Purpose: To examine the effectiveness of goal-based health management on health knowledge, health belief and health behavior in people at high risk of stroke.
Patients and Methods: This is a two-armed and non-randomized controlled trial from May 31, 2020 to December 31, 2020. Participants were arranged to receive regular health care (n=126) or goal-based health management (n=126). The generalized estimation equation was used to analyze the changes in the participants’ health knowledge, health belief and health behavior at baseline (T0), 1-month (T1), 3-month (T3), and 6-month (T6).
Results: A total of 243 participants completed the 6-month study, of which 123 were in the control group and 120 were in the intervention group. After receiving goal-based health management, participants’ health behavior (β= 27.154, p< 0.001), health knowledge (β= 10.504, p< 0.001) and health belief (β= 49.057, p< 0.001) scores increased significantly.
Conclusion: Goal-based health management can effectively improve the health knowledge, health belief and health behavior of people at high risk of stroke. We recommend that nurses can provide goal-based health management for people at high risk of stroke with support from hospitals and family members of people at high risk of stroke.

Stroke has always been a global concern that cannot be ignored. Although the prevalence of stroke has declined, the aging of the population and the cumulative risk factors have led to an increased lifetime risk of stroke.1,2 The global average lifetime risk of stroke increased from 22.8% in 1990 to 24.9% in 2016.3 About 2.4 million people are diagnosed with stroke and 1.1 million die from the disease each year, with more than 11.1 million stroke patients in China every year.4
There are eight major risk factors for stroke in China: history of hypertension, diabetes, hyperlipidemia, heart disease or atrial fibrillation (AF); family history of stroke; obesity; lack of physical exercise; and smoking. People over 40 years old, with three or more factors, or with a history of stroke or transient ischemic attack (TIA) can be considered at high risk of stroke.5 Fortunately, long-term health behavior has been shown to reduce the incidence of stroke to less than 10%.6 And a cross-sectional survey shows that health knowledge and health belief are the influencing factors of health behavior.7 It is necessary to strengthen public education, screen those at high risk of stroke who need targeted treatment, and control risk factors by promoting a healthy lifestyle.8
Health management originated in the United States, where commercial medical insurance plays an extremely important role.9 The purpose of health management is from “disease intervention” to “disease prevention” and from “treatment of symptoms but not the cause of disease” to “treatment of both symptoms and cause”.10 Since the concept of health management was introduced into China at the end of the 20th century, it has been developed obviously in theoretical education and industrial practice.11 To explore a new health management mode, the National Stroke Prevention and Treatment Engineering Committee launched the cultivation program for stroke health managers (renamed as brain and heart health managers in 2018) in 2017, aiming to provide pre-hospital, in-hospital and post-hospital health management services for people at high risk of stroke (including patients with a history of stroke) with hospital support.12 The main responsibility is to conduct systematic, standardized and individualized scientific management for people at high risk of stroke through systematic cultivation, so as to reduce the incidence rate and recurrence rate of stroke.13
Previous health management programs do not seem to consider helping participants set goals.14–17 There is a review suggesting that setting goals can promote health behavior.18 The connotation of Goal Setting Theory is that when people promise and work hard for the goal, it is possible to achieve the desired result.19 Walker and Avant believed that the goals should have five characteristics: clarity; reality; quantification; time limit; and related to the desired result.20 Goals are divided into internal goals and external goals. Individuals pursuing internal goals (eg physical health and hedonism) are more likely to engage in activities that can lead to positive behavioral outcomes; while individuals pursuing external goals (eg financial success and popularity) has the opposite effect.21
The Goal Setting Theory points out the direction for the health management of people at high risk of stroke, while the Ecology of Health guides the process of health management. Ecology of Health advocates that individual health is the result of the interaction between individual and environmental factors.22 This theory believes that it is not only personal characteristics and lifestyle that can affect personal health, but also external environment, medical health, interpersonal culture and other factors.23 Our health management is jointly participated by one hospital, three communities, families, and individuals. Brain and heart health managers connected each part as a “bridge” in the process.
Patients and Methods
To analyze whether goal-based health management can improve the health knowledge, health belief and health behavior in people at high risk of stroke.
