Abstract

Objective

Self-rated health (SRH) is a predictor for poor health outcomes and cognition. Older adults with type 2 diabetes mellitus (T2D) have multi-morbidity and greater cognitive impairment. In the present study we investigated the association of SRH with cognitive decline and brain pathology in older adults with T2D.

Methods

Participants (n = 1122) were from the Israel Diabetes and Cognitive Decline study, and SRH was categorised as low (n = 202), moderate (n = 400) or high (n = 520). Cognition was measured by four cognitive domains: episodic memory, executive functions, language, and attention/working memory. Global cognition was the average of the cognitive domains. Statistical models adjusted for sociodemographic, cardiovascular, and clinical variables. In a randomly selected subsample (n = 230) that had magnetic resonance imaging, we examined relationships between baseline SRH and brain characteristics (white matter hyperintensities [WMHs], hippocampal, and total grey matter [GM] volumes).

Results

Low SRH was associated with a decline in executive functions, which accelerated over time when compared to high SRH (est = −0.0036; p = <0.001). Compared to high SRH, low SRH was associated with a faster decline in global cognition (est = −0.0024; p = 0.009). Low SRH at baseline was associated with higher volumes of WMHs (est = 9.8420; p < 0.0008). SRH was not associated with other cognitive domains, or with hippocampal and total GM.

Conclusions

Low SRH is associated with cognitive decline in T2D older adults and may serve as a risk assessment. WMHs may represent an underlying mechanism.

自评健康状况差与 2 型糖尿病老年人认知能力下降速度加快和小血管疾病增多有关

自评健康（SRH）是不良健康后果和认知能力的预测因素。患有 2 型糖尿病（T2D）的老年人多病缠身，认知障碍也更严重。在本研究中，我们调查了 SRH 与患有 T2D 的老年人认知能力下降和大脑病理学的关系。
