RESUMO
OBJECTIVE: To compare the prevalence of overweight in a cohort of pediatric survivors of cancer with that in the general population. STUDY DESIGN: We reviewed the charts of 441 cancer survivors followed at a Canadian tertiary care pediatric hospital and calculated their most recent body mass index. We compared this cohort with population data generated from the Canadian Community Health Survey. RESULTS: At a median age of 14.7 years (range, 3.4 to 19.5 years) and a median time from diagnosis of 9.7 years (range, 3.4 to 19.2 years), 140 of 441 patients (31.7%) were overweight or obese. Only 12 of the 441 patients (2.7%) were underweight. Males age 6 to 11 years (odds ratio [OR] = 2.29; 95% confidence interval [CI] = 1.36 to 3.86; P < .001) and male survivors of acute lymphoblastic leukemia (OR = 1.55; 95% CI = 1.03 to 2.52; P = .04) were more likely to be overweight than the general population. No other age or diagnostic group had an increased risk of overweight. CONCLUSIONS: The prevalence of overweight was not increased in this cohort compared with the general population. However, almost 1/3 of these patients are overweight, necessitating a clinical and research focus on preventing and combating overweight in childhood cancer survivors.
