Impact of Flood Health Education on Flood-Related Disease Prevention Practices among Flood-Prone Communities in Nigeria

Abstract

Flooding is an important environmental and public health challenge in Nigeria, particularly in communities exposed to seasonal flooding, heavy rainfall, river overflow, and inadequate drainage systems. Flood events can increase the risk of waterborne, foodborne, vector-borne, and other infectious diseases through contamination of drinking-water sources, disruption of sanitation facilities, increased mosquito breeding, unsafe food handling, displacement, overcrowding, and reduced access to healthcare services. Flood health education provides community residents with information about the health risks associated with flooding and practical measures for preventing disease before, during, and after flood events. Flood-related disease prevention practices refer to behaviours adopted by residents to reduce exposure to flood-associated health risks, including safe drinking-water practices, appropriate food hygiene, hand hygiene, proper sanitation, mosquito-bite prevention, safe waste disposal, avoidance of contaminated floodwater, protection of household water sources, and timely healthcare-seeking when illness or suspected exposure occurs. In Nigeria, inadequate flood-related disease prevention practices may be associated with limited awareness of flood-associated health risks, misinformation, inadequate preparedness, poor access to safe water and sanitation, displacement, poverty, and limited availability of emergency health information. Effective flood health education may improve residents' understanding of flood-related disease risks and encourage appropriate preventive practices. Against this background, this study investigates the impact of flood health education on flood-related disease prevention practices among residents of flood-prone communities in Nigeria. The study is anchored on the Health Belief Model, Social Cognitive Theory, and the Knowledge-Attitude-Practice framework. The Health Belief Model provides a framework for understanding residents' adoption of flood-related disease prevention practices through perceived susceptibility to flood-associated diseases, perceived severity of possible health consequences, perceived benefits of preventive measures, perceived barriers, and cues to action. Social Cognitive Theory emphasizes the interaction between knowledge, self-efficacy, community influences, observational learning, environmental conditions, and preventive health behaviour. The Knowledge-Attitude-Practice framework provides a basis for examining how flood health education may improve knowledge and attitudes and translate these improvements into appropriate disease prevention practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how flood health education may influence flood-related disease prevention practices among residents of flood-prone communities in Nigeria. The study will adopt a quantitative quasi-experimental research design. Primary data will be collected from residents of selected flood-prone communities in Nigeria using a structured interviewer-administered questionnaire, flood-health knowledge assessment, and standardized flood-related disease prevention practice checklist. A multistage sampling technique will be employed to select states, local government areas, flood-prone communities, households, and eligible adult residents. Where feasible, selected communities will be assigned to intervention and comparison groups. Residents in the intervention communities will receive structured flood health education through community meetings, household sensitization, demonstrations, visual materials, and participatory health-education sessions. The education will cover flood-related health risks, safe drinking-water practices, water purification and storage, food hygiene, handwashing, sanitation, mosquito-bite prevention, safe waste disposal, avoidance of contaminated floodwater, protection of household water sources, recognition of common flood-related illnesses, emergency preparedness, and appropriate healthcare-seeking. Flood-related disease prevention practices will be assessed using indicators such as use of safe drinking water, appropriate water treatment and storage, hand hygiene, safe food handling, mosquito-control practices, sanitation practices, waste disposal, avoidance of unnecessary contact with contaminated floodwater, protection of household water sources, and timely utilization of healthcare services when illness occurs. Where feasible, household and environmental observations will complement self-reported practices. Descriptive statistics will be used to summarize residents' sociodemographic characteristics, previous flood experience, exposure to health education, flood-health knowledge, and prevention practice scores. Inferential statistical techniques, including chi-square tests, paired-sample tests, independent-sample tests, and multiple regression analysis, will be used to determine the impact of flood health education on flood-related disease prevention practices. Where appropriate, prevention practices before and after the intervention will be compared. Diagnostic tests will also be conducted to assess the reliability of the research instruments, model assumptions, goodness of fit, and robustness of the findings. The study is expected to find that flood health education has a significant positive impact on flood-related disease prevention practices among residents of flood-prone communities in Nigeria. Residents exposed to structured flood health education are expected to demonstrate improved knowledge of flood-associated disease risks and greater adoption of appropriate preventive behaviours. Education is expected to improve safe drinking-water practices, water treatment and storage, food hygiene, handwashing, sanitation, mosquito-bite prevention, waste disposal, avoidance of contaminated floodwater, and timely healthcare-seeking. Practical, community-based education delivered before and during periods of increased flood risk is expected to be particularly effective in improving preparedness and preventive behaviour. However, education alone may not guarantee sustained prevention practices because residents may continue to face structural challenges such as displacement, destruction of sanitation facilities, limited access to clean water, inadequate drainage, overcrowding, poverty, poor waste-management systems, and restricted access to healthcare during flood events. Consequently, flood health education may be most effective when combined with improved emergency preparedness, access to safe water and sanitation, mosquito-control measures, effective waste management, early-warning systems, accessible healthcare services, and coordinated community disaster-response programmes. The study is expected to contribute to the literature on flood health education, flood-related disease prevention, environmental health, disaster health, community health, health education, emergency preparedness, climate-related health risks, and public health in Nigeria by providing empirical evidence on the impact of flood health education on disease prevention practices among residents of flood-prone communities. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Emergency Management Agency, state emergency management agencies, state ministries of health and environment, local government authorities, WASH programmes, public health practitioners, environmental health officers, community health workers, health educators, development partners, and policymakers regarding strategies for reducing flood-related health risks. The study will also provide evidence-based recommendations for strengthening community flood-health education, integrating health preparedness into disaster-management programmes, improving access to safe water and sanitation during floods, strengthening disease surveillance and early-warning systems, expanding community-based emergency health interventions, and promoting sustainable flood-related disease prevention practices in flood-prone communities in Nigeria.
