- Brief summaryThis study proposal aims to observe the effect of the theme certificates ‘Nutrition’ and ‘Exercise and Sport’ on the level of Advanced Glycation Endproducts (AGEs) in the skin of children aged 9 – 12 years when compared to regular education(no certificate). AGEs can be formed inside the body, when a sugar links to an amino group. AGEs also enter the body with food products. When someone consumes food products with a lot of added sugar, that person will have an increased production and accumulation of AGEs in the body. The amount of AGEs in a food product mainly depends on the preparation of the food product. When a food product is baked, fried or grilled, it contains more AGEs compared to the boiled, steamed or cooked version of the same food product. AGEs activate Receptors for AGEs (RAGE), which results in signaling mechanisms that cause cell stress, and contribute to cellular dysfunction, which leads to damaged target organs and complications. Exercise has been shown to diminish concentrations of circulating AGEs. AGEs are slowly transformed and broken down and changes in AGEs most probably will not be seen within a three month lifestyle change. It has been demonstrated that aerobic exercise improves insulin resistance in children, adolescents and adults, which may explain reduced levels of AGEs. The amount of AGEs can be measured by use of spectrophotometry. A recent portable advanced spectrophotometer called the AGE Reader has been developed that measures AGEs accumulated in the skin. In this study, the AGEs in the skin of the forearm will be measured. Besides, a questionnaire will be used to collect information about diet and exercise habits, anthropometric measurements will be done, and a cognitive test will be administered. Three primary schools are needed: one with the theme certificate ‘Nutrition’, one with the theme certificate ‘Exercise and Sport’ and one school without a theme certificate and serves as a control group. Each school has to supply 21 children for a reliable result according to the power analysis. The expectation is that the children who attend a primary school with one of the theme certificates, have a lower score on the AGE Reader when compared to the control school. The children of the primary school with the theme certificate ‘Exercise and Sport’ will probably score even better than the children from the school with the theme certificate ‘Nutrition’.
