Objectives: The objective of the study to determine the prevalence of Impaired Glucose Tolerance and Impaired Fasting Glucose (both combined termed as Pre Diabetes) in the population of Gujarat., Methods: In year 2007 and 2008, a cross sectional survey was conducted via mode of camps at various urban and rural part of Gujarat. After obtaining an informed consent, comprehensive questionnaire was used to collect the various anthropological details, physical examination and blood collection was performed from around 1700 subjects > or = 20 years of age from the different areas of Gujarat. Chi square test was used for all categorical comparisons. Also multiple logistic regression was used for detailed exploratory analysis., Results: The crude prevalence of IFG in Gujarati population is around 2.76% and IGT is around 6.12%. But the age adjusted prevalence of IFG is around 2.72% and IGT is around 4.67%. If we extrapolate these to population of Gujarat, it indicates that around 1.3 million people are having impaired fasting glucose and around 2.3 million people have impaired glucose tolerance. The prevalence of IGT found more after age of 40 years. For IFG, there is increase after age of 40 years, but not significant statistically., Conclusions: High prevalence of IGT validates that there are chances of the pandemic trend in Gujarat, as eventually IGT may get converted into Diabetes in near future. These results need urgent attention to develop a public awareness programme.

Objectives: To develop age and gender specific waist circumference references for urban Indian children aged 3 -16 years., Design: Cross-sectional study., Setting: Urban preschools and schools of Bangalore., Participants: 9060 children (5172 boys and 3888 girls) in the age group of 3-16 years., Methods: Weight, height, and waist circumference were measured using standard anthropometric methodology. Percentiles for waist circumference and Waist/height ratio (W/Ht) for each age and gender were constructed and smoothed using the LMS method., Results: Mean waist circumference increased with age for both girls and boys. The upper end of curve in boys continued to increase, whereas in the girls it tended to plateau at 14 years. The waist circumference of the Indian children from the present study was higher than age and sex matched European children. The proportion of children with W/Ht ratio greater than 0.5 decreased as their age increased., Conclusions: These curves represent the first waist and waist height ratio percentiles for Indian children and could be used as reference values for urban Indian children. We suggest that for a start, the 75th percentile of waist circumference from this study be used as an action point for Indian children to identify obesity (as a tautological argument), while retaining the cut-off of 0.5 for the W/Ht ratio; however this underlines the need to derive biologically rational cut-offs that would relate to different levels of risk for adult cardiovascular disease.
