Background:
Dysmenorrhea negatively affects daily functioning; however, its association with restorative sleep remains undetermined, while sleep-related health is a recent topic. This study investigated whether there is an association between dysmenorrhea severity and the absence of restorative sleep in women.
Methods:
This cross-sectional study included 2,752 women of 18-56 years of age who underwent health-screening. Dysmenorrhea was categorized as mild, moderate, or severe, based on self-reports. Restorative sleep was evaluated using a questionnaire regarding sufficient rest from sleep. Their associations were tested using a logistic regression analysis adjusted for confounders with odds ratio (OR) and 95% confidence interval (CI).
Results:
Restorative sleep was absent in 38.4% of this population. There was a significant association between severe dysmenorrhea and the absence of restorative sleep (adjusted OR 2.282, 95% CI 1.744-2.986; P < 0.001). There was also a significant association between moderate dysmenorrhea and the absence of restorative sleep (adjusted OR 1.241, 95% CI 1.049-1.467; P = 0.012).
Conclusions:
The results indicated a positive association between dysmenorrhea severity and the absence of restorative sleep in women. The evaluation of restorative sleep may be relevant to health checks in association with dysmenorrhea.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
