Background and aims: A significant increase in platelet count may be a risk factor for atherosclerotic cardiovascular disease. This study investigates the association between platelet number and glucose metabolism, evaluated by glycated hemoglobin (HbA1c) levels, in a apparently healthy population represented by overweight and obese subjects with normal glucose and HbA1c levels. Methods and results: As many as 240 subjects, 177 women and 63 men, aged 18–70 years, were enrolled. Body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure levels, platelet count and fasting blood glucose, insulin, insulin resistance, HbA1c, uric acid, triglyceride, total cholesterol, high and low density lipoprotein cholesterol concentrations were evaluated. Concerning the univariate correlation analyses between platelets number and all other variables, platelet count was significantly (and positively) correlated only with HbA1c (P < 0.05) and female sex (P < 0.01). HbA1c (P < 0.05), female sex (P < 0.001), and diastolic blood pressure (P < 0.01), positively, and age (P < 0.05) and systolic blood pressure (P < 0.05), negatively, were significantly and independently associated to platelet count in a final multiple regression analysis. Conclusion: This is the first study showing a strong positive and independent relationship between HbA1c and platelet number in non-diabetic overweight and obese subjects.

Abstract

Background and aims: A significant increase in platelet count may be a risk factor for atherosclerotic cardiovascular disease. This study investigates the association between platelet number and glucose metabolism, evaluated by glycated hemoglobin (HbA1c) levels, in a apparently healthy population represented by overweight and obese subjects with normal glucose and HbA1c levels. Methods and results: As many as 240 subjects, 177 women and 63 men, aged 18–70 years, were enrolled. Body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure levels, platelet count and fasting blood glucose, insulin, insulin resistance, HbA1c, uric acid, triglyceride, total cholesterol, high and low density lipoprotein cholesterol concentrations were evaluated. Concerning the univariate correlation analyses between platelets number and all other variables, platelet count was significantly (and positively) correlated only with HbA1c (P < 0.05) and female sex (P < 0.01). HbA1c (P < 0.05), female sex (P < 0.001), and diastolic blood pressure (P < 0.01), positively, and age (P < 0.05) and systolic blood pressure (P < 0.05), negatively, were significantly and independently associated to platelet count in a final multiple regression analysis. Conclusion: This is the first study showing a strong positive and independent relationship between HbA1c and platelet number in non-diabetic overweight and obese subjects.
