Study details

C-GULL is a prospective, observational cohort study of 10,000 first-born infants and their parents (in triad design), nested within a population-wide, civic data linkage platform. As part of this initial phase, the study will collect extensive biological, biometric, socio-demographic and psychosocial information at two time points antenatally (12-16 weeks gestational age and 32-36 weeks gestational age), birth (delivery), and when the child is aged three, 12 and 24 months.

Pregnant people are eligible to take part in the study if this is their first ongoing pregnancy, their pregnancy is in the first 12-16 weeks, they are aged 16 years and older and they have booked for their maternity care to be provided by Liverpool Women’s NHS Foundation Trust.

Innovative data collection methods will be used to assess areas including child development, neighbourhood and family context, family structure, physical and mental health and the home environment. Furthermore, record linkage will be in place for areas such as health and educational information. Human samples will be collected antenatally and around the time of delivery and stored for future use.


The C-GULL Study is a clinical research platform that is open to research access requests across academic, clinical and commercial partners.
