Describing the views of Canadian post-secondary students in health-related disciplines on the recognition of obesity as a chronic disease

OBJECTIVE

This cross-sectional study examined students' perspectives on the ramifications of obesity being recognized as a chronic disease in Canada.

PARTICIPANTS

Undergraduate and graduate students (n = 150) in health-related programs at a major Canadian university.

METHODS

An online survey featured open-ended questions to capture student perspectives on recognizing obesity as a disease. Data were evaluated using content analysis methods.

RESULTS

Positive themes identified included: (a) treatment accessibility; (b) improved healthcare provider attitudes; (c) de-stigmatization of obesity; (d) promotion of health behaviors; and (e) greater research/funding. Negative themes included potential: (a) healthcare system burdens; (b) perpetuation of obesity stigma; (c) medicalization of obesity; and (d) de-emphasis on modifiable risk factors as contributing to obesity.

CONCLUSIONS

There is a need to increase students' understanding of the multifaceted nature of obesity and the prevention of obesity-related stigma within healthcare. Findings may inform post-secondary health curricula and obesity initiatives.

Factors that contributed to Ontario adults' mental health during the first 16 months of the COVID-19 pandemic: a decision tree analysis

The COVID-19 pandemic has negatively impacted the mental health of individuals globally. However, less is known about the characteristics that contributed to some people having mental health problems during the pandemic, while others did not. Mental health problems can be understood on a continuum, ranging from acute (e.g., depression following a stressful event) to severe (e.g., chronic conditions that disrupt everyday functioning). Therefore, the purpose of this article was to generate profiles of adults who were more or less at risk for the development of mental health problems, in general, during the first 16-months of the COVID-19 pandemic in Ontario, Canada. Data were collected via online surveys at two time points: April-July 2020 and July-August 2021; 2,188 adults (Mage = 43.15 years; SD = 8.82) participated. Surveys included a demographic questionnaire and four previously validated tools to measure participants' mental health, subjective wellbeing, physical activity and sedentary behaviour, and sleep. A decision tree was generated at each time point for those with mental health problems, and those with no mental health problems. Results showed that subjective wellbeing was the biggest contributor to mental health status. Characteristics associated with no mental health problems among adults included having good wellbeing, being a good sleeper (quantity, quality, and patterns of sleep), and being over the age of 42. Characteristics associated with mental health problems included having poor wellbeing and being a poor sleeper. Findings revealed that specific characteristics interacted to contribute to adults' mental health status during the first 16 months of the COVID-19 pandemic. Given that wellbeing was the biggest contributor to mental health, researchers should focus on targeting adults' wellbeing to improve their mental health during future health crises.

The impact of smartphone app-based interventions on adolescents' dietary intake: a systematic review and evaluation of equity factor reporting in intervention studies

CONTEXT

Adolescence is a critical stage for improving nutrition. The popularity of smartphones makes them an ideal platform for administering interventions to adolescents. A systematic review has yet to assess the impact of smartphone app-based interventions exclusively on adolescents' dietary intake. Furthermore, despite the impact of equity factors on dietary intake and the claim for mobile health of increased accessibility, there is minimal research on the reporting of equity factors in the evaluation of smartphone app-based nutrition-intervention research.

OBJECTIVES

This systematic review examines the effectiveness of smartphone app-based interventions on adolescents' dietary intake and the frequency with which equity factors and statistical analyses specific to equity factors are reported in these intervention studies.

DATA SOURCES

Databases (ie, Scopus, CINAHL, EMBASE, MEDLINE, PsycINFO, ERIC, and Cochrane Central Register for Randomized Control Trials) were searched for studies published from January 2008 to October 2022. Smartphone app-based intervention studies that were nutrition focused, evaluated at least 1 dietary intake variable, and included participants with a mean age between 10 and 19 years were included. All geographic locations were included.

DATA EXTRACTION AND ANALYSIS

Study characteristics, intervention results, and reported equity factors were extracted. Because of the heterogeneity of dietary outcomes, findings were reported as a narrative synthesis.

CONCLUSION

In total, 3087 studies were retrieved, 14 of which met the inclusion criteria. Eleven studies reported a statistically significant improvement in at least 1 dietary outcome because of the intervention. Reporting of at least 1 equity factor across articles' Introduction, Methods, Results, and Discussion sections was minimal (n = 5), and statistical analyses specific to equity factors were rare, occurring in only 4 of the 14 included studies. Future interventions should include a measurement of intervention adherence and report the impact of equity factors on the effectiveness and applicability of interventions for equity-deserving groups.

Association Between Children's and Parents' Physical Activity During the COVID-19 Pandemic: A Cross-Lagged Analysis

BACKGROUND

COVID-19 caused closures of movement supporting environments such as gyms and schools in Canada. This study evaluated the association between Ontario parents' and children's physical activity levels across time during COVID-19, controlling for variables that were identified as significant predictors of children's and parents' physical activity (e.g., children's age, parents' employment status).

