A Novel Anti-nucleocapsid Antibody Avidity Method for Identifying SARS-CoV-2 Reinfections.

Detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfections is challenging with current serology assays and is further complicated by the marked decrease in routine viral testing practices as viral transmission increased during Omicron. Here, we provide proof-of-principle that high-avidity anti-nucleocapsid (N) antibodies detects reinfections after a single infection with higher specificity (85%; 95% confidence interval [95% CI], 80%-90%) compared to anti-N antibody levels (72%; 95% CI, 66%-79%) in a vaccinated cohort. This method could be used to retroactively investigate the epidemiology and incremental long-term health consequences of SARS-CoV-2 reinfections.

Factors associated with physical activity policy and practice implementation in British Columbia's childcare settings: a longitudinal study.

BACKGROUND: In 2016-17, the government of British Columbia (BC) enacted a mandatory policy outlining Active Play Standards (AP Standards) alongside a capacity building initiative (Appetite to Play) focused on implementing policies and practices to support physical activity in childcare centres. We aimed to identify factors at the provider and organizational levels as well as attributes of the Standards hypothesized to influence implementation (i.e., changes in policies and practices). METHODS: We conducted surveys before (2016-2017) and after (2018-2019) enforcement of the AP Standards among 146 group childcare centres across BC. The 2018-19 surveys measured theoretically based constructs associated with implementation of policies and practices (9 childcare- and 8 provider- level characteristics as well as 4 attributes of the licensing standards). Characteristics that were associated in simple regression models were entered in multivariable regression models to identify factors associated with policy and practice changes related to fundamental movement skills (FMS), screen time, total amount of active play (AP) and total amount of outdoor AP from baseline to follow-up. RESULTS: In multivariable analyses, higher staff capacity (OR = 2.1, 95% 1.2, 3.7) and perceived flexibility of the standards (OR: 3.3, 95% 1.5, 7.1) were associated with higher odds of a policy change related to FMS. Higher staff commitment to the AP standards was associated with a higher odds of policy changes related to screen time (OR = 1.6, 95% CI: 1.1, 2.4) and amount of AP (OR: 1.5, 95% 1.0, 2.3). Higher institutionalization of PA policies was associated with a higher odds of policy changes related to the amount of AP (OR: 5.4, 95% CI: 1.5, 20). Higher self-efficacy was associated with a higher odds of policy changes related to outdoor AP (OR = 2.9, 95% 1.1, 7.8). Appetite to Play training was a positively associated with practice changes related to FMS (ß = 0.5, 95% CI: 0.1, 0.9). CONCLUSIONS: A hierarchy of theoretically defined factors influenced childcare providers' implementation of the AP Standards in BC. Future research should test the feasibility of modifying these factors to improve the implementation of PA policy and practice interventions in this setting.

Implementing active play standards: a qualitative study with licensed childcare providers in British Columbia, Canada.

With an increasing number of children attending regular early childhood education and care (ECEC), this setting presents an opportunity to develop physical activity habits and movement skills of children. These behaviours play an important role in the development and well-being of children. In 2017, an Active Play Standard was introduced in British Columbia, Canada, to mandate practices related to physical activity, screen time and movement skill development in licensed ECEC. A capacity-building initiative including training and online resources was released alongside these guidelines to support implementation. The purpose of this study was to qualitatively examine the barriers and facilitators ECEC practitioners faced in implementing the standard, and to explore the role of the capacity-building initiative. Data were collected via semi-structured telephone interviews with educators (n = 23). Data were coded using thematic analysis and sorted into three major themes influencing provision of physical activity opportunities: attributes and impact of the Active Play standard and capacity-building workshop, characteristics of providers and characteristics of ECEC settings. Future studies should consider targeting factors including organizational culture and climate, and provider capacity to provide physical activity and fundamental movement skill programming, and support for facility level policies and collaborative planning processes that create a positive physical activity culture.

Does an active play standard change childcare physical activity and healthy eating policies? A natural policy experiment.

