CONCEPTT Kids International Neurodevelopmental Outcomes Among Offspring of Women With Type 1 Diabetes

Study Overview
=================
Brief Summary
-----------------
Neurodevelopmental Outcomes among Offspring of women with Type 1 Diabetes: A Follow up Study of the CONCEPTT Randomized Control Trial (CONCEPTT Kids International). An international, multicentre prospective cohort study of child and mother pairs. The potential number of recruits is 225 and the main inclusion criteria is child's mother who participated in the CONCEPTT Trial.

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Childhood executive function | The BRIEF2 (Behaviour Rating Inventory of Executive Function - Second Edition) is a parent-report 63 item questionnaire will be utilized to measure of executive function in school-aged children and adolescents (5-18 years of age). The BRIEF2 (Behaviour Rating Inventory of Executive Function - Second Edition) provides three broad index scores (i.e., Behaviour Regulation, Emotional Regulation, and Cognitive Regulation) and a General Executive Composite score. Results are provided in the form of T scores (mean=50, SD=10) with higher scores indicative of greater executive function difficulties; T scores of 65 are considered clinically elevated and indicative of executive function deficits. | 15 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Significant associations between maternal pre-existing diabetes and ASD (Autism Spectrum Disorder) | 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 (Autism Spectrum Disorder). The investigators will use a parent-completed questionnaire; the Social Responsiveness Scale-2 (SRS-2) for behaviours associated with ASD (Autism Spectrum Disorder). | 15 minutes | 
| Significant associations between maternal pre-existing diabetes and ADHD (Attention Deficit Hyperactivity Disorder) | The secondary outcome measures were chosen based on our systematic review and meta-analysis, which identified significant associations between maternal pre-existing diabetes and ADHD (Attention Deficit Hyperactivity Disorder). The investigators will use a parent-completed questionnaire; the ADHD Rating Scale-5 (ADHD-5) for ADHD (Attention Deficit Hyperactivity Disorder) symptoms. | 15 minutes |
