FACE-APPS-Based Approach for Improving Iron Deficiency Anaemia Indicators Among Female Adolescents at Marginalized Communities

Anemia remains a major global public health concern. It disproportionately affects vulnerable populations, particularly adolescent females. According to the World Health Organization (WHO), anemia affects a substantial proportion of the global population. Adolescent girls represent a high-risk group due to rapid growth, increased nutritional requirements, and the onset of menstruation. Globally, approximately 15% of adolescents are affected by anemia. Prevalence varies widely across regions, from less than 10% in high-income countries to over 40% in low- and middle-income settings.

Anemia during adolescence has significant consequences. Iron deficiency anemia (IDA) impairs cognitive development, academic performance, and physical capacity. It also increases the risk of infection and affects psychosocial health. For adolescent girls, untreated anemia raises long-term risks-especially in future pregnancies, such as maternal mortality, low birth weight, and adverse neonatal outcomes. Thus, anemia is both an immediate and intergenerational public health issue.

Research is especially needed in KSA, where anemia is a major public health concern for children, adolescents, and women. Studies report high rates of anemia among adolescent females, with estimates ranging from 35% to over 50% in some regions . Despite ongoing efforts, disparities endure, particularly in underserved communities with limited access to healthcare and nutrition.

Given these gaps, the present study seeks to evaluate the impact of a blended digital health literacy intervention on behavioral and biological indicators of IDA among female adolescents in marginalized communities. Through the integration of school-based delivery, collaboration with primary health care, and culturally tailored digital education, this research intends to generate robust evidence to inform scalable and sustainable anemia prevention strategies. The study addresses a critical gap in the literature by assessing the effectiveness of a comprehensive, theory-driven intervention in an under-researched, high-need population.

Inclusion criteria

• Adolescent females aged 14-17 years
• who are attending high school
• who have haemoglobin levels <12 mg/dl and serum ferritin levels below 15 μg/L

Exclusion criteria

• Adolescents have other causes of anemia, such as thalassemia and sickle cell anemia, and malaria will be excluded.
• Adolescents with chronic diseases that affect iron metabolism (e.g., chronic kidney disease) or other severe illnesses or conditions that may interfere with active participation.
• Pregnant females will be excluded (if included in the age group).
• Adolescents with gastrointestinal ulcers, colon polyps, or cancers; celiac disease; Crohn's disease; or gastric bypass surgery.
