Intervention Effects on Health Promoting Behaviors and Factors Influencing Long-Term Behavior Change

Summary

This study aims to compare the 8-week virtual Healthy YOU Program with a standard care intervention that sends weekly nutrition and healthy living tips via email. It will evaluate short- and long-term changes in health behaviors, such as diet, physical activity, biomarkers, and body composition. The study also seeks to identify factors that help participants make lasting health changes and explore how lifestyle interventions can improve overall health. Findings may guide future programs and support non-weight-focused approaches to chronic disease management and healthcare policy.

Interventions

BEHAVIORAL

An 8-week virtual group intervention designed to promote sustainable health behavior changes in participants

The Healthy YOU Program is an 8-week virtual group intervention designed to help participants make lasting health behavior changes, focusing on diet and physical activity. Delivered via confidential Zoom sessions, it offers flexibility and support in a group setting. Participants engage in facilitated discussions, interactive activities, and expert guidance. Participants receive a structured curriculum with a printed workbook, covering evidence-based topics like nutrition, exercise, and well-being. Learning methods include: Weekly Newsletters: Provide health tips, resources, and reflections to support behavior change. Facilitated Group Discussions: Live sessions to share experiences, ask questions, and support each other. Applied Activities: Hands-on tasks like meal planning and goal-setting to build confidence. Demonstrations: Live sessions on healthy cooking, home exercises, and overcoming barriers. The program encourages goal setting, progress tracking, and self-regulation.

BEHAVIORAL

Standard of care Nutritional Information

The standard of care will involve providing participants with 8 weeks of nutrition information through printed handouts. These handouts will be generic, similar to materials typically provided by healthcare providers or available on public-facing health/nutrition websites. While they will cover the same topics as the experimental group, the handouts will contain only basic, publicly available nutritional information and will not include guidance for application. These handouts are also included in the Healthy YOU curriculum as background material for weekly class preparation. Participants will be instructed to review and utilize the handout information in a self-paced manner over the 8-week period.
