“…Consistently with the literature, failure to meet the dietary goals was usually found among older participants [31,35], which may be explained because our participants had deeply rooted dietary habits and they were already fairly adherent to the MeDiet pattern at baseline [8,26].…”

Background: Determinants of dietary changes obtained with a nutritional intervention promoting the Mediterranean diet have been rarely evaluated.Aim of the study: To identify predictors of higher success of an intervention aimed to increase adherence to a Mediterranean diet (MeDiet) in individuals at high cardiovascular risk participating in a trial for primary prevention of cardiovascular disease: the PREDIMED (PREvención con DIeta MEDiterránea) trial. Candidate predictors included demographic and socioeconomic characteristics, cardiovascular risk-factors and baseline dietary habits.Methods: 1048 asymptomatic subjects aged 55-80 years allocated to the active intervention groups (subjects in the control group were excluded). Participants' characteristics were assessed at baseline among subjects. Dietary change were evaluated after 12 months. Main Outcome measures were: attained changes in 5 dietary goals: increases in 1) fruit consumption; 2) vegetable consumption, 3) monounsaturated fatty acid (MUFA)/ saturated fatty acid (SFA) ratio, and decreases in 4) sweets and pastries consumption, 5) and meat consumption. Univariate and multivariate logistic regression analyses were used to examine associations between the candidate predictors and likelihood of attaining optimum dietary change (improved adherence to a MeDiet).Results: Among men, positive changes toward better compliance with the MeDiet were more frequent among non-diabetics, and among those with worse dietary habits at baseline (higher consumption of meat, higher SFA intake, lower consumption of fruit and vegetables). Among women, marital status (married) and worse baseline dietary habits (high in meats, low in fruits and vegetables) were the strongest predictors of success in improving adherence to the MeDiet.Conclusions/ applications: Some participant characteristics (marital status, and baseline dietary habits) could contribute to predicting the likelihood of achieving dietary goals in interventions aimed to improve adherence to a MeDiet and may be useful for promoting individualized long-term dietary changes and improving the effectiveness of dietary counseling.

“…11 The MDP was defined according to an 'a priori' defined overall score previously used in the scientific literature. 4,[12][13][14][15][16] This score was calculated according to the tertile distribution for the consumption of several components of the Mediterranean diet. Eight of them were positively weighted (cereals, vegetables, fruits, legumes, fish, nuts, olive oil and moderate red wine consumption) and two others were negatively weighted (meat/meat products and whole-fat dairy products).…”

Adherence to a Mediterranean dietary pattern and weight gain in a follow-up study: the SUN cohort

et al. 2005

Introduction: The promotion of Mediterranean Diets has generated some doubts, because of the concern that its high fat content might lead to the development of obesity. Methods: Longitudinal analysis of 6319 participants in the SUN cohort study. We used a validated semiquantitative food frequency questionnaire (136 items). Baseline adherence to a Mediterranean dietary pattern (MDP) was assessed using a score (score_1) including vegetables, fruits, cereals, nuts, pulses, fish, olive oil and moderate consumption of red wine (positively weighted), whereas meat and dairy products were negatively weighted. We assessed the association between the overall baseline adherence to the MDP (score_1) and subsequent weight change after 28 months of follow-up. We also built another score (score_2) to assess changes in diet during follow-up and appraised the association between the joint exposure to both scores and weight change during follow-up. Results: Participants in the first quartile of score_1 (lowest baseline adherence to MDP) showed a higher weight gain ( þ 0.73 kg) than those in the top quartile ( þ 0.45 kg). The results indicated an inverse dose-response relationship (P for trend ¼ 0.016). A similar inverse association was apparent when we used change in adherence to the MDP (score_2). However, both inverse associations did not remain statistically significant after adjusting for relevant confounders. Consumption of dairy products was inversely associated with weight gain. Conclusions: Although participants increased their average weight during the follow-up period, weight increments were smaller among those with a higher adherence to an 'a priori' defined MDP. Results did not remain statistically significant after multivariate adjustment.

“…Recent nutritional surveys carried out in Spain also confirmed a progressive departure from the traditional Mediterranean diet towards a Western dietary pattern, mainly in young generations (5)(6)(7)(8)(9)(10)(11) . Because there is evidence that nutritional behaviours track from adolescence into adulthood, the promotion of healthy nutrition during adolescence has the potential to confer significant long-term health benefits (1) .…”
