Analysis of progression from persons with impaired fasting glucose to diabetes patients in the aged

Objective:To analyse the progression rate from the persons with impaired fasting glucose(IFG)to diabetes patients in elderly.Methods: According to the new IFG diagnosis criterion of American diabetes association in 2003 year,the 140 IFG cases were divided into original IFG cases group(original IFG group 63 cases)and new added IFG cases groups(new IFG group 77 cases),follow-up for four years.Results: The average blood lipid levels,blood pressure,and body mass index(BMI) were no significant difference between original IFG group and new IFG group(P0.05).The rate of progressed to diabetes was 26.98% in original IFG group,it was more than that of new IFG group(18.18%) during four years(P0.05).The annualized progression rate of original IFG group was 8.9%,and was more than that of new IFG group(6.0%).The progression rate to diabetes of original IFG group was 1.5 times to that of new IFG group.The rate for conversion to normal glucose tolerance between original IFG group and new IFG group was no significant difference(P0.05).Conclusion: The incidence of diabetes from cases with original IFG is not only higher than that of new IFG cases,but it is progress rate also more rapidly,so the risk to diabetes of original IFG cases is more than that of new IFG cases.
