About this study
Official title: Effect of an Atlantic Diet on Anthropometric Indices and Serum Lipid Profile in a General Population: a Randomised Controlled Trial
BACKGROUND:
The Southern European Atlantic Diet (SEAD) is the traditional diet of Northern Portugal and Galicia, a region in northwest Spain. The SEAD has been associated with a lower risk of non-fatal acute myocardial infarction. Possible mechanisms of this association may be related with a lower concentration of markers of inflammation and with reduced triglycerides, insulin, insulin resistance, and systolic blood pressure.

Aim: To evaluate the effect of an Atlantic Diet on i) lipid profile, ii) markers of inflammation, and iii) anthropometric indices in a population-based study
METHODS:
This is a non-pharmacological clinical trial study which is performed on a family-oriented basis. 250 families (~ 750 children and adults, older than 3 years) were selected to participate in the study and randomized into Atlantic Diet (AD) (n=125 families) and control (n=125 families) groups. The AD groups participate in a diet program 1 day a month for 3 months in 120-minute diet sessions and freely receive AD food, characterized by a high intake of vegetables, cheese, olive oil, mussels and by wine consumption during meals. Control group subjects do not participate in any regular diet activity during this period and did not receive additional food. Exclusion criteria are alcoholism, lipid treatment, dementia, and terminal disease.
Weight, BMI, waist circumference (WC), skin folds, nutrient intake from 3-day recalls, food frequency questionnaire, physical activity, blood pressure, metabolic function (fasting blood glucose, HBA1c, insulin resistance and lipid profile), and inflammation markers (c-reactive protein, interleukin 6 and tumor necrosis factor-alpha) are measured at baseline, 3 and 6 months. Mixed effect models will be performed to assess the significance of changes in the cardiometabolic parameters.
The primary end point is the change in lipid profile compared with baseline and the control group arm at the end of Month 6. The secondary exploratory end points were change in anthropometric indices and inflammation markers at Month 6.
Read the detailed description
The intervention period lasted 6 months. At the baseline visit all AD subjects received information on the Atlantic diet and how to follow it; the nutritionists' messages were adapted to the clinical condition of each subject, his/her preferences, needs, beliefs and culture. Special care was taken with patients who were obese, had diabetes or who had high blood cholesterol; conflicts with recommendations made by subjects' own doctors or nutritionists were avoided. All questionnaires (see below) were filled out in the presence of the nutritionists, except for 3-day food records which the subjects handed in completed. The latter were reviewed in the presence of the subjects in order to correct any errors or add missing information. At the 3 and 6 month visits, the nutritionists reminded the subjects about the Atlantic diet and the helped them complete their questionnaires.
Foods were provided to the families of the AD group. Wine was provided only to non-tee-total adults. Food packages were delivered every three weeks to the family home. The food included in the package was calculated for the total number of family members, even if not all were taking part in the study. At delivery, a form was filled in to verify that the previous lot of food had been consumed, and to note any problems.

What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Total-cholesterol Levels
Change from baseline in total cholesterol:
Enzymatic method using standard kits on an Advia 2400 Clinical Chemistry System (Siemens Healthcare Diagnostics) [Time Frame: 6 months ]
Measured: baseline and 6 months
Secondary outcomes (4)
Change From Baseline in Body Weight
Measurements will be made in triplicate and recorded by standard methods using a SECA 813 digital balance with the subjects in underwear and barefoot. Body weight will be measured to the nearest 0.1 kg.
Measured: Baseline and 6 months
Change From Baseline in Body Mass Index (BMI)
BMI will be calculated as body weight (kg) divided by height (m) squared. The BMI of subjects under 18 years of age will be standardised using World Health Organization (WHO) reference data.
Measured: Baseline and 6 months
Change From Baseline in Hip/Waist Index
Waist circumference will be measured at the narrowest point between the bottom rib and the top of the iliac crest using a SECA 201 flexible, non-elastic tape.
Hip circumference will be measured at the point of greatest prominence of the gluteal muscles using a SECA 201 flexible, non-elastic tape.
Measured: Baseline and 6 months

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?
Yes. Results are posted in the registry (first posted 14 Apr 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in Total-cholesterol Levels (time frame: baseline and 6 months). 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 NCT02391701, which also lists 2 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 5 May 2020; AzTrials last refreshed its copy on 7 Nov 2026.
