survey conducted by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of health-risk youth behaviors. After accounting for age, what are the key factors that lead youth to engage in early sexual activity? Does physical attractiveness explain early interests? Do these kids have too much leisure time?
