Parent-youth associations of physical activity and the influence of family and neighbourhood social factors

Objectif: Examiner le lien entre la participation des parents aux activités physiques (AP) de leur enfant et les habitudes de vie et le statut pondéral de ces derniers. Méthode: Les données proviennent de l’Enquête Sociale et Santé des Enfants et des Adolescent Québécois (1999), comprenant des échantillons représentatifs de jeunes de 9, 13 et 16 ans (n=2511). L’implication des parents est définie par aucun, 1 seul, ou 2 parents faisant de l’AP avec leur enfant ≥1/semaine. Un rappel 7 jours a servi à classer les jeunes selon leur niveau d’AP, soit faible, modéré ou élevé. Le temps d’écran a été défini par: ≤14 vs. >14 heures/semaine. Le statut pondéral a été défini selon les critères de Cole. Résultats: Lorsque les deux parents participent aux AP du jeune, le niveau d’AP des adolescents de 13 (OR 3.89, IC 95%: 1.85-8.18) et 16 ans (OR 3.45, IC 95%: 1.32-9.01) est davantage élevé, et le temps d’écran moindre (OR 2.36, IC 95%: 1.30-4.25) chez ceux de 13 ans. Des analyses secondaires montrent que le lien entre l’implication des parents et le niveau d’AP des jeunes est présent chez les familles biparentales seulement; le lien avec le temps d’écran est présent dans les quartiers sécuritaires seulement. Aucune association n’est observée pour le statut pondéral. Conclusion: Les stratégies de promotion de la santé ciblant la participation des parents aux AP de leurs enfants pourraient réduire le fardeau des maladies chroniques, étant donné l’association favorable entre leur implication et les habitudes de vie des jeunes.

Participation in leisure and physical activity among children and adolescents with juvenile idiopathic arthritis

Contexte: L’arthrite juvénile idiopathique (AJI) est l’une des maladies chroniques auto-immune les plus répandues chez les enfants et est caractérisée par des enflures articulaires (maladie active), de la douleur, de la fatigue et des raideurs matinales pouvant restreindre leur niveau de participation aux activités quotidiennes (par exemple: les loisirs, l’activité physique, la mobilité et les soins personnels) à la maison comme à l’école. Participer aux activités de loisirs et à l’activité physique a des bienfaits au niveau de la santé et du développement de tous les enfants et démontrent aussi des effets positifs qui réduisent les symptômes des maladies chroniques telle l’AJI. Malgré ces bienfaits la participation aux loisirs chez les jeunes avec l’AJI demeure largement sous-étudiée. Objectifs: Cette étude vise à évaluer le niveau de participation aux loisirs et à l’activité physique chez les enfants et les adolescents atteints d’AJI, ainsi qu’à identifier les facteurs liés à la maladie, la personne et l’environnement. Méthodes : L’évaluation du niveau de participation et l’exploration des facteurs associés aux loisirs et à l’activité physique ont été complétés par l’entremise d’une revue systématique de la littérature, l’analyse de données d’un échantillon national représentatif d’enfants canadiens atteints d’arthrite âgés entre 5 et 14 ans (npondéré = 4350), ainsi que l’analyse standardisée du niveau de participation aux loisirs à l’aide du Children’s Assessment of Participation and Enjoyment (n=107) et la mesure objective de l’activité physique par accéléromètre (n=76) auprès d’un échantillon d’enfants (âgés entre 8 et 11 ans ) et d’adolescents (âgés entre 12 et 17 ans) suivis en clinique de rhumatologie à l’hôpital de Montréal pour enfants, Centre Universitaire de Santé McGill. Les résultats cliniques ont été comparés à des données normatives, ainsi qu’à un groupe contrôle sans AJI. Nous avons exploré les facteurs associés avec le niveau de participation aux loisirs et à l’activité physique en utilisant les modèles de régression linéaire multiple et l’analyse hiérarchique. Résultats : Les enfants et les adolescents atteints d’AJI participent à une multitude d’activités de loisirs; cependant ils sont moins souvent impliqués dans des activités physiques et de raffinement en comparaison aux autres types d’activités de loisirs. Ceux avec l’AJI étaient en général moins actifs que leurs pairs sans arthrite et la plupart n’atteignaient pas les recommandations nationales d’activité physique. Les garçons avec l’AJI participent plus souvent à des activités physiques et moins aux activités sociales, de raffinement et de développement de soi en comparaison avec les filles ayant l’AJI. En général, être un garçon, être plus âgé, avoir une meilleure motivation pour participer aux activités de motricité globale, avoir un statut socio-économique plus élevé et être d’origine culturelle canadienne sont associés à un niveau de participation plus élevé aux activités physiques. La préférence pour les activités de raffinement, un niveau d’éducation maternelle plus élevé et être une fille étaient associés à un niveau de participation plus élevé aux activités de raffinement. Conclusion: La participation aux loisirs et à l’activité physique en AJI est un concept complexe et semble surtout être expliqué par des facteurs personnels et environnementaux. L’identification des facteurs associés aux loisirs et à l’activité physique est très importante en AJI puisqu’elle peut permettre aux professionnels de la santé de développer des interventions significatives basées sur les activités préférées des enfants, améliorer l’observance au traitement et promouvoir des habitudes de vie saine.

