Advanced maternal age (≥35 years) is a strong, non-modifiable risk factor for GDM, with risk increasing linearly with age.

If you are over 35, be aware your risk for GDM is higher. Prioritize the lifestyle interventions (diet and exercise) mentioned earlier, as they are even more critical for this age group.
