Prevalence and associated risk factors of bacterial vaginosis among women of reproductive age living with, and without HIV in Lagos, Nigeria

To determine risk factors for incident bacterial vaginosis (BV) in young Thai women. Prospective data from a cohort of 1522 women aged 18 to 35 years, who were enrolled in a study of hormonal contraception and HIV acquisition, were used to evaluate potential risk factors for BV, as diagnosed by Amsel criteria. The median prevalence of BV from 3 to 24 months of follow-up visits was 2.5%. The BV incidence was 10.0 per 100-woman years. Statistically significant factors in multivariable analysis were sex during menstruation [hazard ratio (HR), 1.80; 95% CI, 1.11-2.92], male partners having sex with other women (HR, 2.3; 95% CI, 1.45-2.98), cigarette smoking (HR, 1.79; 95% CI, 1.08-2.98), and trichomoniasis (HR, 15.68; 95% CI, 4.95-49.68). Intravaginal practices were not associated with incident BV in unadjusted or adjusted analysis. This study supports the association between sexual behaviors and the incident BV. Failure to detect an association between intravaginal practices and incident BV warrants further studies in high-risk populations or in women with a higher prevalence of intravaginal practices.

To determine the prevalence of and risk factors for bacterial vaginosis. A cross-sectional study of women aged 14-54 years attending 18 primary healthcare units in Botucatu, Brazil, for cervical screening was undertaken between September 1, 2012, and January 31, 2013. Data on sociodemographics, sexual behavior, and medical history were obtained by interview. Vaginal swabs were taken to classify the vaginal flora according to the Nugent scoring system. Candida sp. hyphae and infection by Trichomonas vaginalis were also evaluated by microscopy and culture, respectively. Stepwise logistic regression analysis was performed to identify risk factors independently associated with bacterial vaginosis. Among 1519 women included in analyses, 457 (30.1%) had bacterial vaginosis. Variables independently associated with bacterial vaginosis were a single marital status (OR 1.4; 95%CI 1.1-1.8), partner infidelity (OR 1.5; 95%CI 1.2-1.9), abnormal discharge in the previous year (OR 1.5; 95%CI 1.2-2.0), and concurrent trichomoniasis (OR 4.1; 95%CI 1.5-11.5). Current use of hormonal contraception (OR 0.7; 95%CI 0.5-0.9), luteal phase of menstrual cycle (OR 0.8; 95%CI 0.6-0.9), higher income (OR 0.8; 95%CI 0.6-0.9), and vaginal candidiasis (OR 0.5; 95%CI 0.3-0.9) all had protective effects. The prevalence of bacterial vaginosis in the study population is high. The epidemiological data provide evidence of the sexual transmissibility of bacterial vaginosis.

No larger population-based study of bacterial vaginosis in pregnancy has previously been available. The objective of this study was to examine risk factors for bacterial vaginosis in pregnancy. From a prospective population-based cohort of 3,596 eligible pregnant women, 2,927 (81.4%) completed the study. Women were asked to participate in this study at their first prenatal visit at 17 gestational weeks (range 7 + 3 - 24 + 0). Samples from the genital tract were taken at enrollment. Bacterial vaginosis was determined by Amsel's clinical criteria (3 out of 4: pH > 4.5, homogenous discharge, clue cells, and positive amine test). Data were collected from three questionnaires completed during the second and third trimesters and correlated with the diagnosis of bacterial vaginosis. Crude and adjusted relative risks (reproductive, medical, behavioral, sexual, and sociodemographic factors) were computed. At enrollment, bacterial vaginosis was diagnosed in 13.7% of Danish pregnant women. Significant risk factors for bacterial vaginosis were: daily coitus (adjusted relative risk 2.09 [1.43-3.04]), being single (1.76 [1.21-2.56]), smoking more than 10 cigarettes daily at conception (1.59 [1.29-1.93]), previous genital infection with Chlamydia trachomatis or Neisseria gonorrhoeae (1.39 [1.07-1.79]), and consuming 2 or more drinks per week (1.33 [1.02-1.74]) after control for confounding factors. In pregnancy, women who have daily coitus, are single, smokers, with a previous sexually transmitted disease, or with high alcohol consumption in pregnancy are at increased risk for bacterial vaginosis. Information on these risk factors may be important when planning preventive and treatment strategies of bacterial vaginosis in pregnancy.

