Childhood Body-Mass Index and the Risk of Coronary Heart Di... In this Danish study, body-mass index in childhood was associated with coronary heart disease (CHD) events in adulthood. The association was stronger in boys than in girls, and the risk of an event in adulthood increased in both sexes as the child's age increased from 7 to 13 years. These important data focus attention on the public health significance of the epidemic of childhood obesity.
Adolescent Overweight and Future Adult Coronary Heart Disease Obesity, which is increasingly common among adolescents, is a risk factor for coronary heart disease (CHD). In this report, modeling the effects of overweight and obesity in adolescents on the risk of future CHD projects a substantial increase in the number of cases in the future.