BACKGROUND: In 2017, the provincial government of British Columbia (BC) implemented a mandatory policy outlining Active Play Standards (AP Standards) to increase physical activity (PA) levels, sedentary and motor skills among children attending licensed childcare centers. Concurrently, a capacity-building initiative was launched to help implement policies and practices supporting both PA and healthy eating (HE) in the early years. This study evaluated differences in center-level PA and HE policies and practices before and after the enforcement of the new provincial AP Standards. METHODS: Using a repeat cross-sectional design, surveys were distributed to managers and staff of licensed childcare facilities serving children aged 2-5 years before (2016-2017 or 'time 1') and after (2018-2019 or 'time 2') implementation of the AP Standards across BC. The total sample included 1,459 respondents (910 and 549 respondents at time 1 and time 2, respectively). Hierarchical mixed effects models were used to examine differences in 9 and 7 PA/sedentary policies and practices, respectively, as well as 11 HE policies between time 1 and time 2. Models controlled for childcare size and area-level population size, education, and income. RESULTS: Compared to centers surveyed at time 1, centers at time 2 were more likely to report written policies related to: fundamental movement skills, total amount of Active Play (AP) time, staff-led AP, unfacilitated play/free play, total amount of outdoor AP time, limiting screen time, breaking up prolonged sitting, staff role modeling of PA, and training staff about PA (P < 0.01 for all 9 policies examined). Compared to time 1, centers at time 2 reported more frequent practices related to ensuring children engaged in at least 120 min of AP, 60 min of outdoor AP daily, and limiting screen time (P < 0.01 for 3 out of 7 practices examined). Despite no additional policy intervention related to HE, centers were more likely to report having written policies related to: HE education for children, encouraging new foods, having family-style meals, offering only milk or water, limiting the amount of juice served, staff role modeling of HE, limiting the types of foods at parties/celebrations and foods brought from home (P < 0.05 for 9 out of 11 HE policies). CONCLUSION: Approximately a year after the implementation of a governmental policy targeting PA supported by a capacity-building initiative, childcare centers reported positive changes in all 9 PA/sedentary policies examined, all 3 out of 7 PA/sedentary practices and 9 out of 11 HE policies evaluated at the center-level.

The Aim2Be mHealth Intervention for Children With Overweight or Obesity and Their Parents: Person-Centered Analyses to Uncover Digital Phenotypes.

BACKGROUND: Despite the growing number of mobile health (mHealth) interventions targeting childhood obesity, few studies have characterized user typologies derived from individuals' patterns of interactions with specific app features (digital phenotypes). OBJECTIVE: This study aims to identify digital phenotypes among 214 parent-child dyads who used the Aim2Be mHealth app as part of a randomized controlled trial conducted between 2019 and 2020, and explores whether participants' characteristics and health outcomes differed across phenotypes. METHODS: Latent class analysis was used to identify distinct parent and child phenotypes based on their use of the app's behavioral, gamified, and social features over 3 months. Multinomial logistic regression models were used to assess whether the phenotypes differed by demographic characteristics. Covariate-adjusted mixed-effect models evaluated changes in BMI z scores (zBMI), diet, physical activity, and screen time across phenotypes. RESULTS: Among parents, 5 digital phenotypes were identified: socially engaged (35/214, 16.3%), independently engaged (18/214, 8.4%) (socially and independently engaged parents are those who used mainly the social or the behavioral features of the app, respectively), fully engaged (26/214, 12.1%), partially engaged (32/214, 15%), and unengaged (103/214, 48.1%) users. Married parents were more likely to be fullyengaged than independently engaged (P=.02) or unengaged (P=.01) users. Socially engaged parents were older than fullyengaged (P=.02) and unengaged (P=.01) parents. The latent class analysis revealed 4 phenotypes among children: fully engaged (32/214, 15%), partially engaged (61/214, 28.5%), dabblers (42/214, 19.6%), and unengaged (79/214, 36.9%) users. Fully engaged children were younger than dabblers (P=.04) and unengaged (P=.003) children. Dabblers lived in higher-income households than fully and partiallyengaged children (P=.03 and P=.047, respectively). Fully engaged children were more likely to have fully engaged (P<.001) and partiallyengaged (P<.001) parents than unengaged children. Compared with unengaged children, fully and partiallyengaged children had decreased total sugar (P=.006 and P=.004, respectively) and energy intake (P=.03 and P=.04, respectively) after 3 months of app use. Partially engaged children also had decreased sugary beverage intake compared with unengaged children (P=.03). Similarly, children with fully engaged parents had decreased zBMI, whereas children with unengaged parents had increased zBMI over time (P=.005). Finally, children with independently engaged parents had decreased caloric intake, whereas children with unengaged parents had increased caloric intake over time (P=.02). CONCLUSIONS: Full parent-child engagement is critical for the success of mHealth interventions. Further research is needed to understand program design elements that can affect participants' engagement in supporting behavior change.

