Comparisons of Stroke Knowledge and Health Behaviors in Patients With Hypertensive Stroke at Different Recurrence Risk Strata: The Comprehensive Reminder System Based on the Health Belief Model Study.

BACKGROUND: Risk factor management via behavioral change contributes substantially to secondary stroke prevention. The health belief model identified self-perceived risk as a significant factor in behavior change. In previous studies, people have tended to incorrectly estimate their risk of stroke. Little is known about the differences in stroke knowledge and health behaviors in patients who have had a stroke with different risks of stroke recurrence in China. OBJECTIVE: The aims of this study were to determine the accuracy of self-perceived risk of stroke recurrence and to compare stroke knowledge and health behaviors in patients with hypertensive stroke at different recurrence risk strata. METHODS: Baseline data from 174 patients in the Comprehensive Reminder System based on the Health Belief Model (CRS-HBM) study were used. Self-perceived risk was assessed via the susceptibility subcategory of the Short-Form Health Belief Model Scale, and actual risk was stratified using the Essen Stroke Risk Score. RESULTS: Only 27.0% of the patients estimated their risks of stroke recurrence accurately. Patients who perceived themselves to be at higher risk had better knowledge of warning signs. Compared with patients who underestimated their risk of stroke recurrence, those who accurately estimated or overestimated their risk less likely to smoke. CONCLUSIONS: Most patients incorrectly estimated their risk of stroke recurrence. Communicating with patients about their future risk of recurrent stroke may help improve their stroke knowledge and health behaviors. Implementation of the Comprehensive Reminder System based on the Health Belief Model focusing on risk education aimed at prevention of stroke recurrence is warranted in China.

The Efficacy of a Comprehensive Reminder System to Improve Health Behaviors and Blood Pressure Control in Hypertensive Ischemic Stroke Patients: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVE: The health behaviors of hypertensive stroke patients in China are not satisfactory. In this study, we tested the effect of a Health Belief Model Comprehensive Reminder System on health behaviors and blood pressure control in hypertensive ischemic stroke patients after occurrence and hospital discharge. METHODS: A randomized, parallel-group, assessor-blinded experimental design yielded participation of 174 hospitalized hypertensive ischemic stroke patients. The intervention consisted of face-to-face and telephone health belief education, a patient calendar handbook, and weekly automated short-message services. Data were collected at baseline and 3 months after discharge. RESULTS: Three months after discharge, the intervention group showed statistically, significantly better health behaviors for physical activity, nutrition, low-salt diet, and medication adherence. The intervention group also had statistically, significantly decreased systolic blood pressure and increased blood pressure control rate. Smoking and alcohol use behaviors were not affected. CONCLUSION: At 3 months, use of the Comprehensive Reminder System based on the Health Belief Model, yielded improvement in most health behaviors and blood pressure control in hypertensive ischemic stroke patients. Continued implementation of this intervention protocol is warranted to determine the long-term effect. Smoking and alcohol use behaviors need to be targeted with a different intervention.

Stroke prevention knowledge and prestroke health behaviors among hypertensive stroke patients in mainland China.

BACKGROUND AND OBJECTIVES: Individuals with hypertension are at risk of stroke, and patients with stroke histories are at risk of experiencing another stroke. At this time, however, only a few studies have reported on stroke prevention knowledge and health behaviors among hypertensive patients who have had an initial stroke. The purpose of this study was to determine stroke prevention knowledge and health behaviors and to analyze the association between these 2 variables among hypertensive stroke patients who have had an initial stroke. SUBJECTS AND METHODS: With the use of a descriptive correlational design, a sample of 112 hypertensive stroke patients was recruited from the departments of neurology of 3 hospitals in Guangzhou, China. Each patient completed 2 reliable, validated questionnaires, the Stroke Prevention Knowledge Questionnaire and the Health Promoting Lifestyle Profile II. Data were collected during patients' hospital admission for stroke, within 2 days of stroke onset, and before they received stroke education. Pearson correlation coefficient was used to examine the correlations between the study variables. Multiple stepwise regression analysis was used to predict both the level of knowledge relating to stroke prevention and health behaviors. RESULTS AND CONCLUSIONS: The participants showed a relatively low level of stroke prevention knowledge and a moderate level of engagement in healthy behaviors. Pearson correlation coefficient between these 2 variables was 0.423 (P < .001). The results of multiple regression analysis showed that stroke prevention knowledge was positively influenced by education level; health behaviors were positively influenced by both gender and stroke prevention knowledge. Findings suggest that male hypertensive patients and those with a lower education level need targeted stroke education. Because knowledge was unrelated to behavior with respect to smoking, alcohol use, and low-salt diet, behavioral interventions should be explored to address these important risk factors among patients at risk for stroke.

