The Impact of an After-School Physical Activity Program on Children's Physical Activity and Well-Being during the COVID-19 Pandemic: A Mixed-Methods Evaluation Study.

INTRODUCTION: This study evaluated the impact of the Build Our Kids' Success (BOKS) after-school program on children's physical activity (PA) and well-being during the COVID-19 pandemic. METHODS: Program leaders, children, and their parents were recruited from after-school programs in Nova Scotia, Canada, that delivered BOKS programming in Fall 2020. After participating, Grade 4-6 children (n = 14) completed the Physical Literacy Assessment for Youth Self (PLAYself), Physical Activity Questionnaire for Older Children (PAQ-C), the Physical Activity Enjoyment Scale (PACES), and 5 National Institutes of Health (NIH) Patient-Reported Outcomes Measures Information System (PROMIS) scales. Children (n = 7), parents (n = 5), and program leaders (n = 3) completed interviews, which were analyzed for themes inductively. RESULTS: The average PAQ-C score was 2.70 ± 0.48, PLAYself was 68.23 ± 13.12, and PACES was 4.22 ± 0.59 (mean ± SD). NIH PROMIS scores were below standard means (cognitive function, family relationships) or within normal limits (peer relationships, positive affect, and life satisfaction). A thematic analysis of interviews revealed that children's PA levels were impacted by the pandemic and that BOKS positively impacted children's physical well-being and integrated well with school-based activities. CONCLUSIONS: Participation in BOKS provided an overall positive experience and may have mitigated COVID-19-related declines in PA in well-being. The results of this evaluation can inform future physically-active after-school programming.

Regional differences in movement behaviours of children and youth during the second wave of the COVID-19 pandemic in Canada: follow-up from a national study.

OBJECTIVES: Public health restrictions varied by region during the COVID-19 pandemic and reduced opportunities for children to be physically active. The purpose of this study was to assess regional differences in movement behaviours of Canadian children and youth during the second wave of the COVID-19 pandemic. METHODS: A national sample of Canadian parents (n=1568; 58% women) of children and youth (5-17 years of age) completed an online survey. Participants were classified based on region of residence (British Columbia, Prairies, Ontario, Quebec, or Atlantic Canada). Differences in movement and play behaviours (physical activity, outdoor play, sleep, screen time) between children and youth living in different regions were examined. RESULTS: Compared to children and youth in Quebec (the region with the highest COVID-19 prevalence), children and youth in the Prairies (F(1,1563)=9.0, p=0.01) and Atlantic Canada (F(1,1563)=17.1, p<0.001) participated in more moderate-to-vigorous physical activity (MVPA). Compared to Quebec, living in Atlantic Canada increased the odds of meeting the MVPA guideline (odds ratio (OR)=2.1, p=0.02), living in Ontario decreased the odds of meeting the sleep guideline (OR=0.6, p=0.01), and living in Ontario (OR=0.7, p=0.04) or Atlantic Canada (OR=0.6, p=0.049) decreased the odds of meeting the screen time guideline. Children and youth in Atlantic Canada demonstrated smaller declines in outdoor play than their counterparts in Quebec. CONCLUSION: Movement and play behaviours varied between regions of Canada where the highest COVID-19 prevalence corresponded to lower odds of meeting the physical activity guidelines. Low compliance with 24-hour movement guidelines suggests that regional pandemic recovery plans need to prioritize opportunities for healthy movement.

