Summary
This summary is machine-generated.

The Strategies-To-Enhance-Practice (STEPs) intervention improved moderate-to-vigorous physical activity (MVPA) in afterschool programs. While not all children met the 30min/day MVPA goal, the program showed positive impacts on activity levels.

Area of Science:

  • Public Health
  • Pediatric Health
  • Behavioral Science

Background:

  • Afterschool programs (ASPs) aim for children (6-12 years) to achieve 30 minutes of moderate-to-vigorous physical activity (MVPA) daily.
  • Limited research exists on interventions to increase MVPA in ASP settings.

Purpose of the Study:

  • To evaluate the two-year impact of the Strategies-To-Enhance-Practice (STEPs) intervention on children's MVPA in US-based ASPs.
  • To assess the effectiveness of a multi-component intervention (programming, training, support) in helping ASPs meet the 30min/day MVPA standard.

Main Methods:

  • A two-year delayed treatment, group randomized controlled trial involving 20 ASPs in a southeastern US state.
  • Intervention focused on daily schedule integration, staff training, and ongoing technical assistance for MVPA.
  • Accelerometry measured the proportion of children meeting the 30min/day MVPA standard annually; mixed-model logistic regressions analyzed changes.

Main Results:

  • The intervention significantly increased the odds of boys in the immediate group achieving 30min MVPA/day (OR=1.88) and girls in the delayed group (OR=1.42).
  • Immediate girls and delayed boys showed non-significant increases in MVPA attainment.
  • Overall, the intervention demonstrated a positive impact but did not achieve the goal for all children.

Conclusions:

  • The STEPs intervention positively influenced children's MVPA and reduced sedentary time in ASPs.
  • Achieving the standard of all children accumulating 30min MVPA/day requires further strategies.
  • Continued efforts are necessary to identify effective methods for ASPs to meet this public health objective.
