Abstract

Background and objectives: The composition of the human diet is complex and diverse, and the relation-ship between dietary composition and cognitive decline has not been adequately studied. Therefore, this study explored the possible association between food items and the risk of cognitive impairment.

Methods and study design: This cross-sectional study was based on an ecological longevity cohort and included 2881 participants (1086 men and 1795 women) aged ≥30 years between December 2018 and November 2019. The association between food items and the risk of cognitive impairment was explored using the Bayesian kernel machine regression (BKMR) learning model.

Results: Finally, 2881 participants (1086 men and 1795 women) were included. In all participants, the multivariable logistic analysis showed that fresh fruit consumption was associated with cognitive function (OR=0.999, 95% CI: 0.998-0.999, p=0.021). Using the BKMR model, none of the 18 food items were significantly correlated with cognitive function among women. In men, when the other food items were fixed at the 25th, 50th, and 75th percentile values (P25, estimate=-0.239; P50, estimate=-0.210; P75, estimate=-0.158), there was a negative correlation between fresh fruit consumption and the predicted risk of cognitive function disorders.

Conclusions: Men displayed a negative association be-tween fresh fruit consumption and the risk of cognitive function disorders, but this was not apparent among women.

中国广西饮食复杂性与认知功能的关系:一项横断面研究

背景与目的:人类饮食构成复杂多样，饮食构成与认知能力下降之间的关系尚未得到充分研究。因此，本研究探讨了食物与认知障碍风险之间可能存在的联系。方法和研究设计:本横断面研究基于生态长寿队列，在2018年12月至2019年11月期间纳入年龄≥30岁的2881名参与者(1086名男性和1795名女性)。采用贝叶斯核机器回归(BKMR)学习模型探讨了食物与认知障碍风险之间的关系。结果:最终纳入2881名参与者(1086名男性和1795名女性)。在所有参与者中，多变量logistic分析显示新鲜水果消费与认知功能相关(OR=0.999, 95% CI: 0.998-0.999, p=0.021)。使用BKMR模型，18种食物中没有一种与女性的认知功能显著相关。在男性中，当其他食物项目固定在第25、50和75百分位值时(P25，估计=-0.239;P50估计= -0.210;P75，估计值=-0.158)，新鲜水果消费量与认知功能障碍的预测风险呈负相关。结论:男性食用新鲜水果与认知功能障碍的风险呈负相关，但这在女性中并不明显。
