Does douching increase risk for sexually transmitted infections? A prospective study in high-risk adolescents

Prevalence of sexually transmitted infections (STIs), associations with sociodemographic and behavioural factors, and assessment of the syndromic management of vaginal discharge in women with urogenital complaints in Mozambique

In Mozambique, sexually transmitted infections (STIs) are estimated to be prevalent, but diagnosis and treatment of curable STIs rely only on syndromic management. We examined the prevalence of four non-viral STIs and HIV-1/2, based on etiological diagnosis, associations with sociodemographic and behavioural factors, and the STI diagnostic accuracy of the vaginal discharge syndromic management in women with urogenital complaints in Maputo, Mozambique. A cross-sectional study was performed in Maputo, Mozambique, February 2018-January 2019, enrolling 924 women of reproductive age with urogenital complaints. Endocervical/vaginal swabs were sampled and chlamydia, gonorrhoea, trichomoniasis and Mycoplasma genitalium infections were diagnosed using a multiplex real-time PCR (AmpliSens; InterLabServices). Serological testing was performed for HIV-1/2. A structured questionnaire collected metadata. All data were analyzed in STATA/IC 12.1 using descriptive statistics, chi-square tests and logistic regression model. About 40% of the women were less than 24 years old, 50.8% were single, 62.1% had their sexual debut between 12 and 17 years of age, and the main complaint was vaginal discharge syndrome (85%). The prevalence of chlamydia was 15.5%, trichomoniasis 12.1%, gonorrhoea 4.0%, M. genitalium 2.1%, and HIV-1/2 22.3%. The vaginal discharge syndrome flowchart had a sensitivity of 73.0%-82.5% and a specificity of 14%-15% for the detection of any individual non-viral STI in women with urogenital complaints. In total, 19.2% of the symptomatic women with chlamydia, trichomoniasis or gonorrhoea would not be detected and accordingly treated using the vaginal discharge syndromic management (missed treatment) and 70.0% of the women would be treated despite not being infected with any of these three STIs (overtreatment). In conclusion, a high prevalence of especially chlamydia, trichomoniasis, and HIV-1/2 was found in women of childbearing age with urogenital complaints in Maputo, Mozambique. Syndromic management of vaginal discharge revealed low accuracy in the detection of STIs in symptomatic women, especially low specificity, which resulted in under-treatment of STI-positive cases and incorrect or over-treatment of women with urogenital complaints, many of whom were negative for all the non-viral STIs. Etiological diagnosis is imperative for effective management of STIs in symptomatic and asymptomatic women.

The Vaginal Microbiome in Health and Disease-What Role Do Common Intimate Hygiene Practices Play?

The vaginal microbiome is a dynamic, sensitive microenvironment. The hallmark of a 'healthy' vaginal microbiome is currently believed to be one dominated by Lactobacillus spp., which acidifies the vaginal environment and help to protect against invading pathogens. However, a 'normal' microbiome is often difficult, if not impossible, to characterise given that it varies in response to numerous variables, including pregnancy, the menstrual cycle, contraceptive use, diet, ethnicity, and stress. A Lactobacillus-depleted microbiome has been linked to a variety of adverse vaginal health outcomes, including preterm birth (PTB), bacterial vaginosis (BV), and increased risk of sexually transmitted infections. The latter two of these have also been associated with feminine intimate hygiene practices, many of which are practised without any evidence of health benefits. The most extensively studied practice is vaginal douching, which is known to cause vaginal dysbiosis, predisposing women to BV, pelvic inflammatory disease, and PTB. However, little is known of the impact that intimate hygiene practices and associated products have on the vaginal microbiome. This review aims to outline the major factors influencing the vaginal microbiome and common vaginal infections, as well as to summarise current research surrounding the impact of hygiene products and practices on the vaginal microbiome.

Knowledge, experiences, and practices of women affected by female genital schistosomiasis in rural Madagascar: A qualitative study on disease perception, health impairment and social impact

BACKGROUND

Female genital schistosomiasis (FGS) is a neglected manifestation of urogenital schistosomiasis caused by S. haematobium. The disease presents with symptoms such as pelvic pain, vaginal discharge and bleeding and menstruation disorders, and might lead to infertility and pregnancy complications. The perspectives of women with FGS have not been studied systematically. The aim of the study was to understand knowledge, experiences, and practices of women with FGS.

METHODS

We performed a qualitative study with seventy-six women diagnosed of having FGS, in the Ambanja district in Northwest Madagascar. Data collection was either through focus group discussion (N = 60) or in an individual semi-structured interview (N = 16). FGS was diagnosed by colposcopy. The data was analysed using Mayring´s qualitative content analysis.

