Active commuting to and/or from school (ACS) is an opportunity to increase daily physical activity (PA) levels in young people. Mobile-device interventions focused on promoting the practice of health-related PA can be more cost-effective than traditional interventions in this population. Objective: To analyze the adolescents’ opinion of the mobile application (app) Mystic School, which was designed to promote ACS in Spanish adolescents. Methods: A total of 44 students (14–15 years old) from Granada and Jaén participated in the test of the Mystic School app during two phases: phase 1 (n = 10) for 2 weeks and phase 2 (n = 34) for 1 month. Each phase included an app presentation, a follow-up, and focus group sessions. The qualitative analysis was carried out through NVivo software. Results: In phase 1, adolescents reported improvements in the design and functioning, such as the avatar movement, virtual steps utilities, and multiplayer function. These suggestions were included in phase 2. After phase 2, adolescents reported that it is important to add the possibility of playing without an Internet connection to the game, to include more competitive options, prizes, and to increase the difficulty of the levels. In both phases, problems with the step number counting remained. Conclusion: The Mystic School app can be a useful tool for the physical education teacher to integrate the content from this curriculum related to the promotion of PA, such as ACS., Spanish Government, European Commission, University of Granada Plan Propio de Investigacion 2016-Excellence actions: Unit of Excellence on Exercise and Health (UCEES) DEP2016-75598-R, Junta de Andalucia, Consejeria de Conocimiento, Investigacion y Universidades, European Commission SOMM17/6107/UGR

(1) To analyze the effectiveness of a school-based sleep education program on sleep duration, latency, and efficiency, as well as separated by weekdays and weekend days and by sex. (2) To analyze children's sleep patterns (duration, latency, and efficiency) on weekdays and weekend days and by sex. A total of 110 children (average age of 8.4 (0.3) years, 62% girls) (experimental group (60 children, girls 52%) and control group (50 children, girls 74%) from 5 schools in Granada (Spain) participated in the study. The sleep patterns were measured by accelerometers attached to the non-dominant wrist 7 days/24 h, and by sleep log. The program lasted 8 weeks with a total of eight activities (one activity per week). Regarding our first objective, sleep duration decreased significantly in both groups on weekdays (p = 0.004) and weekend days (p

The low rates of active commuting to/from school in Spain, especially by bike, and the wide range of cycling interventions in the literature show that this is a necessary research subject. The aims of this study were: (1) to assess the feasibility of a school-based cycling intervention program for adolescents, (2) to analyse the effectiveness of a school-based cycling intervention program on the rates of cycling and other forms of active commuting to/from school (ACS), and perceived barriers to active commuting in adolescents. A total of 122 adolescents from Granada, Jaén and Valencia (Spain) participated in the study. The cycling intervention group participated in a school-based intervention program to promote cycling to school during Physical Education (PE) sessions in order to analyse the changes in the dependent variables at baseline and follow up of the intervention. Wilcoxon, Signs and McNemar tests were undertaken. The association of the intervention program with commuting behaviour, and perceived barriers to commuting, were analysed by binary logistic regression. There were improvements in knowledge at follow-up and the cycling skill scores were medium-low. The rates of cycling to school and active commuting to/from school did not change, and only the “built environment (walk)” barrier increased in the cycling group at follow-up. School-based interventions may be feasibly effective tools to increase ACS behaviour, but it is necessary to implement a longer period and continue testing further school-based cycling interventions., Spanish Government, European Commission DEP2016-75598-R, University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES), Junta de Andalucia, European Regional Development Fund (ERDF), "R&D research staff contract, within the framework of the Spanish National Youth Guarantee" - Junta de Andalucia, European Social Fund (ESF), Spanish Government FPU18/04251 FPU17/03934

