^aAll statistical tests were 2-sided, and all P values were calculated using the Pearson chi-square test statistic, and all percentages were column percentages.

^bThe comparison group consisted of nonelderly individuals without a cancer history.

^cThe comparison group consisted of elderly individuals without a cancer history.

^dThe number of chronic conditions was defined as the sum of the following conditions that a respondent was ever told by a physician or other health professional that s/he had: arthritis, asthma, diabetes, emphysema, coronary heart disease, hypertension, stroke, angina pectoris, and heart attack. High cholesterol was not included because of the inconsistency of the availability of this variable across years.

^eAmong nonelderly cancer survivors who had any private health insurance during the survey year, 41% of those who were recently diagnosed and 64% of those who were previously diagnosed had high-deductible insurance plans.
