Abstract:
Objective: To investigate the association between dietary pattern and cognitive performance in local residents aged ≥50 years in Shanghai. Methods: Data were obtained from the second round of Study of Global Ageing and Adult Health (SAGE) survey in Shanghai. Dietary patterns were surveyed by factor analysis. Cognitive tests were conducted to assess subjects' cognitive performance, including verbal recall, verbal fluency and digit test. Multiple linear regression analysis was used to evaluate the relationship between dietary patterns and cognition performance. Results: A total of 4 132 subjects with complete dietary and cognitive performance test data were included. Factor analysis was used to obtain three dietary patterns: including plant-based pattern, high animal-food pattern, high salt-oil pattern. After controlling for gender, age, education level and other factors, it was found that plant-based pattern (β=0.26,95%CI: 0.17-0.36) and high animal-food pattern (β=0.18, 95%CI:0.06-0.29) were positively associated with total cognitive test score while high salt-oil pattern (β=-0.28, 95%CI:-0.85--0.07) was negatively associated with verbal fluency test score. Conclusion: A dietary pattern with high intake of plant food and appropriate intake of animal food might be associated with better cognitive function of residents aged ≥50 years.
