Shopping Smart - Adolescent Intervention to Improve Shopping Practices Where You Live and Learn
Condition: Food Choices
Study type: Interventional

Summary: 
      The objective of this project is to develop and test the effectiveness of a Cooperative
      Extension enhanced intervention titled "Smart Shopping," aimed at improving the shopping
      practices of adolescents with the ultimate goal of increasing fruit and vegetable intake. To
      achieve this goal, the investigators will conduct formative research (Year 1) via a
      community-wide analysis of the school, home and neighborhood food environments. In
      collaboration with Extension staff and faculty, this formative research will provide insight
      into the development and enhancement of the "Smart Shopping" curriculum (adapted from the
      "Cooking Matters" Extension curriculum, Year 2). In Years 3-4, the investigators will
      implement a randomized controlled intervention trial to examine the effectiveness of the
      developed intervention "Smart Shopping" to improve adolescents' purchasing and consumption
      behaviors. The investigators will implement the trial in Year 3, and evaluate results in Year
      4. Our education component will include training of University dietetics interns, graduate,
      and undergraduate students to implement and evaluate the intervention with oversight by
      project staff as part of their service learning requirements. This project is unique as it:
      1) takes into account the role that school wellness policies and school environment have in
      food procurement during the day; 2) incorporates information from multiple levels of the
      social ecological framework (home, school, and community food environments, as well as the
      social influence of peers) to create an intervention that addresses influences on adolescents
      purchasing and consumption behaviors where they live and learn; 3) collaborates with
      Extension faculty and staff while enhancing an existing program; 4) utilizes and hones the
      skill sets of students in undergraduate and graduate level nutrition and dietetics programs.
    

Detailed description: 
      Overview of the study - To achieve sustained healthy behavior changes, a supportive context
      is needed. For example, adolescents who are trying to consume more fruits and vegetables,
      fewer sugary beverages, and more water may be challenged in these pursuits as they may be
      inundated with low-cost, easily available, highly processed foods and beverages. The
      intervention will take into account the multiple sectors of influence on behavior among
      adolescents recently recommended. This project moves beyond understanding the interaction
      between the individual with their environment and seeks to develop and examine the
      effectiveness of an intervention aiming to improve how adolescents make healthy choices in a
      variety of food environments and in a variety of social settings.

      Overview - This project includes collection of primary data in Year 1 to inform the
      curriculum development of the "Smart Shopping" intervention in Years 2 and 3. The
      intervention will take place among 4 schools (2 in KY and 2 in NC) with 4 delayed - control
      schools (2 in KY and 2 NC). This individual-level intervention will be tailored based on the
      food environment factors of each site. The key food environmental variables that will be
      addressed will be school policy adoption and implementation of School Wellness Policies,
      availability of food within the home, as well as the availability and access to various food
      venues in each county. After baseline data are collected, the curriculum will be developed
      reflecting the shopping behaviors of adolescents in these counties. The curriculum will
      utilize current Cooperative Extension resources from "Cooking Matters," but will be tailored
      and significantly revised for adolescents using the formative data collected in year 1. The
      curriculum will be developed with Cooperative Extension agents in each county while
      connecting with dietetics and nutrition students. The intervention will take place over 12
      weeks, once a week, after school but before athletic or school sponsored activities begin.
      The intervention session will be led by nutrition and dietetics students, with oversight by
      Cooperative Extension agents and project team. Process evaluation will take place in year 2
      and 3 of the study, while main intervention outcome evaluation will take place in year 4 led
      by project team.
