Childhood acute lymphoblastic leukemia achieves excellent cure rates in part due to induction chemotherapy including high dose corticosteroids. Hypertension (HTN) is a known complication of corticosteroids, but incidence and risk factors for steroid-induced HTN are poorly understood. We sought to describe these using a large pediatric health database. Of the 5578 unique patients receiving induction chemotherapy, 14.7% received anti-HTN medications during their initial hospital admission. We found that age below 1 year, obesity, secondary diabetes mellitus, and abnormal glucose were associated with developing steroid-induced HTN. We also found that ICD-9 codes had poor sensitivity for detecting treatment of HTN, suggesting underreporting by physicians.
