Weight monitoring of older schoolchildren at selected primary schools
MURČO VIRŠÍKOVÁ, Klára
The thesis is focused on monitoring the weight of older schoolchildren in selected schools. Its goal is to evaluate the weights of older schoolchildren at the Elementary School in Lišov and at the Bishop's gymnasium in České Budějovice using percentile graphs. One of the sub-goals is to complete this finding with a survey of knowledge about the principles of rational nutrition. The theoretical part approaches the topic of overweight and obesity in general and specifically in children, as well as the principles of rational nutrition. The practical part focuses on evaluating the weights of the 7th and 9th grade pupils at ZŠ Lišov and 2nd and 4th grade pupils at BiGy. The survey itself took place in selected classes in February 2024. There were 27 pupils in each class. The answers from the knowledge part of the questionnaires are evaluated in the practical part. Questionnaire questions were closed with one correct answer. There were a total of ten questions and they related to knowledge about rational nutrition. The tenth question asked about the sugar content in drinks, and the answers were an example of whether and how carefully the respondents read food and drink labels. Set BMI values were evaluated using percentile graphs. At primary school, the results were worse, where in the 7th grade only 37 % of respondents were in the category with a healthy weight and in the 9th grade even only 30 %. For gymnasium students, it was 59 % in the 2nd and 45 % in the 4th grade, and there was not a single respondent suffering from obesity in any of the classes. Based on the results found, it can be concluded that the pupils at the gymnasium don't have the same problems with overweight and obesity as the pupils at primary school. The biggest difference was noted between the 7th graders and the 2nd graders, when among the gymnasium there was not a single obese student and only one overweight student, while at primary school there were a total of 8 students in these two categories. Only the influence of the attended school on weight and the BMI was proven, while the influence of the pupils' age was not proven. The difference was also visible in the knowledge part of the questionnaire, regarding knowledge about rational nutrition. The knowledge of gymnasium students was 20 % better. At the gymnasium, the pupils had an average of 72 % of the correct answers, and at primary school it was only 52 %.
