Primary outcome [1] 0 0
Neurocognitive disability - The primary outcome is a competing composite endpoint of neurocognitive disability and death. Neurocognitive disability is a composite outcome related to social impairments, executive function, emotional and behavioural problems which have been associated with Autism Spectrum Disorder (ASD). It will be defined by an abnormal score on any of three standardized and validated assessment tools: SRS-2 BRIEF-P, or CBCL which will be administered to the parents of children aged 4-6 years. Deaths reported between 6 weeks to 4-6 years of age will be recorded as a competing event and treated as part of the primary endpoint.
Timepoint [1] 0 0
From six weeks of age to date of data collection taken at one time point between the ages of 4 to 6 years.
Secondary outcome [1] 0 0
Severe Morbidity - Secondary outcomes to be assessed in FACT 4 Child include severe morbidity of FACT offspring, captured by the Mother-Child Health Survey at the age of 4 - 6 years, including incidence of: Severe morbidity defined by any illnesses during the previous years that has necessitated hospitalization or medication/treatment for >2 months
Timepoint [1] 0 0
From six weeks of age to date of data collection taken at one time point between the ages of 4 to 6 years.

Brief summary
FACT 4 Child is a follow up study of mothers who participated in the Folic Acid Clinical
Trial (NCT01355159) and their children at 4-6 years of age to determine the effect of high
dose folic acid supplementation on social impairments associated with Autism Spectrum
Disorders (ASDs), and deficiencies in a range of executive function and emotional and
behavioural problems in young children, and the risk of death.
