Efficacy of Risk Factors Management on Decreasing Systolic Blood Pressure Level in Hypertensive Patients at Bang Yai Hospital, Nonthaburi-ประสิทธิผลของการควบคุมปัจจัยเสี่ยง ในการลดระดับความดันโลหิตซิสโตลิค ในผู้ป่วยโรคความดันโลหิตสูง โรงพยาบาลบางใหญ่ จังหวัดนนทบุรี

บทคัดย่อ

             This quasi-experimental study was designed to evaluate a decrease of systolic blood pressure (SBP) in 86 new hypertensive patients at Bang Yai hospital during January 2007 - June 2008. Of which, 32 were advocates of risk factors control program and 54 underwent normal treatment procedure. Descriptive statistics were employed.  Comparisons of average levels of SBP of the two groups were made using independent sample t-test and differences between pre-post average levels of SBP of each group were established by dependent sample t-test. Correlations between the body mass index and the levels of SBP were established by Pearsonีs correlation coefficient.  Associations between the nutritional control and the levels of SBP was tested by independent sample t-test.  It was found that the experimental group showed significant reduction of SBP (p < 0.001) whereas the opposite trend was witnessed in the control group (p < 0.001). Significant associations between DASH diet program or aerobic exercise (³ 30 minute/day) with SBP levels were reported (p < 0.001). The results confirms the effectiveness of the risk factors control program in reducing SBP levels in the patients and the measure should be complementary to the normal treatment procedure.
