Global epidemiology of Neisseria gonorrhoeae in infertile populations: systematic review, meta-analysis and metaregression

Objective

To provide an in-depth systematic assessment of the global epidemiology of gonorrhoea infection in infertile populations.

Methods

A systematic literature review was conducted up to 29 April 2019 on international databases and WHO regional databases, and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All prevalence measures of gonorrhoea infection among infertile populations, based on primary data, qualified for inclusion. Infertile populations were broadly defined to encompass women/men undergoing infertility evaluation or treatment (infertility clinic attendees and partners). Pooled mean prevalence by relevant strata was estimated using random-effects meta-analysis. Associations with prevalence and sources of heterogeneity were explored using metaregression. Risk of bias was assessed using four quality domains.

Findings

A total of 147 gonorrhoea prevalence studies were identified from 56 countries. The pooled mean prevalence of current gonorrhoea infection was estimated globally at 2.2% (95% CI 1.3% to 3.2%), with the highest prevalence in Africa at 5.0% (95% CI 1.9% to 9.3%). The mean prevalence was higher for populations with tubal factor infertility (3.6%, 95% CI 0.9%–7.7%) and mixed cause and unexplained infertility (3.6%, 95% CI 0.0% to 11.6%) compared with other diagnoses, such as ovarian and non-tubal infertility (0.1%, 95% CI 0.0% to 0.8%), and for secondary (2.5%, 95% CI 0.2% to 6.5%) compared with primary (0.5%, 95% CI 0.0% to 1.7%) infertility. Metaregression identified evidence of variations in prevalence by region and by infertility diagnosis, higher prevalence in women than men and a small-study effect. There was a trend of declining prevalence by about 3% per year over the last four decades (OR=0.97, 95% CI 0.95 to 0.99).

Conclusions

Gonorrhoea prevalence in infertile populations is several folds higher than that in the general population, with even higher prevalence in women with tubal factor infertility and in individuals with secondary infertility. These findings support the potential role of gonorrhoea in infertility and suggest that some infertility is possibly preventable by controlling gonorrhoea transmission.

Self-report of sexually transmitted infections from 1994 to 2010 by adults living in France

BACKGROUND

Since 1994, French population-based knowledge, attitudes, beliefs and practices surveys have enabled researchers to estimate trends in sexual behavioural indicators.

METHODS

We estimated trends and prevalence of self-reported sexually transmitted infections during the previous 5 years among 16,095 sexually active adults aged 18-54 through five cross-sectional telephone surveys between 1994 and 2010. We then studied the factors associated with participants' most recent sexually transmitted infections other than genital candidiasis.

RESULTS

Overall, 2.5% (95% confidence interval: 2.2%-2.9%) of women reported sexually transmitted infections within the previous 5 years, increases being continuously reported between 1998 and 2010. In contrast, men reported lower prevalence of sexually transmitted infections (1.4%; 95% confidence interval: 1.1%-1.7%), which remained stable over time. General practitioners and gynaecologists managed most sexually transmitted infections. Men notified their stable partners about infection less often than women (66% vs. 84%). Self-reported sexually transmitted infections were associated with younger age, multiple sexual partnerships and fear of sexually transmitted infections in both genders, with exclusively homosexual practices in men, and with a high educational level and recent HIV testing in women.

CONCLUSION

Self-reported sexually transmitted infections clearly reflect risky sexual behaviours. The lower prevalence of self-reported sexually transmitted infections among men than among women may reflect less access to screening activities for sexually transmitted infections in men.

Sexual behaviours, knowledge and attitudes regarding safe sex, and prevalence of non-viral sexually transmitted infections among attendees of youth clinics in St. Petersburg, Russia

BACKGROUND

Adolescents and young adults are at increased risk of sexually transmitted infections (STIs). Knowledge of STI prevalence and risk factors are essential tools to elaborate preventive strategies. However, internationally reported studies on epidemiology of STIs among the youth in Russia are mainly lacking.

