[Changes in the physical activity of university students during the first three years of university].

Introduction: physical inactivity is the fourth most important risk factor for mortality worldwide and university students present this risk factor at a high level. Objective: to determine the changes in the physical activity of university students in Navarra during the first three years of college. Methods: prospective observational study of a cohort of university students. They participated in the first year, and two years later in the third year. The cohorts were comprised of 454 students who answered a voluntary and anonymous self-completion questionnaire with sociodemographic and physical activity related variables. Data were analyzed with SPSS v21.0. Results: of the participants, 67.4% (n = 306) were women and 32.6% (n = 148) were men. In the first year, 61.6% of students performed more than 150 minutes of physical activity per week. This percentage increased by 2.7%. The frequency of physical activity at least three times a week increased 6.1%, reaching 30.5% of students. Conclusions: university does not play a significant role in the promotion of physical activity, finding minimal modifications. In the future, it would be convenient to consider the reasons that hinder physical activity and design programs according to current recommendations.
