Issue addressed Substantial numbers of women with past gestational diabetes mellitus (GDM) develop type 2 diabetes mellitus (T2DM). In northern New South Wales 23% of women attending diabetes services between 2007 and 2010 with T2DM previously had GDM. This study investigated whether phone‐based lifestyle education using motivational interviewing resulted in positive lifestyle change post GDM for women in a large rural area. Method Thirty‐eight women were recruited to this pilot study following GDM diagnosis and randomly allocated to either the control or intervention group. Following baseline assessment, the intervention group received a 6‐month phone‐based motivational interviewing program, and access to usual care. The control group received usual care only. Measures were collected at baseline (6 weeks postnatal), and at 6 months follow‐up. Outcome measures included body mass index, diet, and physical activity. Results At follow‐up, the intervention group compared to the control group significantly reduced total fat intake by −19 g/d (95%CI: −37 to −1), total carbohydrate intake by −42 g/d (95%CI: −82 to −1), and glycaemic load by −26 units (95%CI: −48 to −4). These women also increased leisure physical activity compared to the control group by 11 min/d (95%CI: 1 to 22); no significant change in total physical activity levels occurred. At follow‐up, body mass index in the intervention group improved by −1.5 kg/m2 (95%CI: −2.8 to −0.1) compared to the control group. Conclusion The intervention group showed positive trends across lifestyle variables compared to the control group. Further large‐scale research on the effectiveness of phone‐based lifestyle counselling following GDM is warranted. So what? Phone‐based motivational interviewing may be effective in improving the lifestyle of rural women with previous GDM, and warrants evaluation in larger controlled trials.
