The aim of the study was to investigate depressive mood in association with sociodemographic, behavioral, self-perceived health, and coronary artery disease (CAD) risk factors and sleep complaints among 35-74-year-old citizens of Palanga. MATERIAL AND METHODS. A representative sample of randomly selected 1602 persons, 600 men and 1002 women, was studied. Depressive mood was assessed by the WHO-5 Well-being Index. Sleep complaints, self-perceived health, and behavioral factors were evaluated by the Basic Nordic Sleep Quality questionnaire and questionnaires on self-perceived health and health behavior. Risk factors for CAD were assessed according to WHO recommendations. RESULTS. The highest prevalence of depressive mood (34.7%) was identified in the age group of 45-54 years in the men and in the age group of 55-64 years in the women (30.0%). The highest odds ratios demonstrating a strong association between depressive mood and health behavior were established for the use of antidepressants (OR=26.0) in the men and for the use of sedatives (OR=3.09) in the women. The highest odds ratios demonstrating an association between depressive mood and self-perceived health were established for chronic pyelonephritis (OR=3.13) in the men and diabetic foot pain (OR=4.46) in the women. The highest odds ratios reflecting an association between depressive mood and sleep quality were established for the inability to work due to disturbed sleep (OR=1.93) in the men and self-perceived sleep quality (OR=1.55) in the women. CONCLUSIONS. Depressive mood, which was significantly associated with risky health behavior, poor self-perceived health, and disturbed sleep, was observed more often in the women than the men; however, significant associations between depressive mood and risk factors for CAD were not established.
