Abstract

Menstruation process in adolescents results in loss of iron in the blood of 12.5-15 mg / month, causing a decrease in Hb levels so it is necessary to take additional supplements, namely blood supplementary tablets. The coverage of giving blood supplementary tablets in 2018 was 76.2% but only 1.4% consumed 52 grains per year. So it is necessary to make an effort to increase the knowledge of girl about blood supplementary tablets, namely by providing counseling using leaflets. This study aims to analyze the effect of counseling using leaflets on girl's knowledge of blood supplementary tablets at SMP Swasta Nasional of Langkat Regency in 2021. The type of research was pre-experimental with a one group pretest-posttest design and total sampling, namely 33 students in grade VII. The average knowledge of girl before being given counseling using leaflets was 39.09 with an SD of 5.07, and the average knowledge of girls after being given counseling using leaflets was 75.91 with an SD of 5.51. This means that there is an increase in the average knowledge before and after by 36.82 SD 0.44. The results of the Paired Simples T-test obtained value (0.00) < (0.05), meaning that counseling using leaflets was proven to significantly increase the average knowledge of girl. It is expected that school principals and teachers when providing counseling related to increasing students' knowledge are expected to use leaflets as a medium in providing information.
