“…We compared the prevalence rates obtained in this study with those in three earlier studies conducted in Chennaithe first in 1989 [4], the second in 1995 [5] and the third, the National Urban Diabetes Survey (NUDS) in 2000 in six cities, including Chennai [6]. All three studies used WHO criteria for the diagnosis of diabetes and IGT and were conducted on a representative population of Chennai which takes socio-economic diversity into account.…”

“…For the present analysis the following five studies were included; the INTER99 study [14], the Paris Prospective Study [15], the Qingdao study from China [16], the National Urban Diabetes Study (NUDS) from India [17] and the Third National Health and Nutrition Survey (NHANES III) from the US [18]. Basic characteristics of each of the five study populations are given in Table 1.…”

“…To estimate the impact of the proposed change in diagnostic criteria on the total number of individuals with IFG in the three largest countries (India, China and USA), the age-specific prevalence of IFG for the age intervals 40 to 54 and 55 to 64 years was calculated on the basis of the above studies [16,17,18]. Population data on the number of individuals in each of these age categories were taken from the website of the United Nations Statistical Office (http://www.un.org/esa/population/ unpop.htm) [19].…”

Aims/hypothesis. In November 2003 the American Diabetes Association expert committee on the diagnosis and classification of diabetes mellitus suggested a revision of the diagnostic criteria for IFG, lowering the diagnostic threshold from 6.1 to 5.6 mmol/l. The aim of the present study was to evaluate the consequences of this change with respect to: (i) the prevalence of IFG in five different countries; (ii) the concordance between IFG and IGT (classification of individuals); and (iii) the cardiovascular risk profile of these groups. Finally we discuss the likelihood that intervention for cardiovascular risk and prevention strategies developed for individuals with IGT are applicable to subjects with IFG. Methods. The first part of the study is based on the population-based Danish Inter99 study, where 6265 individuals, aged 30 to 60 years and without previously diagnosed diabetes, underwent an oral glucose tolerance test. The second part is based on the DETECT-2 project, in which studies from China, India, France and USA were used to analyse the impact of the proposed revision of the diagnostic criteria in different ethnic groups. Results. The proposed change in diagnostic criteria would increase the prevalence of IFG in Denmark from 11.8 to 37.6%. The proposed IFG category would identify 60.0% of all subjects with IGT compared to 29.2% with the old criteria, but among individuals with the new IFG category only 18.5% would also have IGT. Individuals with isolated IFG had lower insulin levels and a lower cardiovascular risk profile with the proposed criteria compared with the current WHO criteria. Data from the DETECT-2 study confirmed the marked increase in the prevalence of IFG, and the estimated number of individuals in the age range 40 to 64 years with IFG in urban India, urban China and the USA would increase by 78%, 135% and 193% respectively. Conclusions/interpretation. The proposed revised diagnostic criteria will lead to a dramatic increase in the prevalence of IFG, but the concordance rate between IFG and IGT remains low. This new IFG group will have a more favourable cardiovascular risk profile than the current IFG group as defined by the WHO. This seriously questions whether the existing intervention strategies are applicable to the new category of individuals with IFG.

“…In a study conducted in the urban (n = 1806) populations of Moradabad, the prevalence of diabetes was 6.0% (15). Ramachandran et al assessed the prevalence of DM in 11,216 subjects in six major cities and found the prevalence of diabetes to be 13.5% among Chennai residents, in Bangalore-12.4%, Hyderabad-16.6%, Kolkata -1.7%, New Delhi -11.6%, and in Mumbai -9.3% (16).…”

The central role of the laboratory scientist is to aid the clinician, in interpreting observed values, by providing relevant reference values in a convenient and practical form. In India, reference values used in laboratories have been established in the western population. But these can be questioned due to differences in genetic load, lifestyle, and diet. This review highlights the approach for establishing reference values in our population using the IFCC guidelines and our observations from our data as compared to the reported values in our laboratory.
