This is a multicentre, international prospective cohort study of child and mother pairs from sites in Canada, UK, Spain and Italy. The expected duration of the study is three years. Women who participated in CONCEPTT will be invited to participate in CONCEPTT Kids International. Once informed consent is obtained, mothers will be asked to complete forms and questionnaires that provide information on family socio-demographics and their children's executive functions and behaviour (i.e. social responsiveness and attention). Self-reported height and weight measures of the child and parent(s) will also be collected.~Our primary outcome measure is childhood executive function measured by the Global Executive Composite of the Behaviour Rating Inventory of Executive Function - Second Edition (BRIEF2)~The secondary outcome measures were chosen based on our systematic review and meta-analysis, which identified significant associations between maternal pre-existing diabetes, and ASD and ADHD. We will use two parent-completed questionnaires to assess symptoms associated with these disorders; the Social Responsiveness Scale-2 (SRS-2) for behaviours associated with ASD and the ADHD Rating Scale-5 (ADHD-5) for ADHD symptoms.
