Not applicable Interventional Universitaire Ziekenhuizen KU Leuven · NCT07270640

What this trial studies

This interventional project delivers a multi-component lifestyle program—nutrition guidance, tailored physical activity, and mindfulness—to people with dichorionic twin pregnancies recruited before 14 weeks' gestation. An initial integrated pilot phase will test feasibility and, if feasible, pilot participants will be rolled into the full study. The primary goal of the full study is to see if the intervention can extend gestational age at delivery by about one week, with secondary outcomes including pregnancy complications, maternal quality of life, and neonatal outcomes. Participants must be able to communicate in Dutch, English, or French and those with pre-existing conditions that limit diet or physical activity are excluded.

Who should consider this trial

Good fit: People pregnant with dichorionic twins enrolled before 14 weeks who speak Dutch, English, or French and do not have listed medical exclusions are the intended participants.

Not a fit: Those with pre-existing conditions that affect diet or physical activity (for example pre-gestational diabetes, severe heart or renal disease, celiac disease, COPD, severe asthma, neurological or musculoskeletal disorders) or those recruited after 14 weeks are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the intervention could prolong pregnancy by roughly one week and lower preterm birth rates, potentially improving neonatal health for twins.

How similar studies have performed: Lifestyle interventions have shown modest benefits in singleton pregnancies, but strong, replicated evidence in dichorionic twin pregnancies is limited, so this application is relatively novel.
