Prevalence of Overweight and Obesity in School Children in Bosnia and Herzegovina: A Cross-Sectional Study

Abstract

Purpose: To identify the characteristics of age groups of children from 10 to 14 years old in terms of the ratio of body weight and length, in particular, the relative number of children with overweight and obesity, and to develop recommendations for reducing body weight for children 10-14 years old. Material and Methods: An observational cross-sectional survey of the health status (overweight and obesity) of school children was conducted on sample 500 school children from Bosnia and Herzegovina (Republic Srpska entity), which included 246 boys and 254 girls, aged 10 to 14 years. Anthropometric data including Body height (BH), Body weight (BW) and age were collected from all elementary school children. Body mass index (BMI) is an anthropometric index of weight and height that is calculated by dividing a person's weight (kg) by the square of their height (m^2). BMI participants was estimated with the Percentile BMI calculator for children and teens aged 2-19 years. The studied children were defined as underweight, normal (healthy)-weight, overweight and obese according to the Center for Disease Control and Prevention (CDC) child growth characteristics for age, sex, and BMI. Basic central and dispersion parameters (Mean, Min., Max., Range, SD, CI 95%, CV%, Skew., Kurt.) were calculated for each variable. To confirm normality, the Kolmogorov-Smirnov test was applied (p>0.05). The homogeneity of variance was tested with Levene's test. The nutritional status of the subjects was assessed using percentile values on the basis of which the percentile categories are calculated. Statistical procedures and analyzes were performed using the statistical package STATISTICA 10.0 for Windows. Results: The dynamics of changes in the relative number of children with overweight and obesity from 10 to 14 years old was revealed. The lowest number of overweight and obese students was recorded at the age of 14 (1% <). The results of malnutrition in boys point to the conclusion that it is present in a smaller percentage, from 1.96% (age 14) to 6.12% (age 12). The largest number of girls at the age of 13 were overweight, 10 (19.23%) and obese (2%<), and then at the age of 10 and 11 (overweight 15.68% vs. 13.72%, and obesity 1.96% vs 3.92%). Malnutrition as a category is in a slightly higher percentage than for boys, ranging from 3.92% (11 and 12 years) to 7.84% (10 years). Conclusions: If a child is overweight at any age, this should be an alarming signal, as it can provoke weight gain in adulthood or with the slightest decrease in self-control. Therefore, the best strategy would be to create conditions for a child's development in which he will receive joy from other sources, and not just from food and activities that do not require physical activity. Finding even a relatively small number of overweight and obese children is not a benign problem. It requires its own solution, helping such children understand their problem and overcome it.
