Lack of a standardized method of identifying and defining pediatric malnutrition has led to an inability to fully understand the prevalence of and impact that malnutrition has on pediatric patients and the healthcare system. The Subjective Global Nutritional Assessment (SGNA) is an assessment tool meant to determine presence and severity of malnutrition in pediatric populations. However, the anthropometric section of the tool contains some out-dated parameters. This has limited its clinical practicality. The aim of this paper is to propose updates to the anthropometrics section of the SGNA. A retrospective analysis of 153 SGNA's performed on children aged 1 month to 16 years was completed, comparing the original SGNA results to SGNA results incorporating updated anthropometric parameters for percentiles and ideal body weight. The category of length/height for age was updated to include z score cutoffs rather than percentiles, and ideal body weight was updated to z scores for weight for length or body mass index (BMI). Two serial growth questions were updated in wording only, to reflect z score trends. The results of the analysis showed these updates would have changed the rankings of eight patients (5%) for length/height for age, and 20 patients (13%) for ideal body weight to weight for length or BMI. Adjustments to these questions did not impact the overall SGNA rating. This study shows updates to the SGNA are not expected to have a significant impact on the validity of the tool and has the potential to improve its applicability to current day practice.
