A new study published in The Journal of Pediatrics investigated nutritional status and growth status of pediatric patients with functional gastrointestinal disorders (FGIDs) and examined the relationship between nutritional status and linear growth in these children. In this study, 102 pediatric patients diagnosed with functional constipation (FC), irritable bowel syndrome (IBS), or functional abdominal pain (FAP) between 2013 and 2015 were subjected to anthropometric measurements. Body fat percentage was obtained with bioelectrical impedance analysis. While indices of the nutritional status and body proportions were calculated and adjusted for age and sex. The findings revealed that excessive body weight and excessive flabbiness were the most common in children with IBS. While being underweight was most common in children with FAP, whereas fat deficiency was equally frequent in the FAP and in FC groups. Additionally, short stature was the most common in children with FC. Meanwhile, children with IBS were the best nourished and the tallest for age and sex due to increased trunk length. Body height and linear body proportions adjusted for age and sex were positively associated with body weight and body fatness in the total sample. From the results, it was inferred that children with FGIDs present various linear growth abnormalities that are associated with body weight and body flabbiness. It was further stated that although excessive body weight and body fat are common in children with IBS; pediatricians should be aware of the risk of malnutrition in children with other FGIDs.
