Summary:Abstract Funding Acknowledgements Type of funding sources: None. Introduction. According to the results of the recent studies, high levels of perceived stress were the potent risk factors for all-cause and cardiovascular mortality among the middle-aged population. However, there were few studies on the impact of this factor to mortality among the older males and females. Purpose. To investigate the association between perceived stress and all-cause and CVD mortality among the population of 75 years and older. Methods. This study was a part of the prospective cohort survey "Stress, aging and health." Data of 455 adults 75 years and older (287 males and 168 females) was used. We evaluated perceived stress Cohen"s Stress Scale. All items were scored on a 5-point scale, high scores indicated high levels of stress. Perceived Stress Scale sum scores were categorized into quintiles; we considered scores in the highest quintile (>19) as abnormal. The mean follow-up was 12 years, 292 deaths occurred, including 200 from cardiovascular diseases (CVD). Association between perceived stress and all-cause and CVD mortality was evaluated by Cox regression model after adjustment for age. Results. High levels of stress were significantly associated with all-cause and CVD mortality among elderly males (HR = 1,48 95% CI: 1,09-1,99; p = 0,01; HR = 1,65; 95% CI: 1,15-2,36; p = 0,007) after adjusting for age. At the same time, among females aged 75 years and older no significant associations of perceived stress scale high scores with all-cause and CVD mortality were found (HR = 1,28; 95% CI: 0,84-1,96; p = 0,25; HR = 1,19; 95% CI: 0,73-1,95; p = 0,48). Conclusions. Perceived stress contributed significantly to higher mortality rates among males aged 75 years and older. While among females of the same age, no significant associations between high stress levels and all-cause and CVD mortality were found.
