Study on Out of School Nutrition and Physical Activity Environments (OSNAP)

July 15, 2011 updated by: Harvard School of Public Health (HSPH)
The purpose of this study is to design and conduct research to tailor out of school time evaluation materials so they are applicable to various settings in Boston, are efficient in that minimal resources and time are used, and are useful to participants.

Detailed Description

Nearly half of Boston's school age children (49%) participate in out of school time programs, a critical time to intervene on physical activity and nutrition. Previous research has mostly focused on during-school-day efforts, or on child care policies and practices for very young children, leaving a gap in the knowledge of what might work with programs serving school-age children during out of school time. OSNAP aims to implement low cost and sustainable policy and environmental interventions to improve physical activity and healthy eating/beverage environments. Data will be collected via observations, plate waste and accelerometers on program policies, environments, practices and behavioral outcomes related to physical activity, beverage, snack and screen time outcomes.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: control
Experimental: Policy and Environmental Change
Behavioral: Policy and Environmental Change
Afterschool programs participate in an assessment of physical activity and nutrition practices and policies. Study staff work with teams of afterschool programs in a participatory manner to identify areas in which programs would like to take practice, policy and communication efforts to meet physical activity and nutrition goals. Teams share progress and barriers during ongoing collaborative meetings.