RESULTS

Knowledge on how the disease is acquired varied and ideas on prevention remained vague. Patients suffered from vaginal discharge and pelvic complaints. Some women expressed unbearable pain during sexual intercourse and compared their pain to an open wound being touched. FGS considerably impaired women´s daily activities and their quality of life. Infertility led to resignation and despair, conflicts with the partner and to social exclusion from the community. Women fearing to sexually transmit FGS refrained from partnership and sexual relations. Many women with FGS reported stigmatisation. A coping strategy was to share strain with other women having similar complaints. However, concealing FGS was a common behaviour which led to social isolation and delayed health care seeking.

CONCLUSIONS

Our study underlines that FGS has an important impact on the sexual health of women and on their social life in the community. Our results highlight the importance of providing adequate health education and structural interventions, such as the supply of water and the provision of sanitation measures. Further, correct diagnosis and treatment of FGS in adolescent girls and women should be available in all S. haematobium-endemic areas.

TRIAL REGISTRATION

The qualitative study was embedded in a randomised controlled trial (RCT) in which two doses of praziquantel were compared (https://clinicaltrials.gov/ct2/show/NCT04115072).

Understanding Women's Vaginal Douching Behaviors and Practices for Consideration in the Development of a Potential Future Vaginal Microbicide Douche for HIV Prevention: A Systematic Review of the Literature

Despite clinicians consistently advising against vaginal douching, 29-92% of women worldwide report douching. This review documents women's douching practices, motivations for douching, and specific associations (or absence of associations) between vaginal douche use and vaginal outcomes thought to be associated with douching. Understanding women's existing douching behaviors and vaginal health outcomes is critical for developing a safe vaginal microbicide douche that can be used as HIV pre-exposure prophylaxis (PrEP). A vaginal douche as PrEP could help prevent new HIV infections, since emerging evidence shows some women discontinue oral PrEP. We performed a systematic review of the literature using the guidelines for Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). Articles included in the analysis (N = 48) were published 2009-2019 in English and focused on women's experiences with douching. Two trained independent reviewers assessed these articles for content on vaginal douching, including racial/ethnic focus of studies, study design, sampling, women's reasons for douching, contents of douche solutions, and associations between vaginal douching and vaginal health outcomes. Several studies focused on Black women (N = 12 studies) or had no racial/ethnic focus (N = 12). Just over half of all studies (N = 24) were cross-sectional and involved a self-reported questionnaire and lab samples. Studies sampled women from health clinics where they were (N = 13) or were not (N = 14) presenting for vaginal health complaints. Women's primary motivation for douching was for "general cleanliness" (N = 13), and most douche solutions contained water (N = 12). There was little empirical agreement between vaginal douche use and most vaginal health outcomes. Future studies of PrEP vaginal douches should be well controlled and prioritize safety to ensure positive vaginal health outcomes.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

"Feeling clean": stigma and intravaginal practices among female entertainment workers in Cambodia

Background

Intravaginal practices (IVPs), methods used by women most often to manage vaginal hygiene and address perceived disruptions to vaginal health, may increase the risk of contracting human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). This qualitative study explores the social, professional, and peer context surrounding IVPs, the experiences of self-cleaning or getting cleaned from a health professional, and the perceived impacts of IVPs among female entertainment workers (FEWs) in Cambodia.

Methods

In 2017, we conducted 27 focus group discussions from four provinces, and 16 follow-up semi-structured in-depth interviews with purposively selected participants in two provinces. Data collection occurred over three weeks, with concurrent data transcription and translation. The data from the transcripts were analyzed using Dedoose, an online, open-access qualitative analysis software. Two researchers independently labeled sections of transcripts associated with broader categories and subcategories based on the initial content analysis matrix and created codes. This process continued iteratively until a final coding schema and conceptual model was created.

Results

We found that IVPs are widely practiced among FEWs in Cambodia and are associated with internalized and enacted stigma. Stigma was an overarching theme that impacted the sub-themes of (1) messages about cleaning, (2) the cleaning process, and (3) the impact of cleaning. Experiences of enacted stigma and internalized stigma permeated conversations about IVP, including feeling pressured by peers to keep themselves clean, practicing internal cleaning after transactional sex, and being called dirty by health providers.

Conclusions

FEWs who practice IVP talk about it in the context of their lived experiences stigma and discrimination. Highly stigmatized practices such as IVP among FEWs may benefit from a harm reduction approach that emphasizes positive changes without judgment, coercion, or discrimination.

Exploring the Vaginal Microbiome and Intravaginal Practices in Postmenopausal Women

BACKGROUND

Evidence suggests that intravaginal practices (IVPs) women use to cleanse their vagina or enhance sexual pleasure may be associated with unhealthy changes in the vaginal microbiome (VM). However, the effects of these practices in postmenopausal women are unknown.

OBJECTIVES

The objective of this pilot study was to characterize the VM communities of postmenopausal women, identify types and frequency of IVPs, and explore associations between the VM and IVPs in postmenopausal women.

