Interviews was used over the phone (CATI, converso) from the educated interviewers.

Whenever we provided menstrual symptoms in the regression model, the fresh new correlations remained significant, except for brand new protective effectation of hormonal birth-control play with ( Table step three ).Yet not, progestin-only strategies stayed protective within this 2nd regression design. Concurrently, outcome of so it design reveal a robust relationship anywhere between monthly period issues and PMS, having women that stated incredibly dull menses are 3 times because the likely in order to meet criteria to own PMS and you can women who said attacks long-term for longer than 1 week getting doubly browsing see criteria, even after handling for usage away from hormones birth control.
