Abstract

BACKGROUND: The traditional Mediterranean dietary pattern (MedDiet) is associated with longevity and low rates of cardiovascular disease (CVD). However, there is little information on who is more likely to follow this food pattern. AIM: To evaluate how different factors are associated with lower MedDiet adherence in older Spanish subjects. METHODS: We included 7305 participants (men aged 55-80 y, women 60-80 y) at high-risk of CVD recruited into the PREDIMED trial (ISRCTN35739639). Socioeconomic, anthropometric, lifestyle characteristics and CVD risk factors were recorded. A validated 14-item questionnaire was used to evaluate MedDiet adherence at baseline. Multivariate models were used to estimate odds ratios (OR) and 95% confidence intervals for lower adherence to the MedDiet (<9 points out of 14) and ascertain factors independently associated with it. RESULTS: Former smoking (OR = 0.87; 95% CI, 0.78-0.98), physical activity (OR for the 3(rd) vs. the 1(st)tertile: 0.69; 0.62-0.78), and higher educational level (OR for university vs. less than primary school: 0.54; 0.38-0.77) were associated with higher MedDiet adherence. Conversely, having a larger waist-to-height ratio (OR for 0.1 units, 1.35; 1.22-1.49), being diabetic (OR = 1.13; 1.03-1.24), being single (OR = 1.27; 1.01-1.61) or divorced or separated (OR = 1.44; 1.09-1.89), and current smoking (OR = 1.28; 1.11-1.47) were associated with lower adherence. CONCLUSIONS: Participants with little education, a larger waist-to-height ratio, or diabetes and those who were less physically active, single, divorced or separated, or smokers were less likely to adhere to the MedDiet, an ideal model for food choices. Stronger efforts of health promotion are needed in these groups to foster adoption of the MedDiet.

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.