Parental Autonomy Support in the Context of Parent-Child Negotiation for Children's Independent Mobility: 'I Always Feel Safer With My Parents' to 'Boom! Bust Down Those Walls!'

Autonomy - acting volitionally with a sense of choice - is a crucial right for children. Given parents' pivotal position in their child's autonomy development, we examined how parental autonomy support and children's need for autonomy were negotiated and manifested in the context of children's independent mobility - children's ability to play, walk or cycle unsupervised. We interviewed 105 Canadian children between 10 and 13-years-old and their parents (n = 135) to examine child-parents' negotiation patterns as to children's independent mobility. Four patterns emerged, varying on parental autonomy support and children's need/motivation for independent mobility: (1) child/parent dyad wants to increase independent mobility; (2) child only wants to increase independent mobility while parents do not; (3) child does not want to increase independent mobility while parents do; and (4) child/parent dyad does not want to increase independent mobility. Findings illuminate the importance of recognizing children as active and capable agents of change.

Identifying and predicting food parenting practice profiles among Canadian parents.

BACKGROUND: Food parenting practices (FPP) can affect children's eating behaviours, yet little is known about how various FPP co-occur. The primary aim was to identify profiles of FPPs use among Canadian parents. Secondary aims included examining sociodemographic correlates of FPP profiles and evaluating whether children's eating behaviours differed across FPP profiles. METHODS: Parents (n = 799) of 5-12-year-old children completed a validated FPP Item Bank and the Children's Eating Behaviour Questionnaire. Latent Class Analysis (LCA) was used to identify distinct FPP profiles. Regression analyses were used to explore associations between FPP profiles, sociodemographic variables (race, sex and education) and children's eating behaviours (emotional overeating, food responsiveness, food fussiness and satiety responsiveness). RESULTS: LCA revealed 6 FPP profiles: healthy eating environment, high engagement, reactive, high structure, controlling and low engagement. Relative to their non-White counterparts, White parents were more likely to belong in the healthy eating environment, high structure and low engagement profiles. Relative to fathers, mothers were more likely to fall in the healthy eating environment compared to low engagement profile. Parents with some post-secondary education were more likely to belong in the healthy eating environment, high structure and reactive profiles compared to the controlling profile. Emotional overeating and food responsiveness scores were lowest for healthy eating environment, high structure, low engagement profiles. Parents in the healthy eating environment profile also reported lower food fussiness scores compared to parents in the high engagement, high structure, reactive and controlling profiles. CONCLUSIONS: Findings suggest that a continuum of 6 FPP profiles may be present among Canadian parents, representing parents who use either all (high engagement), some (healthy eating environment, reactive, high structure, controlling) or little (low engagement) of the FPP examined. Future longitudinal research should evaluate how various FPP profiles influence the development of children's eating behaviors, dietary intakes and weight status.

Are fathers' and mothers' food parenting practices differentially associated with children's eating behaviors?

Little is known about how fathers' food parenting practices (FPP) are linked with children's eating behaviors and whether these associations differ from mothers. This study examined associations between paternal and maternal FPP and eating behaviors among children aged 5-12 years. A sample of 565 parents (53% fathers) completed: 1) the FPP item bank, which measured 11 FPP constructs from three domains of parenting (control, autonomy promotion, and structure) and 2) the Children's Eating Behavior Questionnaire (CEBQ), to assess four constructs (emotional overeating, food responsiveness, satiety responsiveness and food fussiness). Multivariable linear regressions evaluated associations between FPP and CEBQ constructs, and models were run separately for fathers and mothers. Similarities emerged between fathers and mothers: 1) use of restriction for weight practices were positively associated with emotional overeating and food responsiveness; 2) use of practices to accommodate the child around food and use of practices to involve the child were positively and negatively associated, respectively, with food fussiness; and 3) use of practices to accommodate the child, or coercive controlling practices, was positively associated with emotional overeating. Differences emerged between fathers and mothers in terms of FPP associated with children's food and satiety responsiveness, with a greater number of fathers' FPP predictive of these behaviors. Although similarities exist between mothers and fathers, these findings suggest that fathers likely exert a unique influence on their children's eating behaviors and stress the need for interventions to account for the role each parent plays promoting healthy eating habits.

Gender plays a role in adolescents' dietary behaviors as they transition to secondary school.

