Overgewicht en obesitas bij kinderen en adolescenten en preventieve maatregelen

The prevalence of overweight and obesity in children is increasing rapidly. This is alarming because obesity is associated with severe chronic diseases, such as type 2 diabetes mellitus. Obesity at young age is related to obesity at adult age. Consequently, the prevention of overweight from childhood onwards is an important issue. Apart from diabetes mellitus type 2 there is an increased risk of orthopaedic complications, respiratory problems, fertility problems, cardiovascular diseases and psychosocial consequences in the form of a negative self-image, emotional and behavioural problems and depression. Environmental and behavioural factors are regarded as the most important causes of the rapid increase in the prevalence of overweight and as the most important starting points for prevention. Most prevention programmes are still in the initial stages. Prevention programmes aimed at stimulating breast feeding and daily physical activity (playing outside) and the restriction of sweetened drinks and watching TV are very promising. With such preventive measures the involvement of both the school and the parents is important.
