World Health Organization (WHO) lists of anemia as one of the top ten health problems faced by modern Women with reproductive age (WUS), pregnant women, children of school age, and adolescents are at higher risk of anemia (Simanullang, 2. According to WHO 2011, the cut-off reference in children aged 6 - 59 months is < 11 g/dL, for children aged 5 - 11 years is < 11. 5 g/dL, for children aged 12 - 14 years is < 12 g/dL, women of childbearing age Ou 15 years is < 12 g/dL, pregnant women is < 11 g/dL, and men aged Ou 15 years is < 13 g/dL (Kementrian Kesehatan Republik Indonesia, 2. The prevalence of anemia among adolescents in Indonesia reaches 32%. The proportion of anemia is greater in women . 2%) compared to men . 3%) (Kementrian Kesehatan Republik Indonesia, 2. The pevalence of anemia in Bali Province in 2019 was 07% (Bali Provincial Health Office, 2. to 78 percent in 2020. Anemia in Denpasar was increased by 4. 7% to 7. 55% in 2020. Anemia can cause fatigue, reduced ability to concentrate while learning, thus reducing the quality of learning and reducing productivity.

The prevalence of anemia in adolescents that is not addressed properly will continue into adulthood and become a major contributor to maternal mortality, prematurity and low birth weight Many factors cause anemia, including internal and external factors. Internal factors that contribute to the emergence of anemia are chronic blood loss, namely menstruation (Yuwono, 2. According to research conducted by Kumalasari in 2018, it was stated that there was a relationship between the menstrual pattern and the prevalence of anemia in teenage girls who were students of junior high school Negeri Lampung east in 2018. The research results from Sriningrat, show that the prevalence of anemia in adolescent girls in of Denpasar were 45. The incidence of anemia in adolescent girls in the city of Denpasar tends to occur in adolescent girls with low energy, low protein, low iron and low vitamin C intake, malnutrition, menstrual cycle, long duration, high activity and low income of the person (Sriningrat et al. , 2.

DISSCUSSION Anemia is a condition where hemoglobin (H. in the blood is lower than the normal value for a group of people according to age and Abnormal 25,00 75,00 0,00 100,00 50,00 50,00 100,00 75,00 25,00 Normal 19,23 46,15 34,62 100,00 50,00 50,00 76,92 23,08 Based on the results of data analysis that has been done, 22 . 33%) have hemoglobin levels Ou 12 g/dL which means they are not anemic and 8 . 67%) students have hemoglobin levels < 12 g/dL which means they are anemic. This 26. 67% figure is greater than the anemia rate in Bali Province in 2020 which is This figure of 26. 67% is also greater than the anemia rate in Denpasar City in 2020, which This can occur because SMP Negeri 14 Denpasar has not carried out the government program, namely in providing blood supplement This 26. 67% figure is lower than research conducted by Sriningrat involving 74 female students in junior and senior high schools in Denpasar City (Sriningrat et al. , 2. The study showed the results that 34 . 9%) female students suffer of anemia. This is also in line with research conducted by Widyanthini, involving 135 students at SMK X in Bangli Regency which showed that 92. 6% of students did not suffered of anemia (Widyanthini & Widyanthari, 2. Adel Viona, et all : Description of Menstrual Pattern Based on Anemia Status in Public Junior High School Students 14 Denpasar INTERNASIONAL CONFERENCE ON MULTIDISCIPLINARY APPROACHES IN HEALTH SCIENCE VOLUME 1 TAHUN 2023. ISSN 3032-4408 (Onlin. https://ejournal. poltekkes-denpasar. id/index. php/icmahs This is because Bangli district has been active in implementing the government program, namely the provision of blood supplement tablets. This is also in line with research conducted by Mirani involving 86 adolescent girls in Langsa City which showed that 57 . 