OBJECTIVES

To ascertain sexual behaviours, knowledge and attitudes about safe sex and prevalence and correlates with STIs in attendees of youth clinics in St. Petersburg, Russia.

METHODS

A total of 301 women and 131 men, who self-referred for STI testing, completed a questionnaire and were screened for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and Trichomonas vaginalis using nucleic acid amplification tests.

RESULTS

The overall STI prevalence was 16.9%, and similar in the female patients and male patients (15.6% and 19.8% respectively). C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis were detected in 13%, 2.5%, 4.6% and 1.2% of the attendees respectively. The men displayed riskier sexual behaviours and worse knowledge and attitudes regarding safe sex compared to the women, with the most distinguishing features being younger age at first intercourse (P < 0.0005), higher numbers of sex partners during lifetime (P = 0.001) and latest 6 months (P < 0.0005), more frequently consuming alcohol (P < 0.0005), poorer knowledge of STI/HIV prevention measures (P < 0.0005), and less positive attitudes towards safe sex (P = 0.001). However, no significant predictors of STI positivity were found in the men. In the women, the strongest predictors of STI positivity were young age (15-19 years) and multiple sex partners (≥ 2) during latest 6 months.

CONCLUSIONS

The overall prevalence of STIs among users of STI services at youth clinics in St. Petersburg was high. Comprehensive epidemiological data on STI prevalence and sexual behaviour correlates are necessary to initiate new and strengthen existing STI prevention programmes for the youth, in Russia as well as in many other settings.

Predictors and confounders of unprotected sex: A UK web-based study

OBJECTIVES

To evaluate the effects of gender, sex orientation, age, relationship status, age at first sex education, age at first sex, frequency of sex and number of sexual partners on the likelihood of unprotected sex in the United Kingdom (UK).

METHODS

A web-based survey was conducted in the UK in 2004 with 10,138 respondents. Eight variables were chosen as potential predictors of unprotected sex. Responses from sexually active participants were combined and crude/adjusted odds ratios (AORs) were calculated for binary/categorical variables.

RESULTS

No differences were found in AOR for gender, sex orientation, relationship status and frequency of sex. Differences were found in AOR for age, sex education, age at first sex and number of sexual partners, e.g. AOR 21-24 years of age versus under 16 (1.92, CI 1.38-2.68; p-value < 0.001); AOR sex education never received versus first sex education under 10 years of age (1.45, CI 1.12-1.87; p-value < 0.01); AOR first sex at 20 years versus at 14 years (0.56, CI 0.40-0.79; p-value < 0.01); and AOR 11-20 partners versus one partner (24.91, CI 20.02-30.98; p-value < 0.001). The association of sex orientation and relationship status with unprotected sex is confounded by the number of sexual partners.

CONCLUSIONS

UK health and education authorities should develop strategies to provide sex education starting in primary school and continuing throughout secondary school. Prevention programs and policies should focus on particular sexual behaviours. Furthermore, an understanding of sexual diversity and reducing stigmatisation of sexual orientation is necessary.

Oral contraception and unprotected sex with occasional partners of women HIV-infected through injection drug use

Among HIV-infected women, unprotected sex with the main sexual partner is common practice. Conversely, studies about condom use with sexual partners of unknown HIV sero-status are sparsely reported. We aimed to assess the impact of oral contraception on unsafe sexual behaviours with occasional partners in women HIV-infected through injection drug use. The analysis focused on 90 women, enrolled in the French cohort MANIF 2000 and reported having engaged in sexual relationships with occasional partners during a 48-month period. Visits where women reported unprotected sex with occasional partners in the prior 6 months were compared to visits where they reported protected sex using a logistic model based on Generalised Estimating Equations. Unprotected sex with occasional partners was independently associated with oral contraception (OR[95%CI] = 3.2[1.4-7.2]), reporting only one occasional partner (OR[95%CI] = 3.1[1.6-6.2]) and antiretroviral treatment receipt. No significant association was found between unprotected sex and CD4 level or plasma viral load. With the growing population of people living with HIV as a chronic infection, the development and evaluation of HIV-prevention interventions tailored toward women remain a public health priority. Risk reduction counselling and interventions are needed to promote either the use of dual contraception or, alternatively, that of female condom.

