N1 - Funding Information:
The community sample of individuals contacted are from the Age and Cognitive Performance Research Centres (ACPRC) volunteer panel, a group of over 6000 older adults who have been described in detail previously ( Rabbitt et al., 2004 ). This group has participated in a longitudinal study of aging for approximately 20 years, and all volunteers still active in this research in the Greater Manchester area of the UK, were invited to participate in this study in 2001. The study was partially funded by the Unilever Trust. Of the 582 volunteers contacted, 456 agreed to take part in the complete study that involved attending the ACPRC and having a variety of physical measures made and providing samples of saliva, blood and urine as part of a larger study examining multiple factors associated with aging. The participants were also asked to complete a health questionnaire called the CMI ( Rabbitt et al., 2004 ). One question on the paper containing 195 different questions asks, ‘Do you suffer with diabetes (sugar)?’ We used the answer to this question alone to determine whether an individual was known to suffer with DM prior to our study. In total, 436 provided suitable samples and a completed questionnaire. Basic data describing this group are given in Table 1 .

N2 - Reports of diabetes mellitus samples in community-dwelling unselected populations suggest a prevalence of 6%. A further 3% of unknown diabetes mellitus subjects are suggested when using formal biochemical methods of diagnosis. In this study, we present the prevalence of diabetes mellitus by self-reports using the CMI and concomitant biochemical detection in 436 community-dwelling older adults who have participated in a 20-year-study of age and cognitive performance in Manchester, UK. Twenty-three of the group reported that they had diagnosed diabetes mellitus, three individuals had a raised HbA1c of greater than 7.0% on random testing, but no knowledge of having diabetes mellitus. These individuals were re-contacted and three said they subsequently had a diagnosis of diabetes mellitus made within the two years following the questionnaire. We conclude that in an older population of community-dwelling subjects the numbers of undiagnosed cases of diabetes mellitus is lower than anticipated, based on large unselected population samples. The greater opportunity to interact with health care professionals who may consider screening for diabetes mellitus may explain these findings.
