In this context, Chronic Non-communicable Diseases (NCDs) point out as the main causes of limitations, disabilities and morbimortality. Measuring of lifestyle-related modifiable risk factors for NCDs is an indispensable premise for meeting this emerging demand through effective public policy. The objectives of this study were: (1) to identify multidimensional profiles of lifestyle-related risk factors, describing the prevalence of the sociodemographic and self-perceived health profiles and their characteristics; (2) to estimate life expectancy free from lifestyle-related risk factors in the Brazilian population. This study based on data from the National Health Survey (Pesquisa Nacional de Saude, PNS) published in 2013. Grade of Membership (GoM) method was used to identify lifestyle profiles, with data from 45,881 individuals over 30 years by applying the inclusion of 12 lifestyle-related variables. The analysis of the characteristics associated with these profiles was done through Pearson's chi-square test and unconditional logistic regression. The prevalence of the healthy profile and the Brazilian population's life table for 2013 were used in the Sullivan's method to calculate life expectancy free of lifestyle-related risk factors. In this stage, individuals aged between 30 and 69 years were selected, totalling 40,942. Two profiles were identified: a profile called “healthy profile” (61.6%; 95% CI 61.1 - 62.2), characterized by adequate consumption of fruits and vegetables, fish, and non-regular consumption of soda, meat with fat and beans. The profile was also characterized by overweight and for meeting the recommendations for physical activity at leisure time. The second profile was entitled “risk profile” (38.4%; 95% CI 37.8 - 38.9), characterized by non-consumption of healthy markers, except bean consumption, by the consumption of all unhealthy markers of eating, replacing meals with snacks, alcohol consumption and tobacco use. The second profile was also characterized for not being physically active at leisure and for being eutrophic. The healthy profile was associated with females, elderlies, white populations, residents of the North and Northeast regions of Brazil, widowed, married, high-educated populations and individuals who evaluate their health habits positively. The risk profile was associated with males, young adults, residents of the Midwest and South regions of Brazil, singles, less educated populations and individuals who evaluate their health habits negatively. The estimated lifetime for Brazilians free of lifestylerelated risk factors at age 30 was 33.5 years for women and 25.5 years for men. Females had a higher life expectancy free of risk factors at all ages in relation to males. The findings of the present study show the association of lifestyle-related risk factors with sociodemographic characteristics and contribute to the discussion of gender inequalities when it comes to morbimortality. Brazilian men live less time free of lifestyle-related risk factors, which may contribute to the high rates of premature mortality among them.Acesso AbertoExpectativa de vida saudávelEstilo de vidaDoença crônicaFatores de riscodoctoralThesisCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA
