Is this trial a fit for you?

Likely a good fit

Adult, French-speaking pregnant women (8–16 weeks gestation) with a singleton pregnancy and starting BMI 18.5–35 who can attend visits in Toulouse/Auch and be accompanied by a household member who shares at least one meal daily.

Probably not a fit

Women with pre-existing diabetes or gestational diabetes (by fasting glucose), prior bariatric surgery, eating disorders, metabolic or digestive conditions requiring special diets, recent >10% weight loss before pregnancy, those under legal guardianship, or those with BMI outside 18.5–35 are unlikely to benefit or are ineligible.

What this trial studies

This randomized controlled trial will assign pregnant women between 8 and 16 weeks' gestation to either family-based dietary monitoring, with a household member who shares at least one meal participating in counseling, or to standard individual dietetic counseling. The intervention focuses on meal planning, nutrition education, and ongoing monitoring of maternal diet to influence total gestational weight gain, with outcomes including maternal weight change and infant birth weight. Eligible participants are adults with singleton pregnancies, starting BMI 18.5–35, French-speaking, and affiliated with social security, while women with diabetes, prior bariatric surgery, eating disorders, certain metabolic or digestive conditions, or recent major weight loss are excluded. Study visits take place at participating centers in Toulouse and Auch, France.

Why it matters

Potential benefit: If successful, this approach could help pregnant women stay within recommended weight-gain ranges and may improve newborn weight outcomes.

How similar studies have gone: Previous partner- or family-supported nutrition interventions in pregnancy have produced mixed results on gestational weight gain, so this particular family-based monitoring approach is relatively novel.
