Eksperimentel: Immediate Intervention
Over the 3 year project, this arm receives the Healthy Eating and Physical Activity intervention after year 1 (baseline) for a total of 2 years (year 2 and 3).
|
Create partnerships with ASPs to help facilitate changes in programming to meet the National Afterschool Alliance's HEPA Standards.

Eksperimentel: Delayed Intervention
Over the 3 year project, this arm serves as the no treatment control/comparison group for year 1 and 2 (2 years of baseline) and receives the Healthy Eating and Physical Activity intervention in year 3 for a total of 1 year.

Change in Percentage of Children Meeting Physical Activity Policy
Tidsramme: Spring of Year 1, Year 2, and Year 3
|
We will assess the number of children meeting the physical activity policy of 30 minutes or more of moderate-to-vigorous physical activity.
The primary physical activity (PA) and sedentary behavior outcome was derived via accelerometry.
All children attending an ASP on unannounced measurement days had an opportunity to wear the ActiGraph GT3X+.
The accelerometers were distilled using 5-second epochs.
When children arrived to a program, they were fitted with an accelerometer and the arrival time was recorded (monitor time on).
Before a child departed from a program, research staff removed the belt and recorded the time of departure (monitor time off).
Children wore the monitors for their entire attendance at the ASPs.
Cutpoint thresholds associated with moderate and vigorous activity were used to distill the PA intensity levels and sedentary behavior.
Children were considered to have a valid day of accelerometer data if their total wear time (time off minus time on) was ≥60 minutes.

Changes in Nutritional Quality of Snacks
Tidsramme: Spring of Year 1, Year 2, and Year 3
|
We will assess quality of snacks served at the ASPs in terms of number of fruits and vegetables served per week.
These analyses were performed at the ASP level with a sample size of 20 (10 per arm)
