Assessing Intravaginal Practices in HIV Prevention Research: Development and Validation of an Intravaginal Practices Questionnaire. ARCHIVES OF SEXUAL BEHAVIOR 2023; 52:803-808. [PMID: 36459351 PMCID: PMC11046221 DOI: 10.1007/s10508-022-02484-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 11/15/2022] [Accepted: 11/16/2022] [Indexed: 06/01/2023]
Abstract
Intravaginal practices (IVPs) refer to placing items (e.g., water, soap, commercial douches, fingers, rags) inside the vagina. IVPs have been shown to contribute to the development of bacterial vaginosis (BV) and may increase sexually transmitted infections and HIV risk. We developed the Intravaginal Practices Questionnaire (IVQ). The purpose of this study was to validate the IVQ, with the goal of establishing a consistent method of assessing IVP across studies. Women enrolled in this study (n = 180) were on average 30 years of age (SD = 8.32). Half (54%) identified as non-Hispanic, and 45% identified as Black; 41% reported lifetime IVP. Past month IVP use included commercial douches (9%), water (35%), fingers (41%), soap (21%), cloths/rags/wipes (10%), and vinegar (3%), which were placed in the vagina. No women used yogurt or herbs. An exploratory factor analysis indicated that a single-factor structure best explained the underlying constructs in participant responses in six endorsed items assessing commercial douches, water, fingers, soap, clothes/rags/ wipes, and vinegar use, suggesting that a common factor underlies these behaviors. All factor loadings were > 0.496. Cronbach's α was 0.99, suggesting that the reliability of the scale was excellent. Lastly, a total IVQ score was related to BV diagnosis (p = .007) as well as self-reported symptoms of BV (p = .034). Results illustrate that the IVQ has adequate psychometric properties. This tool may be used by public health experts and clinicians to identify IVPs that may potentially increase HIV risk.

The Vaginal Microbiome in Health and Disease-What Role Do Common Intimate Hygiene Practices Play? Microorganisms 2023; 11:microorganisms11020298. [PMID: 36838262 PMCID: PMC9959050 DOI: 10.3390/microorganisms11020298] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/17/2023] [Accepted: 01/17/2023] [Indexed: 01/25/2023] Open
Abstract
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.

Gerstl S, Lee L, Nesbitt RC, Mambula C, Sugianto H, Phiri T, Kachingwe J, Llosa AE. Cervical cancer screening coverage and its related knowledge in southern Malawi. BMC Public Health 2022; 22:295. [PMID: 35164716 PMCID: PMC8842862 DOI: 10.1186/s12889-022-12547-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 01/03/2022] [Indexed: 12/24/2022] Open
Abstract
Background Cervical cancer (CC) is the fourth most common cancer among women worldwide and Malawi has the world’s highest rate of cervical cancer related mortality. Since 2016 the National CC Control Strategy has set a screening coverage target at 80% of 25-49-year-old women. The Ministry of Health and Médecins Sans Frontières (MSF) set up a CC program in Blantyre City, as a model for urban areas, and Chiradzulu District, as a model for rural areas. This population-based survey aimed to estimate CC screening coverage and to understand why women were or were not screened. Methods A population-based survey was conducted in 2019. All resident consenting eligible women aged 25-49 years were interviewed (n = 1850) at households selected by two-stage cluster sampling. Screening and treatment coverage and facilitators and barriers to screening were calculated stratified by age, weighted for survey design. Chi square and design-based F tests were used to assess relationship between participant characteristics and screening status. Results The percentage of women ever screened for CC was highest in Blantyre at 40.2% (95% CI 35.1-45.5), 38.9% (95% CI 32.8-45.4) in Chiradzulu with supported CC screening services, and lowest in Chiradzulu without supported CC screening services at 25.4% (95% CI 19.9-31.8). Among 623 women screened, 49.9% (95% CI 44.0-55.7) reported that recommendation in the health facility was the main reason they were screened and 98.5% (95% CI 96.3-99.4) recommended CC screening to others. Among 1227 women not screened, main barriers were lack of time (26.0%, 95% CI 21.9-30.6), and lack of motivation (18.3%, 95% CI 14.1-23.3). Overall, 95.6% (95% CI 93.6-97.0) of women reported that they had some knowledge about CC. Knowledge of CC symptoms was low at 34.4% (95% CI 31.0-37.9) and 55.1% (95% CI 51.0-59.1) of participants believed themselves to be at risk of CC. Conclusion Most of the survey population had heard about CC. Despite this knowledge, fewer than half of eligible women had been screened for CC. Reasons given for not attending screening can be addressed by programs. To significantly reduce mortality due to CC in Malawi requires a comprehensive health strategy that focuses on prevention, screening and treatment.

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. AIDS Behav 2021; 25:2992-3010. [PMID: 33977356 DOI: 10.1007/s10461-021-03290-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/23/2021] [Indexed: 02/07/2023]
Abstract
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.

Exploring the Vaginal Microbiome and Intravaginal Practices in Postmenopausal Women. Nurs Res 2021; 70:405-411.

Abstract
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.

Low-cost diagnostic test for susceptible and drug-resistant tuberculosis in rural Malawi. Afr J Lab Med 2018; 7:690. [PMID: 29977794 PMCID: PMC6018377 DOI: 10.4102/ajlm.v7i1.690] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2017] [Accepted: 01/29/2018] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Rural settings where molecular tuberculosis diagnostics are not currently available need easy-to-use tests that do not require additional processing or equipment. While acid-fast bacilli (AFB) smear is the most common and often only tuberculosis diagnosis test performed in rural settings, it is labour intensive, has less-than-ideal sensitivity, and cannot assess tuberculosis drug susceptibility patterns. OBJECTIVE The objective of this study was to determine the feasibility of a multidrug-resistant (MDR) or extensively drug-resistant (XDR)-tuberculosis coloured agar-based culture test (tuberculosis CX-test), which can detect Mycobacterium tuberculosis growth and evaluate for drug susceptibility to isoniazid, rifampicin and a fluoroquinolone (i.e. ciprofloxacin) in approximately 14 days. METHOD In this study, 101 participants were enrolled who presented to a rural health clinic in central Malawi. They were suspected of having active pulmonary tuberculosis. Participants provided demographic and clinical data and submitted sputum samples for tuberculosis testing using the AFB smear and tuberculosis CX-test. RESULTS The results showed a high level of concordance between the AFB smear (12 positive) and tuberculosis CX-test (13 positive); only one sample presented discordant results, with the molecular GeneXpert MTB/RIF® test confirming the tuberculosis CX-test results. The average time to a positive tuberculosis CX-test was 10 days. Of the positive samples, the tuberculosis CX-test detected no cases of drug resistance, which was later confirmed by the GeneXpert MTB/RIF®. CONCLUSION These findings demonstrate that the tuberculosis CX-test could be a reliable low-cost diagnostic method for active pulmonary tuberculosis in high tuberculosis burden rural areas.
