Background The aim of this paper was to investigate whether BMI and fat percentage classification criteria, would classify a sample of 7–13 year old boys from a rural background in similar nutritional categories. Methods A cross-sectional study with a stratified random sampling included 601 rural boys (7–13 years old). Fat percentage criteria classification and BMI were calculated and compared. Maturity status, and age at peak height velocity (PHV) were indirectly determined. Statistical techniques included descriptive statistics, Pearson product correlation coefficients, the Kappa agreement test and the McNemar’s test. The level of statistical significance was set at p ≤ 0.05. Results All age groups presented with statistically significant high correlations between BMI and fat percentage, and low to medium correlations between fat percentage and maturity age (MA). Measurement of agreement between BMI and fat percentage classifications showed poor to fair agreements for all age grou...

The purpose of this observational prospective cohort study was to investigate the development and tracking of body mass index (BMI) of Ellisras rural children from preschool age into late adolescence from the Ellisras Longitudinal Growth and Health Study. Heights and weights of children were measured according to the standard procedures recommended by the International Society for the Advancement of Kinanthropometry twice a year from 1996 to 2003. In total, 2,225 children-550 preschool and 1,675 primary school-aged 3-10 years (birth cohorts 1993 to 1986) were enrolled at baseline in 1996 and followed through out the eight-year periodic surveys. In 2003, 1,771 children-489 preschool and 1,282 primary school-were still in the study. The prevalence of overweight was significantly higher among girls (range 1.6-15.5%) compared to boys (range 0.3-4.9%) from age 9.1 years to 14.9 years. The prevalence of thinness (severe, moderate, and mild) ranged from 7.1% to 53.7% for preschool children and from 8.0% to 47.6% for primary school children. Both preschool and primary school children showed a significant association between the first measurements of BMI and the subsequent measurement which ranged from B=0.2 (95% confidence interval [CI] 0.1-0.4) to B=0.8 (95% CI 0.6-0.9) for preschool and B=0.2 (95% CI 0.1-0.3) to B=0.7 (95% CI 0.6-0.8) for primary children. A significant tracking of BMI during 4-12 years of life was more consistent for preschool children (B=0.6 (95% CI 0.6-0.7) and for primary school children (B=0.6 (95%CI 0.5-0.6). Investigation of nutritional intake and physical activity patterns will shed light on how healthy these children are and their lifestyle.

Background: This study was designed to estimate overweight and obesity in school children by using contrasting definitions recommended by the Centers for Disease Control and Prevention (CDC) and the International Obesity Task Force (IOTF).Method: The sample size consisted of 1361 learners (n = 678 boys; n = 683 girls) aged 9–13 years who were randomly selected from Mpumalanga and Limpopo provinces of South Africa. A cross-sectional and descriptive design was used to measure the children’s anthropometric characteristics. Based on height and weight measurements, the children’s body mass index (BMI) was calculated and used to classify them as underweight, overweight and obese. Percentage body fat was calculated from the sum of two skinfolds (i.e. triceps and subscapular). Age-specific BMI, percentage body fat and sum of skinfolds were examined for the boys and girls.Results: A higher prevalence of overweight and obesity was found in boys and girls when the CDC BMI categories were used....

Body fat percentage of urban South African children: implications for health and fitness
The West Indian medical journal, 2013
To explore gender and racial profiling of percentage body fat of 1136 urban South African children attending public schools in Pretoria Central. This is a cross-sectional survey of 1136 randomly selected children (548 boys and 588 girls) aged 9-13 years in urban (Pretoria Central) South Africa. Body mass, stature, skinfolds (subscapular and triceps) were measured. Data were analysed using descriptive statistics (means and standard deviations). Differences in the mean body fat percentage were examined for boys and girls according to their age group/race, using independent t-test samples. Girls had a significantly (p = 0.001) higher percentage body fat (22.7 ± 5.7%, 95% CI = 22.3, 23.2) compared to boys (16.1 ± 7.7%, 95% CI = 15.5, 16.8). Percentage body fat fluctuated with age in both boys and girls. Additionally, girls had significantly (p = 0.001) higher percentage body fat measurements at all ages compared to boys. Viewed racially, black children (20.1 ± 7.5) were significantly (p...

