Focus Group Discussions (FGDs) were conducted with a subset of the population. The relationship amongst treatment compliance and responses to questions that captured assorted components of the HBM was investigated utilise chi-square tests. Content analysis was employ to analyze data from the FGD sessions and to reserve context to the survey responses. Data entry and management was carried out using the Statistical mail boat for Social Sciences (SPSS) version 11.0.RESULTS The components of the HBM reflecting perceive competency components were evidentially associated with treatment compliance. On the former(a) hand, HBM Per ceived Seriousness components were non significantly associated with compliance. The main HBM Perceived Benefit of victorious Action component that was prominent was the belief that hypertension could be senior by treatment, a theme that emerged from both the survey and the FGD.CONCLUSION Use of the HBM as a model is adjuvant in identifying perceptions and behaviors associated with hypertension treatment compliance.Key words Health belief model Compliance Hypertension Community-based NigeriaCore tip Hypertension is a major health problem in ontogenesis and substantial countries, and treatment compliance for such chronic conditions is often poor. In this study, the Health Belief Model (HBM) was utilise to evaluate care quest and treatment compliance among hypertensive adults. HBM proved to be a invaluable framework to develop and modify public health interventions and in like manner serves to improve treatment compliance and press the risk of complications.Osamor PE, Oj elabi OA. The health belief model and compliance with hypertension treatment. World J Hypertension 2017 basisHypertension, differentwise known as high blood pressure, is a leading cause of cardiovascular distemper (CVD) worldwide1. The proportion of the planetary marrow of unhealthiness attribu tabular array to hypertension has significantly increased from about 4.5 portion (nearly 1 billion adults) in 2000 to 7 percent in 20102-9. This makes hypertension a major global public health challenge and the single some weighty cause of morbidity and mortality globally. The preponderance of hypertension in Nigeria may form a substantial proportion of the total burden in Africa. This is because of the capacious population of the country currently hazardd to be all over 170 million3,6,10. In Nigeria, hypertension is the common landest non-communicable disease with over 4.3 million Nigerians higher up the age of 15 classified as being hypertensive using the erst magic spell natio nal guidelines (systolic BP 160 mmHg and diastolic BP 90 mmHg)12-15.Treatment of hypertension rests on a crew of lifestyle interventions and use of antihypertensive medicinal drug. However, poor compliance with treatment is often common in hypertension. Studies of treatment compliance break explored the role of conglomerate factors, including demographic and socio-behavioral features of patients, the type and source of therapeutic regimen, and the patient-provider relationship16. Yet, a common framework for evaluating such factors is often lacking. genius such framework is the Health Belief Model (HBM),which has basen utility program in evaluating compliance with antihypertensive medications17-20.Health Belief ModelThe Health Belief Model (HBM) is an intrapersonal health behavior and psychological model. This model has been comm only when applied to studying and promoting the uptake of health services and toleration of health behaviors21. Recently, a National Institutes o f Health publication, Theory at a Glance, A Guide for Health Promotion Practices proposed that the HBM may be utilitarian in the examination of inaction or noncompliance of persons with or at risk for heart disease and stroke24, suggesting a natural fit for this study.The HBM is a value-expectancy model 17. It attempts to inform and predict health behaviors by focusing on the attitudes and belief patterns of individuals and groups. The modelconsists of six dimensions comprehend susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action and modifying factors. While the HBM has been criticized for overemphasizing the logical order and rationality of ones health behaviors28, it is considered to be one of the most influential models in the history of health promotion practice29, and has shown usefulness in predicting health behaviors among population with or at risk for developing cardiovascular disease.With respect to care-seeking and treatment compli ance, a hypertensive patients ability to see a physician and comply to medical treatment regimen is a function of a various factors. These imply patients personal knowledge, benefit and perceptions, modifying factors, and cues to action30. Therefore, the goal of this study is to explore the use of the HBM as a framework for evaluating care-seeking and treatment compliance in hypertension in south-west Nigeria.RationaleUncontrolled hypertension is cause by non-adherence to the antihypertensive medication, patients understanding their drug regimens and the necessity to adhere to this regimen will help to improve their adherence, olibanum help prevent the complications of hypertension that are debilitating and if not prevented can increase the burden of a disease that is already on the increase31. Knowledge and beliefs about hypertension have been frequently examined in efforts to go against understand the disparities in blood pressure control33,34. Relatively few studies, however, have attempted to identify individual factors associated with the adoption of hypertension control behaviors using a health behavior model as the a priori framework. Thus, this study aims to explore the use of the HBM- an intrapersonal health behavior and psychological model in evaluating care seeking and treatment compliance among hypertensive adults in south west Nigeria. MATERIALS AND METHODSThis community-based cross-sectional study was carried out in an urban, low-socio-economic community in Nigeria. close to of the residents belong to the Yoruba ethnic group and the dominant religion is Islam. The health facilities in the community include an outreach clinic