The role of spirituality and religiosity on the cognitive decline of community-dwelling older adults: a 4-year longitudinal study.

ABSTRACT

OBJECTIVES: This study aims to assess whether having religious beliefs, attending religious services and using spiritual-religious coping (SRC) are longitudinally associated with cognitive decline in community-dwelling older adults. METHODS: A 4-year longitudinal study of 261 Brazilian older adults was conducted. Hierarchical adjusted linear regression models and logistic regression models were performed to evaluate the longitudinal effects of religious beliefs, church attendance and positive and negative SRC on cognitive decline. RESULTS: The findings revealed that spiritual and religious beliefs at baseline could affect cognitive function in two different ways. When older adults use religiosity and spirituality (RS) in a functional positive manner, it results in better cognitive outcomes and a slower rate of decline. However, when used in a negative manner, it results in worse cognitive outcomes. CONCLUSION: These results could help health care professionals address SRC among older adults, particularly those at a higher risk of cognitive decline. Considering that RS is very important for older adults, health care professionals should be aware of the beliefs of their patients and address RS in clinical practice.
