Effect of Community-Based Anaemia Screening on Iron-Deficiency Anaemia Detection among Adolescent Girls in Nigeria

Abstract

Iron-deficiency anaemia remains an important public health concern among adolescent girls in Nigeria and may negatively affect physical growth, cognitive development, concentration, educational performance, physical capacity, and overall well-being. Adolescent girls are particularly vulnerable to iron deficiency because of increased nutritional requirements during growth and menstrual blood loss following the onset of menstruation. Poor dietary intake of iron, inadequate dietary diversity, parasitic infections, recurrent illness, and limited access to appropriate nutritional and healthcare services may further increase the risk of iron-deficiency anaemia. The condition may develop gradually and remain undetected when symptoms are mild or attributed to tiredness and other common adolescent experiences. Community-based anaemia screening provides an opportunity to identify adolescent girls with low haemoglobin levels and suspected iron-deficiency anaemia through accessible screening activities conducted within communities, primary healthcare centres, schools, youth health programmes, and community outreach settings. Early detection may facilitate confirmatory assessment, nutritional counselling, appropriate iron supplementation, investigation of underlying causes, and timely management. However, inadequate screening coverage, limited laboratory facilities, shortage of trained healthcare personnel, low awareness, financial constraints, and weak referral and follow-up systems may limit the effectiveness of community-based anaemia screening in Nigeria. Against this background, this study investigates the effect of community-based anaemia screening on iron-deficiency anaemia detection among adolescent girls in Nigeria. The study will be anchored on the Health Belief Model, Social Ecological Model, and the Health Systems Framework. The Health Belief Model explains how adolescent girls' and their caregivers' perceptions of susceptibility to anaemia, perceived severity, perceived benefits of screening, perceived barriers, and cues to action may influence participation in community-based anaemia screening. The Social Ecological Model emphasizes the influence of individual, family, school, community, dietary, socioeconomic, and environmental factors on adolescent nutritional health, anaemia risk, healthcare-seeking behaviour, and access to preventive services. The Health Systems Framework emphasizes service delivery, health workforce, health information, medical products and technologies, financing, and accessibility as essential components of effective community-based anaemia screening and management programmes. Collectively, these theoretical perspectives provide a suitable framework for explaining how community-based anaemia screening may influence iron-deficiency anaemia detection among adolescent girls in Nigeria. The study will adopt a quantitative cross-sectional analytical or quasi-experimental research design. The study population will comprise adolescent girls aged 10 to 19 years residing in selected communities across Nigeria. A multistage sampling technique will be used to select states, local government areas, communities, households, schools, and eligible adolescent girls. Community-based anaemia screening will be measured using indicators such as availability of screening services, screening coverage, frequency of screening activities, haemoglobin testing, assessment of dietary and anaemia-related risk factors, assessment of menstrual history where appropriate, availability of trained healthcare personnel, screening equipment, nutrition education, and referral arrangements. Iron-deficiency anaemia detection will be assessed using indicators such as low haemoglobin levels, laboratory evidence of iron deficiency where appropriate, newly identified iron-deficiency anaemia, severity of anaemia, iron-status indicators such as ferritin where available, referrals for confirmatory assessment, identification of possible underlying causes, and linkage to appropriate nutritional or medical management. Data will be collected using structured questionnaires, community screening registers, haemoglobin and laboratory records, nutritional assessment forms, healthcare facility records, referral registers, and relevant programme documents. Descriptive statistics will be used to summarize participants' characteristics, screening coverage, nutritional and laboratory findings, and patterns of iron-deficiency anaemia detection. Inferential statistical techniques, including chi-square tests, correlation analysis, and logistic or multiple regression analysis, will be used to determine the effect of community-based anaemia screening on iron-deficiency anaemia detection. Where appropriate, iron-deficiency anaemia detection rates before and after implementation of community-based screening activities may be compared 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 community-based anaemia screening has a significant positive effect on iron-deficiency anaemia detection among adolescent girls in Nigeria. Adolescent girls who participate in community-based anaemia screening are expected to have a higher likelihood of having previously undetected anaemia or iron deficiency identified than those without access to such services. Community-based screening may facilitate early identification of low haemoglobin levels and suspected iron deficiency and provide opportunities for appropriate laboratory assessment, nutritional counselling, iron supplementation where indicated, and investigation of underlying causes. Bringing screening services closer to adolescent girls may reduce geographical, financial, and time-related barriers and increase participation in preventive health assessments. Community-based nutrition education may also improve knowledge of iron-rich foods, dietary diversity, menstrual health, anaemia prevention, and appropriate healthcare-seeking behaviour. Early detection and management may help reduce the adverse effects of iron-deficiency anaemia on concentration, physical capacity, school participation, and adolescent development. Conversely, inadequate screening coverage, limited laboratory capacity, shortage of trained personnel, low awareness, financial barriers, poor dietary practices, and weak referral and follow-up systems may reduce the effectiveness of community-based anaemia screening. The study therefore expects accessible and well-organized community-based anaemia screening to contribute significantly to improved detection and early management of iron-deficiency anaemia among adolescent girls in Nigeria. The study is expected to contribute to the literature on community-based anaemia screening, iron-deficiency anaemia detection, adolescent girls' health, nutritional health, adolescent nutrition, menstrual health, school and community health services, preventive healthcare, 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, Federal Ministry of Education, state ministries of health and education, primary healthcare centres, schools, nutrition programmes, healthcare providers, community health workers, development partners, and policymakers regarding strategies for improving adolescent nutritional health. The study will also provide evidence-based recommendations for expanding community-based anaemia screening programmes, improving access to haemoglobin and appropriate iron-status testing, strengthening nutrition and anaemia-prevention education, increasing availability of trained healthcare and laboratory personnel, promoting consumption of iron-rich and diverse diets, improving access to iron supplementation where indicated, strengthening referral and follow-up systems, addressing underlying causes of anaemia, and integrating anaemia screening into comprehensive adolescent health and nutrition programmes across Nigeria.
