Effect of Pneumococcal Disease Education on Pneumococcal Disease Prevention Practices among Parents in Nigeria

Abstract

Pneumococcal disease remains an important public health concern in Nigeria and may cause serious illnesses such as pneumonia, meningitis, bloodstream infections, and other invasive infections, particularly among young children and other vulnerable populations. Parents play an important role in preventing pneumococcal disease through appropriate childhood vaccination, recognition of warning signs, hygiene practices, reduction of exposure to respiratory infections, and timely healthcare-seeking. However, inadequate knowledge of pneumococcal disease, misconceptions about vaccination, low awareness of risk factors, financial barriers, and limited access to healthcare services may affect parents' adoption of appropriate preventive practices. Pneumococcal disease education provides an opportunity to improve parental knowledge of disease transmission, symptoms, risk factors, vaccination, and other preventive measures. Against this background, this study investigates the effect of pneumococcal disease education on pneumococcal disease prevention practices among parents in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and Social Ecological Model. The Health Belief Model explains how parents' perceptions of their children's susceptibility to pneumococcal disease, perceived severity, perceived benefits of preventive practices, perceived barriers, and cues to action may influence adoption of disease-prevention behaviours. Social Cognitive Theory emphasizes learning through observation, practical demonstration, reinforcement, feedback, and self-efficacy in developing and maintaining appropriate health practices. The Social Ecological Model emphasizes the influence of individual, family, community, healthcare, and environmental factors on childhood disease prevention. Collectively, these theoretical perspectives provide a suitable framework for explaining how pneumococcal disease education may influence disease-prevention practices among parents in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise parents or primary caregivers of children, particularly those with children within the applicable pneumococcal vaccination age range, 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, healthcare facilities, and eligible parents. Pneumococcal disease education will be assessed using indicators such as frequency and duration of education sessions, information on pneumococcal disease transmission, symptoms and complications, risk factors, pneumococcal vaccination, vaccine safety and benefits, respiratory hygiene, hand hygiene, prevention of exposure to respiratory infections, early recognition of danger signs, appropriate healthcare-seeking, availability of educational materials, practical demonstrations, and follow-up education. Pneumococcal disease prevention practices will be assessed using indicators such as adherence to recommended pneumococcal vaccination schedules, maintenance of hand hygiene, respiratory hygiene, reduction of children's exposure to respiratory infections, appropriate household hygiene, avoidance of tobacco smoke exposure, recognition of warning signs, timely healthcare-seeking, and compliance with healthcare providers' preventive recommendations. Data will be collected using structured questionnaires, standardized parental knowledge and practice assessment tools, child immunization cards or vaccination records where available, healthcare-facility records, and relevant community health programme documents. Descriptive statistics will be used to summarize parents' characteristics, knowledge of pneumococcal disease, exposure to education, vaccination status, and prevention 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 pneumococcal disease education on disease-prevention practices. Where a quasi-experimental design is adopted, prevention-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 pneumococcal disease education has a significant positive effect on pneumococcal disease prevention practices among parents in Nigeria. Parents exposed to structured and practical pneumococcal disease education are expected to demonstrate better adoption of recommended preventive practices than parents without comparable exposure. Education may improve parents' understanding of pneumococcal disease, its transmission, symptoms, complications, and prevention, while increasing awareness of the importance of recommended pneumococcal vaccination. Education may also encourage appropriate hand and respiratory hygiene, reduction of children's exposure to tobacco smoke and respiratory infections, recognition of danger signs, and timely healthcare-seeking. Practical education may help parents identify situations requiring prompt medical attention and improve confidence in following vaccination and preventive-care recommendations. However, vaccine misinformation, limited access to vaccination services, financial barriers, transportation difficulties, vaccine availability, low health literacy, and inadequate access to healthcare may reduce the effectiveness of education alone. The study therefore expects accessible, culturally appropriate, evidence-based, and continuous pneumococcal disease education, supported by reliable vaccination and primary healthcare services, to contribute significantly to improved pneumococcal disease prevention practices among parents in Nigeria. The study is expected to contribute to the literature on pneumococcal disease prevention, childhood respiratory infections, parental health education, pneumococcal vaccination, infectious disease prevention, child health, immunization, community health, 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, Nigeria Centre for Disease Control and Prevention, state ministries of health, local government health authorities, primary healthcare centres, community health workers, maternal and child health programmes, development partners, and policymakers regarding strategies for strengthening pneumococcal disease prevention. The study will also provide evidence-based recommendations for integrating pneumococcal disease education into routine child-health and immunization services, improving parental awareness of pneumococcal vaccination, addressing vaccine misinformation, strengthening community health education, improving access to vaccination services, and promoting early recognition and appropriate management of pneumococcal disease across Nigeria.
