Abstract
Background: Tuberculosis (TB) remains a common disease globally. Even though the incidence rate of TB infection has decreased, mortality caused by TB cases is still high. Body mass index (BMI) is a popular and useful index to evaluate the nutrition status, and lower BMI is strongly associated with higher mortality. In Vietnam, however, the relationship between BMI and clinical and laboratary characteristics in patients with TB has not been extensively studied. Objectives: (1) To investigate the association of BMI and clinical and laboratory aspects in patients with TB, (2) To figure out changes in BMI of patients with TB after 1-month treatment. Method: All adults over 18 years old with TB who admitted to the Department of Tuberculosis of the Thua Thien Hue Central Hospital, were included in a prospective study from 4/2014 to 4/2015. Results: Gender and duration of TB were closely related to BMI of patients. The majority of participants had negative sputum AFB with level (-), at 68.3% and the common TB lesions didn’t have cavitary lesions on the chest X-ray and at grade I of ATS. The study also showed a significant change in BMI of participants after one month of treatment. Key words: BMI, changes in BMI, pulmonary tuberculosis
