Background and study aims
Lifestyle changes are the best way to prevent the main chronic diseases, through interventions that target sedentary lifestyle, eating habits, toxic habits and healthy sleeping. During the university period, changes in lifestyles may occur due to several factors: independence of the family home, coexistence with other students, the responsibility to decide what food to eat, the schedules, start or consolidation of toxic habits, and decreased physical activity. Therefore, this population group may be a risk group, which in the short or long term present risk factors related to the main chronic diseases. Because the University plays an important role in the acquisition and transmission of knowledge, this environment becomes an adequate space to carry out interventions to promote healthy lifestyles. Therefore, the aim of this study is to assess a lifestyle intervention in a sample of university students at the University of Valencia (Spain).
Who can participate?
University students aged 18 to 27 with at least two of the following: sedentary lifestyle, smoking habit, daily consumption of at least two energy drinks, number of daily sleep hours less than 7 hours or changes in their study shift
What does the study involve?
Participants are randomly allocated into two groups: the control group and the intervention group. The intervention group attend group and individual sessions focused on different aspects of lifestyle: healthy diet, physical activity, toxic habits, and sleeping. The education sessions are planned as follows: one group session of ten people per month and one individual session per month. No intervention is planned for the control group during the follow-up. The main lifestyle variables, including the profile of products consumed in vending machines, are assessed at the start of the study and after 3 months. In addition to the lifestyle questionnaires, body and blood pressure measurements are taken.
What are the possible benefits and risks of participating?
The participant will be notified of their risk factors and how to address them to improve their lifestyle and health. As this is an intervention study on lifestyles with scientifically proven recommendations that have been carried out for decades by different health organizations in the general population, no risks are foreseen.
