Effectiveness of android-based educational media on knowledge, dietary intake and hemoglobin levels for prevention of anemia in adolescent females

Compared to other media, such as print, audiovisual, and social media, educational media based on Android applications must be generated more broadly to prevent anaemia in adolescent females. This study compares the effects of e-posters and LADIES, an android-based educational media intervention, on female adolescents’ knowledge, dietary intake, and haemoglobin levels. This study was conducted using the quasi-experimental method from July to October 2022. This research utilised a pre-test-post-test and a control group design. This study’s sample comprised 49 adolescent females between the ages of 16 and 17, divided into two groups. The intervention group (n = 25) used the LADIES application media; on the other hand, the control group (n = 24) utilised the e-poster media. Results showed the average score of the knowledge (55.60 vs 91.80), nutritional intake (protein (49.41gr vs 54.38 gr), iron (6.42 mg vs 11.50 mg), and vitamin C (12.17mg vs 35.75mg)), and haemoglobin levels (12.34 mg/dl vs 13.21 mg/dl) in the LADIES group before and after the intervention and the average score of the knowledge (52.92 vs 86.46), nutritional intake (protein (50.29 gr vs 67.81 gr), iron (5.88 mg vs 8.96 mg) and vitamin C (11.49 mg vs 33.09 mg)), and haemoglobin levels (12.41 mg/dl vs 12.95 mg/dl) in the e-poster group before and after the intervention. The findings indicated that there were differences between groups in knowledge and nutritional intake (protein and iron) (p<0.01). However, there was no difference between groups in vitamin C intake (p=0.841) or hemoglobin levels (p=0.928). Education using Android-based media (LADIES) is more effective than e-poster media in enhancing female adolescents’ knowledge, nutrient intake, and haemoglobin levels.
