Abstract
AIMS: Information on the population at risk of developing Type 2 diabetes in the UK is scarce. We used data from the 1958 British birth cohort to estimate geographical and socio-economic variations in HbA(1c) in mid life. METHODS: Participants (n = 7799) born in England, Scotland and Wales and currently living in the UK. Individuals were classified according to the presence of Type 2 diabetes and by thresholds of HbA(1c). HbA(1c)> or = 5.5 was used as an indicator for possible subclinical alterations in glucose metabolism. RESULTS: The majority of the population had HbA(1c) < 5.5% (79.3%); 16.7% had HbA(1c) 5.5-5.9%, 2.0% 6.0-6.9% and 0.6% had HbA(1c)> or = 7.0%. Individuals from manual socio-economic groups and those living in the East of England and Scotland had a higher prevalence of HbA(1c) at or above the upper normal range (5.5%). CONCLUSIONS: Estimates from this nationwide sample suggest that a proportion of Britons are likely to have subclinical alterations in glucose metabolism by their mid 40s, and this proportion is greater in some socio-economic groups and geographical regions than in others.
