Longitudinal association between having stress-coping strategy and hypertension in a community-based Japanese study: the Circulatory Risk in Communities Study (CIRCS)
摘要
Aim: Hypertension is a leading contributor to the global disease burden and mortality. Although various risk factors have been identified, the roles of psychosocial stress and stress-coping strategies in the development of hypertension remain unclear. This study examined the longitudinal association between having a stress-coping strategy and the incidence of hypertension in Japanese communities. Methods: A prospective cohort study, a part of the Circulatory Risk in Communities Study, included 3668 participants (1359 men and 2309 women), aged 40–74 years, from three rural areas in Japan. Stress levels, the presence of a stress-coping strategy, and hypertension status were assessed annually from 2010 to 2018. Generalized linear mixed models were used to examine longitudinal associations of stress levels and stress-coping strategies with the incidence of hypertension, adjusting for potential confounding factors. Separate models were fitted to explore sex-specific associations. Results: The presence of a stress-coping strategy was significantly associated with a lower incidence of hypertension at baseline in both women (OR = 0.21 and 95% confidence interval (CI): 0.11 to 0.38, p < 0.001) and men (OR = 0.33, 95% CI: 0.18 to 0.60, p < 0.001). This association persisted throughout the follow-up period for both sexes, although the association was not significant in men with high stress. Conclusions: Having a stress-coping strategy was associated with a lower incidence of hypertension in both sexes. These findings highlight the potential role of coping strategies in hypertension prevention.