METHODS

We analyzed the VM data of 21 postmenopausal women in Atlanta, Georgia, from vaginal swabs collected at a routine gynecological visit. 16S rRNA gene sequencing in the V3-V4 region was used to characterize the VM. In addition, we described the IVPs of these women, identified by using our newly developed instrument: the Vaginal Cleansing Practices Questionnaire. The associations between the VM and IVPs were explored by comparing the alpha diversities, beta diversities, and the relative abundances at both the community level and individual genus level.

RESULTS

The most abundant known bacterial genus found in the VM samples was Lactobacillus (35.7%), followed by Prevotella (21.4%). Eleven women (52%) reported using at least one type of IVP since menopause. The most common type of IVP was soap and water to clean inside the vagina. The use of IVPs was not associated with any alpha diversity metric, including Shannon index, inverse Simpson index, and Chao1 index; beta diversity metric, including Bray-Curtis and Jaccard distances; nor relative abundances at the community and individual genus level. Sociodemographic factors were also not associated with any alpha diversity metric.

DISCUSSION

Clinicians must assess IVPs and other vaginal and sexual hygiene practices of women of all ages to educate and promote healthy behaviors. More than half of the postmenopausal women in this pilot study use IVPs. Understanding the reasoning behind participants' use of IVPs and their perceptions of the possible effects of these practices will require further research. Although the small sample did not show associations with the VM, more extensive studies are warranted.

Vaginal herb use and Chlamydia trachomatis infection: cross-sectional study among women of various ethnic groups in Suriname

OBJECTIVE

Vaginal steam baths with herb leaves (herb use) is practised by some Surinamese women. We assessed herb use among women from the five most prevalent ethnic groups, and if herb use is associated with Chlamydia trachomatis infection.

SETTING

Participants were recruited at a sexually transmitted infection (STI) clinic and a family planning clinic (FP) in Paramaribo, Suriname.

PARTICIPANTS

1040 women were included subsequently, comprising the following ethnic groups: Creole (26.7%), Hindustani (24.6%), Javanese (15.7%), Maroon (13.3%) and mixed descent (19.7%).

METHODS

Nurses collected a questionnaire and vaginal swabs for nucleic acid amplification C. trachomatis testing.

PRIMARY OUTCOMES

Determinants of vaginal herb use and C. trachomatis infection via univariable and multivariable logistic regression.

RESULTS

Herb use was most common among Maroon (68.8%) and Creole women (25.2%). In multivariable analysis including only Maroon and Creole women, determinants significantly associated with vaginal herb use were (OR; 95% CI): Maroon ethnic descent (5.33; 3.26 to 8.71 vs Creole), recruitment at the STI clinic (2.04; 1.24 to 3.36 vs FP), lower education levels (3.80; 1.68 to 8.57 lower vs higher, and 2.02; 0.90 to 4.51 middle vs higher). Lower age and recruitment at the STI clinic were associated with C. trachomatis infection, but not vaginal herb use.

CONCLUSION

In Suriname, vaginal herb use is common among Maroon and Creole women. Education, ethnic group and recruitment site were determinants for herb use. Vaginal herb use was not a determinant of C. trachomatis infection. Future research should focus on the effect of herb use on the vaginal microbiome and mucosal barrier.

Vaginal washing and lubrication among female sex workers in the Mexico-US border region: implications for the development of vaginal PrEP for HIV prevention

Background

To assess the potential acceptability and inform the development of behaviorally-congruent vaginal douche- or gel-based HIV pre-exposure prophylaxis (PrEP) products, we examined vaginal washing and lubrication practices among female sex workers (FSWs) in Tijuana and Ciudad Juarez, two northern Mexico cities bordering the United States (US).

Methods

Two hundred and ninety-five HIV-negative FSWs (145 Tijuana; 150 Ciudad Juarez) enrolled in a behavioral HIV prevention intervention trial completed surveys assessing vaginal washing and lubrication practices, as well as motivators and barriers to performing each practice. Logistic regression was used to identify potential predictors of each practice in the past month.

Results

In the past month, vaginal washing was performed by 56 and 22% of FSWs in Tijuana and Ciudad Juarez (p <  0.0001), respectively, while vaginal lubrication was performed by 64 and 45% of FSWs in Tijuana and Ciudad Juarez (p = 0.001), respectively. Vaginal washing was positively associated with living in Tijuana (adjusted odds ratio [AOR] = 4.35, 95% confidence interval [CI]: 2.60–7.30), older age (AOR = 1.04 per year, 95% CI: 1.01–1.06), and vaginal lubrication (AOR = 2.99, 95% CI: 1.67–5.35), while it was negatively associated with being born in the same state as the study site (AOR = 0.50, 95% CI: 0.31–0.82), earning a monthly income ≥3500 pesos (AOR = 0.53, 95% CI: 0.28–1.00), and hazardous alcohol consumption (AOR = 0.56, 95% CI: 0.33–0.95). Vaginal lubrication was positively associated with living in Tijuana (AOR = 2.21, 95% CI: 1.37–3.54) and vaginal washing (AOR = 2.91, 95% CI: 1.64–5.18), while it was negatively associated with being born in the same state as the study site (AOR = 0.47, 95% CI: 0.29–0.75).

