目的探讨膳食硒与不良睡眠模式之间的关系。方法利用2007—2014年美国健康和营养检查调查（NHANES）的数据，采用加权多因素logistic回归和限制性立方样条，根据BMI、饮酒等协变量进行分层分析和交互作用分析，研究膳食硒与不良睡眠模式（睡眠困难、睡眠障碍、睡眠时间）之间的关系。结果加权多因素logistic回归表明，每日膳食硒的摄入量在Q2组（78.33～105.6μg/L）对睡眠模式有保护作用。限制性立方样条分析表明在膳食硒与睡眠时间之间发现了U形曲线的关系，亚组分析发现，BMI为25～29.9 kg/m2的研究对象膳食硒摄入量和不良睡眠模式之间有良好的相关性。结论在普通人群中，每日膳食硒摄入量在78.3～105.6μg/L范围内可能会降低不良睡眠模式的风险，且仅在超重的研究者中发现膳食硒的摄入量与不良睡眠模式存在负相关。