Es fundamental elaborar un protocolo de evaluación para garantizar rigor y homogeneidad en cualquier estudio de investigación. Asimismo, se requieren consideraciones específicas si la investigación se desarrolla en contexto educativo y en diferentes centros educativos. Este trabajo tiene como objetivo describir el protocolo de evaluación del estudio de investigación titulado: Estudio PACO “Pedalea y Anda al Colegio”. Además, se aportan recomendaciones globales y aplicaciones prácticas en el contexto educativo. El principal objetivo del estudio PACO es fomentar el comportamiento de desplazamiento activo entre estudiantes de Educación Secundaria Obligatoria para mejorar los niveles de actividad física y otros indicadores de salud asociados. Por ello, el protocolo de evaluación incluye la metodología e instrumentos específicos para evaluar en los adolescentes variables como: 1) modo de desplazamiento al centro educativo y otros factores psicosociales asociados a dicho desplazamiento mediante el cuestionario PACO alumnos, 2) barreras familiares para el desplazamiento activo al centro educativo mediante el cuestionario PACO familias, 3) características antropométricas (peso, talla, perímetro de cintura y de cuello), 4) niveles de actividad física y gasto energético evaluados mediante acelererometría y 5) características de la ruta real casa-colegio registradas mediante Sistema de Posicionamiento Global. La transparencia en la metodología y logística necesaria para evaluar dichas variables en contexto educativo, es la clave para garantizar el rigor y la homogeneidad en futuras implementaciones, ya sean estas realizadas por investigadores o docentes. Finalmente, los datos obtenidos, serán fiables y relevantes para implementar estrategias educativas que fomenten la salud integral de los adolescentes. Abstract. It is essential to develop an evaluation protocol to develop rigor and homogeneity in any research study. Likewise, some considerations are specifically needed if the research is carried out in an educational context and in different schools. This work aims to describe y the evaluation protocol of the research study entitled: PACO Study “Cycle and Walk to School”. In addition, it provides global recommendations and practical applications in the educational context. The main objective of the PACO Study is to promote the behaviour of active commuting among students of Compulsory Secondary Education to improve their physical activity levels and other associated health indicators. For this reason, the evaluation protocol includes the specific methodology and instruments for evaluating variables such as: 1) mode of commuting to school and other psychosocial factors associated with active commuting through the PACO student questionnaire, 2) family barriers to active commuting to school through the PACO families questionnaire, 3) anthropometric characteristics (weight, height, waist and neck circumference), 4) levels of physical activity and energy expenditure evaluated by accelerometry and 5) characteristics of the real home-school route through a Global Positioning System. The transparency in the methodology and logistic necessary to evaluate the variables in the educational context is key to evaluate the rigor and homogeneity in future implementations, whether they are carried out by researchers or teachers. Finally, the obtained data will be reliable and relevant to implement educational strategies in order to promote an integral health of the adolescents.

Objective:The goals of this study were to (1) describe physical activity levels during school recess in 8-year-old children, (2) analyse the percentage of children who achieved physical activity recommendation at recess, and (3) examine if recess physical activity levels varied by gender, weight status, and parental educational level.Methods:In all, 291 children (mean age ± SD = 8.3 ± 0.3 years, 156 boys) from 7 schools of Granada (Spain) were recruited by convenience. To analyse sedentary time and physical activity levels during recess, children wore a tri-axial accelerometer attached to the wrist over five consecutive school days.Results:Sedentary time (29.6% vs 40%) and light physical activity (33.2% vs 35.5%) were lower in boys than in girls (all p Conclusions:Levels of moderate-vigorous physical activity during school recess are very low in children, being lower in girls than in boys, a very low percentage of children achieve moderate-vigorous physical activity recommendations during school recess, and girls and overweight/obese children show lower values in moderate-vigorous and vigorous physical activity.

The aims of the present study were to analyse the gender differences in balance, catching, aiming and change of direction ability (CODA) in elementary education students and to determine th...

