Correlation of BMI and oxygen saturation in stable COPD in Northern India.

Background: Chronic obstructive pulmonary disease (COPD) is associated with clinically relevant extra pulmonary manifestations; one of them is weight loss. However, there are very few studies from North India available in relation to body mass index (BMI) and Oxygen saturation (SpO2) with COPD.

Aims: To study the prevalence of undernutrition among stable COPD patients and correlation of COPD severity with SpO2 and BMI.
