Background: Chronic obstructive pulmonary disease (COPD) is a major public health problem with increasing mortality worldwide. Obesity is well known to be associated with increased morbidity and mortality in the general population but in the case of COPD, a phenomenon known as the “obesity paradox” is observed. Nutritional status is a good prognostic indicator in patients with COPD.
Methods: A cross-sectional study was conducted in a tertiary care hospital of Lucknow with 250 COPD patients to assess their body mass index (BMI) using Quetelet’s formula. Study subjects were selected using a systematic random sampling method.
Results: The mean BMI was observed to be 24.93±4.0. Health-related quality of life of undernourished patients was most affected. A statistically significant relation was seen across all the components of SGRQ.
Conclusions: The results of the study indicated that the malnourished COPD patients had poor health-related quality of life and severe limitation in airflow.
