RESUMO
Low socioeconomic status (SES) is associated with poor outcomes after out-of-hospital cardiac arrest (OHCA). Patient characteristics, care processes, and other contextual factors may mediate the association between SES and survival after OHCA. Interventions that target these mediating factors may reduce disparities in OHCA outcomes across the socioeconomic spectrum. This systematic review identified and quantified mediators of the SES-survival after OHCA association. Electronic databases (MEDLINE, Embase, PubMed, Web of Science) and grey literature sources were searched from inception to July or August 2023. Observational studies of OHCA patients that conducted mediation analyses to evaluate potential mediators of the association between SES (defined by income, education, occupation, or a composite index) and survival outcomes were included. A total of 10 studies were included in this review. Income (n = 9), education (n = 4), occupation (n = 1), and composite indices (n = 1) were used to define SES. The proportion of OHCA cases that had bystander involvement, presented with an initial shockable rhythm, and survived to hospital discharge or 30 days increased with higher SES. Common mediators of the SES-survival association that were evaluated included initial rhythm (n = 6), emergency medical services response time (n = 5), and bystander cardiopulmonary resuscitation (n = 4). Initial rhythm was the most important mediator of this association, with a median percent excess risk explained of 37.4% (range 28.6%-40.0%; n = 5; 1 study reported no mediation) and mediation proportion of 41.8% (n = 1). To mitigate socioeconomic disparities in outcomes after OHCA, interventions should target potentially modifiable mediators, such as initial rhythm, which may involve improving bystander awareness of OHCA and the need for prompt resuscitation.

The objective of this study was to characterize fruit and vegetable consumption in 9 selected countries of the World Health Organization (WHO) European Region. We analyzed data on fruit and vegetable intake and participant sociodemographic characteristics for 30,455 adults in 9 Eastern European and Central Asian countries via standardized STEPS survey methodology. Fruit and vegetable consumption across all countries was suboptimal, with a high percentage of populations not meeting the WHO-recommended intake of at least 5 servings (400 g) per day. Strengthened implementation of evidence-based policies to increase intake of fruit and vegetables is needed to reduce the burden of and disparities in NCDs.

Objectives: The COVID-19 pandemic has negatively affected children's lifestyle behaviours and mental health and wellbeing, and concerns have been raised that COVID-19 has also increased health inequalities. No study to date has quantified the impact of COVID-19 on health inequalities among children. We compared pre-pandemic vs. post-lockdown inequalities in lifestyle behaviours and mental health and wellbeing among children living in rural and remote northern communities. Methods: We surveyed 473 grade 4-6 students (9-12 years of age) from 11 schools in rural and remote communities in northern Canada in 2018 (pre-pandemic), and 443 grade 4-6 students from the same schools in 2020 (post-lockdown). The surveys included questions on sedentary behaviours, physical activity, dietary intake, and mental health and wellbeing. We measured inequality in these behaviors using the Gini coefficient, a unitless measure ranging from 0 to 1 with a higher value indicating greater inequality. We used temporal changes (2020 vs. 2018) in Gini coefficients to assess the impact of COVID-19 on inequalities in lifestyle behaviours and mental health and wellbeing separately among girls and boys. Results: Inequalities in all examined lifestyle behaviours increased between 2018 and 2020. Inequalities in watching TV, playing video games, and using a cell phone increased among girls, while inequalities in playing video games, using computers and tablets, and consumption of sugar, salt, saturated fat and total fat increased among boys. Changes in inequalities in mental health and wellbeing were small and not statistically significant. Conclusion: The findings suggest that the COVID-19 pandemic has exacerbated inequalities in lifestyle behaviours among children living in rural and remote northern communities. If not addressed, these differences may translate into exacerbated inequalities in future health. The findings further suggest that school health programs can help mitigate the negative impact of the pandemic on lifestyle behaviours and mental health and wellbeing.
RESUMO
A tax on sugar-sweetened beverages (SSB) has been implemented in various jurisdictions. Though research confirmed this tax to reduce sugar consumption and to prevent chronic diseases, it also revealed concerns: one concern relates to the small proportion of sugar in the diet coming from SSBs; and another concern relates to the disproportional tax burden to low-income groups. To inform public health decision makers on alternatives, we examined three 'real world' taxation and subsidy scenarios in Canada: 1) a CAD$0.75/100 g tax on SSBs; 2) a CAD$0.75/100 g tax on free sugar in all foods; and 3) a 20% subsidy on vegetables and fruit (V&F). Using national survey data and a proportional multi-state life table-based Markov model, we simulated the changes in disability-adjusted life years, healthcare costs, tax revenue, intervention costs, and incremental cost-effectiveness ratio for five income quintiles after implementing the three scenarios, over a lifetime of the 2015 Canadian adult population. The first, second and third scenario would prevent 28,921, 262,348 and 551 cases of type 2 diabetes, respectively. They would avert 752,353, 12,167,113, and 29,447 disability-adjusted life years and save CAD$12,942 million, 149,927 million, and 442 million in health care costs, respectively, over a lifetime. Combining the second and third scenarios would lead to the largest health and economic benefits. Although the lowest income quintile would bear a higher sugar tax burden (0.81% of income, CAD$120/person/year), this would be compensated by a coinciding subsidy on V&F (1.30% of income, CAD$194/person/year). These findings support policies that include a tax on all free sugar in foods and a subsidy on V&F as an effective means to reduce chronic diseases and health care costs. Although the sugar tax was financially regressive, the V&F subsidy could compensate for the tax burden of the disadvantaged groups and improve health and economic equity.