run by the Department of Preventive Medicine and Primary Care of the University of Ibadan, quadruple private clinics and a small dental clinic. Other sources of health care in the community include Patent Medicine Vendors (PMVs) and three traditional healing homes. The study site was selected for three specialised reas ons Firstly, the community has been the site of prior research studies where people were screened and on that pointfore know of their hypertension status. Secondly, a community study approach (instead of a clinic-based approach) was chosen because selecting participants from a clinic or hospital will only select those who are searching clinic or complying, thereby introducing a selection bias and thirdly, the community has a variety of sources of health care located within the community, implying that residents have options when seeking healthcare.The study is a community-based cross-sectional study which enrolled hypertensive adults (age 25 years and above) in the community. It utilized both the survey and Focus Group Discussion (FGD) to collect primary(a) data from the respondents. The participants for this study were selected from a list of known hypertensive adults residing in the community that was developed from a previous hypertension study35 and updated for the present s tudy during home visits. Four hundred and forty (440) hypertensive subjects were enrolled using a consecutive sampling method.After obtaining informed consent, subjects were administered a semi-structured questionnaire that had items on several issues, including knowledge on causes, prevention and severity of hypertension, healthcare seeking for hypertension, their beliefs and perception about hypertension and compliance with treatment including safekeeping clinic follow-up appointments and on a regular basis taking their antihypertensive medications. Eight FGDs were conducted, each with 6-8 discussants. The dimensions of the HBM were operationalized as described in table 1, where each dimension was framed as a series of questions, which were bespeaked in the survey and/or discussed as a topic in the FGD.Data entry and management was carried out using the StatisticalPackage for Social Sciences (SPSS) version 11.036. Univariate analyses were employed in understand socio-demographi c characteristics of the respondents, while a bivariate analysis was used in cross tabulating variables. The transcription of the qualitative data was carried out immediately after each FGD session. This was inseparable since the memory of the interviewer/note taker was still fresh and it was easier to reconcile written notes and the interview transcripts. Content analysis was used to analyze data from FGD sessions.RESULTSSocio-demographic characteristicsA total of 440 (including 287 women) respondents were studied. The ages of respondents ranged from 25 to 90 years, with a mean of 60 (SD 12) years. Most (71%) of the respondents were married and 61.4%, Muslims. Slightly over half of the respondents (51.1%) had no formal education. About half (50%) of the respondents were traders, while those who have retired and not working constituted 25.7%.Prevalence of compliance with clinic visits and taking medicationThe prevalence of self- account compliance with clinic appointments was 77.5% and that of keen compliance with treatment was 50.7% of respondents. 41.5% reported poor treatment compliance at variant levels ranging from regularly abstracted taking their medication to fairly regularly, some metres and rarely taking their medication.Perceived Susceptibility to hypertensionIn response to being asked what they understood by the disease hypertension, most respondents defined hypertension as an nausea of anxiety and striving (60.9%). Nearly one in twelve (7.3%) said they did not know what hypertension meant. A few of the respondents (4.1%) desired that hypertension means too much blood in the body, thereby causation tension in the blood. Roughly two percent of respondents said hypertension was in e verybodys blood. A iterate from one of the FGDs is illustrativeHypertension is in everybodys body and blood. When we exert undue stress on our body, sound off too much and do a bus of wahala (stressful things), hypertension will start.This statement clearly art iculates the feeling that everyone is predisposed to hypertension but the condition only becomes apparent or manifests itself when the person experiences a messiness of stress. This could either mean that everyone is predisposed to having hypertension or that hypertension is hereditary.Perceived Severity of hypertensionA large proportion 89.8% of the respondents knew that hypertension could lead to other serious health problems or complications. Only 1.1% did not affirm that it will lead to serious problem, while 9.1% did not know if hypertension could lead to other health problems. Other health problems that could result from hypertension mentioned by respondents include stroke (47.5%) expiry (25.5%) prankish headache (5.2%) and heart attack (5.0%). In the FGD sessions conducted, respondents were asked if they perceived hypertension to be a serious health problem. The general response was that hypertension is a serious health problem. One of the FGD discussants summed it this w ayHypertension is a very serious sickness. It is not sickness we should take lightly. It can lead to quick death. One of my younger brothers who worked in the bank had hypertension. He suffered attacked from hypertension while in the office and before they got to the hospital, he died. Hypertension kills fast. But it has drugs that can control it and if one is not taking the drugs regularly, it will cause serious problem.A fifty-two years old woman used her personal experience to buttress the magnitude of hypertension. She say thatThis sickness they call hypertension is a very serious sickness. I was not taking either drugs because I did not have money to buy it and I was not worried because I was not feeling sick. In 2003, I was sick just for a week and before I knew what was occurrence I could not walk or move my body. I was rushed to the hospital and they told me my blood pressure was very high. I was in the hospital