Nutritional status in children has been considered an indicator of health and well-being at the individual and population levels (1). Both the malnutrition prevalence and the risk for development of malnutrition have been consistently reported as high in hospitalised children (2, 3). However, this problem remains largely unrecognised by healthcare workers. Due to the likelihood of the prevention of nutrition-associated complications, such as the slowing of growth and increased susceptibility to various infections, as well as prolonged hospitalisation, early detection of the risk for malnutrition among hospitalised children has been considered essential (3, 4).The importance of identifying those children at increased nutritional risk has led to the development of a number of nutritional risk screening (NRS) tools. However, there is a paucity of data on their application in clinical practice and the degree of inter-tool agreement and a consensus regarding which screening tool to use has not yet been reached (3,5). The most recent instrument, STRONGkids, has been developed accordBackground: High prevalence of malnutrition along with the risk for the development of malnutrition in hospitalised children has been reported. However, this problem remains largely unrecognised by healthcare workers. Aims: To determine the prevalence of malnutrition and effectiveness of STRONGkids nutritional risk screening (NRS) tool in the identification of malnutrition risk among pediatric surgical patients. Study Design: Cross-sectional study. Methods: A total of 494 pediatric surgical patients (median age 59 months, 75.8% males) were included in this prospective study conducted over 3 months. SD-scores <-2 for Body Mass Index (BMI) for age or weight-for-height (WFH) and height-for-age (HFA) were considered to indicate acute and chronic malnutrition, respectively. The STRONGkids NRS tool was used to determine risk for malnutrition. Results: Malnutrition was detected in 13.4% in this group of pediatric surgical patients. Acute malnutrition was identified in 10.1% of patients and more commonly in patients aged ≤60 months than aged >60 months (13.4 vs. 6.6%, p=0.012). Chronic malnutrition was identified in 23 (4.6%) of patients with no significant difference between age groups. There were 7 (1.4%) children with coexistent acute and chronic malnutrition. The STRONGkids tool revealed that 35.7% of patients were either in the moderate or high risk group for malnutrition. Malnutrition, as revealed by anthropometric measurements, was more likely in the presence of gastrointestinal (26.9%, p=0.004) and inguinoscrotal/penile surgery (4.0%, p=0.031), co-morbidities affecting nutritional status (p<0.001) and inpatient admissions (p=0.014). Among patients categorized as low risk for malnutrition, there were more outpatients than inpatients (89.3 vs. 10.7%, p<0.001) and more elective surgery cases than emergency surgery cases (93.4 vs. 6.6%, p<0.001). Conclusion: Providing data on the prevalence of malnutrition and risk of malnutrition in a prospect...
