Adolescent overweight and obesity
JINDROVÁ, Kateřina
My bachelor´s thesis deal with obesity of adolescents and problems with overweight. These problems are described in details, and after that divided into specific parts. The main goal of my bachelor´s thesis is to chart problems with obesity and overweight in age group from 15 to 18 (adolescents) and primary describe their eating habits and physical activity. Theoretical part is focused on occurrence of overweight and obesity in the Czech Republic and in the world, causes of its origin, risk factors, classification and diagnosis, types, therapy and prevention. This bachelor´s work dealing with rational diet, describing basic principles of healthy catering and explaining right or wrong foodstuffs. I point mainly on prevention of overweight and obesity by healthy eating and physical activity. Methodical part is processed thanks to quantitative research. Data were gained by questionnaires, which were given to high school students (1st - 3rd grade). The research group contains 150 respondents from different schools in České Budějovice and close neighborhood. Final results are written down primary in graphs with commentary and data charts. In case of right use of qualitative research, there were determined two hypotheses. First hypothesis: Overweight and obesity is more occurred at adolescents with wrong eating habits. Second hypothesis: Overweight and obesity is more occurred at adolescents with low physical activity. For developing exploratory part, there was used quantitative research, which was provided by questionnaires given to students of age from 15 to 18. Entire data were processed by the use of program Microsoft Excel, and its calculations and functions. The answers of respondents were registered into database, and, by using specific excel functions, I was able to report data in determined categories. The research was mainly concentrated on physical activity and eating habits. Final results are put into well-arranged graphs, which are always enriched by comments, eventually completed by data tables, and, subsequently, statistically evaluated. In results, there might be seen two main differences between adolescents with standard weight and adolescents with overweight or obesity problems. One of those is irregularity in eating and wrong eating habits; big difference is also proved in physical activity. Adolescents with obesity or overweight have often irregular food intake, they drink a lot of high caloric beverages such as Coca-Cola, Sprite, Fanta etc., deficient income of fruit, vegetables, legumes, fish, or low physical activity. Only few of obese adolescents is different, because their problem is caused genetically. Adolescents with standard weight eat more regularly, but there are also some special cases, who have similarly wrong eating habits as obese people; however, all of these adolescents have one typical quality regular physical activity. Both hypotheses are confirmed. The results show that obesity is mainly caused by genetic predispositions, but these factors can be positively affected by periodic physical activity or appropriate eating habits. At the end of the thesis, it should be mentioned that it is necessary to be focused on right eating habits and regular physical from the very young age, when the basic customs and habits are assumed. That should include parents' action around their children, as they are usually the first example and they have the biggest influence.It is important to develop knowledge about all kinds of prevention, which are in most cases major in defending against formation of overweight and obesity.