Little research explores how changes in adolescents' peer, family and school environments may influence dietary behaviors during the shift from elementary school to secondary school and whether boys and girls experience these changes in similar ways. Drawing on Bronfenbrenner's socio-ecological model and Ridgeway's gendered framework, thematic analysis of twenty-seven semi-structured interviews with parent-adolescent dyads reveals that changes in adolescents' peer, family and school environments affect dietary behaviors following the transition in gendered ways. Within the peer context, food facilitates friendships among girls. Girls use food to forge intimate relationships with their peers whereas boys do not report relying on their peers to influence their dietary choices. In the family environment, gender-based body ideals (i.e., being strong and fit for boys versus being thin for girls) become more apparent and influential over adolescents' dietary behaviors. In some families, parents oppose gender-based body ideals (i.e., food restriction among girls) whereas in others, parents' expectations around food become supportive of gendered norms (i.e., encouraging food consumption among boys to gain muscle or acquiring food literacy skills among girls). Within the school context, socializing emerges as a key priority above eating at lunchtime, but boys and girls engage in this socialization differently. Girls use their lunch hour to socialize with peers through sedentary activities whereas boys socialize through team sports. In summary, gender plays a role in how changes in the peer, family and school environments influence boys' and girls' dietary behaviors as they transition into secondary school. Future public health interventions should consider using a targeted gender approach to encourage adolescents to make healthier food choices.

Appetite for change? Facilitators and barriers to nutrition guideline implementation in Canadian recreational facilities.

As providers of community-based physical activity programs, recreation and sports facilities serve as an important resource for health promotion. Unfortunately, the food environments within these settings often do not reflect healthy eating guidelines. This study sought to describe facilitators and barriers to implementing provincial nutrition guidelines in recreation and sports facilities in three Canadian provinces with nutrition guidelines. Semi-structured interviews were analysed thematically to identify facilitators and barriers to implementing provincial nutrition guidelines. Facilitators and barriers were then categorised using a modified "inside out" socio-ecological model that places health-related and other social environments at the centre. A total of 32 semi-structured interviews were conducted at two time-points across the three guideline provinces. Interview participants included recreation staff managers, facility committee or board members and recreation volunteers. Eight facilitators and barriers were identified across five levels of the inside out socio-ecological model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Findings reinforce the importance of top down (clear expectations regarding guideline implementation at the time of approval) and bottom up (need for buy-in from multiple stakeholders) approaches to ensure successful implementation of nutrition guidelines. The application of a modified socio-ecological model allowed for a more nuanced understanding of leverage points to support successful guideline implementation. Lay summary Healthy eating is an important behaviour for preventing chronic diseases. Supporting people to access healthy foods in places where they live, learn, work or play is a public health priority. Recreation and sports facilities are a setting where people can be physically active. Unfortunately, the food environment in these settings may not reflect nutrition guidelines. In this study, we interviewed key stakeholders from recreation and sports facilities in three Canadian provinces who had put guidelines for healthy eating in place. We used a specific framework to do this called the inside out socio-ecological model. Eight facilitators and barriers were identified using this model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Our findings can help people working in recreation and sports facilities to identify issues that may help or hinder healthy food provision in these settings.

The English Knee Self-Efficacy Scale is a valid and reliable measure for knee-specific self-efficacy in individuals with a sport-related knee injury in the past 5 years.

PURPOSE: To translate and cross-culturally adapt the Swedish Knee Self-Efficacy Scale (K-SES) into English and evaluate the measurement properties in a sample of individuals with previous knee injury. METHODS: Translation, cross-cultural adaptation, and evaluation followed the Beaton multi-step process and COSMIN guidelines. Participants (n = 125) aged 16-60 years with a sport-related intra-articular tibiofemoral or patellofemoral injury within the last 5 years completed the K-SES, Knee Injury and Osteoarthritis Outcome Score, Anterior Cruciate Ligament-Return to Sport After Injury Scale, Tegner Activity Level Scale, and Multi-dimensional Health Locus of Control. Confirmatory factor analysis (CFA) tested a-priori two-factor structure and model fit. Cronbach-alpha, intra-class correlation coefficient (ICC), and absolute reliability (Bland-Altman plots) were calculated. Construct validity was assessed by eight pre-defined hypotheses. A sub-group of participants (n = 42) completed the K-SES twice to assess intra-rater reliability. RESULTS: The cross-cultural adaptation generated an English K-SES with face and content validity. The original two-factor structure was rejected based on CFA and a revised solution informed by Exploratory Factor analysis resulted in an adequate fit. All construct validity hypotheses were confirmed. The K-SES showed good internal consistency [Factor (F1: α = 0.96; F2: α = 0.73)], intra-rater reliability (ICC = 0.92), and no systematic bias between repeated measurements. CONCLUSION: The English K-SES is a valid and reliable measure for knee-specific self-efficacy in individuals who have sustained a sport-related intra-articular knee injury in the previous 5 years. LEVEL OF EVIDENCE: IV.

