Background: Parents have the potential to substantively influence their child's physical activity. This study identified the parenting practices of US and Canadian parents to encourage or discourage their 5-12 year-old child's physical activity and to examine differences in parenting practices by country, parental sex, age of child, and income.Methods: The sample consisted of 134 US and Canadian parents (54.5% US; 60.4% female) recruited from a web-based panel by a polling firm. The parents answered open-ended questions about what they and other parents do to encourage or discourage their child to be active. Responses were coded using a scheme previously developed to code items used in the published literature. Coded responses were summarized by domain and dimension with differences in responses by country, parental sex, age of child, or household income assessed with a log-linear analysis.Results: The 134 parents provided 649 and 397 responses to ways that parents encourage or discourage their child's physical activity, respectively. Over 70% of responses for practices that encourage physical activity were related to structure of the environment, parental encouragement, and co-participation. The most common response was co-participation in activity with the child. Of the practices that discourage physical activity, 67% were related to structure of the environment, lack of parental control, and modeling poor behaviors. The most common response was allowing screen time. There were no differences in response by country, parental sex, child age, or household income.Conclusions: Parents most often encouraged physical activity through structure and emotional support and discouraged physical activity through lack of structure and control. Understanding how parents influence their child's physical activity may help improve intervention strategies. The current results will inform the development of a physical activity parenting practices instrument. [ABSTRACT FROM AUTHOR]- Published

Background: Few studies have evaluated the effect of adherence to a lifestyle intervention on adolescent health outcomes. The objective of this study was to determine whether adolescent and parental adherence to components of an e-health intervention resulted in change in adolescent body mass index (BMI) and waist circumference (WC) z-scores in a sample of overweight/obese adolescents.Methods: In total, 159 overweight/obese adolescents and their parents participated in an 8-month e-health lifestyle intervention. Each week, adolescents and their parents were asked to login to their respective website and to monitor their dietary, physical activity, and sedentary behaviours. We examined participation (percentage of webpages viewed [adolescents]; number of weeks logged in [parents]) and self-monitoring (number of weeks behaviors were tracked) rates. Linear mixed models and multiple regressions were used to examine change in adolescent BMI and WC z-scores and predictors of adolescent participation and self-monitoring, respectively.Results: Adolescents and parents completed 28% and 23%, respectively, of the online component of the intervention. Higher adolescent participation rate was associated with a decrease in the slope of BMI z-score but not with change in WC z-score. No association was found between self-monitoring rate and change in adolescent BMI or WC z-scores. Parent participation was not found to moderate the relationship between adolescent participation and weight outcomes.Conclusions: Developing strategies for engaging and promoting supportive interactions between adolescents and parents are needed in the e-health context. Findings demonstrate that improving adolescents' adherence to e-health lifestyle intervention can effectively alter the weight trajectory of overweight/obese adolescents.

Despite various national and provincial tobacco, alcohol, and illicit drug surveys in Canada, tracking trends and patterns of use is difficult. These surveys often target specific populations and are prone to sampling or respondent bias. This article describes a feasibility study to provide alcohol-, illicit drug- and tobacco-related morbidity using hospital separation data. Hospital episodes for diseases and conditions wholly or partially attributable to alcohol, illicit drugs, and tobacco by health authority, age group, sex, and specific ICD-10 codes for British Columbia (BC) were obtained. The most responsible diagnosis statistics were combined with aetiologic fractions for each ICD-10 code to estimate the total burden of substance use by health authority. Hospital admissions attributable to alcohol and tobacco each cause approximately 3 and 5 times respectively, that attributable to illicit drugs. The on going analysis of morbidity data will be used to inform the health authorities, and to assist policy makers in creating and evaluating policies. [ABSTRACT FROM AUTHOR]

