Key result
Between 2006 and 2012, the prevalence of diabetes (β=0.30, P=0.001), overweight (β=0.50, P=0.002), and obesity (β=0.88, P<0.001) increased in Brazil, while hypertension and alcohol abuse were stable.
Why the study?
Stroke is a leading cause of death worldwide and in Brazil, prompting an analysis of temporal trends in modifiable stroke risk factors from 2006 to 2012.
Observational
Between 2006 and 2012, the Brazilian population experienced a significant increase in the prevalence of diabetes, overweight, and obesity, highlighting a growing burden of metabolic risk factors for stroke.
Should not yet change stroke-prevention practice; leaves open whether later surveys confirm these Brazilian metabolic-risk trends.
Stroke is one of the leading causes of death worldwide, including in Brazil. This study aimed to analyze the temporal trend of the prevalence of modifiable risk factors of stroke from 2006 to 2012. This ecological study was conducted by secondary analysis in May 2018, using data from the surveillance of risk factors and protection for chronic diseases by telephone inquiry (VIGITEL) available in the Department of Informatics of the Unified Health System (DATASUS). The modifiable risk factors of stroke in Brazilians were systemic arterial hypertension, diabetes mellitus, abusive alcohol consumption, overweight, and obesity. Overall, there was a significant increase in the risk factors of diabetes (β = 0.30, P = 0.001, r2 = 0.99), overweight (β = 0.50, P = 0.002, r2 = 0.98), and obesity (β = 0.88, P < 0.001, r2 = 0.96). However, there was a stability in the prevalence of hypertension (β = 0.25, P = 0.320, r2 = 0.88) and alcohol abuse (β = 0.32, P = 0.116, r2 = 0.49). There was an increase in the prevalence of diabetes mellitus, overweight, and obesity, but stability in systemic arterial hypertension and abusive alcohol consumption in the Brazilian population.
