Prevalence of diabetes type 2 in older adults: Findings from a large population-based survey in Tehran, Iran (Urban HEART-2).
OBJECTIVE
Diabetes is a common problem in older adults, as they increasingly comprise a larger proportion of patients newly diagnosed with diabetes. The evidence on the prevalence and distribution of type 2 diabetes (DT2) and its related factors among older adults in Iran is sparse. The aim of the present study was to determine the prevalence of DT2 among Iranian older adults aged ≥60years.


METHODS
The study was part of a comprehensive survey (Urban HEART-2) which was a large population-based cross-sectional study. A multistage cluster random sampling method was used to select the participants in Tehran in 2011. All the participants were interviewed by trained personnel using a standard questionnaire on diabetes as well as a socio-demographic checklist. Logistic regression and chi-square were used to investigate the association between diabetes and the demographic characteristics.


RESULTS
A total of 15069 older adults were included in this analysis. The mean age of the participants was 68.93±7.27years (SE: 0.059) and the mean of BMI was 26.21±4.40kg/m2(SE: 0.036). Prevalence of DT2 was 14.4% among Iranian older adults. Factors such as age, being female, high BMI, and education were significantly associated with DT2.


CONCLUSIONS
Given the high prevalence of diabetes among older people, more population based research is needed to quantify the ramifications of diabetes, and to monitor the effects of prevention and health system strengthening strategies on the prevalence, treatment, and control of DT2.
