| Sumario: | Background: Non-time-consuming and easy-to-administer dietary assessment tools specific fi c for pregnancy are needed. Objectives: The aim of this validation study nested in the IMPACT BCN (Improving Mothers for a better PrenAtal Care Trial BarCeloNa) trial is to determine the concurrent validity of the 17-item pregnancy-adapted Mediterranean diet score (preg-MEDAS) and to analyze whether changes in the pregMEDAS score were associated with maternal favorable dietary and cardiometabolic changes after 3 mo of intervention in pregnant women. Methods: Dietary data was collected in 812 participants using the preg-MEDAS and a 151-item validated food frequency questionnaire (FFQ) at baseline (19-23 - 23 wk gestation) and fi nal visit (31-34 - 34 wk gestation). Concurrent preg-MEDAS validity was evaluated by Pearson and intraclass correlation coefficients, fi cients, kappa statistic, and Bland-Altman methods. Results: The preg-MEDAS had a good correlation with the FFQ (r r 1 / 4 0.76 and intraclass correlation coefficient i cient 0.75). The agreement of each of the pregMEDAS items ranged from 40.9% to 93.8% with a substantial agreement mean concordance (kappa 1 / 4 0.61). A 2-point increase in preg-MEDAS was associated with a decrease in maternal mean and systolic blood pressure (beta: -0.51 mmHg; 95% confidence fi dence interval [CI]: -0.97, -0.04 mmHg and -0.87 mmHg; 95% CI: -1.48, -0.26 mmHg, respectively). Conclusions: The preg-MEDAS displays good validity for assessing adherence to the Mediterranean diet, allowing detection of dietary changes over time. In addition, changes observed in preg-MEDAS are significantly fi cantly associated with a decrease in maternal blood pressure. Therefore, we propose pregMEDAS as a rapid and simple dietary assessment tool during pregnancy. |
