AI Article Synopsis
- * 400 participants aged 8-15, split into overweight/obese and normal weight groups, were analyzed for various cephalometric measurements and dental stages, showing significant differences linked to BMI.
- * Results indicate that overweight/obese individuals have advanced craniofacial growth and dental age compared to normal-weight peers, suggesting the need for timely orthodontic interventions.
Article Abstract
Background: The prevalence of childhood and adolescent obesity is increasing worldwide. Reports suggest that elevated body mass index (BMI) is associated with larger craniofacial dimensions and advanced dental and skeletal development. Such an association is important for timing orthodontic treatment relative to pubertal growth and dental eruption.
Materials And Methods: To evaluate associations between BMI, craniofacial morphology, dental age, and cervical vertebrae maturation staging (CVMS), 400 participants were consecutively selected (8-15 years, n = 200 overweight and obese BMI >85%, 200 normal weight) from the University of North Carolina database. Records were analysed for cephalometric measures, Demirjian index values, and CVMS. Bivariate statistics and linear regression analysis evaluated whether CVMS, dental age, and cephalometric dimensions varied with BMI.
Results: Overweight/obese children and adolescents had a proportionally larger bimaxillary prognathic skeletal pattern compared to those of normal weight. These cephalometric measurements [articulare-gnathion (Ar-Gn), condylion-anterior nasal spine (Co-ANS), sella-gonion (S-Go), nasion-menton (N-Me), anterior nasal spine-menton (ANS-Me), sella-nasion-A point (SNA), sella-nasion-B point (SNB), and sella-nasion-pogonion (SNPg)] were significantly different [statistically (P < 0.05) and clinically (>2 mm or >2 degrees)] between the two study groups, with a linear relationship between BMI percentile and craniofacial dimension. The overweight/obese BMI group had a mean dental age 1.4 years advanced relative to the normal weight group (P < 0.05), with an advancement of nearly one CVM stage between the ages of 12 and 14 (P < 0.05).
Limitations: The study is retrospective.
Conclusions: Obese/overweight children and adolescents have proportionally larger antero-posterior and vertical dimensions and are more likely to experience advanced dental and skeletal maturation. Obese/overweight subjects may enter their growth spurt at a younger age and have earlier eruption of teeth, affecting treatment timing. BMI percentile should be a consideration for orthodontic treatment in growing patients.

Avoidant/Restrictive Food Intake Disorder in a Pediatric Obese Patient.

Pediatrics, Dr. Efrain Flores Pediatrics, Bolingbrook, USA.
Avoidant/restrictive food intake disorder (ARFID) can present with limited food variety, intake, or aversions. The symptoms can manifest at any age and typically appear in the first few years of life. The prevalence of ARFID varies widely among clinical and non-clinical populations, and its diagnosis requires trained health professionals to ensure early detection and prevention of poor outcomes.

Background/objectives: The primary aim of this study was to characterize athletes approaching an outpatient interdisciplinary and multidisciplinary consultation structure for athletes with a suspected relative energy deficiency in sport (REDs) cross-sectionally and longitudinally to prove treatment efficacy.
Methods: Data of 58 athletes suspected of REDs were collected at the onset (t) and completion (t) of interdisciplinary and multidisciplinary REDs treatment (clinical practice) between January 2019 and December 2022. The data included extracted information from medical records, anthropometric characteristics, physical performance diagnostics, laboratory values, dietary records, and partially gynecological and psychosomatic diagnostics.
Cross-Sectional Analysis of IL-6, TNF-α, Adiponectin, Leptin, and Klotho Serum Levels in Relation to BMI Among Overweight and Obese Children Aged 10-14 in La Rioja, Spain.

Background: Childhood obesity is a major public health concern, being linked to an increased risk of metabolic disorders and cardiovascular disease. Even in childhood, obesity is associated with systemic low-grade inflammation, which is a critical factor in the development of atherosclerosis and a predictor of cardiovascular morbidity and mortality.
Objectives: To describe the prevalence of obesity and examine the relationship between IL-6, TNF-α, adiponectin, leptin, the leptin/adiponectin (L/A) ratio, and Klotho levels with BMI in children.

This study examined the associations between age, adiposity, physical activity, sedentary behavior, and elevated blood pressure (BP) in 2901 Portuguese children and adolescents aged 2-18. BP, body mass index (BMI), waist-to-height ratio (WHtR), physical activity, and sedentary behavior were measured. Elevated BP was defined as a BP above the 90th percentile for age, sex, and height.
