The objective of this paper is to investigate the prevalence of and risk factors associated with cognitive impairment in a community-dwelling elderly population.
1000 community residents aged 65-74 years were recruited in the cross-sectional survey of associated factors of cognitive impairment in southern Taiwan. We employed a multilevel stratified sampling strategy and conducted this interview survey from April to June 2001. The survey questionnaire included background information and the Short Portable Mental Status Questionnaire. The relationship between cognitive impairment and each individual variable in personal attributes and social participation were explored.
Eight hundred and ninety-four (89.4%) subjects completed the interview and questionnaires. The cognitive impairment rate among all subjects was 4.92%. Of those surveyed, 54.98% were male and 45.02% were female, and the average age was 69.37 (SD 2.73) years. Most survey respondents (72.05%) were married, and 68.90% of the subjects did not participate in any social activities in the last 6 months. Females, those who were illiterate or did not attend school, those who had an average family income below US$860 per month, and persons who did not participate in any social activities had a significantly higher rate of cognitive impairment.
The educational level and participation in social activities were associated with the cognitive impairment among the aged community dwellers.
本文旨在调查社区老年人群中认知障碍的患病率及其相关危险因素。
在台湾南部进行的认知障碍相关因素横断面调查中，招募了1000名年龄在65 - 74岁的社区居民。我们采用了多级分层抽样策略，并于2001年4月至6月进行了此次访谈调查。调查问卷包括背景信息和简易便携式精神状态问卷。探讨了认知障碍与个人属性和社会参与中各变量之间的关系。
894名（89.4%）受试者完成了访谈和问卷。所有受试者的认知障碍率为4.92%。在接受调查的人群中，54.98%为男性，45.02%为女性，平均年龄为69.37（标准差2.73）岁。大多数受访者（72.05%）已婚，68.90%的受试者在过去6个月中未参加任何社会活动。女性、文盲或未上学的人、家庭月平均收入低于860美元的人以及未参加任何社会活动的人认知障碍率显著更高。
教育水平和社会活动参与度与社区老年居民的认知障碍有关。
