The Utilization of Rosella (Hibiscus Sabdariffa Linn.) Calyx Extract to Increase Hemoglobin and Hematocrit of Female Adolescents Anemia

Abstract

This research aims to prove the provision benefits of Rosella (Hibiscus sabdariffa Linn.) calyx extract to increase hemoglobin and hematocrit levels in female adolescents anemia. This research is a true experiment with a randomized pre-test and post-test control group design. Totals of samples were 40 female adolescents with anemia according to the inclusion and exclusion criteria divided by randomization sampling technique, consisting of two groups intervention groups and control groups. Data analysis used paired t-test statistical test to determine the difference between pretest and post-test each group and an independent t-test to determine the difference between the different groups. The average difference in hemoglobin and hematocrit levels in the intervention group was higher than in the control group. The average difference in hemoglobin levels in the intervention group was 1.8 g/dL in and the control group was 0.9 g/dL, (p < 0.05), The difference in the average hematocrit level in the intervention group was 5.6% and the control group was 2.7% (p < 0.05). The researchers also found significant statistics differences between hemoglobin and hematocrit levels of female adolescents from intervention and control groups s with a p-value < 0.05. The combination of Rosella (Hibiscus sabdariffa Linn.) calyx extract and Fe2+ tablet was effective to increasing hemoglobin and hematocrit levels in female adolescents with anemia.