Introduction Parental barriers are a key factor to determine physical activity behaviors, such as active commuting to school in young people. The purpose of this study was to test the reliability and validity of a questionnaire which addresses parental barriers towards active commuting to school. Methods This paper describes the development, following the Delphi method, and the validation of a Likert-scale questionnaire of 23 items (Parental Perception of Barriers towards Active Commuting to School (PABACS)) designed to determine the main parental barriers. These barriers are categorized into 3 scales (general, walking, and cycling barriers) and the overall questionnaire. A total of 207 parents of children and adolescents in Granada (Spain) in 2016 completed the survey on two occasions. The internal consistency was examined using Cronbach's alpha tests and Intra-Class Correlation (ICC) and Kappa index were used to assess the reliability of the different questions. To examine the predictive validity, spearman's rho tests were conducted. Results The questionnaire showed a good internal consistency for the overall questionnaire and for the three scales. The Intra-Class Correlation values were moderate. The overall questionnaire and the general and walking barriers scales showed a moderate validity to predict active modes of commuting, as well as the items ‘distance’ and ‘walking convenience’. Conclusions This study provides a reliable tool to assess parental barriers towards active commuting to school, which will help future studies to identify the most important barriers on which institutions have to focus to increase active commuting to school rates.

Active commuting to school (ACS) provides children and adolescents an opportunity to increase their physical activity levels. Perceived parental barriers are important factors that can influence in...

Aim: The aims of this study were (1) to examine the associations between self-reported health-related quality of life (HRQoL), health-related physical fitness (cardiorespiratory fitness, muscular strength, and speed-agility), and mode of commuting to and from school in Spanish children, and separately by gender and (2) to analyse the difference in cardiorespiratory fitness by mode of commuting to and from school by gender. Methods: We conducted a cross-sectional analysis that included 415 children aged 8.47 ± 0.36 years from 14 schools in Granada, Spain. The HRQoL outcome was assessed using the valid and reliable KINDL-R questionnaire, which covers six life dimensions, children’s physical fitness was assessed using the ALPHA fitness test battery, and while commuting to and from school was assessed using the valid, reliable, and feasible ‘Mode and Frequency of Commuting To and From School Questionnaire’. Results: Cardiorespiratory fitness was positively correlated with all dimensions of HRQoL in boys, whereas higher muscular strength (standing long jump) was positively correlated with the emotional wellbeing dimension in girls. In addition, boys who actively commute to school (walking) presented better cardiorespiratory fitness. Moreover, children who actively commuted to school (walking) presented better scores for the emotional wellbeing, family, and school dimensions, as well as total scores (both, p Conclusion: In our study, HRQoL was positively correlated with cardiorespiratory fitness in boys (all dimensions), whereas muscular strength (standing long jump) was positively correlated with the emotional wellbeing dimension only in girls. Active commuting to and from school was associated with higher levels of cardiorespiratory fitness, school dimension, and KINDL-R total score. Improving cardiorespiratory fitness might be especially useful to improve HRQoL in children, and vice versa.

Introduction: Physical education (PE) can contribute to total daily physical activity (PA) among children. In consequence, the Spanish Ministry of Education, Culture and Sport has developed 16 teaching units focused on increasing PA levels during PE lessons, called Unidades Didacticas Activas (UDA; Active Teaching Units). Objectives: The goal of this study was to compare whether children participating in UDA lessons spent more time in moderate-to-vigorous physical activity (MVPA) than children participating in traditional lessons. Design: Quasi-experimental design. Methods: A total of 355 children (8-9 years old, 53.9% boys) from 7 schools in Granada participated in the study. Students were divided into two groups: a traditional PE group (n = 204) and a UDA group (n = 151). Time spent in MVPA was assessed using tri-axial accelerometers. Results: Time spent in MVPA was higher in the group engaged in the UDA lessons compared to the group that received traditional lessons (13.6 vs 15.2 minutes, p = .021, Standard Error = 0.27). The percentage of children who met international MVPA recommendations was similar for both groups (UDAs: 12.7% and traditional: 13.2%, p = .504). Conclusions: UDA lessons and their methodology favoured greater participation in MVPA compared to a traditional PE approach. It will be important to change PE methodology (including duration, frequency and focus) to achieve MVPA goals., The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the Spanish Ministry of Economy and Competitiveness [DEP2015-63988-R] and FJHD was supported by a grant from the Spanish Ministry of Education, Culture and Sport [CAST17/00072].

