Body mass index associated with glucocorticoid-related weight gain in children with rheumatic disease on high-dose prednisone

Clin Exp RheumatolPublished Retrospective cohort study

Authors' conclusion

Greater BMI was a predictor of severe GC-related obesity for children with rheumatic disease requiring moderate to high-dose prednisone therapy.

Study context

Follow-up
12 months
Methodological detailsretrospective chart review, single-centre, binary logistic regression
  • Retrospective chart review
  • Single-centre
