The relationship between knowledge and compliance to consuming blood added tablets in adolescents' women: A literature review

Introduction: Iron deficiency anemia is a significant public health concern, particularly among adolescent girls, due to their increased iron requirements during periods of rapid growth and menstruation. The World Health Organization (WHO) estimates that over one-third of adolescent girls in developing countries suffer from anemia, which can lead to reduced cognitive and physical performance, weakened immunity, and complications during pregnancy later in life. Knowledge plays a crucial role in shaping health behaviors. Adolescents with a better understanding of anemia and the importance of iron supplements are more likely to adhere to the prescribed regimen. This adherence is essential for ensuring the effectiveness of the intervention in reducing anemia prevalence. Method: This study is a literature review, drawing from sources in Google Scholar, PUBMED, and Science Direct, focusing on research published between 2020 and 2024. The study included only original research articles in English or Indonesian with all the required components. Result and Discussion: From the literature search, 10 studies met the inclusion criteria. Among them, 9 studies found a correlation between knowledge and compliance to consuming blood added tablets, while 1 study found no correlation. Conclusion: According to reviews, knowledge is associated compliance to consuming blood added tablets in adolescents, although some studies have not shown an association.