Adolescents' gender-specific cannabis use rates and their correlates were examined. Data were obtained via a cross-sectional survey conducted in 2004 in British Columbia, Canada, funded by the Canadian Institutes of Health Research. School districts were invited to participate, and schools within consenting districts were recruited. In total, 8,225 students (50% male) from Grades 7 to 12 participated. About 73% were “White,” and 47% had used cannabis in their lifetime. Cannabis users were grouped according to their frequency of use: “never users,” “frequent users,” or “heavy users.” Male heavy cannabis users (14.3% of boys) were more likely to be in Grade 9 or higher; be Aboriginal; report poorer economic status; never feel like an outsider; frequently use alcohol and tobacco; and have lower satisfaction with family, friends, and school compared with boys that never used. Female heavy users (8.7% of girls) were more likely to be in a higher grade; report poorer economic status, mental health, and academic performance; frequently use alcohol and tobacco; and have lower satisfaction with their school compared with female never users. Three important gender differences in the multivariate analysis of the correlates of cannabis use were noted: school grade (for boys only), Aboriginal status (for boys only), and mental health (for girls only). Despite the limitations of relying on self-reports, a subset of youth appears to be at risk for excessive cannabis use that may impair life opportunities and health. The gender differences may be important in the design and implementation of prevention or treatment programs for adolescents. [ABSTRACT FROM AUTHOR]

Previous studies reported differences in clinical treatments provided to ethnic minority children and white children. We examined whether there were differences in clinical treatments provided to Aboriginal and White infants in Canadian Neonatal Intensive Care Units (NICU) and whether these potential differences could be explained by differences in population characteristics, community size, maternal neighbourhood income and hospital treatment policies. The study population included 10 166 infants ( n = 784 Aboriginal and n = 9382 white) admitted to 17 NICUs from all geographical regions of Canada participating in the Canadian Neonatal Network during January 1996–October 1997. We used logistic regression analyses to examine the association between ethnicity and each of seven clinical practices (surfactant treatment, antenatal steroids, blood transfusions, surgery, assisted ventilation, incubator use and transparental nutrition), after adjustment for potential confounders. We repeated theses analyses restricted to infants born <32 weeks gestation. In crude analyses, in the full sample, Aboriginal infants were less likely than white infants to receive surfactants, antenatal steroids, surgery, assisted ventilation, incubator and transparental nutrition. Among infants born <32 weeks gestation, Aboriginal infants were less likely than white infants to receive antenatal steroids, assisted ventilation, incubator and transparental nutrition. In both groups, adjusting for illness severity, gestational age and multiple births separately (model 2) and in combination with neighbourhood income and community size (model 3) resulted in non-significant associations between ethnicity and some of the treatments, but the addition of adjustment for the hospital variation in frequency of use of different treatments resulted in non-significant associations between ethnicity and all seven treatments. Additional studies are needed to explore the significance of hospital frequency of treatment and its relationship to ethnicity. [ABSTRACT FROM AUTHOR]

Background: Parents are an important influence on children's dietary intake and eating behaviors. However, the lack of a conceptual framework and inconsistent assessment of food parenting practices limits our understanding of which food parenting practices are most influential on children. The aim of this study was to develop a food parenting practice conceptual framework using systematic approaches of literature reviews and expert input. Method: A previously completed systematic review of food parenting practice instruments and a qualitative study of parents informed the development of a food parenting practice item bank consisting of 3632 food parenting practice items. The original item bank was further reduced to 110 key food parenting concepts using binning and winnowing techniques. A panel of 32 experts in parenting and nutrition were invited to sort the food parenting practice concepts into categories that reflected their perceptions of a food parenting practice conceptual framework. Multi-dimensional scaling produced a point map of the sorted concepts and hierarchical cluster analysis identified potential solutions. Subjective modifications were used to identify two potential solutions, with additional feedback from the expert panel requested. Results: The experts came from 8 countries and 25 participated in the sorting and 23 provided additional feedback. A parsimonious and a comprehensive concept map were developed based on the clustering of the food parenting practice constructs. The parsimonious concept map contained 7 constructs, while the comprehensive concept map contained 17 constructs and was informed by a previously published content map for food parenting practices. Most of the experts (52%) preferred the comprehensive concept map, while 35% preferred to present both solutions. Conclusion: The comprehensive food parenting practice conceptual map will provide the basis for developing a calibrated Item Response Modeling (IRM) item bank that can be used with computerized adaptive testing. Such an item bank will allow for more consistency in measuring food parenting practices across studies to better assess the impact of food parenting practices on child outcomes and the effect of interventions that target parents as agents of change.