METHODS

Parents (n = 243; mean age = 38.8 y) of children aged 12 and under (n = 408; mean age = 6.3 y) living in Ontario, Canada completed 2 online surveys, the first between August and December 2020 and the second between August and December 2021. At baseline, parents were asked to recall prepandemic physical activity levels. To determine the association between parent and child physical activity during COVID-19, a cross-lagged model was estimated to determine the cross-sectional and longitudinal associations between parents' and children's physical activity across time.

RESULTS

Bivariate associations revealed that parents' and children's physical activity levels were significantly related during lockdown and postlockdown but not prelockdown. The autoregressive paths from prelockdown to during lockdown were significant for children (β = 0.53, P < .001) and parents (β = 1.058, P < .001) as were the autoregressive paths from during lockdown to postlockdown for children (β = 0.61, P < .001) and parents (β = 0.48, P < .001). In fully adjusted models, the cross-lagged association between parents' physical activity prelockdowns was significantly positively associated with their children's physical activity during lockdowns (β = 0.19, P = .013).

CONCLUSIONS

Resources are needed to ensure that children and parents are obtaining sufficient levels of physical activity, particularly during a pandemic.

Parents' attitudes regarding their children's play during COVID-19: Impact of socioeconomic status and urbanicity

Objectives

The COVID-19 pandemic has had a profound impact on the daily routines of parents and children. This study explored the influence of socioeconomic status (SES) and urbanicity on parents' attitudes toward their children's active play opportunities 6 months and 1.5 years into COVID-19.

Methods

A sample of 239 Ontario parents of children aged 12 and younger completed two online surveys (August-December 2020; 2021) to assess parents' intentions, beliefs, and comforts concerning their child's eventual return to play, in addition to various sociodemographic and physical activity variables. Descriptive analyses were run as well as an exploratory factor analysis (EFA) was conducted to group the 14 attitude items into subscales for analysis, to ensure reliability and validity of attitude measures.

Results

In general, parents in communities with more urban features (e.g., densely populated areas), single-parents, full-time employed parents, and parents with lower-incomes were more hesitant to return their children to active play during the pandemic.

Conclusion

Findings from this work highlight SES and urbanicity disparities that continue to exist during COVID-19.

Implementation models and frameworks used to guide community-based physical activity programs for children: a scoping review

BACKGROUND

The implementation of community-based programs is key to effective, sustainable initiatives that can support population-level changes in children's physical activity. The purpose of this scoping review was to explore the implementation models and frameworks used to develop (process models), explore (determinant frameworks), and/or evaluate (evaluation frameworks) community-based physical activity programs for children. Also, the foundational components of the implementation models and frameworks and practical application in real-world settings were described.

METHODS

The methodological framework developed by Arksey and O'Malley (2005) and the updated recommendations from Levac, Colquhoun and O'Brien (2010) were used to search, identify, and summarize applicable studies. This review also met the requirements in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Reviews Checklist (PRISMA-ScR). A detailed search of six databases and three academic journals was conducted. Information about the article, the program, and the implementation model/framework were extracted and summarized.

RESULTS

The search retrieved 42,202 articles, of which 27 met the inclusion criteria. Eleven process models, one determinant framework, and two evaluation frameworks were identified. Nineteen components were developed from the models and frameworks. Tailoring, situational analysis, and element identification were common components among the identified models and frameworks.

CONCLUSIONS

Since the execution of interventions is vital for creating successful health-promoting initiatives, researchers and program developers should consider using implementation models and frameworks to guide their community-based physical activity programs. Further research examining the application of new and existing implementation models and frameworks in developing, exploring, and evaluating community-level programs is warranted.

'When you give kindness out, you get it back ten times more': Ontario adults' prosocial behaviour during the first 16 months of the COVID-19 pandemic

The COVID-19 pandemic has provided a collective opportunity to engage in prosocial behaviours, including kindness; however, little is known about the long-term impacts of the pandemic on such behaviours. As a part of a larger study (Health Outcomes for Adults During and Following the COVID-19 Pandemic), the purpose of this mixed methods research was two-fold: (1) to quantitatively explore adults' prosocial behaviour over time during the first 16 months of the pandemic in Ontario, Canada (April 2020-August 2021); and, (2) to more deeply explore, via focus groups, a sub-sample of Ontario adults' lived experiences of prosocial behaviour (assessed March 2022). A total of 2,188 participants were included in this study, with the majority of participants identifying as female (89.5%). At three time points, participants completed online questionnaires which included demographics, Prosocialness Scale for Adults, and three global kindness questions. A subset of participants (n = 42) also participated in one of six focus groups exploring their experiences of prosocial behaviour during the pandemic. A series of one-way repeated measures ANOVAs revealed that participants' self-reported prosocial behaviour increased significantly over time, while participants' awareness of kindness, engagement in acts of kindness, and view of kindness as crucial significantly decreased. Thematic analysis revealed three main themes: (1) shift in prosocial behaviour during the pandemic; (2) kindness from various perspectives; and, (3) prosocial burnout. This study provides insight into the longer-term effects of the pandemic on adults' prosocial behaviours and should be leveraged to help understand how individuals respond in times of crises.

