Vaginal microbiota provide the first line of defense against urogenital infections primarily through protective actions of Lactobacillus species Perceived stress increases susceptibility to infection through several mechanisms, including suppression of immune function. We investigated whether stress was associated with deleterious changes to vaginal bacterial composition in a subsample of 572 women in the Longitudinal Study of Vaginal Flora, sampled from 1999 through 2002. Using Cox proportional hazards models, both unadjusted and adjusted for sociodemographic factors and sexual behaviors, we found that participants who exhibited a 5-unit-increase in Cohen's Perceived Stress Scale had greater risk (adjusted hazard ratio (HR) = 1.40, 95% confidence interval (CI): 1.13, 1.74) of developing molecular bacterial vaginosis (BV), a state with low Lactobacillus abundance and diverse anaerobic bacteria. A 5-unit increase in stress score was also associated with greater risks of transitioning from the L. iners-dominated community state type (26% higher) to molecular-BV (adjusted HR = 1.26, 95% CI: 1.01, 1.56) or maintaining molecular-BV from baseline (adjusted HR = 1.23, 95% CI: 1.01, 1.47). Inversely, women with baseline molecular-BV reporting a 5-unit stress increase were less likely to transition to microbiota dominated by L. crispatus, L. gasseri, or L. jensenii (adjusted HR = 0.81, 95% CI: 0.68, 0.99). These findings suggest that psychosocial stress is associated with vaginal microbiota composition, inviting a more mechanistic exploration of the relationship between psychosocial stress and molecular-BV., (© The Author(s) 2021.

Background: An increased incidence in hygiene-related urogenital infections (bacterial vaginitis, vulvovaginal candidiasis, and urinary tract) has been reported in female warfighters serving in austere environments with decreased availability of water and sanitation resources, and when personal safety outweighs concerns for hygiene. Knowledge and access to an innovative kit designed for the female warfighter to self-test, self-identify, and self-treat common urogenital symptoms is critical to force health., Purpose: The purpose of this descriptive, cross-sectional, exploratory qualitative study was to explore female warfighters': 1) confidence in seeking sex-specific health care in field and deployment environments and 2) acceptance and willingness to self-test, self-identify, and self-treat urogenital symptoms and infections., Methodological Orientation: Qualitative data for this thematic analysis were collected during administration of the Military Women's Readiness Urogenital Health Questionnaire. Participants provided open-ended comments associated with three survey questions. Braun and Clarke's inductive thematic analysis method guided the narrative analysis., Sample: Our sample included a diverse group of US Army women (USAW; n = 152) from a large, military installation., Results: Narratives and themes demonstrate USAW's desire and need for the availability of a self-test and self-treatment kit. Access, time, mission, and prevention of self-harm by quicker resolve of symptoms are cited as key reasons in support of such a kit., Conclusions and Practice Implications: Nurse practitioners (NPs) are ideally positioned to provide sex-specific educational interventions and anticipatory guidance that supports physical health, to include urogenital conditions. As urogenital self-testing becomes available for female warfighters, NPs are the model healthcare provider for educating women on their use.

Bacterial vaginosis (BV) is a common vaginal infection among women of reproductive age. Increasing evidence suggests BV may be sexually transmitted indicating a potential role for the treatment of sexual partners. If partner treatment reduces BV recurrence in women, real-world success will depend on sexual partners' willingness to accept it. However, a lack of data exists on the acceptability of partner treatment among sexual partners, and no data exists on male partners' experience of BV specifically. The aim of this study was to explore male partners' views and experience of BV and their attitudes toward associated partner treatment. A social constructionist approach informed the framework of this study. Semi structured interviews were conducted with eleven men who participated in a BV partner treatment trial. Interviews were transcribed verbatim and analysed thematically. In the absence of symptoms in themselves, BV had little impact on men beyond their concerns for their partner's health and self-esteem. Acceptance of treatment was largely a demonstration of care and support. While all participants had accepted treatment, men surmised the primary reasons other men may reject treatment as being: if they felt BV had "nothing to do with them", which was related to not wanting to be viewed as having a 'problem' and exacerbated by norms of masculinity and STI-related stigma; lack of a diagnostic test to indicate if a male "had BV"; and a casual or less established relationship. Men's attitudes to BV and partner treatment were primarily influenced by the nature of their relationships. The ambiguous aetiology of BV appears to attenuate STI related stigma and questions of infidelity., Competing Interests: The authors have declared that no competing interests exist.

