Methods The study included 2,201 primary care users in the city of Porto Alegre, Brazil. The participants' physical and emotional health was assessed through an interview using a questionnaire including 2 general questions from the World Health Organization's Quality of Life instrument (WHOQOL - brief); other questions from the Medical Outcomes Study Short-Form 12 (SF-12), MHI5 (MHI-5), Centers for Epidemiologic Studies - Depression (CES-D), and additional questions about work loss days and health care utilization. Results Of all individuals, 79.5% were women aged on average 40 years. The intensity of depressive symptoms (measured by CES-D) was 20.2 for women and 162 for men.
