Those results reveal their working conditions were very stressful to cope as young females. 2. The use of hair dyes(OR=2.89, 95%CI:1.17-7.12), counteractive solutions(OR=3.20, 95%CI:1.04-9.83) and not wearing protective gloves(OR=2.81, 95%CI:1.11-7.12) are significantly associated with menstrual pains. 3.
