Correlates of autonomic nervous system function in a general population with special reference to HbA

As the glucose tolerance of patients with diabetes worsens, autonomic nervous system (ANS) function decreases. Only a few studies, using plasma glucose, have reported on this relationship in large general populations that include people with wide range of glycemia. This study aimed to examine correlates of ANS function with special reference to HbASpectral analysis was performed to assess heart rate variability (HRV) using 1-minute electrocardiogram RR interval data recordings from 7690 residents aged 35-79 years in Nagahama City, Japan. HRV parameters were log-transformed. Multiple regression analysis was performed using potential correlates.lnLF decreased with age (regression coefficient, -0.025; P 0.001), BMI (-0.010; P = 0.035), and HbAAlthough the associations were weak, age, BMI and HbA