Background: Parents are widely recognized as playing a central role in the development of child behaviors such as physical activity. As there is little agreement as to the dimensions of physical activity-related parenting practices that should be measured or how they should be operationalized, this study engaged experts to develop an integrated conceptual framework for assessing parenting practices that influence multiple aspects of 5 to 12 year old children's participation in physical activity. The ultimate goal of this study is to inform the development of an item bank (repository of calibrated items) aimed at measuring physical activity parenting practices.Methods: Twenty four experts from 6 countries (Australia, Canada, England, Scotland, the Netherlands, & United States (US)) sorted 77 physical activity parenting practice concepts identified from our previously published synthesis of the literature (74 measures) and survey of Canadian and US parents. Concept Mapping software was used to conduct the multi-dimensional scaling (MDS) analysis and a cluster analysis of the MDS solution of the Expert's sorting which was qualitatively reviewed and commented on by the Experts.Results: The conceptual framework includes 12 constructs which are presented using three main domains of parenting practices (neglect/control, autonomy support, and structure). The neglect/control domain includes two constructs: permissive and pressuring parenting practices. The autonomy supportive domain includes four constructs: encouragement, guided choice, involvement in child physical activities, and praises/rewards for their child's physical activity. Finally, the structure domain includes six constructs: co-participation, expectations, facilitation, modeling, monitoring, and restricting physical activity for safety or academic concerns.Conclusion: The concept mapping analysis provided a useful process to engage experts in re-conceptualizing physical activity parenting practices and identified key constructs to include in measures of physical activity parenting. While the constructs identified ought to be included in measures of physical activity parenting practices, it will be important to collect data among parents to further validate the content of these constructs. In conclusion, the method provided a roadmap for developing an item bank that captures key facets of physical activity parenting and ultimately serves to standardize how we operationalize measures of physical activity parenting.

Introduction: British Columbia (BC) declared an overdose public health emergency in 2016. Since then, BC has consistently reported the highest overdose death rates of any province in Canada. In the context of the COVID‐19 pandemic, overdose deaths in BC reached a record high in 2020. This analysis reports on changes in the profile of people who have died of overdose since BC's declaration of COVID‐19 as a public health emergency on 17 March 2020. Methods: Using BC Coroners Service data, Chi‐square tests and multivariable logistic regression were conducted to compare demographic, geographic and post‐mortem toxicology data between people who died of overdose before (17 March–31 December 2019) and after (17 March–31 December 2020) BC's declaration of COVID‐19 as a public health emergency. Results: Overdose deaths observed since 17 March 2020 (n = 1516) more than doubled those observed in the same period in 2019 (n = 744). In the adjusted logistic regression model, odds of death in the post compared to pre‐COVID‐19 period was significantly higher among males compared to females, among all older age groups compared to people aged 30–39, and was lower in public buildings compared to private residences. Discussion and Conclusions: Alongside a significant increase in overdose deaths since BC's declaration of COVID‐19 as a public health emergency, the demographic profile of people who have died of overdose has changed. Ongoing overdose prevention efforts in BC must seek to reach people who remain most isolated, including older adults, who during dual public health emergencies are facing compounded risk of preventable mortality.

