Cad. Saúde Pública [online]. 2011, vol.27, n.6, pp. 1121-1131. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2011000600009.
The objective of this study was to assess the quality of life in the Brazilian adult population, based on the U.S. standard population. It involved a cross-sectional population-based study with probabilistic sampling of 2,420 individuals (725 men and 1695 women) aged 40 or more in different geographic regions of Brazil. A socio-demographic questionnaire and the SF-8 (Short Form-8) were administered in interview form. Descriptive statistics, analysis of variance, the Mann-Whitney test and Tukey's test were used in the analysis. Females, populations in the northeastern region, the population of the regions of Brasília (Distrito Federal), Campo Grande (Mato Grosso do Sul State) and Goiania (Goiás State), Brazil, demonstrated worse quality of life. Age, education and income had influence over quality of life domains. This study presents quality of life estimates for the Brazilian adult population, based on the SF-8 questionnaire. The mean values on the subscales and components of the SF-8 appeared to be influenced by gender, geographic region, family income, age and schooling.
