Contraceptive knowledge among women at risk of unintended pregnancy in Kingston, Jamaica.

Low contraceptive knowledge may limit contraception initiation or continuation and, consequently, could represent an important, modifiable cause of unintended pregnancy. The objective of this analysis was to identify correlates of knowledge among women at risk of unintended pregnancy. We analyzed data from a study of 222 young women attending a public clinic in Kingston in November 2018 to March 2019. We measured contraceptive knowledge with seven questions on method reversibility, ability to use covertly, contraindications, and side effects. We used multivariable linear regression to evaluate the correlates of summary knowledge scores and report beta coefficients, which represent differences in mean summary knowledge scores. The mean knowledge score was low (2.7; range = 0-7). Only 30.2% of the participants correctly identified intrauterine devices as more effective than oral contraception, male condoms, and withdrawal. Women who reported that their provider discussed contraception scored higher (adjusted ß = 0.37, p = 0.05) than those not reporting this. Women who perceived implants as very/mostly safe scored higher (adjusted ß = 0.45, p = 0.01) than those perceiving the device as mostly/very unsafe. Finally, compared to contraception non-users, women using less-effective contraception had a lower score (adjusted ß = -0.40, p = 0.04) while those using effective contraception did not differ in scores (ß = -0.30, p = 0.18). Overall, we found poor contraceptive knowledge among young women in Kingston. Providers appeared to hold an important role in women's understanding of contraception.

Prevalence and risk factors associated with STIs among women initiating contraceptive implants in Kingston, Jamaica.

BACKGROUND: There is limited information on rates of STIs in Jamaica due to syndromic management and limited aetiological surveillance. We examined the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) and characteristics associated with STIs among sexually active women who participated in a randomised trial of a progestin implant initiation in Jamaica (the Sino-Implant Study (SIS)). METHODS: SIS was a randomised trial conducted in Kingston, Jamaica, from 2012 to 2014 to evaluate whether initiation of the Sino-Implant (II) led to more unprotected sex among women ages 18-44 years. Data collected included self-reported demographic, sexual behaviour information; and vaginal swabs collected at baseline, 1-month and 3-month follow-up visits for a biomarker of recent semen exposure (prostate-specific antigen (PSA)) and for STIs. We examined associations between STIs and PSA, demographics, sexual behaviour and insertion of an implant, with a repeated-measures analysis using generalised estimating equations (SAS Institute, V.9.3). RESULTS: Remnant vaginal swabs from 254 of 414 study participants were tested for STIs. At baseline, 29% of participants tested for STIs (n=247) had laboratory-confirmed CT, 5% NG, 23% TV and 45% any STI. In a repeated-measures analysis adjusted for study arm (immediate vs delayed implant insertion), those with PSA detected did not have an increased prevalence of any STI (prevalence ratio (PR)=1.04 (95% CI 0.89 to 1.21)), whereas prevalence decreased for each 1-year increase in age (PR=0.98 (95% CI 0.97 to 0.99)). Immediate implant insertion was not associated with increases in any STI in subsequent visits (PR=1.09 (95% CI 0.94 to 1.27)). CONCLUSIONS: Although the prevalence of laboratory-confirmed STIs was high, the immediate initiation of a contraceptive implant was not associated with higher STI prevalence rates over 3 months. TRIAL REGISTRATION NUMBER: NCT01684358.

Sexual Relationship Power and Semen Exposure Among Female Patients at a Sexually Transmitted Infection Clinic in Kingston, Jamaica.

Women's power in sexual relationships is thought to be an important predictor of condom use. However, research on correlates of condom use often relies on participant reporting of behavior, which has questionable validity. We evaluated the association between scores from the modified Sexual Relationship Power Scale (SRPS-M) and biological detection of semen exposure in a prospective study of adult women attending a sexually transmitted infection clinic in Kingston, Jamaica with cervicitis or abnormal vaginal discharge in 2010-2011. At enrollment, women were counseled to avoid sex while on treatment and were asked to return in 6 days for a follow-up visit. At both study visits, women were administered a questionnaire and had vaginal swabs collected to test for prostate-specific antigen (PSA), a biological marker of recent semen exposure. We found no significant association at enrollment or follow-up between SRPS-M scores and semen exposure, as measured with either self-reported data or PSA positivity. Semen biomarkers could be used to develop and validate new scales on relationship power and self-efficacy related to condom use.

