There is considerable evidence supporting the elevated risk of mental health problems in individuals with evening chronotype relative to those with morning or intermediate chronotypes. Recent data, however, suggest that this risk may be explained, at least partially, by poor sleep quality.
This study aimed to further clarify the roles of chronotype and sleep quality in mental health outcomes (depression, anxiety, stress) in young individuals (18-40 years) living in the UK (n = 185) or Germany (n = 209).
Consistent with our recent observations in a comparable North Indian sample, we found that poor quality of sleep had significantly positive associations with adverse mental health outcomes both in the UK and Germany-based samples. Significant associations between evening chronotype and poor mental health were also evident, but these associations were fully mediated by poor quality of sleep in both samples.
These observations suggest that efforts to identify sleep disruption in a timely manner and promotion of good sleep may prevent mental health problems, especially in individuals with evening chronotype and other known risks for mental disorders.
有大量证据支持，与早晨型或中间型昼夜节律类型的个体相比，夜晚型昼夜节律类型的个体出现心理健康问题的风险更高。然而，最近的数据表明，这种风险至少部分可能是由睡眠质量差造成的。
本研究旨在进一步阐明昼夜节律类型和睡眠质量在居住在英国（n = 185）或德国（n = 209）的18至40岁年轻人心理健康结局（抑郁、焦虑、压力）中的作用。
与我们最近在一个可比的北印度样本中的观察结果一致，我们发现，在英国和德国的样本中，睡眠质量差与不良心理健康结局均存在显著的正相关。夜晚型昼夜节律类型与不良心理健康之间也存在显著关联，但在两个样本中，这些关联均完全由睡眠质量差介导。
这些观察结果表明，及时识别睡眠障碍并促进良好睡眠的措施可能预防心理健康问题，尤其是在夜晚型昼夜节律类型的个体以及其他已知有精神障碍风险的个体中。
