Nutritional Status as a Risk Factor for Appendiceal Perforation in Pediatric Acute Appendicitis: Systematic Review

BMI-based classifications alone did not reliably predict perforation or complicated appendicitis. Albumin- and prealbumin-based indices were more consistently associated with disease severity, but the observational evidence does not establish causality and may reflect inflammatory severity at presentation. Prospective studies with standardized definitions and marker assessment are needed to evaluate incremental prognostic value beyond symptom duration and clinical severity scores.
