Prior to a mission, teachers review content and introduce students to the sim interfaces. During the mission students analyze data concerning demographics, symptoms and patient histories for a…

Although early sexual initiation has been linked to negative outcomes, it is unknown whether these effects are causal. In this study, we use propensity score methods to estimate the causal effect of early sexual initiation on young adult sexual risk behaviors and health outcomes using data from the National Longitudinal Study of Adolescent to…

The Youth Risk Behavior Survey (YRBS) is an epidemiologic surveillance system that was established by the U.S. Centers for Disease Control and Prevention (CDC) to help monitor the prevalence of behaviors that not only influence youth health, but also put youth at risk for the most significant health and social problems that can occur during…

In the United States, 70.8% of all deaths among youth and young adults aged 10-24 years result from only four causes: motor-vehicle crashes (32.3%), other unintentional injuries (11.7%), homicide (15.1%), and suicide (11.7%). Substantial morbidity and social problems also result from the approximately 870,000 pregnancies that occur each year among…
