The Nursing Interventional Study Of The Application Of Dietary Approaches To Stop Hypertension

DASH dietary patternDASH (Dietary Approaches to Stop Hypertension) dietary pattern was designed for public health presented by Appel in 1997. DASH was designed as a test of eating patterns rather than of individual nutrients in an effort to identify practical, palatable dietary approaches that might have a meaningful impact on reducing morbidity and mortality related to blood pressure in the general population.Appel's test showed that DASH dietary pattern can decrease systolic blood pressure of patients with hypertension by 11.4mmHg, and decrease diastolic blood pressure by 5.5mmHg; and it can also decrease systolic blood pressure of clients with pre-hypertension by 3.5mmHg, decrease diaslotic blood pressure of clients with pre-hypertension by 2.1mmHg. Research also showed that DASH dietary pattern can not only decrease blood pressure quickly and significantly, but also can enhance the therapeutic effects of antihypertensive drugs. United States, Finland, the Netherlands, the United Kingdom have done DASH dietary pattern research. Since 2003, only a few cases results whose period was longer than one year have been reported. At present, the research results of long-term change in diet is difficult to show that blood pressure decline, we need further studies.ObjectiveTo control blood pressures of patients withⅠgrade hypertension, to make the irreversible deterioration of hypertension slow down, to reduce complications of hypertension, to strengthen the efficacy of antihypertensive drugs, to ease the economic burden and psychological burden brought by the cost and side effects of antihypertensive drugs, to improve the daily life quality of patients withⅠgrade hypertension, and to provide instructional reccommendation on daily diet through the intervention of DASH dietary pattern.MethodSelf-made pamphlets were sent, methods as group discussion, individual consultation and communication between patients were used during the health education.Basic information questionnaire were issued to record subjects'height, weight, and daily activity level, methods as home survey and question-and-answer were taken. Their recipes were made according to their own parameters. Without changing their other life patterns, methods as telephone follow-home, follow-up were used to intervene. According to their current medication, the subjects were divided into two groups—with-medication group and without medication group and they were both intervened by improved DASH pattern. Subjects were intervend for twelfe months, and the changes of blood pressures between the two groups were recorded. Blood pressures (SBP and DBP) before the intervention, blood pressures after two months'intervention, after six months'intervention and after twelfe months'intervention were compared, and the changes between two groups were compared too. Two independent samples t test, paired samples t test statistical methods and repeated measure ANOVA were used as data processing, and SPSS 13.0 software was applied for statistical analysis.Result(1) After two months'intervention and six months'intervention, SBP and DBP differences in with medication group and without medication group were significant(P<0.05).(2) There is no cross-effects between groups and intervention time (P> 0.05).(3) After the same intervention period, SBP and DBP differences between the two groups were not significant (P>0.05).(4) After twelfe months'intervention, SBP fell 7.59mmHg in average (P<0.05) and DBP fell 5.11mmHg in average in with medication group(P<0.05). (5) After twelfe months'intervention, SBP fell 7.67mmHg in average (P<0.05) and DBP fell 5.16mmHg in average (P<0.05).(6) After 12 months'intervention, SBP and DBP differences between two groups were not significant (P>0.05).ConclusionBlood pressures can be reduced by improved DASH pattern amongⅠlevel hypertensive patients in northeast of China.Patients withⅠlevel hypertensive can control their blood pressure by means of other than medication, and this is confirmed again by this study.
