The prevalence of Type 2 diabetes and its associated health problems in a community-dwelling elderly population

Aims Prevalence estimates of Type 2 diabetes and its associated health problems in elderly populations are rare, especially in the very elderly. Methods A sample of 15 095 community‐dwelling older people aged ≥ 75 years were assessed. Type 2 diabetes and associated health problems were identified using self‐reporting, general practitioner records, drug histories, and blood and urine measurements. Results There were 1177 people identified as having Type 2 diabetes mellitus, giving an overall prevalence of 7.8% (95% confidence interval 7.1, 8.5), 9.4% (8.4, 10.5) for men and 6.8% (6.1, 7.6) for women. The age, sex and smoking adjusted odds ratios for various health problems, comparing people with and without diabetes were: low vision 1.6 (1.3, 1.9), proteinuria 1.7 (1.4, 2.1), chronic kidney disease stage 4 or 5 1.5 (1.0, 2.1), angina 1.3 (1.1, 1.6), myocardial infarction 1.5 (1.2, 1.8), cerebrovascular event 2.0 (1.8, 2.1) and foot ulceration 1.7 (1.2, 2.4). Conclusions The prevalence of Type 2 diabetes is not high in community‐dwelling older people, but diabetes was a contributory factor to a number of health problems.
