OBJECTIVES: The study determined the 8-year incidence of diabetes mellitus (DM) and impaired fasting glucose (IFG), and the current prevalence of DM, IFG, and impaired glucose tolerance (IGT), among respondents of the 1998 Food and Nutrition Research Institute 5th National Nutrition Survey (FNRI-NNS) in the National Capital Region (NCR), Region 3, and Region 4 of the Philippines.

DESIGN: This was a descriptive cohort study.

SETTING: This was a community-based study Including all previous respondents of the 1998 FNRI-NNS survey in NCR, Region 3, and Region 4.

PARTICIPANTS: Out of the previous 1,316 individuals in the 3 areas of the 1998 FNRI-NNS data, a total of 1,085 respondents were included in the Philippine Cardiovascular Outcome Study (PhilCOS) with a response rate of 82 percent. MAIN OUTCOME MEASURE: The study determined the 9-years incidence rate of DM and IFG, and the 2006 If prevalence of DM, IFG, and IGT of the cohort.

RESULTS: The 8-years incidence of DM using fasting Wood glucose (FBG) was 9 percent, and of IFG was 10 percent. The prevalence of DM was 19 percent (combined FBG, 2H PG, and interview). The prevalence of IFG was 9 percent based on the cut-off IFG level of 110-125mg/dL. However, using the newer cut-off level of 100-125mg/dL, the prevalence of IFG increased to 30 percent. The prevalence of IGT was 25 percent.

CONCLUSIONS: The PhilCOS-DM has reported the first 8-year incidence rate of DM and IFG in NCR, Region 3, and Region 4. PhilCOS-DM also determined significant proportions of DM, IFG, and IGT in the cohort that warrant early aggressive intervention for prevention and management.
