Objective: To explore the cognitive functions of elderly aged 60 years and above in Xiamen, whether TV watching time would affect those functions. Methods: We conducted a cross-sectional study on 3 230 registered individuals Xiamen from July to October 2016 with multi-stage random sampling method. Montreal Cognitive Assessment (MoCA) was used measure ordinal logistic regression quantify their associations time. Results: A total 2 944 respondents were included this study. The overall age them (70.14±7.81) years. 51.49% (n=1 516) all participants men. Overall, mean scores MoCA general each subdomain function 18.65±6.43 (general), 5.43±1.17 (orientation), 2.33±1.95 (memory), 1.80±1.52 (visuospatial), 1.66±1.20 (executive), 4.54±1.71 (attention), 4.09±1.64 (language). Compared who watched no more than hours per day, did not watch had worse performance general, orientation, memory, visuospatial, executive, attention, language function, OR (95%CI) values about 0.50 (0.35-0.71), 0.52 (0.37-0.73), 0.68 (0.48-0.96), 0.67 (0.47-0.96), 0.48 (0.34-0.67), 0.56 (0.41-0.77) 0.45 (0.33-0.62), respectively. As but 4 they better language, orientation respective 1.24 (1.05-1.47), 1.20 (1.02-1.41), 1.41 (1.19-1.67), 1.51 (1.28-1.77) 1.33 (1.08-1.64). Conclusion: City between day good compared or less time.目的：调查厦门市60岁及以上老年人认知功能状况，并分析看电视时长与老年人认知功能的关系。 方法：于2016年7—10月，采用多阶段随机抽样方法，选取3 230名60岁及以上的厦门市户籍老人进行问卷调查，运用蒙特利尔认知量表（MoCA）进行认知功能评估。采用有序logistic回归模型分析看电视时长与认知功能的关系。 结果：最终纳入分析的2 944名研究对象为年龄（70.14±7.81）岁，其中男性1 516名（51.49%）。认知功能总体得分为（18.65±6.43）分，其中定向力、记忆力、视空功能、执行功能、注意、语言能力维度得分分别为（5.43±1.17）、（2.33±1.95）、（1.80±1.52）、（1.66±1.20）、（4.54±1.71）、（4.09±1.64）分。与看电视时长为>0且≤2 h/d的研究对象相比，不看电视者各个维度认知功能得分均较低，记忆力、视空功能、执行功能、注意力、语言能力、定向力维度及总体的OR（95%CI）值分别为0.68(0.48~0.96)、0.67(0.47~0.96)、0.48(0.34~0.67)、0.56(0.41~0.77)、0.45(0.33~0.62)、0.52(0.37~0.73)、0.50(0.35~0.71)；看电视时长为>2且≤4 h/d的研究对象执行功能、注意力、语言能力、定向力维度及总体得分较高，OR（95%CI）值分别为1.20(1.02~1.41)、1.41(1.19~1.67)、1.51(1.28~1.77)、1.33(1.08~1.64)、1.24(1.05~1.47)。 结论：厦门市60岁及以上老年人中看电视时长为>2且≤4 h/d者认知功能较好。.
