Retrospective investigation and analysis of sleep disorders on occurrence of polycystic ovary syndrome

Objective: To investigate the sleep status before polycystic ovary syndrome (PCOS) and analyze the relationship between sleeping and PCOS.

Study design: A retrospective cohort study recruited 129 PCOS patients and 156 non-PCOS infertility women according to Rotterdam criteria. All patients filled in Pittsburgh Sleep Quality Index (PSQI).

Results: According toPSQI scoring PCOS patients had a significant sleeping quality score (1.24 ± 0.72) than non-PCOS group (0.99 ± 0.71) (P=0.004). The sleeping time score, sleeping disorder score, daytime dysfunction, total score of PSQI and sleep disorders judgment for PCOS group were 0.71 ± 0.72, 1.09 ± 0.49, 1.58 ± 0.77, 6.82 ± 2.61 and 69.77% respectively. There were statistically differences between PCOS group and non-PCOS group. Age and sleep efficiency were identified as protective factors for PCOS, but sleeping disorders, day time dysfunction and snoring were high risk factors for PCOS.

Conclusion: Poor sleeping is possible risk for PCOS.
