Effect of the Shaping Healthy Choices Program, a Multicomponent, School-Based Nutrition Intervention, on Physical Activity Intensity.

Objective: Physical activity has been shown to have a wide range of beneficial health effects, yet few youth meet the United States physical activity recommendation of 60 minutes of moderate-to-vigorous physical activity (MVPA) everyday. The objective of this study was to determine whether physical activity patterns improved in a subsample of fourth-graders participating in the multicomponent intervention, the Shaping Healthy Choices Program (SHCP).

Methods: At pre- and post-intervention assessments, youth at the control and intervention schools wore a Polar Active monitor on their nondominant wrist 24 h/d for at least 2 consecutive days.

Associations Among Fatty Acids, Desaturase and Elongase, and Insulin Resistance in Children.

Objectives: Fatty acid profiles and desaturase (SCD-16, SCD018, D5D, D6D) and elongase (ELOVL6) enzyme activity have been associated with adiposity and metabolic disease. While this has been studied in adults, few studies have included children. The objective of this study was to evaluate these markers in children and identify relationships with markers of metabolic health.