Conclusions

The moderate and high prevalence of vaginal washing and lubrication, respectively, suggest behaviorally-congruent, multi-purpose, vaginal douche- and gel-based PrEP products that simultaneously address FSWs’ needs and prevent HIV infection may be acceptable to many FSWs along the Mexico-US border. Future product development and implementation should also consider the link between vaginal washing and lubrication to ensure existing practices do not undermine vaginal PrEP product effectiveness.

Intravaginal practices and genital human papillomavirus infection among female sex workers in Cambodia

OBJECTIVES

Intravaginal practices (IVPs) include washing, wiping, or inserting something inside the vagina. This study investigates the associations between IVPs and genital human papillomavirus (HPV) infection.

METHODS

We conducted a cross-sectional study of 200 female sex workers aged 18 to 35 years in Phnom Penh, Cambodia. From August to September 2014. Data on sociodemographic characteristics, IVPs, and other behaviors were collected through face-to-face interviews. Self-collected cervicovaginal specimens were tested for 37 HPV genotypes.

RESULTS

Multivariable Poisson regression models showed that a lower number of infecting HPV genotypes were associated with intravaginal washing in the past 3 months (incident rate ratios [IRR] = 0.65, 95% confidence interval [CI]: 0.46-0.94) and often performing intravaginal washing shortly after sex (IRR = 0.89, 95% CI: 0.81-0.99). Intravaginal washing before vaginal sex, intravaginal wiping, and intravaginal insertion were not associated with HPV infection.

CONCLUSION

These findings challenge the existing view that all types of vaginal cleansing are harmful. Specifically, intravaginal washing shortly after sex (mainly with water) may help prevent HPV infection in female sex workers, who have several partners and thus frequently expose to sources of HPV infection with different genotypes.

Intravaginal practices are associated with greater odds of high-risk HPV infection in Haitian women

OBJECTIVE

Haitian women have the highest incidence of cervical cancer within the Western hemisphere. Intravaginal hygiene practices have been linked with human papilloma virus (HPV) infection and cervical dysplasia. These practices, known as 'twalet deba' in Haitian Creole, are common among Haitian women and are performed with various natural and synthetic agents. As part of a community-based participatory research initiative aimed at reducing cervical cancer disparities in rural Haiti, we explored the use of intravaginal agents and their associations with high-risk HPV infection.

DESIGN

Community Health Workers recruited 416 women for cervical self-sampling from two neighborhoods within Thomonde, Haiti. Participants were interviewed regarding intravaginal hygiene practices and completed a cervical self-sampling procedure. Cervical samples were analyzed for the presence of high-risk HPV infection. Associations between each intravaginal agent and high-risk HPV infection were examined via univariate logistic regression analyses, as well as via multivariate analyses controlling for sociodemographic factors and concurrent agent use.

RESULTS

Nearly all women (97.1%) performed twalet deba, using a variety of herbal and commercially produced intravaginal agents. Approximately 11% of the participants tested positive for high-risk HPV. Pigeon pea and lime juice were the only agents found to be associated with high-risk HPV in the univariate analyses, with women who used these agents being approximately twice as likely to have high-risk HPV as those who did not. Only pigeon pea remained significantly associated with high-risk HPV after controlling for sociodemographic factors and concurrent agent use.

CONCLUSION

Two agents, pigeon pea and lime juice, may contribute to risk for HPV infection in this population. Results suggest that in addition to cervical cancer screening interventions, future preventive initiatives should focus on minimizing risk by advocating for the use of less-toxic twalet deba alternatives.

Addressing intravaginal practices in women with HIV and at-risk for HIV infection, a mixed methods pilot study

Intravaginal practices (IVPs), include intravaginal cleansing (cleansing the inside of the vagina) or intravaginal insertion of products for hygiene, health or sexuality reasons. IVPs are associated with adverse female health outcomes, development of bacterial vaginosis, HIV acquisition and transmission. A mixed methods approach was used in this study to examine the prevalence of IVP, assess reasons for engagement, and perceptions of IVP among a sample of minority (African-American and Hispanic) women infected, or at-risk, for HIV in Miami, USA, a city with increasing numbers of sexually transmitted infections (STIs) and HIV. Three focus groups (total n=20) and quantitative assessments (n=72) were conducted with women infected or uninfected with HIV. In the qualitative assessments, most women reported engaging in both intravaginal cleansing and intravaginal insertion, and stated the main motivation for IVP was hygiene. The quantitative assessments confirmed that cleansing with water alone, soap with water or using commercial douches was common, as well as intravaginal insertion using a cloth or a rag in both HIV-infected and uninfected women. Women with HIV infection reported less use of water and water and soap for IVPs, and reported learning about the potential harm of IVP from their HIV health care providers. Despite their health risks, IVP appeared common in both HIV-infected and at-risk minority women, and interventions to decrease IVP could have important health implications among populations with high rates of IVP, STIs and HIV.

