Objective: To recognize the prevalence of impaired fasting glucose level (IFG) and impaired glucose tolerance (IGT) in general population of Depok Area, West Java.
Methods: the study was conducted in a population with age > or = 25 years, in Depok Area, West Java, which was selected by using two stage random sampling. Data were collected by using the Step Wise Approach of WHO. Subjects without previous diabetes history were categorized as diabetes if their fasting blood glucose level > or = 126 mg/dL, and or the 2-hour-after 75 gram glucose load > or = 200 mg/dL. While pre-diabetes was defined as IFG when the fasting blood glucose > or = 100 mg/dL to < 126 mg/dL or IGT when the 2-hour-after 75 gram glucose load level > or = 200 mg/dL (ADA 2003).
Results: of 1200 participants, there were 975 participants who fulfilled the invitation and there were 969 eligible participants to be evaluated. Among the participants aged > or = 25 years, there were 40 (4.13%) subjects with isolated IFG and 234 (24.25%) subjects with isolated IGT, 55 subjects (5.68%) with mixed IFG/IGT.
Conclusion: the prevalence of isolated impaired fasting blood glucose in population with age > or = 25 years is 4.13%; while the prevalence of isolated impaired glucose tolerance is 24.25%. Mixed IFG/IGT is 5.68%. The total prevalence of pre-diabetic patients is 33.96%.
