<![CDATA[The incidence of anemia in adolescent girls is still high at 32%. Teenage girls with anemia during the pregnancy period can result in the risk of infant and maternal mortality, as well as low birth weight babies. The study aims to determine the relationship between knowledge and menstrual cycles with the incidence of anemia in adolescent girls at SMKN X Sumedang. The type of study is correlational. The population is all female students who have anemia. The number of samples is 67 female students. Inclusion criteria include adolescent girls with anemia (Hb levels <12 g/dL), not on a diet, not menstruating, and grade X. The sampling technique is simple random sampling. The instrument uses a checklist, observation sheet, and Hb examination (quick check). Data analysis uses the Spearman rank test. The results of the study did not show a relationship between the level of knowledge and menstrual cycles with the incidence of anemia (p >0.05). Evidenced by the level of expertise of respondents included in the good category and experienced mild anemia (19.4%), moderate (32.8%), and severe (3%). Meanwhile, respondents with a low level of knowledge have experienced mild to moderate anemia (22.4%). Meanwhile, adolescent girls experienced normal menstrual cycles and mild anemia (31.3%), moderate (50.7%), and severe (1.5%). Meanwhile, respondents experienced irregular menstrual cycles and mild anemia (10.5%), moderate (4.5%), and severe (1.5%). Future researchers can investigate other factors that cause anemia.]]>
