National estimates of mental health needs among non-elderly adult cancer survivors.
e19103 Background: As advancements in cancer therapies expand the population of long-term cancer survivors, it is important to understand long-term mental health (MH) outcomes associated with cancer experience. This study used a U.S. nationally-representative sample of adult cancer survivors to assess and compare MH outcomes across age groups. Methods: We used the 2015-2017 National Survey of Drug Use and Health to identify respondents aged 18-64 years who reported a history of cancer (survivors) or never had cancer. MH outcomes were operationalized as events in past year of: major depressive episodes, serious psychological distress, suicidal thoughts, suicidal plans, suicidal attempts, any mental illness, and serious mental illness. We compared these outcomes between survivors and those without cancer in adjusted regression analyses, controlling for respondents’ demographic (gender, race/ethnicity) and socioeconomic (health insurance, employment, education status, marital status) characteristics. All analyses were stratified by age group (18-34, 35-49, and 50-64 years). Results: When comparing 2,656 survivors and 112,952 adults without cancer within each age group, survivors had elevated prevalence of MH problems in in five of the seven domains of adverse MH measures. Among young adults (aged 18-34 years), survivors were more likely than their noncancer counterparts to experience major depressive episodes (18.1% versus 9.6%, p< 0.001), serious psychological distress (34.2% versus 17.9, p< 0.001), suicidal thoughts (10.5% versus 7.0%, p= 0.011), any mental illness (41.1% versus 23.3%, p< 0.001), and serious mental illness (13.2% versus 5.9%, p< 0.001) in the past year. These differences persisted in adjusted analyses ( p-values < 0.01). While similar survivor-comparison differences were observed among older groups, the magnitude of these differences was smaller. When comparing MH outcomes across age groups among survivors, young adult survivors had the highest likelihood of experiencing MH problems across all seven domains of adverse MH measures ( p-values < 0.05). Conclusions: This population-based study shows elevated prevalence of MH problems among adult cancer survivors, as compared to the general noncancer population. We also identified a clear age gradient in the prevalence of MH problems, with young adult survivors exhibiting the highest prevalence of adverse MH outcomes. Our findings highlight the importance of developing strategies to ensure early detection and screening of mental illness and improve access to MH treatment for cancer survivors.
