Study summary

The prevalence of diabetes in pregnancy is rising in all maternal age groups. There is increasing evidence that in-utero exposure to maternal diabetes is associated with an increased risk of obesity and type 2 diabetes in children and adults. There is an urgent need to reduce these increasing rates of obesity and diabetes in subsequent generations.

The MiTy Trial (Metformin in Women with Type 2 Diabetes in Pregnancy Trial) is a CIHR-funded multi-centre, randomized controlled trial of women with type 2 diabetes in pregnancy (sample size n=500). The MiTy Trial is looking to determine the effect of the addition of metformin to a standard regimen of insulin in women with diabetes, on perinatal morbidity and mortality.

The MiTy Kids Trial is a follow-up to the MiTy Trial which will determine whether treatment with metformin during pregnancy in women with type 2 diabetes will lead to a reduction in adiposity and improvement in insulin resistance in the offspring of women with diabetes at 2 years of age.

What researchers measure

Primary outcomes

  1. Adiposity in the offspring

    Anthropometric measures: BMI and sum of skinfolds (triceps, subscapular, suprailiac and biceps).

    Time frame: 24 months

Secondary outcomes

  1. Sum of skinfolds in the offspring

    Triceps, subscapular, suprailiac and biceps.

    Time frame: 6, 12 and 24 months

  2. Central to peripheral adiposity in the offspring

    Suprailiac to triceps skinfold ratio.

    Time frame: 6, 12 and 24 months

  3. Weight gain, BMI and weight-for-length percentile change over time in critical early periods and overall in the offspring.

    Weight and length.

    Time frame: 3, 6, 12, 18 and 24 months

  4. Overweight and obesity in the offspring

    BMI \>85th percentile (overweight) and BMI \>97th percentile (obesity) for age and gender from World Health Organization (WHO) growth charts.

    Time frame: 3, 6, 12, 18 and 24 months

  5. Insulin resistance in the offspring

    Fasting insulin, fasting insulin-to-glucose ratio, and the Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR).

    Time frame: 24 months

  6. adipocytokine profile in the offspring

    Adiponectin and leptin.

    Time frame: 24 months
