Black people in the United States (US) experience an increased risk of being diagnosed with Alzheimer's disease and related dementias (ADRD). More research is needed on psychosocial factors that may contribute to racial disparities in rates of ADRD. Past work has identified a relationship between quality of life (QoL) and ADRD risk and also found that religion/spirituality (R/S) participation protects against ADRD. The present analysis clarifies previous findings by examining how QoL factors and a unique sociocultural experience (i.e. R/S among Black people in the US) affect ADRD risk.
This was a cross-sectional analysis using data from the Health and Retirement Study, a nationally representative longitudinal dataset with an oversampling of Black adults. We conducted logistic regression and causal mediation analyses using R/S, QoL, and ADRD.
Higher levels of negative affect are significantly associated with increased ADRD risk while more frequently attending religious services is significantly associated with reduced ADRD risk. Further, positive affect trended toward reducing ADRD risk. Positive/negative affect partially mediated the relationship between religious services attendance and ADRD risk.
These findings demonstrate the importance of involving those experiencing negative effects in R/S for reducing the ADRD burden for Black people in the US.
美国黑人被诊断患有阿尔茨海默病及相关痴呆症（ADRD）的风险增加。对于可能导致ADRD发病率存在种族差异的社会心理因素，需要开展更多研究。过去的研究已经确定了生活质量（QoL）与ADRD风险之间的关系，还发现宗教/精神信仰（R/S）参与可预防ADRD。本分析通过研究生活质量因素和一种独特的社会文化体验（即美国黑人中的宗教/精神信仰）如何影响ADRD风险，对先前的研究结果进行了阐释。
这是一项横断面分析，使用了来自健康与退休研究的数据，该研究是一个具有全国代表性的纵向数据集，对黑人成年人进行了过度抽样。我们使用宗教/精神信仰、生活质量和ADRD进行了逻辑回归和因果中介分析。
较高水平的消极情绪与ADRD风险增加显著相关，而更频繁地参加宗教仪式与ADRD风险降低显著相关。此外，积极情绪有降低ADRD风险的趋势。积极/消极情绪部分介导了参加宗教仪式与ADRD风险之间的关系。
这些发现表明，让那些经历负面影响的人参与宗教/精神信仰活动对于减轻美国黑人的ADRD负担具有重要意义。
