A Population-Based Study of Childhood Cancer Survivors’ Body Mass Index

[摘要] Background.Population-based studies are needed to estimate the prevalence of underweight or overweight/obese childhood cancer survivors.Procedure.Adult survivors (diagnosed ≤20 years) were identified from the linked Utah Cancer Registry and Utah Population Database. We included survivors currently aged ≥20 years and ≥5 years from diagnosis(N=1060), and a comparison cohort selected on birth year and sex(N=5410). BMI was calculated from driver license data available from 2000 to 2010. Multivariable generalized linear regression models were used to calculate prevalence relative risks (RR) and 95% confidence intervals (95% CI) of BMI outcomes for survivors and the comparison cohort.Results.Average time since diagnosis was 18.5 years(SD=7.8), and mean age at BMI for both groups was 30.5 (survivorsSD=7.7, comparisonSD=8.0). Considering all diagnoses, survivors were not at higher risk for being underweight or overweight/obese than the comparison. Male central nervous system tumor survivors were overweight (RR=1.12, 95% CI 1.01–1.23) more often than the comparison. Female survivors, who were diagnosed at age 10 and under, had a 10% higher risk of being obese than survivors diagnosed at ages 16–20(P<0.05).Conclusion.While certain groups of childhood cancer survivors are at risk for being overweight/obese, in general they do not differ from population estimates.
