Item Anticipated pain as a predictor of discomfort with intrauterine device placement(Elsevier, 2018-02) Dina, Blair; Peipert, Leah; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineBackground Intrauterine devices have been gaining popularity for the past 2 decades. Current data report that >10% of women who use contraception are using an intrauterine device. With <1% failure rates, the intrauterine device is one of the most effective forms of long-acting reversible contraception, yet evidence shows that fear of pain during intrauterine device placement deters women from choosing an intrauterine device as their contraceptive method. Objectives The objective of this analysis was to estimate the association between anticipated pain with intrauterine device placement and experienced pain. We also assessed other factors associated with increased discomfort during intrauterine device placement. We hypothesized that patients with higher levels of anticipated pain would report a higher level of discomfort during placement. Study Design We performed a secondary analysis of the Contraceptive CHOICE Project. There were 9256 patients enrolled in Contraceptive CHOICE Project from the St. Louis region from 2007–2011; data for 1149 subjects who came for their first placement of either the original 52-mg levonorgestrel intrauterine system or the copper intrauterine device were analyzed in this study. Patients were asked to report their anticipated pain before intrauterine device placement and experienced pain during placement on a 10-point visual analog scale. We assessed the association of anticipated pain, patient demographics, reproductive characteristics, and intrauterine device type with experienced pain with intrauterine device placement. Results The mean age of Contraceptive CHOICE Project participants in this subanalysis was 26 years. Of these 1149 study subjects, 44% were black, and 53% were of low socioeconomic status. The median expected pain score was 5 for both the levonorgestrel intrauterine system and the copper intrauterine device; the median experienced pain score was 5 for the levonorgestrel intrauterine system and 4 for the copper intrauterine device. After we controlled for parity, history of dysmenorrhea, and type of intrauterine device, higher anticipated pain was associated with increased experienced pain (adjusted relative risk for 1 unit increase in anticipated pain, 1.19; 95% confidence interval, 1.14–1.25). Nulliparity, history of dysmenorrhea, and the hormonal intrauterine device (compared with copper) also were associated with increased pain with intrauterine device placement. Conclusion High levels of anticipated pain correlated with high levels of experienced pain during intrauterine device placement. Nulliparity and a history of dysmenorrhea were also associated with greater discomfort during placement. This information may help guide and treat patients as they consider intrauterine device placement. Future research should focus on interventions to reduce preprocedural anxiety and anticipated pain to potentially decrease discomfort with intrauterine device placement.Item Condom use and incident sexually transmitted infection after initiation of long-acting reversible contraception(Elsevier, 2017-12) McNicholas, Colleen P.; Klugman, Jessica B.; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineBackground Use of more effective contraception may lead to less condom use and increased incidence of sexually transmitted infection. Objective The objective of this study was to compare changes in condom use and incidence of sexually transmitted infection acquisition among new initiators of long-acting reversible contraceptives to those initiating non-long-acting reversible contraceptive methods. Study Design This is a secondary analysis of the Contraceptive CHOICE Project. We included 2 sample populations of 12-month continuous contraceptive users. The first included users with complete condom data (baseline, and 3, 6, and 12 months) (long-acting reversible contraceptive users: N = 2371; other methods: N = 575). The second included users with 12-month sexually transmitted infection data (long-acting reversible contraceptive users: N = 2102; other methods: N = 592). Self-reported condom use was assessed at baseline and at 3, 6, and 12 months following enrollment. Changes in condom use and incident sexually transmitted infection rates were compared using χ2 tests. Risk factors for sexually transmitted infection acquisition were identified using multivariable logistic regression. Results Few participants in either group reported consistent condom use across all survey time points and with all partners (long-acting reversible contraceptive users: 5.2%; other methods: 11.3%; P < .001). There was no difference in change of condom use at 3, 6, and 12 months compared to baseline condom use regardless of method type (P = .65). A total of 94 incident sexually transmitted infections were documented, with long-acting reversible contraceptive users accounting for a higher proportion (3.9% vs 2.0%; P = .03). Initiation of a long-acting reversible contraceptive method was associated with increased sexually transmitted infection incidence (odds ratio, 2.0; 95% confidence ratio, 1.07–3.72). Conclusion Long-acting reversible contraceptive initiators reported lower rates of consistent condom use, but did not demonstrate a change in condom use when compared to preinitiation behaviors. Long-acting reversible contraceptive users were more likely to acquire a sexually transmitted