MiTy Kids (Metformin in Women With Type 2 Diabetes in Pregnancy Kids Trial)

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.

Further study details as provided by Mount Sinai Hospital, Canada:

Primary Outcome Measures:
  • Adiposity in the offspring [ Time Frame: 24 months ]
    Anthropometric measures: BMI and sum of skinfolds (triceps, subscapular, suprailiac and biceps).

Secondary Outcome Measures:
  • Sum of skinfolds in the offspring [ Time Frame: 6, 12 and 24 months ]
    Triceps, subscapular, suprailiac and biceps.

  • Central to peripheral adiposity in the offspring [ Time Frame: 6, 12 and 24 months ]
    Suprailiac to triceps skinfold ratio.

  • Weight gain, BMI and weight-for-length percentile change over time in critical early periods and overall in the offspring. [ Time Frame: 3, 6, 12, 18 and 24 months ]
    Weight and length.

  • Overweight and obesity in the offspring [ Time Frame: 3, 6, 12, 18 and 24 months ]
    BMI >85th percentile (overweight) and BMI >97th percentile (obesity) for age and gender from World Health Organization (WHO) growth charts.

  • Insulin resistance in the offspring [ Time Frame: 24 months ]
    Fasting insulin, fasting insulin-to-glucose ratio, and the Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR).

  • adipocytokine profile in the offspring [ Time Frame: 24 months ]
    Adiponectin and leptin.