Gender Difference in the Association Between Stroke Knowledge and Health Behavior Before the Onset of Stroke Among Chinese Hypertensive Patients.

ABSTRACT: BACKGROUND: Previous research has shown that men and women have different levels of stroke knowledge and differing health behaviors, which are important factors affecting blood pressure, as hypertension is a key risk factor for stroke occurrence. There has been little research on the effects of sex on the association between these 2 variables before the onset of stroke among Chinese hypertensive patients. METHODS: A cross-sectional study and a convenience sampling method were used. 272 male and 118 female hypertensive stroke patients were recruited. Each patient completed the Stroke Knowledge Questionnaire and the Health Behavior Scale for stroke patients. RESULTS: Compared with female patients, male patients had greater stroke knowledge and worse prestroke health behavior. The Pearson correlation coefficient between stroke knowledge and prestroke health behavior was 0.149 and 0.223 in male and female participants, respectively, P < .05. The results of a multiple regression analysis showed that Chinese hypertensive stroke patients' prestroke health behavior was significantly influenced by sex and stroke knowledge. CONCLUSION: Chinese male and female hypertensive stroke patients had disparities in stroke knowledge and prestroke health behavior; moreover, the correlation between these 2 variables before experiencing a hypertensive stroke was different between men and women. Men with hypertension should be considered at a higher risk for an initial or recurrent stroke. Developing sex-specific intervention for primary or secondary stroke prevention in China is essential.

Combined therapy with methylprednisolone and ulinastatin in experimental autoimmune encephalomyelitis.

BACKGROUND: Our previous study had demonstrated that ulinastatin (UTI) had a neuroprotective effect in experimental autoimmune encephalomyelitis (EAE). Methylprednisolone has been recommended to be a standard drug in multiple sclerosis (MS) therapies. The present study was to investigate the protective effects of UTI combined methylprednisolone in EAE. METHODS: Mice were divided into a UTI treatment group, a methylprednisolone treatment group, a combined treatment group with UTI and methylprednisolone, a normal saline treatment group, and a normal control group. EAE mice were induced in groups receiving different combined treatments, or respective monotherapies. Demyelination was evaluated by Solochrome cyanin staining. 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)/ myelin basic protein (MBP)/ the precursor form of nerve growth factor (proNGF)/p75/ inducible nitric oxide synthase (iNOS) proteins in cerebral cortex of EAE were detected by Western blotting. RESULTS: The combined treatment group had a lower clinical score (0.61 ± 0.06) and demyelinating score (1.33 ± 0.33) than the groups with normal saline (clinical score: 1.39 ± 0.08, P < 0.001; demyelinating score: 2.75 ± 0.49, P < 0.05) or monotheraphies. Compared with the saline treated EAE group, UTI combined methylprednisolone significantly increased expressions of CNP (1.14 ± 0.06 vs. 0.65 ± 0.04, P < 0.001), MBP (1.28 ± 0.14 vs. 0.44 ± 0.17, P < 0.001), and decreased expressions of proNGF (1.08 ± 0.10 vs. 2.32 ± 0.12, P < 0.001), p75 (1.13 ± 0.13 vs. 2.33 ± 0.17, P < 0.001), and iNOS (1.05 ± 0.31 vs. 2.17 ± 0.13, P < 0.001) proteins in EAE. Furthermore, UTI combined methylprednisolone could significantly upregulate MBP (1.28 ± 0.14 vs. 1.01 ± 0.15, P < 0.05) expression and downregulate iNOS (1.05 ± 0.31 vs. 1.35 ± 0.14, P < 0.05) expression compared to methylprednisolone treatment EAE group. And proNGF expression was significantly lower in combined treatment (1.08 ± 0.10) than that in UTI (1.51 ± 0.24, P < 0.05) or methylprednisolone (1.31 ± 0.04, P < 0.05) treatment group. CONCLUSION: Combination treatment of UTI with methylprednisolone was shown to protect EAE, suggesting that combination therapy is a potential novel treatment in MS.