Development of a Physical Activity and Sedentary Behaviour Policy for Canadian Childcare Settings: A Delphi Study

This study aimed to obtain consensus on physical activity (PA) and sedentary behaviour (SB) policy items for use in Canadian childcare settings. Purposeful sampling of Canadian experts in PA/SB (n = 19) and Early Childhood Education (ECE; n = 20) was used to form two distinct (i.e., PA/SB and ECE) panels for a 3-round Delphi study. In round 1, the PA/SB experts suggested their top 10 items for a Canadian childcare PA/SB policy. Policy items were then pooled to generate a list of 24 unique items. In round 2, experts in both panels rated the importance of the 24 policy items using a 7-point Likert scale (i.e., 1 = Not at all important to 7 = Extremely important). The ECE panel was also asked to report on the feasibility of the policy items using a 4-point Likert scale (i.e., 1 = Not at all feasible to 4 = Very feasible). Policy items that received an interquartile deviation (IQD) score of ≤ 1 (indicating consensus) and a median score of ≥ 6 (indicating importance) in both panels were considered shared priorities. In round 3, members of both panels re-rated the importance of the policy items that did not achieve consensus among their respective panel in round 2 and were asked to order items based on importance. Descriptive statistics were used to assess feasibility of policy items, and differences in panel ratings were quantified using Mann Whitney U tests. Consensus was achieved for 23 policy items in the PA/SB panel and 17 items in the ECE panel. Overall, 15 shared priorities were identified (e.g., provide 120 min of outdoor time per day, sedentary behaviour should not be used as a punishment), and six policy items exhibited a statistical difference in ratings across panels. Members of the ECE panel indicated that the policy item, "children should be permitted to go outside whenever they want, for as long as they want" (M = 1.78; SD = 0.65) was lowest in terms of feasibility, and the policy item, "children should receive opportunities to engage in both unstructured and structured physical activity opportunities daily" (M = 3.89; SD = 0.32) was the most feasible for daily implementation. Findings from this study can inform the development of an expert-generated and feasibility-informed institutional PA/SB policy for use in Canadian childcare settings.

Using the RE-AIM framework to evaluate the feasibility of a parent-focused intervention targeting childhood obesity

BACKGROUND

Childhood obesity remains a serious public health concern. Community-based childhood obesity treatment interventions have the potential to improve health behaviors and outcomes among children, but require thorough evaluation to facilitate translation of research into practice. The purpose of the current study was to determine the feasibility of a community-based, parent-focused childhood obesity intervention ("C.H.A.M.P. Families") using the RE-AIM framework, an evaluation tool for health interventions.

METHODS

A single-group, non-randomized, repeated measures feasibility study was conducted. Participants (n = 16 parents/caregivers of 11 children with obesity) completed a 13-week parent-focused education intervention. The intervention consisted of three main components: (a) eight group-based (parent-only) education sessions; (b) eight home-based (family-centered) activities; and (c) two group-based follow-up support sessions for parents and children. The five dimensions of RE-AIM-reach, effectiveness, adoption, implementation, and maintenance-were assessed using various measures and data sources (e.g., child, parent/caregiver, costing, census) obtained throughout the study period. Outcome variables were measured at baseline, mid-intervention, post-intervention, and at a 6-month follow-up.

RESULTS

Overall, the C.H.A.M.P. Families intervention reached approximately 0.09% of eligible families in London, Ontario. Despite the small number, participants were generally representative of the population from which they were drawn, and program participation rates were high (reach). Findings also suggest that involvement in the program was associated with improved health-related quality of life among children (effectiveness/individual-level maintenance). In addition, the intervention had high fidelity to protocol, attendance rates, and cost-effectiveness (implementation). Lastly, important community partnerships were established and maintained (adoption/setting-level maintenance).

CONCLUSIONS

Based on a detailed and comprehensive RE-AIM evaluation, the C.H.A.M.P. Families intervention appears to be a promising parent-focused approach to the treatment of childhood obesity.