The authors thank the study participants and collaborators on the individual studies that provided data for this pooled IPD analysis., Objectives To determine if subpopulations of students benefit equally from school-based physical activity interventions in terms of cardiorespiratory fitness and physical activity. To examine if physical activity intensity mediates improvements in cardiorespiratory fitness. Design Pooled analysis of individual participant data from controlled trials that assessed the impact of school-based physical activity interventions on cardiorespiratory fitness and device-measured physical activity. Participants Data for 6621 children and adolescents aged 4-18 years from 20 trials were included. Main outcome measures Peak oxygen consumption (VO2Peak mL/kg/min) and minutes of moderate and vigorous physical activity. Results Interventions modestly improved students’ cardiorespiratory fitness by 0.47 mL/kg/min (95% confidence interval 0.33 to 0.61), but the effects were not distributed equally across subpopulations. Girls and older students benefited less than boys and younger students, respectively. Students with lower levels of initial fitness, and those with higher levels of baseline physical activity benefitted more than those who were initially fitter and less active, respectively. Interventions had a modest positive effect on physical activity with approximately one additional minute per day of both moderate and vigorous physical activity. Changes in vigorous, but not moderate intensity, physical activity explained a small amount (~5%) of the intervention effect on cardiorespiratory fitness. Conclusions Future interventions should include targeted strategies to address the needs of girls and older students. Interventions may also be improved by promoting more vigorous intensity physical activity. Interventions could mitigate declining youth cardiorespiratory fitness, increase physical activity, and promote cardiovascular health if they can be delivered equitably and their effects sustained at the population level.

La evaluacion de la condicion fisica tradicionalmente ha estado vinculada al paradigma de rendimiento, que ha orientado la calificacion hacia la eficacia del estudiante. El presente estudio tiene como objeto analizar la capacidad cardiorrespiratoria en adolescentes de Cadiz (Espana). Ademas, este trabajo aporta una calculadora de rendimiento y esfuerzo para guiar la evaluacion formativa de la capacidad cardiorrespiratoria y aportar orientaciones metodologicas para su aplicacion en el ambito escolar. Participaron 323 estudiantes de entre 12 y 19 anos (Medad=14.68; ±1.75), 168 chicos (52%) y 155 chicas (48%). Se valoro la capacidad cardiorrespiratoria a traves del test de 20 metros de ida y vuelta al que se le incorporo pistas de audio. Los participantes fueron monitorizados con un pulsometro (ONrhythm 500) y respondieron a una escala de percepcion de esfuerzo (Borg, escala 1-10). Los valores medios para las variables analizadas fueron: ultimo estadio completado, 5.92 (±2.47); frecuencia cardiaca (FC) maxima, 198.02 (±0.71); diferencia entre la FC maxima teorica y real, -0.33 (±11.05); percepcion de esfuerzo, 7.87 (±2.03). A partir de los resultados obtenidos se elaboro una calculadora para estimar el esfuerzo y orientar el analisis del rendimiento. Se espera que sea una herramienta util para los profesores de Educacion Fisica e investigadores para calcular el nivel de condicion cardiorrespiratoria, estimar el esfuerzo y analizar el nivel de riesgo de padecer una enfermedad cardiovascular.===Physical fitness assessment has traditionally been linked to a performance paradigm, which has oriented the grades towards student effectiveness. The present study aims to analyze the cardiorespiratory capacity in adolescents from Cadiz (Spain). In addition this work provides a performance and effort tool to guide formative and shared assessment of cardiorespiratory fitness and to provide methodological guidance for its application in the school setting. Students. A total of 323 students between 12 and 19 years (mean age 14.68; ±1.75), 168 boys (52%) and 155 girls (48%). Cardiorespiratory capacity was assessed by an adaptation of the original 20-meter shuttle run test, which consisted on including music. Participants were monitored with a heart rate monitor (ONrhythm 500) and registered the Borg rating of perceived exertion scale (1-10). Mean values for the variables analyzed were: last completed stage, 5.92 (±2.47); maximum heart rate, 198.02 (±0.71); difference between theoretical and real maximum HR, -0.33 (±11.05); perception of effort, 7.87 (±2.03). Based on the results obtained, a calculator was developed to estimate effort and provide guidance in performance analysis. It is elaborated to be a useful tool for Physical Education teachers and researchers to assess cardiorespiratory fitness, estimate the effort and to analyze the risk of future cardiovascular disease.

