Abstract

The purpose of this study was to investigate the relation between hypertension and risk factors. A positive association between obesity, age, serum lipid and such life style factors as smoking, exercise, alcoholic beverage use with blood pressure problems and the prevalence of hypertension has been described in many studies. Therefore to identify and evaluate the effects of variables, which were known to be related to hypertension, multiple regression analysis was performed. We studied 110 subjects. The participants were 45 men and 65 women who visited one university hospital located in Seoul from January to December 1998. All 110 persons were identified as having primary hypertension by their physicians. The significant risk factors identified for hypertension were Obesity, BMI, length of time with hypertension. The results were as follows; 1. The systolic blood pressure average in 110 subjects was 156.65mmHg +/- 14.08mmHg, the diastolic blood pressure average was 100.73mmHg +/- 5.64mmHg. 18.2% of the subjects were smokers, 26.4% of the subjects were drinkers, and 33.6% of the subjects exercised regularly. 13.6% had a family history of hypertension. The average mean pressure was 119.37 +/- 7.40mmHg. The average history of hypertension was 28.36 +/- 34.56months. The average body weight of subjective was 65.25kg, and their average BMI was 24.54kg/m2. The average serum cholesterol of the subjects was 204.54mg/dl, HDL was 50.93mg/dl. 2. The result of this study were that variables which showed significance rationale for high systolic blood pressure in hypertension were mean arterial pressure(R2=0.808), and age(R2=0.032). And the variables which showed significance rationale for diastolic blood pressure in hypertension were mean arterial pressure(R2=0.697), age(R2=0.051), sex(R2=0.014), and somking(R2=0.010). And the best variable for prediction of mean blood pressure was the length of history of the disease. 3. According to multiple regression analysis by demographic variables, age and the length of history of hypertension were predictable variables for hypertension. And mean the blood pressure was identified best explaining variable of hypertension by biophysical variables. Therefore, life style modification for hypertension patients as a primary regimen is less important than for normal blood pressure patients. Life style modification is important intervention for normal blood pressure subjects, on the other hand drug therapy and its compliance is the most important intervention for hypertensive subjects. So to regulate blood pressure and prevent the complication of hypertension, the first regime of all should pharmacologic therapy. There is a need to develop nursing intervention to improve pharmacologic compliance for primary hypertension patients.
