Background: Feminine hygiene products (FHPs) are personal care products widely used by women. A few studies have detected some volatile organic compounds (VOCs) in FHPs, but no previous epidemiological studies have linked use of these products to human exposure to VOCs using biomarkers. Therefore, we evaluated whether the use of FHPs was associated with VOC exposures among reproductive-aged women in the United States. Materials and Methods: Data on 2432 women aged 20-49 years from National Health and Nutrition Examination Survey 2001-2004 were utilized. Self-reported use of feminine products (tampons, sanitary napkins, vaginal douches, sprays, powders, wipes/towelettes, and other products) was obtained from questionnaires. Survey-weighted linear regression models were used to estimate percent changes in VOC whole blood concentrations and 95% confidence intervals (CIs). Results: Black women had significantly more use of vaginal douching and significantly higher whole blood concentrations of 1,4-dichlorobenzene (DCB) ( p  < 0.0001). After adjusting for confounders, we observed a dose-response relationship between the frequency of vaginal douching in the past 6 months and 1,4-DCB concentrations. Compared with never users, women with occasional use (≤1 time/month) of vaginal douching had 18% (95% CI: -12% to 59%) higher concentrations, and those with frequent use (≥2 time/month) had 81% (95% CI: 2% to 221%) higher concentrations of 1,4-DCB ( p for trend = 0.04). Use of feminine powder in the past month was significantly associated with 36% (95% CI: 0.4% to 83%) higher concentrations of ethylbenzene. Conclusions: Our findings suggest that differences in whole blood VOC concentrations might be explained by feminine hygiene practices. The presence of environmental chemicals in FHPs warrants further examination.

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.

Background: Vaginal douching is associated with adverse reproductive health outcomes, yet both health providers and women are often poorly informed about details of this practice., Methods: We searched the English language articles in the MEDLINE database (1965-March 2004) to describe vaginal douching products, policies of professional organizations, predictors of douching practice, douching methods used, timing of use, and motivation. A key report was obtained from the Food and Drug Administration (FDA) via the Freedom of Information Act. Additional product information was obtained from manufacturers. Primary key terms for the literature search included (vagina OR vaginal) and (douche OR douching). Health effects of douching are reviewed briefly; personal practices and public policies are highlighted., Results: From the literature search, we identified 432 papers, of which 150 were reviewed in detail. Contrary to the assumptions of many health professionals, douching products are only loosely regulated by the FDA. Few professional organizations have clearly stated policy statements regarding douching. In the United States, the prevalence of douching varies considerably by race (more common among African Americans) and age cohort (more common in women born earlier). Internationally, vaginal douching is common in some cultures and is rare in others. Opinions of mothers, peers, and health professionals, in addition to marketing of commercial products, affect douching behavior., Conclusions: Regulation of vaginal douching products and public education efforts on douching behavior need to be reassessed. Because of the preponderance of evidence that suggests an association between vaginal douching and adverse reproductive health outcomes, professional and public health associations should consider educational and policy activities to discourage women from douching.