Background: Bacterial vaginosis (BV) is the most common vaginal infection in women of reproductive age and increases the risk of acquiring human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs). Data regarding the association between sexual activity and BV acquisition is contradictory. Thus, tracking the prevalence and associated risk factors of BV among female sex workers (FSWs) is necessary to improve our understanding and control of STDs and the HIV epidemic. Methods: The subjects of this study were FSWs in Surakarta. This study adopted a cross-sectional design, and diagnosis was established using Amsel criteria. Interviews were conducted using questionnaires to collect data of risk factors, including demographic factors (age, education level, daily income, marital status, location of sex), sociologic factors (age of first intercourse; age of first FSW encounter; duration of work as an FSW; number of clients/day; condom, contraceptive, and vaginal douching use; violence experienced as an FSW; smoking habits; alcohol consumption; and drug use), and knowledge factors (knowledge of STDs and HIV). Statistical analysis was performed by using bivariate analysis. Results: We interviewed 175 FSWs with an average age of 40.66 years. BV was detected in 28 subjects (16%). Risk factors associated with BV include alcohol (p = 0.022) and drug use (p = 0.022). Conclusion: Other than routine screening for STDs and HIV, FSWs should be encouraged to participate in prevention programs aiming to regulate alcohol and drug use to decrease the incidence of BV infection.

Prevalence and risk factors of bacterial vaginosis during the first trimester of pregnancy in a large French population-based study

The aim of this study was to estimate the risk factors of bacterial vaginosis (BV) among rural married women of childbearing age in Anhui Province of China. A cross-sectional study was conducted and the method of stratified cluster sampling was used to identify a sample of 53,652 married women aged 18-49 years. All women were asked to complete an interviewer-administered standardized questionnaire, covering sociodemographic characteristics, history of menstruation, marriage and procreation, sexual life, personal hygienic behaviors, and reproductive tract infections (RTIs) knowledge, followed by the gynecological examination and laboratory inspection. A total of 53,286 married women aged 18-49 years were included in this analysis. The prevalence of BV was 11.99 % (6,391/53,286). Risk factors for BV included the minority nationality, women's lower education levels, husband's elder age, over 35 days of menstrual cycle, less than 3 days of menstruation, dysmenorrhea, usage of an intrauterine device (IUD), lack of RTIs knowledge, higher frequency of washing genitals before having sex with husband and changing underwear, lower frequency of sexual intercourse per month, and suffering from other RTIs. The results suggest that BV can be affected by many factors among rural married women of reproductive age, so comprehensive, scheduled programs at healthcare educations should be provided for women in order to prevent BV.

The aim of this study was to identify the incidence and risk factors of bacterial vaginosis among pregnant women. Prospective data from a cohort of 668 pregnant women were used to identify potential risk factors for bacterial vaginosis during pregnancy by Cox proportional hazards regression. A total of 204 incident cases of bacterial vaginosis were diagnosed in 274.8 woman-years of follow-up. The bacterial vaginosis incidence rate was 0.74 per 1 woman-year and median prevalence during follow-up was 15.6%. In the adjusted model, changing underwear nearly everyday, miscarriage history, urinary tract infection during follow-up, husbands' education level, and concurrent trichomoniasis and candidiasis remained significantly associated with bacterial vaginosis (adjusted hazard ratio and 95% confidence interval were 1.87 [1.26-2.77]; 2.96 [1.96-4.47]; 2.41 [1.05-5.49]; 0.50 [0.32-0.77]; 1.82 [1.02-3.25]; 1.88 [1.30-2.70], respectively). Bacterial vaginosis during pregnancy can be affected by many factors, and some are indirectly acting factors. Further prospective studies that include a larger sample size and more information on the development of bacterial vaginosis are needed.

Background: A number of sexual and social risk factors for bacterial vaginosis (BV) have been identified. However, many previous studies have used small numbers of patients, or highly selected or...

Pregnancy-specific association of vitamin D deficiency and bacterial vaginosis

To determine risk factors for bacterial vaginosis (BV) among women working in the bars and hotels in Moshi, Northern Tanzania. Severe disturbances of vaginal flora or BV were detected in 70/268 (26.1%) women (95% confidence interval (CI): 20.8%-31.4%). In multivariate analyses, religion was the only socio-demographic characteristic that remained significantly associated with BV. Other independent predictors of BV were Trichomonas vaginalis (adjusted odds ratio (OR)=2.7, 95% CI: 1.4-5.3), Chlamydia trachomatis (adjusted OR=3.5, 95% CI: 1.2-10.6), syphilis (adjusted OR=7.1, 95% CI: 41.1-4.7) and herpes simplex virus type 2 (HSV-2) infection (adjusted OR=1.8, 95% CI: 1.0-3.3). Bacterial vaginosis (BV) was the common cause of genital symptoms in the study population. Since sexually transmitted diseases (STDs) were strongly associated with BV, control of STDs and BV should be given the highest priority in this population.

