The epidemic of childhood obesity continues to get worse.
A study in the journal Pediatrics finds rates of overweight children are increasing in all age groups.
Researchers say more than 41 percent of teenagers between ages 16 and 19 years old are obese.
For the first time in 10 years, the American Academy of Pediatrics has updated medical guidelines for treating adolescent depression.
The new recommendations include depression screening for children ages 12 and older.
And they suggest including family members in a teenager's mental health treatment.
As many as one in five adolescents experience depression.
One way to prevent depression could be with a healthier diet.
A study at Rush University found the foods that have been shown to reduce the risk of stroke may also reduce the risk of depression by as much as 11 percent.
The diet includes vegetables, fruit and whole grains, as well as low fat dairy products and cutting back on sugary foods.