Calibration of the food parenting practice (FPP) item bank: tools for improving the measurement of food parenting practices of parents of 5-12-year-old children.

PURPOSE: There has been a call to improve measurement rigour and standardization of food parenting practices measures, as well as aligning the measurement of food parenting practices with the parenting literature. Drawing from an expert-informed conceptual framework assessing three key domains of food parenting practices (autonomy promotion, control, and structure), this study combined factor analytic methods with Item Response Modeling (IRM) methodology to psychometrically validate responses to the Food Parenting Practice item bank. METHODS: A sample of 799 Canadian parents of 5-12-year-old children completed the Food Parenting Practice item bank (129 items measuring 17 constructs). The factorial structure of the responses to the item bank was assessed with confirmatory factor analysis (CFA), confirmatory bi-factor item analysis, and IRM. Following these analyses, differential Item Functioning (DIF) and Differential Response Functioning (DRF) analyses were then used to test invariance properties by parents' sex, income and ethnicity. Finally, the efficiency of the item bank was examined using computerized adaptive testing simulations to identify the items to include in a short form. RESULTS: Overall, the expert-informed conceptual framework was predominantly supported by the CFA as it retained the same 17 constructs included in the conceptual framework with the exception of the access/availability and permissive constructs which were respectively renamed covert control and accommodating the child to better reflect the content of the final solution. The bi-factor item analyses and IRM analyses revealed that the solution could be simplified to 11 unidimensional constructs and the full item bank included 86-items (empirical reliability from 0.78 to 0.96, except for 1 construct) and the short form had 48 items. CONCLUSION: Overall the food parenting practice item bank has excellent psychometric properties. The item bank includes an expanded version and short version to meet various study needs. This study provides more efficient tools for assessing how food parenting practices influence child dietary behaviours. Next steps are to use the IRM calibrated item bank and draw on computerized adaptive testing methodology to administer the item bank and provide flexibility in item selection.

The physical activity parenting practices (PAPP) item Bank: a psychometrically validated tool for improving the measurement of physical activity parenting practices of parents of 5-12-year-old children.

BACKGROUND: Many tools have been developed to measure physical activity parenting practices (PAPP). Currently, there is little standardization on how PAPP constructs are operationalized for 5-12 year-old children. Given this lack of consistency our team have started the process of standardizing the measurement of PAPP by developing an item bank which was conceptually informed by 24 experts from 6 countries. PURPOSE: The purpose of this paper is to present the psychometric properties of the PAPP item bank using the expert-informed PAPP conceptual framework. METHODS: A sample (N = 626) of Canadian parents completed the PAPP item bank (100 items measuring 12 constructs). Confirmatory Factor Analyses (CFA), confirmatory bi-factor item analyses, and Item Response Modeling (IRM) were used to assess the structural validity of scores derived from the PAPP item bank. Differential Item Functioning (DIF) and Differential Response Functioning (DRF) were used to determine whether the PAPP items are invariant by parent sex, ethnicity of parent, and household income. Finally, Computerized Adaptive Testing (CAT) simulations were used to determine the efficiency of the item bank - this involved ascertaining whether each construct can be assessed with fewer items. RESULTS: The PAPP expert-informed conceptual framework was mainly supported by the CFA analyses. Notable changes included: a) collapsing smaller constructs into one general construct (modeling, co-participation, and monitoring constructs were collapsed into a construct assessing nondirective support); or b) splitting a construct into two smaller constructs (restrict for safety reason construct was split into indoor physical activity restriction and allowance for unsupervised outside physical activity). While the CFA analyses supported the structural validity of 11 constructs, the bi-factor item analyses and IRM analyses supported collapsing correlated constructs into more general constructs. These analyses further reduced the number of constructs measured by the PAPP item bank to nine constructs (65 items - reliability ranging from .79 to .94). As seven of the PAPP constructs had reliability greater than .80, CAT simulations further reduced the number of items to 31 items. CONCLUSION: Overall, the PAPP item bank has excellent psychometric properties and provides an efficient way to assess PAPP.

Development of a consensus statement on the role of the family in the physical activity, sedentary, and sleep behaviours of children and youth.

