摘要

背景大量研究表明,人们的健康存在社会经济差异。健康行为被认为是缓解社会经济差异的有效策略。然而,社会经济地位(SES)和生活方式行为(LBs)对中国老年人认知能力的独立或联合关系尚不清楚。因此,本研究旨在揭示SES和生活行为对中国老年人认知障碍的影响。方法采用2017-2018年中国健康长寿纵向调查数据。根据家庭人均年收入、教育程度和职业,采用潜类分析法创建 SES。在计算 LB 分数时考虑了六个 LB。为了研究剂量-反应关系,我们使用了限制性三次样条来建立 LB 分数与认知障碍的关联模型。LB 评分分为三组:不健康生活方式组、中等生活方式组和健康生活方式组。结果 在 10,116 名参与者中,1,872 人(18.51%)被记录为有认知障碍。在对多变量混杂因素进行调整后,与高社会经济地位的参与者相比,低社会经济地位的参与者出现认知障碍的风险更高[比值比(OR):1.385;95% 置信区间(CI):1.137-1.689]。与生活方式不健康的人相比,坚持健康生活方式的人患认知障碍的风险较低(OR:0.198;95%CI:0.150-0.263)。LB 分数与认知障碍之间存在非线性关系(Pnonlinearity =0.001),表明当 LB 超过两个时,对认知障碍有保护作用。与社会经济地位低、生活方式不健康的人群相比,社会经济地位高、生活方式健康的人群发生认知障碍的风险最低(OR:0.123;95% CI 0.073-0.207)。健康的生活方式可减轻社会经济不平等对认知障碍的影响,强调了改变生活方式在减轻认知障碍疾病负担方面的重要作用,尤其是在社会经济地位较低的老年人群中。

Independent and Joint Associations of Socioeconomic Status and Lifestyle behaviors with Cognitive Impairment among Elderly Chinese Population

Background

Numerous studies have shown that there are socioeconomic disparities in people’s health. Health behavior is considered to be an effective strategy to alleviate socioeconomic differences. However, the independent or joint relationship between socioeconomic status (SES) and lifestyle behaviors (LBs) on the cognition of Chinese elderly are not clear. Therefore, this study aimed to reveal the impact of SES and LBs on cognitive impairment in elder Chinese.

Methods

The data from the 2017–2018 wave of Chinese Longitudinal Healthy Longevity Survey was used. SES was created using latent class analysis based on annual percapita household income, education level, and occupation. Six LBs were considered in calculating LB scores. Restricted cubic splines were used to model the association of LB scores and cognitive impairment to investigate the dose-response relationship. LB scores were divided into three groups: unhealthy, intermediate, and healthy lifestyle. Multivariate Logistic regression models were applied to explore both the independent and joint effects of SES and LB scores on cognitive impairment.

Results

Among 10,116 participants, 1,872 (18.51%) were recorded as having cognitive impariment. After adjusting for multivariable confounding factors, compared with participants of high SES, those of low SES had higher risks of cognitive impairment [Odds ratio (OR): 1.385; 95% confidence interval (CI): 1.137–1.689]. In contrast to those with unhealthy lifestyle, participants adhering to a healthy lifestyle were found to be associated with a reduced risk of cognitive impairment (OR: 0.198; 95%CI: 0.150–0.263). A non-linear relationship was observed between LB scores and cognitive impairment (Pnonlinearity =0.001), indicating a protective effect on cognitive impairment when having more than two LBs. Participants with high SES and engaged in healthy lifestyle had the lowest risk of cognitive impairment compared to those with low SES and unhealthy lifestyle (OR: 0.123; 95% CI 0.073–0.207).

Conclusion

Cognitive impairment has socioeconomic disparities among the elderly Chinese population. A healthy lifestyle may attenuate the impact of socioeconomic inequality on cognitive impairment, emphasizing the important role of LBs modification in reducing the disease burden of cognitive impairment, especially in the elderly population with low SES.
