Sex Differences and Trends in Prevalence of Anxiety, Depression and Vital Exhaustion in Russia / Siberia from 1994 To 2017

Purpose: To determine gender differences in trends of anxiety, depression and vital exhaustion levels in an open population aged 25-64 years over long-term period - 23 years in Russia / Siberia (Novosibirsk). Methods: Within the framework of the screening in 1994-95 under the WHO MONICA-psychosocial (MOPSY) program (n = 1527, 43% males, mean age 44.85 ± 0.4 years), in 2003-2005 under the international project HAPIEE (n=1650, 34,9% males, mean age 54,25±0,2 years), in 2013-2016 (n=975, 43,8% males, mean age 34,5±0,4 years) and 2016-2017 гг.( n=663, 41,3% years 51,95±0,32 years) within the framework of the budgetary theme No. АААА-А17-117112850280-2, random representative samples of men and women in one of districts in Novosibirsk were examined. Anxiety traits studied by means of the Spielberger test. Depression and vital exhaustion assessed by MOPSY questionnaires. Results: 2/3 of the female population aged 25-64 years had high level of anxiety traits in 1994. It was highest in the younger age groups. High anxiety was found in less than half of the surveyed men, increasing with age. The maximum values of anxiety were noted in 2003-2005 in both genders. The decrease in the incidence of high anxiety which began in 2013-2016, remained only in the female part of the population aged 35-64y but in men the prevalence of anxiety returned to the levels of 1994. Depression occurred in more than half of the female population in 1994. The overall prevalence among men was less than 30%. At the same time, the frequency of major D in women was 4-fold higher compared with men (p <0.001). Trends in prevalence in 2017 were mixed: a reduction in moderate levels and an increase in major depression in the youngest and oldest age groups. The prevalence of high vital exhaustion in 1994 was 14.6% and 31% in men and women 25-64 years, respectively (p <0.001). An increase in high exhaustion from younger to older age groups was noted in both sexes. The downward trend in exhaustion in 2017 persisted only among women. At that moment for the first time men began to report high exhaustion more often than women over 23-year of follow-up (16.9% and 15.6% for men and women 35-64y, respectively; n.s.). Conclusion: The prevalence of affective states is higher in females in general population. Long-term trends in decreasing the prevalence of anxiety, depression and vital exhaustion were not sustainable and returned to levels of 1994.