BACKGROUND: Children and youth who meet the physical activity, sedentary, and sleep behaviour recommendations in the Canadian 24-Hour Movement Guidelines are more likely to have desirable physical and psychosocial health outcomes. Yet, few children and youth actually meet the recommendations. The family is a key source of influence that can affect lifestyle behaviours. The purpose of this paper is to describe the process used to develop the Consensus Statement on the Role of the Family in the Physical Activity, Sedentary, and Sleep Behaviours of Children and Youth (0-17 years) and present, explain, substantiate, and discuss the final Consensus Statement. METHODS: The development of the Consensus Statement included the establishment of a multidisciplinary Expert Panel, completion of six reviews (three literature, two scoping, one systematic review of reviews), custom data analyses of Statistics Canada's Canadian Health Measures Survey, integration of related research identified by Expert Panel members, a stakeholder consultation, establishment of consensus, and the development of a media, public relations, communications and launch plan. RESULTS: Evidence from the literature reviews provided substantial support for the importance of family on children's movement behaviours and highlighted the importance of inclusion of the entire family system as a source of influence and promotion of healthy child and youth movement behaviours. The Expert Panel incorporated the collective evidence from all reviews, the custom analyses, other related research identified, and stakeholder survey feedback, to develop a conceptual model and arrive at the Consensus Statement: Families can support children and youth in achieving healthy physical activity, sedentary and sleep behaviours by encouraging, facilitating, modelling, setting expectations and engaging in healthy movement behaviours with them. Other sources of influence are important (e.g., child care, school, health care, community, governments) and can support families in this pursuit. CONCLUSION: Family is important for the support and promotion of healthy movement behaviours of children and youth. This Consensus Statement serves as a comprehensive, credible, and current synopsis of related evidence, recommendations, and resources for multiple stakeholders.

Eat, play, live: a randomized controlled trial within a natural experiment examining the role of nutrition policy and capacity building in improving food environments in recreation and sport facilities.

BACKGROUND: Recreation and sport facilities often have unhealthy food environments that may promote unhealthy dietary patterns among children. In response, some Canadian provinces have released voluntary nutrition guidelines for recreation and sport facilities, however implementation has been limited. Organizational capacity building may overcome barriers to implementing guidelines. Eat, Play, Live was a randomized controlled trial embedded within a natural experiment that tested the impact of an 18 month capacity building intervention (CBI) in enhancing implementation of provincial nutrition guidelines, and whether nutrition guidelines were associated with positive changes. Primary outcomes were facility capacity, policy development and food environment quality. METHODS: Recreation and sport facilities in three guideline provinces were randomized into a guideline + CBI (GL + CBI; n = 17) or a guideline only comparison condition (GL-ONLY; n = 15). Facilities in a province without guidelines constituted a second comparison condition (NO-GL; n = 17). Facility capacity, policy development, and food environment quality (vending and concession) were measured and compared at baseline and follow-up across conditions using repeated measures ANOVA and Chi-square statistics. Healthfulness of vending and concession items was rated as Do Not Sell (least nutritious), Sell Sometimes or Sell Most (most nutritious). RESULTS: There were significant time by condition effects, with significant increases in facility capacity (mean ± SD: 30.8 ± 15.6% to 62.3 ± 22.0%; p <  0.01), nutrition policy development (17.6% developed new policies; p = 0.049), overall quality of the concession food environment (14.7 ± 8.4 to 17.5 ± 7.2; p <  0.001), and in the proportion of Sell Most (3.7 ± 4.4% to 11.0 ± 9.0%; p = 0.002) and Sell Sometimes vending snacks (22.4 ± 14.4% to 43.8 ± 15.8%; p <  0.001) in GL + CBI facilities, with a significant decline in Do Not Sell vending snacks (74.0 ± 16.6% to 45.2 ± 20.1%; p <  0.001). CONCLUSIONS: Significant improvements in facility capacity, policy development and food environment quality occurred in recreation and sport facilities that were exposed to nutrition guidelines and participated in a CBI. Outcomes did not improve in facilities that were only passively or not at all exposed to guidelines. Ongoing capacity building may enhance implementation of voluntary nutrition guidelines, however food environments remained overwhelmingly unhealthy, suggesting additional scope to enhance implementation.

A psychometric study of the Family Resilience Assessment Scale among families of children with autism spectrum disorder.

