a Adjusted mortality from the underlying cause of death was calculated by assuming that data reporting (cause specificity and selection of underlying cause of death from multiple causes of death) remained unchanged from 1999 to 2016.
Notes: We extracted age-standardized mortality data from of the United States Centers for Disease Control and Prevention online databases;2 causes of death are recorded by International Statistical Classification of Diseases and Related Health Problems (10th revision) codes.16 Percentage change in mortality between 1999 and 2016 was calculated as: [regression coefficient × 17 ÷ (mortality in 1999) × 100%]. The total population aged 65+ years in the 50 States and District of Columbia of the United States of America was 34 797 841 in 1999 and 49 244 195 in 2016.
