Humans lose iron through feces every day, and young women also lose iron through menstruation every month. Conseqently, young women lose 1.3 mg of iron per day, which accelerates the occurrence of anemia, causing problems during pregnancy. This study aimed to investigate the correlation between knowledge, attitude and family support with anemia prevention behavior in young women in Senior High School 1 Bojonegara, Serang in 2021. This research was a descriptive correlation study with a cross-sectional design and it involved 184 respondents selected using a proportional random sampling technique. The data were collected using questionnaires distributed through social media and WhatsApp groups. The results showed that most students had a low level of knowledge (60.9%), a negative attitude (51.6%), a less supportive family (52.7%), and low preventative behavior (55.4%). This study also found no relationship between knowledge (p = 0.463) or attitude (p = 0.521) and anemia prevention behavior. However, there was a relationship between family support and anemia prevention behavior (p < 0.001). Motivation and exposure to information about anemia are necessary to improve anemia prevention behavior.