Pedometer: intervention strategy and physical activity promotion

World Health Organization (WHO) has prioritized physical activity (PA) as one of the mostrelevant strategies leading the decreasing prevalence of noncommunicable chronic diseases. Pedometer has emerged as one of the valid intervention programs, reliable and useful to assess,measure and promote the physical activity practice, through counts the number of steps perday. One of the aims is to establish the goals based on steps per day made by a person and thepositive feedback, which can generate behavior changes and adoption of healthy habits, from a regular physical activity practice perspective. This review attends to enhance the current state ofpedometer program, as an intervention one, in all kind of population; its health impact and theapplication methodologies, using the pedometer as a steps quantifier device, with feasible access,use and management. Additionally, the review will be useful as a framework to design futureresearch projects, aim to develop, adapt and apply evidence based pedometer protocols, insideclinical, academic and community context.

Reflections about physiotherapist professional performance in the field of physical activity

The physiotherapist professional activities, in the beginning were focused only in the clinical field, nowadays it has many different action fields including Physical Activity. Physical activity can be viewed from two dimensions: one biological, which is defined as any activity which requires energy expenditure involving the combined action of multiple systems; on the other side social, understood as a human activity concerning subjectivity conditions influenced by the environment where the individual and the community are developed. Given these dimensions as well as national and international benchmarks this paper’s objective is to present a series of reflections that the authors have done regarding the physiotherapist professional performance in the field of physical activity and the large possibilities derived from their practice in this field.

Parental and peer support on physical activity among portuguese children and adolescents

Objetivo: A presente dissertação de mestrado teve como principal objetivo estudar a associação entre o suporte parental e dos pares na atividade física das crianças e adolescentes dos 10 aos 17 anos de idade. Método: Foi efetuada uma revisão sistemática de literatura (RSL) onde se sumarizou o estado da arte sobre a temática. Posteriormente foi realizado um estudo observacional transversal onde se investigou como o suporte dos pais (tangível e intangível) e dos pares estão associados com a atividade física entre crianças e adolescentes, examinando as diferenças entre géneros e a sua variação com a idade. Participaram no estudo 1876 crianças e adolescentes, de ambos os sexos, entre os 10 aos 17 anos de idade, participantes do projeto PESSOA. Resultados: Os resultados do estudo transversal corroboram os resultados de alguns estudos da revisão sistemática de literatura uma vez que, apesar das diferenças metodológicas entre os estudos, foram encontradas correlações significativas entre o suporte parental e o nível de atividade física das crianças e adolescentes. Há diferenças entre géneros no tipo de suporte parental e no suporte dos pares. O estudo transversal demonstrou uma associação positiva entre o suporte dos pares e a idade. Esta associação destaca-se na transição da infância para a adolescência. Em ambos os géneros, o suporte dos pares registou uma maior associação à atividade física do que o suporte dos pais. Conclusões: A realização deste estudo demonstra que os pais e os pares são fatores chave na atividade física das crianças e adolescentes. Em diferentes fases da infância e da adolescência, o papel de cada um deles altera-se de acordo com vários fatores do envolvimento físico e social. É necessário mais investigação nesta área, preferencialmente estudos longitudinais que permitam uma melhor compreensão de como as diferentes fontes (pais e pares) e os diferentes tipos de suporte (tangível e intangível) evoluem ao longo da infância e da adolescência e qual o seu impacto nos diferentes níveis de atividade física.

