Dual method use among a sample of first-year college women

A systematic review of the association between history of sexually transmitted infections and subsequent condom use in adolescents

Sexually transmitted infections (STIs) are common among adolescents. According to the Health Belief Model, cues to action influence preventive behaviors. Cues to action can include health experiences such as being diagnosed with an STI. The impact of a history of STIs on subsequent condom use among adolescents remains largely unexamined, despite high rates of recurrence and their health impacts. This project aimed to systematically review the literature on the association between curable STIs and subsequent condom use among adolescents. The systematic review, reported following PRISMA guidelines, was conducted using the Joanna Briggs Institute method. Eligible studies, in the form of cohort studies, case-control studies, or cross-sectional studies, targeted adolescents aged 10 to 24, with or without a history of curable STIs; the outcome was subsequent condom use. MEDLINE (Ovid), Embase (Elsevier), and Web of Science were searched from January 2012 to December 2022 with the assistance of an information specialist. Two reviewers independently selected articles and extracted data. Risk of bias analysis was performed using ROBINS-E. The review explores results, with tables, based on population characteristics, exposure, and outcome, and addresses the influence of gender, ethnicity, and age. Of 3088 articles identified, seven studies were retained. Almost all the studies focused on African-American, Nigerian, or Rwandan adolescents, and several included only girls. Among girls, a history of STI increased subsequent condom use in combination with other contraceptive methods (n = 4). Among boys and older adolescents of both genders, a history of STI was associated with a decrease in condom use (n = 3). No study distinguished between different STIs. While all the studies (n = 7) presented a high risk of bias, six did not present a threat to conclusion validity. All the studies indicated that a history of STI could influence subsequent protective behaviors, possibly by acting as a cue to action, as posited by the Health Belief Model. This information enhances our understanding of factors leading to the adoption of preventive health measures among adolescents and could apply to other infectious experiences.Registration The protocol is registered in PROSPERO (CRD42023397443).

The Association Between Nonbarrier Contraceptive Use and Condom Use Among Sexually Active Latina Adolescents

PURPOSE

This study aimed to determine the association between use of highly effective methods of nonbarrier contraception and condom use in a sample of Latina adolescents and whether the change to a more effective method of nonbarrier contraception is associated with a change in condom use.

METHODS

As part of a larger study, 442 sexually active Latina adolescents aged 14-18 years were surveyed immediately before an appointment with a medical care provider at a school-based health center and 3 months later. Ordinal logistic and linear regression were used in the analysis of cross-sectional and longitudinal data to assess the relationship between patterns of nonbarrier contraception and condom use.

RESULTS

The use of all types of nonbarrier methods of contraception was significantly associated with decreased condom use. Change over time from a less effective to a more effective nonbarrier method of contraception was also associated with a decrease in condom use. Greater number of sexual encounters was associated with lower the frequency of condom use.

CONCLUSIONS

The use of highly effective methods of nonbarrier contraception was associated with reduced frequency of condom use. This highlights the need to promote condom use concurrently with nonbarrier methods of contraception to improve protection against both pregnancy and STIs.

Catching up! The sexual behaviour and opinions of Italian students (2000–2017)

While sexuality has radically changed across middle–high-income societies in recent years, only outdated studies are available for Italy. We aim to provide novel insights into the sexual behaviour and opinions of young Italians diachronically and through a gendered lens. Our analysis compares the results of two national samples of university students collected in 2000 and 2017. The sexual behaviour and opinions of young men and women seem to be converging in several respects. We observed a feminisation of male opinions and behaviour within couples, which is to say that men are more likely to experience first intercourse with a young woman of roughly the same age while in a stable relationship, and betray—or accept betrayal—with less frequency and willingness than in the past. Similarly, we found a masculinisation of female opinions and behaviour outside of stable relationships, for example, an increase in occasional partners, a net drop in the expectation that other women hold virgin status before marriage, and a doubling of the acceptance of casual sex. A few gender differences remain, especially concerning sexual double standards: young men and women are still subject to diverse rules guiding their sexual behaviour. Finally, acceptance of homosexuality has risen substantially—particularly among women.

