[Prevalence of depressive symptoms and diagnosed depression among adults in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)].

In the German Health Interview and Examination Survey (DEGS1), current depressive symptoms were assessed with the "Patient Health Questionnaire" (PHQ-9) in a representative population-based sample of 7,988 adults 18-79 years old. In addition, previously diagnosed depression was assessed by physician interview. The prevalence of current depressive symptoms (PHQ-9 ≥ 10 points) is 8.1 % (women: 10.2 %; men: 6.1 %). For both sexes, the prevalence is highest among 18- to 29-year-olds and decreases with age. Persons with higher socioeconomic status (SES) are less likely to have current depressive symptoms. The lifetime prevalence of diagnosed depression is 11.6 % (women: 15.4 %; men: 7.8 %) and is highest among persons 60-69 years old. The 12 month prevalence is 6.0 % (women: 8.1 %; men: 3.8 %) and is highest among 50- to 59-year-olds. In women, but not in men, prevalences decrease with increasing SES. The results describe the distribution of two important aspects of depression among the adult population in Germany and confirm previously observed associations with age, gender and SES.
