The 2015 Nevada Middle School YRBS: Clark County Analysis provides data to assess priority health-risk behaviors among middle school students in Clark County; measure progress toward achieving national health objectives for Healthy People 2020 and other program and policy indicators; and evaluate the impact of broad school and community interventions at the national, state, and local level. It is our intention that these data will be used by education and health professionals, policy makers, community members, and researchers in Clark County to improve the health of Nevada’s middle school students.
