主观认知下降（SCD）是一种自我感知的认知下降，可能进展为轻度认知障碍或阿尔茨海默病。SCD可能与日常功能障碍和心理困扰有关。以前的研究表明，功能障碍和SCD之间的关联通过精神不健康的日子（MUD）。然而，收入水平是否会影响MUDs的中介作用还不太清楚。本研究通过MUD检查了主观功能困难与SCD几率之间的关联，以及中介效应是否受收入水平的调节。横断面数据来自2019年行为风险因素监测系统（N = 13，160名65岁以上的老年人; 7，370名女性）。SCD通过过去12个月内更频繁或更严重的记忆丧失和混乱来评估。主观功能困难代表日常活动困难。MUD表示一个人在过去30天内感到精神不适的日子。我们使用路径分析和5,000个自举置信区间和逻辑回归，根据主观功能困难和MUD对SCD的风险进行分类。通过MUD的介导，主观功能困难与SCD呈正相关（B = 0.119，95% CI 0.102，0.137）。在考虑协变量后，我们发现更大的主观功能困难与SCD几率的2.50倍相关（AOR = 2.50; 95% CI：2.14，2.91）; MUD与SCD报告几率的1.06倍相关（AOR = 1.06; 95% CI：1.05，1.07）。收入水平调节MUD在主观功能困难-SCD关系中的间接影响，收入<15，000美元显示出最显著的影响。收入≥ 50，000美元的人自我报告的SCD低于收入<15，000美元的人。我们的研究扩展了以前的研究结果，证明了更大的主观功能困难与更高的SCD几率相关，通过更频繁的MUD，更高的收入水平与更多的SCD报告相关。
Subjective cognitive decline (SCD) is a self-perceived decline in cognition that may progress to mild cognitive impairment or Alzheimer's disease. SCD may be associated with difficulties in daily functioning and psychological distress. Previous research has shown the association between functional difficulties and SCD via mentally unhealthy days (MUDs). However, whether income levels influence the mediation effect of MUDs is less understood. This study examined the association between subjective functional difficulties and the odds of SCD through MUDs, and whether the mediation effect was moderated by income levels. Cross-sectional data were obtained from the 2019 Behavioral Risk Factor Surveillance System (N = 13,160 older adults aged 65+; 7,370 women). SCD was assessed by more frequent or worse memory loss and confusion in the past 12 months. Subjective functional difficulties represented difficulties with daily activities. MUDs denoted the days that a person felt mentally unwell within the past 30 days. We used path analysis with 5,000 bootstrapped confidence intervals and logistic regression to classify the risks of SCD based on subjective functional difficulties and MUDs. Subjective functional difficulties were positively associated with SCD through mediation by MUDs (b = 0.119, 95% CI 0.102, 0.137). After accounting for covariates, we found that greater subjective functional difficulties were associated with 2.50 times the odds of SCD (AOR = 2.50; 95% CI: 2.14, 2.91); MUDs were related to 1.06 times the odds of SCD reporting (AOR = 1.06; 95% CI: 1.05, 1.07). Income levels moderated the indirect effect of MUDs in the subjective functional difficulties-SCD relationship, with an income of <$15,000 showing the most prominent effect. Those earning ≥$50,000 self-reported a lower SCD than those earning <$15,000. Our study extends previous findings by demonstrating that greater subjective functional difficulties are associated with higher odds of SCD through more frequent MUDs, with higher income levels being associated with more SCD reporting.