Intravaginal Practices in Female Sex Workers in Cambodia: A Qualitative Study

Intravaginal practices (IVPs) are associated with several adverse health outcomes, including HIV infection. However, few studies have examined this topic in Asian cultures, particularly in female sex workers (FSWs). This theory-based qualitative study aimed to describe the IVPs and to identify salient determinants of these practices in FSWs in Phnom Penh, Cambodia. We conducted in-depth interviews using open-ended questions with 30 FSWs in July-August 2014. We analyzed data using thematic content analysis, with thematic codes based on the constructs of the theory of planned behavior. The results showed that the most common IVP was a combination of intravaginal washing and wiping, to which we refer as intravaginal cleansing. There was a clear and close connection between IVP and sex work. Perceived benefits of intravaginal cleansing were numerous, while the perceived risks were few. As a result, the attitude toward intravaginal cleansing was favorable. A common misperception of benefit was that intravaginal cleansing could prevent sexually transmitted infections. Local physicians considerably influenced the subjective norm related to IVP. Intention to quit IVPs was suboptimal. In conclusion, the psychological factors associated with IVPs in FSWs were somewhat different from those in the general population of Cambodian women and women in other countries. Behavioral beliefs, attitude, and subjective norms appeared salient and important factors in IVPs. Interventions aimed at reducing IVPs should target these constructs as well as the sex-work-associated economic motives. Local physicians may be an agent to change IVP and an effective channel to deliver interventions.

Home Screening for Bacterial Vaginosis to Prevent Sexually Transmitted Diseases

BACKGROUND

Longitudinal studies have consistently found a significant association between bacterial vaginosis (BV) and acquisition of sexually transmitted diseases. However, there are limited prospective data to confirm these findings.

METHODS

We conducted a prospective, randomized, open-label trial of home screening and treatment of young women with asymptomatic BV who were also at high risk for sexually transmitted diseases. These women were screened every 2 months for 12 months and randomized to treatment with oral metronidazole 500 mg twice daily for 7 days or observation alone. The primary outcome was the incidence of gonorrhea and/or chlamydia.

RESULTS

A total of 1365 subjects were enrolled in the study across 10 sites. Adherence with mailing specimens obtained at home was excellent in both groups (84%-88%). The incidence of gonorrhea and/or chlamydia was 19.1 per 100 person-years (95% confidence interval, 15.1-22.1) for the treatment group and 18.5 per 100 person-years (15.1-22.8) for the observation arm, a difference that was not statistically significant.

CONCLUSIONS

Young women were very amenable to home screening for BV, gonorrhea, and chlamydia. Treatment of asymptomatic BV with 1 week of oral metronidazole did not decrease the incidence of gonorrhea and/or chlamydia.

Sexually transmitted diseases treatment guidelines, 2015

These guidelines for the treatment of persons who have or are at risk for sexually transmitted diseases (STDs) were updated by CDC after consultation with a group of professionals knowledgeable in the field of STDs who met in Atlanta on April 30-May 2, 2013. The information in this report updates the Sexually Transmitted Diseases Treatment Guidelines, 2010 (MMWR Recomm Rep 2010;59 [No. RR-12]). These updated guidelines discuss 1) alternative treatment regimens for Neisseria gonorrhoeae; 2) the use of nucleic acid amplification tests for the diagnosis of trichomoniasis; 3) alternative treatment options for genital warts; 4) the role of Mycoplasma genitalium in urethritis/cervicitis and treatment-related implications; 5) updated HPV vaccine recommendations and counseling messages; 6) the management of persons who are transgender; 7) annual testing for hepatitis C in persons with HIV infection; 8) updated recommendations for diagnostic evaluation of urethritis; and 9) retesting to detect repeat infection. Physicians and other health-care providers can use these guidelines to assist in the prevention and treatment of STDs.

Prevalence of vulvovaginal candidiasis, trichomoniasis and bacterial vaginosis among pregnant women receiving antenatal care in Southwestern Nigeria

Vaginal infections in pregnancy are associated with considerable discomfort and adverse pregnancy outcomes including preterm delivery, low birth weight and increased infant mortality and also predisposition to HIV/AIDS. This study evaluated the prevalence and factors associated with vulvovaginal candidiasis, trichomoniasis and bacterial vaginosis among women attending antenatal clinic at a hospital in Nigeria. A semi-structured questionnaire was administered and high vaginal swab samples were obtained from consenting pregnant women. The samples were processed following standard protocols. The prevalence of vulvovaginal candidiasis was 36%, while those of trichomoniasis and bacterial vaginosis were 2% and 38%, respectively. Infections were higher in the third trimester and many women admitted to practices that increase risk of these infections. Significant association was found between recent intake of antibiotics and vaginal candidiasis, same association was also found with bacterial vaginosis. Adequate investigation and prompt treatment will reduce the morbidity and attendant effects of these prevalent infections on mother and fetus.

