From The New York Times By Jane E. Brody: Overweight children are likely to become overweight adults – unless they adopt healthier patterns of eating and exercise.
Life-threatening ailments like heart disease, cancer, stroke and Type 2 diabetes most often afflict adults. But they are often consequences of childhood obesity.
Two new studies, conducted among more than half a million children in Denmark who were followed for many years, linked a high body mass index in children to an increased risk of developing colon cancer and suffering an early stroke as adults. The studies, presented at the European Obesity Summit in Gothenburg, Sweden, this spring, underscore the importance of preventing and reversing undue weight gain in young children and teenagers.
One study, of more than 257,623 people, by Dr. Britt Wang Jensen and colleagues at the Institute of Preventive Medicine, in Bispebjerg, Denmark, and Frederiksberg Hospital in Copenhagen, grouped children according to standard deviations from a mean B.M.I., adjusted for a child’s age and sex.
They found that each unit of increase in being overweight at age 13, generally corresponding to a two- to three-point increase in B.M.I., increased the risk of developing colon cancer by 9 percent and rectal cancer by 11 percent.
The second study, involving 307,677 Danish people born from 1930 to 1987, used a similar grouping of B.M.I. The risk of developing a clot-related stroke in early adult life increased by 26 percent in women and 21 percent in men for each unit of increase in being overweight at all stages of childhood, but especially at age 13.
