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 .

Preventing type 2 diabetes after gestational diabetes: women's experiences and implications for diabetes prevention interventions.
AIMS To explore factors influencing post-natal health behaviours following the experience of gestational diabetes , and to elicit women 's views about the feasibility of lifestyle intervention to prevent diabetes during the first 2 years after childbirth . METHODS Qualitative study using semi-structured interviews with women who had gestational diabetes . In phase 1 ( 31 women ) , interviews explored the experience of gestational diabetes , ideas about future risk of diabetes and factors influencing post-natal health-related behaviours . Statements were developed summarizing women 's views of lifestyle change to prevent diabetes . In phase 2 ( 14 women ) , interviews explored how the passage of time had contributed to changes in health behaviour , and the statements were used to develop views about diabetes interventions . RESULTS Women were aware of their risk of developing diabetes , but did not always act on such knowledge . Pregnancy motivated behaviour changes to benefit the unborn child , but after delivery these changes were often not maintained . Tiredness , maternal attachment and childcare dem and s were prominent barriers in the early post-natal months . Later , work , family and child development became more significant barriers . Many women became more receptive to healthy eating messages around the time of weaning . Women were positive about long-term support for self-management to reduce their diabetes risk . CONCLUSIONS There is potential to reduce the risk of Type 2 diabetes post-natally among women with gestational diabetes . Interventions need to be developed that take into account context ual factors and competing dem and s , are flexible and respond to women 's individual circumstances . R and omized trials of such interventions are warranted
