| Objective To explore the method of nurse lead brisk walking on treatment and prevention of hypertension among community olders and evaluate the results, therefore, to obtain some evidence for further guide on the practice of physical activity intervention on treatment and prevention of hypertension among community olders.Methods Two communities were selected as research communities which are no obvious differences economically and geographically in Yinchuan city of Ningxia Hui Autonomous region. After systemic healthy education on hypertension in the two communities, 65 subjects were randomly selected in each of the community according to the include criteria and exclude criteria. Among them, 45 were hypertensive and 20 were high-normal blood pressure. Then the two communities were randomly selected as intervention community and control community.The intervention community was applied nurse lead brisk walking intervention, and the intervention used social cognitive theory as intervention theory and made brisk walking plan for every member. The control community was applied the normal hypertension intervention now applying in other communities. The effects of the interventions were compared after 6 months. The subjects were all kept the eating habits as usual and ate the same anti-hypertension medications (The high-normal blood pressure group did not take anti-hypertension medications).Results①the intervention group all followed the instruction. Among the intervention group of the hypertension, there were 86.36% subjects whose physical cativity level reached the requirement of the guideline for hypertension treatment and prevention of China. Among the intervention group of the high-normal blood pressure, there were 80.00% reached the requirement. As a whole, there were 84.37% subjects whose physical cativity level reached the requirement of the guideline among the intervention group; there were only 26.56% reached the requirement and 51.56% subjects do not do exercise among the control group.②The systolic blood pressure and diastolic blood pressure of the intervention group of the hypertension lowered 11.25mmHg and 9.09 mmHg, respectively. The systolic blood pressure and diastolic blood pressure of the intervention group of the high-normal blood pressure lowered 13.30mmHg and 4mmHg, respectively. Compared with control group, the differences between the two groups were statistically significant (P<0.05).③Among the intervention group of the hypertension:the number of the subjects whose blood pressure under control increased 8(18.18%); the number of the second level hypertension reduced 11(25%); no subject developed to third level hypertension. But there were 7 subjects developed to third level hypertension among the control group of the hypertension. The difference of the level of the hypertension between the two groups was statistically significant (P<0.05).④Among the intervention group of the hypertension: the number of the overweight and obese decreased 4(9.09%)respectively; the number of the visceral obesity reduced 20( 45.45%).Compared with control group, the difference of the visceral obesity of the two groups was statistically significant (P<0.05). Among the intervention group of the high-normal blood pressure: the number of the overweight and obese decreased 7(35.00%)and 2(10.00%)respectively; the number of the visceral obesity reduced 11(55.00%).Compared with control group, the difference of the visceral obesity of the two groups was statistically significant (P<0.05).⑤The number of the subjects with elevated LDL-C level among the intervention group of hypertension and high-normal blood pressure decreased 10(22.72%)and 7(35.00%), respectively. Compared with control group, the difference of the two groups was statistically significant (P<0.05).⑥The mean of the following factors of the quality of life of all the intervention groups increased: Physical symptoms, somatic symptoms, sexual dysfunction, vitality, sleep dysfunction, angry, obsessive-compulsive symptoms, anxiety and depression. Compared with control groups, the differences of the sleep dysfunction of the intervention group of the hypertension and the intervention group of high-normal blood pressure were all statistically significant (P<0.05). Compared with control group, the difference of the physical symptoms and depression of the intervention group of the hypertension were statistically significant (P<0.05).Conclusions The nurse lead brisk walking intervention on treatment and prevention of hypertension among community olders could significantly improve the compliance of physical activity of community olders. It could improve the control of the first level and second level hypertension and prevent the high-normal blood pressure develop to hypertension or delay the process. It is effective for lower weight, especially for the visceral obesity. It also has effect on the prevention of diabetic and decreasing LDL-C level. It could improve the quality of life, especially the sleep dysfunction. |