BACKGROUND: The family system represents a critical context within which children develop. Although raising a child with a disability may represent a challenge to this dynamic system, research demonstrates that families have the capacity to demonstrate both maladaptation and resilience in the face of related stressors. In the current study, we examined the psychometric properties of the Family Resilience Assessment Scale (FRAS) among families of children with autism spectrum disorder (ASD). This tool is the only measure of family resilience that seeks to identify within-family protective factors, including the extent to which they rely on adaptive belief systems, organizational patterns, and communication processes. Identifying protective processes utilized by those who show resilience is critical within both clinical practice and research, as it aligns with a strength-based perspective that builds on what families are doing well. METHODS: Participants included 174 caregivers of individuals with ASD (84% mothers). Caregivers completed the FRAS, as well as the Beach Center Family Quality of Life Scale. The 54-item FRAS was submitted to an exploratory factor analysis, using the iterated principal factor method with a promax rotation. RESULTS: Fifty-one items across 3 factors (Family Communication and Problem Solving, Utilizing Social and Economic Resources, Family Spirituality) were retained, explaining 52% of the total variance. The final scale demonstrated convergent validity with the Family Quality of Life assessment tool. CONCLUSIONS: It is our hope that identifying the optimal scale structure will encourage other researchers to utilize this measure with families of children with ASD, thus continuing to advance the study of family resilience within this unique context.

Comparison of risk engagement and protection survey (REPS) among mothers and fathers of children aged 6-12 years.

BACKGROUND: Parental attitudes regarding child safety and risk engagement play important roles in child injury prevention and health promotion efforts. Few studies have compared mothers' and fathers' attitudes on these topics. This study used the risk engagement and protection survey (REPS) previously validated with fathers to compare with data collected from mothers. METHODS: Multi-group confirmatory factor analysis was used with a sample of 234 mothers and 282 fathers. Eligible parents had a child 6-12 years attending a paediatric hospital for an injury-related or other reason. We tested the factor structure of the survey by examining configural, metric and scalar invariance. Following this, mothers' and fathers' mean scores on the two identified factors of child injury protection and risk engagement were compared. RESULTS: Comparing mothers' and fathers' data showed the two-factor structure of the REPS held for the mothers' data. Comparing mean scores for the two factors suggested that fathers and mothers held equivalent attitudes. For the combined sample, parent injury protection attitude scores were significantly higher for daughters versus sons. In addition, attitude scores were significantly lower for injury protection and higher for risk engagement among parents born in Canada compared with those who were not. CONCLUSIONS: The REPS allows for valid assessment of injury protection and risk engagement factors for fathers and mothers. Mothers conceptualised the two factors as distinct concepts, similar to fathers. The REPS can be used to inform parenting programme development, implementation and evaluation.

Moderating effects of family environment on overweight/obese adolescents' dietary behaviours.

BACKGROUND: The familial environment can influence adolescents' risk for obesity. However, we do not fully understand the mechanisms through which parents can influence overweight/obese adolescents' dietary behaviours, specifically whether parenting practices (e.g., rules or routines) and/or their own dietary behaviours are associated with their overweight/obese adolescent's dietary quality. OBJECTIVES: This study examined whether parenting practices and/or parental modeling of dietary quality are associated with overweight/obese adolescents' dietary quality while considering the moderating effects of parenting styles and family functioning. METHODS: Baseline data from 172 overweight/obese adolescents and one of their parents who enrolled in a lifestyle modification intervention were analyzed [mean age = 13.1 (1.8); mean BMI z-score = 2.70 (0.83)]. Parent-adolescent dyads completed three 24-hr dietary recalls online. An index of dietary quality was computed by summing the scores for different food categories assessed in the dietary recall over 3 days. Parents completed questionnaires about their family functioning, dietary parenting practices (i.e., whether child eats breakfast everyday), and styles (authoritative and permissive). Path analysis was used to model interrelationships among the variables using the Stata software version 13. RESULTS: Parental modeling of dietary quality was significantly associated with adolescent dietary quality. Additionally, parenting styles significantly moderated parental modeling, such that an authoritative parenting style in conjunction with modeling healthy eating habits was associated with better adolescent dietary quality. CONCLUSIONS: This work suggests that parental modeling of health behaviours is important; however, it is necessary to consider the broader emotional/relational context into which modeling is expressed since parenting styles moderated these effects. This study provides insight into how parenting styles may alter the effectiveness of parental modeling and highlights the need to account for parenting styles to improve the efficacy of current family-based interventions.

