lmplementing lifestyle change through phone-based motivational interviewing in rural-based women with previous gestational diabetes mellitus

Health Promot J Austr. 2012 Apr;23(1):5-9. doi: 10.1071/he12005.


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.
