NCT ID NCT06402825
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study checks on children aged 6-10 whose mothers took part in a lifestyle program (diet and exercise coaching) before getting fertility treatments for obesity. Researchers want to see if these kids have healthier body measurements and blood markers compared to kids whose mothers had standard care. The goal is to learn if helping women before pregnancy can break the cycle of obesity passing from mother to child.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fit-for-Fertility program (dietitian and kinesiologist sessions, educational groups)
- What this could lead to
- If successful, this could show that helping women with obesity improve their lifestyle before pregnancy reduces the risk of childhood obesity and related health problems.
- What could go wrong
- This is a small follow-up study (35 children) and only looks at past data, so it cannot prove cause and effect. Results may not apply to other groups.

Who is studied
Children born from mothers who participated in the Obesity-Fertility study. Those mother were recruited between 2012 and 2018 at the fertility clinic of the Centre hospitalier universitaire de Sherbrooke. To be included in the study, they had to be aged between 18 and 40 years and living with infertility and obesity, or overweight if they had polycystic ovary syndrome (PCOS). Women were excluded if they had undergone or were planning bariatric surgery, or if natural conception was impossible or unlikely (such as both fallopian tubes blocked or severe male factor).
