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 .

Outcome of intensive integrated intervention in participants with impaired glucose regulation in China
Introduction This study investigated the outcomes and identified influencing factors of intensive integrated intervention over 2 years in Chinese patients with impaired glucose regulation ( IGR ) . Methods Adults in Beijing , China , were screened for IGR using the 75 g oral glucose tolerance test . Participants with IGR received lifestyle and health education ; those who still had IGR after 1 year were r and omly assigned to either a routine care group or to an intensive integrated intervention group . Results Of 2344 adults screened , 463 had IGR . Of these , 210 adults had IGR after 1 year and were therefore recruited and r and omized to an intensive integrated intervention group ( n=106 ) or a control group ( n=104 ) . The percentage of patients who reached the set targets of plasma glucose , blood pressure , body mass index , or triglycerides was significantly higher in the intensive integrated intervention group . None of the patients within the intensive integrated intervention group progressed to diabetes , whereas eight ( 9.3 % ) cases of the control group developed type 2 diabetes mellitus ( T2DM ) . Logistic regression analysis showed that both an increase in waist circumference and systolic blood pressure ( SBP ) were positively correlated with the development of T2DM , whereas improvement in islet beta cell function was negatively correlated with the development of T2DM . Conclusions Intensive integrated intervention may significantly decrease the conversion rate of IGR to T2DM , and increase the conversion ratio to normal glucose tolerance . The increase of waist circumference or SBP and the deterioration of islet beta cell function may be important risk factors for progression from prediabetes to diabetes
