Project S.A.F.E. Randomized, controlled trialRandomized, controlled trial - behavioral/cognitive intervention to reduce STD recurrence STD recurrence - high-risk minority women (active STD) - San Antonio, Texas (1991-1995) Significantly reduced STD reinfection at 6 and 12 months and cumulatively by reducing high-risk sexual behaviorSignificantly reduced STD reinfection at 6 and 12 months and cumulatively by reducing high-risk sexual behavior Shain et al.

Procedure 477 Women with complete data477 Women with complete data Information about sexual partners (up to 5) at each time point (total 893 partners)Information about sexual partners (up to 5) at each time point (total 893 partners) We identified “Players”: men having sex with more than one participant in our study by matching his initials, age, ethnicity, & other characteristicsWe identified “Players”: men having sex with more than one participant in our study by matching his initials, age, ethnicity, & other characteristics Analysis: chi-square, logistic regressionAnalysis: chi-square, logistic regression “Players” is the term used in the community

Players vs. Others: Infection Rates During 1-Year Follow-Up OR = 3.23 (CI 1.72-6.06) p <.01 Overall Infection Rate = 21.6 %

Unsafe Sex: Never uses condoms in casual sexNever uses condoms in casual sexand/or High number of unprotected actsHigh number of unprotected acts (5+ in last 3 months) coupled with problematic condom use

Problematic Condom Use: Condom use with: Incomplete coverage of the penisIncomplete coverage of the penis Condom slippageCondom slippage Condom breakageCondom breakage Other reported problemsOther reported problems (e.g. stuck inside her)

WAS THERE AN INTERVENTION EFFECT?

Study vs. Control Women: Partnering with Players during One-Year Follow-Up OR = 0.61 (CI 0.40-0.96) p =.034
16
Intervention Results: Women Infected with Gonorrhea and/or Chlamydia, 1-Year Follow-Up OR = 1.63 (CI 1.05-2.53) p =.03 Shain et al. NEJM 1999; 340:93