Differences in misreporting of sexual behavior over time: implications for HIV trials.

We used data from a prospective study of 300 women attending a sexually transmitted infection clinic in Kingston, Jamaica, to compare participant self-report of recent semen exposure to actual semen exposure measured by prostate-specific antigen in vaginal swabs. Underreporting of semen exposure was significantly more frequent at follow-up than baseline, suggesting that the accuracy of reports of sexual behavior may vary over time.

Randomized controlled trial on the effectiveness of counseling messages for avoiding unprotected sexual intercourse during sexually transmitted infection and reproductive tract infection treatment among female sexually transmitted infection clinic patients.

BACKGROUND: The effectiveness of counseling messages to avoid unprotected sex during short-term treatment for curable sexually transmitted infections is unknown. METHODS: We randomized 300 female STI clinic patients 18 years or older with cervicitis and/or vaginal discharge in Kingston, Jamaica, in 2010 to 2011, to 1 of 2 counseling messages for their course of syndromic treatment: abstinence only or abstinence backed up by condom use. At a follow-up visit 6 days afterward, we collected vaginal swabs to test for prostate-specific antigen (PSA), a biological marker of recent semen exposure, and administered a questionnaire assessing sexual behavior. RESULTS: No differences were found in the proportions of women testing positive for PSA at follow-up in the abstinence-plus-condom group (11.9%) and abstinence-only group (8.4%) (risk difference, 3.5; 95% confidence interval, -3.5 to 10.5). There also was no significant difference in reporting of unprotected sex between groups. Reporting a history of condom use before enrollment significantly modified the effect of counseling arm on PSA positivity (P = 0.03). Among those reporting recent condom use, 10.3% in the abstinence-only arm and 4.8% in the abstinence-plus-condom arm tested positive for PSA. Conversely, among those not reporting recent condom use, 6.5% in the abstinence-only arm and 17.3% in the abstinence-plus-condom arm had PSA detected. CONCLUSIONS: We found no evidence to support the superiority of either counseling message. Post hoc analyses suggest that women with recent condom experience may benefit significantly more from abstinence-plus-condom messages, whereas women without such experience may benefit significantly more from abstinence-only messages. Providers should weigh individual condom use history when determining the most appropriate counseling message.

Exploring discordance between biologic and self-reported measures of semen exposure: a qualitative study among female patients attending an STI clinic in Jamaica.

We explored the use of qualitative interviews to discuss discrepancies between two sources of information on unprotected sex: biomarker results and self-reported survey data. The study context was a randomized trial in Kingston, Jamaica examining the effect of STI counseling messages on recent sexual behavior using prostate-specific antigen (PSA) as the primary study outcome. Twenty women were interviewed. Eleven participants were selected because they tested positive for PSA indicating recent semen exposure, yet reported no unprotected sex in a quantitative survey ("discordant"): 5 reported abstinence and 6 reported condom use. Nine participants who also tested positive for PSA but reported unprotected sex in the survey were interviewed for comparison ("concordant"). Qualitative interviews with 6 of the 11 discordant participants provided possible explanations for their PSA test results, and 5 of those were prompted by direct discussion of those results. Rapid PSA testing combined with qualitative interviews provides a novel tool for investigating and complementing self-reported sexual behavior.

Debunking myths about contraceptive safety among women in Kingston, Jamaica: Pilot randomized controlled trial.

