THE ASSOCIATION BETWEEN SELF-REPORTED SLEEP DISORDERS AND EMOTIONAL COMPLAINTS: THE RESULTS OF THE SCREENING STUDY IN ADULT ST PETERSBURG CITIZENS

Objective. To assess the prevalence of self-reported sleep disorders and their association with emotional complaints in a representative sample of St Petersburg citizens.

Design and methods. Altogether 354 subjects were included (134 males, 220 females, age 25–65 years old). The survey included questions on sleep duration, sleep latency, frequency of sleep-associated complaints, daytime sleepiness; sleeping pills intake; anxiety and depression complaints (emotional tension and low mood).

 Results. According to the survey results 13,5 % respondents deny emotional strain, 65,4 % indicate occasional emotional tension, 21,1 % — complain of regular emotional tension. In older people there is a tighter relation between emotional complaints and early awakening and bruxism. In elderly subjects all sleep-related complaints are associated with emotional discomfort, and the most frequent are diffi culties at falling asleep. Both emotional strain (24,8 % women vs. 13,2 % men complain of regular emotional tension; p < 0,05) and depressed mood (13,2 % females vs. 2,4 % males indicate regular low mood; p < 0,001) were more prevalent in women.

Conclusion. Sleep disorders are associated with emotional discomfort (both tension and depressed mood), and fatigue, frequent early awakenings and nightmares are the most signifi cant. In elderly people emotional complaints are associated with a wider variety of sleep disorders that may be due to the common factor for both tension and depression complaints, and the age-related (organic, dyscirculatory) changes may be the underlying mechanism.
