*
Annual percent changes were estimated on the basis of obesity rates by year, sex, and age group using Poisson regressions. P values for the interaction term between cancer status (yes/no) and time were all < .001.
†
Annual percent changes were compared with all cancer-free adults (the “Never” group).
