Gestational diabetes & diabetes in pregnancy
Factors impacting the recent doubling of French hyperglycaemia prevalence in pregnancy
Authors' conclusion
Rising maternal age, increased early HIP screening, and higher regional pre-pregnancy overweight prevalence mostly contributed to HIP prevalence increase. Public health strategies should prioritize modifiable risk factors-particularly pre-pregnancy overweight-and evaluate the effectiveness of early screening practices.
