Plain English Summary
Background and study aims
Predimed-plus is a study that will measure how successful an intensive weight-loss lifestyle intervention involving an energy-restricted (calorie controlled) Mediterranean diet (Mediet), promotion of physical activity and behavioral support (intervention group) is compared to a less intensive intervention (control group) also involving a Mediterranean diet but no energy restrictions and no lifestyle or physical activity programmes. The aim is to see whether the more intensive intervention is more likely to result in long-term weight-loss, a reduced risk of developing cardiovascular disease and a greater quality of life for older people with metabolic syndrome (the medical term for the combination of diabetes, high blood pressure and obesity) than when adopting the Mediterranean diet alone.
Who can participate?
Men aged 55 to 75 years and women aged 60-75 years with a body mass index (BMI) ≥27 to <40 kg/m2, no cardiovascular disease and with metabolic syndrome.
What does the study involve?
Participants are randomly allocated into one of two groups. The low-intensity intervention group are given a non-energy restricted Mediet. The intensive intervention group are given an energy-restricted Mediet, physical activity and behavioral support and weight loss goals. Changes in body weight or any event of cardiovascular disease is recorded once a year, as well as other variables of lifestyle, educational achievement, history of illnesses, medication use, physical activity, dietary habits, and electrocardiography, blood pressure, and anthropometric measurements, neuropsychological and quality of life evaluations, and collection of fasting blood samples and morning spot urine.
What are the possible benefits and risks of participating?

Scientific title | Cardiovascular effect of an intensive weight-loss lifestyle intervention based on an energy-restricted traditional Mediterranean diet (Mediet) together promotion of physical activity and behavioral support in comparison with a less intensive program using Mediet, but without energy restriction or other lifestyle changes: a randomized field trial |
Study acronym | PREDIMED-Plus |
Study hypothesis | An intensive lifestyle intervention with an energy-restricted Mediet, promotion of physical activity, and behavioral support in comparison with Mediet alone, without other lifestyle changes, will reduce the risk of major cardiovascular outcomes (myocardial infarction, stroke, and cardiovascular mortality), be effective for weight loss and long-term weight-loss maintenance, and improve quality of life in older individuals with metabolic syndrome. |
Ethics approval(s) | Institutional Review Board of all participating centers |
Condition | Cardiovascular disease |
Intervention | Participants are randomly assigned into two equal groups: 1. Low-intensity intervention with a 14-item Mediet (with supplemental extra-virgin olive oil and tree nuts given at no cost for the participant) without energy-restriction, without weight loss goals and without a physical activity program. 2. Intensive intervention with an energy-restricted Mediet (with supplemental extra-virgin olive oil and tree nuts given at no cost for the participant) together with promotion of physical activity, behavioral support and weight loss goals. All participants will follow a 4-week run-in period to ensure compliance with the protocol. If compliant, they will be randomly allocated to one of the 2 interventions. Added 04/06/2018: Each recruiting center randomly assigned candidates in a 1:1 ratio to either the intervention or the control group. Randomisation was performed using a centrally controlled, computer-generated random-number internet-based system with stratification by center, sex, and age categories (<65, 65-70, >70-years) and using blocks of 6 participants. Couples living in the same household who both met eligibility criteria were randomized together as clusters. Consequently the second member of each household was not individually randomised. In the specific cases of couples in which the spouse was recruited at different times, the last spouse entering the study was assigned (not randomised) to the same study arm than his/her partner. |

IPD sharing plan | The datasets generated and analyzed during the current study are not expected to be made available outside the core research group, as neither participants’ consent forms or ethics approval included permission for open access. However, the researchers will follow a controlled data sharing collaboration model, as in the informed consent participants agreed with a controlled collaboration with other investigators for research related to the project’s aims. Therefore, investigators who are interested in this study can contact the PREDIMED Plus Steering Committee by sending a request letter to predimed_plus_scommittee@googlegroups.com. A data sharing agreement indicating the characteristics of the collaboration and data management will be completed for the proposals that are approved by the Steering Committee. |