Lack of association between PCK1 polymorphisms and obesity, physical activity, and fitness in European Youth Heart Study (EYHS)

Phosphoenolpyruvate carboxykinase-1 (PCK1) is the rate-limiting enzyme in the hepatic gluconeogenic pathway. Studies have shown that overexpression of Pck1 in mice results in obesity-related traits and higher levels of physical activity (PA). Therefore, our aims were to investigate whether common genetic variation in the PCK1 gene influences obesity-related traits, PA, and fitness, and to examine whether PA and fitness attenuate the influence of the PCK1 polymorphisms on obesity in children. Analyses were undertaken on data from Danish and Estonian children (958 boys and 1,104 girls) from the European Youth Heart Study (EYHS), a school-based, cross-sectional study of children (mean ± s.d. age: 9.6 ± 0.4 years) and adolescents (15.5 ± 0.5 years). We genotyped eight polymorphisms that captured the common genetic variations in the PCK1 gene. The association between the PCK1 polymorphisms and BMI, waist circumference (WC), sum of four skinfolds, PA, and fitness was tested using an additive model adjusted for age, age-group, gender, maturity, and country. Interactions were tested by including interaction terms in the model. None of the polymorphisms were significantly associated with BMI, WC, sum of four skinfolds, PA, and fitness, and also with the risk of being overweight or obese (P > 0.05). The interactions between the polymorphisms and age-group, gender, PA, and fitness were not statistically significant. This is the first study to comprehensively examine the association of PCK1 polymorphisms with obesity, PA, and fitness. Despite strong evidence from animal studies, our study in the EYHS cohort failed to identify an association of PCK1 polymorphisms with obesity, PA, and fitness.

Bizzy Break! The effect of a classroom-based activity break on in-school physical activity levels of primary school children

The school has been identified as a key setting to promote physical activity. The purpose of this study was to evaluate the effect of a classroom-based activity break on in-school step counts of primary school children. Data for 90 children (49 boys, 41 girls, 9.3 ± 1.4 years) from three Irish primary schools is presented. In each school one class was randomly assigned as the intervention group and another as controls. Children's step counts were measured for five consecutive days during school hours at baseline and follow-up. Teachers of the intervention classes led a 10 min activity break in the classroom each day (Bizzy Break!). Mean daily in-school steps for the intervention at baseline and follow-up were 5351 and 5054. Corresponding values for the control group were 5469 and 4246. There was a significant difference in the change in daily steps from baseline to follow-up between groups (p < .05). There was no evidence that girls and boys responded differently to the intervention (p > .05). Children participating in a daily 10 min classroom-based activity break undertake more physical activity during school hours than controls.

‘I like playing on my trampoline; it makes me feel alive’ valuing physical activity: perceptions and meanings for children and implications for primary schools

This study investigated perceptions that children aged 6–10 years (n = 83) have of what it means to be physically active. Ideographic research was conducted utilising drawings and interviews to understand values that are placed on participating in physical activity (PA). The article questions the idea that whilst it may be commonly accepted by academics that there is a need to be active for health, little research has considered what this may actually mean for the child. Drawing on Bourdieu, the article utilises key concepts within the analysis of ‘capital' to frame an understanding of how children experience PA. Findings suggest that central to children's experiences is the place of social interaction and reciprocation. The article investigated the production and transference of forms of capital: physical, cultural and social. The potential for such concepts to be exploited by schools is discussed with reference to physical education and opportunities offered during free play.

Behavioral economics, wearable devices, and cooperative games: results from a population-based intervention to increase physical activity

