Abstract: Despite its high disease burden, few existing estimates of the prevalence of obstructive lung disease in India are based on high-quality data sources. To our knowledge, prior studies at the national level have not included objective measurements of lung function. The Longitudinal Aging Study in India administered spirometry to adults 45 years and older (N = 31,103). We estimated inverse probability weights to account for sample selection processes and quantified the prevalence of obstructive lung disease overall and by region, age, and gender. We investigated the overlap among objective rates of obstructive lung disease, respiratory symptoms, and self-reported diagnoses. Additionally, we evaluated associations between obstructive lung disease and pertinent risk factors. The overall prevalence of obstructive lung disease was 14.4% (95% confidence interval [CI] 13.4–15.4). Prevalence was higher among men than women (p
