项目摘要
7. PROJECT SUMMARY/ABSTRACT
Emerging evidence suggests that sexual and gender minority populations are at increased risk for Alzheimer’s
disease and related dementias (ADRD). This may be due, at least in part, to the cumulative impact of minority
stress;; related social isolation and loneliness;; and barriers to care and support services. Social support, on the
other hand, has emerged as a protective factor in the face of minority stress, and as a predictor of successful
cognitive aging among the general population. However, few studies have assessed the social support networks
of sexual and gender minorities in detail to determine the specific support characteristics that facilitate cognitive
reserve and resilience. The proposed study will fill this gap by comparing the stress, social support networks,
and aging-related cognition of a newly recruited sample of sexual and gender minority adults (n = 300, age 25-
85) to those of a matched heterosexual, cisgender sample (n = 300) enrolled in an ongoing longitudinal study of
aging and cognitive reserve (the Reference Ability Neural Networks or RANN study). In addition, the proposed
study will conduct secondary analysis of MRI data collected in RANN to explore differences in brain features
between minority and majority groups, generating hypotheses for future research. The specific aims are: (1) To
compare stress (perceived general stress and minority stress related to one or more marginalized identities) and
cognitive performance across multiple domains in newly recruited sexual / gender minority adults and matched
heterosexual, cisgender adults enrolled in the RANN study;; (2) To compare social network characteristics of
sexual / gender minority adults to those of matched heterosexual, cisgender adults, and examine within- and
between-group differences in social support based on sexual orientation, gender identity, and age;; (3) Across
both identity groups (N = 600), to examine the role of minority stress, social support, resources and wellbeing in
development of cognitive reserve and resilience (i.e., how these assets moderate the effects of minority stress
and aging on health and cognitive functioning);; and (4) In an exploratory analysis, to evaluate differences
between sexual / gender minority (n > 40) and matched heterosexual, cisgender RANN participants in MRI-
measured brain features and their relation to stress, social network characteristics, cognitive functioning, and
risk for incident ADRD. We expect that understanding differences and similarities in the social networks of
minority and majority adults and the relationship of these characteristics to stress and aging-related cognition
will enable us to identify modifiable factors associated with cognitive reserve and resilience, informing future
interventions to prevent cognitive decline and ADRD.
7. 项目概要/摘要
新证据表明性少数群体患阿尔茨海默病的风险增加
疾病和相关痴呆症(ADRD)。这可能至少部分归因于少数群体的累积影响。
压力;相关的社会孤立和孤独;以及护理和支持服务的障碍。
另一方面,已成为面对少数群体压力时的保护因素,并成为成功的预测因素
然而,很少有研究评估社会支持网络。
详细了解性少数群体的情况,以确定促进认知的具体支持特征
拟议的研究将通过比较压力、社交支持网络、
新招募的性少数和性别少数成年人样本(n = 300,年龄 25-
85) 参加一项正在进行的纵向研究的匹配异性恋、顺性别样本 (n = 300)
衰老和认知储备(参考能力神经网络或 RANN 研究)。此外,建议。
研究将对 RANN 中收集的 MRI 数据进行二次分析,以探索大脑特征的差异
少数群体和多数群体之间的关系,为未来的研究提出假设,具体目标是:(1)
比较压力(感知到的一般压力和与一个或多个边缘化身份相关的少数压力)和
新招募的性/性别少数成年人和匹配的跨多个领域的认知表现
参加 RANN 研究的异性恋、顺性别成年人;(2) 比较不同性别的社交网络特征
将性/性别少数成年人与匹配的异性恋、顺性别成年人进行比较,并在内部和外部进行检查
基于性取向、性别认同和年龄的群体间社会支持差异;(3) 跨群体
两个身份群体(N = 600),以检查少数群体压力、社会支持、资源和福祉的作用。
认知储备和复原力的发展(即这些资产如何缓解少数群体压力的影响
以及衰老对健康和认知功能的影响);以及 (4) 在探索性分析中评估差异
MRI 中的性/性别少数 (n > 40) 和匹配的异性恋、顺性别 RANN 参与者之间
测量大脑特征及其与压力、社交网络特征、认知功能和
我们期望了解社交网络中的差异和相似之处。
少数和大多数成年人以及这些特征与压力和衰老相关认知的关系
将使我们能够识别与认知储备和复原力相关的可修改因素,为未来提供信息
预防认知能力下降和 ADRD 的干预措施。