This paralleled and non-randomized controlled trial from July 1, 2020 to December 31, 2020 was conducted in 3 communities in Zhengzhou City, Henan Province, China (30 people at high risk of stroke participated in the preliminary trial in June 2020.). Participants who are quarantined due to the prevention of the Corona Virus Disease-19 cannot participate in group meetings or activities and they were included in the controlled group. This study was registered before implementation (Clinical Trials. ChiCTR2000032817).
Health Management Team
The health management team in this study was composed of neurologists (n=2), brain and heart health managers (neurology nurses) (n=4), rehabilitation therapist (n=1), contracted services of family doctors (community physicians) (n=4), and community health nurses (n=4). Neurologists, brain and heart health managers (neurology nurses) and the rehabilitation therapist were from the same hospital. The brain and heart health managers led the management activities of the entire team and they were responsible for helping contact team members.
During the trial, neurologists, contracted services of family doctors and rehabilitation therapists were invited once a month to preach the knowledge of stroke disease to the control group members through Tencent Meeting (an online conference tool, which can be linked through WeChat). There were two courses in each meeting, each lasting approximately one hour. At the end of each meeting, we distributed related health manuals to the control group participants (Appendix 1 shows the contents of courses).
Goal-Based Health Management
First, the health management team set goals based on previous research.7 Then face-to-face interviews were conducted with 10 people at high risk of stroke (not included in the intervention group) and the goals were set (Appendix 2 shows the contents of the interview). Finally, “Health management every day to keep stroke away” was taken as the final goal of health management. “Know yourself and know stroke”, “Well begun is half done”, “Stroke can’t be prevented in one day” were taken as the themes at each stage of health management.
Know Yourself and Know Stroke
This stage lasted for a month. The goal was to enable people at high risk of stroke to acquire knowledge related to stroke diseases and prevention of stroke, as well as to fully understand their situation. In addition to providing knowledge of stroke disease to the intervention group participants every week, the health management team also assessed the health status of each participant and informed them of precautions. This increased the interaction and communication between researchers and participants, and could more effectively help participants solve health problems.24
Well Begun is Half Done
This stage lasted for two months. The purpose was to encourage people at high risk of stroke to actively participate in health management. During this period, in addition to imparting stroke-related chronic disease management knowledge, the health management team also organized participants to share health management experience. Team members, participants, and participants communicate with each other through WeChat. Brain and heart health managers followed up the participants by telephone every two weeks to help them solve the problems encountered in the health management process in time. Telephone follow-up could potentially increase the enthusiasm of people at high risk of stroke to participate in health management.25
Stroke Cannot be Prevented in One Day
This stage lasted for three months and aimed to supervise and promote the adherence to health management of people at high risk of stroke. In this stage, the competition was added based on the intervention methods of the previous stage, and people at high risk of stroke who actively participated in health management were praised and rewarded. This might encourage people at high risk of stroke to adhere to health management.26 (Appendix 3 supplements the detailed intervention content; supplementary video 1 and Supplementary video 2 are used to show researchers’ efforts to promote the ability of people at high risk of stroke to identify acute stroke and maintain a healthy diet.)
Inclusion and Exclusion
The following population were included in this study: a. beyond the age of 40 years; b. having three or more risk factors, or having a history of stroke or TIA (mentioned in the introduction); c. having clear consciousness to complete the research; d. agreeing to participate. People at high risk of stroke with other serious acute or chronic diseases were excluded.
Health behavior was used as the main indicator to calculate the sample size in this study. The results (X1 =100.26, X2 =105.34, σ=17.57) of preliminary trial in 30 people at high risk of stroke were uploaded to a website that calculated the sample size (http://powerandsamplesize.com/Calculators/). The sample size was calculated to be 188 cases. Considering that there may be a 15% sample loss rate, the sample size was estimated to require at least 221 cases.27 Finally, we recruited 252 participants.
The results of the study were collected before the intervention (T0), 1-month (T1), 3-month (T3), and 6-month of the intervention (T6). Four trained researchers collected data through phone calls or face-to-face interviews. No hints are made to participants during the collection process. Take it back immediately after the participants complete the questionnaires. One-to-one collection of data ensured the integrity and reliability of the data. The data was entered into the computer in parallel by two researchers and others randomly checked the data before the analysis.
