Depressive disorder is one of the most common mental disorders in primary care. Depression is often a chronic disorder with recurrent episodes. Little is known about the differences in clinical profile between first and recurrent episodes. The aim of the study is to analyze the differences between clinical presentation of first and subsequent episodes of depressive disorders in primary care patients.A cross-sectional epidemiologic study in primary care centers in Spain was designed. A total of 10,257 primary care patients having a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition major depressive episode were analyzed. Clinical symptoms were measured using the Montgomery Asberg Depression Scale. Patient Health Questionnaire was used to assess somatic symptoms.There were 40.6% of patients who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for recurrent depression. Compared with those diagnosed of their first major depressive disorder, recurrent patients had greater rates and severity of depressive (t = -7.85, P < .001) and somatic symptoms (t = 5.64, P < .001). The severity of symptoms also increases with number of episodes (F = 40.2, P < .001, for depressive symptoms; F = 27.8, P < .001, for somatic symptoms). First-episode patients were more likely to experience reduced appetite (adjusted odds ratio, 1.2) and suicidal thoughts (adjusted odds ratio, 1.2).There are differences in the clinical profile of initial and recurrent episodes in primary care depressive patients. Each recurrent depressive episode seems to have a greater impact on symptoms and well-being. The identification of a specific depression symptom profile in first or recurrent episodes is needed to improve the long-term management of major depressive episode patients in primary care settings.