OBJECTIVES: (1) To create a short motion graphic video to debias women, using evidence from cognitive psychology, of 2 common myths about safety of intrauterine devices (IUDs) and implants in Jamaica; and (2) to conduct a pilot study to evaluate video effectiveness. STUDY DESIGN: We conducted a series of 3 focus group discussions among target users to inform the development process of the script, story, character, and look of the intervention video. We randomized young, female nonusers of long-acting contraception at risk of pregnancy at a public clinic in Kingston in 2018-2019 to watch either the intervention (n = 113) or control video (n = 112). We used logistical regression to evaluate perceptions of method safety, naturalness, and uptake after 3 months of follow up. RESULTS: Almost all (n = 220; 97.8%) participants completed the 3-month interview. More women in the intervention arm perceived IUDs to be safe (59.1%) compared to the control arm (43.6%; p = 0.02). Perceived implant safety increased from enrollment to follow up in the intervention and control arms (10.9 and 2.7 percentage-point increases, respectively); however, the difference between arms at follow up was not statistically significant (p = 0.57). This appeared to be due to arm imbalances at enrollment. Study arms did not differ at follow up in perceived IUD naturalness (p = 0.36) or implant naturalness (p = 0.68). CONCLUSIONS: Findings from a pilot study of a video intervention suggest that using debiasing strategies from cognitive psychology has the potential to address misconceptions about contraceptive safety. A larger trial with adequate power is warranted. IMPLICATIONS: Evidence from a pilot randomized controlled trial suggested that use of debiasing strategies from cognitive psychology could be effective in correcting women's misconceptions about contraception safety and thus show promise for the design of future contraceptive promotion videos to increase uptake.

The performance of a syndromic algorithm in diagnosing cervicitis in Jamaica.

A cross-sectional survey of 295 persons attending a major sexually transmitted infection clinic in Jamaica's capital city showed that the Ministry of Health's syndromic algorithm has moderate sensitivity and negative predictive value for diagnosing cervicitis. In the absence of diagnostic tests for sexually transmitted infections, a syndromic algorithm continues to be useful for diagnosing sexually transmitted infections.

Hormonal contraception and the risks of STI acquisition: results of a feasibility study to plan a future randomized trial.

BACKGROUND: Because of limitations in observational studies, a randomized controlled trial (RCT) would help clarify whether hormonal contraception increases the risks of acquiring a sexually transmitted infection (STI). However, the feasibility of such a trial is uncertain. STUDY DESIGN: We conducted a study to assess the feasibility of conducting a RCT that would compare the acquisition risk for Chlamydia trachomatis and Neisseria gonorrhoeae in women randomized to an intrauterine device (IUD) or depot medroxyprogesterone acetate (DMPA). In our cross-sectional survey conducted at three clinics, we gave information on a potential RCT to clients, asked them questions to assess comprehensibility and finally asked respondents whether they would consider enrolling in such a trial. In addition, the 190 participants provided urine or endocervical swab specimens so we could estimate the prevalence of STIs. RESULTS: Overall, 70% of participants stated that they would take part in a future trial and accept randomization to either the IUD or DMPA. Participant understanding of the trial requirements was high. Twenty-nine percent of the participants were infected with either N. gonorrhoeae or C. trachomatis. CONCLUSION: With a high prevalence of STI in this population and the apparent willingness of appropriate candidates to participate, an RCT to measure risks of incident STI infection from hormonal contraception appears feasible.

Assessing prevalence of missed laboratory-confirmed sexually transmitted infections among women in Kingston, Jamaica: results from a secondary analysis of the Sino-Implant clinical trial.

