Abstract

Objective

To describe the research methods used for the Diet and Health Study, a pilot-feasibility study to assess the impact of a whole-food plant-based vegan diet on college students’ physical and mental health.

Design

This 3-week theory-based pilot-feasibility study will employ a stratified, randomized control design (2 intervention groups and 1 comparison group) with measurement of primary and secondary outcomes at baseline and postintervention and end-of-study focus groups.

Setting

Southeastern public state university.

Participants

Sixty undergraduate college students aged 18–25 years.

Intervention

The study and intervention delivery were designed using an integration of the Theory of Planned Behavior and Social Cognitive Theory. Three consecutive weekly nutrition education lunch-and-learn sessions (75 minutes each) will be delivered using 2 different teaching modalities (ie, interactive-experiential vs lecture-based).

Main Outcome Measures

(1) Feasibility and acceptability of study procedures and theoretically-informed whole-food plant-based vegan diet intervention; (2) potential impacts of the intervention on intrapersonal, physical, and mental health, and dietary measures; and (3) potential differential impacts of 2 intervention modalities.

Analysis

Descriptive statistics and effect sizes to assess changes to the outcome variables from baseline to postintervention across the 3 groups. Qualitative content analysis of the focus group transcripts.

期刊介绍： The Journal of Nutrition Education and Behavior (JNEB), the official journal of the Society for Nutrition Education and Behavior, is a refereed, scientific periodical that serves as a global resource for all professionals with an interest in nutrition education; nutrition and physical activity behavior theories and intervention outcomes; complementary and alternative medicine related to nutrition behaviors; food environment; food, nutrition, and physical activity communication strategies including technology; nutrition-related economics; food safety education; and scholarship of learning related to these areas. The purpose of JNEB is to document and disseminate original research and emerging issues and practices relevant to these areas worldwide. The Journal of Nutrition Education and Behavior welcomes evidence-based manuscripts that provide new insights and useful findings related to nutrition education research, practice and policy. The content areas of JNEB reflect the diverse interests in nutrition and physical activity related to public health, nutritional sciences, education, behavioral economics, family and consumer sciences, and eHealth, including the interests of community-based nutrition-practitioners. As the Society''s official journal, JNEB also includes policy statements, issue perspectives, position papers, and member communications.