OBJECTIVE: To inform strategies aimed at improving blood pressure (BP) control and reducing salt intake, we assessed educational inequalities in high blood pressure (HBP) awareness, treatment and control; physician's advice on salt reduction; and salt knowledge, perceptions and consumption behaviours in Eastern Europe and Central Asia. DESIGN: Data were collected in cross-sectional, population-based nationally representative surveys, using a multi-stage clustered sampling design. Five HBP awareness, treatment and control categories were created from measured BP and hypertension medication use. Education and other variables were self-reported. Weighted multinomial mixed-effects regression models, adjusted for confounders, were used to assess differences across education categories. SETTINGS: Nine Eastern European and Central Asian countries (Armenia, Azerbaijan, Belarus, Georgia, Kyrgyzstan, Republic of Moldova, Tajikistan, Turkey and Uzbekistan). PARTICIPANTS: Nationally representative samples of 30 455 adults aged 25-65 years. RESULTS: HBP awareness, treatment and control varied substantially by education. The coverage of physician's advice on salt was less frequent among participants with lower education, and those with untreated HBP or unaware of their HBP. The education gradient was evident in salt knowledge and perceptions of salt intake but not in salt consumption behaviours. Improved salt knowledge and perceptions were more prevalent among participants who received physician's advice on salt reduction. CONCLUSIONS: There is a strong education gradient in HBP awareness, treatment and control as well as salt knowledge and perceived intake. Enhancements in public and patient knowledge and awareness of HBP and its risk factors targeting socio-economically disadvantaged groups are urgently needed to alleviate the growing HBP burden in low- and middle-income countries.

BACKGROUND: With the increasing concerns about the health and economic burden attributed to sugar-sweetened beverages (SSBs) consumption, SSB taxation has been proposed and implemented in many countries. Many previous economic evaluations of SSB taxation have shown that this kind of policy is cost-effective. However, the magnitude of impact varies. This study aims to design a comprehensive model to estimate the impact and cost-effectiveness of the SSB tax in Canada. METHODS: A proportional multi-state life table-based Markov model was chosen to estimate the impacts of SSB tax in Canada. The health-related quality of life (including disability-adjusted life years (DALYs) and quality-adjusted life years (QALYs)), the costs (including health care costs and intervention costs), and the tax revenue were the main health and economic outcomes. We compared the simulated SSB tax with the current practice from the public health care payer perspective, and the tax was applied to the 2015 adult Canadian population up to 100 years. The economic model was built following guidelines from the Canadian Agency for Drugs and Technologies in Health. RESULTS: After implementing a CAD$0.015/oz SSB tax, 282,104 cases of overweight and obesity, 210,542 cases of diseases, and 2,189 deaths could be prevented. The simulated SSB tax has the potential to avert 2.3 million DALYs, gain 1.5 million QALYs, and save CAD$32,583 million in health care costs in a lifetime period. The incremental cost-effectiveness ratio for the SSB tax was CAD$ -24,933/QALY. The SSB tax with different tax levels (CAD$0.01/oz and CAD$0.02/oz) remained cost-effective. CONCLUSION: Implementing the SSB tax in Canada is a potential cost-effective policy option for reducing obesity and related chronic diseases. The model built in this study provides a more accurate estimate of health and economic impact of SSB tax and could be used to estimate other sugar tax options.

