Abstract
To estimate the prevalence of self-reported osteoporosis (with previous medical diagnosis) and the associated risk and protection factors. A cross-sectional study was carried out, based on data from the system Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL--telephone-based surveillance of risk and protective factors for chronic diseases). A total of 54,369 individuals aged > or = 18 years living in homes served by at least one fixed telephone line in Brazilian state capitals and the Federal District in 2006 were interviewed. Estimates of osteoporosis in relation to socioeconomic and behavioral factors and the body mass index were stratified according to sex. The risk of occurrence of osteoporosis was calculated for each variable separately and through a multivariate model, taking the odds ratio to be a proxy for the prevalence ratio. The reported prevalence of osteoporosis was 4.4%, predominantly among women (7.0%) > or = 45 years of age whose marital status was not single and who were former smokers. Among men, age > 65 years, married or widowed status and sedentarism were positively associated with this outcome. Among the factors associated with osteoporosis, modifiable characteristics relating to disease prevention were highlighted, such as physical activity and smoking habits.
Highlights
The aging of the Brazilian population is reflected in the current total of more than 16 million individuals over the age of 60 years

The aim of the present study was to estimate the frequency of self-reported osteoporosis and associated factors. This was a cross-sectional study based on data from the system of telephone-based surveillance of risk and protective factors for chronic diseases (Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico, VIGITEL), in 2006
Summary
The aging of the Brazilian population is reflected in the current total of more than 16 million individuals over the age of 60 years. This number is projected to exceed 50 million in 2050.a the chances of occurrences of age-related diseases among the population, such as osteoporosis, are increasing. High body mass index (BMI ≥ 30 kg/m2) and daily physical activity lasting more than 30 minutes perform a protective role.b the prevalence of osteoporosis and factors associated with it among the Brazilian population have not been fully clarified