Title. Identifying attitudes, beliefs and reported practices of nurses and doctors as immunization providers. Aim. This paper is a report of a study conducted to examine the attitudes, beliefs, behavioural intentions and self-reported behaviour of nurses and physicians relating to key immunization behaviours and compare the findings for nurses and physicians. Background. Immunization is an important and effective public health intervention. Understanding immunization providers’ attitudes and beliefs toward immunization has the potential to improve educational efforts and lead to behavioural change. Method. A postal survey was conducted with all immunization providers in British Columbia, Canada, in 2005. The survey elicited data on demographics, practice characteristics, attitudes, perceived social norms and perceived behavioural control related to key immunization behaviours. Results. Responses were received from 344 nurses and 349 physicians. The response rate was 67% for nurses and 22% for physicians. More nurses than physicians thought that administering all recommended vaccines at one visit was important (89·2% vs. 63·2% P < 0·001); nurses felt more pressure from parents to administer all recommended vaccines (82·4% vs. 48·7% P < 0·001), and nurses were also more likely to intend to give all recommended vaccines at one visit (98·8% vs. 73·8% P < 0·001). Both nurses and physicians thought that their own receipt of influenza vaccine each year was important (88·9%, 87·1% respectively P = 0·65). Conclusion. The foundational work done to develop the survey tool can be used to modify it so that survey findings can be validated according to the Theory of Planned Behaviour. The results could inform the development of behavioural change interventions targeting the identified determinants of immunization provider behaviour. [ABSTRACT FROM AUTHOR]

Background: Illicit drug overdose deaths (IDD) relate to individual drug dose and context of use, including use with other drugs and alcohol. IDD peaked in British Columbia (BC) in 1998 with 417 deaths, and continues to be a public health problem. The objective of this study was to examine IDD in 2006 in BC by place of residence, injury and death, decedents' age and sex and substances identified. Methods: IDD data was obtained through the BC Coroners Office and entered into SPSS (version 14). Fisher's exact and Pearson's ?2 were used for categorical data; Mann-Whitney U-test for continuous variables. Rates were calculated using 2006 population estimates. Results: We identified 223 IDD in BC; 54 (24%) occurred in Vancouver. Vancouver decedents (compared to those occurring outside Vancouver) were older (mean age 43.9 vs. 39.2 years; p < 0.01) and more likely to be male (90.7% vs. 77.5%; p = 0.03). Provincially Aboriginal ethnicity was reported for 19 deaths; 13 (30.2%) of 43 females and 6 (3.3%) of 180 males (p = < 0.001). Cocaine was identified in 80.3%, opiates 59.6%, methadone 13.9%, methamphetamine/ amphetamine 6.3%, and alcohol in 22.9% of deaths. Poly-substance use was common, 2 substances were identified in 43.8% and 3 or more in 34.5% of deaths. Opiates were more frequently identified in Vancouver compared to outside Vancouver (74.1% vs. 55.0%) p = 0.015. Conclusion: Collaboration with the Coroner's office allowed us to analyze IDD in detail including place of death; cocaine, opiates and poly-substance use were commonly identified. Poly-substance use should be explored further to inform public health interventions. [ABSTRACT FROM AUTHOR]

Study objective: To find out if gender and ethnicity are associated with acute myocardial infarction (AMI) symptom recognition and the recommendation of enlisting emergency medical services. Design: In an experiment, a random sample of the public was provided a scenario of a person experiencing symptoms of AMI; the gender of the character (male, female, or indeterminate) was manipulated. Setting: Vancouver, Canada Participants: 976 people from a population based random sample of 3419 people, 40 years of age and older, participated in a telephone survey given in English, Cantonese, Mandarin, and Punjabi. Main results: 78% of the respondents identified the symptoms as heart related. Unadjusted analyses showed that ethnicity, education, income, and AMI knowledge were significantly associated with symptom recognition (Chinese respondents were least likely to identify the symptoms as heart related). Thirty seven per cent recommended calling emergency services, which was associated with symptom recognition, ethnicity (Chinese respondents were least likely to make the recommendation), AMI knowledge, having an immediate family member with AMI, and having talked with a health professional about the signs and symptoms of AMI. Neither the gender of the respondent nor of the affected person in the scenario was associated with symptom recognition. Conclusions: Heart health education must be targeted to and tailored for ethnic communities. Health professionals must discuss the signs and symptoms of AMI, and the correct course of action, with their patients. [ABSTRACT FROM AUTHOR]

