The analyzed data of the 532 cases of this study.

BackgroundMalnutrition is a significant risk factor contributing to the progression of the elderly with pulmonary tuberculosis (TB). This study aimed to evaluate the nutritional status of the elderly with pulmonary TB using the Mini Nutritional Assessment (MNA) and explore the relationship between their nutritional status and physical function.MethodsThis was a cross-sectional survey study. Data collection was from July 2023 to March 2024. 532 the elderly with pulmonary TB who were admitted to a tertiary infectious disease hospital in Chengdu were included in this analysis. The nutritional status of the patients was evaluated using MNA, and they were divided into well-nourished group (≥24 points) and abnormal-nourished group (ResultsThere were 109 cases (20.5%) in well-nourished group and 423 cases (79.5%) in abnormal-nourished group. Compared with well-nourished group, the abnormal group showed a decrease in the BBS scores [(52.55 ± 7.10) vs (43.20 ± 16.29), p p p p p p ConclusionsMalnutrition is common in the elderly with pulmonary TB. Nutritional status in these patients is associated with the BBS scores, the TUG, and the FTSST.
