Proportion of Vitamin D Deficiency among Chronic Obstructive Pulmonary Disease Patients and Its Correlation with Lung Function – A Cross-sectional Study
Abstract
Background: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Vitamin D deficiency has been implicated in immune dysregulation and may influence disease severity and exacerbation risk in COPD. This study aimed to estimate the prevalence of Vitamin D deficiency among COPD patients and assess its correlation with lung function. Methods: This cross-sectional study was conducted among 82 COPD patients aged >40 years diagnosed by spirometry (forced expiratory volume in 1 s [FEV1]/Forced Vital Capacity [FVC]