Parent-Reported Changes in Ontario Children's Physical Activity Levels during the COVID-19 Pandemic

The COVID-19 pandemic resulted in closures of physical-activity-supporting environments, including playgrounds, outdoor recreation facilities (e.g., basketball courts), and community centers, which impacted children's movement opportunities. This study evaluated changes in Ontario children's physical activity levels during the COVID-19 pandemic and explored the impact of family sociodemographic markers on children's activity. Parents (n = 243; M_age = 38.8 years) of children aged 12 and under (n = 408; M_age = 6.7 years) living in Ontario, Canada, completed two online surveys between August and December 2020 (survey 1) and August and December 2021 (survey 2). Generalized linear mixed-effects models were used to estimate changes in the proportion of children who accumulated 60 min of physical activity per day pre-lockdown, during lockdown, and post-lockdown in Ontario. Results revealed a significant non-linear trajectory whereby the proportion of children achieving 60 min of physical activity per day pre-lockdown (63%) declined during lockdown (21%) and then increased post-lockdown (54%). Changes in the proportion of children engaging in 60 min of daily physical activity were moderated by several demographic variables. Efforts are needed to provide parents of young children with a wider variety of resources to ensure children are obtaining sufficient levels of physical activity regardless of the presence of community lockdowns.

Children's Physical Activity during COVID-19 in Ontario, Canada: Parents' Perspectives

The COVID-19 pandemic has had a large influence on children's physical activity (i.e., play and sport) opportunities. The purpose of this study was to describe parents' perspectives of their children's (ages 0-12) physical activity experiences during the pandemic (i.e., since the onset in March 2020 until follow-up survey completion date [between August to December 2021]). As part of the 'Return to Play' study conducted in Ontario, Canada, two-parent report surveys were completed online via Qualtrics. Surveys measured parents' perspectives regarding their children's physical activity since the onset of the pandemic (n = 17 items) and collected demographic information (n = 16 items). Open-ended questions were included to gather a rich understanding of parents' experiences (i.e., supports, challenges) with facilitating their children's physical activity. Descriptive statistics were calculated to describe parents' perspectives of their children's physical activity experiences and to determine parent demographics. Open-ended questions were analyzed via deductive content analysis. Parents (n = 382) reported that they noticed behavior changes in their children because of the pandemic (65.9%), and most (73.7%) reported challenges with supporting their children's activity during periods when public health measures were in place. Many parents (44.5%) stated that their children asked about returning to play/sport more than three times per week during periods when play/sport facilities were closed in Ontario. Qualitative data identified common supports parents used (e.g., getting active outdoors, forming mini social 'bubbles'), and challenges they faced (e.g., work, children's increased screen time, and home schooling), pertaining to their children's physical activity.

Association between childcare movement behaviour compositions with health and development among preschoolers: Finding the optimal combinations of physical activities and sedentary time

Little is known about how wake-time movement behaviour compositions while in childcare relate to children's health and development. This study aimed to use compositional analysis to examine how childcare movement behaviour compositions were associated with standardised body mass index (zBMI) and physical and psychosocial functioning among children in the preschool setting. A total of 405 preschoolers wore accelerometers during childcare hours to measure their moderate-to-vigorous physical activity (MVPA), light intensity physical activity (LPA) and sedentary time. Compositional regression, isotemporal substitution models, and the "Goldilocks" approach was used to examine how wake-time childcare movement behaviour compositions related to each of the outcomes. Engaging in greater LPA relative to MVPA and sedentary time was associated with higher BMI z-scores, replacing sedentary time or time spent in MVPA with LPA was associated with greater physical functioning, and spending more time in sedentary behaviours relative to overall physical activity was related with greater psychosocial functioning. It is not clear what the optimal wake-time movement behaviour composition while in childcare is for health and development; however, LPA and sedentary time while in childcare may have some benefits. More research is needed to aid the development of childcare-specific guidelines for physical activity and sedentary behaviours.

Parents' Attitudes Regarding Their Children's Play and Sport During COVID-19

The COVID-19 pandemic and associated public health measures have interrupted the daily routines of parents and children. The purpose of this study was to explore parents' attitudes regarding their children's play/sport during COVID-19. A secondary objective was to explore the influence of parent demographics and parent-reported physical activity levels and risk tolerance on these attitudes. Ontario parents of children aged 12 and younger completed an online survey (August-December 2020) that assessed their attitudes (grouped by support, safety and socialization-related attitudes; n = 14 items) regarding their child(ren)'s play/sport, their physical activity levels (n = 2 items), and demographic details (n = 16 items). Two open-ended items were used to gather a deeper understanding of attitudes. Parents' tolerance for risk was measured via the validated Tolerance of Risk in Play Scale. Descriptive statistics were calculated to describe attitudes and risk tolerance. Least Absolute Shrinkage and Selection Operator regressions were conducted to examine factors influencing parents' attitudes. Multiple linear models were computed using the identified predictors for each attitude category. Deductive content analysis was undertaken on open-ended responses. Participants (n = 819) reported the highest scores for safety-related attitude items (M = 3.54, SD = .63) followed by socialization and support, which all influenced attitudes regarding children's play/sport (p < .05). Demographics and parents' physical activity levels were identified as important predictors of parents' attitudes. Qualitative data revealed that parents had mixed levels of comfort with respect to their children's return to play/sport. Findings from this study reveal that increased support is needed to guide future play/sport decision-making.

