Low cognitive function is linked to impaired fasting glucose in late adolescence, according to new research.
The study, conducted by researchers at Chaim Sheba Medical Centre in Israel, found that the general intelligence score (GIS) of each participant affected their risk of impaired fasting glucose.
Based on their GIS, 17,348 adults without diabetes or impaired fasting glucose were divided into three groups: low score, medium score and high score. 87 per cent of participants were men, with a mean age of 31 years. The GIS scores were taken from the participants at the age of 17. The researchers measured the fasting plasma glucose levels of the participants every three to five years.
The researchers found that the participants in the lowest GIS group of had a significantly higher risk of impaired fasting glucose than participants in the highest group.
“On a clinical level, along with family history of diabetes, fasting plasma glucose, [triglyceride] level, [white blood cell] counts and BMI, assessment of cognitive function may serve as a marker of overall health and aid in the identification of those at increased risk of dysglycemia,” the researchers wrote.
“On a research level, these findings may be the basis for further research exploring the mechanistic routes that underlie the cognitive-dysglycemia relationship.”
The findings were published in the Journal of Clinical Endocrinolgy and Metabolism.
