Effect of 5-HT2A receptor polymorphisms and occupational stress on self-reported sleep quality: a cross-sectional study in Xinjiang, China

Occupational stress and 5-HTR2A genotypes in workers are associated both independently and in combination with increased risk of poor sleep quality. Our data provide evidence that occupational stress contributes to the risk of poor sleep quality through interaction with 5-HTR2A gene polymorphism.
