ABSTRACT

Purpose@#The purpose of this study was to identify the associations between type of moderate-vigorous physical activities (MVPA) and psychological stress in South Korean, based on the Korean Genome and Epidemiology Study. The subjects of this study were 2,891 Korean men and women aged 40 to 69, who completed health examination from 2011 to 2012. @*Methods@#The type of MVPA was measured by using self-reported physical activity questionnaire. A high psychological stress was determined by scoring Psychological Well-being Index Short Form (≥ 27). Logistic regression analysis, adjusting other confounding factors, was conducted to identify the association of type of MVPA level with psychological stress (p＜ 0.05). @*Results@#Participants who leisure-related MVPA of ≥ 150 min/week was less likely have to high psychological stress than ＜ 150 min/week (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.57–0.92). From the analysis of gender, leisure-related (OR, 0.50; 95% CI, 0.35–0.72) and work-related (OR, 0.63; 95% CI, 0.41–0.97) MVPA of ≥ 150min/week were associated with low psychological stress in men, but women was not significantly associated. From the analysis of age, leisure-related MVPA of ≥ 150 min/week were associated with low psychological stress in middle age group (OR, 0.70; 95% CI, 0.53–0.92), but elderly group was not significantly associated. Differences inpsychological stress OR according to type of MVPA time were observed about classification of occupations. @*Conclusion@#High level of leisure related physical activity were independently associated with reducing risk for psychological stress. Also, encouraged MVPA by gender, age, classification of occupations could help to improve psychological stress levels in middle-aged or older adults.
