Obesity is a chronic disorder associated with high mortality rates and high morbidity. The risk of obesity is associated with certain personality traits (PTs). Some studies have found correlations among some PTs and gender. Additionally, obesity implies higher costs in daily living. The aim of this paper is to overcome this problem in the literature and estimate the association between PTs and obesity by taking into account the economic situation of the individual. This study employs data from the English Longitudinal Study of Ageing (ELSA). We focus on waves 5 and 6 of the ELSA with a sample of 6562 individuals. The results suggests that the traits of agreeableness ( $\beta =0.071,\mathit{se}=0.016,p<0.001$) and openness ( $\beta =0.028,\mathit{se}:0.014,p<0.001$) are positively and significantly associated with obesity. On the other hand, consciousness has a negative and statistically significant effect on obesity $\left(\beta =0.072,\mathit{se}:0.017,p<0.001\right)$. Results are robust to the inclusion/exclusion of different regressors.

英国老龄化纵向研究中人格特质、性别和社会经济因素对肥胖的影响

肥胖是一种与高死亡率和高发病率相关的慢性疾病。肥胖的风险与某些人格特质 (PT) 相关。一些研究发现某些 PT 与性别之间存在相关性。此外，肥胖意味着日常生活成本更高。本文的目的是克服文献中的这个问题，并通过考虑个人的经济状况来估计 PT 与肥胖之间的关联。本研究采用了英国老龄化纵向研究 (ELSA) 的数据。我们专注于 ELSA 的第 5 波和第 6 波，样本为 6562 人。结果表明，宜人性的特征（ $\beta =0.071,\mathit{硒}=0.016,p<0.001$) 和开放性 ( $\beta =0.028,\mathit{硒}:0.014,p<0.001$) 与肥胖呈正相关且显着相关。另一方面，意识对肥胖有负面的统计显着影响$\left(\beta =0.072,\mathit{硒}:0.017,p<0.001\right)$. 结果对于包含/排除不同的回归变量是稳健的。
