“…22.5% of children were identified as overweight or obese according to the IOTF classification, compared with 28.4% according to the WHO definition. Similar to the results reported herein, other studies also showed variations in the prevalence of overweight or obesity when using different weight classifications [16,17,18,19]. In this study, the prevalence of overweight was by 2.8% higher in girls and by 0.8% higher in boys according to the WHO definition, while the rate of obesity was by 2% higher in girls and by 6.1% higher in boys compared to the IOTF criteria.…”

Aims: To describe the prevalence of thinness, overweight, and obesity in Hungarian children (age 7.0-7.9 years) according to different classifications, to assess the progress between 2010 and 2016, and to investigate whether tendencies differ according to gender. Methods: A national representative sample was generated by two-stage cluster sampling, and a total of 2,651 children (50.9% boys; age 7.49 ± 0.3 years) were measured (weight and height) in October 2016. Population estimates were calculated using the WHO, IOTF, and national cut-offs. Results: Prevalence of thinness (including grade 1 and 2) was 12.6% based on the IOTF criteria and 15.6% based on the WHO definition. 22.5% of children were identified as overweight or obese according to the IOTF classification, compared with 28.4% according to the WHO definition. Between 2010 and 2016, each classiﬁcation indicated possible stability in overweight and obesity prevalence. In contrast, the prevalence of thinness grade 2 almost doubled in 6 years according to all definitions (p < 0.05). No significant gender difference was observed in the progress. Conclusion: Overweight and obesity appeared to be stable over 6 years, but we detected growing thinness rates. Routine collection of high-quality data that are based on standardized and comparable methods is essential to monitor the childhood obesity problem.

“…This hypothesis is supported by the fact that we did not find the same results for running when we used more direct measures of body fat. Interestingly, it has recently been suggested that the prevalence of overweight and obesity in schoolchildren may be twofold higher using WHO compared to IOTF criteria [47]. The results of the current study in young preschoolers support these observations (table 2).…”

Association between Body Composition and Motor Performance in Preschool Children

et al. 2017

Objective: Being overweight makes physical movement more difficult. Our aim was to investigate the association between body composition and motor performance in preschool children. Methods: A total of 476 predominantly normal-weight preschool children (age 3.9 ± 0.7 years; m/f: 251/225; BMI 16.0 ± 1.4 kg/m²) participated in the Swiss Preschoolers' Health Study (SPLASHY). Body composition assessments included skinfold thickness, waist circumference (WC), and BMI. The Zurich Neuromotor Assessment (ZNA) was used to assess gross and fine motor tasks. Results: After adjustment for age, sex, socioeconomic status, sociocultural characteristics, and physical activity (assessed with accelerometers), skinfold thickness and WC were both inversely correlated with jumping sideward (gross motor task β-coefficient -1.92, p = 0.027; and -3.34, p = 0.014, respectively), while BMI was positively correlated with running performance (gross motor task β-coefficient 9.12, p = 0.001). No significant associations were found between body composition measures and fine motor tasks. Conclusion: The inverse associations between skinfold thickness or WC and jumping sideward indicates that children with high fat mass may be less proficient in certain gross motor tasks. The positive association between BMI and running suggests that BMI might be an indicator of fat-free (i.e., muscle) mass in predominately normal-weight preschool children.

“…Weight status: The children were classified according to the definition of overweight and obesity by the International Obesity Task Force (IOTF) with three categories: normal weight (BMI<IOTF-25 kg/m 2 ), overweight with (BMI≥IOTF-25 kg/m 2 and BMI<IOTF-30 kg/m 2 ) and obese (BMI≥IOTF-30 kg/m 2 ) [13, 14]. Abdominal obesity in children was defined as WHtR greater or equal to 0.5 [15].…”

AIM:We aimed to study the relationships between circulating 25-hydroxyvitamin D [25(OH)D], insulin resistance and leptin-to-adiponectin (L/A) ratio in Guadeloupean children and adolescents and to analyse the changes in 25(OH)D levels after a 1-year lifestyle intervention program.METHODS:25(OH)D concentrations were measured via a chemiluminescence assay. Cardiometabolic risk factors, homoeostasis model assessment of insulin resistance (HOMA-IR), and adipokines were measured. The lifestyle intervention included dietary counselling, regular physical activity.RESULTS:Among 117 girls and boys (11–15 years old, 31.6% obese), 40% had vitamin D deficiency (25(OH)D levels < 20 ng/mL). With linear regression models where 25(OH)D and HOMA-IR acted as independent variables and age, sex, BMI, L/A ratio as covariates, 25(OH)D was significantly associated with HOMA-IR alone (P = 0.036). HOMA-IR was also associated with BMI z-score ≥ 2, L/A ratio and an interaction term BMI z-score ≥ 2*L/A ratio (P < 0.001 for all). After one year, in 78 children/adolescent, mean serum 25(OH)D increased significantly from 21.4 ± 4.9 ng/mL at baseline to 23.2 ± 6.0 after 1 year; P = 0.003 whereas BMI z-score, HOMA-IR and L/A ratio decreased significantly (P = 0.003, P < 0.001 and P = 0.012; respectively).CONCLUSION:The association between 25(OH)D and HOMA-IR, independently of obesity and the high prevalence of vitamin D deficiency should be considered in order to prevent the later incidence of T2DM. A healthy lifestyle including non-sedentary and outdoor activities could be a way for improving vitamin D status.
