Abstract

OBJECTIVE: To assess the relation between adherence to a Mediterranean diet and the incidence of diabetes among initially healthy participants. DESIGN: Prospective cohort study with estimates of relative risk adjusted for sex, age, years of university education, total energy intake, body mass index, physical activity, sedentary habits, smoking, family history of diabetes, and personal history of hypertension. SETTING: Spanish university department. PARTICIPANTS: 13 380 Spanish university graduates without diabetes at baseline followed up for a median of 4.4 years. MAIN OUTCOME MEASURES: Dietary habits assessed at baseline with a validated 136 item food frequency questionnaire and scored on a nine point index. New cases of diabetes confirmed through medical reports and an additional detailed questionnaire posted to those who self reported a new diagnosis of diabetes by a doctor during follow-up. Confirmed cases of type 2 diabetes. RESULTS: Participants who adhered closely to a Mediterranean diet had a lower risk of diabetes. The incidence rate ratios adjusted for sex and age were 0.41 (95% confidence interval 0.19 to 0.87) for those with moderate adherence (score 3-6) and 0.17 (0.04 to 0.75) for those with the highest adherence (score 7-9) compared with those with low adherence (score <3). In the fully adjusted analyses the results were similar. A two point increase in the score was associated with a 35% relative reduction in the risk of diabetes (incidence rate ratio 0.65, 0.44 to 0.95), with a significant inverse linear trend (P=0.04) in the multivariate analysis. CONCLUSION: Adherence to a Mediterranean diet is associated with a reduced risk of diabetes.

  • Several population-based and prospective epidemiological studies have shown that adherence to the Mediterranean diet might have a protective effect against cardiovascular disease, stroke, obesity, diabetes, hypertension, several types of cancers, allergic diseases, and Alzheimer and Parkinson's disease.

    “Several population-based and prospective epidemiological studies have shown that adherence to the Mediterranean diet might have a protective effect against cardiovascular disease, stroke, obesity, diabetes, hypertension, several type of cancers, allergic diseases and, most recently, Alzheimer and Parkinson’s disease (7–18).”
  • Abundant intake of MUFAs or PUFAs with olive oil and seeds, in place of saturated or trans fatty acids, may reduce the risk of type 2 diabetes in at-risk patients by up to 83% over a median of 4.4 years, even in the absence of caloric restriction.

    “Moreover, the abundant intake of MUFAs or PUFAs with olive oil and seeds, in place of saturated or trans fatty acids, may also reduce the risk of T2D in at-risk patients by up to 83% over a median of 4.4 years [44], even in the absence of caloric-restriction [45].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
