The Effectiveness of Iron-folic Acid Supplementation and Education Intervention to Hemoglobin Level, Knowledge, and Compliance among Adolescent Girls in Islamic Boarding School

Abstract

Abstract BACKGROUND: Adolescent girls are at a high risk of iron deficiency anemia. Weekly iron-folic acid supplementation (WIFAS) is recommended to address anemia, but it is still ineffective to reduce the prevalence of anemia in Indonesia. Lack of knowledge and low adherence are the factors associated with the problem. AIM: The study aimed to assess the effectiveness of education-combined WIFAS intervention compared to WIFAS intervention, and to identify the compliance of iron-folic acid tablets intake. METHODS: A quasi-experimental study was carried out on November 2020 to March 2021. By simple random sampling, a total of 135 adolescent girls in islamic boarding schools in Semarang, Indonesia were divided into two groups: WIFAS group only received WIFAS and the WIFAS+Education group received combination of WIFAS and education intervention for 16 weeks. Hemoglobin level was measured by Cyanmethemoglobin method. The knowledge and compliance were determined through the questionnaires. Mann-Whitney, Wilcoxon, and McNemar tests were performed to analyze the effect of intervention by SPSS 22 software. RESULTS: Mean of Hb levels and knowledge scores before and after intervention in the WIFAS group were 13.38 g/dL and 13.08 g/dL (p=0.055); and 79.08 and 76.21 (p=0.93), respectively, meanwhile in the WIFAS+Education group were 12.79 g/dL and 12.69 g/dL (p=0.248); and 78.67 and 82.10 (p=0.008), respectively. The increases of anemia prevalence both in the WIFAS group and the WIFAS+Education group was not statistically significant. There was no significant difference of the compliance both groups (p=0.095). CONCLUSION: Education intervention was effective to increase the knowledge regarding anemia and nutrition. The education intervention to trustees of islamic boarding school is needed to increase the compliance of WIFAS, so it can improve the effectiveness of WIFAS among adolescent girls.