INTRODUCTION: Northern communities in Canada experience a disproportionate burden of chronic diseases including mental illness. To mitigate the growing health inequalities, an ongoing Comprehensive School Health program promoting healthy lifestyle behaviours and mental health and well-being was expanded to rural and remote northern communities. We report on the program's impact on knowledge, attitudes, lifestyle behaviours (healthy eating, physical activity, screen time), weight status and the mental health and well-being of elementary school students during the first four years of implementation. METHODS: Following a repeated cross-sectional design, we surveyed 440, 352 and 384 Grade 4 to 6 students (9-12 years old) from eight schools in 2016, 2018 and 2020/21, respectively. Students were approximately equally represented by girls and boys. RESULTS: Between 2016 and 2018, students reported modest increases in vegetable and fruit consumption and dietary variety; declines in screen time; no changes in physical activity; and declines in attitudes toward healthy lifestyle and in mental health and well-being. Between 2018 and 2020/21, lifestyle behaviours deteriorated substantially, while attitudes and mental health and well-being continued to decline. CONCLUSION: A program that was successful in socioeconomically disadvantaged urban neighbourhoods had a favourable, though modest, impact on selected lifestyle behaviours, but not on attitudes and mental health and well-being, in rural and remote northern communities. In light of cultural differences and logistical challenges in Canada's North, systematic and proactive adaptations to local contexts, increased intensity, and longer program delivery are essential to facilitate sustainable improvements in lifestyle behaviours and mental health and well-being.

Capturing socioeconomic inequalities in relation to chronic disease is challenging since socioeconomic status (SES) encompasses many aspects. We constructed a comprehensive individual-level SES index based on a broad set of social and demographic indicators (gender, education, income adequacy, occupational prestige, employment status) and examined its relationship with smoking, a leading chronic disease risk factor. Analyses were based on baseline data from 17,371 participants of Alberta's Tomorrow Project (ATP), a prospective cohort of adults aged 35−69 years with no prior personal history of cancer. To construct the SES index, we used principal component analysis (PCA) and to illustrate its utility, we examined the association with smoking intensity and smoking history using multiple regression models, adjusted for age and gender. Two components were retained from PCA, which explained 61% of the variation. The SES index was best aligned with educational attainment and occupational prestige, and to a lesser extent, with income adequacy. In the multiple regression analysis, the SES index was negatively associated with smoking intensity (p < 0.001). Study findings highlight the potential of using individual-level SES indices constructed from a broad set of social and demographic indicators in epidemiological research.