Background: Intravaginal practices (IVP) (cleansing or introducing products inside the vagina for hygiene, health or to please sexual partners) are common among women with HIV. IVP increase the risk of developing bacterial Vaginosis (BV), the most common genital infection associated with transmission of sexually transmitted infections and HIV. This study tested a pilot intervention to reduce IVP and BV in HIV infected women in Zambia., Methods: One hundred twenty-eight HIV infected women engaging in IVP were randomized to two conditions: enhanced standard of care (n = 70) and experimental (n = 58) from May 1, 2013 to February 28, 2014. All participants received a brief educational counseling session on discontinuation of IVP, and those with BV, were provided with medical treatment for BV. Women in the experimental condition received an additional group-based, culturally tailored intervention. Participants completed questionnaires assessing sexual risk factors and IVP and were assessed for BV using Nugent criteria at baseline, 6 months and 12 months., Results: At 12-month, the proportion of self-reported use of IVPs decreased in the experimental condition: soap (28% vs. 47%); cloth or a rag (19% vs. 38%); and traditional medicines (22% vs. 42%) (all p < 0.05)) compared with the enhanced standard of care condition. The prevalence of BV at 6 and 12 months did not differ by study condition but averaging over study condition, prevalence of BV decreased from 64.2% at baseline to 15.6% at 6 months (p < 0.01) and to 23.6% at 12 months (p = 0.15). Using an enhanced standard of care approach and an enhanced standard of care + a group intervention, IVP and BV decreased over time, but the experimental condition had greater reduction in self-reported use of IVP., Conclusions: Future studies should address interventions in communities with high burden of IVP, BV and HIV. Interventions that could be administered during routine medical care and decrease IVP and BV are needed, and should be considered part of women's health programs., Trial Registration Number: NCT03134924 (retrospectively registered 21st April 2017).

Background: Bacterial vaginosis (BV) affects a third of women of reproductive age in the US and there is increasing evidence to suggest it may be sexually transmitted. This study aimed to extend and validate the findings of our earlier smaller qualitative study by exploring in detail women's views and experiences of the triggering factors associated with BV onset and recurrence., Methods: Women aged 20-49, who had experienced one or more symptomatic episode of BV within 6 months, were opportunistically recruited to complete a 38-item questionnaire on their experience of BV., Results: 103 women completed the questionnaire. Women were significantly more likely to report sexual than lifestyle factors triggered BV onset and recurrence (p<0.001). The top 3 factors women attributed to both BV onset and recurrence were identical-and all sexual. They included, in order: 1) unprotected sex; 2) sex with a new male partner; and 3) sex in general. The main lifestyle factors nominated included stress, diet, menstruation and the use of feminine hygiene products. While many women felt their BV had been transmitted through sexual contact (54%) and developed as a result of sexual activity (59%), few considered BV a sexually transmitted infection (STI) (10%). Despite this 57% felt partners should also be treated for BV., Conclusion: These data concur with our earlier qualitative findings that women believe BV is triggered by sexual activity. While many women felt BV was sexually transmitted and supported partner treatment, they did not consider BV an STI. This contradiction is likely due to information conveyed to women based on current guidelines. In the absence of highly effective BV treatments, this study highlights the need for guidelines to indicate there is scientific uncertainty around the pathogenesis of BV and to contain clear health messages regarding the evidence for practices shown to be associated with a reduced risk of BV (i.e. consistent condom use.

Background: Bacterial vaginosis (BV) is the most common vaginal infection affecting women of childbearing age. While the aetiology and transmissibility of BV remain unclear, there is strong evidence to suggest an association between BV and sexual activity. This study explored women's views and experiences of the triggers for BV onset and factors associated with recurrence., Methods: A descriptive, social constructionist approach was chosen as the framework for the study. Thirty five women of varying sexual orientation who had experienced recurrent BV in the past five years took part in semi-structured interviews., Results: The majority of women predominantly reported sexual contact triggered the onset of BV and sexual and non-sexual factors precipitated recurrence. Recurrence was most commonly referred to in terms of a 'flare-up' of symptoms. The majority of women did not think BV was a sexually transmitted infection however many reported being informed this by their clinician. Single women who attributed BV onset to sex with casual partners were most likely to display self-blame tendencies and to consider changing their future sexual behaviour. Women who have sex with women (WSW) were more inclined to believe their partner was responsible for the transmission of or reinfection with BV and seek partner treatment or change their sexual practices., Conclusion: Findings from this study strongly suggest women believe that BV onset is associated with sexual activity, concurring with epidemiological data which increasingly suggest BV may be sexually transmitted. Exacerbating factors associated with recurrence were largely heterogeneous and may reflect the fact it is difficult to determine whether recurrence is due to persistent BV or a new infection in women. There was however evidence to suggest possible transmission and reinfection among WSW, reinforcing the need for new approaches to treatment and management strategies including male and female partner treatment trials.

