Cardiovascular disease (CVD) remains a leading cause of death in the U.S. and is often final pathway to death among people living with multimorbidity. This study examined the association between multimorbidity and mortality, specifically CVD and all-cause mortality, among U.S. adults aged 50 years of age and older. Data from the 1999-2018 National Health Interview Survey linked with the National Death Index were analyzed. Primary outcomes were all-cause and CVD mortality (due to heart disease and cerebrovascular disease) years, measured from the interview to death or December 31, 2019. Cox regression models assessed mortality risk differences, adjusting for age, sex, marital status, poverty-income ratio, and education.  \nAmong 264,400 adults (39.02% with 0-1 chronic conditions; 60.98% with ≥2 conditions), the median follow-up was 7 years (IQR: 4-12). All-cause mortality was 30.65 per 1,000 person-years and CVD mortality was 9.91 per 1,000 person-years.  \nMultimorbidity was linked to higher mortality rate (all-cause:  \n38.66 vs. 19.75 and CVD: 12.79 vs. 5.70, per 1,000 person-years).  \nFully adjusted models showed a 43% higher all-cause mortality risk (95% CI: 1.40-1.46) and 59% higher CVD mortality risk (95% CI: 1.52-1.65) for those with multimorbidity. Additionally, each additional comorbidity was associated with an increased risk in all-cause (aHR:1 .06; 95% CI: 1.04–1.09) and CVD mor  \ntality (aHR: 1.14; 95% CI: 1.10–1.18). Integrated models of care considering multidisciplinary management is crucial to improve health outcomes and mitigate mortality risk among older adults with multimorbidity.","cbCaiscuBf6scGpi","https://ap.wps.com/l/cbCaiscuBf6scGpi","pdf",51336,"English","# Abstract\n## Study design and data sources\n## Outcomes and statistical approach\n## Key findings and implications","[{\"question\":\"What relationship does the study examine between multimorbidity and mortality?\",\"answer\":\"It assesses how multimorbidity is associated with both all-cause mortality and cardiovascular (heart disease and cerebrovascular disease) mortality among U.S. adults aged 50 and older.\"},{\"question\":\"Which datasets were used for the analysis?\",\"answer\":\"The study used data from the 1999-2018 National Health Interview Survey linked with the National Death Index.\"},{\"question\":\"How were mortality risks estimated and what variables were adjusted for?\",\"answer\":\"Cox regression models estimated differences in mortality risk and adjusted for age, sex, marital status, poverty-income ratio, and education.\"}]","All-CAUSE AND CARDIOVASCULAR MORTALITY IN OLDER ADULTS WITH MULTIMORBIDITY - 1999-2018 NATIONAL SURVEY | PDF",1790646063]