for almost a month and my children spent a lot of money. I a m reveal now, but am still using walking stick because the hypertension made my body stiff. I am taking my medication always now so that I do not die quickly because it can kill.The general perception of the respondents and focus group discussants on the complications from hypertension is that hypertension itself is a very serious health problem and that any complications arising from it could be very severe.Perceived benefit of treatment complianceNearly three quarters (73.2%) of the respondents intendd that hypertension could be cured with treatment. Most (72.0%) of the respondents reported that it is not thoroughly to wait until one feels sick before taking antihypertensive medication and the reason given by a large proportion (30%) of these respondents is that taking medication regularly will prevent reoccurrence of hypertension. Despite the fact that respondents believe they needed to take medication as official (and not only when they are sick), only a relatively small prop ortion (a minute above 50%) of the respondents did take their medication as prescribed.Perceived barriers to complying with treatmentAmong the respondents, 41.5% had poor compliance at different levels ranging from regularly missing taking their medication to fairly regularly, some judgment of convictions and rarely taking their medication. Of these respondents who were non-compliant with their medication, 11.4% said they mat better and therefore had no need to continue taking their medication. Only 0.5% said they were tired of taking drugs, while 6.8% stopped because of lack of funds to purchase drugs. Other factors included side effects of drugs (6.1%), forgetfulness (8.4%), busy schedule and peculiar(a) medication (3.6%). A major theme from the survey and FGDs is that respondents were apprehensive of the long terminal figure effects from antihypertensive medication and the possibility of being stuck with it for the rest of ones life or the medication cause other illness or complications. Negative feelings were elicited in some cases, as antihypertensive drugs were perceived as being damaging or not good for the body. The FGDs highlighted factors that hindered good compliance to treatment patronage the general acceptance of the necessity to take antihypertensive medications. One of the discussant saidI do not take my medicine every day. People do not always follow what doctor say. It is not only for hypertension, even for other sickness. If they say take medicine for five days, once we feel better by thethird day, the person will stop. Even the doctors themselves, will they swallow medicine every day?A discussant in another session statedLet me tell you the truth it is not easy to be taking drugs every day. Sometimes, we forget especially when you are rushing to go out. Sometimes we do not have the money to buy it.Another respondent added details about what often happens as a result of the financial obstaclesThat is what we have all been trying to say . Money is the major problem. In the hospital, they will ask you to pay for ordinary card, before you see the doctor. When they write drugs for you there is no money to buy all. If you do not have money and you go to a private hospital, they will not even attend to you. That is why some people prefer to just go to chemist and buy what they can cave in and some others prefer traditional medicine because you do not have to drink it every day and it is less expensive.Cues to actionAn important source of cues to action includes the individuals cultural conditioning of available treatment options. In this study family and friends were a major source of cues to action. Overall, 19.3% of respondents reported that family members were very concerned about their hypertension while 74.8% said family members were passing concerned about their hypertension. Also, 20.2% and 73.2% respectively reported that family members were very helpful or passing helpful in reminding them about taking their medication. Regarding support from friends, 26.4% of respondents reported that friends were very concerned about their hypertension while 28.9% said friends were extremely concerned about their hypertension. Out of the 440 respondents, 91 and 150 (20.7% and 34.1%) respectively reported that friends were very helpful or extremely helpful in reminding them about taking their medication (Figure 1). treatmentHypertension is a condition of sustained high blood pressure which can only be confirmed after blood pressure measurements that meet the criteria for the condition. The cause of hypertension is not known in most cases1 hence the term essential hypertension. In the present study, hypertension is perceived primarily as an illness of anxiety and stress. This finding is consistent with a previous study of hypertension in Nigeria38 which revealed that over 60% of their respondents irrespective of the educational background believe that psychosocial stress is the main cause of hypertensi on. Similarly, Koslowsky et al39 found that stress and tension were most commonly stated as causes of hypertension. Majority (more 90%) in this study believe hypertension is a serious condition and two-thirds (66%) believe that hypertension can be prevented. Contrary to findings and reports from previous studies38,40,41, nearly three-quarters (73%) of respondents in the present study believe that hypertension is curable. Almost half of the respondents vociferation good compliance with respect to drug treatment and 86% claim good compliance with keeping their doctors appointment. Reasons for compliance to treatment include fear of the complications of hypertension and the desire to control blood pressure. Benson and Britten42 reported that patients comply with medication regimen for a variety of reasons including perceived benefits of medication fear of complications associated with hypertension and feeling better on medication. The latter reason is contrary to the generally held be lief among physicians that hypertension is a largely asymptomatic disease43.One central theme that runs through the data in this study is the issue of socio-economic status of the respondents. This