Objective To assess whether the risk of vulvodynia is associated with previous use of oral contraceptives ( OCs). Design Longitudinal population-based study. Setting Four counties in south-east Michigan, USA. Population A population-based sample of women, aged 18 years and older, enrolled using random-digit dialling. Methods Enrolled women completed surveys that included information on demographic characteristics, health status, current symptoms, past and present OC use, and a validated screen for vulvodynia. The temporal relationship between OC use and subsequent symptoms of vulvodynia was assessed using Cox regression, with OC exposure modelled as a time-varying covariate. Main outcome measure Vulvodynia, as determined by validated screen. Results Women aged <50 years who provided data on OC use, completed all questions required for the vulvodynia screen, and had first sexual intercourse prior to the onset of vulvodynia symptoms were eligible ( n = 906). Of these, 71.2% ( n = 645) had used OCs. The vulvodynia screen was positive in 8.2% ( n = 74) for current vulvodynia and in 20.8% ( n = 188) for past vulvodynia. Although crude cross-tabulation suggested that women with current or past vulvodynia were less likely to have been exposed to OCs prior to the onset of pain (60.7%), compared with those without this disorder (69.3%), the Cox regression analysis identified no association between vulvodynia and previous OC use ( HR 1.08, 95% CI 0.81-1.43, P = 0.60). This null finding persisted after controlling for ethnicity, marital status, educational level, duration of use, and age at first OC use. Conclusion For women aged <50 years of age, OC use did not increase the risk of subsequent vulvodynia. [ABSTRACT FROM AUTHOR]

Background: Risk factors for vulvodynia continue to be elusive. We evaluated the association between past environmental exposures and the presence of vulvodynia., Materials and Methods: The history of 28 lifetime environmental exposures was queried in the longitudinal population-based Woman-to-Woman Health Study on the 24-month follow-up survey. Relationships between these and vulvodynia case status were assessed using multinomial logistic regression., Results: Overall, 1585 women completed the 24-month survey, the required covariate responses, and questions required for case status assessment. Screening positive as a vulvodynia case was associated with history of exposures to home-sprayed chemicals (insecticides, fungicides, herbicides-odds ratio [OR] 2.47, 95% confidence interval [CI] 1.71-3.58, p < 0.0001), home rodent poison and mothballs (OR 1.62, 95% CI 1.25-2.09, p < 0.001), working with solvents and paints (OR 2.49, 95% CI 1.68-3.70, p < 0.0001), working as a housekeeper/maid (OR 2.07, 95% CI 1.42-3.00, p < 0.0001), working as a manicurist/hairdresser (OR 2.00, 95% CI 1.14-3.53, p < 0.05), and working at a dry cleaning facility (OR 2.13, 95% CI 1.08-4.19, p < 0.05). When classified into nine individual environmental exposure categories and all included in the same model, significant associations remained for four categories (home-sprayed chemicals, home rodent poison or mothballs, paints and solvents, and working as a housekeeper)., Conclusions: This preliminary evaluation suggests a positive association between vulvodynia and the reported history of exposures to a number of household and work-related environmental toxins. Further investigation of timing and dose of environmental exposures, relationship to clinical course, and treatment outcomes is warranted.

Objective: The objective of the study was to determine the prevalence and characteristics of vulvodynia among women in southeast Michigan. Study design: A population-based study of adult women was conducted, using telephone recruitment and completion of a self-administered survey. Weighted estimates of vulvodynia prevalence and characteristics were determined. Results: Over a year, 2542 women were recruited and 2269 (89.3%) completed the self-administered survey. The weighted prevalence of vulvodynia was 8.3% (95% confidence interval, 7.0–9.8) or approximately 101,000 women in the targeted population. Prevalence remained stable through age 70 years and declined thereafter. Among sexually active women, the prevalence was similar at all ages. Of 208 women meeting vulvodynia criteria, 101 (48.6%) had sought treatment, and only 3 (1.4%) had been diagnosed with vulvodynia (unweighted values). Previous vulvodynia symptoms had resolved in 384 women (16.9%) after a mean duration of 12.5 years. Conclusion: Vulvodynia is common, although rarely diagnosed. Prevalence remains high among sexually active women of any age. [ABSTRACT FROM AUTHOR]
