(HealthDay News) — Teens who were depressed as children are more likely to be obese, to smoke and to be sedentary, a new study finds.
The findings suggest that depression during childhood can increase the risk of heart problems later in life, according to the researchers.
The study included more than 500 children who were followed from ages 9 to 16. There were three groups: those diagnosed with depression as children, their depression-free siblings and a control group of unrelated youngsters with no history of depression.
Twenty-two percent of the kids who were depressed at age 9 were obese at age 16, the study found. “Only 17 percent of their siblings were obese, and the obesity rate was 11 percent in the unrelated children who never had been depressed,” study first author Robert Carney, a professor of psychiatry at Washington University School of Medicine in St. Louis, said in a university news release.
The researchers found similar patterns when they looked at smoking and physical activity.
