中文摘要: 目的 通过孟德尔随机化(MR)分析睡眠时长和儿童注意缺陷多动障碍(ADHD)发病风险之间的因果关系。方法 从全基因组关联研究数据库下载睡眠时长数据集(ukb-b-4424)以及ADHD数据集(ieu-a-1183),筛选出48个单核苷酸多态性(SNPs)作为工具变量(Ivs)。分别使用逆方差加权法(IVW)、加权中位数法(WME)、MR-Egger回归、加权模式和简单模式方法检验睡眠时长与ADHD患病风险之间的MR分析,以风险值(OR)评估睡眠时长与ADHD发病风险的因果关联。同时运用留一法进行敏感性分析,MR-Egger截距检验水平多效性,随机效应模型检测异质性。结果 IVW分析结果显示睡眠时长与ADHD发病风险存在负相关(OR=0.597,95%CI:0.376~0.948,P=0.028)。敏感性分析结果稳定,MR-Egger截距检验无水平多效性,随机效应模型检测不存在异质性。结论 随着睡眠时长的增加,ADHD发病风险随之减低。
Abstract:Objective To investigate the causal relationship between sleep duration and the risk of attention deficit hyperactivity disorder(ADHD)in children using Mendelian randomization(MR). Methods Genome-wide association study(GWAS)datasets for sleep duration(ukb-b-4424)and ADHD(ieu-a-1183)were downloaded,and 48 single nucleotide polymorphisms(SNPs)were selected as instrumental variables(IVs). The causal association between sleep duration and ADHD risk was assessed using inverse-variance weighted(IVW),weighted median estimator(WME), MR-Egger regression,weighted mode,and simple mode methods,with odds ratio(OR)used to estimate the effect. Sensitivity analysis was conducted using the leave-one-out method,while horizontal pleiotropy was evaluated using the MR-Egger intercept test,and heterogeneity was assessed using a random-effects model.Results IVW analysis revealed a negative correlation between sleep duration and ADHD risk( OR=0.597,95%CI:0.376-0.948,P=0.028). Sensitivity analysis confirmed stable results,and the MR-Egger intercept test indicated no significant horizontal pleiotropy. The random-effects model showed no heterogeneity. Conclusion Increased sleep duration is associated with a reduced risk of ADHD.
