Health Promotion and Chronic Disease Prevention in Canada-Research Policy and Practice最新文献

This qualitative study highlights parents' perspectives on pandemic-related changes to health promotion programming. We conducted 60-minute, semi-structured telephone interviews with 15 parents (all mothers) of children in Grades 4 to 6 between December 2020 and February 2021 in two western Canadian provinces. Transcripts were analyzed through thematic analysis. While some parents found the health promotion materials helpful, most were overwhelmed and did not access the materials, finding them intrusive, being preoccupied with other things and facing their own personal stressors. This study highlights key factors to be addressed and further investigated to ensure the successful delivery of health promotion programming during future crises.

As Canada begins to recover and learn from the COVID-19 pandemic, health equity and public health policies must be a central tenet of reform. Recent work has begun to provide guidance on an equitable pandemic recovery in Canada, which highlights many important groups that require specific consideration in recovery policies.1 There is a key omission in many of these guidelines and, in fact, most health equity efforts-people with disabilities.

Introduction: School-based health-promoting interventions (HPIs) foster adolescent health and well-being. Access to HPIs may differ by the socioeconomic advantage of students at each school (school deprivation). We assessed the importance of health issues and availability of HPIs and extracurricular activities by school deprivation in high schools in Quebec, Canada.

Methods: In 2016/17, 2017/18 and 2018/19, we interviewed school principals or a designee in 48 public high schools classified as disadvantaged (33%) or advantaged (67%). Schools rated whether 13 common health-related issues were important (i.e. warranted intervention) in their student population and reported whether HPIs to address these or other health issues and/or sports or special interest extracurricular activities had been available in the past year.

Results: 84% of disadvantaged schools offered one or more HPIs in the past year compared to 73% of advantaged schools. Higher proportions of disadvantaged schools perceived most of 13 health-related issues as important. HPIs for bullying/exclusion, sex education and physical activity (issues subject to government mandates) were available in most schools. Higher proportions of disadvantaged schools offered non-mandated HPIs (i.e. for healthy eating, mental health/well-being and substance use). Higher proportions of advantaged schools offered extracurricular activities in all areas other than non-competitive sports, which was offered by equal proportions of advantaged and disadvantaged schools.

Conclusion: Government mandates appear to facilitate universal availability of HPIs in schools, possibly boosting equity in school-based health promotion. Further investigation of possible differences in the content, implementation and/or effects of HPIs based on school deprivation is warranted.

Gender identity and sexual attraction are important determinants of health. This study reports distributions of gender identity and sexual attraction among Canadian youth using data from the 2019 Canadian Health Survey on Children and Youth. Among youth aged 12 to 17, 0.2% are nonbinary and 0.2% are transgender. Among youth aged 15 to 17, 21.0%, comprising more females than males, report attraction not exclusive to the opposite gender. Given known associations between health and gender and sexual attraction, oversampling of sexual minority groups is recommended in future studies to obtain reliable estimates for identifying inequities and informing policy.

Introduction: The study objective was to compare the mental health and risk-taking behaviour of Canadian youth in military-connected families to those not in military-connected families in a contemporary sample. We hypothesized that youth in military-connected families have worse mental health, lower life satisfaction and greater engagement in risk-taking behaviours than those not in military-connected families.

Methods: This cross-sectional study used 2017/18 Health Behaviour in School-aged Children in Canada survey data, a representative sample of youth attending Grades 6 to 10. Questionnaires collected information on parental service and six indicators of mental health, life satisfaction and risk-taking behaviour. Multivariable Poisson regression models with robust error variance were implemented, applying survey weights and accounting for clustering by school.

Results: This sample included 16 737 students; 9.5% reported that a parent and/or guardian served in the Canadian military. After adjusting for grade, sex and family affluence, youth with a family connection to the military were 28% more likely to report low well-being (95% CI: 1.17-1.40), 32% more likely to report persistent feelings of hopelessness (1.22-1.43), 22% more likely to report emotional problems (1.13-1.32), 42% more likely to report low life satisfaction (1.27-1.59) and 37% more likely to report frequent engagement in overt risk-taking (1.21-1.55).

Conclusion: Youth in military-connected families reported worse mental health and more risk-taking behaviours than youth not in military-connected families. The results suggest a need for additional mental health and well-being supports for youth in Canadian military-connected families and longitudinal research to understand underlying determinants that contribute to these differences.

