Prevalência de sintomáticos respiratórios em regi？es do Distrito Federal, Brasil

the identification of individuals with respiratory symptoms (rs) is important for the early detection of tuberculosis. the aim of this study was to estimate the prevalence of rs in three administrative regions of the federal district, brazil. for this, we used the 30 by 7 cluster sampling technique proposed by the world health organization. individuals with rs were defined as those aged 15 years or older living in the administrative regions of estrutural, itapo？, or varj？o and reporting a cough lasting at least 3 weeks at the date of the interview. the prevalence of rs was 5.7% in estrutural and varj？o (95% ci: 2.4-9.0) and 4.8% in itapo？ (95%ci: 1.6-7.9), with a design effect close to 1.0. in estrutural and itapo？, fewer years of schooling, and in itapo？ and varj？o, lower income, were associated with rs. cigarette smoking was associated with the presence of rs in all regions. the prevalence of rs in the three administrative regions investigated is consistent with that of other areas with a similar socioeconomic profile.
