The prevalence of diabetes mellitus (DM) type II among Iranian elderly population and its association with other age-related diseases, 2012.

DM type II is one of the most common chronic diseases. The objective of this study is to investigate the prevalence of DM and its association with other age-related diseases in Iran, 2012. In this cross-sectional study, people aged 60 years and over were selected using multistage sampling method. Mini-Nutritional Assessment (MNA), Activity of Daily Living (ADL), and Geriatric Depression Scale (GDS-15 items) questionnaires were used. History of common disorders was taken through self-report, medical records and the results of clinical examinations. A total of 1350 old people were studied. DM type II was found in 297 (22.0%) subjects and 371 (27.5%) of subjects were not aware of their DM status. Hypertension (55.6%), high serum cholesterol (51.8%), malnutrition (40.1%), Alzheimer's disease (16.9%), weight loss within past year (16.1%), weight gain within past year (11.7%), frailty (64.6%), insomnia (50.1%), and vision problems (62.6%) were significantly more common in diabetics. Those who were not aware of their status of DM either were between diabetics and non-diabetics or more similar to non-diabetics. Considering high prevalence of age-related diseases among Iranian elderly people, in particular women and those with DM type II, preventive measures are recommended so as to decrease and control DM type II and its consequent complications.