Prevalence of human papillomavirus in adolescent girls before reported sexual debut

BACKGROUND

Human papillomavirus (HPV) vaccines are recommended for girls prior to sexual debut because they are most effective if administered before girls acquire HPV. Little research has been done on HPV prevalence in girls who report not having passed sexual debut in high HPV-prevalence countries.

METHODS

Using attendance registers of randomly selected primary schools in the Mwanza region of Tanzania, we enrolled girls aged 15-16 years who reported not having passed sexual debut. A face-to-face interview on sexual behavior and intravaginal practices, and a nurse-assisted self-administered vaginal swab were performed. Swabs were tested for 13 high-risk and 24 low-risk HPV genotypes.

RESULTS

HPV was detected in 40/474 (8.4%; 95% confidence interval [CI], 5.9-11.0) girls. Ten different high-risk and 21 different low-risk genotypes were detected. High-risk genotypes were detected in 5.3% (95% CI, 3.5-7.8). In multivariable analysis, only intravaginal cleansing (practiced by 20.9%) was associated with HPV detection (adjusted odds ratio = 2.19, 95% CI, 1.09-4.39).

CONCLUSION

This cohort of adolescent Tanzanian girls had a high HPV prevalence prior to self-reported sexual debut, and this was associated with intravaginal cleansing. This most likely reflects underreporting of sexual activity, and it is possible that intravaginal cleansing is a marker for unreported sexual debut or nonpenetrative sexual behaviors.

Douching practices among female sex workers in Phnom Penh, Cambodia

Several studies indicate that douching has few benefits but numerous adverse health outcomes, including increased risk for sexually transmitted infections and HIV. No published study explores douching practices among Cambodian female sex workers. This report provides preliminary data about the prevalence and frequency of douching among female sex workers in Phnom Penh, Cambodia. Survey data were obtained from 81 female sex workers who were taken into custody due to engagement in commercial sex from March to June 2011. Results showed that 91% of participants douched. The mean numbers of times douched before sex and after sex per 10 sex episodes were 4.43 (SD = 3.87) and 4.63 (SD = 3.94), respectively. Half of the participants thought that douching could help to prevent sexually transmitted infections including HIV; 24% were unsure about this. Usually, douching after sex was associated with ever obtaining an HIV test (p = .012) and was marginally associated (although not statistically significant) with a higher average number of clients per week (p =. 063) and consistent condom use with clients (p = .053). This suggests that these practices may be related to individual perceptions of sexually transmitted infections/HIV risk or susceptibility. Given the commonness of douching and related misperceptions among Cambodian female sex workers, future studies and interventions are needed to prevent adverse health problems.

Examining targets for HIV prevention: intravaginal practices in Urban Lusaka, Zambia

Intravaginal practices (IVP) are the introduction of products inside the vagina for hygienic, health, or sexuality reasons. The influence of men and Alengizis, traditional marriage counselors for girls, in promoting IVP has not been explored. We conducted gender-concordant focus groups and key informant interviews with Alengizis. The responses were conducted grouped into three themes: (1) cultural norms, (2) types and reasons for IVP, and (3) health consequences. We found that IVP were used by all participants in our sample and were taught from generation to generation by friends, relatives, or Alengizis. The reasons for women to engage in IVP were hygienic, though men expect women to engage in IVP to enhance sexual pleasure. Approximately 40% of women are aware that IVP can facilitate genital infections, but felt they would not feel clean discontinuing IVP. All men were unaware of the vaginal damage caused by IVP, and were concerned about the loss of sexual pleasure if women discontinued IVP. Despite the health risks of IVP, IVP continue to be widespread in Zambia and an integral component of hygiene and sexuality. The frequency of IVP mandates exploration into methods to decrease or ameliorate their use as an essential component of HIV prevention.

Prevalence and types of rectal douches used for anal intercourse: results from an international survey

BACKGROUND

Rectal products used with anal intercourse (AI) may facilitate transmission of STIs/HIV. However, there is limited data on rectal douching behavior in populations practicing AI. We examined the content, types of products, rectal douching practices and risk behaviors among those reporting AI.

METHODS

From August 2011 to May 2012, 1,725 women and men reporting receptive AI in the past 3 months completed an internet-based survey on rectal douching practices. The survey was available in English, French, German, Mandarin, Portuguese, Russian, Spanish, and Thai and included questions on sexual behaviors associated with AI including rectal douching. Differences by rectal douching practices were evaluated using chi-square methods and associations between reported douching practices and other factors including age and reported STI history were evaluated using logistic regression analysis.

