Sexually Transmitted Infection Prevention With Long-Acting Reversible Contraception: Factors Associated With Dual Use

Association between relationship characteristics, sexual health attitudes, and dual contraceptive use among young adult college students aged 18-24

Objective Determine the relationship characteristics, sexual health attitudes, and demographic factors associated with dual contraceptive use among college students. Participants: September-October 2018 via campus email, we recruited College of Public Health students attending a large, urban, public university (N = 424). Methods: Respondents completed a cross-sectional, Web-based sexual health questionnaire. Descriptive statistics were calculated. Multiple logistic regression models were run to determine the association between relationship characteristics, pregnancy and condom attitudes, demographics, and dual use the last time having sex. Results: In independent models, one-unit increase in trust (aOR = 0.982; 95% CI: 0.966-0.998) and commitment score (aOR = 0.987, 95% CI: 0.976-0.999) was inversely associated with dual use while sex with a casual date/acquaintance (aOR = 3.149; 95% CI: 1.550-6.397) was positively associated. In a fully adjusted model for all correlates, only trust score was significant (aOR = 0.982; 95% CI: 0.966, 0.998). Conclusions: Emotion-based constructs may be more influential on dual use behaviors than discrete relationship factors.

Identifying gaps in dual protection from sexually transmissible infections and unintended pregnancies among Australian women: an observational study

Background Dual protection refers to the simultaneous prevention of sexually transmissible infection (STI) and unintended pregnancies. Optimal contraception and STI prevention strategies sometimes fail to align. Methods Using data from a large nationally representative population-based survey, we analysed the contraception and STI prevention behaviours at the last vaginal intercourse among 2420 heterosexually active women aged 16-34years who had participated in the Second Australian Study of Health and Relationships, 2012-13. Results At their last vaginal intercourse, most women (95%) used contraception and half (49%) used condoms, either as a sole multipurpose method or in conjunction with another type of contraception. Condom use was highest (72%) among women whose most recent partner was a casual or occasional partner, followed by women with a regular partner (59%) and women with a cohabiting regular partner (40%). One-third of the women (34%) used condoms as a sole method, and 14% used oral contraceptives together with a condom. Few women used implants or intrauterine devices (8%) and, among them, very few women also used condoms (<1%). Among the women who used a condom at their last vaginal intercourse, 49% reported both the correct use for STI prevention and consistent condom use during the previous 6months. Among women using condoms, correct and consistent use was also highest among women whose most recent partner was a casual or occasional partner (76%). Conclusions Although almost all women used contraception and half used dual protection, few benefited from the protective effects of using condoms together with highly effective contraception.

Long-Acting Reversible Contraceptive Users' Knowledge, Conversations with Healthcare Providers, and Condom Use: Findings from a U.S. Nationally Representative Probability Survey

Objectives To describe long-acting reversible contraceptive (LARC) users' knowledge, patient-provider interactions, and condom use associated with LARC use. Methods: Data are from the 2018 National Survey of Sexual Health and Behavior, a probability survey of Americans aged 14-49. Results: Of 1,451 sexually active women, 11.2% used intrauterine devices, and 3.1% used implants. Approximately 19-26% of LARC users reported inaccurately on LARC longevity, and 30% reported relying on their provider to indicate the timing of intrauterine device removal. Consistent condom use among LARC users was rare (6.1%). Conclusions: Our findings have implications for how clinicians educate patients on LARC and condom use.

Condom use among young women in Australia using long-acting reversible contraceptives or other hormonal contraceptives

Background Dual condom and long-acting reversible contraceptive (LARC) or non-LARC hormonal contraceptive use is the most effective way to protect against unwanted pregnancy and sexually transmissible infections (STIs). This study aimed to determine whether condom use varied between users of LARC and non-LARC hormonal contraceptives and explore their motivations for condom use.

METHODS

Women aged 16-24 years attending a sexual and reproductive health centre in Melbourne, Australia, completed a survey about contraceptives and sexual practices. The proportion of LARC and non-LARC hormonal contraceptive users using condoms was calculated and logistic regression compared condom use between the two groups. Condom use was based on frequency of use and coded as a binary variable 'never, not usually or sometimes' versus 'usually or always'.

RESULTS

In all, 294 (97%) women participated in the study; 23.8% (95% confidence interval (CI) 19.0-29.1%) used LARC and 41.7% (95% CI 36.0-47.6%) used non-LARC hormonal contraceptives. Condom use was reported by 26.1% (95% CI 16.3-38.1%) of LARC users and by 27.8% (95% CI 19.9-37.0%) of non-LARC hormonal contraceptive users. There was no difference in condom use between groups (odds ratio (OR) 0.9; 95% CI 0.4-1.9). Condom use reduced with increasing relationship length (≥6 months vs no relationship: OR 0.2; 95% CI 0.1-0.6). Non-LARC hormonal contraceptive users were more motivated to use condoms if worried about pregnancy than LARC users (62.8% vs 47.8%; P = 0.04).

