On May 1, 2002, over 130 program managers, policymakers, service providers, and trainers participated in a day-long Technical Update, hosted by the USAID Interagency Gender Working Group (IGWG) with the Center for Health and Gender Equity (CHANGE). This summary of the Technical Update presents survey information and recent data used to define gender-based violence (GBV) and its negative impact on reproductive health outcomes. It also examines the role of organizations that work on GBV and field-based projects that address GBV through community mobilization and behavior change communication campaigns.
