The MoMMii Study. Diabetes Prevention Intervention on Families With Past Gestational Diabetes (MoMMii)

The MoMMii Study: Effects of a Multimodal Diabetes Prevention Intervention on Families With a History of Gestational Diabetes

Women with gestational diabetes (GDM) have increased risk of developing type 2 diabetes; their children show more insulin resistance and diabetes compared to offspring of mother without diabetes in pregnancy. An increased diabetes risk is also observed among partner of adult with prediabetes/type 2 diabetes. The investigators have pilot-tested a program for diabetes risk reduction among women within 5 years of a GDM pregnancy (MoMM program). The investigators are now enhancing the program to engage directly the partner (MoMMii program).

In MoMMii, 66 couples with a history GDM in the mother will participate in a multimodal diabetes prevention program that includes healthy meal preparation training, discussion of eating and physical activity behaviours and developing home environments that facilitate healthy habits, pedometer-based step count monitoring, and participation in family-based activities (frisbee, soccer) as well as individual exercise (e.g., use of exercise equipment, floor resistance exercises). Participants will be encouraged to communicate between sessions with study personnel and with one another to create a between family support network. All mothers and fathers will participate in five sessions over six months. The investigators will examine changes in health-related behaviours, blood pressure, glucose levels, and insulin sensitivity/resistance in both mothers and fathers.

Study Overview

• Status: Completed
• Conditions: Gestational Diabetes Mellitus With Baby Delivered
• Intervention / Treatment: Behavioral: Nutrition/physical activity intervention

Detailed Description

The primary goal of the project is to determine if, among families with a history of gestational diabetes mellitus (GDM) in the mother in the prior five years, a family-based multimodal health behaviour intervention (group cooking and eating/physical activity counselling, telephone-based app and text support, building of peer and within-family social support for health behaviour change) will lead to reductions in post 75g glucose load serum glucose values in mothers and fathers. The previous MoMM pilot study demonstrated an 8% reduction in mothers, similar in magnitude to that observed in a large diabetes prevention trial conducted among adults with impaired glucose tolerance (Tuomieltho et al, N Engl J Med 2001). MoMMii will ascertain if expansion to a family-based approach amplifies effects in mothers and demonstrates impact in fathers and children. Thus, MoMMii will shift the focus from the mother to the family. A systematic review and meta-analysis showed diabetes risk to be shared between spouses (Leong et al, BMC Medicine, 2014). GDM also confers higher risk for insulin resistance and overweight in offspring. Thus, this project plans to create a collaborative home environment that facilitates choices consistent with diabetes prevention for all family members. Sixty-six families will be recruited through GDM clinics at McGill University Health Centre and other centres. Five in-person sessions (meal preparation training, eating and physical activity counselling) will take place once a month at the PERFORM Centre, Concordia University. Each session will involve discussion of strategies to achieve healthy eating, hands-on meal preparation, and group-based physical activity. Sessions will engage couples as well as mothers and fathers separately. 'Healthy living' concepts will be integrated into the on-site childcare structure (meal preparation, games, videos). The intervention team will include a dietitian and kinesiologist. A health coach will facilitate networking among participating families and development of lay group leaders to sustain health behaviour changes between sessions and post program. Outcomes will be evaluated in mothers, fathers (e.g., fasting and post load glucose and insulin resistance measures, fruit/vegetable intake, step counts, eating behaviours, blood pressure) and offspring (dietary/physical activity habits).

Intervention / Treatment

Experimental: Nutrition/physical activity intervention; There will be five in-person group sessions (3 to 4 weeks appart) with on-site child care. Sessions will include preparation of a healthy meal (hands-on) and discussions of mindful eating, balanced meals, portion sizes, and preparing food at home, under a dietitian's supervision. Sessions will also include a one-hour physical activity information/practice session with a kinesiologist. Participants will track daily step counts with a pedometer and aim to eventually reach more than 10,000 steps/day. They will also receive instruction and demonstration from a kinesiologist of some simple resistance exercises they may perform at home. Between sessions, participants will receive advice and support through a study-specific website, telephone calls and phone applications.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in post 75 gram glucose load 2-hour glucose value in mothers and fathers	Following an overnight fast and venous blood sampling for fasting glucose, a 75 gram glucose solution will be consumed by the participant and two hours later, venous blood will be sampled for a repeat serum glucose assay. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in fruit and vegetable consumption in mothers and fathers	Estimates of consumption based on food frequency questionnaire data completed by mothers and fathers. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in physical activity in mothers and fathers	Daily physical activity assessed by accelerometers and pedometer-based step counts in mothers and fathers. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in insulin resistance measure (HOMA-IR) in mothers and fathers	Homeostatic Assessment of insulin resistance (HOMA-IR) calculated with fasting glucose and fasting insulin values. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in insulin sensitivity measure (ISI 0,120) in mothers and fathers	Using the ratio of the serum insulin levels at the 0 minute and 120-minute time points, the insulin sensitivity index (ISI 0, 120), another marker of insulin resistance, will be calculated as proposed in Gutt M, Davis CL, Spitzer SB, Llabre MM, Kumar M, Czarnecki EM et al. Validation of the insulin sensitivity index (ISI(0,120)): comparison with other measures. Diabetes Res Clin Pract 2000; 47(3):177-184. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in fasting glucose in mothers and fathers	Following an overnight fast, venous blood will be sampled for assessment of fasting glucose. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in fasting insulin in mothers and fathers	Following an overnight fast, venous blood will be sampled for assessment of fasting insulin. The pre-intervention value will be subtracted from the post-intervention value to compute the change during the intervention.	20-24 weeks
Change in systolic blood pressure in mothers and fathers	Systolic blood pressure will assessed with the participant seated in a quiet room with the arm supported. Measurements will be taken with an automated device at 1-minute intervals for 6 sequential measurements. The latter 5 measurements will be averaged. The pre-intervention (average) systolic blood pressure will be subtracted from the post-intervention (average) systolic blood pressure for computation of the change in systolic blood pressure.	20-24 weeks
Change in diastolic blood pressure in mothers and fathers	Diastolic blood pressure will assessed with the participant seated in a quiet room with the arm supported. Measurements will be taken with an automated device at 1-minute intervals for 6 sequential measurements. The latter 5 measurements will be averaged. The pre-intervention (average) diastolic blood pressure will be subtracted from the post-intervention (average) diastolic blood pressure for computation of the change in systolic blood pressure.	20-24 weeks
