Women with a history of 'diabetes in pregnancy' or Gestational Diabetes (GDM) have a high risk for type 2 diabetes later in life. This can often be prevented, however, with improvements in eating habits and higher physical activity levels. However, many women find it difficult to alter their lifestyle habits, especially if they have young children. In adults with type 2 diabetes, the investigators have been studying the effects of combining nutrition education with meal preparation training and pedometer-based self-monitoring to improve eating habits and increase activity levels. The investigators have shown that such a strategy can reduce hemoglobin A1C by 0.3% and correlates with small reductions in weight (Dasgupta et al, International Journal of Behavioural Nutrition and Physical Activity, 2012). In developing the present interventional study, we presented this strategy to women with a GDM history and asked them how they would modify it to suit their needs. They expressed strong interest in such an approach but emphasized a need to involve their spouses and provide childcare support. They did not express interest in use of meal replacements. Therefore, in MoMM-intervention phase, the investigators will examine the effects of a once per month (4 session) program combined with Internet/telephone-based support. The four sessions with include meal preparation training, strategies to limit mindless eating and improve meal content and portion control. All sessions will offer child care. Two sessions will involve spouses. The investigators will assess effects on weight, BMI, DXA measures of fat, and measures of insulin resistance and blood pressure. This single-arm intervention study may lead ultimately to a randomized controlled trial.