Gender differences in sexual behaviours in response to genitourinary symptoms

OBJECTIVE

To understand gender differences in sexual behaviours in response to genitourinary symptoms.

METHODS

473 (239 female and 234 male) subjects were enrolled at an STD clinic regardless of symptoms or infection status. Subjects completed a 30 day calendar recall interview of genitourinary symptoms, coital activity, sexual partners, and condom use.

RESULTS

Of the total of 473 participants, 261 (55%) reported symptoms (61% women and 39% men). STI prevalence was 73% and 75% for symptomatic women and men, respectively. For black women the probability of coitus was decreased in the presence of vaginal discharge (OR 0.64, 95% CI 0.47 to 0.89). No change in coital activity was seen in non-black women in the presence of vaginal discharge. Having vaginal discharge did increase the likelihood of condom use by their partners (OR 2.48, 95% CI 1.05 to 5.88), if coitus occurred. Urethral discharge was not associated with coitus or condom use in men. However, in men, dysuria was associated with increased likelihood of condom use (OR 4.25, 95% CI 1.57 to 11.56) if coitus occurred.

CONCLUSION

Black women altered both coital activity and condom use behaviours in response to vaginal discharge. In contrast, non-black women did not modify coital activity. Men increased condom use when having dysuria but did not alter coital activity. Changes in sexual behaviours may alter the risk of STI transmission independent of interactions with the healthcare system. STI education and prevention programmes need to better understand these gender and racial differences in developing effective strategies to reduce STI transmission.

Sexual risk following a sexually transmitted disease diagnosis: the more things change the more they stay the same

The purpose of this study is to assess changes in sexual risk behaviors, attitudes toward using condoms, and perceived susceptibility to fiuture STDs for adolescent females who recently were diagnosed with an incident STD compared to those who were not diagnosed with an incident STD. Adolescent females (N = 308) were assessed at two time points, 6 months apart. Ninety-two participants were diagnosed with an STD, and 216 were not diagnosed with an STD in between the two time points. Results indicated that adolescents did not significantly change their behaviors, attitudes, or perceptions following the diagnosis of an incident STD compared to those who were not diagnosed with an incident STD. This suggests that an STD diagnosis alone is not sufficient to motivate adolescent females to reduce their sexual risk behavior and change their sexual risk attitudes and perceptions.

The emotional experience of intercourse and sexually transmitted diseases: a decision-tree analysis

BACKGROUND

Epidemiologic data document high risks for many sexually transmitted diseases (STDs) among US adolescents and young adults.

GOAL

This case-control study used decision trees to investigate the relationship between STD incidence and emotional reactions to intercourse.

STUDY DESIGN

For this study, 188 adolescents and young adults (mean age, 24.9 years [SD = 8.2]) at a regional public STD clinic completed a behavioral and psychological questionnaire and underwent a workup for STD.

RESULTS

The prevalence of STD in this group was 44.8%. Decision-tree analysis identified emotional reactions to intercourse that were associated with STD diagnosis for some patients: feeling good about oneself after sex half the time or less (OR = 3.21; 95% CI = 1.73-5.95), feeling comfortable during sex half the time or less (OR = 2.17; 95% CI = 1.07-4.40), and feeling angry after sex (OR = 1.90; 95% CI = 0.91-3.99). Findings of a logistic regression model of emotional reactions to intercourse were significant (chi-square = 24.6; df = 8; P < 0.002), but adding behavioral variables did not improve prediction.

CONCLUSIONS

For some of these young adults at the time of life when they are at highest risk of STD, emotional factors have higher odds ratios for STD diagnosis than the traditionally assessed behavioral variables. This underscores the need for interventions targeted to specific subgroups and for readily available mental health services.

