About this study
Official title: Effectiveness of a Personalized Intervention Program for the Promotion of the Mediterranean Diet, Based on a Mobile Phone Application (e12HR), in Students of the University of Seville
This is a controlled, randomized and multicentric clinical trial aimed at university students and performed at the Faculties of Medicine and Pharmacy at the University of Seville (Spain). Its objective is to evaluate the effect of an intervention based on the use of an information and communication technology (ICT) tool, specifically an application for mobile telephones (called e-12HR), in the improvement of adherence to the Mediterranean diet.
Read the detailed description
Objective:
To evaluate the effect of an intervention based on the use of an information and communication technology (ICT) tool, specifically an application for mobile telephones (called e-12HR), in the increased adherence to the Mediterranean diet in a population of university students.
Design and setting:
A controlled, randomized and multicentric clinical trial with two parallel groups (control group and intervention group).
Study population:
322 university students (161 participants in each group) are necessary; of both genders, over the age of 18 years, who meet selection criteria.
Study setting:
Faculties of Medicine and Pharmacy at the University of Seville (Spain).
Statistical Analysis Discrete variables are presented as a number followed by percentages. Continuous variables are presented using means and standard deviations.
The data are tested for normality using the nonparametric Kolmogorov-Smirnov test.
Students t-test or the nonparametric Mann-Whitney U-test is used for the analysis of quantitative variables, and the chi-square test is used for the comparison of proportions.
The results are considered significant if p-value < 0.05. Statistical analyses are performed using the SPSS statistical software package ver-sion 26.0 (SPSS Inc., Chicago, Illinois, USA).
Measurements and intervention:
Adherence to the Mediterranean diet is evaluated at seven (baseline), fourteen, twenty-one and twenty-eight days follow-up: the adherence to the Mediterranean diet index selected for the study is the Mediterranean Diet Serving Score (MDSS) index.
The advice on healthy diet recommendations (Mediterranean diet) is common to both groups.
There are two versions of e-12HR in the study: 'feedback' e-12HR and 'non-feedback' e-12HR (both versions of the application allow the collection of data on dietary intake in order to calculate the MDSS index).
Control group: use of 'non-feedback' e-12HR (in order to calculate the MDSS index).
Intervention group: use of 'feedback' e-12HR (in order to calculate the MDSS index; additionally, this version is designed to promote the Mediterranean diet).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
e-12HR appBehavioural
The 'feedback' e-12HR version: This version of the application allows to calculate the Mediterranean Diet Serving Score (MDSS) index; additionally, this version is designed to promote the Mediterranean diet with two specific automatic functions:
- Evaluation of the user's MDSS index.
- Identification of the food groups for which the user has not fulfilled the Mediterranean diet recommendations (in addition, this version also provided the user the consumption recommendations established for these food groups).
| Study group | Role | What they receive |
|---|---|---|
| Control group | No intervention | This arm uses the 'non-feedback' e-12HR. This version of the application allows to calculate the Mediterranean Diet Serving Score (MDSS) index. |
| Intervention group | Experimental | This arm uses the 'feedback' e-12HR. This version of the application allows to calculate the Mediterranean Diet Serving Score (MDSS) index; additionally, this version is designed to promote the Mediterranean diet. Receives: Behavioral: e-12HR app |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the total score of the Mediterranean Diet Serving Score (MDSS) index at fourteen days of monitoring in both arms.
Mediterranean Diet Serving Score (MDSS) index is a metric which provides an assessment of the degree to which individuals follow the Mediterranean diet. It took into account previously-established rules which consider: Specific food groups, recommendations for consumption frequency for standard servings (per meal, daily or weekly) and a numerical score assigned to each item.
Measured: To assess the effect of the intervention, the change in the total score of the Mediterranean Diet Serving Score (MDSS) index is calculated at fourteen days after the initial intervention in both arms.
Change in the total score of the Mediterranean Diet Serving Score (MDSS) index at twenty-one days of monitoring in both arms.

Questions about this trial
What is this clinical trial studying?
A study testing e-12HR app in people with Mediterranean Diet and Diet Habits, run by Luis María Béjar Prado at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 24 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Luis M Bejar, Doctor (34 600024248, lmbprado@us.es), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the total score of the Mediterranean Diet Serving Score (MDSS) index at fourteen days of monitoring in both arms. (time frame: To assess the effect of the intervention, the change in the total score of the Mediterranean Diet Serving Score (MDSS) index is calculated at fourteen days after the initial intervention in both arms.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05532137, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2024; AzTrials last refreshed its copy on 7 Nov 2026.
