Abstract: OBJECTIVES: This study examined the independent and interactive effects of chronic medical conditions and sleep disturbance on depressive symptomatology. The sample (N = 675) consisted of community-dwelling Korean American older adults, a group that has been found to be particularly high in depressive symptomatology. METHODS: A hierarchical regression model of depressive symptoms was estimated with an array of predictors: (a) demographic variables, including immigration history, (b) chronic medical conditions, (c) sleep disturbance, and (d) an interaction between chronic medical conditions and sleep disturbance. RESULTS: After controlling for the effects of demographic variables, both chronic medical conditions and sleep disturbance were identified as independent risk factors for depressive symptoms. Moreover, their interaction was significant, indicating that the coexistence of chronic medical conditions and sleep disturbance was significantly associated with higher levels of depressive symptoms (β = 0.15, p < 0.01). CONCLUSION: Our findings call attention to sleep hygiene among older individuals with chronic medical conditions and recommend that sleep quality should be closely monitored and assessed by healthcare professionals.
