Patients and Methods
The study design and research methodology of SN-DREAMS 1 is described in detail elsewhere.7 The study area was the metropolis of Chennai, with a population of 4.3 million, distributed in 155 divisions of 10 zones. The estimated sample size was 5830 (the decision was to enumerate approximately 6000: approximately 600 from each of the 10 zones), assuming the prevalence of DR in the general population to be 1.3% (relative precision, 25%; dropout rate, 20%; design effect, 2).7 The sample was
Results
The data were compared between responders (n = 1563 who visited the base hospital) and nonresponders (n = 253 who did not visit the base hospital) with regard to mean age, gender, diabetes status, and mean fasting blood sugar. No statistically significant differences were observed (Table 1).
The age- and gender-adjusted prevalence of diabetes mellitus for the urban Chennai population was 28.2% (95% confidence interval [CI], 27.0–29.3). The prevalence of diabetes in lower, middle, and high
Discussion
This study (2003–2006) shows that the age- and gender-adjusted prevalence of diabetes mellitus in a population older than 40 years was 28.2%. Table 4 shows various studies on the prevalence of diabetes mellitus from India.12, 13, 14, 15, 16
There were 2 reports wherein the definition of diabetes mellitus was similar to that in the present study; the data showed that the prevalence of diabetes mellitus is rising gradually in India.12, 13 Other reports that used an oral glucose tolerance test in