OBJECTIVE: Excessive sugar consumption is an established risk factor for various chronic diseases (CDs). No earlier study has quantified its economic burden in terms of health care costs for treatment and management of CDs, and costs associated with lost productivity and premature mortality. This information, however, is essential to public health decision-makers when planning and prioritizing interventions. The present study aimed to estimate the economic burden of excessive free sugar consumption in Canada. METHODS: Free sugars refer to all monosaccharides and disaccharides added to foods plus sugars naturally present in honey, syrups, and fruit juice. Based on free sugar consumption reported in the 2015 Canadian Community Health Survey-Nutrition and established risk estimates for 16 main CDs, we calculated the avoidable direct health care costs and indirect costs. RESULTS: If Canadians were to comply with the free sugar recommendation (consumption below 10% of total energy intake (TEI)), an estimated $2.5 billion (95% CI: 1.5, 3.6) in direct health care and indirect costs could have been avoided in 2019. For the stricter recommendation (consumption below 5% of TEI), this was $5.0 billion (95% CI: 3.1, 6.9). CONCLUSION: Excessive free sugar in our diet has an enormous economic burden that is larger than that of any food group and 3 to 6 times that of sugar-sweetened beverages (SSBs). Public health interventions to reduce sugar consumption should therefore consider going beyond taxation of SSBs to target a broader set of products, in order to more effectively reduce the public health and economic burden of CDs.
RéSUMé: OBJECTIF: La consommation excessive de sucre est un facteur de risque connu pour diverses maladies chroniques. Aucune étude antérieure n'en a chiffré le fardeau économique en termes de coûts de soins de santé pour le traitement et la prise en charge des maladies chroniques, et de coûts associés à la perte de productivité et à la mortalité prématurée. Ces informations sont pourtant essentielles aux décideurs de la santé publique pour planifier les interventions et gérer les priorités. Notre étude a cherché à estimer le fardeau économique de la consommation excessive de sucres libres au Canada. MéTHODE: Les sucres libres désignent tous les monosaccharides et disaccharides ajoutés aux aliments, plus les sucres naturellement présents dans le miel, les sirops et les jus de fruits. D'après la consommation de sucres libres constatée dans l'Enquête sur la santé dans les collectivités canadiennes Nutrition de 2015 et les estimations du risque connues pour 16 grandes maladies chroniques, nous en avons calculé les coûts évitables directs (de soins de santé) et indirects. RéSULTATS: Si les Canadiens s'en tenaient à la consommation recommandée de sucres libres (soit moins de 10 % de l'apport énergétique total [AÉT]), il est estimé que 2,5 milliards de dollars (IC de 95 % : 1,5, 3,6) en coûts directs de soins de santé et en coûts indirects auraient pu être évités en 2019. Si la recommandation plus stricte (consommation inférieure à 5 % de l'AÉT) avait été respectée, les coûts évités se seraient chiffrés à 5 milliards de dollars (IC de 95 % : 3,1, 6,9). CONCLUSION: L'excès de sucres libres dans notre régime représente un fardeau économique énorme, supérieur à celui de tout autre groupe d'aliments et de 3 à 6 fois supérieur à celui des boissons édulcorées au sucre (BÉS). Il faudrait donc envisager des interventions en santé publique visant à réduire la consommation de sucre qui vont au-delà de la taxation des BÉS pour cibler un panier élargi de produits afin de réduire plus efficacement le fardeau sanitaire et économique des maladies chroniques.

Availability of health-promoting interventions (HPIs) may vary across schools serving students with different socioeconomic backgrounds. Our objectives were to describe social inequalities across elementary schools in: (i) level of importance that school principals attribute to 13 common health-related issues among students in their school; (ii) availability of HPIs within their school addressing eight health topics and (iii) (mis)alignment between perceived importance and HPI availability. Data were collected in telephone interviews with school principals in a convenience sample of 171 elementary schools (59% of 291 schools contacted). Schools were categorized as serving very advantaged, moderately advantaged or disadvantaged students. Principals reported how important 13 health issues were among students in their schools and provided data on HPI availability for 8 health issues, 4 of which required school action under government mandates. Higher proportions of principals in schools serving disadvantaged students (36% of all 171 schools) perceived most health issues as important. The mean number of HPIs in the past year was 12.0, 12.1 and 11.7 in schools serving very advantaged, moderately advantaged and disadvantaged students, respectively. Only availability of mental health HPIs differed by school deprivation (60, 43 and 30% in very, moderately and disadvantaged, respectively). Although most schools offered oral health HPIs, dental problems were not perceived as important. Smoking was perceived as not important and smoking-related HPIs were relatively rare (9%). Given rapid evolution in public health priorities, (mis)alignment between perceived importance of specific health issues and HPI availability in elementary schools warrants ongoing reflection.
Interventions that promote health may not be present in all schools. Our objectives were to describe differences across elementary schools in: (i) level of importance that school principals attribute to common health-related issues among students in their own school; (ii) the presence of interventions that address these health issues and (iii) (mis)alignment between perceived importance and presence of interventions. Telephone interviews were conducted with school principals in 171 elementary schools serving very advantaged, moderately advantaged or disadvantaged students. Principals reported how important 13 health-related issues (four of which required school action under government mandates) were among students in their schools and whether interventions were present for 8 of the 13 issues. Higher proportions of principals in schools serving disadvantaged students perceived most health issues as important. Intervention availability did not differ across schools, except that higher proportions of schools serving advantaged students reported mental health interventions. Most schools offered oral health interventions, but dental problems were not perceived as important. Smoking was also not perceived as important and interventions were relatively rare. (Mis)alignment between perceived importance of health issues and intervention availability calls for ongoing reflection.