Experiences of At-Risk Women in Accessing Breastfeeding Social Support During the Covid-19 Pandemic

BACKGROUND

With strict public health measures implemented in March 2020 due to the COVID-19 pandemic, many breastfeeding parents, who are within an at-risk population, have experienced limited formal and/or informal breastfeeding social support. In the Canadian context, the experiences of these women is unknown.

RESEARCH AIM

To explore the experiences of at-risk postpartum breastfeeding women in accessing formal and informal breastfeeding social support during the COVID-19 pandemic.

METHODS

This was a prospective, longitudinal interpretive description study using mixed methods. Data were gathered using an online survey and one 52-112-min semi-structured interview at 12-weeks postpartum. At-risk breastfeeding participants were those who lack social support and had at least one of the following: age < 25 years; experiencing or had experienced intimate partner violence; or of low income. We sought participants' experiences of accessing breastfeeding social support during the first few months of the COVID-19 pandemic/lockdown. Seven participants completed the survey and the interview.

RESULTS

Participants identified that the COVID-19 pandemic created barriers to accessing formal and informal breastfeeding social support, which stemmed from public health restrictions and difficulties communicating online with families and healthcare providers. Additionally, participants identified that the COVID-19 pandemic/lockdowns facilitated feelings of connectedness, protection, and resiliency.

CONCLUSION

We provide preliminary insight into the experiences of trying to access breastfeeding social support during the COVID-19 pandemic. Future researchers should seek to prioritize improved communication and resources in supporting breastfeeding during COVID-19 and future pandemics/lockdowns.

Implementation of an e-Learning course in physical activity and sedentary behavior for pre- and in-service early childhood educators: Evaluation of the TEACH pilot study

Background

Childcare-based physical activity (PA) and sedentary behavior (SB) interventions have traditionally used in-person training to supplement early childhood educators’ (ECEs) knowledge and confidence to facilitate physically active programming for the children in their care. However, this method of delivery is resource-intensive and unable to reach a high number of ECEs. The purpose of the Training pre-service EArly CHildhood educators in PA (TEACH) pilot study was to test the implementation (e.g., fidelity, feasibility, acceptability) of an e-Learning course targeting PA and SB among a sample of pre-service (i.e., post-secondary students) and in-service (i.e., practicing) ECEs in Canada.

Methods

A pre-/post-study design was adopted for this pilot study, and implementation outcomes were assessed cross-sectionally at post-intervention. Pre-service ECEs were purposefully recruited from three Canadian colleges and in-service ECEs were recruited via social media. Upon completing the e-Learning course, process evaluation surveys (n = 32 pre-service and 121 in-service ECEs) and interviews (n = 3 pre-service and 8 in-service ECEs) were completed to gather ECEs’ perspectives on the e-Learning course. Fidelity was measured via e-Learning course metrics retrieved from the web platform. Descriptive statistics were calculated for quantitative data, and thematic analysis was conducted to analyze qualitative data.

Results

Moderate-to-high fidelity to the TEACH study e-Learning course was exhibited by pre-service (68%) and in-service (63%) ECEs. Participants reported that the course was highly acceptable, compatible, effective, feasible, and appropriate in complexity; however, some ECEs experienced technical difficulties with the e-Learning platform and noted a longer than anticipated course duration. The most enjoyed content for pre- and in-service ECEs focused on outdoor play (87.5% and 91.7%, respectively) and risky play (84.4% and 88.4%, respectively).

Conclusions

These findings demonstrate the value of e-Learning for professional development interventions for ECEs. Participant feedback will be used to make improvements to the TEACH e-Learning course to improve scalability of this training.

Not so sweet dreams: adults' quantity, quality, and disruptions of sleep during the initial stages of the COVID-19 pandemic

OBJECTIVES

The purpose of this study was to investigate Ontario adults' reported sleep quantity, quality, and disturbances during the early months of the COVID-19 pandemic (April-July 2020).

METHODS

As part of a larger, chronic disease-focused, and ongoing longitudinal study designed to explore Ontario adults' health and wellness-related behaviors during the pandemic, participants completed an online survey that included demographic information and the Pittsburgh Sleep Quality Index (PSQI). The PSQI consists of 19 items, one of which is open-ended, designed to assess an individual's quantity, quality, and patterns of sleep on seven domains (ie, subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction over the last month). Summative content analysis was used to analyze responses to the open-ended question regarding participants' sleep disturbances.