RéSUMé: OBJECTIFS: Les restrictions sanitaires ont varié d'une région à l'autre durant la pandémie de COVID-19, et elles ont réduit les possibilités pour les enfants d'être actifs. Notre étude visait à évaluer les différences régionales dans les comportements liés au mouvement des enfants et des jeunes canadiens au cours de la deuxième vague de la pandémie. MéTHODE: Un échantillon national de parents canadiens (n = 1 568; 58 % de femmes) d'enfants et de jeunes (5­17 ans) ont répondu à un sondage en ligne. Les participants ont été classés selon leur région de résidence (Colombie-Britannique, Prairies, Ontario, Québec ou Canada atlantique). Les différences dans les comportements liés au mouvement et au jeu (activité physique, jeu à l'extérieur, sommeil, temps d'écran) entre les enfants et les jeunes de différentes régions ont été examinées. RéSULTATS: Comparativement aux enfants et aux jeunes du Québec (la région qui présentait la plus forte prévalence de COVID-19), les enfants et les jeunes des Prairies (F(1,1563) = 9,0, p = 0,01) et du Canada atlantique (F(1,1563) = 17,1, p < 0,001) ont fait plus d'activité physique modérée à vigoureuse (APMV). Comparativement au Québec, le fait de vivre au Canada atlantique a accru la probabilité de respecter les lignes directrices sur l'APMV (rapport de cotes (RC) = 2,1, p = 0,02), le fait de vivre en Ontario a réduit la probabilité de respecter les lignes directrices sur le sommeil (RC = 0,6, p = 0,01), et le fait de vivre en Ontario (RC = 0,7, p = 0,04) ou au Canada atlantique (RC = 0,6, p = 0,049) a réduit la probabilité de respecter les lignes directrices sur le temps d'écran. Les enfants et les jeunes du Canada atlantique ont présenté des baisses moins importantes du jeu à l'extérieur que les enfants et les jeunes du Québec. CONCLUSION: Les comportements liés au mouvement et au jeu ont varié d'une région à l'autre du Canada; là où la prévalence de la COVID-19 était la plus élevée, la probabilité de respecter les lignes directrices sur l'activité physique était la plus faible. La faible conformité aux lignes directrices sur le mouvement sur une période de 24 heures donne à penser que les plans de rétablissement régionaux après la pandémie devront accorder la priorité aux possibilités de mouvement sain.

Parents and Children Should Be More Active Together to Address Physical Inactivity and Sedentary Behaviours.

Increasing rates of physical inactivity and sedentary behaviours among children and the youth are important determinants of chronic disease. Supporting children's participation in organised physical activities like sports has been promoted as a public health strategy to increase physical activity. Evidence shows that successful interventions are family-focused, although research on how parental eating and physical activity behaviours influence children's behaviours is deficient. In this commentary, we argue that interventions for countering physical inactivity and sedentary behaviours should include greater focus on home and social environments, specifically the influence and involvement of parents, siblings, and friends in supporting these health behaviours. We conclude that the design of interventions to prevent chronic diseases in children should also consider more carefully the conditions in which the behaviours of children and their parents occur. This means encouraging parents and children to be active together to address physical inactivity and sedentary behaviours, while being mindful of unintended consequences of focusing on one behaviour over another.

Reimagining healthy movement in the era of the COVID-19 pandemic. / Repenser un rythme favorable à la santé à l'ère de la pandémie de COVID-19.

Does the timing of when children, youth and adults participate in physical activity, sedentary behaviour (e.g. screen time) and sleep matter when it comes to their overall health? This special issue of Health Promotion and Chronic Disease Prevention in Canada includes four papers that present evidence and recommendations on the timing of movement behaviours: three separate systematic reviews exploring the associations between health indicators and the timing of physical activity, sedentary behaviour and sleep; and a commentary that discusses the importance of this evidence in terms of practice, policy and research. This editorial sets the stage for this special issue, reflecting on the challenges posed by COVID-19-related public health restrictions on healthy movement. Perhaps now is the optimal time to reimagine how and when we engage in physical activity, sedentary behaviour and sleep to support our health.

RÉSUMÉ: Est-ce que l'horaire auquel les enfants, les adolescents et les adultes sont actifs, demeurent sédentaires (par exemple devant un écran) et dorment ont une influence sur leur état de santé général? Ce numéro spécial de Promotion de la santé et prévention des maladies chroniques au Canada rassemble quatre articles qui présentent des données probantes et des recommandations concernant l'horaire des comportements en matière de mouvement : trois revues systématiques portant sur les associations entre les indicateurs de l'état de santé et les horaires d'activité physique, de sédentarité et de sommeil et un commentaire sur l'importance de ces données probantes pour les pratiques, les politiques et la recherche. Cet éditorial prépare le terrain pour ce numéro spécial en décrivant les effets des restrictions de santé publique liées à la COVID-19 sur un rythme favorable à la santé. Maintenant semble un moment idéal pour réévaluer de quelle manière et selon quel horaire nous devrions être physiquement actifs, demeurer sédentaires et dormir pour favoriser notre santé.

