Abstract:
Objective:To explore the cognitive functions of the elderly aged 60 years and above in Xiamen, and whether TV watching time would affect those functions.
Methods:We conducted a cross-sectional study on 3 230 registered individuals aged 60 years and above in Xiamen from July to October in 2016 with a multi-stage random sampling method. Montreal Cognitive Assessment (MoCA) was used to measure cognitive functions and ordinal logistic regression was used to quantify their associations with TV watching time.
Results:A total of 2 944 respondents were included in this study. The overall age of them was (70.14±7.81) years. 51.49% (n=1 516) of all participants were men. Overall, the mean scores of MoCA in general and each subdomain cognitive function were 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), and 4.09±1.64 (language). Compared to those who watched TV no more than 2 hours per day, the elderly who did not watch TV had a worse performance in general, orientation, memory, visuospatial, executive, attention, language function, with 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) and 0.45 (0.33-0.62), respectively. As to respondents who watched TV more than 2 hours but no more than 4 hours per day, they had a better performance in general, executive, attention, language, and orientation function with respective OR (95%CI) values about 1.24 (1.05-1.47), 1.20 (1.02-1.41), 1.41 (1.19-1.67), 1.51 (1.28-1.77) and 1.33 (1.08-1.64).
Conclusion:The elderly aged 60 years and above in Xiamen City with TV watching time between 2 and 4 hours per day had a good performance in cognitive functions compared to those with more or less TV watching time.
