The Health Behaviour in School-aged Children (HBSC) study is a continuing cross-national research project conducted in collaboration with the World Health Organization Regional Office for Europe. Its aim is to contribute new knowledge about health, well-being, and associated behaviours among young people aged 11-15 years. In 2014, the 7th cycle of HBSC in Canada, the student survey was administered to 29,784 young people in 377 Canadian schools. The 2014 Report differs from the previous 2010 Report in three significant respects. First, unlike the previous report, in which no young people from New Brunswick and Prince Edward Island participated, this survey includes data from all 10 Canadian provinces and all three Canadian territories. Second, this report includes information about a broader range of topics, such as sleep health, spiritual health, use of social media, and chronic conditions. Finally, whereas the previous report focused on mental health, the 2014 Report uses support from contexts (home, school, peers, and community) as its lens to answer the question: Do relationships matter?
