Previous studies have extensively examined the relationship between body mass index (BMI) and subjective well-being (SWB) but have mainly focused on the effects of BMI on SWB, leaving the question of whether BMI can be influenced by SWB largely neglected. In this study, we present the first empirical evidence on the effects of SWB on BMI among adults, using data combined from four waves of the Chinese General Social Survey (CGSS) (2010-2013). We find that, among urban Chinese adults, those who have a higher level of happiness tend to have higher BMI, after extensively controlling for a constellation of individual sociodemographic and health attributes. Further analyses using the instrumental variable method and propensity score matching provided similar results.
先前的研究广泛考察了体重指数（BMI）与主观幸福感（SWB）之间的关系，但主要关注 BMI 对 SWB 的影响，而很大程度上忽略了 BMI 是否会受到 SWB 的影响。在这项研究中，我们利用中国综合社会调查（CGSS）（2010-2013 年）的四轮数据，首次提供了有关成年人 SWB 对 BMI 影响的实证证据。我们发现，在中国城市成年人中，在广泛控制了一系列个体社会人口学和健康特征后，那些幸福感较高的人往往 BMI 也较高。使用工具变量法和倾向得分匹配进行的进一步分析得出了类似的结果。