Background: Bacterial vaginosis is a common vaginal infection, causing an abnormal vaginal discharge and/or odour in up to 50% of sufferers. Recurrence is common following recommended treatment. There are limited data on women's experience of bacterial vaginosis, and the impact on their self-esteem, sexual relationships and quality of life. The aim of this study was to explore the experiences and impact of recurrent bacterial vaginosis on women., Methods: A social constructionist approach was chosen as the framework for the study. Thirty five women with male and/or female partners participated in semi-structured interviews face-to-face or by telephone about their experience of recurrent bacterial vaginosis., Results: Recurrent bacterial vaginosis impacted on women to varying degrees, with some women reporting it had little impact on their lives but most reporting it had a moderate to severe impact. The degree to which it impacted on women physically, emotionally, sexually and socially often depended on the frequency of episodes and severity of symptoms. Women commonly reported that symptoms of bacterial vaginosis made them feel embarrassed, ashamed, 'dirty' and very concerned others may detect their malodour and abnormal discharge. The biggest impact of recurrent bacterial vaginosis was on women's self-esteem and sex lives, with women regularly avoiding sexual activity, in particular oral sex, as they were too embarrassed and self-conscious of their symptoms to engage in these activities. Women often felt confused about why they were experiencing recurrent bacterial vaginosis and frustrated at their lack of control over recurrence., Conclusion: Women's experience of recurrent bacterial vaginosis varied broadly and significantly in this study. Some women reported little impact on their lives but most reported a moderate to severe impact, mainly on their self-esteem and sex life. Further support and acknowledgement of these impacts are required when managing women with recurrent bacterial vaginosis.

Background: Data on risk factors of recurrent bacterial vaginosis (RBV) are still scarce. We used data from female sex workers (FSW) participating in a randomized controlled microbicide trial to examine predictors of BV recurrence., Methods: Trial's participants with at least an episode of BV which was treated and/or followed by a negative BV result and at least one subsequent visit offering BV testing were included in the analysis. Behavioural and medical data were collected monthly while laboratory testing for STI and genital tract infections were performed quarterly. The Andersen-Gill proportional hazards model was used to determine predictors of BV recurrence both in bivariate and multivariate analyses., Results: 440 women were included and the incidence rate for RBV was 20.8 recurrences/100 person-months (95% confidence interval (CI) =18.1-23.4). In the multivariate analysis controlling for the study site, recent vaginal cleansing as reported at baseline with adjusted hazard-ratio (aHR)=1.30, 95% CI = 1.02-1.64 increased the risk of BV recurrence, whereas consistent condom use (CCU) with the primary partner (aHR=0.68, 95% CI=0.49-0.93) and vaginal candidiasis (aHR=0.70, 95% CI=0.53-0.93), both treated as time-dependent variables, were associated with decreased risk of RBV., Conclusion: This study confirms the importance of counselling high-risk women with RBV about the adverse effects of vaginal cleansing and the protective effects of condom use with all types of partners for the prevention of sexually transmitted infections, including BV. More prospective studies on risk factors of BV recurrence are warranted., Trial Registration: Trial registration: NCT00153777.

Objective: The purpose of this study was to examine associations between chronic preconception psychosocial and socioeconomic stress with bacterial vaginosis (BV) during pregnancy., Study Design: Using univariate and multivariate logistic regression, childhood abuse and neglect, chronic discrimination, childhood socioeconomic status, potential confounders, and BV were assessed at 14-16 and 19-22 weeks' gestation in a cohort of 312 pregnant women., Results: Persistent BV (BV positive at both time points vs no BV at either time point) was associated with childhood sexual abuse (CSA), chronic discrimination, and lack of parental home ownership. These associations were still present after covarying for current perceived stress, socioeconomic status, and other potential confounders., Conclusion: There is evidence that BV during pregnancy is independently linked with early life psychosocial adversity, suggesting that a life-course perspective may be important in elucidating determinants of perinatal outcomes., (Copyright © 2011 Mosby, Inc.