Introduction: British Columbia (BC) declared a public health emergency in April 2016 in response to a rapid rise in overdose deaths. Further understanding of health care utilization is needed to inform prevention strategies for individuals who overdose from illegal drugs. Methods: The Provincial Overdose Cohort includes linked administrative data on health care utilization by individuals who experienced an illegal drug overdose event in BC between 1 January 2015 and 30 November 2016. Overdose cases were identified using data from ambulance services, coroners' investigations, poison control centre calls and hospital, emergency department and physician administrative records. In total, 10 455 overdose cases were identified and compared with 52 275 controls matched on age, sex and area of residence for a descriptive analysis of health care utilization. Results: Two-thirds (66%) of overdose cases were male and about half (49%) were 20-39 years old. Over half of the cases (54%) visited the emergency department and about one-quarter (26%) were admitted to hospital in the year before the overdose event, compared with 17% and 9% of controls, respectively. Nevertheless, nearly onefifth (19%) of cases were recorded leaving the emergency department without being seen or against medical advice. High proportions of both cases (75%) and controls (72%) visited community-based physicians. Substance use and mental health-related concerns were the most common diagnoses among people who went on to overdose. Conclusion: People who overdosed frequently accessed the health care system in the year before the overdose event. In light of the high rates of health care use, there may be opportunities to identify at-risk individuals before they overdose and connect them with targeted programs and evidence-based interventions. Further work using the BC Provincial Overdose Cohort will focus on identifying risk factors for overdose events and death by overdose. [ABSTRACT FROM AUTHOR]

Research to understand how parents influence their children's dietary intake and eating behaviors has expanded in the past decades and a growing number of instruments are available to assess food parenting practices. Unfortunately, there is no consensus on how constructs should be defined or operationalized, making comparison of results across studies difficult. The aim of this study was to develop a food parenting practice item bank with items from published scales and supplement with parenting practices that parents report using. Items from published scales were identified from two published systematic reviews along with an additional systematic review conducted for this study. Parents (n = 135) with children 5-12 years old from the US and Canada, stratified to represent the demographic distribution of each country, were recruited to participate in an online semi-qualitative survey on food parenting. Published items and parent responses were coded using the same framework to reduce the number of items into representative concepts using a binning and winnowing process. The literature contributed 1392 items and parents contributed 1985 items, which were reduced to 262 different food parenting concepts (26% exclusive from literature, 12% exclusive from parents, and 62% represented in both). Food parenting practices related to 'Structure of Food Environment' and 'Behavioral and Educational' were emphasized more by parent responses, while practices related to 'Consistency of Feeding Environment' and 'Emotional Regulation' were more represented among published items. The resulting food parenting item bank should next be calibrated with item response modeling for scientists to use in the future. [ABSTRACT FROM AUTHOR]

Background: Adherence to e-health obesity interventions is a significant challenge. Purpose: We examined the individual and household predictors of adolescents' adherence to a Web-based lifestyle intervention. Methods: One hundred sixty overweight/obese adolescents and one of their parents enrolled in the 8-month e-health intervention. Structural equation modeling was used to examine individual factors from the theory of planned behavior and self-determination theory and household factors (food/soda availability, parenting, environment) that predict adolescents' adherence to components of the intervention. Results: We explained 10.8 to 36.9 % of the total variance in adherence to components of the intervention. Intrinsic motivation and parenting practices and styles directly predicted adherence. Relatedness and autonomy support indirectly predicted adherence via intrinsic motivation. Finally, household income modulated these effects. Conclusion: Taking a self-regulatory perspective (i.e., accounting for intrinsic motivation) contributes to our understanding of intervention adherence, but the household environment may play a greater role in facilitating adolescent behavior change.

