Formatted Abstract/Summary
Background: Research to determine strategies to delay or prevent the development of Type 2 Diabetes Mellitus (T2DM) is vital, particularly in proven high risk population groups, including women previously diagnosed with Gestational Diabetes Mellitus (GDM), plus BMI >25kg/m2.

Methods: In a three month trial, 24 women with a history of GDM 6 to24 months prior to enrolment and BMI > 25 kg/m2 provided informed consent and were randomly assigned to receive either usual care (UC, n=12) or an intervention (INT, n=12) consisting of (1) an internet-supported pedometer program designed to increase physical activity through walking, and (2) a healthy eating four session workshop underpinned by behaviour change theory. The primary outcome was change(∆) in weight from 0 to 3 months. Secondary outcomes included glucose metabolism (assessed using fasting glucose, fasting insulin and HOMA IR as an estimate of insulin resistance) and body composition (assessed using bio impedance methodology).

Results: Twelve UC and seven INT women returned for three month follow up and form the basis of this report. At three months, Mean(SD) results were as follows: ∆Weight: INT group -2.5(2.3) kg vs. UC group +0.2(1.6) kg (p=0.009). ∆Waist circumference: INT group -3.6(4.5) cm vs. UC group -0.1(3.6)cm (p=0.07). ∆ Hip circumference: INT group -5.0(3.3) cm vs. UC group -0.2(2.6) cm (p=0.002). There were no significant changes in glucose metabolism at 0 to 3 months or between groups. Body composition were as follows: ∆ Body fat: INT group -1.3(3.3)% vs. UC group 0.4(1.7)% (p=0.19). ∆ Lean body mass: INT group 0.3(2.8)% vs. -0.7(3.6)% (p=0.58).

Discussion: This combined physical activity and dietary intervention proved effective in promoting short term weight loss in women with previous GDM and deserves consideration in larger scale studies. No changes in glucose metabolism or body composition were demonstrated. Despite multiple recruitment strategies including media involvement, recruitment proved difficult.
