Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07903935). This is a study registration, not published results. Lead sponsor: Appalachian State University. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 39 participants (ACTUAL). Conditions: Healthy, College Students, Diet Interventions, Vegan Diet, Feasibility Pilot Study, Diet Quality, Lipid Profile, Depressive Symptoms. Interventions: OTHER: Interactive intervention group; OTHER: Lecture-based intervention. Primary outcome measures: Feasibility and Acceptability: Study Uptake , From enrollment through the first 10 days of the study, i.e., the last day to have enrolled, completed an online baseline survey, and completed a baseline biometric measurement session; Feasibility and Acceptability: Study Attrition , From enrollment to the end of the study at 6 weeks; Feasibility and Acceptability: Intervention Engagement , Weeks 3 through 5 of the study; Feasibility and Acceptability: Qualitative Assessment , At the end of the study, during week 6; Feasibility and Acceptability: Food Acceptability Questionnaire , At the end of the study, during week 6. Brief summary: The goal of this pilot randomized controlled trial (RCT) was to assess the feasibility, acceptability, and impacts of a whole-food plant-based (WFPB) vegan diet intervention for undergraduate university students randomly assigned, stratifying by sex and race/ethnicity, to one of two intervention groups (each with a distinct teaching-learning design, i.e., interactive (IA) versus lecture-based (LB)) and a control group. The main questions the researchers aimed to answer were: * Were the study procedures feasible and acceptable for the overall sample and were the intervention sessions, following a WFPB vegan diet, and the prospect of continuing this diet feasible and acceptable for the intervention participants? * Were there greater improvements in diet quality, WFPB vegan diet adherence, physical and mental health, and intrapersonal factor outcomes for the intervention group engaging in interactive learning compared to the intervention group learning through traditional lecture? And were there greater improvements in these outcomes for both intervention groups compared with the control group? The researchers compared the group outcome means for the two intervention groups against one another and those for the two intervention groups against those of the control group. Study participants completed two sets of measurements over the course of 6 weeks. * All participants completed online baseline and post-intervention surveys and in-person baseline and post-intervention biometric measurements. * Only the intervention group participants attended three 75-minute consecutive weekly intervention sessions to learn about different aspects of the WFPB vegan diet between the two sets of survey and biometric measurements.
