TB can contribute to nutritional disorders, while treatment with anti-tuberculosis drugs (OAT) may help improve nutritional status. This study aims to evaluate the differences in nutritional status among toddlers with pulmonary TB before and after receiving OAT treatment at Dr. Moewardi Regional General Hospital, Indonesia. Subjects and Method: This study utilized a comparative analytical design with a cross-sectional approach and employed a retrospective purposive sampling technique. It was conducted at Dr. Moewardi Regional General Hospital from 2017 to 2024 using a total sampling method, identifying the nutritional status of toddlers before and after OAT administration.

The highest nutritional status before OAT treatment was malnutrition (59.52%) while after treatment it was good nutrition (66.66%). The nutritional status of toddlers was higher (Mean = 2.90; SD = 0.57) than before (Mean = 2.12; SD = 0.63), and this result was statistically significant (p<0.001).
