[Costs attributable to obesity, hypertension, and diabetes in the Unified Health System, Brazil, 2018Costos atribuibles a la obesidad, la hipertensión y la diabetes en el Sistema Único de Salud de Brasil, 2018]. / Custos atribuíveis a obesidade, hipertensão e diabetes no Sistema Único de Saúde, Brasil, 2018.

OBJECTIVE: To estimate the cost attributable to arterial hypertension, diabetes and obesity in the Unified Health System of Brazil in 2018. METHOD: The study estimated the cost attributable to non-communicable chronic diseases based on relative risk and population prevalence of hypertension, diabetes, and obesity, considering the cost of hospitalizations, outpatient procedures, and medications distributed by the SUS to treat these diseases. Cost data were obtained from SUS information systems. The analysis explored the cost of disease according to sex and age in the adult population. RESULTS: The total cost of hypertension, diabetes, and obesity in the SUS reached R$ 3.45 billion (95%CI: 3.15-3.75) in 2018, that is, more than US$ 890 million. Of this amount, 59% referred to the treatment of hypertension, 30% to diabetes, and 11% to obesity. The age group from 30 to 69 years accounted for 72% of the total costs, and women accounted for 56%. When obesity was considered separately as a risk factor for hypertension and diabetes, the cost attributable to this diseases reached R$ 1.42 billion (95%CI: 0.98-1.87), i.e., 41% of the total cost. CONCLUSIONS: The estimates of costs attributable to the main chronic diseases associated with inadequate diet revealed a heavy economic burden of these disorders for the SUS. The data show the need to prioritize integrated and intersectoral policies for the prevention and control of hypertension, diabetes, and obesity, and may support the advocacy for interventions such as fiscal and regulatory measures to ensure that the objectives of the United Nations Decade of Action on Nutrition are met.

OBJETIVO: Estimar los costos atribuibles a la hipertensión arterial, la diabetes y la obesidad en el Sistema Único de Salud (SUS) de Brasil en el 2018. MÉTODOS: Se estimaron los costos atribuibles a las enfermedades crónicas no transmisibles a partir de los riesgos relativos y de las tasas de prevalencia poblacional de hipertensión, diabetes y obesidad, teniendo en cuenta los costos de hospitalización, los procedimientos ambulatorios y los medicamentos distribuidos por el SUS para el tratamiento de esas enfermedades. Los datos de costos se obtuvieron en los sistemas de información de salud disponibles en el SUS. En el análisis se exploraron los costos de las enfermedades según el sexo y la edad de la población adulta. RESULTADOS: Los costos totales atribuibles a la hipertensión, la diabetes y la obesidad en el SUS alcanzaron R$ 3,450 milliones (IC 95%: de 3,15 a 3,75) en el 2018, o sea, más de US$ 890 millones. De esos costos, 59% correspondió al tratamiento de la hipertensión, 30% al de la diabetes y 11% al de la obesidad. En total, 72% de los costos correspondieron a personas de 30 a 69 años y 56%, a mujeres. Al considerarse por separado la obesidad como factor de riesgo de hipertensión y diabetes, los costos atribuibles a esa enfermedad alcanzaron R$ 1.420 millones (IC 95%: de 0,98 a 1,87), o sea, 41% del total. CONCLUSIONES: Las estimaciones de los costos atribuibles a las principales enfermedades crónicas relacionadas con la alimentación inadecuada ponen de manifiesto la pesada carga económica de esas enfermedades para el SUS. Los datos muestran la necesidad de priorizar políticas integradas e intersectoriales para la prevención y el control de la hipertensión, la diabetes y la obesidad, y permiten apoyar la defensa de intervenciones como medidas fiscales y regulatorias para alcanzar los objetivos del Decenio de las Naciones Unidas de Acción sobre la Nutrición.

Direct healthcare cost of obesity in brazil: an application of the cost-of-illness method from the perspective of the public health system in 2011.

BACKGROUND: Obesity is a global public health problem and a risk factor for several diseases that financially impact healthcare systems. OBJECTIVE: To estimate the direct costs attributable to obesity (body mass index {BMI} ≥ 30 kg/m2) and morbid obesity (BMI ≥ 40 kg/m2) in adults aged ≥ 20 incurred by the Brazilian public health system in 2011. SETTINGS: Public hospitals and outpatient care. METHODS: A cost-of-illness method was adopted using a top-down approach based on prevalence. The proportion of the cost of each obesity-associated comorbidity was calculated and obesity prevalence was used to calculate attributable risk. Direct healthcare cost data (inpatient care, bariatric surgery, outpatient care, medications and diagnostic procedures) were extracted from the Ministry of Health information systems, available on the web. RESULTS: Direct costs attributable to obesity totaled US$ 269.6 million (1.86% of all expenditures on medium- and high-complexity health care). The cost of morbid obesity accounted for 23.8% (US$ 64.2 million) of all obesity-related costs despite being 18 times less prevalent than obesity. Bariatric surgery costs in Brazil totaled US$ 17.4 million in 2011. The cost of morbid obesity in women was five times higher than it was in men. CONCLUSION: The cost of morbid obesity was found to be proportionally higher than the cost of obesity. If the current epidemic were not reversed, the prevalence of obesity in Brazil will increase gradually in the coming years, as well as its costs, having serious implications for the financial sustainability of the Brazilian public health system.
