Effect of Community Nutrition Education on Healthy Eating Practices among Low-Income Households in Nigeria

Abstract

Healthy nutrition is an important determinant of health and well-being, while inadequate dietary practices may contribute to undernutrition, overweight and obesity, micronutrient deficiencies, and diet-related non-communicable diseases. Low-income households in Nigeria may face particular challenges in adopting healthy eating practices because of food prices, limited household income, inadequate access to diverse foods, food insecurity, limited nutrition knowledge, and reliance on inexpensive energy-dense foods. Community nutrition education provides an opportunity to improve household knowledge of balanced diets, portion sizes, food selection, meal planning, food preparation, and affordable healthy alternatives. Community-based education may also provide practical strategies that are adapted to local food availability and household economic circumstances. Against this background, this study investigates the effect of community nutrition education on healthy eating practices among low-income households 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 household members' perceptions of nutrition-related health risks, perceived severity of diet-related diseases, perceived benefits of healthy eating, perceived barriers, and cues to action may influence dietary practices. Social Cognitive Theory emphasizes observational learning, self-efficacy, behavioural reinforcement, and environmental influences in the adoption and maintenance of healthy eating behaviours. The Social Ecological Model emphasizes the interaction between individual, household, community, food-environment, and socioeconomic factors in shaping dietary practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how community nutrition education may influence healthy eating practices among low-income households in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise adults responsible for food purchasing or meal preparation in selected low-income households across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, households, and eligible participants. Community nutrition education will be assessed using indicators such as exposure to structured nutrition education, frequency and duration of educational sessions, information on balanced diets, food groups, portion sizes, meal planning, food budgeting, healthy food preparation, reduction of excess salt, sugar and unhealthy fats, consumption of fruits and vegetables, dietary diversity, and locally available affordable nutritious foods. Healthy eating practices will be assessed using indicators such as dietary diversity, frequency of fruit and vegetable consumption, consumption of whole or minimally processed foods, appropriate portion sizes, reduced intake of sugary drinks and highly processed foods, healthy cooking methods, meal planning, appropriate food purchasing, and household adherence to recommended dietary practices. Data will be collected using structured questionnaires, validated nutrition knowledge and dietary practice instruments, household dietary assessments, food-frequency questionnaires, 24-hour dietary recalls where appropriate, and community nutrition programme records. Descriptive statistics will be used to summarize participants' characteristics, exposure to community nutrition education, and healthy eating 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 nutrition education on healthy eating practices. Where a quasi-experimental design is adopted, healthy eating practice scores before and after the educational intervention may be compared to determine changes associated with the programme. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community nutrition education has a significant positive effect on healthy eating practices among low-income households in Nigeria. Households exposed to structured and practical nutrition education are expected to demonstrate improved dietary diversity, increased consumption of fruits and vegetables where affordable and available, better meal planning, healthier food preparation methods, and reduced consumption of foods high in excess salt, sugar, and unhealthy fats. Practical demonstrations, budgeting guidance, community cooking sessions, and education on locally available nutritious foods may improve households' ability to apply nutrition information within their financial limitations. Education may also increase awareness that healthy diets can be achieved through appropriate combinations of locally available foods rather than relying exclusively on expensive food products. However, food insecurity, rising food prices, unemployment, limited access to diverse foods, household size, cultural food preferences, and inadequate food markets may limit the adoption of recommended practices. The study therefore expects accessible, practical, culturally appropriate, and economically sensitive community nutrition education to contribute significantly to improved healthy eating practices among low-income households in Nigeria. The study is expected to contribute to the literature on community nutrition education, healthy eating practices, low-income households, dietary diversity, food insecurity, nutrition education, community health, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Agriculture and Food Security, National Primary Health Care Development Agency, state ministries of health, local government health authorities, nutrition programmes, community health workers, non-governmental organizations, development partners, and policymakers regarding strategies for improving dietary practices among economically vulnerable households. The study will also provide evidence-based recommendations for expanding community-based nutrition education, promoting affordable locally available nutritious foods, integrating nutrition counselling into primary healthcare services, strengthening household food-budgeting education, addressing barriers to dietary diversity, and developing sustainable community nutrition programmes for low-income households across Nigeria.
