From 1980 to 2013, the prevalence of overweight children increased by nearly 50 per cent. With more than 42 million overweight children around the world, childhood obesity is increasing. Luckily Rwanda currently does not have this problem. But if awareness is not created , it can be a problem sometime in future. With development comes stability and increased affluence, underlying factor for obesity in adults as well as children.
Obesity carries risk of many problems in children. The first problems to occur are usually emotional or psychological. These children are usually mocked by other children,, are unable to participate in active sports and games, hence feel depressed. Childhood obesity can lead to life-threatening conditions including diabetes, high blood pressure, heart disease, sleep problems, cancer and other disorders. Some of the other disorders that could occur are liver disease, early puberty, menarche, eating disorders such as anorexia and bulimia, skin infections, asthma and other respiratory problems. Overweight children are also more likely to grow up to be overweight adults. Obesity during adolescence has been found to increase mortality rates during adulthood.
A study has found that obese children have stiffening of blood vessels in neck, due to fat deposits and also have abnormal levels of cholesterol in blood, which is a risk factor both for stroke and heart attack. Children who are obese are more likely to grow up into obese adults. Thus, they are more at risk for adult health problems such as heart disease, type 2 diabetes, stroke, several types of cancer, and osteoarthritis
The greatest risk factor for child obesity is the obesity of parents. This may be related to family environment and genetics. Psychological factors, likes and dislikes of a child also influence increase in weight. Other factors include the increasing use of technology, increase in consumption of high calorie snacks, increase in portion size of meals, and the decrease in the physical activity of children. Studies have shown that children who spend more than 3 to 4 hours per day with electronic devices have higher risk of becoming obese.
Schools can play a large role in preventing childhood obesity by providing a safe and supporting environment with policies and practices that support healthy behavior. At home, parents can help prevent their children from becoming overweight by changing the family diet. They can encourage the child to be physically active and also exercise regularly.

If children were more actively mobile and less sedentary, the rate of obesity would decrease. Parents should recognize the signs and help prevent obesity in their off spring by appropriate life style changes.
There are no medications currently approved for the treatment of obesity in children. Drugs like sibutramine, metformin, can reduce appetite thus reducing amount of calories consumed.
