ObjectiveTo explore the influence of community dietary guidance on the effect of blood pressure control by drug and life quality in patients with essential hypertension. MethodsA total of 100 patients with essential hypertension created new files from April 2018 to April 2019 in Shaping Street Community of Heshan city, Guangdong province were selected as the objects. They were divided into observation group and control group by random number table method, 50 cases in each group. Conventional medical therapy was employed to the control group, whereas the observation group was given community dietary guidance intervention on the basis of conventional medical therapy, with 12-month continuous intervention. Blood pressure, SF-36 scale scores, and rehospitalization rates within 12 months after intervention were compared between the two groups. ResultsBefore intervention, there was no statistically significant difference in systolic and diastolic blood pressure between the two groups (P＞0.05). After 12 months of intervention, the systolic and diastolic blood pressures of the observation group were significantly lower than those of the control group, whereas the seven indicator scores of SF-36 scale in the observation group including physiological function, social function, physiological limitation, physical pain, mental health, emotional function, and energy were significantly higher than those in the control group, with statistically significant difference (P＜0.05). Within 12 months after intervention, the rehospitalization rate of the observation group (10.0%) was significantly lower than that of the control group (26.0%). The difference was statistically significant (P＜0.05). ConclusionOn the basis of medical treatment, dietary guidance intervention in patients with essential hypertension can help patients control blood pressure, improve therapeutic effect and life quality.
