Risk and protective behaviors for chronic non-communicable diseases among Brazilian adults

This study aimed to analyze behavioral patterns of protective and risk factors for chronic non-communicable diseases (NCDs) among adults and to explore the association between these patterns and sociodemographic characteristics using data from the National Health Survey 2013.

This was a cross-sectional study.

This is a population-based study, nationwide, of individuals aged ≥18 years (n = 60,202). The sampling process used was grouping with three selection stages: census sector, households, and individuals. The factor analysis by principal component was used to identify behavioral patterns of protective and risk factors for NCDs. Linear regression was used to explore the association between patterns and sociodemographic characteristics.

Two behavioral patterns were identified: a 'protective pattern' featured by consumption of vegetable, fruits/natural fruit juice, and low-fat milk and recommended physical activity practice during leisure time; and a 'risk pattern' characterized by consumption of high-fat meat and soft drinks, alcohol abuse, and smoking habit. Adherence to the protective pattern was associated with older White women who had higher levels of education, were economically active, and lived in the urban areas of the country. Younger, economically active men living in the urban areas were associated with the risk patterns.

Two behavioral patterns for NCDs have been identified and are distributed non-randomly in the adult Brazilian population. These findings are expected to contribute to better targeting health promotion and prevention of NCDs.
