Objective:To study the distribution of blood glucose among adult residents in Chongqing through analysis of the health data of different gender and age groups.Methods:From January 1st

the proportion of impaired fasting glucose decreased significantly in urban areas(13.35% vs 4.94%

P<0.01);the proportion of impaired fasting glucose in males was significantly higher than in females(8.89% vs 3.72%

P<0.01);the proportions of impaired fasting glucose were significantly different among four age groups(P<0.01)the proportion of.impaired fasting glucose increases with age growing.Conclusion:The residence area
