OBJECTIVES: This study was conducted to evaluate the risk factors associated with cardiovascular disease. METHODS: By the questionnaire, the informations of education level, monthly income, alcohol consumption and smoking habit were obtained. Height, weight and blood pressure(BP) were measured by a trained nurse. The level of fasting blood sugar(FBS), total cholesterol, hight-density lipoprotein(HDL) cholesterol and triglyceride were tested by enzyme method about a group of 2888 males and 1696 females ages over 20 who had never taken the medication for hypertension. Statistical analysis, ANOVA, stepwise multiple regression, correlation analysis were performed using SAS package program. RESULTS: There were significant differences among age groups in systolic and diastolic blood pressure, body mass index(BMI), FBS, triglyceride and cholesterol except HDL-cholesterol. The risk factors associated with systolic and diastolic BP significantly in male were BMI, age, alcohol intake, but in female BMI, age. Smoking habit had a significant negative correlation with BP in both sex. In the group of mild hypertension (> or =140 mmHg or> or =90 mmHg defined by JNC-VI) and hypertension (> or =160 mmHg or > or = 95 mmHg defined by WHO), the percent of diabetes (FBS> or =140 mg/dl), hypercholesterolemia (> or =240 mg/dl), and hypertriglyceridemia (> or =200 mg/dl) were signifcantly higher compared with normal group in male and female. BMI, and alcohol consumption had a positive correlation with FBS, total cholesterol and triglyceride. Smoking had a positive correlation with cholesterol and triglyceride but negative correlation with HDL-cholesterol in male. The educational attainment had a negative correlation with BMI, FBS, total cholesterol and triglyceride in female. CONCLUSIONS: This study suggested that drinking, smoking, and BMI and lower educational level were associated with hypertension, hyperlipidemia and diabetes, but further evaluation was needed by prospective intervention study.