RESULTS

Respondents represented 112 countries, were mostly male (88%), and from North America (55%) or Europe (22%). Among the 1,339 respondents (66%) who reported rectal douching, most (83%) reported always/almost always douching before receptive AI. The majority of rectal douchers reported using non-commercial/homemade products (93%), with water being the most commonly used product (82%). Commercial products were used by 31%, with the most common product being saline-based (56%). Rectal douching varied by demographic and risk behaviors. The prevalence of rectal douching was higher among men (70% vs. 32%; p-value < .01), those reporting substance-use with sex (74% vs. 46%; p-value < .01), and those reporting an STI in the past year (69% vs. 57% p-value < .01) or ever testing HIV-positive (72% vs. 53%; p-value < .01). In multivariable analysis, adjusting for age, gender, region, condom and lubricant use, substance use, and HIV-status, douchers had a 74% increased odds of reporting STI in the past year as compared to non-douchers [adjusted odds ratio (AOR) = 1.74; 95% CI 1.01-3.00].

CONCLUSION

Given that rectal douching before receptive AI is common and because rectal douching was associated with other sexual risk behaviors the contribution of this practice to the transmission and acquisition of STIs including HIV may be important.

Trichomoniasis: the "neglected" sexually transmitted disease

Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million people in the United States. Although trichomoniasis is common, it has been considered a "neglected" sexually transmitted disease, due to limited knowledge of its sequelae and associated costs. This article reviews current epidemiology, pathophysiology, diagnostic methods, clinical management recommendations and special considerations, research on associated conditions and costs, prevention strategies, and controversies regarding trichomoniasis.

Intravaginal cleansing among women attending a sexually transmitted infection clinic in Kingston, Jamaica

OBJECTIVES

Although common worldwide, intravaginal cleansing is associated with poor health outcomes. We sought to describe intravaginal cleansing among women attending a sexually transmitted infection (STI) clinic in Jamaica.

METHODS

We examined intravaginal cleansing ("washing up inside the vagina", douching, and products or materials used) among 293 participants in a randomized trial of counselling messages at an STI clinic in Kingston. We focussed on information on intravaginal cleansing performed in the 30 days and three days preceding their baseline study visit. We describe reported cleansing behaviours and used logistic regression to identify correlates of intravaginal cleansing.

RESULTS

Fifty-eight per cent of participants reported intravaginal cleansing in the previous 30 days, and 46% did so in the three days before baseline. Among those who cleansed in the previous 30 days, 88% reported doing so for hygiene unrelated to sex, and three-fourths reported generally doing so more than once per day. Soap (usually with water) and water alone were the most common products used for washing; commercial douches or detergents were reported infrequently. Intravaginal cleansing in the three days before the baseline visit was positively associated with having more than one sex partner in the previous three months (adjusted odds ratio [AOR], 1.9; 95% CI, 1.1, 3.2), and negatively associated with experiencing itching in the genital area at baseline (AOR, 0.6; 95% CI, 0.4, 1.0).

CONCLUSIONS

A large proportion of women attending STI clinics in Jamaica engage in frequent intravaginal cleansing, indicating a need for clinicians to discuss this topic with them accordingly.

Incidence, prevalence, and epidemiology of herpes simplex virus-2 in HIV-1-positive and HIV-1-negative adolescents

BACKGROUND

Several studies have assessed risk factors associated with herpes simplex virus-2 (HSV-2) prevalence in adults; however, few have focused on HSV-2 incidence, particularly in adolescents. The objective of this study was to determine HSV-2 prevalence and incidence and associated risk factors in a HIV-1-positive and at risk HIV-1-negative adolescent population.

METHODS

Sera were tested for HSV-2 antibodies in 518 adolescents in the Reaching for Excellence in Adolescent Care and Health cohort at baseline and again at the final follow-up visit. Prevalence at baseline and incidence (per person years) of HSV-2 infection were calculated. Furthermore, among HIV-1-positive individuals, a subgroup analysis was performed to assess risk factors for HSV-2 infection. Conditional logistic regression was used to estimate odds ratios and P values for associations between CD4+ T-cell (CD4+) count, HIV-1 viral load (VL), and HSV-2 acquisition, adjusting for antiretroviral therapy use, other sexually transmitted infections, gender, race, and number of sexual partners.

RESULTS

At baseline, 179 (35%) subjects were HSV-2 positive, with an additional 47 (16%) new cases being identified during a median follow-up time of 1.95 years and an incidence rate of 7.35 cases per 100 person years. Several risk factors were associated with HSV-2 prevalence (being female, non-Hispanic, uncertainty of sexual preference, and HIV-1 positive) and incidence (using drugs, alcohol, and number of new sexual partners). Among HIV-1 positives, an increase in CD4+ count by 50 cell/mm(3) (odds ratio, 1.17; 95% CI, 1.04-1.31, P = 0.008) was associated with HSV-2 acquisition.

