Women who are overweight at the age of 18 have a greater chance of dying young.
A study of more than 100,000 female nurses demonstrated that those who were overweight or obese at 18 were more likely to die between the ages of 36 and 56. They also were likely to drink more alcohol and smoke more, and were less likely to exercise.
Women who were moderately overweight at 18 were more than half as likely to die young, and obese teens were more than twice as likely to die. Causes of death included cancer, heart disease, stroke and suicide.
One-third of children and teens in the United States -- 25 million total -- are either overweight or on the brink of becoming so, according to a recent government survey.
