Risk factors for delayed intrauterine device removal among menopausal women in rural China

Objective More women in China have received intrauterine devices (IUDs) than in the rest of the world combined. Recent reports have recognized a growing problem of delayed removal of these IUDs after menopause, especially in rural China, but few studies have examined women's knowledge and other risk factors for delayed removal. Methods A total of 1,014 perimenopausal and postmenopausal women aged 45 to 64 years participating in a pilot program providing free IUD removal in rural China completed a questionnaire. We examined their knowledge about when IUDs should be removed and other demographic and reproductive health characteristics and the association of these factors with whether their IUD removal was on time or delayed using bivariate contingency analysis and multivariate logistic regression. Results A total of 40.2% of women were having their IUDs removed more than 2 years after menopause, and 67.9% did not know the correct time for IUD removal. Women who were older, less educated, had one child, had their IUD placed in a rural facility, and with no gynecological examination in the past 2 years were less likely to know when an IUD should be removed. In multivariate analysis, knowledge, the facility where the IUD was placed, and a recent gynecological examination were independent predictors of on-time removal. At least 170 women had received a gynecological examination after menopause without the IUD being removed at that time. Conclusions Lack of knowledge about timing for IUD removal and structural barriers in health service organization must be addressed to improve care for millions of women with IUDs in rural China.