CONCLUSIONS

The high prevalence and incidence of HSV-2 infection among adolescents, compared with the general population at this age group suggests a critical need for screening and preventive programs among this targeted group.

Biopsychosocial factors associated with dyspareunia in a community sample of adolescent girls

Although various biopsychosocial factors have been associated with dyspareunia, research to date has focused on retrospective reports of adult women, and lack of consensus regarding etiology remains. By targeting girls at the beginning of their reproductive life, this study aimed to examine the biomedical, behavioral, and psychosocial correlates of chronic painful intercourse in sexually active adolescents compared to pain-free girls. With written informed consent, data were obtained from 1425 girls (12-19 year olds) from seven metropolitan high schools using self-report questionnaires pertaining to gynaecologic/biomedical history, physical/psychological/sexual abuse, anxiety, depression, attitudes towards sexuality, and social support. While the chronic painful intercourse (n = 51) and pain-free comparison group (n = 167) did not differ significantly on biomedical variables, painful intercourse was associated with significantly more pain during tampon insertion, and avoidance of tampons was linked to a fourfold risk of experiencing pain during sex. Cases also reported engaging in significantly more detrimental vulvar hygiene habits than pain-free girls, whereas no significant group differences were observed for self-treatment using over-the-counter antifungal preparations. Sexual abuse, fear of physical abuse, and trait anxiety were identified as significant psychosocial correlates of chronic painful intercourse. A logistic regression further identified pain during first tampon insertion and trait anxiety as statistical predictors of adolescent pain during intercourse. In addition to a possible intrinsic dysfunction in central pain processing, findings suggest that psychological variables, such as anxiety, play a significant role in painful intercourse's very first manifestations in adolescent girls.

Prevalence, motivations, and adverse effects of vaginal practices in Africa and Asia: findings from a multicountry household survey

BACKGROUND

Women worldwide use various vaginal practices to clean or modify their vulva and vagina. Additional population-level information is needed on prevalence and motivations for these practices, characteristics of users, and their adverse effects.

METHODS

This was a household survey using multistage cluster sampling in Tete, Mozambique; KwaZulu-Natal, South Africa; Yogyakarta, Indonesia; and Chonburi, Thailand. In 2006-2007, vaginal practices and their motivations were examined using structured interviews with women 18-60 years of age (n=3610).

RESULTS

Prevalence, frequency, and motivations varied markedly. Two thirds of women in Yogyakarta and Chonburi reported one or more practices. In Yogyakarta, nearly half ingest substances with vaginal effects, and in Chonburi, external washing and application predominate. In Tete, half reported three or four current practices, and a quarter reported five or more practices. Labial elongation was near universal, and 92% of those surveyed cleanse internally. Two third's in KwaZulu-Natal practiced internal cleansing. Insertion of traditional solid products was rare in Chonburi and Yogyakarta, but one tenth of women in KwaZulu-Natal and nearly two thirds of women in Tete do so. Multivariate analysis of the most common practice in each site showed these were more common among less educated women in Africa and young urban women in Asia. Explicit sexual motivations were frequent in KwaZulu-Natal and Tete, intended for pleasure and maintaining partner commitment. Practices in Chonburi and Yogyakarta were largely motivated by femininity and health. Genital irritation was common at African sites.

CONCLUSIONS

Vaginal practices are not as rare, exotic, or benign as sometimes assumed. Limited evidence of their biomedical consequences remains a concern; further investigation of their safety and sexual health implications is warranted.

The male sexual partners of adult versus teen women with sexually transmitted infections

OBJECTIVES

We compared the male sexual partners of teen girls of age 15 to 19 years, currently infected with a sexually transmitted infection (STI) versus the male partners of adult women of age 20 to 41 years, with an STI to determine risk factors in these high-risk sexual dyads related to the male partner.

STUDY DESIGN

Interview of 514 men who were partnered with 152 teen girls and 362 adult women, enrolled in Project Sexual Awareness for Everyone, a randomized controlled trial of behavioral intervention to reduce recurrent STIs.

RESULTS

Compared to the male partners of adult women, male partners of teen girls were significantly more likely (P < 0.05) to be infected with any STI at intake. Men partnered with teens were younger and had significantly more sexual partners per year sexually active, shorter relationship length, and shorter length of monogamy with the index girls. They were more likely to report that it was "really important" for the teen to have their baby (P = 0.04) and were slightly more likely to be the father of her children (P = 0.17). Young age independently predicted STI infection in men.

CONCLUSIONS

Although all women had an STI at intake, important differences were noted among the male partners of teens versus adults. Clinicians with similar populations may use this data to understand the characteristics of male partners of teens with STIs, in order to more effectively counsel adult and teen women on partner notification, treatment and STI prevention.
