A new study published in the Journal of Gerontology found that Asian Americans no longer report better health outcomes than white Americans among US adults aged 50 and over. The prevalence of disability declined across every other racial group, but remained stagnant among US-born Asians since 2005.
The study analyzed 14.7 million excess US deaths from 1980 to 2023, finding that rates remained higher than pre-pandemic levels. Excess deaths during and after the pandemic were largely driven by pre-existing causes such as drug overdose, firearm injury, and cardiometabolic disease.
US survivors of adolescence and young adult cancer experience significantly worse mental health outcomes into middle age and older adulthood. Cancer clinicians should acknowledge this mental health burden and take steps to address it.