Background: Childhood obesity has become a growing global epidemic. In South Africa, overweight and obesity during childhood and adolescence are rising. The objectives of this study were (i) to estimate the prevalence of overweight and obesity among selected students in Cofimvaba, a rural settlement in Eastern Cape province, South Africa, and (ii) to assess the accuracy of the mid-upper arm circumference (MUAC) and ultrasound triceps skin-fold thickness (TSF) methods of predicting these health parameters Methods: A cross-sectional study was conducted on 211 students (109 girls and 102 boys) selected randomly from five public schools in Cofimvaba and aged 6-19 years. The weight, height, MUAC and TSF were determined by standard techniques. Data obtained were subjected to descriptive statistics, Pearson correlations and receiver operating characteristic (ROC) curve analysis. P < 0.05 was considered statistically significant. Result: Overall 1.9% (1.8% girls and 2.0% boys) of the respondents were underweight, 14.8% (21.1% and 7.8% boys) were overweight and 2.8% (4.6% girls and 1.0% boys) were obese. The prevalence of overweight and obesity was significantly higher (p < 0.05) in girls than boys during adolescence but there was no gender difference in children (6-9 years). Most of the students (80.6%) had a healthy weight, with boys being significantly (p < 0.05) healthier than girls. The BMI showed significant strong correlations with MUAC (r = 0.926; p < 0.001) and TSF (r = 0.643; p < 0.001). ROC curve analysis gave an area under the curve (AUC) of 0.795 (95% CI, 0.761-0.889) and 0.835 (95% CI, 0.771-0.899) for MUAC and TSF respectively. Conclusion: The study found a high prevalence of overweight children in the sample and a low prevalence of stunting and underweight. The adolescent girls are at a higher risk of being overweight and obese than the boys. MUAC and TSF can adequately predict overweight and obesity among the selected students.
Analysis of Body Mass Index (BMI) of 3 to 18-year-old boys in 6 cohorts
Journal of Human Sport and Exercise, 2015
Growth and maturation of children is a dynamic and complex biological process, influenced by both genetic and environmental factors. Children's growth pattern can change from time to time, therefore, it is necessary to investigate the state of children's somatic development repeatedly. According to a widely accepted and scientifically proven theory, children's growth and maturation status is a sensible indicator of the nutritional and health conditions of the general population. Thus, information about growth and development of children and youth mirrors the biological status and/or welfare of a population. The "Körmend Growth Study", a chain of repeated cross-sectional growth studies performed on children in the town of Körmend (Hungary) was one of the first realizations of this principle. Anthropological investigations have been performed in Körmend in every 10 years since 1958 in a systematic way. The data are prepared from groups of 1563 to 2867 boys in Körmend, between 1958 and 2008 at 10-year intervals. Body Mass Index (BMI) was introduced into the human biology practice for the statistical evaluation of nutritional status according to the suggestions of Keys and coworkers. Comparing distinct ten-year intervals from 1958 to 2008, a characteristic tendency of BMI can be observed in boys.

To investigate the relationship between stunting and overweight among 10-15-y-old children of the North West Province in South Africa. A single cross-sectional study design was used. The study formed part of the THUSA BANA project. The total study population of the THUSA BANA project comprised of 1257 randomly selected subjects, aged 10-15 y. Stunting was described as the height below the 5th percentile for age using the CDC standard percentiles. Furthermore, the definitions of overweight and obesity according to the International Obesity Task Force (IOTF) were used, where the cutoff points for body mass index (BMI) corresponds with the adult BMI of 25 and 30, respectively. Anthropometrical variables namely triceps (TSF) and subscapular skinfolds (SSF), waist circumference, weight, height and BMI of the 10-15-y-old subjects were analysed. Stunting was most prevalent in the rural areas (girls 23.7% and boys 26.7%) compared with urban areas (girls 11.6%, boys 17.1%). The odds ratio an...

International Journal of Environmental Research and Public Health
The problem of overweight and obesity among children and adolescents has now become a major public health challenge worldwide. The aim of this study was to assess the effect of age and gender on body composition components and anthropometric indices of children and adolescents aged 6–15 years; in addition, the study aimed to assess body composition indices in relation to BMI (Body Mass Index) levels. The study was conducted at the end of 2019 and in the first quarter of 2020 among 181 pupils attending primary schools. Waist circumference, hip circumference, body weight, and body height were measured. The collected data were used to calculate and then to analyse BMI, WHR (Waist-Hip Ratio), and WHtR (Waist to Height Ratio) indices. Body composition was determined with the use of the Bioelectrical Impedance Analysis (BIA). The analyses’ statistics were performed using IBM SPSS Statistics 24 and Excel. The statistical methods used included Chi2 tests of independence, one-factor analysis...