Objective: To determine women's experience and knowledge of the 2 most common non-sexually transmitted vaginal infections, vulvovaginal candidiasis (VVC) and bacterial vaginosis (BV)., Materials and Methods: An online omnibus was conducted on 6,010 women aged 16 to 55 years to determine the incidence and awareness of VVC and BV in Europe (France, Germany, the Netherlands, Sweden, and the United Kingdom) and the United States, followed by an in-depth questionnaire on 1,945 women about experience and attitudes to VVC and BV., Results: Almost all (97%) of the women who took part stated that they were aware of VVC and 44% reported having had VVC, whereas only 30% of women had heard of BV and only 9% thought they had experienced it. There was confusion between symptoms specifically related to each condition, and women thought they were caused by poor hygiene, ill health, or a sexually transmitted infection, with antibiotic use cited as a cause for VVC only. Diagnosis was generally by a health care professional, but there was also considerable self-diagnosis in countries where an over-the-counter treatment was available for VVC. Rates of reported examination and testing by the health care provider varied by country, with high rates in Germany and low rates in the United Kingdom., Conclusions: Women seem very aware and knowledgeable about VVC, but awareness of BV is low with self-reported incidence considerably less than prevalence rates, suggesting misdiagnosis. Increased education and better diagnosis of these 2 conditions is needed to remove the stigma and taboo, especially for BV, and to ensure correct diagnosis with appropriate treatment.

Objective: To determine whether menstrual abnormalities, multiple personal behaviors and some contraceptive methods, all of which have been described as potential causes of single episodes of bacterial vaginosis (BV), are associated with recurrent bacterial vaginosis (RBV)., Study Design: This was a retrospective, case-controlled study performed in an urban setting. Women with RBV and matched controls were mailed a survey that included multiple questions about potential risk factors for BV. Four-to-one matching of age groups was performed, with 28 RBV cases matched to 112 controls., Results: Among multiple possible predisposing factors, only African American ethnicity (p < 0.001) and > 1 male sex partner in the previous 2 years (p = 0.007) were strongly associated with RBV. Abnormal uterine bleeding, frequent intercourse without a condom or withdrawal, anal intercourse, menstrual hygiene product use, tub baths, back-to-front wiping after using the toilet, smoking, choice of contraceptive method (including condoms, the combination oral contraceptive, injectable medroxyprogesterone acetate or an intrauterine device) and douching were not associated with RBV., Conclusion: Providers should counsel women with RBV to minimize their number of male sex partners. There are few data to support the recommendation of other behavioral changes.

Racial disparity in preterm birth is one of the most salient, yet least well-understood health disparities in the United States. The preterm birth disparity may be due to differences in how women experience their racial identity in light of neighborhood factors, psychosocial stress, or the prevalence of or response to genital tract infections such as bacterial vaginosis (BV). The latest research emphasizes a need to explore all these factors simultaneously. This cross-sectional study of parous women in King County, Washington, USA investigated the effects of household income, psychosocial stress, and neighborhood socioeconomic characteristics on risk of BV after accounting for known individual-level risk factors. Relevant demographic, socioeconomic, and medical data were linked to U.S. census socioeconomic data by geocoding subjects' residential addresses. It was found that having a low income was significantly associated with an increased prevalence of BV among African American but not White American women. A higher number of stressful life events was significantly associated with higher BV prevalence among both African American and White American women. However, perceived stress was not related to BV risk among either group of women. Among White American women, neighborhood socioeconomic status (SES) was univariately associated with increased BV prevalence by principal components analysis, but was no longer significant after adjusting for individual-level risk factors. No neighborhood SES effects were observed for African American women. These results suggest that both the effects of individual- and neighborhood-level risk factors for BV may differ importantly by racial group, and stressful life events may have physiological effects independent of perceived stress.

