There is a lack of studies that focus explicitly on the association between social exclusion and obesity. The aim of the present study was to identify whether social exclusion is associated with obesity in older adults, and whether this association is moderated by sex.
Data were derived from wave 5 (2014) of the German Ageing Survey - a representative sample of individuals residing in private households aged 40 and over in Germany. A validated scale developed by Bude and Lantermann was used to assess social exclusion. Individuals with body-mass-index ≥30 kg/m were classified as being obese. Multiple linear regressions were applied in this study.
Linear regressions showed that social exclusion was not associated with obesity in the total sample and in men, whereas women with obesity were less socially excluded than women without obesity (β = -.06, p = .02). The corresponding interaction term (sex x obesity) achieved statistical significance (p = .03).
Our findings emphasize the negative association between social exclusion and obesity in women, but not men, highlighting the complex interplay between social factors and excess weight in individuals aged 40 and above. Future longitudinal studies are needed to clarify this relationship in further detail.
目前缺乏专门研究社会排斥与肥胖之间关联的研究。本研究旨在确定社会排斥是否与老年人肥胖有关，以及这种关联是否受性别影响。
本研究的数据来自德国老龄化调查第五波（2014 年），这是一项代表德国居住在私人住宅中 40 岁及以上人群的代表性样本。采用 Bude 和 Lantermann 开发的经过验证的量表来评估社会排斥。身体质量指数（BMI）≥30 kg/m²的个体被归类为肥胖。本研究采用了多元线性回归。
线性回归显示，在总样本和男性中，社会排斥与肥胖无关，而肥胖的女性比非肥胖的女性受到的社会排斥程度较低（β=-0.06，p=0.02）。相应的交互项（性别 x 肥胖）具有统计学意义（p=0.03）。
我们的研究结果强调了社会排斥与女性肥胖之间的负相关关系，但与男性无关，这突显了社会因素与 40 岁及以上个体超重之间的复杂相互作用。需要进一步的前瞻性纵向研究来详细阐明这种关系。
