NUYou:mHealth Intervention to Preserve and Promote Ideal Cardiovascular Health

American Heart Association Strategically Focused Research Network: mHealth Intervention to Preserve and Promote Ideal Cardiovascular Health

The purpose of the study is to investigate the preservation or promotion of health in students during the college years.

Freshman college students at Northwestern University will be cluster randomized to two groups based on their dorm. The intervention for one group will target smoking, physical activity, BMI and consumption of fruits and vegetables. The intervention in the second group will target traveling behavior, sexual risk behaviors, sunscreen use and hydration. Baseline health and lifestyle measures will be assessed for each participant prior to intervention. Health assessments will measure height, weight, fasting glucose, total cholesterol and carbon monoxide. The lifestyle measure will ask questions about physical activity, diet, alcohol and tobacco use, safe sex practices, driving habits, and sunscreen use. These same measures will be repeated during the fall of the students' sophomore and junior years.

Participants will be given a mobile application and encouraged to track some behaviors. In addition, participants will be asked to answer weekly questions regarding health behaviors.
