HbA1c 5·7–6·4% and impaired fasting plasma glucose for diagnosis of prediabetes and risk of progression to diabetes in Japan (TOPICS 3): a longitudinal cohort study

Retrospective cohort study of the risk of impaired glucose tolerance among shift workers

“…Although a recent study suggested that a combination of FBG and HbA1c more efficiently determines subsets of individuals at risk from developing diabetes (11), it is difficult to obtain FBG measurements from large numbers of workers, particularly shift workers. HbA1c is thought to be less relevant in screening for IGT or diabetes compared to FBG, however, its measurements are not affected by dietary intake before the examination and are regarded as a practical index Oyama et al of average blood glucose levels.…”

Prediabetes and Lifestyle Modification: Time to Prevent a Preventable Disease

“…If current trends continue, 1 in 3 adults will have diabetes by 2050. 6 The total estimated cost of diagnosed diabetes in 2012 is $245 billion. This included $176 billion in direct medical costs and $69 billion in indirect costs.…”

Utility of 75-g Oral Glucose Tolerance Test Results and Hemoglobin A1c Values for Predicting the Incidence of Diabetes Mellitus among Middle-aged Japanese Men -A Large-scale Retrospective Cohort Study Performed at a Single Hospital-

“…Moreover, the coexistence of IFG and IGT is associated with a higher risk of developing diabetes than the presence of IFG or IGT alone (6). Moreover, previous reports have suggested that the combination of a high FPG level and HbA1c value is associated with an increased risk of developing diabetes (7,8). OGTTs are thus considered to be useful for accurately predicting an individual's risk of developing diabetes, and a combination of the abovementioned markers should be employed to diagnose pre-diabetes.…”
