Large Doses of Vitamin D Fail to Increase 25-Hydroxyvitamin D Levels or to Alter Cardiovascular Risk Factors in Obese Adolescents: A Pilot Study
Vitamin D deficiency and cardiometabolic risk factors are common in obese adolescents. Observational studies demonstrate an inverse relationship among serum 25-hydroxyvitamin D (25OHD) and obesity, insulin resistance, and inflammatory cytokines. This pilot study explores if vitamin D supplementation could reduce serum concentrations of inflammatory cytokines (interleukin [IL] 6, IL-10, tumor necrosis factor α), adiponectin, lipids, hemoglobin A1C, and high-sensitivity C-reactive protein (hs-CRP).Adolescent Purchasing Behavior at McDonald's and Subway
To assess whether adolescents purchasing food at a restaurant marketed as “healthy” (Subway) purchase fewer calories than at a competing chain (McDonald's).An Internet Obesity Prevention Program for Adolescents

It was hypothesized that the addition of coping skills training to a health education and behavioral support program would further enhance health outcomes.
