title: [Measurement of HbA1c as a method to diagnose diabetes mellitus in nursing home residents].
abstract: Measurement of HbA1c is widely used to control diabetes mellitus (DM) and is one of the methods to diagnose DM. We adopted the measurement of HBA1c in the annual medical examination of residents at a nursing home for the elderly in order to obtain the normal serum level of HbA1c in the elderly and analyze the influence of aging on HbA1c. HbA1c and the body mass index (BMI) were measured in 968 elderly. HbA1c was distributed from 3.7 to 12.5%. Mean and SD, were 5.03 +/- 0.61% and there was no difference of the serum level of HbA1c between males and females. HbA1c was below 6.0% in 95% of all subjects. There was no correlation between age and HbA1c. To determine data trends, we divided the elderly into 4 age groups of 60 to 69 years, 70 to 79 years, 80 to 89 years and 90 or more. With advancing age, HbA1c gradually increased but there was no significant difference of HbA1c among the 3 groups which were younger than the group aged 90 or more. HbA1c was 5.51 +/- 1.06% in the group aged more than 90 years and there was a significant difference in the value of HbA1c between the group aged 90 or more and other groups. Inversely, BMI gradually decreased with age and there was also a significant difference of BMI between the group aged 90 or more and the other groups. These results suggest that there is a difference of metabolic condition between the group aged 90 or more and the other groups.(ABSTRACT TRUNCATED AT 250 WORDS)