The purpose was to examine the feasibility of the 20m shuttle run test with music and to test its concurrent validity with the original 20m shuttle run test. A total of 386 adolescents (14.5±1.6 years old, 48.9% boys) participated in our study. A self-reported questionnaire was used to assess student's perception about the 20m shuttle run test with music and the original and to assess perceived exertion. Participants performed randomly the 20m shuttle run test with music and original two weeks apart. Average and maximum heart rate were monitored with heart rate monitors. The 20m shuttle run with music was a feasible test for measuring cardiorespiratory fitness in adolescents. The concurrent validity showed mean differences of 5.1±14.6 for shuttles, 0.3±0.8 km/h for speed, 0.5±4.1 for stages, and 1.5±4.1 for VO2max (all p0.001) in favour of the 20m shuttle run with music vs. the original 20m shuttle run test. Mean difference for the rating of perceived exertion was 0.4±2.5 points (p=0.003). No significant difference was found between boys and girls. In conclusion, the 20mSRT-music is feasible and presents a good concurrent validity in adolescents, independently of the sex and it will be an alternative and good approach to assess cardiorespiratory fitness.

Background Active commuting to school (ACS) is an important source to increase the total daily physical activity in youth and improve their health. How the ACS rates change along the time is of interest. The objective of this study was to examine trends in the rates of ACS in a large sample of Spanish children and adolescents aged 6–18 years from 2010 to 2017. The study period included the economic crisis in Spain (2008 to 2013) and secondary analysis was conducted to compare ACS rates during and after the economic crisis. Methods To investigate trends in ACS among Spanish children and adolescents, data were obtained from 28 studies conducted across Spain. The study sample comprised 18,343 children (6 to 11.9 years old; 50.5% girls) and 18,438 adolescents (12 to 18 years old; 49.5% girls). The overall trends in ACS were evaluated using multilevel logistic regression analysis. Results The rates of ACS in Spanish children and adolescents did not change significantly during the 2010–2017 period, except a sporadic increase in the rate of ACS in adolescents in 2012–2013. No significant association between the ACS and the economic crisis time period in either children or adolescents were found. These findings are in contrast to recently reported declines in ACS rates in other countries. Conclusions Strong partnerships between researchers, public health practitioners, policy-makers and communities, as well as long-term commitment and evaluations of interventions aiming to increase ACS are necessary to ensure positive results in the long term.

User engagement in digital (serious) games may be important to increase their effectiveness. Insights into how to create engaging games for healthy lifestyle promotion are needed, as despite their potential, not all digital (serious) games are highly engaging. This study systematically reviewed game features that were associated with higher user engagement among youth. A systematic search was conducted in PubMed, Web of Science, CINAHL, and PsycARTICLES databases. Qualitative and quantitative studies were included, if they documented game features associated with youth engagement. Coding of game features was performed using the mechanics-dynamics-aesthetics (MDA) framework. A total of 60 studies met the inclusion criteria and were included in the registered systematic review (No. CRD42018099487). Results showed that various game features were associated with user engagement in digital (serious) games: an attractive storyline, adaptable to gender and age, including diverse (antagonist) characters the user may identify with, high-end realistic graphics, well-defined instructions, which can be skipped, in combination with clear feedback and a balance of educational and fun content. This review underpinned the relevance of investigating engaging game features specifically for youth, as deviations were found with characteristics that are engaging for other populations.

