N2 - In older adults, subjective cognitive decline (SCD) may progress to an early stage of dementia. Yet, its association with subjective daily functional difficulties in aging is less well studied by experiences of mentally unhealthy days (MUDs). Employing a cross-sectional design approach, we analyzed the Behavioral Risk Factor Surveillance System dataset on 7429 older adults with SCD (aged 65 to >80, 45% males, 55% females) to explore SCD in instrumental daily activities of living (SCD-IADLs) and healthcare access mediation by MUDs and moderated mediation by age cohort, controlling gender and education. The bias-corrected percentile bootstrap with 5000 samplings revealed that MUDs partially mediate the relationship between SCD-IADLs and healthcare access, with a 28.2% mediating effect. Age cohort moderated the relationship between healthcare access and MUDs, MUDs and SCD-IADLs. Specifically, the predictive effects from healthcare access to MUDs and MUDs to SCD-IADLs were more profound in the 70–74 age cohort.
