Is this trial a fit for you?

Likely a good fit

Pregnant women aged over 18 with obesity and/or chronic or gestational hypertension or diabetes who can attend an in-person session are the ideal candidates.

Probably not a fit

Patients with preexisting cardiomyopathy, significant renal or pulmonary disease, active systemic infection, genetic syndromes, or type 1 diabetes are excluded and unlikely to receive benefit from this intervention.

What this trial studies

This pilot randomized controlled trial randomizes pregnant women with obesity and/or chronic or gestational hypertension or diabetes to a Mediterranean Diet education program or to standard hospital dietary care. The intervention consists of one face-to-face education session supported by a 13-page manual and five monthly newsletters sent by email to reinforce adherence. Outcomes include diet adherence and cardiometabolic measures, with a primary focus on cardiac reverse remodeling, glycemic and blood pressure control, postpartum weight recovery, and changes in the fecal microbiota. Secondary aims include observing any effects on exclusive breastfeeding and the timing of introducing complementary foods to infants.

Why it matters

Potential benefit: If successful, the program could improve mothers' cardiac and metabolic health after delivery and support healthier weight recovery and gut microbiota patterns.

How similar studies have gone: Mediterranean diet programs have improved cardiometabolic outcomes in other adult populations, but applying this approach to postpartum cardiac reverse remodeling is relatively novel and being piloted here.
