Objective: To evaluate the acceptance and effectiveness of repetitive nutrition-related text messages on college students' nutrition knowledge and fruit and vegetable consumption.
Participants: One hundred fifty undergraduate (18-24 years old) non-health major students with a texting mobile phone.
Methods: The intervention group received biweekly text messages of the MyPlate icon and the United States Department of Agriculture's Dietary Guidelines (DGs) for 7 weeks. The control group received the same information in a mailed brochure. A pre and post online survey assessed the students' knowledge and behavior.
Results: The intervention resulted in greater MyPlate food group recognition (p <.05) compared with control and a trend toward improved knowledge of the DGs. In the intervention group, fruit consumption was elevated (p <.05) and a trend toward elevated vegetable consumption was determined. No gender differences in intervention effectiveness exist.
Conclusion: Texting repeated messages appears to be an acceptable and effective way to increase nutrition knowledge and promote positive diet-related behaviors in college students.
