Abstract

Objective We used validated sensitive and specific questions associated with clinically confirmed diagnoses of unexplained vulvar pain (vulvodynia) to compare the cumulative incidence of vulvar pain and prevalence of care-seeking behavior in Boston metropolitan area (BMA) and in Minneapolis/Saint Paul metropolitan area (MSP) from 2001 through 2005 using census-based data, and 2010 through 2012, using outpatient community-clinic data, respectively.Study design We received self-administered questionnaires from 5440 women in BMA and 13,681 in MSP, 18-40 years of age, describing their history of vulvar burning or pain on contact that persisted >3 months that limited/prevented intercourse.Results By age 40 years, 7-8% in BMA and MSP reported vulvar pain consistent with vulvodynia. Women of Hispanic origin compared to whites were 1.4 times more likely to develop vulvar pain symptoms (95% confidence interval, 1.1-1.8). Many women in MSP (48%) and BMA (30%) never sought treatment, and >50% who sought care with known health care access received no diagnosis.Conclusion Using identical screening methods, we report high prevalence of vulvar pain in 2 geographic regions, and that access to health care does not increase the likelihood of seeking care for chronic vulvar pain.

    The self-administered screening questions for vulvar pain have high sensitivity (83%) and specificity (94-95%) compared with a clinical diagnosis of vulvodynia.

    “we previously reported that women reporting pain on contact for a period of three months or longer that limited or prevented intercourse was associated with an 83% sensitivity and 94% specificity for meeting a true diagnosis of vulvodynia based on the gold standard of a clinical examination to rule out other known causes of vulvar pain.5”

    Study design and conductreasoning

    Because there was no clinical examination, some women classified as having symptoms consistent with vulvodynia may not meet clinical diagnostic criteria, so estimates likely include some misclassification.

    “Without an actual clinical examination, we cannot be sure that those classified as having symptoms consistent with vulvodynia would in fact meet the existing or future clinically-confirmed diagnostic criteria for this condition. Thus, our estimates of age-specific risk and cumulative incidence across two geographical regions will likely include some degree of misclassification.”

    Women accurately reported their care-seeking behavior and whether they received a diagnosis.

    Non-respondents are similar to respondents on characteristics other than age that are relevant to vulvar pain.

    “In both the BMA and the MSP sample, respondents and non-respondents were comparable by age”

  • Approximately 40% of women with vulvodynia refrain altogether from seeking help.

    “Approximately 40 % of women with vulvodynia refrain altogether from seeking help, in many cases because of stigma associated with the conditions [7, 19, 20]”

    From A feasibility trial of online Acceptance and Commitment Therapy for women with provoked vestibulodynia (2023) · cites this paper as [7]

    The Results (page unavailable) report that 48% of women with symptoms consistent with vulvodynia in the MSP sample and 30% in the BMA sample never sought treatment, broadly supporting the approximate 40% figure. The Comment (page unavailable) suggests stigma as a possible explanation but says reasons for not seeking care may be multifactorial; it does not establish that stigma explains many cases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
