Methods: This was a descriptive cross-sectional study carried out between July 1<sup>st</sup> 2015 and June 30 2016, i.e. a duration of one year. Results: A total of 551 patients received advice on various contraceptive methods. Most of this advice was given in the post-partum period (40.2%) and during antenatal care (39.1%). Of the patients advised, 87 (15.8%) used the intrauterine device. The majority of users (93%) were married and uneducated (63.2%), and 39.1% were poor. The majority (56.3%) of intra-uterine devices were inserted in the immediate post-partum period. The majority of women had no adverse events either during the first six weeks (n = 57;65.5%) or at 3<sup>rd</sup> months (n = 75;86.2%) or 6<sup>th</sup> months (n = 76;87.4%) after IUD insertion. Most users remained complication-free throughout the follow-up period (n = 76;87.4% at 6<sup>th</sup> weeks and 3<sup>rd</sup> months, and n = 77;88.5% at 6<sup>th</sup> months). The continuation rate was 89.7% at 6 weeks and 3<sup>rd</sup> months, and 87.4% at 6<sup>th</sup> months after insertion. The majority of users (87.0%) were satisfied with the care they received. Conclusion: This study showed very few complications among intrauterine device users, and high continuation and satisfaction rates. The intrauterine device is a long-acting, effective, reversible and safe contraceptive that can be used by most women for birth spacing in Guinea, where women do not regularly visit health facilities.展开更多
