The costs of overweight and obesity-related diseases in the Brazilian public health system: cross-sectional study

Abstract

Abstract Background Obesity is a major global epidemic and a burden to society and health systems. It is well known risk factor for a number of chronic medical conditions with high morbidity and mortality. This study aimed to provide an estimate of the direct costs associated to outpatient and inpatient care of overweight and obesity related diseases in the perspective of the Brazilian Health System (SUS). Methods Population attributable risk (PAR) was calculated for selected diseases related to overweight and obesity and with the following parameters: Relative risk (RR) ≥ 1.20 or RR ≥1.10 and Results The estimated total costs in one year with all diseases related to overweight and obesity are US$ 2,1 billion; US$ 1,4 billion (68.4% of total costs) due to hospitalizations and US$ 679 million due to ambulatory procedures. Approximately 10% of these cost is attributable to overweight and obesity. Conclusion The results confirm that overweight and obesity carry a great economic burden for Brazilian health system and for the society. The knowledge of these costs will be useful for future economic analysis of preventive and treatment interventions.