A cluster randomized trial of a sex education programme in Belize, Central America

BACKGROUND

Concerns about adverse consequences of early childbearing and risk of sexually transmitted diseases (STD) have renewed interest in the sexual behaviour of adolescents in developing countries, where they represent a large proportion of the population and are at highest risk. To date, little is known about the sexual knowledge of adolescents in developing countries. This study's primary objective was to evaluate the effectiveness of a responsible sexuality education programme (RSP) in changing knowledge associated with sex and sexuality; secondary objectives were to evaluate changes in attitudes and behavioural intent.

METHODS

A cluster randomized design randomizing high school classes in Belize City. Subjects were 13-19 years old.

RESULTS

Seven schools in Belize City were selected; 8 classrooms were randomized to the intervention arm and 11 classrooms to the control arm (N = 399). The intervention was associated with two more correct answers on the post-test (difference score was 2.22 points, 95% CI = 0.53, 3.91) after adjusting for gender and previous sexual experience. After controlling for gender and previous sexual experience, the intervention was associated with no change in the attitudes (0.06, 95% CI: -2.89, 2.82) or behavioural intent domains (0.84, 95% CI: -1.12, 2.46).

CONCLUSIONS

Greater changes in knowledge were observed in the intervention group than in the control group following the intervention. Changes were not observed for the attitude or behavioural intent domains. These results and the results of similar studies may be used to further improve sex education programmes as it is imperative that students have access to the information necessary to make informed decisions regarding their sexual health.

Post-treatment sexual and prevention behaviours of adolescents with sexually transmitted infections

OBJECTIVE

To evaluate sexual behaviour (including abstinence), sex partner change, and condom use during the 3 month period following treatment for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, or non-gonococcal urethritis.

METHODS

251 14-21 year old participants (83% female; 83% African-American) diagnosed with gonorrhoea, chlamydia, trichomonas, or non-gonococcal urethritis or sexual contacts of infected partners. Participants were clients of a public sexually transmitted diseases clinic or primary care adolescent clinics. Data were collected by structured interview at treatment, 1 month post-treatment, and 3 months post-treatment. At each visit, participants were asked about coital frequency and condom use for each recent partner. At 1 month, participants were asked when coitus occurred following treatment. At each follow up visit, sex partners were compared to partners named at treatment and classified as "same partner(s)," "new partner(s)," or both "same and new partner(s)."

RESULTS

Post-treatment abstinence was reported by 26% and 19% for the 1 month and 3 month visits, respectively. Abstinence was associated with greater likelihood of infection at enrolment although abstainers reported fewer lifetime STI and fewer lifetime sex partners. A substantial proportion of participants reported additional sexual contact with a previous partner. The average proportion of condom protected coital events increased from about 45% at enrolment to 64% at 1 month and 58% at 3 months (p<0.05). Higher levels were sustained for the 3 months following treatment.

CONCLUSIONS

Many adolescents adopt, at least temporarily, risk reduction behaviours such as abstinence or increased condom use. Sexual re-exposure to potentially untreated previous partners may increase risk of subsequent reinfection.

Association of adolescents' history of sexually transmitted disease (STD) and their current high-risk behavior and STD status: a case for intensifying clinic-based prevention efforts

BACKGROUND

Adolescents are at high risk of sexually transmitted disease (STD)/HIV infection, and one vulnerable subgroup is African American females. The association between adolescents' previous experience of STD and recent sexual risk behaviors has been ill-defined.

GOAL

The goal was to examine the associations between adolescents' self-reported history of STD diagnosis and current sexual risk behaviors, prevention knowledge and attitudes, and STD infection status.

STUDY DESIGN

This was a cross-sectional survey. Recruitment sites were in low-income neighborhoods of Birmingham, Alabama, characterized by high rates of unemployment, substance abuse, violence, and STDs. Participants were sexually active adolescent females (N = 522) 14 to 18 years of age. Information on STD history and current sexual behaviors (within the 30 days before assessment) was collected in face-to-face interviews. Less sensitive topics, such as STD prevention knowledge, attitudes about condom use, and perceived barriers to condom use, were addressed via self-administered survey. DNA amplification of vaginal swab specimens provided by the adolescents was performed to determine current STD status. Outcomes associated with past STD diagnosis were determined by means of logistic regression to calculate adjusted odds ratios (AORs) in the presence of observed covariates.