The Effect of an After-School Physical Activity Program on Children's Cognitive, Social, and Emotional Health during the COVID-19 Pandemic in Nova Scotia.

Children's physical activity participation declined during the COVID-19 pandemic, and these negative changes could lead to longer-term impacts on children's cognitive, social, and emotional health. PURPOSE: To determine parent/caregivers' perceptions of their children's cognitive function, peer and family relationships, life satisfaction, physical activity, sleep, positive affect, and global health, before and after participating in the Build Our Kids' Success (BOKS) programming at after-school programs in Fall 2020. METHODS: Parents of children participating in the BOKS programming at after-school programs in Nova Scotia, Canada, were recruited. At baseline, 159 parents completed the National Institutes of Health (NIH) Patient-Reported Outcomes Measures Information System (PROMIS) parent-proxy questionnaire, and 75 parents completed the measures at follow-up. Independent t-tests were used to determine if there were differences between baseline and follow-up Parent Proxy Questionnaire data. RESULTS: All NIH PROMIS outcome variables at baseline and follow-up were within normal limits (Adjusted T-Scores: 46.67 ± 7.15 to 50.04 ± 7.13). There were no significant differences in life satisfaction (t(188) = -1.05, p = 0.30), family relationships (t(189) = 0.31, p = 0.76), cognitive function (t(199) = -1.16, p = 0.25), peer relationships (t(192) = -1.86, p = 0.06), positive affect (t(195) = 0.25, p = 0.81), global health (t(216) = -0.43, p = 0.67), physical activity (t(202) = 0.787, p = 0.732), sleep disturbance (t(193) = 1.72, p = 0.087), or psychological stress (t(196) = 1.896, p = 0.059), from baseline to follow-up. CONCLUSIONS: Parent-proxy questionnaires suggested that the BOKS programming had a protective effect on children's health behaviours and cognitive, social, and emotional health as values remained within normal limits and were not impacted by the public health restrictions during the second wave of the COVID-19 pandemic in Nova Scotia.

Compassionate Bodies, Compassionate Practice: Navigating Body Image Tensions among Gay Men.

Our purpose in writing this Perspective in Practice is to create awareness about the role of compassion within dietetic practice, particularly the role of compassion for body image tensions. Nine self-identifying gay men were recruited to a photovoice research study that explored their beliefs, values, and practices relating to food and their bodies. Compassion was found as one way to navigate body images tensions. It is not the intent of this article to review all aspects of this research study but to use it as an example to illustrate compassion in dietetics. We suggest that our findings reveal the strength of using compassionate practice within the dietetic profession. In doing so, we call upon dietitians to incorporate compassion into their clinical and client care practices to foster health and healing for all communities, especially among those who struggle with body image tensions.

Picture perfect? Gazing into girls' health, physical activity, and nutrition through photovoice.

Background: Women face contradictions regarding their health: Pressure to be feminine, but also athletic; Criticism for being too sporty or muscular, but equally so for being perceived as lazy or overweight. These complexities are perpetuated through media and discourse. Purpose: Using a feminist post-structural approach and photovoice, this study explored health, physical activity, and nutrition in adolescent girls and young women. Methods: Photovoice enables reflection, promotes dialogue, and sparks change. The process involved conducting a workshop, collecting photos, and participatory analysis sessions, which engaged the participants (n = 7, ages 13-26) in photo selection, contextualization, and codifying. Results: This resulted in three themes: First, (Breaking) Stereotypes, in which participants identified gender norms, conflicts, and contradictions; Second, Emotional Safety, or the contexts in which girls and young women feel confident and comfortable; Finally, Being Outside in Nature emerged as significant. Each theme is supported by quotations and photographs. This work suggests being outside in nature provides important context for girls and young women to feel emotionally safe, such that they may engage in the complex navigation of competing discourses surrounding health.

A Loose Parts Randomized Controlled Trial to Promote Active Outdoor Play in Preschool-aged Children: Physical Literacy in the Early Years (PLEY) Project.