suggests the importance of considering other variables that can help form individuals perception including health care costs and some sort of drop consultation that takes place before they resolve to take a recommended health action27. Financial hardship is a barrier which should not be ignored as it is a contributory factor to noncompliance. This finding corroborates the find association between poor compliance, ignorance and lack of funds for purchase of drugs44. Failure of patients to keep scheduled appointments is an important obstacle to the provision of effective healthcare. By missing appointments, individuals deprive themselves of professional services. Interestingly, 77.5% of the respondents in this study claim they comply with keeping their follow up clinic appointments every time. Several studies have investigated HBM and appointment-keeping for chronic disease management. Nelson et al20 and also Landers et al45 found HBM variables to be unrelated to keeping clinic appointments for hypertension.Social support networks are important in the semipermanent management of chronic conditions such as hypertension, which require a radical and life-long change in the lifestyle of the affected person. In this study, those who had support from friends or family members (concerned about their illness, giving reminders about medication) showed better treatment compliance than those who did not, although this difference was greatest for those that had the support of friends. This is an important finding and is consistent with what has been reported for multiple chronic diseases in several parts of the world46.A summary of the major findings in this study in the context of interpreting compliance using the significant components of the HBM shown in Figure 1 suggests th at HBM Perceived Susceptibility components tested were significant predictors of compliance. On the other hand, HBM Perceived Seriousness components were not significantly associated with compliance. The main HBM Perceived Benefit of Taking Action component that was prominent in this study is the belief that hypertension can be cured. This is a recurring theme in all the components of the study (survey and FGD) and most respondents believed that taking the medication for some time led to a cure and one could stop taking medication. This finding agrees with studies of Kamran et al47, which showed a relationship between HBM constructs and treatment compliance. The constructs that were significantly showing relationship in their study were perceived susceptibility, perceived benefit of using the medicine and perceived barrier to treatment. This has major personal and public health implications because hypertension can only be controlled (not cured) and stopping medication can lead to c omplications. More importantly, it highlights the discrepancy between healthcare providers and their patients in the perceived goal of treatment since the former are working towards control while the latter believe compliance can lead to cure.Most of the HBM Barriers to Taking Action components emerged during the FGD sessions. These barriers are practical issues that loom large and prevent the patients from making optimum use of the hospitals and medications that are available. In other words, the option of a university didactics hospital is available but is not accessible because of costs and inconvenience. Similarly, known medications that work well in hypertension are available but the costs are too high for the patients to comply with the prescriptions as written. It is noteworthy that believing that one can stop taking the medication after some time can also serve as a barrier to compliance because the individual now believes there is no need for more medication.Another major finding from this study is that HBM Cues to Action are extremely important in predicting compliance with hypertension treatment in this community. These cues are centered on patients having family members and/or friends who are concerned about the individuals health and treatment. This finding is important because, as noted by Harrison et al48 in a meta-analysis, cues are often not included in Health Belief Model studies. Indeed, these authors limited their review to articles to the four major components of the HBM (susceptibility, severity, benefits and costs) because in their words Cues to action have received so little attention in empirical studies that we excluded this dimension. However, the findings of this study shows that cues are an important dimension in these types of study. While the specific cues that are important may vary between locations, cultures, and environments, they emphasize the social context in which health behavior takes place. As expected, attending clini c regularly is an important predictor of compliance in the present study. It provides an luck for multiple cues that can improve compliance, including blood pressure checks, discussing actions to control blood pressure, and reminders to take medication.CONCLUSIONComponents of the HBM show variation in association with treatment compliance for hypertension in this Nigerian community. The findings provide useful baseline data for future studies of the Health Belief Model in hypertension and other chronic conditions in similar societies.Strength and limitations of the studyStrengths of this study include the use of both survey and FGD methods cellular inclusion of a large set of variables and focus on the components of the HBM to a non-communicable disease (hypertension) in a developing country context. A potential limitation is that the study did not formally investigate the modifying factors dimension of the HBM. Nonetheless, the findings provide clues to care-seeking and compliance issues, while suggesting potential intervention points (e.g. breaking the cost barrier, including social networks in treatment plans) that could be further studied and tested. good ApprovalEthical approval for the study was obtained from the Joint University of Ibadan /University College Hospital Ethical Committee.AcknowledgmentThe authors are grateful to the study participants and community leaders of Idikan community, Ibadan.
