The aim of this study was to estimate the risk of cardiovascular disease (CVD) caused by working hours in the South Korean working population stratified by sex and type of work.
We analyzed longitudinal data from the Korean Longitudinal Study of Aging in 2006. The risk of CVD associated with working hours was estimated using Cox regression analysis. In addition, the analysis was conducted by stratifying the sample by sex and type of work (wage work and self-employment).
After adjusting for all covariates, subjects in long working hours (≥50 h/wk) groups showed increased risk of CVD. After sex and type of work stratification, only women and wageworkers showed significantly increased risk of CVD associated with long working hours.
The results demonstrated that increased risk of CVD was associated with long working hours, especially in women and wageworkers.
本研究旨在估计按性别和工作类型分层的韩国劳动人口中工作时间与心血管疾病（CVD）风险之间的关系。
我们分析了 2006 年韩国老龄化纵向研究的纵向数据。使用 Cox 回归分析估计了与工作时间相关的 CVD 风险。此外，还按性别和工作类型（受薪工作和自营职业）对样本进行分层分析。
在调整所有协变量后，长时间工作（≥50 小时/周）组的受试者 CVD 发病风险增加。在按性别和工作类型分层后，只有女性和受薪工人的长时间工作与 CVD 发病风险显著相关。
研究结果表明，CVD 发病风险与长时间工作有关，尤其是在女性和受薪工人中。
