Abstract

Introduction: Given the rapid population ageing, the cognitive healthcare needs of older adults warrant attention. This study reports on the findings of the Hong Kong Mental Morbidity Survey for Older People (HKMMSOP), which evaluated the prevalence of neurocognitive disorders (NCD) and associated health factors that may inform primary care risk assessment and intervention.

Methods: The HKMMSOP recruited 4871 participants aged 60 years or above through random sampling in Hong Kong during 2019 and 2023, including 4368 community-dwelling and 503 residential care home residents. Participants were assessed for cognitive function and mental status and completed health and lifestyle questionnaires. The prevalence of NCD and associated factors were evaluated with reference to the 2022 Hong Kong population.

Results: The age- and gender-adjusted prevalences of mild and major NCD were 21.8% and 9.7%, respectively, among adults aged 60 years or above in Hong Kong. Approximately 70% of residents in long-term care (LTC) institutions had major NCD. Chronic diseases, sarcopenia risk, sensory impairments, and specific lifestyle habits were associated with cognitive function in logistic regression analyses adjusted for demographic confounders (P<0.05). Specialised medical services, including psychiatric care, were used by approximately 40% of community participants with major NCD.

Conclusion: A range of NCD is prevalent in both community and LTC settings, with the highest rates observed among the oldest-old. To improve functional independence, community primary healthcare should prioritise early cardiovascular disease management, physical health maintenance, correction of sensory impairments, and promotion of intellectual and social engagement. For effective healthcare planning for frail older adults living in LTC institutions, the complex needs of nursing home residents with NCD should be addressed.

香港社区及安老院舍的轻度及重度神经认知障碍患病率:多维风险因素评估及基层护理的干预措施
引言:在人口快速老龄化的背景下,老年人的认知保健需求值得关注。本研究报告了香港老年人精神发病率调查(HKMMSOP)的结果,该调查评估了神经认知障碍(NCD)的患病率和相关的健康因素,这些因素可能为初级保健风险评估和干预提供信息。方法:HKMMSOP于2019年至2023年在香港通过随机抽样的方式招募了4871名60岁及以上的参与者,其中社区住宅居民4368名,住宅护理院居民503名。研究人员评估了参与者的认知功能和精神状态,并完成了健康和生活方式问卷。以2022年香港人口为参考,评估非传染性疾病的患病率及相关因素。结果:香港60岁及以上成年人轻度和重度非传染性疾病的年龄和性别调整患病率分别为21.8%和9.7%。大约70%的长期护理(LTC)居民患有严重的非传染性疾病。经人口统计学混杂因素调整后的logistic回归分析显示,慢性病、肌肉减少症风险、感觉障碍和特定的生活习惯与认知功能相关(结论:一系列非传染性疾病在社区和LTC环境中都很普遍,其中老年人的发病率最高)。为了提高功能独立性,社区初级卫生保健应优先考虑早期心血管疾病管理、身体健康维护、矫正感觉障碍以及促进智力和社会参与。对于生活在长期社区的体弱老年人而言,有效的医疗保健规划应解决患有非传染性疾病的养老院居民的复杂需求。
