Childhood obesity
Long-term effects

Children who are obese are likely to be obese as 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. A large population based study showed that adolescents who were overweight or obese had a 2.2 times increased risk of sudden death and a 3.5 times increased risk for death from coronary heart disease or stroke in adulthood as compared to normal BMI peers. Another study showed that those with an elevated BMI in childhood and adulthood were at an elevated risk of certain chronic medical conditions including a 5.4 times increased risk of diabetes, 2.7 times increased risk of hypertension, and 1.8 times increased risk of elevated LDL cholesterol (a cholesterol-based measure of risk of atherosclerosis) in adulthood. However, in children or adolescents with elevated BMI who reduce their BMI to normal levels, these risks are decreased to a similar level as those with normal BMI in childhood and adulthood. One study showed that children who became obese as early as age two were more likely to be obese as adults. According to an article in The New York Times, the health effects of childhood obesity may lead to a reduction in lifespan of two to five years. It is the first time in two centuries that the current generation of children in America may have a shorter lifespan than their parents.
