Brief Summary:
The overall aim of this project is to understand the independent roles of maternal factors, intrauterine exposures, genetic factors, and postnatal environment on the development of obesity and youth-onset type 2 diabetes (T2D) in childhood.

Condition or disease Intervention/treatment
Type 2 Diabetes Gestational Diabetes Mellitus Other: Observational screening study

Detailed Description:

Our primary objective for the study is to clinically and metabolically phenotype parents and their offspring to identify risk factors for obesity, T2D, and cardiometabolic risk in childhood and adolescence in a prospective birth cohort by reporting:

  1. Maternal and/or paternal factors including anthropometrics, metabolic parameters, HNF1a genotype, lifestyle (diet and physical activity), and socioeconomic environment.
  2. Infant factors including anthropometrics, early infant nutrition, and metabolism.

Secondary Objectives:

  1. To evaluate if children born to mothers with T2D prior o pregnancy are at increased risk of obesity and T2D.
  2. To determine the modifiable risk factors which contribute to the increased risk of obesity and T2D.
  3. To evaluate the differential risk between mothers and fathers with T2D in terms of somatic and genetic contributions to risk compared to intrauterine environmental contributions to risk.
  4. To plan a large-scale, randomized, controlled community-based breastfeeding intervention with intensive breastfeeding counseling and support for the prevention of T2D development in offspring of mothers or fathers with youth onset T2D.
  5. To explore potential new research questions and feasibility studies for epigenetic studies using cord blood under the umbrella of the new research theme on T2D at the Children's Hospital Research Institute of Manitoba.

Group/Cohort Intervention/treatment
Next Generation Cohort
We will follow the children from mothers who either have T2D, GDM, or are controls.
Other: Observational screening study

Primary Outcome Measures :
  1. Obesity [ Time Frame: 18 years ]
    Development of obesity defined by the International task force on obesity cut offs for age and gender.

  2. Type 2 Diabetes [ Time Frame: 18 years ]
    Development of type 2 diabetes defined by diagnostic criteria in the Canadian Diabetes association 2008 guidelines in childhood (≤ 7 years) or adolescence (12-16 years).

Biospecimen Retention:   Samples With DNA

For pregnant women: hemoglobin A1C, fasting lipid panel, adiponectin, leptin, apolipoprotein A and B, AST, and ALT, and HNF1a carrier status.

At birth: In offspring: HNF1a status, apolipoprotein A and B, glucose, insulin, c-peptide, and free fatty acid, leptin, and adiponectin, c-reactive protein (CRP), cytokines (interleukins and TNF alpha) will be tested on cord blood.

age 1 to18 - creatine, albumin measurements, and urinalysis. Also, starting at age 6 and every 2 years afterward, urine will be frozen to test for biomarkers that may predict kidney damage or uncover causes for kidney damage in the future.

age 7 to 18 - hemoglobin A1C, blood glucose levels, insulin levels, apolipoprotein A and B, c-reactive protein, lipoprotein profile, ALT, AST, leptin, and adiponectin.

Ages Eligible for Study:   up to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Sampling Method:   Non-Probability Sample
Study Population

Children between the age of 0 and 18 or until a diagnosis of type 2 diabetes.

Diagnosis of diabetes will be made according to the Canadian Diabetes Association criteria. There must be 2 abnormal blood glucose tests on different days OR 1 abnormal blood glucose test + symptoms of diabetes:

Fasting plasma glucose of > 7.0 mmol/L or Random glucose > 11.1mmol/L or 2-hour glucose > 11.1 mmol/L after a standard oral glucose tolerance test (75g).


Inclusion Criteria:

  • Pregnant women with type 2 diabetes, gestational diabetes, or no diabetes.
  • From self-identified Indigenous heritage (e.g., Cree, Oji-Cree, Métis, Anishinaabe, etc.).
  • Are delivering and residing in Manitoba.
  • Mother/Father and children must be biological family members.

Exclusion Criteria:

  • Mothers or children with type 1 diabetes.
  • Residing outside of Manitoba.