Introduction: Research suggests that there is often a high degree of missingness in youth body mass index (BMI) data derived from self-reported measures, which may have a large effect on research findings. The first step in handling missing data is to examine the levels and patterns of missingness. However, previous studies examining youth BMI missingness used logistic regression, which is limited in its ability to discern subgroups or identify a hierarchy of importance for variables, aspects that may go a long way in helping understand missing data patterns.

Methods: This study used sex-stratified classification and regression tree (CART) models to examine missingness in height, body mass and BMI data among 74 501 youth participating in the 2018/19 COMPASS study (a prospective cohort study examining health behaviours among Canadian youth), where 31% of BMI data were missing. Diet, movement, academic, mental health and substance use variables were examined for associations with missingness in height, body mass and BMI.

Results: CART models indicated that the combination of being younger, having a selfperception of being overweight, being less physically active and having poorer mental health yielded female and male subgroups highly likely to be missing BMI values. Survey respondents who did not perceive themselves as overweight and who were older were unlikely to be missing BMI values.

Conclusion: The subgroups identified by the CART models indicate that a sample that deletes cases with missing BMI would be biased towards physically, emotionally and mentally healthier youth. Given the ability of CART models to identify these subgroups and a hierarchy of variable importance, they are an invaluable tool for examining missing data patterns and appropriate handling of missing data.

Introduction: Muscle-strengthening and balance activities are associated with the prevention of illness and injury. Age-specific Canadian 24-Hour Movement Guidelines include recommendations for muscle/bone-strengthening and balance activities. From 2000-2014, the Canadian Community Health Survey (CCHS) included a module that assessed frequency in 22 physical activities. In 2020, a healthy living rapid response module (HLV-RR) on the CCHS asked new questions on the frequency of muscle/bonestrengthening and balance activities. The objectives of the study were to (1) estimate and characterize adherence to meeting the muscle/bone-strengthening and balance recommendations; (2) examine associations between muscle/bone-strengthening and balance activities with physical and mental health; and (3) examine trends (2000-2014) in adherence to recommendations.

Methods: Using data from the 2020 CCHS HLV-RR, we estimated age-specific prevalence of meeting recommendations. Multivariate logistic regressions examined associations with physical and mental health. Using data from the 2000-2014 CCHS, sex-specific temporal trends in recommendation adherence were explored using logistic regression.

Results: Youth aged 12 to 17 years (56.6%, 95% CI: 52.4-60.8) and adults aged 18 to 64 years (54.9%, 95% CI: 53.1-56.8) had significantly greater adherence to the muscle/ bone-strengthening recommendation than adults aged 65 years and older (41.7%, 95% CI: 38.9-44.5). Only 16% of older adults met the balance recommendation. Meeting the recommendations was associated with better physical and mental health. The proportion of Canadians who met the recommendations increased between 2000 and 2014.

Conclusion: Approximately half of Canadians met their age-specific muscle/bonestrengthening recommendations. Reporting on the muscle/bone-strengthening and balance recommendations elevates their importance alongside the already recognized aerobic recommendation.

Introduction: Sex differences exist in children's obesity rates, dietary patterns and television viewing. Television continues to be a source of unhealthy food advertising exposure to children in Canada. Our objective was to examine sex differences in food advertising exposure in children aged 2 to 17 years across four Canadian English language markets.

Methods: We licensed 24-hour television advertising data from the company Numerator for January through December 2019, in four cities (Vancouver, Calgary, Montréal and Toronto) across Canada. Child food advertising exposure overall, by food category, television station, Health Canada's proposed nutrient profiling model, and marketing techniques were examined on the 10 most popular television stations among children and compared by sex. Advertising exposure was estimated using gross rating points, and sex differences were described using relative and absolute differences.

Results: Both male and female children were exposed to an elevated level of unhealthy food advertising and a plethora of marketing techniques across all four cities. Differences between sexes were evident between and within cities. Compared to females, males in Vancouver and Montréal viewed respectively 24.7% and 24.0% more unhealthy food ads/person/year and were exposed to 90.2 and 133.4 more calls to action, 93.3 and 97.8 more health appeals, and 88.4 and 81.0 more products that appeal to children.

Conclusion: Television is a significant source of children's exposure to food advertising, with clear sex differences. Policy makers need to consider sex when developing food advertising restrictions and monitoring efforts.
