Height and weight from diagnosis, consolidation, start of maintenance, last cycle of maintenance, and off‐therapy were analyzed.</p> </sec> <sec id="pbc25411-sec-0003" sec-type="section"> <title>Results</title> <p>The 269 subjects were a median age of 3.5 years at diagnosis and 13.3 years at follow‐up. BMI% significantly increased from induction to consolidation (+17.6 ± 1.6%), start of maintenance to end‐of‐treatment (+3.3 ± 1.6%) and decreased from end‐of‐treatment to follow‐up (−3.5 ± 1.6%, ). Higher BMI% at follow‐up was associated with higher BMI% at diagnosis (<italic>P</italic> < 0.0001), but not age at diagnosis, gender, or race. Patients previously randomized to dexamethasone had a stronger association between BMI% at diagnosis and BMI% at follow‐up than those who received prednisone (<italic>P</italic> = 0.0005). At follow‐up, 39% of survivors were overweight or obese; the relative risk of overweight/obese was 1.028 (<italic>P</italic> = 0.738) compared to the general population.</p> </sec> <sec id="pbc25411-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Our study of patients with SR‐ALL found a significant increase in BMI% largely during the first month of therapy that is greater with dexamethasone than prednisone. However, after therapy, there was no increased risk of overweight/obese BMI compared to non‐cancer peers. Pediatr Blood Cancer 2015;62:1035–1041. © 2015 Wiley Periodicals, Inc.</p> </sec> </abstract>
