“…Body mass and percentage body fat (% body fat) were measured with the Tanita SC-240 bio-electrical impedance scale (Arlington Heights, IL, USA), which has demonstrated acceptable validity for field studies [19]. Height was measured with a Seca 213 portable stadiometer (Hamburg, Germany) [14].…”

The purpose of this study was to determine the association between regular (sugar containing) and diet (artificially sweetened) soft drink consumption and obesity in children from 12 countries ranging in levels of economic and human development. The sample included 6162 children aged 9–11 years. Information on soft drink consumption was obtained using a food frequency questionnaire. Percentage body fat (%BF) was estimated by bio-electrical impedance analysis, body mass index (BMI) z-scores were computed using World Health Organization reference data, and obesity was defined as a BMI > +2 standard deviations (SD). Multi-level models were used to investigate trends in BMI z-scores, %BF and obesity across categories of soft drink consumption. Age, sex, study site, parental education and physical activity were included as covariates. There was a significant linear trend in BMI z-scores across categories of consumption of regular soft drinks in boys (p = 0.049), but not in girls; there were no significant trends in %BF or obesity observed in either boys or girls. There was no significant linear trend across categories of diet soft drink consumption in boys, but there was a graded, positive association in girls for BMI z-score (p = 0.0002) and %BF (p = 0.0001). Further research is required to explore these associations using longitudinal research designs.

“…We previously conducted a validation study of the Tanita SC-240 scale among White and African American children and the results demonstrated that the scale had acceptable accuracy for estimating PBF in field studies. 13 However, the degree to which the validity of the scale varied across sites and may have impacted the results is not known. Each BIA device uses proprietary equations to estimate body fat, and this may impact the level of adiposity obtained with each device; however, this is unlikely to impact the comparisons among countries given that the same scale was used at all research sites.…”

Association between body mass index and body fat in 9–11-year-old children from countries spanning a range of human development

The purpose was to assess associations between body mass index (BMI) and body fat in a multinational sample of 9-11-year-old children. The sample included 7265 children from countries ranging in human development. Total body fat (TBF) and percentage body fat (PBF) were measured with a Tanita SC-240 scale and BMI z-scores (BMIz) and percentiles were computed using reference data from the World Health Organization and the U.S. Centers for Disease Control and Prevention, respectively. Mean PBF at BMIz values of − 1, 0 and +1 were estimated using multilevel models. Correlations between BMI and TBF were 40.90 in all countries, and correlations between BMI and PBF ranged from 0.76 to 0.96. Boys from India had higher PBF than boys from several other countries at all levels of BMIz. Kenyan girls had lower levels of PBF than girls from several other countries at all levels of BMIz. Boys and girls from Colombia had higher values of PBF at BMIz = − 1, whereas Colombian boys at BMIz 0 and +1 also had higher values of PBF than boys in other countries. Our results show a consistently high correlation between BMI and adiposity in children from countries representing a wide range of human development.International Journal of Obesity Supplements (2015) 5, S43-S46; doi:10.1038/ijosup.2015.18 INTRODUCTIONBody mass index (BMI) is the most widely used marker of obesity in both children and adults. Although BMI cannot differentiate between lean and fat tissue, it is correlated with more direct markers of adiposity across the lifespan. 1-4 Further, BMI has been shown to be a good indicator of excess adiposity in children, 5,6 although there is evidence of moderate heterogeneity in its clinical usefulness, largely explained by differences in race, obesity definition and type of reference data. 7 Most research to date on the association between BMI and body fat has been conducted in high-income countries, and there is a paucity of data on associations among children from low-and middle-income countries. The purpose of this study was to assess the associations between BMI and adiposity in a sample of 9-11-year-old children from countries spanning a wide range of socioeconomic status and human development, and to test for differences in the associations between countries. MATERIALS AND METHODSThe sample included a total of 7265 children 9-11 years of age (3883 girls) from sites in 12 countries (Australia, Brazil, Canada, China, Colombia, Finland, India, Kenya, Portugal, South Africa, the United Kingdom and the United States). 8 The International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) protocol was approved by the Institutional Review Board at the Pennington Biomedical Research Center (Coordinating Center) as well as the Ethical Review Boards at each participating institution. Written informed consent was obtained from parents or legal guardians, and child assent was also obtained before participation in the study as required by local Ethical Review Boards.Body mass and percentage body fat (PBF; %) were measured ...

“…Body composition was estimated by bioelectrical impedance analysis (BIA) using the Tanita Ò SC-331s Total Body Composition Analyzer, which has been validated for children of 5 years old or more. 47 Briefly, BIA measures the electrical impedance, which is the resistance of body tissues to an electric flow. This allows estimating the body weight as well as fat and lean masses (in kg and percentage).…”

Placental lipoprotein lipase DNA methylation alterations are associated with gestational diabetes and body composition at 5 years of age

et al. 2017

Gestational diabetes mellitus (GDM) is associated with obesity in childhood. This suggests that consequences of in utero exposure to maternal hyperglycemia extend beyond the fetal development, possibly through epigenetic programming. The aims of this study were to assess whether placental DNA methylation (DNAm) marks were associated with maternal GDM status and to offspring body composition at 5 years old in a prospective birth cohort. DNAm levels were measured in the fetal side of the placenta in 66 samples (24 from GDM mothers) using bisDNA-pyrosequencing. Anthropometric and body composition (bioimpedance) were measured in children at 5 years of age. Mann-Whitney and Spearman tests were used to assess associations between GDM, placental DNAm levels at the lipoprotein lipase (LPL) locus and children's weight, height, body mass index (BMI), body fat, and lean masses at 5 years of age. Weight, height, and BMI z-scores were computed according to the World Health Organization growth chart. Analyses were adjusted for gestational age at birth, child sex, maternal age, and pre-pregnancy BMI. LPL DNAm levels were positively correlated with birth weight z-scores (r D 0.252, P D 0.04), and with midchildhood weight z-scores (r D 0.314, P D 0.01) and fat mass (r D 0.275, P D 0.04), and negatively correlated with lean mass (r D ¡0.306, P D 0.02). We found a negative correlation between LPL DNAm and mRNA levels in placenta (r D ¡0.459; P < 0.001), which highlights the regulation of transcriptional activity by these epivariations. We demonstrated that alterations in fetal placental DNAm levels at the LPL gene locus are associated with the anthropometric profile in children at 5 years of age. These findings support the concept of fetal metabolic programming through epigenetic changes.
