The new maternal health questionnaire will help researchers understand factors affecting maternal health during pregnancy and their impact on lifelong wellbeing.
All volunteers are invited to take part because everyone has experienced being the baby of a pregnancy, and many have also been parents.
The survey includes questions on birth weight and maternal health issues during pregnancy.
Volunteers who have been pregnant will be asked additional questions about their own health during and after pregnancy, while those who have fathered a child will also have tailored questions.
Please note that some topics may be sensitive, including pregnancy-related health conditions and child loss.
All responses will play a vital role in supporting research aimed at improving care for families and future generations.
