Objective: To describe the number of hospital admissions due to child malnutrition in Brazil. Methods: This is an epidemiological, descriptive, observational study with a quantitative approach, focusing on hospitalizations of children aged 1 to 9 years due to malnutrition across Brazilian regions. Data were collected from the Notifiable Diseases Information System (SINAN) between January 2012 and December 2022. Results: A total of 20,855 cases of child malnutrition were reported in Brazil. The years with the highest incidence within the analyzed period were 2012, with 13.0% of cases, followed by 2014, with 12.4%. The Northeast region showed the highest number of hospitalizations, accounting for 34.2% of the total cases. Reports of malnutrition were more common among males (50.9%), children aged 1 to 4 years (70.9%), and those self-identified as brown (40.8%). Regarding the number of deaths, 286 cases were reported, with the highest incidence in 2012 (12.9%). Conclusion: Although there has been a significant decrease in hospitalizations due to malnutrition over the study period, child malnutrition remains a public health issue, driven by fac- tors related to socioeconomic inequalities and disparities in health services across the country.
