In this book, we present research from the Curacao "Global School-based Student Health Survey" (GSHS). The World Health Organization (WHO) and United States "Centers for Disease Control and Prevention (CDC)" in their collaboration around this survey help countries to assess ten behavioural risk and protective factors, including alcohol use, dietary behaviours, drug use, hygiene, mental health, physical activity, protective factors, sexual behaviours, tobacco use, violence and unintentional injury among adolescents. In the survey, a self-administered questionnaire is used to obtain data on young people’s health behaviour and protective factors related to the leading causes of morbidity and mortality among children and adults worldwide. We hope that the results from this survey in Curacao will inform stakeholders of the importance of a healthy school environment, for setting priorities, establishing programmes and advocating for school and youth health programmes and related policies.
