A randomized control trial: training program of university students as health promoters.

Background: Several studies have reported the following as determining factors for the adoption of healthy lifestyles among undergraduate students: gender, socioeconomic level, prior lifestyles, environment, parental lifestyles and health status, career choice, and healthy support networks. However, these factors are influenced by students' knowledge about healthy lifestyles.

Methods/design: We will carry out a randomized trial in a sample of 280 new undergraduate students at the National Autonomous University of Mexico's Faculty of Higher Studies-Zaragoza (FES-Zaragoza, UNAM).