CONCLUSION

Condom use was low and similar between users of LARC and non-LARC hormonal contraceptives, and was associated with the length of the relationship. These results highlight the need to promote condom use when prescribing LARCs and non-LARC hormonal contraceptives to reduce the risk of STIs.

Young Women's Complex Patterns of Contraceptive Use: Findings from an Australian Cohort Study

CONTEXT

Unintended pregnancy is common among young women. Understanding how such women use contraceptives- including method combinations-is essential to providing high-quality contraceptive care.

METHODS

Data were from a representative cohort of 2,965 Australian women aged 18-23 who participated in the 2012-2013 Contraceptive Use, Pregnancy Intention and Decisions baseline survey, had been heterosexually active in the previous six months, and were not pregnant or trying to conceive. Latent class analysis was employed to characterize women's contraceptive choices; multinomial logistic regression was used to evaluate correlates of membership in the identified classes.

RESULTS

The vast majority of women (96%) reported using one or more contraceptives, most commonly short-acting hormonal methods (60%), barrier methods (38%), long-acting contraceptives (16%) and withdrawal (15%). In total, 32 combinations were reported. Four latent classes of method use were identified: no contraception (4% of women); short-acting hormonal methods with supplementation (59%, mostly the pill); high-efficacy contraceptives with supplementation (15%, all long-acting reversible contraceptive users); and low-efficacy contraceptive combinations (21%); supplementation usually involved barrier methods or withdrawal. Class membership differed according to women's characteristics; for example, women who had ever been pregnant were more likely than other women to be in the no-contraception, high-efficacy contraceptive or low-efficacy contraceptive combination classes than in the short-acting hormonal contraceptive class (odds ratios, 2.0-3.0).

CONCLUSIONS

The complexity of women's contraceptive choices and the associations between latent classes and such characteristics as pregnancy history highlight the need for individualized approaches to pregnancy prevention and contraceptive care.

Dual-Method Contraception Among Adolescents and Young People: Are Long-Acting Reversible Contraception Users Different? A Qualitative Study

STUDY OBJECTIVE

The purpose of this study was to understand the factors and influences that affect dual-method contraception in adolescent and young adult women using long-acting reversible contraception (LARC) and whether these are unique to LARC users.

DESIGN

Qualitative semistructured interview study.

SETTING AND PARTICIPANTS

Adolescents and young women aged 14-24 years using LARC methods, adolescents and young women aged 14-24 years using short-acting reversible contraception (SARC), and men aged 14-30 years.

INTERVENTIONS

Interviews were conducted until thematic saturation was reached.

MAIN OUTCOME MEASURES

The team used a grounded theory approach to identify common themes relating to dual-method contraception.

RESULTS

Interviews were conducted with 20 LARC users, 26 SARC users, and 13 men. There were no differences in dual-method contraception use between LARC users and SARC users. Most participants used condoms primarily for pregnancy prevention rather than sexually transmitted infection (STI) prevention. Relationship context played an important role in dual-method contraception among all 3 groups; participants were less likely to use condoms in a long-term or monogamous relationship than with new or casual partners. Most participants perceived themselves to be at low risk for STI acquisition, although even those who identified themselves to be at risk did not consistently use condoms. Immediate availability of condoms was a determinant of condom use in all 3 groups, whereas knowledge, access, and negotiation of condom use were not.

CONCLUSION

LARC users are similar to SARC users in their decision-making about condom use. Relationship factors and STI risk assessment are important components to be included in contraceptive counseling.

Is Long-Acting Reversible Contraceptive Use Increasing? Assessing Trends Among U.S. College Women, 2008-2013

Objective To assess LARC use trends among college women (18-24 years) and identify groups that have increased LARC use. Methods Data were extracted from the National College Health Assessment-II (NCHA-II) fall 2008-2013 surveys. Logistic regression statistics were used to assess LARC use. Results Although LARC use increased from 2008 to 2013 (aOR = 2.62; 95% CI 2.23-3.07), less than half of the sample (44%) reported using contraception at last vaginal sex. Only 2.5% of college women in this study reported using a LARC method; of LARC users, 90% reported using an intrauterine device. Nearly all sociodemographic factors were significantly associated with increases in LARC use including: age, sexual orientation, and insurance status. Conclusions LARC use significantly increased among college women. However, less effective methods such as condoms and short-acting reversible contraceptives are used more frequently. Promoting LARC use for women who desire to effectively prevent pregnancy can reduce unintended pregnancy and improve health outcomes for women while in college. Future work should examine the importance of individual and lifestyle factors that influence college women's decision to choose a LARC method and seek to eliminate barriers to college women choosing a contraceptive method they believe works best for them.

Dual method use among long-acting reversible contraceptive users

OBJECTIVE

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 (RR_adj 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.
