Background: The aim of this paper is to investigate whether BMI and fat percentage classification criteria, would classify a sample in similar criteria’s. Methods: A cross-sectional study with a stratified random sampling included 602 rural boys (7–13 years old). Fat percentage criteria classification and BMI was measured Maturity, age and peak height velocity (PHV) were indirectly determined. Statistical techniques included descriptive, Pearson product correlation, 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 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 groups, with the exception of the eight-year old group which presented a moderate agreement. Conclusion: Classificat...

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....

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...
Background: Childhood obesity has reached the epidemic levels in developed and developing countries. Overweight and obesity have significant impact on both physical and psychological health. This study was cross-sectional that had been conducted in the period from August 2016 to March 2017 at six girls' basic schools at Khartoum locality. The main objective of this study was to identify the prevalence of general and central obesity among girls studying in basic schools at Khartoum locality, by using Body Mass Index for age (BMI) and waist to height ratio. Methodology: Sample size was 384 pupils from different schools girls aged between 10_ 15 years old. Data was collected by using questionnaire and anthropometric measurements of height, weight, waist circumference and waist to height ratio. Results: The result of study showed that, the prevalence of overweight and obesity was 20.3%. Regarding Waist to height ratio, 18 % of the girls had waist to height ratio less than 4, 67% had WHtR range between(0.4 _ < 0.5),13% had WHtR range between 0.5 _ < 0.6 and 2% had WHtR 0.6 and more. Those who exceed the normal WHtR were 15%. A significant relationship was detected between sport played by the pupils with BMI (0.005) and WHtR (P=.001). Conclusion: The results concluded that among the girl basic schools the prevalence of general obesity was 20.3% and central obesity was 15% and recommended more studies should be conducted among the pupils in basic school using the anthropometric indices..
Prevalence and determinants of overweight and obesity among school-aged children and adolescents
International Journal of Public Health Science (IJPHS)
Obesity is a significant public health crisis affecting millions of children globally. The objective of this study was to identify the prevalence and associated factors of overweight/obesity among school children in Kinshasa, Democratic Republic of Congo (DRC). This was a descriptive cross-sectional study among school children and adolescents (n= 1442) from Kinshasa selected using multistage sampling method. A structured questionnaire was used to collect behavioral data. The WHO AnthroPlus was used to calculate BMI (body mass index). SPSS version 21 was used for data analysis. Potential covariates were examined using chi-square tests followed by multivariate logistic regression analyzes The study found that out of 1442 students, 72% of the sample was at a healthy weight, 15% were underweight and nearly 13% were overweight or obese. The prevalence of overweight and obesity was higher in girls as compared with boys. The results of multivariate logistic regressions showed that the gend...
Prevalence of adolescent obesity at a high school in the City of Tshwane
Curationis
Background: Obesity has been reported to be on the rise in the world and South Africa is no exception. In recent years obesity has been reported to contribute to the increasing number of people with hypertension and diabetes mellitus. Africa has the fastest growing number of overweight and obese adolescents, with indications that in 2010, it had more than doubled since 1990. Some people might perceive being overweight as being round and healthy which might contribute to the increased rate of obesity in South Africa. Physical and psychological changes that occur during adolescence can also be observed earlier during the preteen years (ages 9–12 years). During this time, peer groups and external appearance are of importance. Physical changes, such as obesity, might be perceived negatively by adolescents, affecting their self-esteem.Objectives: The purpose of the study was to determine the prevalence of adolescent obesity at a high school in the City of Tshwane.Method: A cross-sectiona...

Objective To assess the use of mid-upper arm circumference (MUAC) for identification of overweight and overfatness in rural South African children and adolescents. Methods Anthropometric data (weight, height, MUAC and % body fat) from a cross-sectional sample of 978 black South African 5-14-year-olds were analysed. Receiver operating characteristic (ROC) curve analysis determined the validity of MUAC as a proxy for determining overweight and overfatness. Findings Area under the curve (AUC) results were generally high. Boys and girls aged 10-14 years had ROC-AUC for overfatness classed as 'excellent', 0.97 and 0.98 respectively. Cut-points in the MUAC distribution which optimised the ROC-AUC for identification of overfatness and obesity were determined for boys and girls aged 5-9 and 10-14 years, and had high sensitivity and specificity. Conclusions MUAC may have potential for clinical and surveillance applications as an accurate yet simple and widely available indicator of overweight and overfatness in children and adolescents in resource-poor settings.
A Study Of Prevalence And Determinants Of Obesity Among School Children
Overweight and Obesity represent a rapidly growing threat to populations' health in an increasing number of countries. Indeed they are now so common that they replace more traditional problems such as undernutrition and infectious diseases as the most significant causes of ill health. Childhood obesity is associated with a higher chance of obesity, premature death, and disability in adulthood. Hence, this study assessed the prevalence and determinants of Obesity among adolescent school children Methods: 1484 school children from private school In Nellore city participated in the study. A simple random sampling technique was used for sampling the study. Data was collected using a pre-designed and pre-tested questionnaire. Anthropometric measurements of height and weight were recorded. Data thus collected were analyzed using SPS statistical software, and the chi-square test was used as a test of significance. Results: The overall prevalence of overweight and obesity was 8.3%. Among the study participants, 52.2% were boys obese, and 47.8% were girls were obese. The significant risk factors include eating outside the home, eating while watching T.V., increased frequency of snacking outside, lack of outdoor sports, going to school on vehicles, prolonged school timings, long periods of watching/using the computer, no daily exercise, both parents working, fewer hours of physical training at school, and absence of playground in the school. Conclusion This study has identified some modifiable potential risk factors for overweight and obesity among school-age children. Understanding the risk factors for overweight and Obesity could help design effective preventive and control strategies targeted at some of these risk factors among this age group.
