What this trial studies

This study evaluates the effectiveness of a lifestyle intervention that combines motivational interviewing and a mobile app to help overweight women and their partners adopt healthier habits before conception. It aims to improve diet quality and monitor changes in weight, waist circumference, and body fat. Participants will be followed through pregnancy to assess the intervention's impact on gestational weight gain, pregnancy complications, delivery methods, and infant birth weight. The study addresses the critical need for early intervention to prevent obesity-related complications in pregnancy.

Who should consider this trial

Good fit: Ideal candidates are overweight women with a BMI of 25 kg/m2 or higher who wish to conceive within the next 12 months, along with their partners.

Not a fit: Patients with a personal history of infertility, diabetes, or other medical contraindications to pregnancy or physical activity may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could lead to healthier pregnancies and better outcomes for both mothers and infants.

How similar studies have performed: Other studies have shown promise in lifestyle interventions for overweight women, but this specific approach targeting the preconception period is relatively novel.
