| 目的 分析上海市≥50岁居民的膳食模式，并探究其与认知功能的关联。方法 本研究使用WHO全球老龄化与成人健康研究中国项目上海地区第二轮调查数据，以因子分析法提取居民膳食模式，从词语回忆、语言流畅度、数字测试等方面评价个体认知功能，采用多重线性回归模型分析不同膳食模式与个体认知功能的关系。结果 本研究共纳入膳食数据完整并进行了认知功能测试的个体4 132人，从中提取3种膳食模式：植物性模式、高动物食物模式、高油盐模式。调整性别、年龄、受教育年限等因素后，植物性模式（β=0.26，95%CI：0.17~0.36）、高动物食物模式（β=0.18，95%CI：0.06~0.29）与认知功能测试总分正相关，高油盐模式（β=-0.28，95%CI：-0.85~-0.07）与语言流畅度测试得分负相关。结论 多摄入植物性食物，适量摄入动物性食物的饮食模式可能与≥50岁居民更好的认知功能有关。 |

| 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. |
