Abstract

We compared DXA whole body and lumbar spine bone mineral density (BMD) using manufacturers software with a body size correction which derived bone mineral content (BMC) for bone area in survivors of acute lymphoblastic leukemia in Saudi Arabia (n=51, mean age 13.5 y). With no corrections, 29 patients (57%) had lumbar spine BMD Z score <-1.0 and 21 (41%) had whole body BMD Z score <-2. After correction, only 6 (12%) had lumbar spine BMC Z score <-1.0 and 4 (8%) had whole body BMC Z score <-2. Agreement between the methods was "poor" by weighted [kappa] analysis.
