我们评估了新的含铜宫内节育器(Cu IUD)使用者在使用最初六个月期间出血、痛经以及对宫内节育器满意度的变化,并评估了出血和痛经对方法满意度的影响。 我们为这项前瞻性纵向观察队列研究招募了77名年龄在18 - 45岁的女性。符合条件的女性月经规律,在过去三个月内未使用激素避孕方法,并且希望使用含铜宫内节育器进行避孕。我们在宫内节育器置入后的180天内前瞻性地收集数据。参与者每月使用经验证的图片式失血评估表(PBAC)报告出血评分,使用五点李克特量表报告对宫内节育器的满意度,使用六级顺序量表报告痛经情况。我们使用多重填补法来处理非随机失访问题。针对计数和有序结果的结构方程模型被用于对六个月重复评估期间的出血、痛经和宫内节育器满意度增长曲线进行建模。 在研究过程中,出血情况显著减少(约23%),从置入后一个月估计的PBAC = 195降至六个月时的PBAC = 151(t = -2.38,p < 0.05)。此外,对宫内节育器的满意度随时间提高(t = 2.65,p < 0.01),在六个月的研究期间从“中立”和“满意”之间提高到“满意”。痛经在六个月的研究期间显著减少,从每两周一次到每周一次减少到每月一次或两次(t = -4.38,p < 0.001)。最后,在整个研究期间(t = -2.31,p < 0.05)以及研究结束时(t = -2.81,p < 0.01),出血而非痛经与对宫内节育器的满意度相关。 新的含铜宫内节育器使用者在最初六个月报告出血和痛经减少,对宫内节育器的满意度提高。方法满意度与出血呈负相关。
We assess change in bleeding, cramping, and IUD satisfaction among new copper (Cu) IUD users during the first six months of use, and evaluate the impact of bleeding and cramping on method satisfaction. We recruited 77 women ages 18–45 for this prospective longitudinal observational cohort study. Eligible women reported regular menses, had no exposure to hormonal contraception in the last three months, and desired a Cu IUD for contraception. We collected data prospectively for 180 days following IUD insertion. Monthly, participants reported bleeding scores using the validated pictorial blood loss assessment chart (PBAC), IUD satisfaction using a five-point Likert scale, and cramping using a six-level ordinal scale. We used multiple imputation to address nonrandom attrition. Structural equation models for count and ordered outcomes were used to model bleeding, cramping, and IUD satisfaction growth curves over the six monthly repeated assessments. Bleeding significantly decreased (approximately 23%) over the course of the study from an estimated PBAC = 195 at one month post-insertion to PBAC = 151 at six months (t = -2.38, p<0.05). Additionally, IUD satisfaction improved over time (t = 2.65, p<0.01), increasing from between “Neutral” and “Satisfied” to “Satisfied” over the six month study. Cramping decreased notably over the six month study from between biweekly and weekly, to once or twice a month (t = -4.38, p<0.001). Finally, bleeding, but not cramping, was associated with IUD satisfaction across the study (t = -2.31, p<0.05) and at study end (t = -2.81, p<0.01). New Cu IUD users reported decreasing bleeding and cramping, and increasing IUD satisfaction, over the first six months. Method satisfaction was negatively associated with bleeding.
