Introduction: Young adulthood is an important stage to establish dietary habits and lifestyle behaviors that could be linked to the long-term development of chronic diseases in later life. The 3 years follow-up prospective cohort DiSA-UMH study was set up with the main objectives of determining the nutritional status, lifestyle behaviors and health status, assessing the possible changes during the follow-up, and estimating their influence on the occurrence and development of chronic diseases.
Material and Methods: Baseline information of 1204 health science students from Universidad Miguel Hernández (UMH) aged between 17 and 35 years was collected during the period from 2006 to 2012. All the participants completed a general questionnaire divided into separate sections that included a food frequency questionnaire, specific questions on physical activity, tobacco consumption, nutritional labelling use, weight, height, health status, and questions about the diagnosis of several diseases. In order to validate self-reported data, several reliability/validity investigations with different subsamples were specifically conducted. After baseline questionnaire, students were asked to obtain anthropometric measurements and fasting blood samples. To evaluate our assessment of dietary intake, between three and nine 24-hour recalls administered by telephone were conducted over one year.
Results: The first follow-up period of 3-years finished in 2015 and the second 3-year follow-up period is still ongoing. Although the retention rates during these assessment periods were 59.2% and 52.2% respectively, the losses of follow-up happened in a random way because of characteristics of participants and non-participants during follow-up were similar.