infection in the 12 months following initiation.Item Contraception and Ectopic Pregnancy Risk: A Prospective Observational Analysis(Elsevier, 2021-02) Schultheis, Paige; Montoya, Melissa Natalie; Zhao, Qiuhong; Archer, Johanna; Madden, Tessa; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineItem Contraceptive Preference, Continuation Rates, and Unintended Pregnancies in Patients with Comorbidities: A Prospective Cohort Study(Mary Ann Liebert, 2021) Leroy-Melamed, Maayan; Zhao, Qiuhong; Belmonte, Michael A.; Archer, Johanna; Peipert, Jeffrey F.; Pediatrics, School of MedicineBackground: Patients with comorbidities are more susceptible to adverse pregnancy outcomes, morbidity, and mortality than healthy patients. The goal of this study was to evaluate how comorbidities influence contraceptive choice, continuation rates, and the unintended pregnancy rate in reproductive-age participants. Methods: We analyzed data from the Contraceptive CHOICE Project. Baseline data included demographic, reproductive, and medical history, including self-reported hypertension (HTN), venous thromboembolism (VTE), migraines, cerebrovascular accidents (CVA), transient ischemic attack (TIA), or stroke. Participants were provided contraceptive counseling and their method of choice at no cost. Results: Among 9253 participants included in our analysis, 659 participants reported a history of HTN (7%), 20 participants reported a history of CVA/TIA/stroke (<1%), 1803 participants reported a history of migraine (19%), and 85 reported a history of VTE (<1%). Compared to baseline, use of long-acting reversible contraceptive methods (long-acting reversible contraception [LARC]: intrauterine devices and implants) increased for participants with all comorbidities: HTN 2.3%–84.2%; CVA/TIA/stroke 0%–85%; migraines 1.7%–77%, and VTE 1.2%–88.2%. Participants with HTN, VTE, and migraines were more likely to choose LARC than those without those conditions: HTN: relative risk (RR) = 1.14, 95% confidence interval (CI) 1.10–1.18; migraines RR = 1.04, 95% CI 1.01–1.07; and VTE RR = 1.18, 95% CI 1.09–1.28. Twelve-month continuation and unintended pregnancy rates did not differ significantly based on comorbidity status. Conclusions: Participants with serious comorbidities were more likely to choose LARC than healthy participants. Contraceptive counseling should always be individualized to the patient.Item Dual method use among long-acting reversible contraceptive users(Taylor & Francis, 2018-04) Bernard, Caitlin; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineOBJECTIVE: To compare rates of dual method use (concurrent use of condoms and an effective method of contraception) in long-acting reversible contraceptive (LARC) and non-LARC hormonal contraceptive users, and to determine factors associated with dual method use. METHODS: We conducted a secondary analysis of the Contraceptive CHOICE Project, an observational, prospective cohort study of 9256 women in St. Louis, MO, USA. Our sample included 6744 women who initiated a contraceptive method within 3 months of enrollment, continued use at 6 months post-enrollment, and responded regarding dual method use. Our primary outcome was the rate of dual method use at 6 months post-enrollment. RESULTS: Dual method use was reported by 32% of LARC and 45% of non-LARC hormonal contraceptive users (p < .01). After adjusting for other covariates and comparing to non-LARC hormonal contraceptive users, LARC users were less likely to report dual method use (RRadj 0.76, 95% CI 0.70-0.83). Factors associated with dual method use in our multivariable analysis were age <25 years, black race, lower education, single relationship status, baseline dual method use, baseline diagnosis of sexually transmitted infection (STI), greater partner willingness to use a condom, and higher condom self-efficacy score. CONCLUSIONS: LARC users are less likely to report dual method use compared to non-LARC hormonal contraceptive users, but other factors also impact dual method use. Further studies should be performed to determine whether this lower dual method use increases the risk of STI.Item Effect of Baseline Menstrual Bleeding Pattern on Copper Intrauterine Device Continuation(Elsevier, 2018) Hobby, James H.; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineBackground Heavy menstrual bleeding is a leading cause of copper intrauterine device (IUD) discontinuation. Thus, women with heavy baseline menstrual bleeding may be at increased risk for early copper IUD discontinuation. Our objective was to assess if there was an association between baseline menstrual bleeding pattern prior to IUD insertion and discontinuation rate at 12 months among study participants who chose copper IUD at baseline. Study Design We performed a secondary analysis of the Contraceptive CHOICE Project, a prospective observational cohort study of 9,256 women offered no cost contraception for 2-3 years. Included in our study were participants who chose copper IUD for contraception and for whom method continuation data at 12 months were available. Prior to contraception initiation, participants were asked to qualify their menstrual bleeding over the past year as: light, moderate, moderately heavy or heavy. Light bleeding corresponded to using 10 or fewer pads/tampons per period. Moderate, moderately heavy and heavy bleeding corresponded to 11-20 pads/tampons, 21-30 pads/tampons, and more than 30 pads/tampons per period, respectively. Subjects were then categorized into either a “heavy” baseline group (those reporting moderately