Objective: The aim of this study was to examine the effects of depressive complaints and chronic medical illnesses on prospective somatic health care utilization and the possible heterogeneity of the effect of depressive complaints across levels of medical illness severity. Methods: Data from a community-based sample of adults (n=9428) were used, of whom a health survey and claims data, indicating health care use, were available. Assessments of depressive complaints and somatic illnesses were based on self-report. Binomial regression analyses were used to study the expected relations. Results: Depressive complaints and somatic morbidity were both positively related to general health care utilization. Somatic morbidity has an attenuating effect on the impact of depressive complaints: If it becomes more severe, the impact of depressive complaints on utilization is reduced. Depressive complaints are especially related to the use of paramedic services, use of prescription drugs, and consultations of medical specialists. Conclusion: Depressive complaints predict somatic health care utilization, but somatic morbidity attenuates this relation. Future research on this subject should include interaction effects of depressive complaints and somatic morbidity. Interventions aiming to reduce excess use related to mental distress should be primarily targeted on subjects with mental distress who have no comorbid somatic morbidity.