Background: Health care literature supports the development of accessible interventions that integrate behavioral economics, wearable devices, principles of evidence-based behavior change, and community support. However, there are limited real-world examples of large scale, population-based, member-driven reward platforms. Subsequently, a paucity of outcome data exists and health economic effects remain largely theoretical. To complicate matters, an emerging area of research is defining the role of Superusers, the small percentage of unusually engaged digital health participants who may influence other members. Objective: The objective of this preliminary study is to analyze descriptive data from GOODcoins, a self-guided, free-to-consumer engagement and rewards platform incentivizing walking, running and cycling. Registered members accessed the GOODcoins platform through PCs, tablets or mobile devices, and had the opportunity to sync wearables to track activity. Following registration, members were encouraged to join gamified group challenges and compare their progress with that of others. As members met challenge targets, they were rewarded with GOODcoins, which could be redeemed for planet- or people-friendly products. Methods: Outcome data were obtained from the GOODcoins custom SQL database. The reporting period was December 1, 2014 to May 1, 2015. Descriptive self-report data were analyzed using MySQL and MS Excel. Results: The study period includes data from 1298 users who were connected to an exercise tracking device. Females consisted of 52.6% (n=683) of the study population, 33.7% (n=438) were between the ages of 20-29, and 24.8% (n=322) were between the ages of 30-39. 77.5% (n=1006) of connected and active members met daily-recommended physical activity guidelines of 30 minutes, with a total daily average activity of 107 minutes (95% CI 90, 124). Of all connected and active users, 96.1% (n=1248) listed walking as their primary activity. For members who exchanged GOODcoins, the mean balance was 4,000 (95% CI 3850, 4150) at time of redemption, and 50.4% (n=61) of exchanges were for fitness or outdoor products, while 4.1% (n=5) were for food-related items. Participants were most likely to complete challenges when rewards were between 201-300 GOODcoins. Conclusions: The purpose of this study is to form a baseline for future research. Overall, results indicate that challenges and incentives may be effective for connected and active members, and may play a role in achieving daily-recommended activity guidelines. Registrants were typically younger, walking was the primary activity, and rewards were mainly exchanged for fitness or outdoor products. Remaining to be determined is whether members were already physically active at time of registration and are representative of healthy adherers, or were previously inactive and were incentivized to change their behavior. As challenges are gamified, there is an opportunity to investigate the role of superusers and healthy adherers, impacts on behavioral norms, and how cooperative games and incentives can be leveraged across stratified populations. Study limitations and future research agendas are discussed.

Objectively measured physical activity in European adults: cross-sectional findings from the Food4Me study

Background Comparisons of objectively measured physical activity (PA) between residents of European countries measured concurrently with the same protocol are lacking. We aimed to compare PA between the seven European countries involved in the Food4Me Study, using accelerometer data collected remotely via the Internet. Methods Of the 1607 participants recruited, 1287 (539 men and 748 women) provided at least 3 weekdays and 2 weekend days of valid accelerometer data (TracmorD) at baseline and were included in the present analyses. Results Men were significantly more active than women (physical activity level = 1.74 vs. 1.70, p < 0.001). Time spent in light PA and moderate PA differed significantly between countries but only for women. Adherence to the World Health Organization recommendation to accumulate at least 150 min of moderate-equivalent PA weekly was similar between countries for men (range: 54–65%) but differed significantly between countries for women (range: 26–49%). Prevalence estimates decreased substantially for men and women in all seven countries when PA guidelines were defined as achieving 30 min of moderate and vigorous PA per day. Conclusions We were able to obtain valid accelerometer data in real time via the Internet from 80% of participants. Although our estimates are higher compared with data from Sweden, Norway, Portugal and the US, there is room for improvement in PA for all countries involved in the Food4Me Study.

Investigating Environmental Determinants of Diet, Physical Activity, and Overweight among Adults in Sao Paulo, Brazil

There is worldwide recognition that the burden of noncommunicable diseases (NCDs) and obesity-related health problems is rapidly increasing in low- and middle-income countries. Environmental determinants of obesity are likely to differ between countries, particularly in those undergoing rapid socioeconomic and nutrition transitions such as Brazil. This study aims to describe some built environment and local food environment variables and to explore their association with the overweight rate and diet and physical activity area-level aggregated indicators of adults living in the city of Sao Paulo, the largest city in Brazil. This formative study includes an ecological analysis of environmental factors associated with overweight across 31 submunicipalities of the city of Sao Paulo using statistical and spatial analyses. Average prevalence of overweight was 41.69% (95% confidence interval 38.74, 44.64), ranging from 27.14% to 60.75% across the submunicipalities. There was a wide geographical variation of both individual diet and physical activity, and indicators of food and built environments, favoring wealthier areas. After controlling for area socioeconomic status, there was a positive correlation between regular fruits and vegetables (FV) intake and density of FV specialized food markets (r = 0.497; p < 0.001), but no relationship between fast-food restaurant density and overweight prevalence was found. A negative association between overweight prevalence and density of parks and public sport facilities was seen (r = -0.527; p < 0.05). Understanding the relationship between local neighborhood environments and increasing rates of poor diet, physical activity, and obesity is essential in countries undergoing rapid economic and urban development, such as Brazil, in order to provide insights for policies to reduce increasing rates of NCDs and food access and health inequalities.