heavy or heavy bleeding at baseline), or a “not heavy” group (those reporting light or moderate bleeding). The 12-month continuation rate for each group was then calculated using Kaplan-Meier survival function, and hazard ratio for risk of discontinuation was evaluated using a Cox proportional hazard model to determine if moderately heavy or heavy bleeding at baseline was associated with early discontinuation. Results Of the 918 women meeting the inclusion criteria for this analysis, 165 were in the heavy baseline bleeding group, while 753 were in the not heavy bleeding group. The 12-month continuation rates for groups were similar: 80.2% (heavy) and 85.0% (not heavy; P=0.24). Patients reporting either moderately heavy or heavy baseline bleeding were not at increased risk for early discontinuation of copper IUD (hazard ratio 1.21, 95% CI 0.88, 1.66). Our sample size provided greater than 90% power to detect a clinically important difference of 15% (assuming 20% discontinuation rate in not heavy bleeding group and a 35% discontinuation rate in the heavy bleeding group). Conclusions We did not find that women who reported baseline moderately heavy or heavy menstrual bleeding were at increased risk for early discontinuation. Thus, we do not believe that women with heavy menstrual bleeding should be discouraged from using this safe and highly-effective form of contraception.Item Intrauterine device use, sexually transmitted infections, and fertility: a prospective cohort study(Elsevier, 2021-08) Peipert, Jeffrey F.; Zhao, Qiuhong; Schreiber, Courtney; Teal, Stephanie; Turok, David K.; Natavio, Melissa; Cordon, Sabrina; Daggy, Joanne; Obstetrics and Gynecology, School of MedicineBackground In the 1970s, numerous medical reports, media coverage, and litigation around the Dalkon Shield intrauterine device led to a perception that all intrauterine devices cause upper genital tract infection and infertility. Objective This study aimed to assess the association between intrauterine device use and time to conception. Study Design The Fertility After Contraceptive Termination Study is a multicenter, prospective cohort study of women stopping their contraceptive method to attempt conception. We recruited participants between 2011 and 2017. Participants were a convenience sample of women recruited from academic centers in Philadelphia, PA; Los Angeles, CA; St. Louis, MO; Indianapolis, IN; Aurora, CO; and Salt Lake City, UT. Women were eligible if they stopped their contraceptive method within the past 120 days before enrollment, were between 18 and 35 years of age, had no history of infertility or sterilization, and had at least 6 months of follow-up. Baseline data included demographic and reproductive characteristics, past contraceptive use, nucleic acid amplification testing for sexually transmitted infections, and serology for past infection with Chlamydia trachomatis, Trichomonas vaginalis, and Mycoplasma genitalium. The primary exposure was intrauterine device use (ever); the primary outcome was time to conception. All participants were observed longitudinally for up to 24 months. We used piecewise exponential proportional hazards models with multiple imputation to provide hazard ratios and their respective 95% confidence intervals. Results Of the 461 participants, mean age was 28.2 years, 178 (38.7%) were Black, 157 (34.1%) were considered as low socioeconomic status, and 275 (59.7%) had a history of intrauterine device use. Without adjusting for any covariates, the median time to conception was shorter for participants who had a history of intrauterine device use (5.1 months) than participants who never used an intrauterine device (7.5 months). After controlling for potential confounders, the association of past intrauterine device use with time to conception was not statistically significant (adjusted hazard ratio, 1.25; 95% confidence interval, 0.99–1.58). In our multivariable model, age, nulligravidity, Black race, low socioeconomic status, and past Mycoplasma genitalium infection were associated with longer times to conception (hazard ratio, 0.76; 95% confidence interval, 0.58–0.99). Conception by 12 months was lower in participants with past Mycoplasma genitalium infection (68% vs 80% without past infection; P=.019). Conclusion We found no impairment of fertility with ever use of an intrauterine device. Serologic evidence of past Mycoplasma genitalium infection was associated with longer times to conception and higher rates of infertility. Mycoplasma genitalium infection is a potential modifiable cause of infertility.Item Knowledge and Intention to Use Long-Acting Reversible Contraception among University Students(Taylor & Francis, 2022-06-23) Asdell, Stephanie M.; Bennett, Rachel D.; Cordon, Sabrina A.; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of MedicineObjective: To assess the relationship between knowledge of long-acting reversible contraception (LARC) and intention to use LARC among female students. Participants: Participants consisted of a convenience sample of 292 female undergraduate and graduate students at a large midwestern university. Methods: We conducted a cross-sectional in-person survey and multivariate analysis of LARC knowledge and intention to use LARC. Results: Total response rate was 84.9%. Among contraceptive users, 13.3% were using a LARC method. On average, respondents scored 4.8/10 (SD 2.5) on a 10-item LARC knowledge assessment. Higher levels of LARC knowledge were associated with the intent to use LARC in the future in our multivariate analysis (RR 1.7, 95% CI 1.14-2.54: p = .01). Common reasons for LARC hesitancy were a need for more information, safety concerns, and risk of undesirable side effects. Conclusions: Low LARC knowledge and students' self-identified need for further LARC information represent an opportunity for campus contraceptive interventions which empower students to make informed reproductive decisions.Item Long-Acting Reversible Contraception (LARC) Knowledge and Intent to Use among IUPUI Students(2019-08) Asdell, Stephanie M.; Bennett, Rachel D.; Cordon, Sabrina A.; Zhao, Qiuhong; Peipert, Jeffrey F.BACKGROUND AND HYPOTHESIS: More than 50% of births to women in their early 20s are unintended, and unintended pregnancies have adverse consequences on students’ education. Long-acting reversible contraceptives (LARC), including hormonal and copper intrauterine devices (IUDs) and the contraceptive implant, offer highly-effective, long-term prevention of pregnancy, yet are utilized at low rates. Thus, we sought to assess students’ LARC knowledge and intent to use LARC at Indiana University-Purdue University in Indianapolis (IUPUI) to inform a campus family planning initiative. We hypothesized that students with higher levels of LARC knowledge are more likely to intend to use LARC in the future. We also hypothesized that a lower proportion of students utilize LARC compared to the US rate of 15.8% of all contraceptive users in 2017. EXPERIMENTAL DESIGN AND PROJECT METHODS: We designed a cross-sectional survey for undergraduates, graduate students, and resident physicians assessing sexual experiences, contraceptive use, LARC knowledge, and intent to use LARC. We summarized participants’ characteristics using descriptive statistics, compared awareness of LARC methods using McNemar’s test, and evaluated association between LARC knowledge and future intent to use a LARC method using Fisher exact. RESULTS: Thus far, we have recruited 126 participants with a response rate of 88.7%. Mean score on the 10-question LARC assessment was 5.2/10; higher levels of LARC knowledge were positively associated with future intent to use LARC (P < 0.05). Only 7.9% of contraceptive users surveyed used LARC, compared to 15.8% of US contraceptive users in 2017. Differences in awareness of the copper IUD (61.1%), hormonal IUD (74.6%) and implant (88.9%) were statistically significant (P < 0.05). The most common reason cited for not considering LARC use was “need for more information.” CONCLUSION AND POTENTIAL IMPACT: Low LARC knowledge and use and high desire for LARC education further supports need for a campus contraceptive initiative that will empower students to make informed reproductive decisions.Item Long-acting reversible contraception knowledge & intent to use among US university students.(European Society of Contraception and Reproductive Health, 2020-03) Asdell, Stephanie; Bennett, Rachel; Cordon, Sabrina; Zhao, Qiuhong; Peipert, JeffreyOBJECTIVES: More than 50% of births to women in the United States in their early 20s are unintended, and unintended pregnancies have adverse consequences on students’ education.Long-acting reversible contraceptives (LARC) offer highly-effective, long-term prevention of pregnancy, yet are utilized at low rates. Thus, we sought to assess the level of students’ LARC knowledge and any association with intent to use LARC at a large, urban university in the Midwest United States. We hypothesized that students with higher levels of LARC knowledge would be more likely to intend to use LARC in the future. We also hypothesized that fewer students would use LARC compared to the US rate of 15.8% of all contraceptive users in 2017. Data on student knowledge and attitudes regarding LARC will be used to inform a campus LARC initiative. METHODS: We designed and administered a cross-sectional survey to 300 undergraduates, graduate students, and resident physicians that assessed sexual experiences, contraceptive use, LARC knowledge, and intent to use LARC. The survey was administered at the university’s student center and student health facility in Indianapolis, Indiana. Participants’ demographic characteristics and LARC knowledge were summarized using descriptive statistics. Awareness of different LARC methods was assessed using McNemar’s test. The association between students’ reported LARC knowledge and future intent to use a LARC method was calculated with Fisher’s exact test. RESULTS: Our preliminary analysis includes 126 students. The mean age was 20.2 years. Mean score on the 10-question LARC assessment was 5.2/10. Higher levels of LARC knowledge were positively associated with future intent to use LARC (P < 0.05). Only 7.9% of contraceptive users surveyed used LARC, compared to 15.8% of US contraceptive users in 2017. Differences in awareness of the copper IUD (61.1%), hormonal IUD (74.6%) and implant (88.9%) were statistically significant (P < 0.05). The most common reason cited for not considering LARC use was “need for more information.” Conclusions: University students surveyed displayed low LARC knowledge, low LARC use, and a need for more information on LARC. A positive association between LARC knowledge and future intent to use LARC amongst students at this university further supports need for a campus-wide contraceptive initiative that will empower students to make informed reproductive decisions. Understanding student use and knowledge of LARC could also provide a model for starting other university LARC initiatives across the United States, at which uptake of LARC has been historically low.
