 1.53, p<0.001) but the associations differed by sex (p<0.001). Among women, there was a significant association between unhappiness and all levels of obesity. By contrast, only class III obese men had significantly increased risk and overweight and class I obese men were less likely to be unhappy.
Obesity impacts adversely on happiness as well as health, but the association with unhappiness disappeared after adjustment for self-reported health, indicating this may be mediated by health. Compared with obese men, obese women are less likely to report poor health, but more likely to feel unhappy.
众所周知，肥胖会增加多种疾病的风险并降低总体生活质量。本研究探讨肥胖与自我报告健康状况（SRH）及幸福感之间的关系。
我们对163066名完成幸福感评分的英国生物银行参与者进行了一项横断面研究。使用逻辑回归分析肥胖与SRH及幸福感之间的关联。SRH被定义为良好（优秀、良好）或较差（中等、差）。自我报告的幸福感被定义为幸福（极其、非常、适度）或不幸福（适度、非常、极其）。
44457名（27.3%）参与者报告健康状况较差。与体重指数、腰围、腰臀比和体脂百分比的最低十分位数相比，最高十分位数的参与者健康状况较差的调整优势比分别为3.86、2.92、2.60和6.41。这些关联在男性中更强（p<0.001）。总体而言，7511名（4.6%）参与者感到不幸福，只有III级肥胖参与者更有可能感到不幸福（调整优势比1.33，95%置信区间1.15至1.53，p<0.001），但这种关联因性别而异（p<0.001）。在女性中，不幸福与所有肥胖水平之间存在显著关联。相比之下，只有III级肥胖男性的风险显著增加，超重和I级肥胖男性不幸福的可能性较小。
肥胖对幸福感和健康都有不利影响，但在调整自我报告的健康状况后，与不幸福的关联消失，这表明这可能由健康状况介导。与肥胖男性相比，肥胖女性报告健康状况较差的可能性较小，但感到不幸福的可能性更大。
