“…These results were in line with the previous studies which reported that, the percentage of subcutaneous adipose tissue was higher in females bodies than that of males due to their sedentary lifestyle, less involvement in vigorous physical activities and less expenditure of energy [7,16]. Although, an agreement has been proved between BMI and TST in some studies [29,38], BMI may not be a useful parameter in measuring the subcutaneous body fat of children, because changing the body shape occurs in childhood. Furthermore, it fails to differentiate the fat from the muscle mass and may classify children with large muscle into obese children group [18].…”

Background: The present study was conducted to jointly assess some specific factors related to body fat measures using a multivariate multilevel analysis in a representative sample of Iranian mid-adolescents. Methods: This study was conducted among 2538 students (1286 boys) aged 14-20 years old, who were randomly selected among 16 public high schools by multi-stage random sampling procedure from all education districts of Shiraz, Iran. Data on demographic characteristics, family history of obesity, physical activity, socioeconomic (SES) variables and screen time were collected. Height, weight, triceps (TST), abdominal (AST), and subscapular (SST) skinfold thickness were measured and their body mass index (BMI) was calculated. A multivariate multilevel approach was used to analyze the factors associated with obesity measures of the TST, AST, SST at the child and district levels. Results: In this study, the prevalence of overweight and obesity was estimated to be 10.2 and 5.1%, respectively. Overall, the major portion of the total variance in TST (97.1%), AST (97.7%), and SST (97.5%) was found at the child level. The results of multivariate multilevel method revealed that being girls, having a family history of obesity, and SES were significantly associated with increasing of three body fat measures (all the p-values were less than 0.05). There were significant positive associations between moderate to vigorous physical activities with AST and SST (for AST: β =2.54, SE = 1.40, p = 0.05; for SST: β =2.24, SE = 1.20, p = 0.05). Compared to children in 14-16 age group, children in age group 16-18 years had less TST (β = − 0.67, SE = 0.34, p = 0.04). Furthermore, other age groups and screen time did not play an important role in three outcome variables. Conclusions: The results showed some factors that contribute to three body fat measures. Therefore, it is necessary to develop effective interventions to prevent the effects of individual and environmental undesirable factors on childhood obesity in both family and community levels.

Background The present study was conducted to assess some specific factors related to anthropometric indices in a representative sample of Iranian mid-adolescents. It also aimed to investigate the relationship between three anthropometric indices using a multivariate multilevel approach.Methods This study was conducted among 2538 students (1286 boys) aged 14 -20 years old, who were randomly selected among 16 high schools by multi-stage random sampling procedure from 4 education districts of Shiraz, Iran. Data on demographic characteristics and anthropometric measures were collected. Anthropometric indices were estimated by the calibrated tools. A multivariate multilevel model was used to assess the predictor variables associated with obesity measures of the triceps (TST), abdominal (AST), and subscapular (SST) skinfold thickness.Results In this study, the prevalence of overweight and obesity was estimated to be 10.2 and 5.1%, respectively. Hierarchical models showed that, the outcome variables were correlated at the child and district levels. Positive associations were observed between the sex, family history of obesity, and moderate and high Socio-Economic Status (SES) with three anthropometric indices. Moreover, there were positive associations between moderate to vigorous physical activities with AST and SST, but they were not statistically significant at a significance level of 0.05.Conclusions Our findings revealed that, TST, AST, and SST could be useful indices for measuring the adiposity in mid-adolescents. In addition, the effect of the district level on the predictor variables highlights the important role of the environmental factors on the childhood obesity.
