Prevalence and correlates of subjective cognitive decline in older United States military Veterans: Results from the National Health and Resilience in Veterans Study.

Subjective cognitive decline (SCD) has been associated with increased risk for mild cognitive impairment and dementia. Using data from the National Health and Resilience in Veterans Study (NHVRS), we examined the prevalence and sociodemographic, health, and psychosocial correlates of SCD among 3001 older US Veterans. Results of a relative importance analysis of statistically significant correlates of SCD revealed that greater severity of insomnia, posttraumatic stress symptoms, and loneliness, as well as lower grit and resilience, accounted for >75% of the explained variance in SCD. Results provide insight into modifiable psychosocial factors associated with SCD among older US Veterans.
