Background
The mental activity, such as reading, playing mahjong or cards and computer use, is common among older adults in China. Previous researches suggest a protective role of mental activity against cognitive impairment. However, the relationship between mental activity and all-cause mortality has rarely been reported.
Objectives
This study aims to explore the effect of mental activity on all-cause mortality in a community-based elderly cohort in China.
Methods
The current study sample comprised 4003 community residents age ≥ 60 y who were enrolled at June 2015, and were followed up every year from 2015 to 2018. Reading, playing mahjong or cards and computer use were measured by questionnaires and summed into a mental activity index (MAI) score. Cox proportional hazards analysis and Kaplan-Meier survival analysis were used to examined the effect of mental activity on all-cause mortality.
Results
During 4 y of follow-up of 4003 participants, 208 (5.2%) deaths were registered. Of all participants, 66.8%, 26.7%, 6.1% and 0.35% reported 0, 1, 2 and 3 MAI score, respectively. There was a strong association between the MAI score and all-cause mortality (adjusted hazard ratio [HR] = 0.72, 95% confidence intervals [CI]: 0.54–0.96, P = 0.025). Stratified analysis suggested that higher MAI score was significantly associated with decreased risk of all-cause mortality mainly among those who were male, aged ≥ 80 y, physical inactive, and diagnosed without cancer in past (P < 0.05).
Conclusion
Mental activity could reduce the risk for death from all cause, which help promote a comprehensive understanding of health characteristics at advanced ages.