RESULTS

This study included 2192 individuals, 85% of whom slept 6+ hours/night. The mean global PSQI score was 7.57, out of a possible 21 (SD = 4.09). The self-reported sleep disturbances of largest concern were: (1) general fear/anxiety/worry (n = 203); (2) children (n = 167); (3) mind wandering/overthinking (n = 118); (4) pain/injury (n = 78); (5) partner (n = 78); and (6) fear/anxiety/stress related to COVID-19 (n = 74).

CONCLUSION

The global PSQI score was indicative of poor sleep quality, and Ontario adults experienced a number of sleep disturbances during early days of the COVID-19 pandemic. These findings are noteworthy as sleep is a crucial component in positive health and wellbeing.

Change in pre- and in-service early childhood educators’ knowledge, self-efficacy, and intentions following an e-learning course in physical activity and sedentary behaviour: a pilot study

Background

Early childhood educators (ECEs) are the primary daytime role models for many young children, and are responsible for facilitating physical activity (PA) opportunities and minimizing sedentary behaviour (SB) in childcare. However, they have reportedly received little related education in their pre-service training. The purpose of the Training pre-service EArly CHildhood educators in physical activity (TEACH) pilot study was to explore changes in pre- and in-service ECEs’ knowledge, self-efficacy, behavioural intention, and perceived behavioural control following the TEACH e-Learning course in PA and SB.

Methods

Pre-service ECEs were purposefully recruited from three Canadian colleges, while in-service ECEs were recruited via social media. A pre-post study design was used. ECEs completed two online surveys; one prior to, and one immediately following the completion of the TEACH e-Learning course (~ 5 h). Descriptive statistics were reported, and McNemar Chi-Square tests and paired samples t-tests were used to examine changes in ECEs’ question-specific, and total knowledge scores, respectively. Wilcoxon Signed Ranks tests were employed to examine changes in self-efficacy, behavioural intention, and perceived behavioural control.

Results

Both pre- (n = 32) and in-service (n = 121) ECEs significantly increased their total knowledge scores from pre- to post-course completion (p < .05*). Significant positive changes in self-efficacy (p < .025*), behavioural intention (p < .007*), and perceived behavioural control (p < .007*) were demonstrated by in-service ECEs following course completion, while only select composite scores within these tools were significant among pre-service ECEs.

Conclusions

These findings provide preliminary evidence of the potential efficacy of the e-Learning course at improving ECEs’ knowledge, self-efficacy, behavioural intention, and perceived behavioural control to support PA and minimize SB in childcare. Following the success of the pilot study, testing the effectiveness of the TEACH e-Learning course on a larger scale, with a comparison group, is warranted prior to recommending broader dissemination of the training in pre-service ECE programs and for in-service ECE professional learning.

Children and parents' perspectives of the impact of the COVID-19 pandemic on Ontario children's physical activity, play, and sport behaviours

Background

The COVID-19 pandemic and associated public health measures have resulted in the closure of many physical activity-supporting facilities. This study examined Ontario parents’ and children’s perspectives of COVID-19’s impact on children’s physical activity behaviours, return to play/sport during COVID-19, as well as barriers/facilitators to getting active amid extended closures of physical activity venues.

Methods

Parents/guardians of children aged 12 years and under living in Ontario, Canada were invited to participate in an interview. 12 parent/guardian and 9 child interviews were conducted via Zoom between December 2020 – January 2021, were audio-recorded, and transcribed verbatim. Thematic content analysis was undertaken to identify pronounced themes.

Results

Themes for both parent and child interviews fell into one of three categories: 1) barriers and facilitators for getting children active amid COVID-19 closures of physical activity-supporting facilities; 2) changes in children’s activity levels; and, 3) perspectives on return to play/sport during and post-pandemic. Various subthemes were identified and varied between parents and children. The most common facilitator for dealing with children’s inactivity voiced by parents/guardians was getting active outdoors. Parents/guardians noted their willingness to have their children return to play/sport in the community once deemed safe by public health guidelines, and children’s willingness to return stemmed primarily from missing their friends and other important authority figures (e.g., coaches) and sporting events (e.g., tournaments).

Conclusions

Findings from this study could inform families of feasible and realistic strategies for increasing children’s physical activity during community closures, while also providing public health experts with information regarding what supports, or infrastructure might be needed during future lockdown periods and/or pandemics.

Ontario adults' health behaviors, mental health, and overall well-being during the COVID-19 pandemic

BACKGROUND

Public health measures such as physical distancing and work-from-home initiatives have been implemented to slow the spread of COVID-19. These measures may also be associated with unhealthy lifestyle behaviors, which could be particularly problematic for those already at highest risk for losing years of healthy life due to chronic disease (i.e., 30-59-year-olds). The purpose of this paper is two-fold: (1) to provide an overview of Ontario adults' health behaviors (i.e., physical activity, sedentary behaviors, and dietary intake), mental health, and well-being during the first few months of the COVID-19 pandemic (April-July 2020); and (2) to explore the difference between physical activity and various health behaviors (i.e., well-being, mental health, and dietary intake).

