Smoking trend indicators in Brazilian capitals, 2006-2013

This study aims to analyze the trend of indicators related to smoking in the capitals of Brazil from 2006 to 2013. Information on smoking trends extracted from the survey of risk and protective factors for chronic non-communicable diseases (NCDs) are analyzed through telephone interviews - VIGITEL conducted from 2006-2013 for the adult population in Brazilian capitals. To estimate the trend, the simple linear regression model was used. The prevalence of smokers in Brazil showed a relative reduction of 0.62% for each year of the survey, ranging from 15.6% in 2006 to 11.3% in 2013. A decrease was observed in both sexes in all age ranges except between 55 and 64 years in all education levels and regions. The total population of former smokers remained stable, with a reduction for men. Smoking 20 or more cigarettes per day decreased from 4.6% (2006) to 3.4% (2013), or 0.162 percentage points per year. Passive smoking at home decreased among women 13.4% (2009) to 10.7% (2013), a reduction of 0.72% per annum. Passive smoking at work has remained stable over the period. The smoking trend reduced in the period in most indicators, reflecting the importance of the tobacco control actions in the country.
