Abstract

Background: With the aging of society, cognitive impairment in elderly people is becoming increasingly common and has caused major public health problems. The screening of cognitive impairment in elderly people and its related influencing factors can aid in the development of relevant intervention and improvement strategies.

Methods: In this study, stratified random cluster sampling was used to conduct a cross-sectional survey of elderly individuals aged 65 years in Chengdu, Sichuan Province, through an electronic questionnaire from November 2022 to November 2023. Descriptive analysis and logistic regression analysis were used to investigate cognitive impairment and its relevant influencing factors.

Results: Among the 16,609 elderly people, 7524 (45.3%) were males and 9085 (54.7%) were females, with an average age of 73.6 ± 6.5 years (age range 65-101 years). The average years of education was 5.9 ± 6.2 years, and the proportion of individuals with cognitive impairment was 13.1%. With increasing age, the risk of cognitive impairment increased significantly. The risk factors for cognitive impairment in elderly individuals included advanced age, hypertension, heart disease, diabetes, cerebrovascular disease, depressive symptoms, and anxiety symptoms, while the protective factors included higher education level, married status, and greater life satisfaction.

Conclusion: Cognitive impairment in elderly individuals in Chengdu is serious. We can intervene in and improve cognitive impairment in elderly people by controlling blood pressure and blood sugar, treating depressive and anxiety symptoms and developing community colleges for elderly people and increasing satisfaction with life.

成都市老年人认知功能障碍的影响因素：基于AD8的横断面研究

背景：随着社会的老龄化，老年人认知功能障碍日益普遍，并已引起重大的公共卫生问题。筛查老年人认知障碍及其相关影响因素有助于制定相应的干预和改善策略。方法：本研究采用分层随机整群抽样的方法，于2022年11月至2023年11月对四川省成都市65岁以上老年人进行横断面调查。采用描述性分析和logistic回归分析探讨认知功能障碍及其相关影响因素。结果：16609名老年人中，男性7524人（45.3%），女性9085人（54.7%），平均年龄73.6±6.5岁（65 ~ 101岁）。平均受教育年限为5.9±6.2年，存在认知障碍的比例为13.1%。随着年龄的增长，认知障碍的风险显著增加。老年人认知功能障碍的危险因素包括高龄、高血压、心脏病、糖尿病、脑血管疾病、抑郁症状和焦虑症状，保护因素包括高学历、婚姻状况和较高的生活满意度。结论：成都市老年人认知功能障碍较为严重。我们可以通过控制血压和血糖，治疗抑郁和焦虑症状，发展老年人社区学院，提高对生活的满意度来干预和改善老年人的认知障碍。
