Correlating nutritional status with severity of chronic obstructive pulmonary disease in adult females

Context: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Recent studies report increased the prevalence of COPD among adult females and nutrition is an important prognostic marker in COPD. Nutrition in Indian females is already a concern, further compromised by increasing the prevalence of COPD. Aims: A study correlation of six selected nutritional parameters: Body mass index, waist-hip ratio, waist-height ratio, serum albumin, hemoglobin, and Mini Nutritional Assessment (MNA) score with the severity of COPD (Global Initiative for Obstructive Lung Diseases [GOLD] categorization) in adult female patients. Settings and Design: A cross-sectional analytical study including all adult female patients diagnosed with COPD based on spirometry, attending pulmonary medicine outpatient department of a medical college between January and June 2014. Patients with pulmonary tuberculosis, acute exacerbations of COPD, and those unwilling to participate were excluded from the study. Subjects and Methods: A total of 100 patients were studied with a detailed history, physical examination, spirometry, anthropometric measurements, laboratory parameters of nutrition, and MNA questionnaire. Statistical Analysis Used: SPSS 14.01 version (IBM analytics) with Pearsonu0027s correlation coefficient and one-way analysis of variance (ANOVA) as tests of significance. Results: The study revealed that proportion of adult female COPD patients with GOLD categorization is 7% GOLD1, 40% GOLD 2, 42% GOLD 3, and 11% GOLD 4. Pearsonu0027s correlation coefficients calculated for the severity of COPD with six selected nutritional parameters showed statistically significant correlation with MNA score (correlation coefficient = −0.253, P F = 2.353, df = 3, P F = 2.582, df = 3, P Conclusions: The study concludes that malnutrition increases the severity of COPD. Further, it also concluded that MNA score and waist-height ratio correlate better with the severity of COPD than other nutritional parameters.
