The time-space permutation statistic identified 5 clusters containing 25 cases with a rate ratio of 2.27 (95% confidence interval 1.28 to 4.03). Individuals in clusters identified by the new criteria were more likely to be of Hispanic origin (61% vs 20%) and in rural areas (51% vs 12%). The space-time permutation cluster analysis is a promising tool for identification of clusters with the largest growth potential for whom interruption may prove most beneficial.

As adolescent girls and young women (AGYW) transition to adulthood, their interaction with their social context becomes a critical consideration for HIV prevention interventions. Few studies have examined what types of community groups and community spaces might be protective for AGYW HIV acquisition and related sexual behaviors. Data were obtained from HIV Prevention Trials Network 068, a longitudinal study of AGYW (age 13-20 years) in rural South Africa. Survival analyses and generalized estimating equations were used to assess whether community group membership and time spent in community spaces were associated with HIV incidence and sexual behaviors (unprotected sex, transactional sex, and having an older partner). A total of 2245 AGYW were followed up for up to 4 years. Membership in church groups [adjusted hazard ratio (aHR) 0.75, 95% confidence interval (CI) 0.53 to 0.91] and dance groups (aHR 0.89, 95% CI 0.80 to 0.98) and spending time at church (aHR 0.88, 95% CI 0.79 to 0.98) were protective for HIV infection. Conversely, spending time at taverns was associated with higher HIV incidence (aHR 1.27, 95% CI 1.15 to 1.41). Membership in church groups and spending time at a family member's home and at church were protective for all 3 sex
