Working Alone, Limited Restroom Accessibility, and Poor Menstrual Health Among Cosmetics Saleswomen in South Korea.

Menstrual hygiene management (MHM) at work has been neglected in occupational health research despite its importance for female workers' health. This study investigated the association between hours of working alone and poor menstrual health among 740 cosmetics saleswomen in South Korea. Hours of working alone in a day were classified into 4 categories. MHM was measured by asking "Over the past six months, have you ever experienced that you could not change your sanitary pad when you need to change it at work?" We also measured the experience of dermatopathy due to unchanged sanitary pads. Cosmetics saleswomen who worked alone for 3 h or more in a day reported a higher prevalence of ever being unable to change the sanitary pads (prevalence ratio [PR] 1.84, 95% confidence interval [CI]: 1.37-2.46) and dermatopathy due to unchanged sanitary pads (PR 2.06, 95% CI: 1.18-3.59) than those who worked alone less than 1 h in a day.