Outcomes and Measurements
Demographic variables: age, gender, spouse status, education level, capita monthly household income, sleep duration, family history of stroke, history of transient ischemic attack (TIA)/ stroke, hypertension, diabetes mellitus; dyslipidemia; coronary heart disease; overweight or obesity (BMI>26kg/m2); smoking; drinking and few physical activities. The 9-year of formal education was used to divide the education level. It’s a unique demarcation standard of education in China. Because tuition does not need to be paid for 6 years until high school.
The Stroke Prevention Knowledge Questionnaire (SPQ) was developed by Sun Yat-sen University in China.28 The questionnaire includes 36 items and 8 dimensions, namely daily life (8 items), exercise (4 items), diet (4 items), stroke risk factors (5 items), medication (5 items), blood pressure monitoring (2 items), stroke signs (6 items), stroke management (2 items). Each item has two options: “Know” or “Don’t know”. “Know” counts 1 point, “Don’t know” counts 0 point. This questionnaire has been widely used to investigate the health knowledge of stroke patients and confirmed that Cronbach’s alpha coefficient is 0.791.
The Champion Health Belief Model Scale (CHBMS) in the Chinese version has 33 items and 6 dimensions, including perceived susceptibility (5 items), perceived seriousness (6 items), perceived benefits (6 items), perceived barriers (6 items), health cues to action (5 items) and self-efficacy (5 items).29 The scale uses a Likert five-level scoring method, ranging from “completely disagree” to “completely agree” with a score of 1–5. The higher the score, the higher the belief in taking corresponding health behavior. The Cronbach’s α coefficient of the scale is 0.833.
The Health Promoting Lifestyle Profile II (HPLP II) is revised based on the HPLP.30 It was translated into Chinese and promoted to measure the health behavior of people at high risk of stroke.28 The scale includes 52 items and 6 dimensions: health responsibility (9 items), exercise (8 items), nutrition (9 items), self-actualization (9 items), interpersonal relationship (9 items) and stress response (8 items). Each item on the scale uses a Likert 4-level scoring method, ranging from “never” to “always” on a scale of 1–4 points, with a total score ranging from 52 to 208 points. The higher the score, the better the health behavior. This scale has good reliability and validity in China.31
This experiment was approved by the ethics committee of the First Affiliated Hospital of Zhengzhou University (2018-KY-356). Participants were informed of the purpose and time of the trial before recruitment. Then they agreed to participate the trial through written documents. Participants had the right to withdraw at any time during the trial. Their personal information was stored in a computer folder with a password. And there will be no descriptions that can reveal the identity of the participants in the manuscript. This study was conducted in accordance with the Declaration of Helsinki.
The results were statistically analyzed using IBM SPSS Statistics 21.0 software. The demographic characteristics of the participants were described by mean ± standard deviation (x ± s), frequency and percentage. Scale scores were described by mean ± standard deviation (x ± s). The differences between the two groups were compared through the Generalized Estimating Equation model (GEE). For repeated measurement data in clinical trials, the generalized estimation equation can effectively consider intra-group correlations and deal with data with missing values, which can evaluate health management effects more objective.32
A total of 243 participants completed the 6-month study, of which 123 were in the control group and 120 were in the intervention group. The study flow is presented in Figure 1. Most of the participants were male, which is consistent with the characteristics of stroke disease in China.33 In this study, the age of the participants was high (range: 41–84 years, average age: 63.26±11.15) and the level of education was low (56.8% received less than 9 years of formal education). A small number of participants have a family history of stroke (19.8%) or a history of TIA (16.0%). Hypertension (58.5%) is the largest proportion of all risk factors among participants who completed this study. Table 1 lists the demographic characteristics of the population at high risk of stroke in the control group and the intervention group. There was no significant difference between the two groups of participants.