BACKGROUND: The Physical Literacy in the Early Years (PLEY) intervention is a randomized mixed-methods controlled trial focused on embedding loose parts materials into the outdoor play spaces of regulated child care centres across Nova Scotia. The aim is to evaluate the efficacy of the PLEY intervention versus standard regulated childcare practice in influencing thoughts and behaviors of children, parents, and educators. METHODS: Participating early child care centres (n = 19) were randomly assigned to intervention or control sites. Intervention sites received loose parts kits at the beginning of the project while control sites received kits upon project completion. The kits included items such as rocks, tree cookies, balls, wood planks, tubes, tires, ropes, and pulleys. Children (n = 183 at baseline) had their physical activity (accelerometers) and movement skills (TGMD-3 and PGMQ) measured before and after the intervention. All centres provided responses to environmental surveys (Go NAP SACC and Site Context Questionnaire), and educators in intervention sites participated in focus group and photovoice sessions. Educators were also provided with a full day professional development opportunity (plus ongoing mentoring) focused on physical activity, physical literacy, outdoor play, risk-taking, and loose parts. Parents participated in an interview addressing active outdoor play, physical literacy, and attitudes towards risk taking during play. DISCUSSION: This study will provide a better understanding of how integrating loose parts materials into outdoor play spaces impacts children's health, and the impact on educator and parent attitudes, beliefs, and understanding around physical literacy, active outdoor play and risk-taking during play.

Accelerometry-measured physical activity and sedentary behaviour of preschoolers in Nova Scotia, Canada.

The objective of this study was to describe the levels and bouts of physical activity (PA) and sedentary behaviour (SB) among preschoolers in Nova Scotia, Canada, and the proportion meeting PA and step guidelines. Children (75 boys, 49 girls; mean age = 4.2 (range = 3-5 years)) participating in the Physical Literacy in the Early Years (PLEY) study provided data. Average time (minutes, % of day) spent sedentary, in light PA (LPA), moderate-to-vigorous PA (MVPA), and total PA; average frequency; and duration of bouts of MVPA (≥5 min, ≥10 min) and sedentary bouts (≥10 min) per day were determined using published cut-points, using 15-s epochs. The proportion of children meeting PA and step guidelines was determined, and differences by sex explored. Children spent the majority (70.8%) of their day active; nearly all (≥97%) met PA guidelines. Most children met step guidelines on a weekly basis, but not daily. Only LPA differed by sex (greater in girls; p = 0.001). Little time was spent in sustained SB (bouts ≥10 min). Boys had greater and longer bouts of MVPA and spent more of their day in these (p < 0.05). Girls spent less time in sustained SB (p = 0.009). This is the first study to describe the PA and SB of Nova Scotia preschoolers using accelerometry. Findings suggest preschoolers spend the majority of their day active, and that there are sex-related differences in PA and SB, warranting further examination.

Educator perceptions on the benefits and challenges of loose parts play in the outdoor environments of childcare centres.

It is important to consider physical activity and movement in early life to ensure children establish and maintain healthy physical activity patterns. Recent evidence has highlighted the importance of outdoor play and the childcare environment. Active outdoor play, especially free play, supports independence, self-regulation and allows children to explore their world and make decisions. Loose parts or open-ended materials are natural or synthetic resources that can be used in more than one way, allowing children to experiment through play. Incorporating loose parts into play environments creates opportunity for new play experiences. Despite growing evidence supporting loose parts play, the perspectives of childcare providers on the benefits and challenges of this type of play have been overlooked. The purpose of this study was to identify the benefits and challenges of incorporating loose parts play into the outdoor environments of childcare centres, from the perspectives of educators who took part in the Physical Literacy in the Early Years (PLEY) project. PLEY is a larger, mixed methods intervention study with the goal of evaluating a loose parts intervention in early childcare settings. This portion of the project used qualitative description to explore educators' perspectives. Data were collected using focus groups (n = 15) with early childhood educators (n = 3-5 in each group). Thematic analysis was used to identify five themes relating to benefits, and four themes relating to challenges. Benefit themes included: loose parts enable children to take risks; loose parts spark creativity and imagination; loose parts contribute to problem-solving abilities; loose parts cultivate independence and confidence; and loose parts build relationships and leadership. Challenges included: apprehension of loose parts; loose parts as a novelty; sustainability of loose parts; and loose parts present challenges with storage. Overall, we found educators perceived outdoor loose parts play to have multiple social and cognitive benefits for preschool-aged children that are critical for optimal growth and development, and overall health and wellness.

