Abstract
Trends in body mass index (BMI) among 51,889 14- to 20-year-old Icelandic adolescents and young adults were examined using data from cross-sectional population surveys conducted from 1992 to 2007. Prevalence of overweight increased for both genders in all age groups, except for 14- and 20-year-old girls. Obesity prevalence increased among boys in all age groups, except for 16-year-olds, and among 15- and 20-year-old girls. The largest increase in obesity rates among both genders was found in the oldest age group. Moreover, not only has the prevalence of obesity increased, but also the extent of obesity has grown more severe among 15- and 17-year-olds boys and among girls in the oldest age group.

Summary
The prevalence of overweight and obesity has increased among children, adolescents, and adults [1]. The onset of obesity is less associated with morbidity in adolescence and young adulthood, it is a strong determinant of obesity and affiliated morbidity later in life, with 50% to. Adolescent onset of overweight is associated with adult obesity-affiliated morbidity [7,8], independent of adult weight status [9]. From a public health perspective, monitoring the prevalence and trends in overweight and obesity among adolescents and young adults is of increasing importance. Adolescents and young adults who are overweight or obese are often burdened by decreased capacities for physical activity [10], but they may experience profound psychosocial complications that can affect their social interactions and school performance [11,12,13]
