[Show abstract][Hide abstract] ABSTRACT: The Health Behaviour in School-aged Children study (HBSC) is a continuing, cross-national research project conducted in collaboration with the WHO Regional Office for Europe. There are now 43 participating countries and regions from North America and Europe. The study aims to contribute to new knowledge about the health, well‑being, and health behaviours of young people (aged 11 to 15 years). HBSC is Canada's only national-level health promotion database for this age group. The Federal Government has supported the Canadian HBSC study since 1988.
This report presents key findings from the 2010 cycle of HBSC. Current priorities for the public health system in Canada are particularly emphasized. As the HBSC study has traditionally focused upon the importance of social settings and conditions as potential determinants of health, this focus continues in the current report. In addition, this report examines the mental health of young Canadians as a primary theme.
In addition to our analysis of survey results from over 26,000 students, this report was informed by findings from a national youth engagement workshop. The purpose of this workshop was to obtain insights from a cross-section of young Canadians with respect to the key mental health findings. Efforts made to integrate the perspectives of young people directly into this report were driven by a philosophy that the opinions and insights of youth matter and the Federal Government's role in supporting youth engagement through its committment to the United Nations Convention on the Rights of the Child. This represents a new initiative for HBSC in Canada, with interpretation of the national report findings being enriched by this process.

[Show abstract][Hide abstract] ABSTRACT: The relationships of home and school environments, health risk behaviours and two sentinel adolescent health outcomes were examined in an aetiological analysis. The analysis focused on determinants of the health of young people and the role of school settings in the optimisation of health.
Records were examined from the Canadian sample of the Health Behaviour in School-aged Children (HBSC) Survey. 3402 young people in Ontario, Canada were administered this survey in 2006, of which 1966 were re-administered the survey 1 year later and supplied complete data. Individual items and factor-analytically derived scales were used to examine potential aetiological relationships in a series of structural equation models. Health outcomes examined were serious injury and psychosomatic symptoms. Models developed from cross-sectional data were confirmed longitudinally.
Adolescents who reported negative home and school environments reported higher levels of substance use, psychosomatic symptoms and serious injuries (the latter identified in longitudinal analysis only). Engagement in health risk behaviour partially mediated the link between these two environments and the sentinel health outcomes. Positive school environments were protective in that they moderated associations between negative home environments and engagement in health risk behaviours. The effects observed in longitudinal analyses were generally consistent with those observed cross-sectionally.
Negative home environments clearly place adolescents at risk for engagement in health risk behaviours and associated physical health outcomes. Positive school environments can in part moderate these relationships. Optimisation of school social environments therefore remains warranted as a population health strategy.

[Show abstract][Hide abstract] ABSTRACT: (1) To apply novel population health theory to the modelling of injury experiences in one particular research context. (2) To enhance understanding of the conditions and practices that lead to farm injury.
Prospective, cohort study conducted over 2 years (2007-09).
50 rural municipalities in the Province of Saskatchewan, Canada.
5038 participants from 2169 Saskatchewan farms, contributing 10,092 person-years of follow-up.
Individual exposure: self-reported times involved in farm work. Contextual factors: scaled measures describe socioeconomic, physical, and cultural farm environments. Outcome: time to first self-reported farm injury.
450 farm injuries were reported for 370 individuals on 338 farms over 2 years of follow-up. Times involved in farm work were strongly and consistently related to time to first injury event, with strong monotonic increases in risk observed between none, part-time, and full-time work hour categories. Relationships between farm work hours and time to first injury were not modified by the contextual factors. Respondents reporting high versus low levels of physical farm hazards at baseline experienced increased risks for farm injury on follow-up (HR 1.54; 95% CI 1.16 to 1.47).
Based on study findings, firm conclusions cannot be drawn about the application of population health theory to the study of farm injury aetiology. Injury prevention efforts should continue to focus on: (1) sound occupational health and safety practices associated with long work hours; (2) physical risks and hazards on farms.
