Study Aim

This study aims to prevent unhealthy habits by evaluating the effectiveness of online and in-person training models for nutrition and physical activity practices in out-of-school settings, using the Out-of-School Nutrition and Physical Activity Observational Practice Assessment Tool (OSNAP-OPAT) to measure changes from baseline in goals met.

Study start date: September 1, 2016

Actual date on which the first participant was enrolled.

This study aims to find the best way to train staff in out-of-school programs to promote healthy eating and physical activity. The study focuses on YMCA programs across the country, specifically targeting 45 diverse sites. The goal is to help these programs make positive changes, such as offering healthier snacks, encouraging more physical activity, and limiting screen time. This research is important as it could lead to improved health and well-being for children attending these after-school programs. The study will compare two different training methods: online training and in-person 'train-the-trainer' sessions. These training methods will be tested against a control group that receives no training. Staff will be asked to use tools and resources from the Out-of-School Nutrition and Physical Activity (OSNAP) and Food & Fun After School programs to set goals and make changes in their programs. The success of the training methods will be measured using the OSNAP Observational Practice Assessment Tool, which assesses nutrition and physical activity practices. This tool will be used before and after the training to see if the programs have improved in meeting their health and activity goals.
