Dimensions of Religious Involvement Represent Positive Pathways in Cognitive Aging.

ABSTRACT: Older Black and Hispanic adults report more religious involvement, and religious involvement has been linked to better cognition. This study examined which aspects of religious involvement are associated with better longitudinal episodic memory and whether religious involvement offsets racial and ethnic inequalities in episodic memory. Using Health and Retirement Study data (N = 16,069), latent growth curves estimated independent indirect pathways between race and ethnicity and 6-year memory trajectories through religious attendance, private prayer, and religious belief, controlling for nonreligious social participation, depressive symptoms, chronic health diseases, age, education, and wealth. Negative direct effects of Black race and Hispanic ethnicity on memory were partially offset by positive indirect pathways through more private prayer and religious attendance. While results were significant for memory intercept and not subsequent memory change, religious attendance and private prayer were independently associated with better cognitive health among diverse older adults. Findings may inform culturally relevant intervention development to promote successful aging and reduce older adults' cognitive morbidity.

Project description:OBJECTIVE:To investigate the multifactorial processes underlying cognitive aging based on the hypothesis that multiple causal pathways and mechanisms (amyloid, vascular, and resilience) influence longitudinal cognitive decline in each individual through worsening brain health. METHODS:We identified 1,230 elderly subjects (aged ?50?years) with an average of 4.9?years of clinical follow-up and with amyloid positron emission tomography, diffusion tensor imaging, and structural magnetic resonance imaging scans from the population-based Mayo Clinic Study of Aging. We examined imaging markers of amyloid and brain health (white matter microstructural integrity and cortical thinning), systemic vascular health preceding the imaging markers, and early to midlife intellectual enrichment to predict longitudinal cognitive trajectories. We used latent growth curve models for modeling longitudinal cognitive decline. RESULTS:All the pathways (amyloid, vascular, resilience) converged through their effects on cortical thinning and worsening cognition and together explained patterns in cognitive decline. Resilience and vascular pathways (aging process, sex differences, education/occupation, and systemic vascular health) had significant impact on white matter microstructural integrity. Education/occupation levels contributed to white matter integrity through systemic vascular health. Worsening white matter integrity contributed to significant cortical thinning and subsequently longitudinal cognitive decline. Baseline amyloidosis contributed to a significant proportion of cognitive decline that accelerated with longer follow-up times, and its primary impact was through cortical thinning. INTERPRETATION:We developed an integrated framework to help explain the dynamic and complex process of cognitive aging by considering key causal pathways. Such an approach is important for both better comprehension of cognitive aging processes and will aid in the development of successful intervention strategies. ANN NEUROL 2019;86:866-877.
