Factors Associated with Nutritional Risk in Patients with Pulmonary Tuberculosis and Structural Lung Disease: A Hospital-Based Cross-Sectional Study.

Abstract

ObjectivePatients with tuberculosis have a high nutritional risk, and patients with tuberculosis and structural lung disease have a poor quality of life. However, few studies have investigated the nutritional risk of patients with tuberculosis and structural lung disease. This study aimed to evaluate nutritional risk in patients with pulmonary tuberculosis and structural lung disease and to identify factors associated with nutritional risk in this population.MethodsWe performed a cross-sectional study of patients diagnosed with pulmonary tuberculosis and structural lung disease admitted to The Third People’s Hospital of Shenzhen, China between January 1, 2019 and December 31, 2021. We assessed participants’ nutritional risk using the Nutritional Risk Screening 2002 tool, and analyzed the relationship between nutritional risk and sociodemographic factors, disease status, and laboratory test results.ResultsOf the 415 participants, 53.5% were at nutritional risk on admission to the hospital. Nutritional risk was significantly associated with being unmarried, destroyed lung, and red blood cell (RBC) and lymphocyte counts.ConclusionPatients with tuberculosis and structural lung disease had a high prevalence of nutritional risk. The main factors associated with nutritional risk were being unmarried, lung cavitation, and low RBC and lymphocyte counts. Patients hospitalized with pulmonary TB should be evaluated for nutritional risk. Moreover, unmarried patients and patients with lung cavitation or low RBC or lymphocyte counts should be closely monitored.
