To assess clinical performance, bleeding pattern, dysmenorrhea, and satisfaction up to 1 year after placement of 3 types of intrauterine devices (IUDs) (TCu380A, levonorgestrel 52 mg, and levonorgestrel 19.5 mg) in adolescents The study was a randomized trial with 318 adolescents allocated to the 3 IUDs. We assessed reasons for removal, continuation, menstrual patterns, dysmenorrhea, and satisfaction. Participants aged (mean ± SD) 17.9 ± 1.4 years, with 80.8% being nulligravidae. After 1 year, 265 (83.3%) continued using the IUD; however, the continuation rate of TCu380A (75.4 ± 4.2) was lower than that of both the levonorgestrel 52-mg (88.6 ± 3.1) and 19.5-mg IUDs (86.8 ± 3.3), and bleeding/pain and expulsion were the main reasons for removal of the TCu380A IUD. The duration of menstruation was longer among the TCu380A IUD users (6.0 ± 2.0 days) than those using the levonorgestrel 52 mg (2.5 ± 3.9) and 19.5 mg (3.2 ± 3.2) devices, P <.001. Amenorrhea was reported by 49.5% and 37.8% users of the levonorgestrel 52-mg and 19.5-mg devices, respectively, P <.001. Dysmenorrhea was reported in 68.5% of all participants at the baseline; this was 67.9% of the TCu380A group and 33.3% and 36.0% of the levonorgestrel 52-mg and 19.5-mg IUD groups, respectively, P <.001. Satisfaction ranged from 80.7% in the TCu380A group to 97.8% in the levonorgestrel 52-mg group (P =.03). The 3 IUDs are suitable for adolescents, with high contraceptive efficacies and rates of continuation within 1 year of use and high degrees of satisfaction. Users of the hormonal IUDs reported lower expulsion rates, more favorable menstrual patterns, and less dysmenorrhea compared with the TCu380A IUD. [ABSTRACT FROM AUTHOR]

To compare pain and ease of insertion of the copper 380 mm2, levonorgestrel 52 mg, and levonorgestrel 19.5-mg intrauterine devices (IUDs) in Brazilian adolescents. We conducted a participant-blinded randomized trial at two clinics in Brazil. We enrolled 318 adolescents<19 years old in a 1:1:1 ratio from November 2021 to February 2022. We informed the adolescents about the IUD type inserted after they evaluated the pain associated with the IUD insertion using a Visual Analogue Scale and immediately after that the healthcare provider who placed the IUD evaluated the ease of the procedure. The VAS pain level was significantly higher after the levonorgestrel 52-mg IUD placement, median and [interquartile range, IQ] 8.0 [4.0] than the copper 380-mm2 IUD 7.0 [4.0], and the levonorgestrel 19.5-mg IUD 7.0 [6.0] (p = 0.001). The placement was easier after the copper 380-mm2 IUD (87/106, 82.1%) and the levonorgestrel 19.5-mg IUD (91/106, 85.8%) when compared with the levonorgestrel 52-mg IUD (75/105, 70.7%). After multiple logistic regression analyses, the higher VAS pain scores were associated with the levonorgestrel 52-mg IUD (OR = 2.90), low number of pregnancies (OR –0.48), and with a history of dysmenorrhea (OR = 2.67). The placement of the copper 380-mm2 IUD and the levonorgestrel 19.5-mg IUD was associated with lower pain according to the adolescent and was easier according to the provider when compared with the levonorgestrel 52-mg IUD. However, the small observed differences may not be clinically relevant. We found that the three types of IUDs were generally easy to place; however, mean pain scores were high during insertions. Our findings of high pain scores reinforce the need for interventions to reduce pain for adolescent IUD insertion. [ABSTRACT FROM AUTHOR]
