Abstract:
: This cross-sectional study investigated the association between long working hours and prevalence of poor self-rated health (SRH) in Korean young workers using data from the 6th Korea Youth Panel Survey 2007. A total of 3317 young wage workers were included. Weekly working hours were divided into four groups (36 to 40 hours, 41 to 52 hours, 53 to 60 hours, and more than 60 hours per week). Multiple logistic regression was performed to investigate the association between long working hours and SRH, adjusting for demographic and work-related factors. Long working hours were associated with increased risk of poor SRH, in both the men and women. Legal restriction on working hours should be suitably applied to help improve the health status of Korean young workers.