METHODS

As a part of a larger, longitudinal study, participants completed an online survey that included demographic information, the Global Physical Activity Questionnaire, Starting the Conversation, the Mental Health Inventory, and the Personal Wellbeing Index-Adult. Data analyses involved computing measures of central tendency and dispersion for demographic characteristics and tools followed by descriptive statistics. Separate independent t-tests were conducted to investigate the difference between physical activity status and well-being, mental health, and dietary intake.

RESULTS

A total of 2157 Ontarians completed an online survey. Descriptive statistics indicated that respondents met physical activity and sedentary behavior guidelines, reported double the amount of recommended recreational screen time, practiced moderately healthy dietary behaviors, experienced mental health problems, and scored below "normal" in some well-being domains.

CONCLUSION

As the end of the COVID-19 pandemic is currently unknown, its associated restrictions and society changes may influence adults' behaviors in both the short- and longer-term. As such, our findings might provide immediate insight into the development of timely and evidence-informed health promotion and disease prevention strategies for Canadians, which could support adults' health behaviors, mental health, and well-being during the COVID-19 pandemic and other, future pandemics.

Sedentary time among undergraduate students: A systematic review

To systematically review and synthesize all relevant literature to assess the range of average daily sedentary time (ST) of undergraduate students enrolled in university and college programs across the world. Methods: Published, peer-reviewed articles were included if they: (a) were in English; (b) had a study population that consisted entirely of undergraduate students; (c) reported a daily or weekly ST for undergraduate students; and (d) included a measure of ST using a valid sedentary behavior questionnaire or accelerometers. Results: Twenty-three studies were included in the review. A wide range of ST (0.75 to 14.35 hours per day) was reported. Mean ST as measured by domain-specific questionnaires and accelerometers was 11.10 hours per day and 10.69 hours per day, respectively. Conclusion: Findings suggest that some undergraduate students participate in high levels of ST. Additional research, as well as interventions focused on reducing ST among postsecondary students, are needed.

Implementation Adherence and Perspectives of the Childcare PhysicaL ActivitY (PLAY) Policy: A Process Evaluation

The Childcare PhysicaL ActivitY (PLAY) policy was an evidence-informed, eight-item institutional-level policy document targeting children’s physical activity, outdoor play, and sedentary time. Nine childcare centers in London, Ontario, participated in this cluster, randomized controlled trial. Early Childhood Educators allocated to the experimental group, from five childcare centers in London, Ontario, implemented the policy for young children (18 months to 4 years) for 8 weeks and documented adherence to each policy item (i.e., dose) in daily logs. Program evaluation surveys (n = 21) and interviews (n = 10) were completed postintervention to assess Early Childhood Educators’ perspectives of feasibility, context, enjoyment, communication between researchers and childcare staff, and likelihood of future implementation. Descriptive statistics were calculated, and thematic analysis was conducted. Adherence to policy items ranged from 16.5% (for delivery of shorter, more frequent outdoor periods) to 85.9% (for delivery of unstructured/child-directed play). Participants reported effective communication between the research team and childcare centers (0 = not at all effective to 5 = very effective; M = 4.20; SD = 0.83) but noted that they were unlikely to continue the implementation of more frequent outdoor periods (0 = not at all likely to 5 = extremely likely; M = 2.19; SD = 1.21). Interview themes included weather as a prominent barrier and the use of verbal prompts as a solution for implementing the policy. As this was a small and short-term intervention, this pilot study offers important insight on larger scale policy interventions aimed at increasing physical activity and minimizing sedentary time among children enrolled in childcare.

Training may enhance early childhood educators' self-efficacy to lead physical activity in childcare

Background

Early childhood educators (ECEs) play a critical role in promoting physical activity (PA) among preschoolers in childcare; thus, PA-related training for ECEs is essential. The Supporting PA in the Childcare Environment (SPACE) intervention incorporated: 1. shorter, more frequent outdoor play sessions; 2. provision of portable play equipment; and, PA training for ECEs. An extension of the SPACE intervention (the SPACE-Extension) incorporated only the shorter, more frequent outdoor play periods component of the original SPACE intervention. The purpose of this study was to explore the individual impact of these interventions on ECEs’ PA-related self-efficacy and knowledge.

Methods

ECEs from the SPACE (n = 83) and SPACE-Extension (n = 31) were administered surveys at all intervention time-points to assess: self-efficacy to engage preschoolers in PA (n = 6 items; scale 0 to 100); self-efficacy to implement the intervention (n = 6 items); and, knowledge of preschooler-specific PA and screen-viewing guidelines (n = 2 items). A linear mixed effects model was used to analyze the impact of each intervention on ECEs’ self-efficacy and knowledge and controlled for multiple comparison bias.

