A study on the correlation between smoking, light to moderate alcohol consumption, and cognitive function in elderly men in the community
Journal Title: Chinese Journal of Nervous and Mental Diseases - Year 2024, Vol 50, Issue 4
Abstract
[Objective] To explore the correlation between smoking, light to moderate alcohol consumption and cognitive function in elderly men in the community. [Methods] One thousand two hundred one elderly men (excluding heavy drinkers) from the Chinese longitudinal aging cohort database were selected and divided into smoking and drinking group (n=332), non-smoking but drinking group (n=126), smoking but non-drinking group (n=308), and non-smoking and non-drinking group (n=435) based on self-provided smoking and drinking information. Cognitive function was evaluated using the Beijing version of the Montreal cognitive assessment (MoCA). A two factor ANOVA and a multiple factor linear regression model were used to analyze differences in cognitive function, and risk factors for cognitive decline, respectively. [Results] The main effect analysis indicated that light to moderate alcohol consumption had a statistically significant impact on MoCA total score (F=6.076, P=0.014), MoCA naming (F=1.179, P=0.001), and MoCA abstraction (F=7.718, P=0.006). Light to moderate drinkers had lower MoCA total score (22.50±5.27 vs. 23.30±5.28), MoCA naming (2.41±0.85 vs.2.58±0.76), and MoCA abstraction (0.93±0.84 vs. 1.10±0.82) compared to non-drinkers. The main effects of smoking on MoCA total score (F=0.234, P=0.628), MoCA naming (F=0.110, P=0.741), and MoCA abstraction (F=1.335, P=0.248) were not significant. There was no interaction between smoking and light to moderate alcohol consumption on MoCA score (P>0.05). The results of multiple factor linear regression analysis showed a positive correlation (B=0.125, P=0.008) between no history of light to moderate alcohol consumption and MoCA naming. A stratified analysis of non-dementia individuals showed a positive correlation between a history of light to moderate alcohol consumption and MoCA total score (B=0.550, P=0.011) and MoCA naming (B=0.134, P=0.002). [Conclusion] Smoking and light to moderate alcohol consumption have no significant mutual effect on cognitive function in elderly men in the community, while light to moderate alcohol consumption may be associated with the impairments in global cognitive and naming functions.
