Sarcopenia assessed using a questionnaire can predict in-hospital mortality in older patients with pulmonary tuberculosis.

Background & Aims: Pulmonary tuberculosis is a severe disease with a high mortality rate. However, whether sarcopenia is a risk factor for in-hospital mortality remains unclear. The SARC-F (five items: strength, assistance in walking, rising from a chair, climbing stairs, and falls) is a questionnaire developed to screen for sarcopenia.
