Severity of nausea and vomiting in pregnancy and early childhood neurobehavioural outcomes: The Growing Up in Singapore Towards Healthy Outcomes study.

Background: Nausea and vomiting of pregnancy (NVP) affects 50 to 80 per cent of women. The existing literature has examined NVP from the perspective of the mother, and relatively less is known about offspring outcomes.

Objectives: To study the relationships of NVP with social-emotional, behavioural, and cognitive outcomes of the offspring in a multi-ethnic Asian cohort.
