Sport has been identified by the World Health Organization as an underutilized yet important contributor to global physical activity, by UNESCO as a fundamental right, and by the United Nations as a promising driver for gender equity through improved long-term health of women and girls. Although sport-based interventions have been popularized to advance educational, social, and political development globally, little attention has been given to its impacts on health outcomes among women and girls. We undertook a scoping review of research on sport-based interventions for health among women and girls to summarize current research approaches and findings. PRISMA scoping review guidelines were observed. Online databases (PubMed, PsycINFO, Web of Science) were used to identify peer-reviewed records published through August 2022. The interventions identified (n = 4) targeted health outcomes such as gender-based violence, HIV prevention, reproductive health, and child marriage. Based on our review, we recommend four key opportunities to advance the field of sport-based interventions in addressing health equity among women and girls. In addition, we highlight promising future research directions to broaden sport engagement of women and girls, improve long-term health, and build capacity toward health equity.
