MedicalResearch.com: What is the background for this study? What are the main findings?

Response:  Migraine has further been associated with increased risk of overall and specific cardiovascular disease events.

Because migraine has also been associated with factors related with insulin resistance and type 2 diabetes, an association between migraine and diabetes has been hypothesized.

We observed a lower risk of type 2 diabetes in women with active migraine.

We also show a linear decrease of migraine prevalence long before and a plateau long after type 2 diabetes diagnosis.

MedicalResearch.com: What is the background for this study?
Response: American Diabetes Association (ADA) has set up a lower cut point for diagnosing prediabetes ( those with Impaired Fasting  Glucose   100 mg/dL) compared to the World Health Organization’s cut point, which is 110 mg/dL. This arbitrariness in cut point definition triples the number of cases labeled as prediabetes.

Along with lowering the diagnostic threshold by the ADA, the Centers for Disease Control and Prevention (CDC), the American Medical Association (AMA), and the ADA endorsed and advertised a web-based risk model to define high-risk population for prediabetes. The risk engine asks a few questions ( age, sex, family history of diabetes, history of gestational diabetes and high blood pressure, physical activity and weight) and outputs a score that defines if the person is at risk for prediabetes. We suspected that the risk engine might overestimate the risk.

Pre-Diabetes Associated With Increased All-Cause and Cardiovascular Mortality

Medical Research: What are the main findings of the study?

Response: “Prediabetes” is a general term that refers to an intermediate stage between normoglycaemia and overt type 2 diabetes mellitus (T2DM). It includes 2 groups of individuals, those with impaired glucose tolerance (IGT) and those with impaired fasting glucose (IFG). In 2003, the American Diabetes Association (ADA) redefined the fasting plasma glucose (FPG) concentration range for diagnosing IFG from 110 to 125 mg/dl to 100 to 125 mg/dl in order to better identify individuals at future type 2 diabetes mellitus risk. However, this change has been contentious and was not adopted by the World Health Organization (WHO) Expert Group or other international guidelines.

In this meta-analysis, we included data from 26 prospective cohort studies with for 280,185 participants and found that, after controlling for multiple cardiovascular risk factors, the presence of prediabetes at baseline, defined as defined as IFG of 110 to 125 mg/dL(IFG 110), IGT or combined IFG 110 and/or IGT, was associated with increased risk of all-cause and cardiovascular mortality. Specifically, IFG 110 was associated with 12% and 19% increase of all-cause and cardiovascular mortality, IGT was associated with 33% and 23% increase of all-cause and cardiovascular mortality, combination of IFG110 and/or IGT was associated with 21% and 21% increase of all-cause and cardiovascular mortality, respectively. Although IFG 100 was not associated with all-cause or cardiovascular mortality in the overall analysis, the risk was greater in young and middle age males according to subgroup analyses.

Prediabetes Associated With Increased Cancer Risk

Medical Research: What are the main findings of the study?

Professor Huang: In this meta-analysis of 16 prospective cohort studies comprising more than 890,000 individuals, we found that the presence of prediabetes at baseline associated with a 15% increased risk of cancer overall. The results were consistent across cancer endpoint, age, duration of follow-up and ethnicity. There was no significant difference for the risk of cancer with different definitions of prediabetes (impaired fasting glucose [IFG] and/or impaired glucose tolerance [IGT]).