INTRODUCTION: An association between socioeconomic status (SES) and smoke-free private spaces among smokers could be due to heavier smoking among low SES smokers. We assessed whether quantity smoked or SES are independently associated with smoke-free homes or cars in daily smokers. METHOD: Data were drawn from a cross-sectional telephone survey (2011-2012) of 750 daily smokers age ≥18 years in Quebec, Canada (45% response). Multivariable logistic regression was used to model the independent association between (a) number of cigarettes smoked per day, and (b) each of educational attainment, annual household income, or active employment status and smoke-free homes or cars. RESULTS: Participants were 41.0 years old on average, 57% were female. Median (IQR) number of cigarettes smoked per day was 14 (10, 20). Forty-eight percent of participants reported smoke-free homes; 34% reported smoke-free cars. Quantity smoked was strongly associated with both smoke-free homes and cars. Income and education (but not actively employed) were associated with smoke-free homes. None of the SES indicators were associated with smoke-free cars. CONCLUSIONS: Interventions targeting smokers to promote smoke-free homes and cars should incorporate components to help smokers reduce quantity smoked or preferably, to quit. Interventions targeting smoke-free homes will also need to address SES inequalities by education and income. Our data suggest that reduction in quantity smoked may help smokers reduce SHS exposure in cars, but that an inequality lens may not be relevant.

Current cancer prevention recommendations advise limiting red meat intake to <500 g/week and avoiding consumption of processed meat, but do not differentiate the source of processed meat. We examined the associations of processed meat derived from red v. non-red meats with cancer risk in a prospective cohort of 26 218 adults who reported dietary intake using the Canadian Diet History Questionnaire. Incidence of cancer was obtained through data linkage with Alberta Cancer Registry with median follow-up of 13·3 (interquartile range (IQR) 5·1) years. Multivariable Cox proportional hazards regression models were adjusted for covariates and stratified by age and sex. The median consumption (g/week) of red meat, processed meat from red meat and processed meat from non-red meat was 267·9 (IQR 269·9), 53·6 (IQR 83·3) and 11·9 (IQR 31·8), respectively. High intakes (4th Quartile) of processed meat from red meat were associated with increased risk of gastrointestinal cancer adjusted hazard ratio (AHR): 1·68 (95 % CI 1·09, 2·57) and colorectal cancers AHR: 1·90 (95 % CI 1·12, 3·22), respectively, in women. No statistically significant associations were observed for intakes of red meat or processed meat from non-red meat. Results suggest that the carcinogenic effect associated with processed meat intake may be limited to processed meat derived from red meats. The findings provide preliminary evidence towards refining cancer prevention recommendations for red and processed meat intake.

BACKGROUND: While school-based health prevention programmes are effective in addressing unhealthy diet and physical inactivity, little is known about their economic implications. We conducted an economic evaluation of the programmes that were previously identified as feasible, acceptable, and sustainable in the Canadian context. METHODS: This study builds on a meta-analysis of the effectiveness of feasible, acceptable, and sustainable school-based health promotion programmes. A micro-simulation model incorporated intervention effects on multiple risk factors to estimate incremental cost-effectiveness and return on investment (ROI) of comprehensive school health (CSH), multicomponent, and physical education (PE) curriculum modification programmes. Cost-effectiveness was expressed as the programme costs below which the programme would be cost-effective at a CA$50 000 threshold level. RESULTS: The estimated costs below which interventions were cost-effective per quality-adjusted life year gained were CA$682, CA$444, and CA$416 per student for CSH, multicomponent, and PE curriculum modification programmes, respectively. CSH programmes remained cost-effective per year of chronic disease prevented for costs of up to CA$3384 per student, compared to CA$1911 and CA$1987 for multicomponent and PE curriculum modification interventions, respectively. If the interventions were implemented at total discounted intervention costs of CA$100 per student, ROI through the avoidance of direct healthcare costs related to the treatment and management of chronic diseases would be 824% for CSH, 465% for multicomponent interventions, and 484% for PE curriculum modification interventions. CONCLUSIONS: Whereas each examined intervention types showed favourable economic benefits, CSH programmes appeared to be the most cost-effective and to have the highest ROI.

