The aim of the study is to examine the validity in predicting body fat percentage (%BF) of different bioelectrical impedance (BIA) devices among Chinese children and adolescents. A total of 255 Chinese children and adolescents aged 9–19 years old participated in the study. %BF was assessed by BIA scales, namely, Biodynamics-310 (Model A), Tanita TBF-543 (Model B), Tanita BC-545 (Model C), and InBody 520 (Model D). Dual-energy X-ray absorptiometry (DXA) was used as the criterion measurement. Lin’s concordance correlation coefficients of estimated %BF between Model A, Model B, Model C, and DXA showed poor agreements for both genders. Moderate agreements for %BF were found between DXA and Model D measurements. In boys, differences in %BF were found between DXA and Model B and Model C. No significant %BF differences were found between Model A, Model D, and DXA. However, the two BIA analyzers showed a significant positive correlation between the bias and average %BF between BIA and DXA. In girls, differences in %BF were observed between Model B, Model C, Model D, and DXA. Model A and DXA showed no significant differences of %BF; however, the bias and the average %BF between the BIA and DXA had a significant positive correlation. Using embedded equations in BIA devices should be validated in assessing the %BF of Chinese children and adolescents.

AbstractThis study experimentally evaluates the risk preferences of children and adolescents living in an urban Chinese environment. We use a simple binary choice task that tests risk aversion, as well as prudence. This is the first test for prudence in children and adolescents. Our results reveal that subjects from grades 5 to 11 (10 to 17 years) make mostly risk-averse and prudent choices. The choices of 3rd graders (8 to 9 years) do not differ statistically from risk neutral benchmarks, but at the same time they make mostly prudent choices. We also find evidence for a transmission of risk preferences. There is positive correlation between all children’s and their parents’ tendency to make risk-averse choices. There is also positive correlation between girls’ and their parents’ tendency to make prudent choices.

Background: The prevalence of childhood obesity is increasing globally. This has severe implications for cardiometabolic risk including hypertension. South Asian children are particularly vulnerable given their unique phenotype which results in higher body fat at similar body mass index (BMI) levels compared to Europeans. As a result, we sought to explore the association between adiposity indicators and blood pressure, and to compare the strength of these indicators in determining hypertension in South Asian children and adolescents. Methods: Children ages 7-8 and 14-15 with South Asian origin were recruited from two Canadian cities. They were then assessed for height, weight and waist circumference (WC). Waist to height ratio (WHtR), and BMI were calculated. Body fat percentage was determined by bioelectrical impedance analysis. Blood pressure (BP) was assessed three times using an automated device. All variables (except body fat percentage) were transformed to z-scores using published standards. Unadjusted and adjusted (age, sex, household income, exposure to bullying or violence) logistic regression was used to explore associations between adiposity and hypertension. Subsequently, area under the curve (AUC) analysis was used to explore the strength of the adiposity metrics in determining hypertension. Results: This study consisted of 306 boys and 402 girls (n=762) with mean age 9.5 (S.D 3.2) years. Significant association were detected in unadjusted models between the adiposity indicators with systolic and diastolic hypertension (p<0.0001 for all). In the fully adjusted model, the association between adiposity with systolic and diastolic hypertension remained after adjusting for covariates (p<0.01 for all). BMI was the strongest predictor of systolic hypertension (AUC= 0.791), while body fat percentage was the strongest for diastolic hypertension (AUC= 0.712). The other indicators were within close ranges in their ability to predict both systolic and diastolic hypertension. Conclusion: Significant associations were observed between adiposity indicators and hypertension. Moreover, the adiposity indicators were observed to be strong predictors of hypertension in AUC analysis. This highlights the relationship between adiposity and hypertension, and suggests that BMI, WC, WHtR and body fat percentage are good indicators of hypertension in South Asian children.
