<![CDATA[Height and weight can provide an overview of a person's nutrition. Nutritional problems in adolescents can occur because of the continuation of nutritional problems at the age of children, namely iron deficiency, excess and underweight. The human body needs iron for the synthesis of the protein that carries oxygen, namely hemoglobin. Anemia occurs when the production of hemoglobin is so reduced that its levels in the blood decrease. Anemia is still a common nutritional/public health problem associated with the risk of morbidity and mortality, especially in adolescents. Anemia due to iron deficiency affects more than 2 billion people in the world. Data from Riskesdas in 2013 showed that the prevalence of anemia in Indonesia was 21.7% with patients with anemia aged 5-14 years at 26.4% and 18.4% in patients aged 15-24 years. This study aims to determine the correlation between BMI and HB levels in adolescent girls. The research location was conducted at One Roof Middle School, Mestong District, Muaro Jambi Regency from August to December 2018. This research is an analytical study with a cross sectional design. The population in this study were all young women from grade 1 to grade 3 of One Roof Junior High School. A sample of 40 adolescents was taken using the purposive sampling technique. Data analysis was carried out univariate and bivariate with Spearman correlation test.