Purpose: A school nutrition policy (SNP) is one promising school-based health promotion strategy to improve the food environments of First Nations children. The aim of this study was to explore First Nations parents' perceptions of a SNP. Methods: A process evaluation of policy implementation was conducted using a mixed-methods design. Parents (n = 83) completed a 19-question survey to capture their perceptions of the policy. Survey responses informed questions in an 11-question semi-structured interview guide. Transcripts from interviews with parents (n = 10) were analyzed using content analysis to identify barriers and facilitators to policy implementation. Results: Parents were supportive of the SNP and the school's food programs, which they perceived as helping to address community concerns related to nutrition. However, some parents opposed the restriction of unhealthy foods at school celebrations and fundraisers. In addition, despite being aware of the SNP, parents were unable to demonstrate an understanding of the SNP content. Finally, parents struggled to provide their children with healthy foods to bring to school due to lack of affordable and accessible food in the community. Conclusions: Although SNPs may be well-received in First Nations communities, their implementation must be supported by parent involvement and consideration of wider socioeconomic conditions.

AIM: School nutrition policies can improve healthy food access for Indigenous First Nations children in Canada. This study explored First Nations students' perceptions of a school nutrition policy. METHODS: The research was a process evaluation of school nutrition policy implementation using a mixed-methods design. Students in grades 4-12 (n = 94) completed a 17-question survey to capture their perceptions of the policy. Survey data informed an 11-question semi-structured interview guide. Transcripts from interviews with students (n = 20) were analysed using content analysis to identify barriers and facilitators to policy implementation. RESULTS: Key facilitating factors to policy implementation were student support for the policy and taste preferences. Most students (87%) agreed that only healthy foods should be served at school and, in interviews, expressed a preference for healthy food choices. Barriers to policy implementation included foods available at school and lack of communication between students and their teachers and parents. Half (50%) of surveyed students reported that their eating habits at school were average; interviews explained that their diets could be improved by consuming more fruit and vegetables at school. Both surveys and interviews found that communication between students and their parents and teachers about what they ate and drank at school was low. CONCLUSIONS: To support children's healthy eating at school, the school nutrition policy could provide clear guidelines on foods permissible in the school, while considering social and environmental barriers to healthy eating. The involvement of First Nations children in the implementation and evaluation of school nutrition policies is recommended.

