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.

This study aims to examine association between sodium intake and overweight/obesity among Chinese children and adolescents. Data were obtained from China National Nutrition and Health Surveillance (CNNHS), 2010–2012. All participants recruited in this study aged 7–18 years old and provided complete dietary data on three-day consecutive 24 h dietary recalls combining with the household weighing method. Body Mass Index (BMI) was used to define overweight/obesity, and waist-to-height ratio (WHtR) was used to define abdominal obesity. Sodium intake showed association with risk of overweight/obesity assessed by BMI in the highest tertile group with OR of 1.48 (95%CI 1.13–1.94) and 1.89 (95%CI 1.33–2.67) for WHtR. After adjusted for gender, age, household income, area, energy, carbohydrates, protein, fat, saturated fatty acids, and fiber intake, the relationship between sodium intake and overweight/obesity and abdominal obesity are not changed. The same results were founded in subjects aged 10–18 years old. Our results reveal a positive association between sodium intake and overweight/obesity in Chinese children and adolescents, independent of energy consumption.

Abstract Purpose Zinc plays an important role in metabolic processes in human organisms and is indispensable in many enzymatic processes. To date, few studies have assessed the association between serum zinc and metabolic risk factors in children and adolescents. The aim of the present study was to examine whether serum zinc concentrations was associated with metabolic risk factors in Chinese children and adolescents. Methods This study was a cross-sectional analysis of data from the 2016-2017 China National Nutrition and Health Surveillance for Children and Nursing in Jiangsu Province. A total of 3241 participants aged 6 -17years were included. Metabolic risk factors included fasting glucose (FG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C), systolic blood pressure and diastolic blood pressure. Data were analyzed using multivariable linear regression and generalized additive models, which were adjusted for age, gender, high sensitive C-reactive protein, estimated glomerular filtration rate, body mass index and region of residence, to assess the associations of serum zinc concentrations with metabolic risk factors. Results We observed a negative association between serum zinc concentrations and FG (coefficient = -0.532; 95% CI: -0.569, -0.495; p< 0.001). Moreover, TC (coefficient = 0.175 ; 95% CI 0.127, 0.222; p< 0.001), HDL-C (coefficient = 0.137 ; 95% CI 0.082, 0.193; p< 0.001) and LDL-C (coefficient = 0.195 ; 95% CI 0.128, 0.263; p< 0.001) were found to be positively associated with zinc levels. A generalized additive model showed that the negative association between serum zinc and FG was weak at lower serum zinc concentrations, and was stronger with the increase in serum zinc concentrations. Additionally, a U-shaped association between serum zinc and TG was observed. Conclusions Serum zinc concentrations were associated with FG, TC, TG, HDL-C and LDL-C levels in Chinese children and adolescents. Lower levels of serum zinc were more likely related to a poor metabolic status.

AbstractThe objective of this study was to examine the cross-sectional relationship between homeostasis model assessment for insulin resistance (HOMA-IR) and serum 25-hydroxyvitamin D (25-OHD) level in Chinese children and adolescents.Anthropometric indices, lipid metabolic profile, and serum levels of glucose, insulin and 25-OHD were determined among 278 healthy prepubertal and pubertal, normal and overweight/obese children and adolescents aged 8–18 years between March 2014 and February 2015.HOMA-IR was significantly different across vitamin D statuses (p<0.001), even after adjusting for body mass index (BMI) (p=0.035) and waist-to-height ratio (p=0.044); the difference was not significant between the vitamin D deficient and insufficient groups (p=0.120). HOMA-IR negatively correlated with serum 25-OHD level for all subjects (ROur findings supported that lower vitamin D status is strongly associated with worse HOMA-IR.