Objectives. We investigated whether periodic increases in minimum alcohol prices were associated with reduced alcohol-attributable hospital admissions in British Columbia. Methods. The longitudinal panel study (2002-2009) incorporated minimum alcohol prices, density of alcohol outlets, and age- and gender-standardized rates of acute, chronic, and 100% alcohol-attributable admissions. We applied mixed-method regression models to data from 89 geographic areas of British Columbia across 32 time periods, adjusting for spatial and temporal autocorrelation, moving average effects, season, and a range of economic and social variables. Results. A 10% increase in the average minimum price of all alcoholic beverages was associated with an 8.95% decrease in acute alcohol-attributable admissions and a 9.22% reduction in chronic alcohol-attributable admissions 2 years later. A Can$ 0.10 increase in average minimum price would prevent 166acute admissions in the 1st year and 275 chronic admissions 2 years later. We also estimated significant, though smaller, adverse impacts of increased private liquor store density on hospital admission rates for all types of alcohol attributable admissions. Conclusions. Significant health benefits were observed when minimum alcohol prices in British Columbia were increased. By contrast, adverse health outcomes were associated with an expansion of private liquor stores. [ABSTRACT FROM AUTHOR]

Aim To investigate relationships between periodic increases in minimum alcohol prices, changing densities of liquor stores and alcohol-attributable ( AA) deaths in British Columbia, Canada. Design Cross-section (16 geographic areas) versus time-series (32 annual quarters) panel analyses were conducted with AA deaths as dependent variables and price, outlet densities and socio-demographic characteristics as independent variables. Setting and participants Populations of 16 Health Service Delivery Areas in British Columbia, Canada. Measurements Age-sex-standardized rates of acute, chronic and wholly AA mortality; population densities of restaurants, bars, government and private liquor stores; minimum prices of alcohol in dollars per standard drink. Findings A 10% increase in average minimum price for all alcoholic beverages was associated with a 31.72% [95% confidence interval ( CI): ± 25.73%, P < 0.05] reduction in wholly AA deaths. Significantly negative lagged associations were also detected up to 12 months after minimum price increases for wholly but not for acute or chronic AA deaths. Significant reductions in chronic and total AA deaths were detected between 2 and 3 years after minimum price increases. Significant but inconsistent lagged associations were detected for acute AA deaths. A 10% increase in private liquor stores was associated with a 2.45% (95% CI: ± 2.39%, P < 0.05), 2.36% (95% CI: ± 1.57%, P < 0.05) and 1.99% (95% CI: ± 1.76%, P < 0.05) increase in acute, chronic and total AA mortality rates. Conclusion Increases in the minimum price of alcohol in British Columbia, Canada, between 2002 and 2009 were associated with immediate and delayed decreases in alcohol-attributable mortality. By contrast, increases in the density of private liquor stores were associated with increases in alcohol-attributable mortality. [ABSTRACT FROM AUTHOR]

The Canadian Community Epidemiology Network on Drug Use (CCENDU) Vancouver-site committee is comprised of representatives from national/provincial/local health and enforcement agencies. It collects, collates and interprets recent local data relating to major drug use to produce regular reports exploring Vancouver data with provincial and national comparisons. Meetings of committee members allow identification of current concerns, inform the data and broaden the context for the members. The seventh Vancouver site report since 1996 was published in July 2007. Data trends are explored with input from committee members; changes in data collection and definitions are clarified. The committee strives to share the knowledge with health authorities, policy makers, agencies and the public. [ABSTRACT FROM AUTHOR]

This pilot project is a province-wide and nationally-supported collaboration intended to add value to existing monitoring and surveillance exercises that currently exist and are being developed in Canada. The fundamental aim is to create a system that generates a timely flow of data on hazardous patterns of substance use and related harms so as to inform public debate, to support effective policy, and to facilitate policy-relevant epidemiological research. Pilot and feasibility exercises have been conducted in relation to developing consistent questions in surveys of general and special populations, treatment system data, data on the contents of drugs seized by police, interviews with police, rates of alcohol and other drug mortality and morbidity, alcohol sales data, and data from the emergency departments. Wherever possible, links with the equivalent national data collection processes have been established to create consistencies. This article provides a general overview of the BC pilot monitoring system and discusses some potential advantages of planning and designing a comprehensive system with built-in consistencies across data collection elements.
