Impact of Salt-Reduction Education on Dietary Salt-Reduction Practices among Adults in Nigeria

Abstract

Excessive dietary salt consumption is an important public health concern because high sodium intake is associated with elevated blood pressure and increased risk of cardiovascular disease, stroke, and other non-communicable diseases. Adults in Nigeria may consume excessive amounts of salt through discretionary salt use, salty seasonings, processed foods, instant noodles, snacks, preserved foods, and meals prepared outside the home. Limited awareness of the health consequences of excessive salt intake, difficulty identifying high-sodium foods, cultural dietary practices, and preference for salty foods may make salt reduction challenging. Salt-reduction education provides an opportunity to improve adults' knowledge of dietary sodium, identify sources of excessive salt, and promote practical strategies for reducing salt intake. Against this background, this study investigates the impact of salt-reduction education on dietary salt-reduction practices among adults in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and Theory of Planned Behavior. The Health Belief Model explains how adults' perceptions of susceptibility to hypertension and cardiovascular disease, perceived severity, perceived benefits of reducing salt intake, perceived barriers, and cues to action may influence dietary practices. Social Cognitive Theory emphasizes observational learning, behavioural modelling, self-efficacy, reinforcement, and environmental influences in developing and maintaining healthier dietary behaviours. The Theory of Planned Behavior explains how attitudes toward salt reduction, perceived social expectations, and perceived behavioural control may influence adults' intentions and actual dietary practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how salt-reduction education may influence dietary salt-reduction 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. Salt-reduction education will be assessed using indicators such as exposure to dietary salt education sessions, frequency and duration of education, knowledge of recommended salt intake, awareness of the relationship between salt and blood pressure, ability to identify high-sodium foods, knowledge of discretionary salt sources, awareness of sodium content on food labels, knowledge of healthier seasoning alternatives, and understanding of practical strategies for reducing salt consumption. Dietary salt-reduction practices will be assessed using indicators such as reducing salt added during cooking, avoiding adding salt at the table, reducing the use of salty seasonings, limiting processed and packaged foods high in sodium, reading food labels for sodium content, reducing consumption of salty snacks and preserved foods, using herbs and spices as alternatives to salt, requesting less salt when eating outside the home, and maintaining consistent salt-reduction practices. Data will be collected using structured questionnaires, dietary practice assessment tools, food-frequency questionnaires, nutrition knowledge instruments, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Where feasible, dietary sodium intake may also be assessed using appropriate dietary assessment methods or other suitable measures. Descriptive statistics will be used to summarize participants' demographic characteristics, dietary patterns, exposure to salt-reduction education, and salt-reduction 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 impact of salt-reduction education on dietary salt-reduction practices. Where a quasi-experimental design is adopted, dietary 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 salt-reduction education has a significant positive impact on dietary salt-reduction practices among adults in Nigeria. Adults exposed to structured and practical salt-reduction education are expected to demonstrate improved knowledge of sodium-related health risks and greater adoption of salt-reduction practices than adults without comparable exposure. Education may improve participants' ability to identify major dietary sources of sodium, interpret food labels, reduce discretionary salt use, choose lower-sodium foods, and adopt healthier alternatives for flavouring meals. Practical demonstrations, cooking education, household involvement, and community-based nutrition activities may further strengthen participants' ability to maintain reduced-salt dietary practices. However, cultural food preferences, widespread use of salty seasonings, affordability and availability of lower-sodium alternatives, consumption of processed foods, eating outside the home, and perceptions that low-salt meals are less enjoyable may limit the effectiveness of education alone. The study therefore expects continuous, practical, culturally appropriate, and accessible salt-reduction education, supported by healthier food environments and improved availability of lower-sodium food choices, to contribute significantly to improved dietary salt-reduction practices among adults in Nigeria. The study is expected to contribute to the literature on dietary salt reduction, hypertension prevention, cardiovascular disease prevention, nutrition education, healthy dietary practices, non-communicable disease prevention, health promotion, community nutrition, 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, nutritionists, dietitians, community health workers, public health practitioners, healthcare professionals, food manufacturers, development partners, and policymakers regarding strategies for reducing excessive salt consumption. The study will also provide evidence-based recommendations for strengthening community salt-reduction education, improving public awareness of sodium-related health risks, promoting food-label reading, encouraging healthier cooking practices, improving access to lower-sodium food alternatives, integrating salt-reduction counselling into primary healthcare services, and developing sustainable dietary salt-reduction programmes across Nigeria.
