ABSTRACT
BACKGROUND: Through analyzing 1998 National Health Nutrition Survey (NHNS) data, we investigated the prevalence of diabetes mellitus (DM) and several basic factors reflecting the status of DM control: health behaviors, HbA1c level and the prevalence of hypertension among DM patients. METHODS: The NHNS selected 200 districts which represented the national population of Korea and surveyed all inhabitants within the districts. National Health Examination Survey (NHES) and National Health Behaviors Survey (NHBS) surveyed all inhabitants within the related districts. We analyzed the prevalence and management status of DM through analyzing the National Health Interview Survey (NHIS) data of 39,331 responders and NHES data of 10,876 participants. RESULTS: According to NHIS the prevalence of DM was 2.26% for male, 2.03% for female. 11.0% of DM patients exercised more than three times per week. 32.7% were current smokers. 43.1% were drinkers. 30.0% of DM patients had hypertension, but only 15.8% of them controlled blood pressure. From NHES the prevalence of DM was 9.73% for male, 7.95% for female. 10.5% of DM patients exercised more than three times per week. 36.5% were current smokers. 57.4% were drinkers. 45.3% of DM patients had >8% of HbA1c level. 38.1% of DM patients had hypertension, but only 5.3% of them properly controlled blood pressure. CONCLUSION: Considering the results of previous studies, the prevalence of DM have increased rapidly. The level of recognition of patients to control DM, however, was not enough to prevent late complications. Therefore national health policy should be reset to register DM patients and manage them properly.