Sexual Behavior Patterns and Condom Use in Newly Sexually Active Female University Students

Our objective was to describe sexual behavior patterns and condom use in newly sexually active female university students. We conducted a 4-year retrospective cohort study (2000-2007) of university women enrolled close to sexual debut (N = 250). Participants reported daily information on intercourse, condom use, and partner/partnership characteristics into Web-based biweekly sexual behavior diaries. We calculated intercourse frequency, proportion of condom-protected events, and incidence of new partner acquisition. We used logistic regression to examine factors associated with condom use at sexual debut; Kaplan-Meier methods to describe cumulative incidence of condom non-use after use at debut; and Cox proportional hazards ratios to examine factors associated with condom non-use. A total of 188 women had at least one male sex partner prior to enrollment or during follow-up. One-third (34.1%) of 27,736 intercourse events were condom-protected. Older age (20+ vs. < 20 years) and use of hormonal birth control were associated with lower likelihood of condom use at sexual debut (adjusted odds ratio [aOR] 0.41, 95% CI 0.17-0.97 and aOR 0.32, 95% CI 0.10-1.03, respectively). Women who reported partners with previous sex partners were less likely to discontinue using condoms after debut (hazard ratio = 0.35, 0.16-0.77) than those reporting partners without previous partners. In college-aged women, older age and hormonal contraceptive use were each inversely associated with condom use at first intercourse. Women with sexually experienced partners were more likely to continue using condoms. Continued efforts are necessary to promote condom use among college-aged women.

Trends in long-acting reversible contraceptive (LARC) use, LARC use predictors, and dual-method use among a national sample of college women

OBJECTIVE

Assess long-acting reversible contraceptive (LARC) and other contraceptive use trends, identify LARC use predictors, and examine dual method use.

PARTICIPANTS

Women in the American College Health Association-National College Health Assessment (ACHA-NCHA) II, aged 18-24 years, who reported having vaginal sex (N = 37,899).

METHODS

Secondary analyses of Fall 2011-2014 ACHA-NCHA II data.

RESULTS

Statistically significant increases in LARC usage and, specifically, implant usage, were found. Characteristics associated with LARC use included age, race/ethnicity, relationship status, and school type. Students reporting LARC use had lower odds of condom usage compared with non-LARC hormonal method users.

CONCLUSION

This analysis of LARC predictors and dual LARC/condom use has implications for research and health promotion efforts. Findings suggest that college health services are well positioned to meet the sexual and reproductive health needs of diverse populations of students. College health professionals should elicit students' individual and/or relationship priorities to tailor messaging/services offered for pregnancy/STI prevention.

Effects of initiating a contraceptive implant on subsequent condom use: A randomized controlled trial

OBJECTIVE

To evaluate whether initiation of a contraceptive implant, a method of long-acting reversible contraception, reduces condom use, as measured by a biomarker of recent semen exposure [prostate-specific antigen (PSA)].

STUDY DESIGN

We conducted a randomized controlled clinical trial in which 414 Jamaican women at high risk for sexually transmitted infections (STIs) attending family planning clinics received the contraceptive implant at baseline ("immediate" insertion arm, N=208) or at the end ("delayed" insertion arm, N=206) of a 3-month study period. Participants were tested for PSA at baseline and two follow-up study visits and were asked about their sexual activity and condom use.

RESULTS

At baseline, 24.9% of women tested positive for PSA. At both follow-up visits, the prevalence of PSA detection did not significantly differ between the immediate versus delayed insertion arm [1-month: 26.1% vs. 20.2%, prevalence ratio (PR)=1.3, 95% confidence interval (CI)=0.9-1.9; 3-month: 25.6% vs. 23.1%, PR= 1.1, 95% CI=0.8-1.6]. The change in PSA positivity over the three study visits was not significantly larger in the immediate arm compared to the delayed arm (1-sided p-value of .15).

CONCLUSIONS

Contraceptive implants can be successfully introduced into a population at high risk of unintended pregnancy and STIs without a biologically detectable difference in unprotected sex in the short term. This information strengthens the evidence to support promotion of implants in such populations and can help refine counseling for promoting and maintaining use of condoms among women who choose to use implants.

IMPLICATIONS

Sex unprotected by a condom was not higher over 3 months in women receiving a contraceptive implant, compared with those not receiving the implant.
