It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Area of Science:

Public Health
Digital Health Interventions
Behavioral Science

Background:

College students are at risk for weight gain.
Digital interventions offer a scalable approach to health promotion.
Behavioral mediators like self-efficacy are key targets for weight management.

Purpose of the Study:

To pilot a digital interactive intervention for weight gain prevention in college students.
To assess the usability and acceptability of the intervention.
To evaluate changes in behavioral mediators related to healthy weight.

Main Methods:

A one-sample pre-post study design was employed.
Twenty college freshmen participated.
The digital program provided self-assessment and tailored feedback on 8 healthy weight-related behaviors.

Main Results:

Improvements in self-efficacy were observed for 5 behaviors.
Improvements in behavioral capability were noted for 3 behaviors.
The program demonstrated good acceptability, with 95% finding it relevant and 75% finding it easy to comprehend.

Conclusions:

The digital intervention is acceptable and shows promise in improving behavioral mediators for weight gain prevention.
Suggestions for enhancement include simplifying messaging and increasing user control.
Further testing in larger, diverse populations is recommended before widespread university adoption.