Voluntary nutrition guidelines to support healthy eating in recreation and sports settings are ineffective: findings from a prospective study.

Interventions to support healthy eating among populations are needed to address diet-related chronic disease. Recreation and sport settings are increasingly identified as ideal settings for promoting overall health, particularly for children, through creation of environments that support positive health behaviours. These publicly funded settings typically support health through physical activity promotion. However, the food environment within them is often not reflective of nutrition guidelines. As more jurisdictions release nutrition guidelines in such settings, the purpose of this study was to assess whether voluntary nutrition guidelines, released in 2015 in the Canadian province of Nova Scotia, had any impact on food environments in these settings. Baseline and follow-up audits of food environments were conducted one year before (in 30 facilities) and one year after guideline release (in 27 facilities). Audits involved classifying all foods and beverages within vending machines and concessions as Do Not Sell, Minimum, Moderate, or Maximum nutrition, using criteria provided in the guidelines. The proportion of items within each category was calculated, and differences from pre- to post-guideline release were assessed using Chi-squared statistics. Results indicated limited change in food and beverage provision from pre- to post- guideline release. In fact, from pre- to post-guideline release, the proportion of Do Not Sell vending beverages and concession foods increased significantly, while Maximum concession beverages decreased, suggesting a worsening of the food environment post-guideline release. Findings suggest that voluntary guidelines alone are insufficient to improve food environments in recreation and sport settings. For widespread changes in the food environment of these settings to occur, more attention needs to be paid to reducing social, cultural, political and economic barriers to change (real and perceived) that have been identified in these settings, alongside developing leadership and capacity within facilities, to ensure that positive changes to food environments can be implemented and sustained.

"It is not the diet; it is the mental part we need help with." A multilevel analysis of psychological, emotional, and social well-being in obesity.

In this research, we explored the psychological, emotional, and social experiences of individuals living with obesity, and perceptions of health care providers. We conducted a theoretical thematic analysis using two theoretical frameworks applied to transcripts from a previous qualitative study. Themes from a mental well-being framework were subsequently categorized under five environmental levels of the Social-Ecological Model (SEM). Key mental well-being themes appeared across all levels of the SEM, except the policy level. For the individual environment, one main theme was food as a coping mechanism and source of emotional distress. In the interpersonal environment, two themes were (a) blame and shame by family members and friends because of their weight and (b) condemnation and lack of support from health professionals. In the organizational environment, one main theme was inadequate support for mental well-being issues in obesity management programmes. In the community environment, one major theme the negative mental well-being impact of the social stigma of obesity. An overarching theme of weight stigma and bias further shaped the predominant themes in each level of the SEM. Addressing weight stigma and bias, and promoting positive mental well-being are two important areas of focus for supportive management of individuals living with obesity.

Ties That Bond: Youth Sport as a Vehicle for Social Identity and Positive Youth Development.

An emerging area of research has focused on understanding how the group dynamics of a sport team influence positive youth development (PYD). The identities that youth form through their membership in sport teams (i.e., social identities) have been found to influence teammate behavior and team performance. Yet, minimal work exists on social identity and PYD in youth sport. PURPOSE: The purpose of this study was to investigate the relationship between social identity and PYD in sport. METHOD: Youth engaged in recreational sport (N = 219; Mage = 11.61 years, SD = 1.39 years) completed measures of social identity and PYD in sport. The social identity measure assessed 3 dimensions including ingroup ties (IGT; perceptions of similarity, bonding, belongingness), cognitive centrality (importance of being a team member), and ingroup affect (IGA; feelings associated with group membership). A regression analysis was performed separately for 4 PYD outcomes (personal and social skills, goal setting, initiative, negative experiences) with the 3 dimensions of social identity entered as predictors. RESULTS: Regression analyses revealed that IGT and IGA were positively associated with personal and social skills (R2 Adj. = .29). Further, IGT predicted initiative (R2 Adj. = .16), whereas IGA was positively associated with goal setting (R2 Adj. = .17) and negatively associated with negative experiences (R2 Adj. = .08). CONCLUSION: The findings extend previous research highlighting the benefits of social identity on teammate behavior and team performance and demonstrate how social identity may contribute to PYD through sport.

