Wellness Committee Status and Local Wellness Policy Implementation Over Time

Area of Science:

• Public Health
• School Health Policy
• Health Promotion

Background:

• Local Wellness Policies (LWPs) are critical for promoting nutrition and physical activity in schools.
• Previous studies suggest a link between wellness committees and LWP implementation, but longitudinal data is limited.

Purpose of the Study:

• To examine the association between the presence and continuity of school wellness committees over time and changes in Local Wellness Policy implementation.

Main Methods:

• A prospective cohort study using biennial statewide surveys from 2012-2013 (Wave I) and 2014-2015 (Wave II).
• School administrators reported on LWP implementation using a 17-item scale and wellness committee status (established, new, discontinued, never).
• Linear mixed models were used to analyze changes in LWP implementation across committee status groups.

Main Results:

• Schools with established wellness committees consistently showed higher LWP implementation compared to those without.
• New wellness committees were associated with a significant increase in LWP implementation, while discontinued committees led to a decrease.
• Schools with no committees maintained low implementation levels over the study period.

Conclusions:

• The formation and sustained presence of school wellness committees are strongly associated with enhanced Local Wellness Policy implementation.
• Recommending the establishment and maintenance of wellness committees is a viable strategy for improving school wellness environments.
