摘要

背景:主观认知衰退(SCD)是认知正常个体自我报告的认知退化感觉。成年后的认知功能一直保持稳定,直到40岁左右;此后,个体更有可能经历认知能力下降。SCD被认为是阿尔茨海默病和其他形式痴呆的可能早期征兆。早期发现和干预SCD可以延缓轻度认知障碍和痴呆的发生。针对不同国家的SCD现象,已经开发和评估了几种工具;然而,香港的研究结果有限。目的:调查香港中老年人慢性阻塞性肺病的患病率,并探讨导致其发生的相关因素。方法:于2023年12月至2024年1月对200名50岁及以上的香港居民进行横断面调查。受访者填写了一份调查问卷,收集了包括性别、年龄、教育程度和健康状况在内的人口统计信息。他们还完成了主观认知能力下降问卷-21。本研究采用描述性分析、logistic分析及因子分析。结果:共收集200份样本,其中122份被分类为SCD,患病率为61%,超过邻国。SCD与自评健康评分相关。Cronbach 's alpha为0.905。研究结果表明,两个计分组对所有问题的反应模式存在显著差异。因子分析结果证实了四因子结构的可靠性,增强了量表的强度。结论:本研究分析了香港中老年人患慢性阻塞性肺病的情况,并探讨了各种因素与慢性阻塞性肺病的关系。从问卷调查中获得的初步见解,将为未来制定更全面和有效的解决方案提供参考,以解决香港老年人认知能力下降的问题。

Subjective Cognitive Decline Among Middle-Aged and Older Adults in Hong Kong: A Cross-Sectional Study

Subjective Cognitive Decline Among Middle-Aged and Older Adults in Hong Kong: A Cross-Sectional Study

Background: Subjective cognitive decline (SCD) is a self-reported perception of cognitive deterioration in individuals who are cognitively normal. Cognitive functions keep steady during adulthood up until around age 40; thereafter, individuals are more likely to experience cognitive decline. SCD is viewed as a possible early sign of Alzheimer’s disease and other forms of dementia. Early detection and intervention addressing SCD could delay the onset of mild cognitive impairment and dementia. Several tools have been developed and evaluated for the phenomenon of SCD in different countries; however, limited research findings can be found in Hong Kong.

Objective: To investigate the prevalence of SCD among middle-aged and older adults in Hong Kong and identify the related factors contributing to its occurrence.

Methods: A cross-sectional survey was undertaken from December 2023 to January 2024 to 200 individuals living in Hong Kong aged 50 years or older. The respondents filled out a questionnaire that collected demographic information, including gender, age, education level and health status. They also completed the Subjective Cognitive Decline Questionnaire-21. Descriptive analysis, logistic analysis and factor analysis were conducted in this study.

Results: A total of 200 samples were collected, of which 122 were classified as having SCD, leading to a prevalence rate of 61% that exceeds that of neighbouring countries. SCD was correlated with the self-rated health score. The Cronbach’s alpha was 0.905. The findings demonstrated significant differences in response to patterns between the two scoring groups for all questions. The results of the factor analysis confirmed the reliability of the four-factor structure, reinforcing the strength of the scale.

Conclusion: The study analysed the prevalence of SCD among middle-aged and older adults in Hong Kong as well as explored the relationship between various factors and SCD. The initial insights gained from the questionnaire will inform the future development of more comprehensive and effective solutions to address cognitive decline in older adults in Hong Kong.
