To explore the nutritional status of chronic obstructive pulmonary disease (COPD) patients in Hengshui area and to explore the influencing factors of malnutrition in COPD patients.

A total of 321 COPD patients in our hospital from January 2018 to October 2022 were selected, including 189 males and 132 females, aged 49 to 62 years, with an average age of(55.23 ±3.01) years. Patients were divided into normal nutrition group and malnutrition group. Univariate analysis was used to compare the demographic characteristics, clinical data, and laboratory examinations between the two groups. Logistic regression was used to analyze the possible influencing factors of malnutrition in COPD patients.

Logistic regression analysis showed that age (OR=2.496, 95%CI: 1.204-1.860), annual family income (OR=0.569, 95%CI: 0.386-0.839), COPD Assessment Test (CAT) score (OR=1.917, 95%CI: 1.288-2.854), 6-Minute Walk Test (6MWT) (OR=0.550, 95%CI: 0.350-0.865), modified Medical Research Council Dyspnea Scale (mMRC) score (OR=1.944, 95%CI: 1.076-3.515), number of acute exacerbations of COPD hospitalization (OR=1.788, 95%CI: 1.053-3.035), and sarcopenia (OR=2.782, 95%CI: 1.542-5.018) were independent influencing factors of malnutrition in patients with COPD in Hengshui area.

In total 47.35% of the 321 COPD patients in Hengshui area had malnutrition, and age, annual family income, CAT score, 6MWT, mMRC score, acute exacerbation of chronic obstructive pulmonary disease, and sarcopenia are the independent influencing factors of malnutrition in COPD patients. It is suggested to formulate feasible and targeted intervention measures according to the above factors in order to reduce the incidence of malnutrition in patients with COPD, reduce the clinical manifestations of sarcopenia, and prolong the survival time.
