| dc.description.abstract | The rising prevalence of obesity during women’s reproductive years highlights the need for effective strategies to improve nutritional literacy as a preventive approach to adverse postpartum outcomes. This pilot randomized controlled trial aims to evaluate the impact of nutritional education sessions promoting the Mediterranean Diet (MedDiet) on Mediterranean Diet Adherence Screener (MEDAS), preconception weight recovery, and cardiometabolic outcomes. A PERIMYR-OralBioBorn mother-infant birth cohort sub-sample with obesity, hypertension, and/or diabetes was randomized to receive a MedDiet intervention, that consisted of a face-to-face session using a 13-page manual, followed by five monthly newsletters. Participants were re-evaluated at one, and six months postpartum. To assess the adherence to the MedDiet, the 14-item questionnaire MEDAS validated for the Portuguese population was used. Cardiac function and structure during pregnancy and postpartum were evaluated by echocardiography. Statistical analyses included Chi-square tests, T-tests, and Mann-Whitney tests. RESULTS: Fifty-six women with cardiometabolic risk factors (obesity, diabetes, and/or hypertension), with a median age of 33 [30; 36.5] years in the third trimester of pregnancy, were included. No significant differences in MedDiet adherence scores were observed between control and intervention groups before the intervention (8.6±1.8 vs. 8.5±1.5, p=0.815). One month postpartum, both groups maintained moderate adherence (7.7±2.1 vs. 8.2±2.6, p=0.731), with no differences between groups at six months (7.4±1.9 vs. 8.1±2.3, p=0.466). The intervention did not affect preconception weight recovery at six months. However, the intervention group showed better cardiac relaxation (E/e’ ratio) than controls (5.7±1.4 vs. 6.6±1.4, p=0.042), with no differences in cardiac mass or left ventricle wall thickness regression 6 months postpartum. Although preliminary findings do not indicate a significant change in MedDiet adherence scores or weight recovery, we observed improved left ventricular diastolic function. Future research incorporating detailed dietary intake assessments, metabolic biomarkers, and physical activity tracking could help clarify these effects. | eng |