Objectives: To determine whether stress is associated with risk of bacterial vaginosis (BV) in pregnant women., Design: Prospective cohort study., Setting: The prenatal care clinics at the University of North Carolina. The residents' clinic sees mostly government-insured and uninsured women, and the physicians' clinic sees mostly those with private health insurance., Population: A total of 897 women gave samples for BV analysis. Study participants were 22% African-American, 68% white; 24% unmarried and 44% nulliparous. More than half had completed college., Methods: Women completed two questionnaires and two interviews reporting stress and psychological aspects of their lives. Measurement scales included the Sarason life events questionnaire, the Cohen perceived stress scale, Spielberger state-trait anxiety, the John Henryism coping style and the Medical Outcomes Study social support inventory. Two stress hormones, corticotrophin-releasing hormone and cortisol, were also measured., Main Outcome Measures: BV at 15-19 and 24-29 weeks of gestation was diagnosed by Gram's stain., Results: Women in the highest quartile of stress measures, particularly state anxiety (OR=2.0, 95% CI 1.2-3.3), perceived stress (OR=2.4, 95% CI 1.5-3.9) and total life events (OR=2.0, 95% CI 1.3-3.2), had the highest risk of BV. Adjustment for confounders, especially age, race, and income, reduced these associations (state anxiety: OR=1.3, 95% CI 0.7-2.4; perceived stress: OR=1.4, 95% CI 0.8-2.5; total life events: OR=1.3, 95% CI 0.7-2.4). No clear pattern of association was seen between stress hormones and BV., Conclusions: Few associations between stress and BV were seen after adjustment for confounders.

Objective: The purpose of this study was to assess the association of psychosocial stress with bacterial vaginosis in a longitudinal sample of nonpregnant women., Study Design: A 1-year prospective longitudinal design was used. Nonpregnant women (n = 3614) aged 15 to 44 years were recruited at routine health care visits. Assessments were conducted quarterly for 1 year and included a standardized pelvic examination, an assessment of clinical symptoms, and an extensive self-report interview., Results: Psychosocial stress was associated with overall prevalence of (adjusted odds ratio, 1.10; 95% CI, 1.01-1.20) and an increased incidence of (adjusted odds ratio, 1.29; 95% CI, 1.12-1.48) bacterial vaginosis. The association between stress and bacterial vaginosis incidence was not changed appreciably by the control for behavioral and demographic characteristics and was magnified (odds ratio, 2.05; 95% CI, 1.15-3.66) in a case-crossover analysis., Conclusion: Increased psychosocial stress is associated with greater bacterial vaginosis prevalence and incidence independent of other risk factors.

The authors investigated the role of stress and cortisol with patients having preterm labor (PTL) and preterm birth (PTB). The relationships of maternal cortisol, perceived stress, fetal fibronectin (fFN), and genitourinary infections to PTL and PTB were studied. A prospective, longitudinal, observational study (n = 78) was conducted in a private practice in central Texas. Subjects had 4 blood draws for cortisol measurements grouped by 15-19, 20-22, 23-26, 27-30, and 31-35 weeks of gestation. Subjects had 2 vaginal swabs forfFN, chlamydia, and bacterial vaginosis screens at 23-26 and 27-30 weeks with assessment of psychosocial stress at 23-26 and 31-35 weeks. Statistical analysis was by analysis of variance, Pearson correlations, Fisher exact test, and logistic regression. There were no significant differences between the PTB, PTL, and term groups on cortisol levels at any of the gestational periods. Cortisol concentrations at any gestational stage did not correlate with gestational age at birth. A relationship of cortisol to race was observed when comparing Caucasians to other ethnic groups. A correlation (r = 0.42, P < 0.001) between the change in Perceived Stress Scale (PSS) score and gestational age was observed. The greater the decrease in PSS scores, the longer was the gestational age. A significant increase in cortisol at 19-21 weeks (P < 0.04), 23-26 weeks (P < 0.05), and 31-35 weeks (P < 0.01) was observed in patients having genitourinary infection. PTL was also significantly increased in subjects having positive genitourinary infections at either 23-26 weeks or 27-30 weeks (P < 0.01). The sensitivity of fFN to predict PTL collected at 27-30 weeks was 40%, specificity 86%, positive predictive value 55%, and negative predictive value 83%. These results indicate that cortisol is a poor predictor of either PTL or PTB. A decrease in perceived stress during the 2nd trimester was associated with an increase in length of gestation, suggesting the possibility of stress reduction as an appropriate intervention for lengthening gestational age.
