[Use of health services in Brazil: association with overweight and body fat indicators].

Abstract

The aim of the study was to analyze the association between use of health services and obesity in Brazilian adults. We carried out a population-based cross-sectional study in 100 districts of five Brazilian regions. The outcomes were: home care, use of medical services in the primary health care, use of medical services outside of the primary health care, use of emergency services and hospitalization. Excess weight was assessed by measurement of BMI and waist circumference (WC). Among the 8,603 subjects studied, the medical care in the primary health care was 14% and 18% higher among obese and high risk of WC, respectively, after controlled for socio-demographic variables and physical inactivity, but lost significance when adjusted for hypertension and diabetes. For the emergency services, both exposures resulted in increase of nearly 20% in the use of this service, after adjustments. The excess weight increased the use of medical services in the primary health care and emergency services.