Understanding gender norms, nutrition, and physical activity in adolescent girls: a scoping review.

Public health is currently focused on childhood obesity, and the associated behaviors of physical activity and nutrition. Canadian youth are insufficiently active and do not meet nutritional guidelines. This is of particular concern for adolescent girls, as they are less active than boys, become less active as they age, and engage in unhealthy weight control behaviors. The purpose of this review is to determine what is known from the existing literature about how gender norms are understood in relation to the health-related behaviors of PA and nutrition in young girls. This scoping review follows the framework of Arksey and O'Malley, involving defining a research question, study identification and selection, charting, interpretation, summarizing, and reporting. In total, 28 documents are reviewed, and characteristics are summarized quantitatively and qualitatively. Five major themes are identified: (1) Girls' relationships with PA are complex and require negotiating gender roles, (2) the literature focuses on dieting rather than nutrition, (3) appearance and perceptions influence behaviors, (4) "body" focused discourse is significant to girls' experiences, and (5) social influences, institutions, and environments are influential and may offer opportunity for future research and action. Gaps in the literature are identified and discussed. It is concluded that young girls' activity and nutrition is affected by gender norms and feminine ideals through complex negotiations, perceptions, body-centered discourse, and societal influences.

Privileging physical activity over healthy eating: 'Time' to Choose?

Physical activity and healthy eating have long been promoted as key strategies in tackling the 'wicked problem' of obesity. Both practices are assumed to go hand-in-hand, but whether one dominates the other has largely remained unexamined. Moreover, time, a dimension beyond the socio-ecological model, is a critical factor of families' busy lives, but related challenges are rarely articulated. We conducted 47 family interviews as part of a mixed methods study examining environmental influences on youth obesity in Nova Scotia, Eastern Canada. Participants were recruited from six schools at the junior high school level (grades 7-9; age range 12-14 years) based on location (urban, suburban and rural) and neighborhood socioeconomic status (high and low socioeconomic status). Time pressure to meet the demands associated with scheduled physical activity for youth was the dominant theme across interviews from all neighborhoods. Physical activity and healthy eating were valued differently, with greater value placed on physical activity than healthy eating. The pressure to engage youth in organized physical activity appeared to outweigh the importance of healthy eating, which led to neglecting family meals at home and consuming fast food and take out options. Our findings further reinforce the need to move beyond the socio-ecological model and integrate critical dimensions such as 'time', its challenges and opportunities, to allow for a more nuanced understanding of contemporary healthy living. It appears 'timely' to focus on healthy public policy in support of families, instead of unwittingly supporting a fast food industry that profits from time-pressured families.

Blame, Shame, and Lack of Support: A Multilevel Study on Obesity Management.

In this research, we examined the experiences of individuals living with obesity, the perceptions of health care providers, and the role of social, institutional, and political structures in the management of obesity. We used feminist poststructuralism as the guiding methodology because it questions everyday practices that many of us take for granted. We identified three key themes across the three participant groups: blame as a devastating relation of power, tensions in obesity management and prevention, and the prevailing medical management discourse. Our findings add to a growing body of literature that challenges a number of widely held assumptions about obesity within a health care system that is currently unsupportive of individuals living with obesity. Our identification of these three themes is an important finding in obesity management given the diversity of perspectives across the three groups and the tensions arising among them.

Dietary intake of Nova Scotia youth in grades 7 and 11.

PURPOSE: We examined dietary intakes among Nova Scotia youth, and analyzed whether these intakes met existing dietary guidelines. METHODS: Data from 1469 students in grades 7 and 11 from randomly selected schools were collected via a web-based dietary assessment tool, including a 24-hour recall. Nutrient analysis products were subjected to descriptive and inferential statistical analyses. RESULTS: Reported dietary intakes across sexes and grades showed the vast majority of youth did not meet minimum recommendations for fibre (96% to 98%) or vegetable and fruit servings (83.3% to 90.7%). Girls in grade 11 reported greater intakes of folate and lower intakes of saturated fat, and were less likely to report iron intakes at or above the Estimated Average Requirement than were grade 7 girls. Across ages, more than 75% of girls reported low calcium and folate intakes. Boys in both grades reported consuming more energy than did girls, and older boys reported consuming more than did younger boys. Foods outside the four main food groups contributed about 25% of total reported energy intake. Students in grade 7 consumed pop, salty snacks, and french fries more frequently than did students in grade 11. CONCLUSIONS: Adolescents' self-reported dietary intakes may not meet current dietary recommendations. Continued efforts are needed to develop innovative strategies to ensure healthy eating patterns.

