Samenvatting

Most people will be surprised when you tell that more than half of the adult population in South Africa is overweight or obese. Shockingly 25% of the females and 19,6% of the males is overweight and 40,1% of the females and 11,6% of the males is obese. A reason for this is the upcoming economy in South Africa which has led to more western habits where traditional high-fibre diets are replaced by diets high in fat and sugar.

Overweight and obesity are defined as excessive or abnormal fat accumulation that presents a risk to health. To draw attention to this problem and make people aware of the risks of overweight and obesity, a research and health promotion has been conducted at the Emil Weder High School in Genadendal, Western Cape. Of the total 580 learners, 310 learners have been measured for weight and height to calculate the BMI, and find out what the prevalence of overweight and obesity is at the High School..

Before conducting the research at the high school, a desk research has been carried out to find out if there are associations between certain eating and lifestyle habits and overweight and obesity. Also different methods have been analysed to see what is the best measurement for overweight and obesity among adolescents. After comparing the BMI, skinfold measurements and waist circumference, it shows that the BMI is the easiest, fastest and most common used method for children and adolescents.

A distinction is made between immediate causes, underlying causes and basic causes. Several studies found an association between stunting and the risks of developing overweight at a later stage.
This project will be focused on behaviour, which are the immediate causes, namely dietary intake and physical inactivity. The most important behaviours that were associated with overweight were the high consumption of sweet cool drinks and unhealthy snacking. This behaviour is stimulated by the environment such as the many fast food restaurants and Tuck Shops at school.

Overweight can lead to both physical and psychological problems. The most common physical problems as a result of overweight are chronic diseases such as diabetes, cardiovascular diseases and cancer.

The outcomes of the anthropometric research is comparable with desk research (19% - 19,7%). They also both confirm that there is a higher prevalence among females than males. When looking at the relation between overweight and purchasing unhealthy snacks from the Tuck Shop, 18,2% from all the learners that bought something from the Tuck Shop, is overweight or obese (15% female and 3,4% male). All the girls with obesity purchased something from the Tuck Shop the day before.

Based on the behaviours that were found in desk- and field research, an intervention is developed with the goal to prevent overweight and obesity by promoting healthy nutrition, improving the knowledge about healthy nutrition and creating awareness of the learners current lifestyle. The intervention consisted of two parts, where in the first part a poster competition was organized and in the second part a healthy lifestyle was promoted by selling healthy snacks and drinks. A lot of positive feedback was given by teachers, staff and supervisors about the healthy snacks and the factsheets. Unfortunately, an effect evaluation needs yet to occur. This is an important thing for in the future to see what improvements can be made to the intervention.

The questions that have been asked during the research were based on 24h-recall, which means that there is only information obtained from the day before the research. These questions have been asked to give an idea in which direction on can look to determine the actual behaviour of the learners. More research is needed to get more insight in the behaviours that is causing overweight and obesity and how to prevent this health problem.
