Iron deficiency and fatigue in adolescent females with heavy menstrual bleeding

Iron deficiency and fatigue are common problems in adolescent females. Heavy menstrual bleeding (HMB) is associated with both iron deficiency and fatigue. The aim of this study was to define baseline ferritin values and fatigue symptoms in a population of young females with excessive menstrual blood loss, as compared to healthy controls. The study population included 11 to 17-year-old menstruating females presenting to an Adolescent Gynaecology Clinic, Menorrhagia Clinic or Sports Medicine clinic. To evaluate the degree and effects of menstrual blood loss, we utilized the Ruta Menorrhagia Severity Score. We investigated the symptoms of fatigue using the Fatigue Severity Scale. We evaluated possible predictors of ferritin level (age, body mass index, fatigue scores and Menorrhagia Severity Score) using generalized linear models. A total of 48 adolescents with HMB and 102 healthy adolescents completed the study. Iron deficiency and elevated fatigue scores were common findings in young women with HMB. Both fatigue severity scores and menorrhagia severity scores were significantly higher in young women with HMB as compared to healthy controls. In adolescents with HMB, 87.5% had ferritin levels 40ngmL1, and 29.2% had ferritin levels 15ngmL1. Our generalized linear models did not identify any significant univariate relationships between ferritin levels and patient age, body mass index, fatigue score or menorrhagia score. Iron deficiency and symptoms of fatigue are common findings in young women with HMB. Fatigue severity scores are significantly higher in young women with HMB as compared to healthy controls.
