Effect of Community Health Education on Preventive Health Practices among Adults in Nigeria

Abstract

Preventive health practices are essential for reducing the burden of communicable and non-communicable diseases and improving population health in Nigeria. However, many adults may not consistently engage in recommended preventive behaviours such as regular health screening, immunization, appropriate hygiene, healthy dietary practices, physical activity, safe water use, sanitation, malaria prevention, and timely healthcare-seeking. Community health education provides an important public health strategy for increasing knowledge, correcting misconceptions, promoting healthy behaviours, and encouraging individuals and households to adopt appropriate preventive health practices. Community-based education may be particularly important in underserved populations where access to formal health information and preventive healthcare services is limited. However, low health literacy, cultural beliefs, socioeconomic constraints, limited community health personnel, inadequate educational resources, and poor access to preventive services may affect the effectiveness of community health education programmes in Nigeria. Against this background, this study investigates the effect of community health education on preventive health practices among adults in Nigeria. The study will be anchored on the Health Belief Model, Social Ecological Model, and Theory of Planned Behavior. The Health Belief Model explains how adults' perceptions of disease susceptibility, perceived severity, perceived benefits of preventive practices, perceived barriers, and cues to action may influence their adoption of preventive health behaviours. The Social Ecological Model emphasizes the influence of individual, household, community, environmental, socioeconomic, and healthcare factors on health behaviour. The Theory of Planned Behavior explains how attitudes, subjective norms, perceived behavioural control, and behavioural intentions may influence adults' decisions to adopt preventive health practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how community health education may influence preventive health practices among adults in Nigeria. The study will adopt a quantitative analytical cross-sectional or quasi-experimental research design. The study population will comprise adults aged 18 years and above residing in selected Nigerian communities. A multistage sampling technique will be used to select states, local government areas, communities, households, and eligible adult participants. Community health education will be assessed using indicators such as exposure to community health education sessions, frequency and duration of education, educational content, health communication methods, involvement of community health workers, use of educational materials, health demonstrations, and follow-up activities. Preventive health practices will be assessed using indicators such as participation in recommended health screening, immunization uptake where applicable, handwashing and personal hygiene, safe water practices, sanitation, malaria prevention, healthy dietary practices, physical activity, avoidance of tobacco and harmful substance use, and timely utilization of preventive healthcare services. Data will be collected using structured questionnaires, community health programme records, health education registers, and relevant public health programme documents. Descriptive statistics will be used to summarize participants' characteristics, exposure to community health education, health knowledge, and preventive 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 health education on preventive health practices. Where a quasi-experimental design is adopted, preventive health practice scores before and after exposure to structured community health education may be compared, while relevant demographic, socioeconomic, and community factors are appropriately controlled. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community health education has a significant positive effect on preventive health practices among adults in Nigeria. Adults who receive regular and comprehensive community health education are expected to demonstrate greater adoption of recommended preventive behaviours than adults with limited exposure to health education. Community health education may improve knowledge of disease prevention, increase awareness of available health services, correct misconceptions, strengthen perceived benefits of preventive practices, and encourage timely healthcare-seeking. However, the translation of knowledge into practice may be influenced by household income, food and water availability, healthcare accessibility, cultural beliefs, community norms, educational level, and availability and affordability of preventive health services. The study therefore expects accessible, culturally appropriate, continuous, and community-specific health education, supported by adequate preventive healthcare services, to contribute significantly to improved preventive health practices among adults in Nigeria. The study is expected to contribute to the literature on community health education, preventive health practices, health promotion, disease prevention, health literacy, community health services, healthcare utilization, 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, local government health authorities, primary healthcare centres, community health workers, public health practitioners, development partners, and policymakers regarding strategies for strengthening community-based health promotion. The study will also provide evidence-based recommendations for expanding community health education programmes, strengthening community health worker capacity, developing culturally appropriate health education materials, improving health literacy, increasing community participation in preventive healthcare, linking health education with accessible preventive services, and integrating community health education into broader primary healthcare and public health programmes across Nigeria.
