title: Relationship among lifestyles, aging and psychological wellbeing using the General Health Questionnaire 12-items in Japanese working men.
abstract: INTRODUCTION. The relationship among lifestyle, aging and psychological wellbeing was evaluated in Japanese working men. METHODS. Self-administered questionnaire on six lifestyle factors and the General Health Questionnaire 12-item version (GHQ12) were administered to 3306 male workers. Health practice index (HPI) was calculated as a desirable lifestyle score by summing up each binary lifestyle score (0, 1), ranging from 0 to 6. To check validity of the study outcome, the authors repeated twice with 1 year interval. HPI was categorised into three groups by the score of 0-2, 3-4 and 5-6. RESULTS. The number of subjects categorised by HPI was 532, 1967 and 807, respectively. The mean value of GHQ12 significantly decreased as the HPI increased by adjusting age. Multiple regression analysis was conducted to predict GHQ12 by six lifestyle scores, and age, sleep, night snacking and exercise were significantly related to GHQ12. Multiple logistic regression analysis was conducted and age in 50s, two-shift work, sleep, night snacking and exercise were significantly associated with GHQ12. CONCLUSION. Although cause-effect relationship cannot make clear, some of desirable health practices and aging were closely related to psychological wellbeing judged by GHQ12.
