AI Article Synopsis
- - The study aimed to compare body composition changes, specifically fat mass index (FMI) and fat free mass index (FFMI), during puberty in obese versus normal-weight children in China, while also examining the influences of age and gender on these measurements.
- - Conducted with 356 children aged 7-15, body composition was measured using dual-energy x-ray absorptiometry (DEXA), which revealed that obese children had higher fat and fat-free mass compared to normal-weight peers.
- - Results indicated that the FMI and FFMI in obese children significantly increased with age and were consistently higher than those in normal-weight children of the same age and gender, with boys showing more pronounced differences than girls; suggesting these measurements are useful for
Article Abstract
Objective: To compare the changes in body composition, including fat mass index (FMI) and fat free mass index (FFMI) during puberty development of obese and normal-weight children in China, and to explore the effect of age and gender on body composition.
Methods: A total of 356 children at the age of 7-15 years were enrolled in this study. Body composition of 10 normal-weight and obese children in each age group was measured by dual-energy x-ray absorptiometry (DEXA). FFMI and FMI were calculated according to the following formula: FFMI (kg x m(-2)) = FFM(kg) / height2 (m2) and FMI (kg x m(-2)) = FM (kg) / height2 (m2).
Results: The fat mass and fat free mass of obese children were significantly higher than those of normal-weight children (P < 0.05). The FMI and FFMI of obese children increased significantly with age and were higher than those of the same sex, gender, and age normal-weight children (P < 0.05).
Conclusion: The levels of fat mass, fat free mass, FMI, and FFMI are different in obese and normal-weight children, and gender effects are significant in boys having higher levels of these indicators than in girls. FFMI and FMI can be used as monitoring indexes in weight control of obese children.

Effect of BMI and symptoms at celiac disease diagnosis on serology normalization after 2 years of a gluten-free diet in children.
J Pediatr Gastroenterol Nutr
January 2025
Department of Pediatrics, Division of Pediatric Gastroenterology, Hepatology, and Nutrition, Stony Brook Children's Hospital, Stony Brook, USA.
Objectives: To determine if after 2 years of consuming a gluten-free diet post celiac disease diagnosis, pediatric patients who were overweight or obese at diagnosis are less likely to normalize celiac disease serologies as compared with those who were normal weight or underweight at diagnosis. Secondary aims include characterizing how initial symptoms at presentation predict body mass index (BMI) change and serology improvement over the first 2 years of being on a gluten-free diet following diagnosis of celiac disease.
Methods: A retrospective chart review was performed that included all biopsy-proven celiac disease patients followed at Stony Brook Children's Hospital's Celiac Disease Center diagnosed between the years 2007-2022.
Association between Bioelectrical Impedance Parameters, Magnetic Resonance Imaging Muscle Parameters, and Fatty Liver Severity in Children and Adolescents.
Gut Liver
January 2025
Department of Radiology, Research Institute of Radiological Science and Center for Clinical Imaging Data Science, Yongin Severance Hospital, Yonsei University College of Medicine, Yongin, Korea.
Background/aims: To evaluate the associations between pediatric fatty liver severity, bioelectrical impedance analysis (BIA), and magnetic resonance imaging parameters, including total psoas muscle surface area (tPMSA) and paraspinal muscle fat (PMF).
Methods: Children and adolescents who underwent BIA and liver magnetic resonance imaging between September 2022 and November 2023 were included. Linear regression analyses identified predictors of liver proton density fat fraction (PDFF) including BIA parameters, tPMSA, and PMF.
Effects of underweight, overweight, and obesity on the body growth of preschoolers.

Article Synopsis
- The study analyzed the effects of underweight, overweight, and obesity on the growth of preschoolers by comparing their body shape measurements.
- No significant interactions were found for age or gender affecting BMI, but certain body measurements were identified as key indicators correlated with BMI.
- Obese preschoolers had notably larger body measurements compared to normal-weight children, while underweight children exhibited slower development in body shape metrics.
The Reproducibility and Reliability of Insulin Sensitivity and Secretion Indices in Children and Adolescents.
Pediatr Diabetes
December 2024
Department of Pediatrics, Division of Pediatric Endocrinology, University of Michigan, Ann Arbor, USA.
Context: Insulin sensitivity and secretion indices can be useful tools in understanding insulin homeostasis in children at risk for diabetes. There have been few studies examining the reproducibility of these measures in pediatrics.
Objective: To determine whether fasting or oral glucose tolerance test (OGTT)-derived insulin measures would be more reproducible and whether there would be differences based on weight, sex, race, and pubertal status.
Associations of adolescent obesity with hypertension, diabetes mellitus and polycystic ovaries in Arabs and Jews in Israel-a nationwide study.
Front Public Health
December 2024
Department of Public Health, Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel.
Background: Previous studies on the association of adolescent obesity with comorbid diseases in Israel were conducted predominantly in the Israeli Jewish population.
Goal: To compare associations of adolescent obesity with Hypertension (HTN), Diabetes Mellitus type 2 (DM2), and Polycystic ovaries (PCO), singly or in combination, between Arabs and Jews in Israel.
Methods: A cross-sectional study of 313,936 Arab adolescents aged 14-19 years between the years 2007-2022, and 289,616 adolescents in a matched Jewish comparison group.
