Investigating site-level longitudinal effects of population health interventions: Gay-Straight Alliances and school safety
Abstract There is limited research on evaluating nonrandomized population health interventions. We aimed to introduce a new approach for assessing site-level longitudinal effects of population health interventions (SLEPHI) by innovatively applying multiple group multilevel (MG-ML) modeling to repeated cycles of cross-sectional data collected from different individuals of the same sites at different times, a design […]
Population-level sexual behaviours in adolescent girls before and after introduction of the human papillomavirus vaccine (2003–2013)
Abstract The human papillomavirus (HPV) vaccine is delivered widely through school-based immunization programs. Some groups have expressed concern that HPV vaccination programs will result in an increase in sexual risk-taking behaviours among adolescents.

Although knowledge of trends in PDV victimization can help guide programming and health policies, little research has examined whether the prevalence of PDV victimization has increased, decreased, or remained stable over time among non-U.S.-based samples of youth. In addition, few studies have […]

Assessing the impacts and outcomes of youth driven mental health promotion: A mixed-methods assessment of the Social Networking Action for Resilience study
Abstract Mental health challenges are the leading health issue facing youth globally. To better respond to this health challenge, experts advocate for a population health approach inclusive of mental health promotion; yet this area remains underdeveloped. Further, while there is growing emphasis on youth-engaged research and intervention design, evidence of the outcomes and impacts are […]
Abstract Background: Transgender (trans) youth who identify outside the gender binary are a growing subpopulation. In this article, we document differences in access to gender-affirming health care between binary and non-binary identified trans youth and explore ways of meeting the health needs of non-binary youth within primary care settings. Methods: The Canadian Trans Youth Health Survey is […]

The survey included somewhat different questions for younger (14-18 years) and older (19-25 years) trans youth about a wide range of life experiences and behaviours that influence young people’s health. This report is focused […]
