Conclusions HbA1c is neither sensitive nor specific for detecting pre‐diabetes ; fasting glucose is specific but not sensitive .
Interventions in people classified through screening as having pre‐diabetes have some efficacy in preventing or delaying onset of type 2 diabetes in trial population s. As screening is inaccurate , many people will receives an incorrect diagnosis and be referred on for interventions while others will be falsely reassured and not offered the intervention .
These findings suggest that “ screen and treat ” policies alone are unlikely to have substantial impact on the worsening epidemic of type 2 diabetes .

lmplementing lifestyle change through phone-based motivational interviewing in rural-based women with previous gestational diabetes mellitus.
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 result ed 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 r and omly 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
