Background: Though one-quarter of new US HIV cases occur in women, little is known about where women meet sexual partners or how meeting venue may be associated with perceptions of a partner's HIV risk.
Methods: We used baseline data from HPTN064, a community-based longitudinal cohort of women from ten US communities with a high prevalence of poverty and HIV. Eligibility required having >1 individual or sexual partner risk characteristic.Using audio computer-assisted-self-interviews, women reported where they met each of their last three male sexual partners and answered questions “as best as they knew” about each partner's risk characteristics. Venues were categorized into four groups used in venue-based research:
1) Formal (e.g., non-social with regular return patterns (e.g., work);
2) Public (e.g., bar/nightclub),
3) Private (e.g., homes);
4) Virtual (e.g. internet).
Bivariate logistic regression assessed the association between partner characteristics reported by participants and venues. Robust standard errors were used to account for within-subject correlation of repeated outcomes.
Results: 2099 women (86% Black, 38% < HS education and 45% household income ≤$10K/year) participated. Women reported where they met 3,979 partners: 51% from Public, 30% Private, 17% Formal, and 3% Internet venues. Compared to partners from Formal or Private venues, more partners from Public and Virtual venues were reported as having: HIV-positive or unknown serostatus, concurrent partners (CPs), multiple or an unknown number of CPs, and male CPs or CPs of unknown gender (Table 1).

[Venues for Meeting Sex Partners & Partner HIV Risk]


Conclusion: Women in HPTN 064 reported relatively high proportions of sexual partners with HIV risk characteristics across venue types; partners met at Public and Virtual venues were generally riskier compared with those from Private or Formal venues. A low proportion of these women met partners online. These findings can inform structural interventions and HIV prevention efforts for women.
