In the study, 19-year-olds born in 1962, 1972 and 1982 were asked questions about their height, weight, pregnancies, children, period pain and contraception. The latest results, published in the leading journal
, reveal that women who use a copper IUD do not suffer from worse period pain than women who use other non-hormonal contraceptives (such as condoms) or no contraception at all, while women who use a hormonal IUD or the combined pill and those who have given birth experience milder period pain.
"Research into period pain is sorely needed," says researcher Ingela Lindh from the Sahlgrenska Academy, University of Gothenburg. "Lowering the number of women who suffer from period pain will bring down absence from work and school and reduce the consumption of painkillers."
Lindh says the new study provides new and valuable information about when an IUD should be considered, for both medical professionals and users:
"Women often have incorrect information about how different forms of contraception affect period pain."
