■睡眠与精神疾病有关。然而,他们的因果关系仍然未知。
■该研究探索了七个睡眠参数之间的因果关系(睡眠持续时间,失眠,睡眠呼吸暂停,时间型,白天打瞌睡,白天打盹,和打鼾)和三种精神疾病,包括重度抑郁症(MDD),精神分裂症,和注意缺陷/多动障碍(ADHD)使用两个样本孟德尔随机(MR)。睡眠参数的全基因组关联研究(GWAS)汇总数据来自英国生物银行,FinnGen生物银行,和EBI数据库。MR-Egger,加权中位数,逆方差加权(IVW),简单模式,加权模式,最大似然,惩罚加权中位数,和IVW(固定效应)用于进行MR分析。异质性由Cochran的Q统计量检测。通过MREgger检测水平多效性。通过留一法分析研究了灵敏度。
■失眠(OR=2.02,95CI=1.34-3.03,p=0.001,错误发现率(FDR)校正的p值=0.011)和白天午睡(OR=1.81,95CI=1.34-2.44,FDR校正的p值<0.001)与MDD风险增加相关。较长的睡眠时间(OR=2.20,95CI=1.24-3.90,FDR校正的p值=0.049)与精神分裂症的风险增加有关,而白天打瞌睡(OR=4.44,95CI=1.20~16.41,校正p值=0.088)和白天打盹(OR=2.11,95CI=1.11~4.02,FDR校正p值=0.088)与精神分裂症风险增加有暗示性关联.睡眠时间延长与ADHD风险降低有暗示性关联(OR=0.66,95CI=0.42-0.93,FDR校正p值=0.088)。
■这项研究为睡眠和精神疾病之间的复杂关系提供了进一步的证据。我们的发现强调了解决睡眠问题在预防精神疾病方面的潜在益处。
UNASSIGNED: Sleep is associated with psychiatric disorders. However, their causality remains unknown.
UNASSIGNED: The study explored the causal relationship between seven sleep parameters (sleep duration, insomnia, sleep apnea, chronotype, daytime dozing, napping during the day, and snoring) and three psychiatric disorders including major depressive disorder (MDD), schizophrenia, and attention-deficit/hyperactivity disorder (ADHD) using two-sample Mendelian randomization (MR). Genome-wide association study (GWAS) summary data for sleep parameters were obtained from the United Kingdom biobank, FinnGen biobank, and EBI databases. MR-Egger, weighted median, inverse-variance weighted (IVW), simple mode, weighted mode, maximum likelihood, penalized weighted median, and IVW(fixed effects) were used to perform the MR analysis. The heterogeneity was detected by Cochran\'s Q statistic. The horizontal pleiotropy was detected by MR Egger. The sensitivity was investigated by the leave-one-out analysis.
UNASSIGNED: Insomnia (OR = 2.02, 95%CI = 1.34-3.03, p = 0.001, False-discovery rate (FDR) corrected p-value = 0.011) and napping during the day (OR = 1.81, 95%CI = 1.34-2.44, FDR corrected p-value<0.001) were associated with an increased risk of MDD. Longer sleep duration (OR = 2.20, 95%CI = 1.24-3.90, FDR corrected p-value = 0.049) had an association with the increased risk of schizophrenia, while daytime dozing (OR = 4.44, 95%CI = 1.20-16.41, corrected p-value = 0.088)and napping during the day (OR = 2.11, 95%CI = 1.11-4.02, FDR corrected p-value = 0.088) had a suggestive association with an increased risk of schizophrenia. Longer sleep duration had a suggestive association with a decreased risk of ADHD (OR = 0.66, 95%CI = 0.42-0.93, FDR corrected p-value = 0.088).
UNASSIGNED: This study provides further evidence for a complex relationship between sleep and psychiatric disorders. Our findings highlight the potential benefits of addressing sleep problems in the prevention of psychiatric disorders.
