(1) Background: In clinical trials, dietary magnesium use can improve insomnia symptoms. However, little is known about the association between dietary magnesium consumption and sleep disorder symptoms including daytime falling asleep, sleepiness and snoring at the population level. (2) Methods: We used data from 1487 adults aged 20 and above attending the Jiangsu Nutrition Study. At baseline in 2002, dietary magnesium was assessed by 3-day weighed food records. At follow-up in 2007, sleep disorder symptoms, including daytime falling asleep, sleepiness and snoring at night, were gathered using a sleep questionnaire. (3) Results: The mean intake of magnesium was 332.5 mg/day. In total, 5.3%, 13.2% and 35.7% of the subjects reported daytime falling asleep, daytime sleepiness, and snoring during sleep, respectively. Compared with the lowest quartile of magnesium intake, the highest quartile was associated with decreased likelihood of falling asleep (odds ratio (OR) 0.12 (0.02, 0.57)) in women but not in men after adjusting for demographic, anthropometric, lifestyle factors, hypertension, and overall dietary patterns. No associations were found between dietary magnesium intake and daytime sleepiness nor night snoring in either gender. (4) Conclusions: Dietary magnesium intake may have long-term benefits in reducing the likelihood of daytime falling asleep in women.
（1）背景：在临床试验中，饮食镁的使用可以改善失眠症状。然而，对于饮食镁摄入量与包括白天嗜睡、嗜睡和夜间打鼾在内的睡眠障碍症状之间的关联，在人群水平上知之甚少。（2）方法：我们使用了参加江苏营养研究的 1487 名 20 岁及以上成年人的数据。在 2002 年的基线时，通过 3 天称重食物记录评估饮食镁。在 2007 年的随访中，使用睡眠问卷收集了睡眠障碍症状，包括白天嗜睡、白天嗜睡和夜间打鼾。（3）结果：镁的平均摄入量为 332.5 毫克/天。共有 5.3%、13.2%和 35.7%的受试者分别报告了白天嗜睡、白天嗜睡和夜间打鼾。与镁摄入量最低的四分位数相比，最高四分位数与女性白天入睡的可能性降低相关（比值比（OR）0.12（0.02，0.57）），但在调整了人口统计学、人体测量学、生活方式因素、高血压和整体饮食模式后，男性则没有。在两性中，饮食镁摄入量与白天嗜睡或夜间打鼾均无关联。（4）结论：饮食镁摄入可能对女性白天入睡的可能性降低有长期益处。