AIM: University and college students in wealthy countries may be vulnerable to financial food insecurity. If food insecure students have suboptimal health, their ability to learn and excel in their education could be compromised. This Canadian study examined the relationship of food security status to diet and self-perceived health and academic quality among students receiving emergency food hampers from the Campus Food Bank at University of Alberta. METHODS: A convenience sample of 58 students completed a survey. RESULTS: Of participating students, 10.3% were food secure, 44.8% were moderately food insecure and 44.8% were severely food insecure. Overall, 32.8% rated their general health as fair/poor, 27.6% rated their mental health as fair/poor and 60.3% indicated at least one adverse academic outcome of not having enough money for food. Compared to other participating students, students with severe food insecurity had a greater likelihood of fair/poor general health (odds ratios (OR) 4.03, 95% confidence intervals (CI) 1.10-14.78); fair/poor mental health (OR 4.96, 95% CI 1.28-19.19); being unable to concentrate in class or during an exam (73.1% vs 40.6%, χ2 = 6.12, P = 0.013); relying on food hampers (34.6% vs 9.7%, χ2 = 5.57, P = 0.018); and, consuming fewer daily fruits, vegetables and legumes (2.12 vs 2.97 cup equivalents, P = 0.009). CONCLUSIONS: Food insecurity compromises students' health, diet and academic quality. Campus food banks are not the solution to student hunger. Governmental and university-based programmes and policies are needed to improve the food security situation of university students.
RESUMO
PURPOSE: We compared food insecurity status, coping strategies, demographic characteristics, and self-rated health of international and domestic postsecondary students requesting emergency food hampers from a campus food bank (CFB). METHODS: We collected data from a cross-sectional convenience sample of domestic and international students who accessed the CFB at the University of Alberta. RESULTS: Food insecurity was prevalent (international students: n = 26/27 (96.2%), domestic students: n = 31/31 (100%)). Compared with their domestic peers, international students were less likely to rate their mental health negatively (14.8% vs 38.7%, P = 0.04). The primary income source was government loans (54.8%) for domestic students and research assistantships (33.3%) for international students. To cope with not having enough money for food, the majority of both student groups delayed bill payments or buying university supplies, applied for loans or bursaries, purchased food on credit, or worked more. International students were less likely to ask friends or relatives for food (48.1% vs 77.4%, P = 0.02). CONCLUSIONS: Domestic and international students mostly used similar coping strategies to address food insecurity; however, they paid for their education using different income sources. Distinct strategies for international and domestic students are required to allow more students to cover their educational and living expenses.

OBJECTIVE: To determine whether a school-based health promotion program affects children's weekend physical activity and whether this effect varies according to socioeconomic-status. METHODS: This was a quasi-experimental trial of school-based programs on physical activity levels implemented in disadvantaged neighborhoods in Alberta, Canada. In 2009 and 2011, 7 full days of pedometer data were collected from cross-sectional samples of grade 5 students (age 10-11 years) from 10 intervention schools in low-socioeconomic neighbourhoods and 20 comparison schools in middle-socioeconomic neighbourhoods. Multilevel models assessed differences in step-counts between intervention and comparison groups over-time by weight (objectively measured) and socioeconomic status subgroups. RESULTS: In 2009, children from intervention schools were less active on weekends relative to comparison schools (9212 vs. 11186 steps/day p<0.01). Two years later, daily step-counts on weekend days among children in low socioeconomic intervention schools increased such that they approximated those of children from middle socioeconomic comparison schools (12148 vs. 12121 steps/day p = 0.96). The relative difference in steps between intervention and comparison schools on weekends reduced from -21.4% to 0.2% following the intervention. The normalization of weekend step counts was similar for normal weight (-21.4% to +2.0%) and overweight (-19.1 to +3.9%) children, and was balanced across socioeconomic subgroups. CONCLUSIONS: These data suggest that school-based health promotion is effective for reducing inequities in physical activity levels outside school hours. Investments in school-based health promotion lead to behavior modification beyond the school environment. TRIAL REGISTRATION: ClinicalTrials.gov NCT01914185.

PURPOSE: To describe the food security status, food insecurity coping strategies, characteristics, and experiences of student clients of the Campus Food Bank (CFB) at the University of Alberta in Edmonton, Alberta, Canada. METHODS: A convenience sample of 58 students completed a survey from April 2013 to April 2014. Food security status was determined using the "Adult Food Security Survey Module". RESULTS: Ninety percent of CFB student clients who participated in this study were food insecure, which included both moderately and severely food insecure groups. The most prevalent coping strategies for food insecurity included applying for a loan or bursary (86.2%), seeking employment or working more hours (84.5%), and purchasing food using a credit card (77.6%). Participants were a diverse mix of students, including graduate students (50.0%), international students (46.6%), and caregivers of children (24.1%). The most common primary sources of income were government student loans (29.3%) and research assistantships (20.7%). Most participants (82.8%) liked the food they received from the food bank. CONCLUSIONS: Food insecurity is highly prevalent among student clients of this university-based food bank. Students used a variety of coping strategies to increase their disposable income, highlighting the need for additional strategies to alleviate food insecurity among vulnerable students.
