ASU Food Policy and Environment Research Group
A collection of scholarly work created by the ASU Food Policy and Environment Research Group under the leadership of Professor Punam Ohri-Vachaspati. The group examines policies, programs, and environments that influence food consumption and physical activity behaviors and health outcomes in disadvantaged populations. We aim to improve the health of children and families through comprehensive policy and environmental approaches.

Frequent consumption of fruits and vegetables has been linked to better dietary quality and positive health outcomes. Unfortunately, fruit and vegetable consumption among elementary school children falls far short of the recommendations. Therefore, finding strategies to promote fruit and vegetable consumption in children is a public health priority. One such strategy is the United States Department of Agriculture’s (USDA) Fresh Fruit and Vegetable Program (FFVP), which provides fresh fruits and vegetables as snacks, at least twice per week, in elementary schools with high student enrollment from low-income households. The program aims to expand the variety of fruits and vegetables children experience, impacting their present and future health outcomes. Another USDA initiative, the Supplemental Nutrition Assistance Program Education (SNAP-Ed), offered in community and school settings, aims to improve the likelihood that SNAP eligible individuals will make healthy food choices consistent with the Dietary Guidelines for Americans. SNAP-Ed is a potential resource for FFVP schools, providing nutrition education, staff training, and promotional materials.
Background
The transition from the home to college is a phase in which emerging adults shift toward more unhealthy eating and physical activity patterns, higher body mass indices, thus increasing risk of overweight/obesity. Currently, little is understood about how changing friendship networks shape weight gain behaviors. This paper describes the recruitment, data collection, and data analytic protocols for the SPARC (Social impact of Physical Activity and nutRition in College) study, a longitudinal examination of the mechanisms by which friends and friendship networks influence nutrition and physical activity behaviors and weight gain in the transition to college life.
Methods
The SPARC study aims to follow 1450 university freshmen from a large university over an academic year, collecting data on multiple aspects of friends and friendship networks. Integrating multiple types of data related to student lives, ecological momentary assessments (EMAs) are administered via a cell phone application, devilSPARC. EMAs collected in four 1-week periods (a total of 4 EMA waves) are integrated with linked data from web-based surveys and anthropometric measurements conducted at four times points (for a total of eight data collection periods including EMAs, separated by ~1 month). University databases will provide student card data, allowing integration of both time-dated data on food purchasing, use of physical activity venues, and geographical information system (GIS) locations of these activities relative to other students in their social networks.
Discussion
Findings are intended to guide the development of more effective interventions to enhance behaviors among college students that protect against weight gain during college.
