The effect of aging on HbA1c in a working male Japanese population. They found that HbA1c increased with age - the largest increase was in the 40-49 year group with a BMI below 26, and in the 30-39 group with a BMI>26. Hba1c was not related to physical activity, but was related to family history.

The age-dependent increase in HbA1c may be a consequence of the aging process itself.

t is the fastest ageing society in the world and one in five Japanese people is over 65. By 2015, that proportion will have grown to a quarter – 33.8 million people – and it is projected to rise to 40 per cent by 2055.

What was that the
fastest ageing society in the world? Just might go some way to explaining that rising Hba1c.
A significant proportion of the rise is very likely to be due to an ageing population. In the US from my own rough estimate from census figures, approximately half the rise in type 2 is explained by ageing in the US population.