We are grateful to Ana Yara Postigo Fuentes for her assistance with the English language. Also, we would like to express our gratitude to the children, parents, teachers and schools for allowing us to carry out this school program, as well as for their involvement and support during the process., The relationship between physical activity (PA), cardiorespiratory fitness (CRF) and academic achievement in young people is unclear. The aim of this study was to analyze the relationship between PA, CRF and academic achievement in 152 children according to sex (average age of 8.6 ± 0.3 years) in southern Spain. A tri-axial accelerometer was used to measure PA; the 20-m Shuttle Run Test was performed to assess the CRF; and to know the academic achievement, the official school records were considered. The results showed a weak correlation between moderate PA and moderate-to-vigorous PA (MVPA) with CRF in boys (all, 0.2 > r < 0.4; p < 0.05), whereas the vigorous PA showed a moderate and weak correlation with CRF (all, p < 0.05), in both boys (r = 0.537) and girls (r = 0.382), respectively. In addition, a weak inverse correlation between moderate PA and MVPA with academic achievement showed in girls (all, 0.2 > r < 0.4; p < 0.05). Finally, the CRF weakly correlated with academic achievement only in boys (all, 0.2 > r < 0.4; p < 0.05). Our study showed a relationship between PA and CRF in both sexes. Nonetheless, the PA was inversely related to academic achievement in girls, whereas the CRF was related to academic achievement in boys., This research was funded by the Spanish Ministry of Economy and Competitiveness [DEP2015-63988-R].

Objectives We aimed to systematically review parental barriers towards children and adolescents' active transport to school (ATS) in the scientific literature and to provide a categorization of the barriers identified in the studies. Methods A search was conducted through seven online databases, from the beginning of the database to March 2018. Results A total of 27 of the identified studies met the inclusion criteria. The main parental barriers reported by parents of children (21 studies) were built environment, traffic safety, distance, crime-related safety and social support. The main parental barriers reported by parents of adolescents (6 studies) were built environment (street connectivity), distance, traffic safety and physical and motivation barriers. The parental barriers associated with ATS were mainly related to the built environment and traffic safety. Conclusions It is crucial to involve parents through interventions to reduce the perception of safety and to increase awareness of the importance of ATS. In addition, these strategies should be complemented by environmental changes performed by local governments.

The main purposes of this study were to describe teacher education students’ values and degree of satisfaction with life, to analyze whether any differences by educational program, gender or living standard and to analyze the association between values and satisfaction with life. A total of 565 students of teacher degree programs (girls 415 (73.5%)) answered a self-administered questionnaire composed by two validates scales about their values (Portrait Values Questionnaire (PVQ) and satisfaction with life (Satisfaction with Life Scale)). The results showed that the most important values were self-direction, benevolence and hedonism, while the least important values were power, tradition and achievements. Females reported higher importance for benevolence, universalism, self-direction, stimulation, hedonism and security. Males reported higher importance for power. Students who live with family reported also more high values for power. Concerning satisfaction with life, it was associated to higher values of power. Current intervention programs have focused different approaches by gender and living standard. Programs focus on increasing satisfaction with life should consider the values structure of students., Los objetivos principales de este estudio fueron describir los valores y grado de satisfacción con la vida de los estudiantes del Grado de Maestro para analizar posibles diferencias entre programas, género o configuración familiar; y la correlación entre valores y satisfacción con la vida. Un total de 565 estudiantes de los Grados de Educación (415 chicas (73.5%)) contestaron un cuestionario auto-administrado compuesto por dos escalas validadas sobre valores (Portrait Values Questionnaire (PVQ) y satisfacción con la vida (Satisfaction With Life Scale)). Los resultados mostraron que los valores más importantes fueron autodirección, benevolencia y hedonismo, mientras que los menos importantes fueron, poder, tradición y logros. Las alumnas destacaron la benevolencia, el universalismo, la autodirección, estimulación, hedonismo y seguridad. