人们对饮食模式对睡眠问题的影响的关注有限。在本研究中，我们分析了中国嘉道理生物银行 481,242 名 30-79 岁成年人的横断面数据。进行了基于笔记本电脑的问卷调查，以收集有关食物摄入量和失眠症状的信息。使用逻辑回归根据每种饮食模式的四分位数来估计每种失眠症状的优势比，并调整潜在的混杂因素。通过因子分析得出两种主要的饮食模式。北方传统饮食模式的特点是大量摄入小麦等主食，而现代饮食模式的特点是大量摄入肉、禽、鱼、蛋、新鲜水果和乳制品。两种饮食模式均与失眠症状发生率降低相关（趋势 p < 0.001）；调整潜在的混杂因素后，北方传统饮食模式得分最高四分位的个体出现失眠症状的可能性比最低四分位的个体低12%-19%（优势比：0.81-0.88），而现代饮食模式的相应值为0.89-1.01。此外，还观察到这两种饮食模式对失眠症状的相互作用。需要进一步的前瞻性研究来阐明饮食与失眠之间的关系。
Limited attention has been paid to the effect of dietary patterns on sleep problems. In the present study, we analyzed the cross-sectional data of 481,242 adults aged 30-79 years from the China Kadoorie Biobank. A laptop-based questionnaire was administered to collect information on food intakes and insomnia symptoms. Logistic regression was used to estimate the odds ratios of each insomnia symptom according to quartiles of each dietary pattern, with adjustment for potential confounders. Two major dietary patterns were derived by factor analysis. The traditional northern dietary pattern was characterized by high intakes of wheat and other staple food, whereas the modern dietary pattern was characterized by high intakes of meat, poultry, fish, eggs, fresh fruit, and dairy products. Both dietary patterns were associated with a decreased prevalence of insomnia symptoms (p for trend < 0.001); after adjustment for potential confounders, individuals who had the highest quartile score of traditional northern dietary pattern were 12%-19% less likely to have insomnia symptoms compared to those in the lowest quartile (odds ratio: 0.81-0.88), and the corresponding values for the modern dietary pattern were 0.89-1.01. Furthermore, interactions of these two dietary patterns on insomnia symptoms were observed. Further prospective studies are needed to elucidate the relationship between diet and insomnia.
