A survey of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai

Abstract

Objective To investigate the status of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai. Methods In this cross-sectional study, 10 060 permanent residents in Chongming district of Shanghai were surveyed by a random cluster sampling method, with 9 913 subjects aged from 40 to 70 years old. Results Of 9 913 subjects, 3 218 (32.46%) were male with an age of (57.67±7.54) years and 6 695 (67.54%) were female with an age of (55.37±7.82) years. The prevalences of diabetes mellitus (DM), impaired fasting blood glucose (IFG), impaired glucose tolerance (IGT), and IFG+ IGT were 25.57% (2 535/9 913), 9.27% (919/9 913), 15.90% (1 576/9 913), and 9.32% (924/9 913), with the prevalences of pre-diabetes mellitus (PreDM) 34.49% (3 419/9 913) and dysglycemia 60.06% (5 954/9 913). IGT was the main form of PreDM in this survey, accounting for 46.1%. The prevalences of IFG, IFG+ IGT, and DM in male were higher than those of female (all P 0.05). The prevalences of IFG, IFG+ IGT, and DM were decreased with elevated educational levels (all P 0.05). The control rate of blood glucose was decreased with age (P<0.05), and decreased with the increased cultural level(P<0.05). Among the newly-diagnosed diabetic patients, 322 (20.8%) showed the elevation of isolated fasting blood glucose, 609 (39.3%) showed the elevation of isolated postprandial 2 h blood glucose, and 619 (39.9%) showed the elevations of both fasting and postprandial 2 h blood glucose. Conclusion The prevalence of dysglycemia in middle-aged and elderly people in Chongming district of Shanghai is quite high, with low awareness rate of diabetes. The blood glucose control of diabetic patients in Chongqing is far from being satisfied.