The effects of health management on the health knowledge, health belief and health behavior of people at high risk of stroke are represented by a Generalized Estimation Equation Model. The reference categories are the control group and the baseline values. Table 2 shows the mean and standard deviation of the health knowledge, health belief and health behavior of the two groups of people at high risk of stroke at the four measurement time points (T0, T1, T3, T6). After one month of goal-based health management, there were no significant differences in the scores of health behavior (β=2.279, p=0.641) between the two groups. After 6 months of health management, the average health behavior score of the control group rose from 101.24 to 119.56, and the intervention group rose from 101.48 to 140.00 (β=27.154, p<0.001). The health knowledge (β=10.504, p<0.001) and health belief (β=49.057, p<0.001) of participants in the intervention group also have been significantly improved.
Table 2 Effectiveness of Goal-Based Health Management on Health Knowledge, Health Belief and Health Behavior
Goal-based management can promote the communication between managers and the managed and improve the effectiveness of problem solving.34 The goals for the three different stages of health management are determined by the researchers in collaboration with the participants, which can ensure the quality of the goals.35 The intervention aimed to enable people at high risk of stroke to adhere to health management to prevent stroke. The goal of each stage was consistent with this ultimate goal, which helped participants gradually receive health management. Measurement indicators and questionnaires helped researchers determine whether participants have achieved the goals of each stage. Our three goals are clear, time-limited, achievable, measurable, and consistent with expected results, which may be beneficial to health management.18
In this study, after one month, the health knowledge scores of the two groups of participants were not statistically different from the baseline. The reasons may be as follows: according to the arrangement, the two groups did not complete all courses in the month; participants did not use knowledge to maintain health. Knowledge can guide health behavior.36 In turn, health behavior can help participants better receive health knowledge.37 Health belief is the driving force of health behavior.38 Effective improvement of knowledge, belief, and behavior is the most basic requirement of health management for people at high risk of stroke. The change of health behavior is of great significance to the improvement of health management.39
In this study, the health behavior of the two groups was improved at the end of the trial, but the scores of the participants who received goal-based health management increased more significantly. This provides evidence that goal-based health management has a positive impact on the health behavior of people at high risk of stroke. In the baseline measurement, in terms of the intervention group, people at high risk of stroke had the highest scores on the nutrition dimension (20.33±3.47), followed by interpersonal relationship (18.70±4.89), self-actualization (17.98±4.50), health responsibility (17.80±4.77), and stress response (13.80±4.02). The lowest score was on the exercise dimension (12.88±3.28). After 6 months of goal-based health management, the participants scored the highest in interpersonal relationship (28.60±4.37), while the exercise dimension scored still the least (18.53±3.94). We analyzed the reasons for this change. WeChat and Tik Tok were used to help researchers connect with participants and to share health information. Internet social platforms enhanced the communication effect and enabled participants to obtain emotional support, which may be related to the changes in the participants’ interpersonal relationship dimension scores.40 The lowest score in the exercise dimension may be due to the fact that people at high risk of stroke are generally older (age: 63.85±10.62 years), ie, older people unable to maintain enough time or fail to achieve moderate intensity during physical exercise due to illness or fission.41 Moreover, the scores of nutrition dimension after intervention (25.73±3.62) indicated that people at high risk of stroke have the consciousness to choose a low-salt and low-fat healthy diet. This is consistent with previous research.42,43
There are some limitations to this study. Firstly, due to the impact of the COVID-19, this study only selected 3 communities in the central region of China. If the goal-based health management in this study is extended to other cities or even other countries in the future, there may be different results. Then, due to the weather, we occasionally followed up by phone instead of face-to-face. Since information can only be exchanged over the phone, the researchers cannot directly observe the health status of the participants. However, there is evidence that telephone follow-up is valuable.44 Although the two follow-ups may cause slight differences, our results are still reliable. Finally, this study was designed as a non-randomized controlled trial, which may be difficult to ensure uniformity between the groups before intervention. To increase the reliability of the sample, we have increased the number of people at high risk of stroke selected as much as possible.
In this study, goal-based health management was led by brain and heart health managers, hospitals and communities jointly for people at high risk of stroke. Social media platforms were used in the management process. The health knowledge, health belief and health behavior of the participants in the intervention group were significantly improved compared with the control group. We recommend that medical professionals set goals when implementing health management for people at high risk of stroke.
