Background: For pediatric patients who are hospitalized, full feeding nutritional needs is not only to improve BMI but also very useful for accelerating the healing process, shortening the treatment period, reducing complications, reducing morbidity and mortality, and preventing malnutrition due to treatment or medical action. This study aimed to describe the association between the achievement of full feeding with mortality in children. Method: The retrospective study was conducted in Pediatric Ward at Sanglah General Hospital, Denpasar Bali period January to December 2021. The inclusion criteria in this study were all pediatric patients who were hospitalized at pediatric wards Sanglah Hospital Denpasar. Inclusion criteria were children aged 1 month-18 years old. Samples were taken by total sampling. Quantitative variables were tested using variables that scale categorical data will be displayed in the form of absolute numbers and percent. The results of the descriptive analysis are presented using a chi-square test used to analyze all indirect variables (depending on whether the assumptions were met). The results of multivariate analysis were with logistic regression. The results were considered statistically significant at p < 0.05. Result: Total 258 subjects who met the inclusion criteria. Multivariate analysis with logistic regression shows full feeding (Exp B 0.24; 95% CI 0.032-0.27; P 0.006), nutritional status (Exp B 0.23; 95% CI 0.31-1.55; P 0,004) was statistically significant for mortality. Conclusion: Full feeding and nutritional status were associated with an increase in child mortality.
