What this trial studies

This clinical trial tests an enhanced version of the National Diabetes Prevention Program (NDPP-NextGen) specifically designed for young women aged 18-39 who are overweight or obese and likely to conceive within 24 months. Participants will be randomized into either the NDPP-NextGen group, which involves a 12-month online group class, or a usual care control group that receives general health information. The study aims to assess the program's effects on pre-pregnancy blood sugar levels, weight gain during pregnancy, and the infant's fat tissue percentage at birth. The trial addresses the critical need for early interventions to break the cycle of obesity and diabetes across generations.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-39 with a BMI of 25 or higher who are interested in conceiving within the next 24 months.

Not a fit: Patients who are currently pregnant or have non-gestational diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly reduce the risks of obesity and diabetes for both mothers and their future children.

How similar studies have performed: Previous studies have shown that lifestyle interventions like the NDPP can be effective, but this specific approach targeting preconception is relatively novel.
