(HealthDay News) – Self-perceived overweight in normal-weight adolescents correlates with increased weight gain in early adulthood, according to a study published in the August issue of the Journal of Obesity.

Koenraad Cuypers, PhD, from the Norwegian University of Science and Technology in Levanger, and colleagues conducted a longitudinal study involving 1,196 normal-weight adolescents (13 to 19 years) to investigate the influence of self-perceived overweight on weight development in young adulthood (age 24 to 30 years).
