Background. Malnutrition is observed frequently in patients with pulmonary tuberculosis (TB). Subjective global assessment (SGA) is a subjective method of measuring nutrition status. Few studies have investigated the prognostic role of SGA in patients with pulmonary TB. Methods. The authors evaluated 39 patients with pulmonary TB. The SGA classification technique was performed; patients were classified as well nourished (A), moderately malnourished (B), or severely malnourished (C). Results. The mean patient age was 67.7 ± 19.0 years, and the majority of patients were male (64.1%). Twelve patients (30.1%) were categorized as SGA class A, 14 patients (35.9%) as class B, and 13 patients (33.3%) as class C. The SGA-A group had a median survival of 438 days (95% confidence interval, 366-509), the median survival of the SGA-B group was 344 days (251-436), and the median survival of the SGA-C group was 118 days (37-198); these survival rates were significantly different (P < .001). Conclusion. SGA appears to be a useful tool for nutrition assessment of patients with pulmonary TB. In addition, SGA may be a prognostic indicator of survival in patients with pulmonary TB.
