摘要Background and Aims: Specific diets or lifestyles have an impact on cognitive function in previous studies.However, the association of the complex action of Chinese daily diets and lifestyle patterns with mild cognitive impairment (MCI) among elderly people had not been studied exactly.The aim of this study was to explore the association of dietary and lifestyle patterns with MCI among elderly people in Beijing.Methods: A population-based and case-control design was utilized in this study.Atotal of 404 subjects, aged 60 years old or above, living in Beijing were enrolled.The Montreal cognitive assessment (MoCA) was used to screen the subjects with MCI.All subjects were required to complete a questionnaire which was comprised of their demographic information, health status, lifestyles, andfood frequency questionnaire (FFQ).Multivariable logistic regression analysis was used to evaluate the potential association between MCI and these factors.Results: With adjustment for some factors , higher daily intake of eggs (OR, 0.975, 95% CI, 0.959-0.992, P=.003) and marine products (OR, 0.961, 95% CI, 0.943-0.979, P=.000), longer time of watching TV (OR, 0.763, 95% CI, 0.628-0.928, P=.007) and reading (OR, 0.540, 95% CI, 0.379-0.769, P=.001) physical exercise (OR, 0.382, 95% CI, 0.185-0.789) had significantly decreased odds of suffering from MCI compared withthe controlgroup.Conclusions: Our findings suggested that daily higher intake of eggs and marine products, watching TV, reading and physical exercise prevent the development of MCI in this population-based samples.