OBJECTIVES: To assess potentially missed sexually transmitted infections (STIs), we compared clinically diagnosed STIs to laboratory-confirmed diagnoses of gonorrhoea (GC), chlamydia (CT) and trichomonas (Tvag). DESIGN: Secondary analysis of a randomised controlled trial. SETTING: We used data and specimens previously collected for the Sino-Implant Study in Kingston, Jamaica. PARTICIPANTS: The Sino-Implant Study randomised 414 women to receive a levonorgestrel implant at either baseline or 3 months post-enrolment to evaluate unprotected sex after implant initiation. This analysis used 254 available vaginal swab samples. OUTCOME MEASURES: Clinically diagnosed STIs were determined from medical records by assessing clinical impressions and prescriptions. Laboratory-confirmed STIs included GC, CT and Tvag tested by Aptima Combo 2 for CT/GC and Aptima Tvag assays (Hologic, San Diego, California, USA). Log-binomial regression models fit with generalised estimating equations were used to estimate associations of clinically diagnosed STIs with laboratory-confirmed diagnoses and demographic and behavioural characteristics. RESULTS: Overall, 195 (76.8%) women had laboratory-confirmed STI (CT, GC or Tvag) while only 65 (25.6%) women had clinically diagnosed cervicitis and/or vaginitis during the study period. Clinical diagnosis missed 79.7% of laboratory-confirmed STIs: 85% of GC (n=17/20), 78.8% of CT (n=141/179) and 80.0% of Tvag (n=180/225). Hormonal contraceptive use in the month prior to the study visit was significantly associated with clinical diagnosis at any time point (prevalence ratio (PR): 1.65, 95% CI 1.07 to 2.54). As age increased, clinically missed infections significantly decreased (PR: 0.98 per year increase, 95% CI 0.97 to 1.00). CONCLUSIONS: The prevalence of laboratory-confirmed STIs was much higher than what was captured by clinical diagnosis. GC, CT and Tvag were not accurately detected without lab confirmation. Missed diagnoses decreased with older age. Increased laboratory capacity and refinement of the syndromic approach are needed to protect the health of sexually active Jamaican women. TRIAL REGISTRATION NUMBER: NCT01684358.

Decreased condom breakage and slippage rates after counseling men at a sexually transmitted infection clinic in Jamaica.

PURPOSE: Our objective was to evaluate condom failure (breakage and slippage) rates before and those during a trial that provided instructions on correct condom use. METHOD: Our analysis was based on 314 men who presented with urethral discharge at Jamaica's largest sexually transmitted infection clinic and were enrolled into our 6-month trial. RESULTS: Participants reported breaking 18.5% (95% confidence interval=12.8-24.1%) of their condoms during the 7 days prior to the screening visit and having 3.5% (95% confidence interval=1.2-5.7%) of their condoms slip off completely. After the condom counseling provided during the screening visit, breakage rates decreased (p<.05) and remained below 10% throughout the trial. During in-depth interviews, the men who reported frequent condom failures cited (1) improper storage/exposure to heat, (2) improper handling while putting on condoms and (3) use of lubricants/improper lubricants as the possible reasons for their high failure rates. CONCLUSION: Although the rates of reported condom breakage and slippage decreased significantly after counseling, we need to improve the quality of condom counseling to further reduce failure rates.

Association of Progestin Contraceptive Implant and Weight Gain.

OBJECTIVE: To evaluate initiation of a two-rod, 150-mg levonorgestrel contraceptive implant on women's perceived and observed body weight. METHODS: We conducted a secondary analysis of data from an open, randomized controlled trial of adult, nonpregnant, human immunodeficiency virus-negative women attending a public clinic in Kingston, Jamaica, who were assigned to initiate implant use either immediately or after a 3-month delay. The primary objective of the parent study was to assess the effect of initiation of the implant on the frequency of condom use. We compared study arms during follow-up using one-sided χ tests for differences in perceived weight gain and loss, one-sided Wilcoxon-Mann-Whitney tests for median gain in measured weight, and logistic regression with generalized estimating equations for risk of gaining greater than 2 kg. RESULTS: From 2012 to 2014, women were assigned to the implant (n=208) or delay arm (n=206). At 3 months, more women in the implant arm (15.3%) reported perceived weight gain than in the control arm (4.3%) (P=.01). Despite differences in perception, the implant and control arms did not differ significantly in median weight gain at 1-month (0.0 kg and 0.0 kg, respectively; P=.44) and 3-month visits (0.5 kg and 0.0 kg, respectively; P=.27). Study arms did not differ in risk of gaining greater than 2 kg (odds ratio 0.9, 95% confidence interval 0.6-1.3). CONCLUSION: We found no evidence of weight gain from short-term implant use. Through the power of the nocebo effect, the practice of counseling women to expect possible weight gain from initiating implant use could lead them to perceive weight gain even in its absence and contribute to the early discontinuation of this highly effective contraceptive method.

