Doença pulmonar obstrutiva crônica e fatores associados em São Paulo, SP, 2008-2009

Abstract

OBJECTIVE:To assess the prevalence of chronic obstructive pulmonary disease and related risk factors. METHODS:A population-based cross-sectional study with 1,441 individuals of both sexes aged 40 years or more was conducted in the city of São Paulo, Brazil, between 2008 and 2009. A two-stage (census tract, household) cluster random sampling stratifi ed by sex and age was used and data was collected through home interviews. Multiple Poisson regression was used in the adjusted analysis. RESULTS:Of all respondents, 4.2% (95%CI: 3.1;5.4) reported chronic obstructive pulmonary disease. After adjustment the following factors were found independently associated with self-reported chronic obstructive pulmonary disease: number of cigarettes smoked in their lifetime (>1,500 vs. none) (PR=3.85; 95%CI: 1.87;7.94); easily fatigued (yes vs. no) (PR=2.61; 95%CI: 1.39;4.90); age (60;69 vs. 50;59) (PR 3.27; 95%CI: 1.01;11.24); age (70 and over vs. 50;59) (PR 4.29; 95%CI: 1.30;11.29); health conditions in the last 15 days (yes vs. no) (PR=1.31; 95%CI: 1.02;1.77); leisure-time physical activity (yes vs. no) (PR=0.57; 95%CI: 0.26;0.97). CONCLUSIONS:The prevalence of chronic obstructive pulmonary disease is high in the population studied and is associated with smoking and age over 60. Frequent health conditions and low leisure-time physical activity are a consequence of the disease.

Prevalência de atividade física no lazer e fatores associados: estudo de base populacional em São Paulo, Brasil, 2008-2009

“…Além disso, doenças crônicas relacionadas ao coração e ao pulmão podem levar ao cansaço frequente, e em virtude dessa incapacidade e limitação para as atividades diárias provocadas pela doença, os indiví-duos podem permanecer em comportamentos sedentários na maior parte do dia para amenizar os sintomas. Essa preferência pelo repouso excessivo é explicada pela sensação de falta de ar e de esgotamento muscular precoce na presença de qualquer intensidade de atividade física 14,38 . Florindo et al 31 verificaram que reportar baixa condição de saúde esteve positivamente associado com o baixo nível de atividade física de lazer, assim como o hábito de fumar.…”

“…We also noted the presence of chronic sputum as a respiratory symptom as well as self-diagnosed asthma and the saturation presence of ≤ 90% for pulse oximetry at rest. The study which was conducted in São Paulo showed, after the analysis was adjusted, that the following factors independently were associated with COPD: smoking, becoming tired very easily, being over the age of 60, health problems in the last 15 days and a lack of physical activity in their free time 14 . However, the study that was referred to, covered self-diagnosed COPD which represents an important limitation for the condition which is not well known by the general population 5,15 .…”