Physical activity and nutrition among youth in rural, suburban and urban neighbourhood types.

OBJECTIVES: Physical activity and nutrition are essential to healthy living and particularly important during youth, when growth and development are key. This study examined rates of physical activity (PA) and diet quality (DQ) among youth in grades 7 to 9 in Halifax, Nova Scotia, during the 2008/09 school year and tested differences among students in rural, urban and suburban neighbourhood types of high and low socio-economic status (SES). METHODS: Youth in grades 7 through 9 (aged 12-16; 53% male) from six schools (N=380), stratified by neighbourhood type (urban, suburban, rural) and SES, wore accelerometers for up to 7 days (mean=4.14, standard deviation=1.49) and completed a nutritional survey. RESULTS: The findings suggest important differences in PA and DQ across SES and neighbourhood type. Specifically, rates of moderate to vigorous physical activity among youth from schools in lower socio-economic areas were higher in urban than in suburban or rural settings. Furthermore, DQ was better among youth in higher than in lower socio-economic urban settings. CONCLUSIONS: Understanding these differences in PA and DQ across rural, urban and suburban environments of high and low SES may highlight subgroups and targeted geographic areas for the design of interventions to improve rates of PA and health nutrition.

Physical activity of children and youth in Nova Scotia from 2001/02 and 2005/06.

OBJECTIVES: This paper reports on physical activity of students in grades 3, 7, and 11 from two surveillance studies (from 2001 and 2005). METHODS: Randomly selected students (Study1 n=1730; Study2 n=2341) from randomly selected schools in Nova Scotia participated. Physical activity was measured for seven consecutive days using Actigraph accelerometers. Descriptive statistics were calculated for moderate, hard, and very hard intensity, and total minutes of physical activity. Between study, grade, and sex differences were determined using univariate Analyses of Variance. RESULTS: Students in Study2 were significantly less active (mean [SD]=531.0 [392.3] min/week) than Study1 (662.2 [495.1] min/week). Girls were significantly less active (525.4 [419.1] min/week) than boys (657.1 [460.3] min/week). Students in grade 11 were significantly less active (225.2 [171.1] min/week) than students in grade 7 (457.5 [227.2] min/week) who were significantly less active than students in grade 3 (1038.4 [387.6] min/week). A significant study-grade interaction indicated that compared to students in grades 7 and 11, the level of physical activity in students in grade 3 was considerably lower in Study2 compared to Study1. CONCLUSIONS: Given the lower level of physical activity found in Study2, efforts at informing public policy and strategies that promote physical activity in children and youth should be made.

Are overweight students in Grades 3, 7, and 11 less physically active than their healthy weight counterparts?

OBJECTIVE: This study compared the accumulated minutes of objectively measured physical activity in 1,790 boys and girls in Grades 3, 7, and 11 classified as healthy weight, at risk of overweight, and overweight. METHODS: Height and weight were measured and body mass index calculated. Minutes of sedentary, light, moderate, hard, and very hard physical activity were obtained from a seven-day measurement of physical activity using an accelerometer (Actigraph, mode 7164; MTI). RESULTS: In Grade 3, boys (p=0.000) and girls (p=0.012) classified as overweight obtained significantly fewer minutes of very hard physical activity compared with their healthy weight counterparts. Boys in Grade 7 considered overweight obtained significantly fewer minutes of hard (p=0.002) and very hard physical activity (p=0.006) compared with boys who were a healthy weight. There were no significant differences in minutes of sedentary, light, moderate, hard, or very hard intensity physical activity in the boys and girls in Grade 11, who were considered a healthy weight, at risk of overweight, or overweight. CONCLUSIONS: Weak and inconsistent support was provided for the notion that boys and girls classified overweight are less physically active than their healthy weight counterparts.
