Data from: Age and gender differential relationship between employment status and body mass index among middle aged and elderly adults: a cross-sectional study

Objective: To determine the influence of age and gender respectively on the association between employment status and body mass index (BMI) in Korean adults using a large, nationally representative sample. Design: Cross-sectional study. Setting: South Korea. Participants: 7,228 from fourth wave of the Korean Longitudinal Study of Aging (KLoSA), the survey short form and year: “KLoSA 2012”. Main outcome measures: body mass index. Results: BMI among the employed was higher than among the unemployed for those under 60. In terms of gender, employed males reported higher BMI than their unemployed counterparts, whereas employed females reported lower BMI than did unemployed females. Conclusions: Employment status showed varying impacts on obesity by age and gender. Both unemployment at or after 60, as well as unemployment among females, is associated with increased BMI compared with unemployment among younger individuals or males, respectively.

研究目标：借助大型全国代表性样本，探究年龄与性别分别对韩国成年人就业状态与体质量指数（Body Mass Index, BMI）之间关联的影响。
研究设计：横断面研究。
研究地点：韩国。
研究对象：纳入韩国老龄化纵向研究（Korean Longitudinal Study of Aging, KLoSA）第四轮调查的7228名受试者，调查简况及年份标注为"KLoSA 2012"。
主要结局指标：体质量指数（BMI）。
研究结果：60岁以下人群中，就业者的体质量指数高于失业者；按性别分层分析显示，男性就业者的体质量指数高于同群体失业者，而女性就业者的体质量指数则低于同群体失业者。
研究结论：就业状态对肥胖的影响因年龄与性别而异。与年轻失业个体或男性失业者相比，60岁及以上失业人群以及女性失业人群的体质量指数均更高。
