AQUA: Asking Questions about Alcohol in Pregnancy Study

This study seeks to produce timely, new information on the complex relationship between low to moderate alcohol drinking patterns in pregnant women and their infant’s health and development. Exposure data was collected through questionnaires administered during each trimester of pregnancy. Data on other factors that could influence the effects of alcohol such as diet, medication and body size was also collected at each follow-up. Mothers then completed a questionnaire about the health and development of their child at one and two years of age.

A subgroup of the cohort was invited for 3D craniofacial photography of their child within four weeks of their first birthday. The same sub-group was also invited to a developmental assessment at two years of age. Biosample collection occurred at two time points: At recruitment all participating women were offered a cheek brush swab for collection of their buccal cells for the measurement of genetic polymorphisms. Around the time of birth, infant buccal swabs, placental tissue and cord blood were also obtained for epigenetic studies.

AQUA at 6: this follow-up of the 6-7 year-old children is underway in 2018-2020, including neurodevelopmental assessment, child buccal swabs (epigenetics), parent-report questionnaire, 3D craniofacial imaging and a brain MRI sub-study.