RESULTS

Twenty-six percent of adolescents reported ever having an STD diagnosed. Although past STD diagnosis was associated with increased STD prevention knowledge, it was not associated with increased motivation to use condoms. Compared with adolescents who had never had an STD, adolescents with a history of diagnosed STD were more likely to report not using a condom at most recent intercourse (AOR = 2.54; 95% CI = 1.64-3.93; = 0.0001), recent unprotected vaginal intercourse (AOR = 1.79; 95% CI = 1.15-2.79; = 0.010), inconsistent condom use (AOR = 2.27; 95% CI = 1.46-3.51; < .0001), sexual intercourse while drinking alcohol (AOR = 2.09; 95% CI = 1.33-3.28; = 0.001), and unprotected intercourse with multiple partners (AOR = 3.29; 95% CI = 1.09-9.89; = 0.034). Past STD diagnosis was associated with increased risk for current biologically confirmed gonorrhea and trichomoniasis (AOR = 2.48; 95% CI = 1.09-5.23; = 0.030; and AOR = 2.05; 95% CI = 1.18-3.59; = 0.011, respectively). Past STD diagnosis was not significantly associated with increased risk of current biologically confirmed chlamydia (AOR = 0.78; 95% CI = 0.45-1.37; = 0.38).

CONCLUSION

Among this sample of female adolescents, past STD diagnosis was an indicator of current high-risk sexual activity and increased risk for two common STDs: gonorrhea and trichomoniasis. Although adolescents may gain factual knowledge from the experience of having an STD diagnosed, they are not applying that knowledge to their current sexual behaviors. Thus, these adolescents remain at risk for subsequent STD infection. Therefore, the findings suggest that there is a need to intensify clinic-based prevention efforts directed toward adolescents with a history of STDs, as a strategy for reducing STD-associated risk behaviors and, consequently, the likelihood of new STD infections.

Determinants of persistent and recurrent Chlamydia trachomatis infection in young women: results of a multicenter cohort study

BACKGROUND

Sequelae of genital Chlamydia trachomatis infection in women are more strongly linked to repeat infections than to initial ones, and persistent or subsequent infections foster continued transmission.

OBJECTIVE

To identify factors associated with persistent and recurrent chlamydial infection in young women that might influence prevention strategies.

METHODS

Teenage and young adult women with uncomplicated C trachomatis infection attending reproductive health, sexually transmitted disease, and adolescent medicine clinics in five US cities were recruited to a cohort study. Persistent or recurrent chlamydial infection was detected by ligase chain reaction (LCR) testing of urine 1 month and 4 months after treatment.

RESULTS

Among 1,194 women treated for chlamydial infection, 792 (66.4%) returned for the first follow-up visit, 50 (6.3 %) of whom had positive LCR results. At that visit, women who resumed sex since treatment were more likely to have chlamydial infection (relative risk [RR], 2.0; 95% CI, 1.03-3.9), as were those who did not complete treatment (RR, 3.4; 95% CI, 1.6-7.3). Among women who tested negative for C trachomatis at the first follow-up visit, 36 (7.1%) of 505 had positive results by LCR at the second follow-up visit. Reinfection at this visit was not clearly associated with having a new sex partner or other sexual behavior risks; new infection was likely due to resumption of sex with untreated partners. Overall, 13.4% of women had persistent infection or became reinfected after a median of 4.3 months, a rate of 33 infections per 1,000 person months.

CONCLUSIONS

Persistent or recurrent infection is very common in young women with chlamydial infection. Improved strategies are needed to assure treatment of women's male sex partners. Rescreening, or retesting of women for chlamydial infection a few months after treatment, also is recommended as a routine chlamydia prevention strategy.