Prevalence and risk factors for bacterial vaginosis and cervicitis among 511 female workers attending gynecological examination in Changchun, China

Background: The sustenance of reproductive potential of patients seeking contraceptive options is essential. The risk of bacterial vaginosis is increased by the choice of contraceptive options, which may affect postcontraception fertility. Objective: To determine the prevalence and risk factors of bacterial vaginosis in a cohort of women seeking child spacing services. Materials and Methods: A cross-sectional prospective study of women seeking fertility regulation services was conducted in a tertiary health facility in Nigeria between March and September 2014. Interviews were conducted to collect data on sociodemographic characteristics, characteristics of vaginal discharge, and sexual practices engaged by these women. Bacterial vaginosis was diagnosed using the Amsel criteria. Odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated to assess the predisposing factors. Results: One-hundred seventy-eight clients were recruited. Bacterial vaginosis was noted in 7.87% of these women. Patients had increased risk of bacterial vaginosis when they were of low socioeconomic class (OR 8.17; 95% CI 2.30–29.81), used vaginal drying agents (OR 9.70; 95% CI 2.35–46.15), had an early sexual debut (OR 9.56; 95% CI 2 54–38.92), a history of previous sexually transmitted infections (OR 21.39; 95% CI 4.99–105.30), and practiced vaginal douching (OR 19.23; 95% CI 3.82–130.43). Conclusion: The prevalence of bacterial vaginosis in this cohort raises the need for a high index of clinical suspicion in patients seeking fertility regulation services in the presence of notable risk factors. Avoidance of contraceptive methods that may increase the risk of bacterial vaginosis and the need for treatment to maintain reproductive potentials is advised.

Aim To identify risk factors for bacterial vaginosis (BV) among Indonesian women. Methods This is a cross sectional study involving 492 women with age ranged 15-50 years. Vaginal discharge was collected. Whiff test and Nugent scoring were utilized to identify BV. Settings are Puskesmas Karawang, Pedes, Cikampek,Tempuran, Batalyon 201 Clinic Cijantung, Faculty of Medicine University of Indonesia and Cipto Mangunkusumo Hospital. Results Age of the subjects were 15-25 years old (26.8%), 26 - 40 years old (59.1%), and > 40 years old (14%). The mean age was 30.9 years. Marital status of the subjects were not-married (16.9%), married (76.4%), married more than once (6.7%). Prevalence of bacterial vaginosis in this study was 30.7% according to Nugent's score. Age > 40 years old (OR=3.15 IK 95% = 1.15-1.48) and uncircumcised couple (OR=6.25, IK 95% = 2.54 - 15.38) were independently and significantly associated with incidence of BV (p<0.05). Conclusions Prevalence of BV in this study was 30.7%. Determinant risk factors of BV were age and uncircumcised sexual partner. (Med J Indones 2010; 19:130-5) &nbsp

To determine the prevalence and risk factors associated with bacterial vaginosis (BV) among non-pregnant women of reproductive age group. A cross-sectional study among non-pregnant asymptomatic women aged 19 to 45 years, attending the gynaecological clinic at University of Ilorin Teaching Hospital, Ilorin, Nigeria. Participants were counselled and an informed consent was obtained. This was followed by vaginal swabs for microscopy, culture and sensitivity. Diagnosis of BV was by Nugent's criteria. Data analysis was by Statistical Package for Social Sciences (SPSS) version 20.0. Chi-square and Yates corrected chi-square were calculated, and p value <0.05 was significant. Among the 212 participants, prevalence of BV was 40.1%; it was common among women aged 25-34 years (50; 58.8%), the married (77; 90.6%) and those with tertiary education (39; 45.9%). The risk factors for BV were common among women with laboratory evidence of the infection, however statistically significant risk factors were the use of intrauterine device (OR 1.61, 95%CI 0.543-4.759; p0.020) and previous voluntary termination of pregnancy (OR 1.04, 95%CI 0.600-1.808; p0.047). There was high prevalence of bacterial vaginosis in the study population. Universal screening and treatment of cases may assist in lowering the associated morbidity.
