A new Australian study has pointed out that obesity rates go up between adolescence and young adulthood.
Between 1992 and 2003, Patton and colleagues tracked the height, weight and body mass index (BMI) of 1,520 teens, starting at age 14 and continuing through age 24.
By mid-adolescence, one in five teens was overweight, but by age 24, that proportion increased to one in three. Forty percent of overweight young adults had never even been overweight during the teens, the authors reported in the study.
The study appears in the latest issue of the Journal of Adolescent Health.
