Using the 2017-2018 National Health and Nutrition Examination Survey (weighted population size = 35,460,209; 8-18 years old; 52.1% males), we compared the obesity prevalence in children and adolescents between body mass index-based (BMI-based) and total percent body fat-based (BF%-based, measured by the dual-energy x-ray absorptiometry) cutoffs.…

Background: Balanced and adequate nutrition is important to improve the quality of life of children with intellectual disability but most of these children are negatively affected by nutritional problems. Objective: This study was conducted to determine the nutritional status and effect of the severity of intellectual disability on nutritional…

Background: School environments are important to consider for children's health. This study aims to determine if childhood peer bullying and school connectedness are associated with adolescent adiposity. Methods: A total of 3377 children from the age 9 child interview of the Fragile Families and Child Wellbeing Study had self-reported bullying and…

A growing body of literature suggests that youth with severe obesity are engaging in substance use. The purpose of the present study was to examine profiles of substance use among adolescents with severe obesity and examine how these profiles are associated with depressive symptomology using data from the Youth Risk Behavior Surveillance System.…

Mindful eating is a condition in which a person becomes aware of the moment while eating. Very few studies have investigated eating awareness in environments where physical activity is performed. The aim of this study is to investigate whether the duration and intensity of physical activity in adolescents aged 15-17 affects their nutritional…

We developed plank test standards, based on trunk lean mass-to-fat mass (LM/FM) ratio, in a sample of healthy Portuguese 10--18 year olds (n = 474, 46.4% female). Height and weight were measured and muscular endurance was assessed using the prone plank test. Trunk LM/FM ratio was determined using dual-energy x-ray absorptiometry. Plank standards…

Introduction: The aims of this study were to examine cross-sectional, and longitudinal association of different measures of obesity and physical fitness with cardiovascular disease (CVD) risk factors in adolescents with Down syndrome. Methods: Longitudinal analysis included 90 adolescents with Down syndrome. Obesity and physical fitness were…

The aim of this study is to examine the effects of life kinetic exercises on the performance of floor curling athletes. A total of 40 volunteer women, 20 in the experimental group and 20 in the control group, residing in the city center of Gaziantep, aged between 14 and 16 and doing floor curling, participated in the study. Life kinetic exercise…

We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…

We designed grip strength standards for youth by back-extrapolating cutpoints based on weakness at age 65. Existing standards, based on insufficient bone mineral content (BMC), were also compared in a nationally representative sample. Altogether, 6837 participants (n = 2199 [less than or equal to] 18.9 years of age) from the National Health and…

This study evaluated test-equating methods to enable comparisons and conversions between the vertical jump (VJ) and standing long jump (SLJ) tests. A total of 528 youth (280 males) performed VJ and SLJ, and their scores were randomly split as the calibration (C) sample (n = 478) and cross-validation (CV) sample (n = 50). SLJ scores of the C sample…

Stigmatization of overweight and obese individuals is common in interpersonal relationships. This study investigated longitudinal weight change patterns among Taiwanese adolescents and the relationship of weight change patterns with delayed romantic experience from late adolescence to young adulthood by using a representative panel survey.…

Individuals with autism spectrum disorder (ASD) may demonstrate atypical autonomic (ANS) responses; however, research remains inconsistent. This study examined parasympathetic response during social evaluation in 241 youth (10-13 years) with ASD (n = 138) or typical development (TD; n = 103). Diagnosis, age, pubertal development, and body mass…

The aim of this study is to determine the physical fitness levels of individuals with autism by comparing them with individuals in the early and middle adolescence periods with normal development and the needs of the individuals with autism in terms of physical fitness. This study is carried out at the Selçuklu Autism Foundation, which is the…

Achieving superior performance in swimming, as in other sports, depends on the customization of training for young athletes. The aim of this study was to investigate the effects of sprint interval trainings on heart rate and 50 m swimming performances of young male swimmers. 24 young male swimmers joined to the study by having their parents…