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.

HIV-1 drug resistance in treatment-naive chronically infected patients in Jamaica.

BACKGROUND: HIV-1 drug resistance in treatment-naive patients has a significant impact on the individual patient as well as implications for the wider population. These effects are amplified in the context of resource-limited settings, which are rapidly expanding access to antiretroviral therapy. METHODS: This cross-sectional survey at a single treatment site in Kingston, Jamaica was designed to identify the prevalence of HIV-1 drug-resistant mutations in chronically infected, treatment-naive patients. Mutations were identified using the Stanford HIV database algorithm and the World Health Organization (WHO) HIV Drug Resistance (HIVDR) surveillance mutations. RESULTS: The inclusion of 103 cases in the study resulted in 79 (76.6%) amplifiable samples. Genotype analysis revealed that 12.6% (95% CI 5.3, 19.9) were identified as having clinically significant mutations, while 10.1% (95% CI 3.5, 16.7) had WHO HIVDR surveillance mutations. CONCLUSIONS: According to the WHO standard, this study population has a moderate level of HIVDR in treatment-naive patients and strongly implies the need to introduce HIVDR surveillance in Jamaica.

Self-reported condom use is associated with reduced risk of chlamydia, gonorrhea, and trichomoniasis.

OBJECTIVES: To evaluate the association between self-reported condom use and prevalent and incident chlamydia, gonorrhea, and trichomoniasis. STUDY DESIGN: Prospective study of 414 males attending a sexually transmitted infection (STI) clinic in Jamaica. Condom use and STI status were assessed at enrollment and at 4 follow-up visits. RESULTS: The analyses on condom use and prevalent STI included data from 414 men, while those on incident STI were based on 1111 intervals from 355 men. We diagnosed prevalent STI (chlamydia, gonorrhea, and/or trichomoniasis) in 54.6% (n = 226) of the participants at enrollment. About 14% (n = 51) of participants had at least 1 of the study STIs during follow-up. Follow-up visits in which participants reported consistent condom use (100% of acts) for the past 7 days had less incident STI (adjusted OR, 0.4; 95% CI, 0.2-0.9) compared with visits where no condom use was reported. Self-reported condom use was more closely correlated with incident than prevalent STI. For example, the adjusted OR for prevalent infection for participants reporting consistent versus no condom use in past 7 days was 0.7 (95% CI, 0.4-1.2). Classifications based on the number of unprotected acts yielded findings similar to those based on the proportion of acts protected. CONCLUSIONS: Consistent condom use was associated with reduced risk of incident urethral STI. Research on condom effectiveness should focus on incident STI outcomes, where the temporal relationship between condom use and infection is clearer.

Does a choice of condoms impact sexually transmitted infection incidence? A randomized, controlled trial.

OBJECTIVE: The objective of this study was to assess whether providing a choice of condoms would increase condom acceptability, increase self-reported use, and decrease incident sexually transmitted infection. STUDY: We randomized 414 men presenting with urethral discharge in Jamaica to receive either the "standard" clinic condom or a choice of 4 different types of condoms. Men were treated presumptively at enrollment and followed up at 1, 2, 4, and 6 months. RESULTS: Participants in the choice group had a strong preference (P <0.01) for the most popular condom available in Jamaica. This preference did not translate into higher condom use (P = 0.16). The 6-month cumulative probability of first incidence of gonorrhea, chlamydia, or trichomoniasis was slightly higher in the choice group (21%; 95% confidence interval [CI], 15-28%) versus the control group (17%; 95% CI, 11-23%); the difference in the survival curves was not significant (P = 0.35). CONCLUSION: A choice of condoms may increase perceived acceptability but not lead to increased condom use and subsequently lower sexually transmitted infection rates.
