“…It was also higher than the prevalence observed in children younger than 10.9 years from the Northeast and Southeast regions of Brazil, where the authors found excess weight in 18.1% of the sample (21) . The values observed in this study were also higher than those observed in school children from 6 to 10 in the city of Brasília, where the prevalence of overweight among children was 20.1% (22) . When compared to the findings of Guedes (21) who investigated school children in Londrina, state of Paraná, and found 24.5% of children with excess weight in the age group from 7 to 10 years, the values obtained in this study were quite similar (24.4%).…”

“…Of the anthropometric variables, BMI indicated the greatest correlation with the body composition assessment methods. This correlation was positive and significant and was consistent with the findings of other studies [17,18]. BIA-Bioelectrical impedance analysis; ST-skinfold thicknesses; BMI -Body Mass Index Note: Loss of three (WC and WHR) and six (BIA and ST) individuals due to patient non-attendance or absence of the equipment due to technical problems Table 1: Demographic and anthropometric characteristics of the participants.…”

“…In contrast to BMI and WC, WHR demonstrated a weak and non-significant correlation with %BF. Similar studies have suggested that WHR is not a strong indicator of body fat [4,17] and shows weak correlations with other anthropometric measures like BMI [18,24]. WHR has been more strongly related to pelvic bone size than to body fat distribution [25].…”

Background: Excess body fat is associated with increased morbidity and mortality. Accordingly, it is important to choose reliable, simple and straightforward methods for measuring body composition in clinical practice. The aim of this study was to verify the concordance between body composition obtained by Skinfold Thickness (SF) and Bioelectrical Impedance Analysis (BIA) as well as their correlation with anthropometric indices. Methods: The study was conducted from August 2007 to July 2009 among the adults and elderly patients (n = 85) receiving nutritional counseling at a primary health care unit in a Brazilian city. It was investigated all patients seen in the period. The following indices were used for comparison: Body Mass index (BMI), Waist Circumference (WC), Waist-Hip Ratio (WHR) and body composition evaluated by BIA and the sum of skinfolds (tricipital, bicipital, subscapular and suprailiac). The statistical analyses included the Kolmogorov-Smirnov test, Student's t-test, Wilcoxon signed-rank test, the Pearson and Spearman correlation tests and the Bland-Altman method. Results: Eighty-five individuals were evaluated, predominantly women (91.8%) and overweight individuals (92.8% adults, 89.7% elderly), with a mean age of 51.8 ± 13.0 years (22;85). The percentage of body fat estimated by SF was significantly higher than that estimated by BIA (42.8%; 95% CI: 12.6-49.2 vs. 40.4%; 95% CI: 21.0-51.2; p<0.001). However, a moderate correlation (r = 0.58; p<0.001) and strong concordance [0.9797 (LC95%=-8.0519; 10.0113)] were observed between the two methods. Significant correlations were found between BMI and WC, but not WHR, with respect to body fat estimated by BIA and SF (r = 0.453 to 0.707; p<0.05). BIA presented stronger correlations with BMI and WC (r = 0.707 and 0.605, respectively) compared with SF (r = 0.493 and 0.453, respectively). Conclusion: Strong concordance and a significant correlation were observed between BIA and SF, suggesting their validity in measuring body fat among overweight individuals. However, BIA appears to present better results when considering its higher correlation with the anthropometric indicators used.

“…Using data from pre‐pubertal and early adolescent boys and girls, significant correlations have been reported between percentage body fat (%BF) and body mass index (BMI) (11,12). These findings support the use of BMI as a screening tool for adiposity.…”

Screening for body‐weight disorders in Nigerian children using contrasting definitions

Several indices for body-weight disorders exist in scientific literature, but it is inconclusive whether or not they can yield comparable results when applied to Nigerian children. The prevalence of weight disorders in Nigerian children was examined using the Centre for Disease Control and Prevention (CDC) body mass index (BMI) for age charts and the International Obesity Task Force's (IOTF) age- and sex-specific BMI cut-off points. Participants were 2015 pupils (979 boys and 1036 girls) aged 9-12 years, attending 19 public primary schools in Makurdi, Nigeria. Stature and body mass were measured using standard techniques. Results were analysed using student t-test and Chi-squared statistics, with the probability level set at
