Background and objectives: The health consequences of anxiety in late life have not been adequately investigated. We sought to examine the association between anxiety and death in an older tri-ethnic population.
Methods: A longitudinal population-based study of 506 older noninstitutionalized non-Hispanic Whites, non-Hispanic Blacks, and Hispanics aged 75 years or older from Galveston County.
Results: Average age was 80.8 (SD 4.4) and 50.8% were women. Older non-Hispanic Whites (21.6%) reported the highest prevalence of anxiety, followed by Hispanics (12.4%) and non-Hispanic blacks (11.3%) (P=.0001). High anxiety was significantly associated with an increased hazard of all cause death (HR 1.52; 95% CI 1.02, 2.28) and cardiovascular death (HR 1.90; 95% CI 1.06, 3.36); and was associated with an increased hazard of cancer death (HR 2.38; 95% CI 0.88, 6.45) during 5-years of follow-up.
Conclusion: There is a high prevalence of anxiety in late life. Our results indicate an association between anxiety and increased risk of death in persons aged 75 and older.
