Biological correlates and predictors of insulin resistance among early adolescents.

Abnormal glucose metabolism is associated with obesity, insulin resistance (IR), and Type 2 diabetes mellitus. The purposes of this study were to describe anthropometric and laboratory markers of adolescents, examine correlates of IR, and test ability of anthropometric and laboratory markers to predict risk of exhibiting IR. A total of 150 early adolescents participated.

Relationship of weight status and cardiometabolic outcomes for adolescents in the TEAMS study.

The increase in the prevalence of obesity among youth is alarming. Relationships exist between excess weight and adverse cardiometabolic markers. The aims of this study among adolescents in the Teen Eating and Activity Mentoring in Schools (TEAMS) project were to describe selected demographic characteristics, anthropometric measurements, and laboratory values of middle school students; contrast differences in rates of cardiometabolic markers for participants with body mass index (BMI) ≥ 95th percentile and <95th percentile; examine rates of exceeding cardiometabolic cutoffs by weight status; and predict the odds ratio for one or more adverse cardiometabolic outcomes when BMI ≥95th percentile.

Obesity prevention in early adolescence: student, parent, and teacher views.

Background: Obesity is a significant health problem among today's youth; however, most school-based prevention programs in this area have had limited success. Focus groups were conducted with seventh- to eighth-grade students, parents, and teachers to provide insight into the development of a comprehensive program for the prevention of adolescent obesity: the Teen Eating and Activity Mentoring in Schools project (TEAMS).

Methods: Questions addressed (1) beliefs about the relationship between early adolescent behavior and health; (2) early adolescents' physical activity habits, preferences, influences, and barriers; (3) early adolescents' dietary habits, preferences, influences, and barriers; and (4) recommendations for interventions to promote physical activity and healthy eating in early adolescence.
