Comparisons of school and home-packed lunches for fruit and vegetable dietary behaviours among school-aged youths.

Objective: School-based interventions and policies encourage youths to include and consume fruits and vegetables at lunchtime via school lunches, but limited research has examined how these behaviours compare when youths have home-packed lunches. The objective of the present study was to compare fruit and vegetable contents and consumption among students having school or home-packed lunches over the school week.

Design: Participants were observed over five consecutive days at school lunchtime.

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.

Feasibility and reliability of digital imaging for estimating food selection and consumption from students' packed lunches.

Although increasing attention is placed on the quality of foods in children's packed lunches, few studies have examined the capacity of observational methods to reliably determine both what is selected and consumed from these lunches. The objective of this project was to assess the feasibility and inter-rater reliability of digital imaging for determining selection and consumption from students' packed lunches, by adapting approaches previously applied to school lunches. Study 1 assessed feasibility and reliability of data collection among a sample of packed lunches (n = 155), while Study 2 further examined reliability in a larger sample of packed (n = 386) as well as school (n = 583) lunches.