Results

The SPACE intervention significantly impacted ECEs’ self-efficacy to engage preschoolers in PA for 180 min/day (main effect), and when outdoor playtime was not an option (interaction effect). Further, the interaction model for ECEs’ knowledge of the total PA guideline for preschoolers approached significance when compared to the main effects model. Participants within the SPACE-Extension did not demonstrate any significant changes in self-efficacy or knowledge variables.

Conclusions

Findings from this study highlight the benefit of ECE training in PA with regard to fostering their PA-related self-efficacy and knowledge. Future research should explore the impact of PA training for ECEs uniquely in order to determine if this intervention component, alone, can produce meaningful changes in children’s PA behaviours at childcare.

Fish growth rates and lake sulphate explain variation in mercury levels in ninespine stickleback (Pungitius pungitius) on the Arctic Coastal Plain of Alaska

Mercury concentrations in freshwater food webs are governed by complex biogeochemical and ecological interactions that spatially vary and are often mediated by climate. The Arctic Coastal Plain of Alaska (ACP) is a heterogeneous, lake-rich landscape where variability in mercury accumulation is poorly understood. Earlier research indicated that the level of catchment influence on lakes varied spatially on the ACP, and affected mercury accumulation in lake sediments. This work sought to determine drivers of spatial variation in mercury accumulation in lake food webs on the ACP. Three lakes that were a priori identified as "high catchment influence" (Reindeer Camp region) and three lakes that were a priori identified as "low catchment influence" (Atqasuk region) were sampled, and variability in water chemistry, food web ecology, and mercury accumulation was investigated. Among-lake differences in ninespine stickleback (Pungitius pungitius) length-adjusted methylmercury concentrations were significantly explained by sulphate concentration in lake water, a tracer of catchment runoff input. This effect was mediated by fish growth, which had no pattern between regions. Together, lake water sulphate concentration and fish age-at-size (proxy for growth) accounted for nearly all of the among-lake variability in length-adjusted methylmercury concentrations in stickleback (R²_adj = 0.94, p < 0.01). The percentage of total mercury as methylmercury (a proxy for net Hg methylation) was higher in sediments of more autochthonous, "low catchment influence" lakes (p < 0.05), and in the periphyton of more allochthonous, "high catchment influence" lakes (p < 0.05). The results indicate that dominant sources of primary production (littoral macrophyte/biofilm vs. pelagic phytoplankton) and food web structure (detrital vs. grazing) are regulated by catchment characteristics on the ACP, and that this ultimately influences the amount of methylmercury in the aquatic food web. These results have important implications for predicting future mercury concentrations in fish in lakes where fish growth rates and catchment inputs may change in response to a changing climate.

Perspectives and Impact of a Parent-Child Intervention on Dietary Intake and Physical Activity Behaviours, Parental Motivation, and Parental Body Composition: A Randomized Controlled Trial

Adults and children in Canada are not meeting physical activity guidelines nor consuming sufficient nutrient-rich foods. High engagement in these unhealthy behaviours can lead to obesity and its associated diseases. Parent-child interventions aimed at obesity prevention/treatment have assisted families with making positive changes to their nutrition and physical activity behaviours. Given that the home environment shapes early health behaviours, it is important to target both parents and children when addressing diet and physical activity. One method that has been shown to improve health outcomes is co-active coaching. The current study explored the impact of a three-month co-active coaching and/or health education intervention on the dietary intake and physical activity behaviours of parents with overweight/obesity and their children (ages 2.5-10; of any weight). Body composition (i.e., body mass index [BMI] and waist circumference), changes in parental motivation with respect to physical activity and dietary behaviours, and parental perceptions of program improvements were collected. A concurrent mixed methods study comprised of a randomized controlled trial and a descriptive qualitative design was utilized. Fifty parent-child dyads were recruited and randomly assigned to the control (n = 25) or intervention (n = 25) group. Assessments were completed at baseline, mid-intervention (six weeks), post-intervention (three months), and six-month follow-up. A linear mixed effects model was utilized for quantitative analysis. Inductive content analysis was used to extract themes from parent interviews. No significant results were observed over time for the dependent measures. Parents in both control and intervention groups reported varied program experiences, including developing changes in perspective, increased awareness of habits, and heightened accountability for making positive changes in themselves, and consequently, their families. Parents also shared barriers they faced when implementing changes (e.g., time, weather, stress). Qualitatively, both groups reported benefitting from this program, with the intervention group describing salient benefits from engaging in coaching. This research expands on the utility of coaching as a method for behaviour change, when compared to education only, in parents with overweight/obesity and their children.