3%) did not suffered of anemia (Mirani et al. , 2. Iron deficiency anemia is anemia caused by a lack of the mineral fe or iron. This deficiency can be caused by a lack of consumption of ironcontaining foods, impaired absorption or excretion of iron from the body such as when adolescent girls experience bleeding. The factors that influence the occurrence of anemia are post-menstrual blood loss, nutritional status, food intake and socioeconomics. with poor nutritional status are at risk of 1. times more anemia than adolescents who have normal nutritional status (Mirani et al. , 2. According of menstrual patterns, female students who experienced a short menstrual cycle were 6 people . %) and female students who experienced a long menstrual cycle were 9 people . %). Students who experience abnormal menstrual duration are 15 people . %) and students who experience abnormal menstrual volume are 23 people . %). This is in line with research conducted by Sholicha, involving 62 samples at SMA Negeri 1 Gresik, which showed that 70% of the samples experienced abnormal menstruation. After experienced short menstrual cycles (< 21 day. and long menstrual cycles (> 35 day. , experienced menstruation for < 4 days and > 7 days, experienced pain during menstruation, and experienced menstruation more than once a month (Sholicha & Muniroh, 2. This is also in Herlinadiyaningsih, involving 147 female students at SMA Negeri 4 Palangka Raya which showed the results that 69 . 9%) female students experienced a short menstrual cycle (<21 day. , 24 . 3%) female students experienced a long menstrual cycle (>35 day. (Gultom et al. , 2. Girls who experienced abnormal menstrual volume with anemia were 7 people . 50%) and girls who experienced normal menstrual volume with anemia were 1 person . 50%). This is in line with research conducted by Sholichai, involving 62 students in grades X and XI at SMA Negeri 1 Gresik, which showed the results of 70% of students experiencing anemia and abnormal menstrual Adolescent girls who experience abnormal menstruation tend to be more at risk of anemia Anemia of adolescent girls can occur because adolescent girls experience menstruation which causes heavy blood loss during abnormal menstruation (Sholicha & Muniroh, 2. This is also in line with research conducted by Nofianti, involving 89 students at SMP Negeri 2 Kerambitan which resulted in 83% of students with abnormal menstrual cycles experiencing anemia. This can occur because students experience menstrual disorders with short menstrual cycles, long periods of menstruation and abnormal bleeding, causing students to experience heavy blood loss during menstruation (Nofianti et al. , 2. This is also in line with research conducted by (Studi et al. , involving 62 adolescent girls at SMA Muhammadiyah 7 Yogyakarta which resulted in 1% of students with abnormal menstrual duration experiencing anemia. The study also explained that adolescent girls who experienced abnormal menstrual duration had a 7. 556 times greater risk of anemia compared to adolescent girls who experienced normal menstrual Adel Viona, et all : Description of Menstrual Pattern Based on Anemia Status in Public Junior High School Students 14 Denpasar INTERNASIONAL CONFERENCE ON MULTIDISCIPLINARY APPROACHES IN HEALTH SCIENCE VOLUME 1 TAHUN 2023. ISSN 3032-4408 (Onlin. https://ejournal. poltekkes-denpasar. id/index. php/icmahs Research conducted by Silvia, involving 70 adolescent girls at SMK Negeri 10 Semarang resulted in a relationship between the cycle and length of menstruation with the incidence of anemia (Silvia et al. , 2. Abnormal menstrual cycles are a factor in Losing a lot of blood during menstruation can cause anemia. This is because land loss causes iron stores in the body to decrease and absorption of iron into the body is low so that it cannot replace iron loss during Duration of menstruation that lasts more than 7 days can cause adolescent girls to experience more iron loss (Suhariyati et al. Based on this, there is a tendency for menstrual patterns with the incidence of Based on the results of data analysis, it was found that 75% of female students experiencing abnormal menarche age had abnormal menstrual volume and 25% of female students experiencing abnormal menarche age had normal menstrual volume. This is in line with research conducted by Gultom, involving 40 high school students in Pontianak, as many as 43. of students experienced abnormal menstrual cycles and abnormal menarche age. According of chi square analysis p value = 0. 305 (> 0. states that there is no relationship between the menstrual cycle and the age of menarche (Gultom et al. , 2. This is also in line with research conducted by Fitriningtyas involving 50 female students of Pesantren Nurul Huda, which stated that 12% of students experienced a normal menstrual cycle with abnormal menarche age and 18% of students experienced an abnormal menstrual cycle with normal menarche age (Fitriningtyas et al. , 2.