Reliability and validity of a novel tool to comprehensively assess food and beverage marketing in recreational sport settings.

BACKGROUND: Current methods for evaluating food marketing to children often study a single marketing channel or approach. As the World Health Organization urges the removal of unhealthy food marketing in children's settings, methods that comprehensively explore the exposure and power of food marketing within a setting from multiple marketing channels and approaches are needed. The purpose of this study was to test the inter-rater reliability and the validity of a novel settings-based food marketing audit tool. METHODS: The Food and beverage Marketing Assessment Tool for Settings (FoodMATS) was developed and its psychometric properties evaluated in five public recreation and sport facilities (sites) and subsequently used in 51 sites across Canada for a cross-sectional analysis of food marketing. Raters recorded the count of food marketing occasions, presence of child-targeted and sports-related marketing techniques, and the physical size of marketing occasions. Marketing occasions were classified by healthfulness. Inter-rater reliability was tested using Cohen's kappa (κ) and intra-class correlations (ICC). FoodMATS scores for each site were calculated using an algorithm that represented the theoretical impact of the marketing environment on food preferences, purchases, and consumption. Higher FoodMATS scores represented sites with higher exposure to, and more powerful (unhealthy, child-targeted, sports-related, large) food marketing. Validity of the scoring algorithm was tested through (1) Pearson's correlations between FoodMATS scores and facility sponsorship dollars, and (2) sequential multiple regression for predicting "Least Healthy" food sales from FoodMATS scores. RESULTS: Inter-rater reliability was very good to excellent (κ = 0.88-1.00, p < 0.001; ICC = 0.97, p < 0.001). There was a strong positive correlation between FoodMATS scores and food sponsorship dollars, after controlling for facility size (r = 0.86, p < 0.001). The FoodMATS score explained 14% of the variability in "Least Healthy" concession sales (p = 0.012) and 24% of the variability total concession and vending "Least Healthy" food sales (p = 0.003). CONCLUSIONS: FoodMATS has high inter-rater reliability and good validity. As the first validated tool to evaluate the exposure and power of food marketing in recreation facilities, the FoodMATS provides a novel means to comprehensively track changes in food marketing environments that can assist in developing and monitoring the impact of policies and interventions.

Food marketing in recreational sport settings in Canada: a cross-sectional audit in different policy environments using the Food and beverage Marketing Assessment Tool for Settings (FoodMATS).

BACKGROUND: Children's recreational sport settings typically sell energy dense, low nutrient products; however, it is unknown whether the same types of food and beverages are also marketed in these settings. Understanding food marketing in sports settings is important because the food industry often uses the promotion of physical activity to justify their products. This study aimed to document the 'exposure' and 'power' of food marketing present in public recreation facilities in Canada and assess differences between provinces with and without voluntary provincial nutrition guidelines for recreation facilities. METHODS: Food marketing was measured in 51 sites using the Food and beverage Marketing Assessment Tool for Settings (FoodMATS). The frequency and repetition ('exposure') of food marketing and the presence of select marketing techniques, including child-targeted, sports-related, size, and healthfulness ('power'), were assessed. Differences in 'exposure' and 'power' characteristics between sites in three guideline provinces (n = 34) and a non-guideline province (n = 17) were assessed using Pearson's Chi squared tests of homogeneity and Mann-Whitney U tests. RESULTS: Ninety-eight percent of sites had food marketing present. The frequency of food marketing per site did not differ between guideline and non-guideline provinces (median = 29; p = 0.576). Sites from guideline provinces had a significantly lower proportion of food marketing occasions that were "Least Healthy" (47.9%) than sites from the non-guideline province (73.5%; p < 0.001). Use of child-targeted and sports-related food marketing techniques was significantly higher in sites from guideline provinces (9.5% and 10.9%, respectively), than in the non-guideline province (1.9% and 4.5% respectively; p values < 0.001). It was more common in the non-guideline province to use child-targeted and sports-related techniques to promote "Least Healthy" items (100.0% and 68.4%, respectively), compared to the guideline provinces (59.3% and 52.0%, respectively). CONCLUSIONS: Recreation facilities are a source of children's exposure to unhealthy food marketing. Having voluntary provincial nutrition guidelines that recommend provision of healthier foods was not related to the frequency of food marketing in recreation facilities but was associated with less frequent marketing of unhealthy foods. Policy makers should provide explicit food marketing regulations that complement provincial nutrition guidelines to fulfill their ethical responsibility to protect children and the settings where children spend time.
