Effect of Community Blood Pressure Self-Monitoring Education on Blood Pressure Monitoring Practices among Adults in Nigeria

Abstract

Hypertension is a major public health concern in Nigeria and an important risk factor for cardiovascular disease, stroke, kidney disease, and premature mortality. Many adults with elevated blood pressure may remain unaware of their blood pressure status because of inadequate routine monitoring and limited access to preventive healthcare services. Community blood pressure self-monitoring education provides an opportunity to improve adults' knowledge and skills in measuring, recording, and interpreting blood pressure readings appropriately, while encouraging regular monitoring and timely healthcare seeking. However, limited awareness, incorrect measurement techniques, inadequate access to validated blood pressure devices, financial constraints, and poor follow-up may affect effective self-monitoring practices. Against this background, this study investigates the effect of community blood pressure self-monitoring education on blood pressure monitoring practices among adults in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and Self-Efficacy Theory. The Health Belief Model explains how adults' perceptions of susceptibility to hypertension and its complications, perceived severity, perceived benefits of regular blood pressure monitoring, perceived barriers, and cues to action may influence monitoring behaviour. Social Cognitive Theory emphasizes observational learning, behavioural modelling, reinforcement, environmental influences, and self-regulation in developing and maintaining regular health-monitoring practices. Self-Efficacy Theory emphasizes individuals' confidence in their ability to correctly perform blood pressure measurement, interpret readings appropriately, maintain monitoring routines, and take recommended actions. Collectively, these theoretical perspectives provide a suitable framework for explaining how community blood pressure self-monitoring education may influence blood pressure monitoring practices among adults in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise adults aged 18 years and above residing in selected urban, semi-urban, and rural communities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, households, and eligible adults. Community blood pressure self-monitoring education will be assessed using indicators such as exposure to self-monitoring education sessions, frequency and duration of education, knowledge of hypertension, awareness of blood pressure measurement procedures, knowledge of appropriate measurement conditions, understanding of correct cuff positioning, knowledge of appropriate body positioning, awareness of factors that may temporarily affect readings, knowledge of blood pressure recording, understanding of repeated measurements, knowledge of appropriate interpretation of readings, awareness of when to seek healthcare, and knowledge of proper device storage and maintenance. Blood pressure monitoring practices will be assessed using indicators such as frequency of blood pressure measurement, consistency of monitoring, use of an appropriate and validated blood pressure device where available, correct sitting position, appropriate cuff placement, adequate rest before measurement, taking repeated readings when appropriate, recording readings accurately, maintaining a blood pressure monitoring log, sharing relevant readings with healthcare providers, and seeking appropriate medical evaluation when elevated readings are identified. Data will be collected using structured questionnaires, blood pressure self-monitoring knowledge assessment tools, observation checklists for measurement technique, blood pressure monitoring records or logs, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Descriptive statistics will be used to summarize participants' demographic characteristics, hypertension history, access to blood pressure devices, sources of health information, exposure to education, and monitoring practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the effect of community blood pressure self-monitoring education on blood pressure monitoring practices. Where a quasi-experimental design is adopted, monitoring practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community blood pressure self-monitoring education has a significant positive effect on blood pressure monitoring practices among adults in Nigeria. Adults exposed to structured and practical self-monitoring education are expected to demonstrate improved knowledge and more consistent blood pressure monitoring practices than adults without comparable exposure. Education may improve participants' ability to prepare appropriately for measurement, position themselves correctly, use blood pressure devices properly, obtain more reliable readings, record measurements, recognize potentially concerning readings, and seek appropriate professional care. Practical demonstrations and supervised measurement exercises may further improve participants' confidence and competence in self-monitoring. However, limited access to validated devices, device cost, low health literacy, misconceptions about hypertension, inconsistent healthcare access, poor follow-up, and difficulty maintaining regular monitoring routines may reduce the effectiveness of education alone. The study therefore expects accessible, practical, culturally appropriate, and continuous community blood pressure self-monitoring education, supported by access to reliable devices and appropriate healthcare services, to contribute significantly to improved blood pressure monitoring practices among adults in Nigeria. The study is expected to contribute to the literature on hypertension prevention, blood pressure self-monitoring, cardiovascular disease prevention, community health education, self-care practices, health promotion, primary healthcare, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, primary healthcare centres, hospitals, healthcare professionals, community health workers, public health practitioners, cardiovascular health organizations, development partners, and policymakers regarding strategies for strengthening hypertension prevention and control. The study will also provide evidence-based recommendations for integrating blood pressure self-monitoring education into community and primary healthcare programmes, improving access to appropriate blood pressure monitoring devices, strengthening community health education, promoting accurate self-measurement techniques, improving referral and follow-up systems, and increasing public awareness of regular blood pressure monitoring across Nigeria.
