Prevalence of undiagnosed and uncontrolled diabetes mellitus among adults in South Chennai

Abstract

Background: Nearly 69.2 million people were living with diabetes as per 2015 WHO data. Prevalence of diabetes in Chennai is always on the rise and it nearly around 12%. The objectives of the study were to estimate the prevalence of undiagnosed diabetes and also to study about the uncontrolled diabetes among known case of diabetes.Methods: A cross sectional descriptive record based study done on 1361 adult population attending medical camps in various locations of South Chennai. The data regarding capillary blood sugar (CBG), age, gender, place, type of treatment and duration of treatment were collected from the camp register. A RBS Glucometer value of >200 mg/dl was defined as having diabetic. Descriptive analysis and chi square test done to see the statistical significance between various parameters. T test was done to compare the mean RBS values between various variables.Results: Among the study population nearly 62.9% were females. The mean age of the study population was 49.8±13.3 years. Nearly 22% were known case of diabetics and 10.3% were newly diagnosed diabetics. The mean random blood sugar of the study population is 174.3±95.3 mg/dl. 65.4% of the known case of diabetics had uncontrolled sugar values of >200 mg/dl. The prevalence of diabetes in age group >50 years (43.9%) and <50 years (20.3%) [p=0.0001]. The mean blood sugar values among patients taking treatment in government (283.5 mg/dl) versus private (249.2 mg/dl) [p=0.0001, among known diabetics (262.5 mg/dl) versus new diabetics (296.6 mg/dl) [p=0.002].Conclusions: The prevalence of newly diagnosed diabetes was 10.3% and uncontrolled diabetes among known case is 65.4%. So more screening camps for early detection of diabetes and organizing health awareness programmes are needed in this population to reduce the disease burden.

Prevalence of risk factors for non-communicable diseases, undiagnosed diabetes and dyslipidemia among doctors as compared with age and gender matched adults in Delhi NCR: a hospital based study

“…In our study, the limited sample size might have resulted in the higher prevalence of undiagnosed diabetes among healthy subjects than that reported in the literature: 10.3% among adults attending medical camps in Chennai and 7.2% among adults visiting health centres across eight Indian states. 17,18 Two-fourth of doctors was observed to have abnormal cholesterol level, similar to that reported among Indian physicians. 19 Moreover, this prevalence was significantly higher than that observed in the healthy subjects.…”

Performance of Indian diabetic risk score as a screening tool of diabetes among women of industrial urban area

“…Those who were known cases of Diabetes mellitus (Type 2) and Non-residents were excluded from the study. Simple random sampling method was adopted using the formulae 4pq/L 2 where P = 10% (Prevalence of undiagnosed diabetes mellitus in South Chennai)[8] and L is the absolute precision(5%)the sample size was calculated to be 150 after taking 10% non-response rate. [8] Medico-social workers attached to our department identified the residential area where the majority of them were insured persons of Employees state insurance act.…”

Prevalence and determinants of poor glycaemic control among adults with type 2 diabetes mellitus in a selected urban population of Mysuru district

“…This finding was slightly more when compared to a study conducted by Rani et al in Mysuru, Karnataka in 2017 which showed a prevalence of 59% and it was almost similar to a study done in South Chennai in 2017 by Ganesh et al which showed 65.4% prevalence for uncontrolled blood sugar levels. 10,13] Another study done by Tripathy et al in Punjab also got similar results with 65% prevalence for uncontrolled diabetes. 14 It was observed that poor glycaemic status was seen more in patients with longer duration of disease which was similar to a study conducted in Jordan by Khattab et al in the year 2010.…”
