Trends in mortality of Alzheimer's disease with comorbid hypertension in patients in the US from 1999-2020

Aims To examine temporal trends and demographic disparities in Alzheimer's disease (AD)-related mortality among adults aged ≥ 65 years with comorbid hypertension in the United States from 1999 to 2020. Materials and methods We conducted a population-based retrospective analysis using the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) Multiple Cause of Death database. Deaths involving AD (ICD-10 G30) and hypertension (ICD-10 I10-I15) were identified. Age-adjusted mortality rates (AAMRs) were assessed by sex, race/ethnicity, geographic region, urbanization level, and state. Temporal trends were evaluated using Joinpoint regression. Results Between 1999 and 2020, 409,112 deaths involving AD and hypertension were recorded. The overall AAMR increased from 14.51 per 100,000 in 1999 to 69.06 in 2020, with a decline from 2007 to 2014 followed by an increase through 2020. Females had higher AAMRs than males, and non-Hispanic Black individuals had the highest AAMR among the racial and ethnic groups examined. Conclusions AD-related mortality among older adults with comorbid hypertension increased substantially during the study period, with notable demographic and geographic disparities.
