Background & objectives : Chronic obstructive pulmonary disease (COPD) is a major public health problem in India. Its magnitude is particularly high among the elderly. Old age and comorbidity may lead to misdiagnosis and under treatment of this condition. COPD is not curable; however, various forms of treatment can help control symptoms and improve the quality of life. Most of the earlier studies lacked uniformity in definitions, designs, methodology and reporting techniques. Studies based on spirometry are only a few. Understanding the current prevalence and associated factors of COPD is important for planning control strategies. Hence, this study was conducted to determine the prevalence of COPD and associated factors among the elderly. Methods : In this community-based study among 449 elderly persons in a rural area, information regarding socio-demographic details, selected health conditions and exposure to risk factors was recorded. The assessment of airway obstruction was done by using a portable spirometer (MIR Spirolab). The diagnosis of COPD was based on the GOLD criteria. The association of COPD with sociodemographic and other variables was analysed by the multivariate logistic regression. Results : Acceptable spirometry findings were available for 392 (87.3%) participants. The prevalence of COPD was 42.9 per cent (95% confidence interval 37.9-47.7%). The prevalence was 54.5 per cent among men and 33.4 per cent among women. Smoking, higher age group and low body mass index were significantly associated with COPD. Interpretation & conclusions : The prevalence of COPD was found to be high among the rural elderly in this study. Interventions aimed at cessation of smoking and preparedness of health systems for diagnosis and management of COPD are hence required.
