本研究考察了认知随时间的变化与社会活动的参与和社会网络的范围之间的关系。方法资料采自1989年开始的台湾老年人口纵向研究。使用过分散泊松模型对1996年、1999年和2000年的认知障碍、社会活动、社会网络、健康状况和社会人口特征的先前测量进行了回归，以确定失败的认知任务（0-5）的数量。分析样本包括2387个个体，他们在1993- 1996年、1996- 1999年、1999-2000年三个调查区间共提供了4603个观测值。结果在调整了既往认知障碍、基线健康状况和社会人口因素后，参加过1 - 2次社会活动的被调查者比没有参加过社会活动的被调查者认知任务失败率低13% (P < 0.01)；参与三种或三种以上活动的人的认知任务失败率降低33% （P < 0.001）。相比之下，社交网络测试与认知障碍无关。
Background This study examines how changes in cognition over time are related to participation in social activities and the extent of social networks.Methods Data are drawn from a population-based, longitudinal study that began in 1989 among elderly Taiwanese. An over-dispersed Poisson model is used to regress the number of failed cognitive tasks (0-5) in 1996, 1999, and 2000 on prior measures of cognitive impairment, social activities, social networks, health status, and sociodemographic characteristics. The analysis sample comprises 2387 individuals, who contribute a total of 4603 observations across three survey intervals (1993-96, 1996-99, 1999-2000).Results After adjusting for prior cognitive impairment, baseline health status, and sociodemographic factors, respondents who participated in one or two social activities failed 13% fewer cognitive tasks (P < 0.01) than those with no social activities; those who engaged in three or more activities failed 33% fewer cognitive tasks (P < 0.001). In contrast, none of the social network measures was related to cognitive impairment.Conclusions Despite a social structure where elderly persons often live with their children and social interaction is likely to be more family-centered than in western countries, data from Taiwan suggest that participation in social activities outside the family may have a bigger impact on cognitive function than social contacts with family or non-relatives.
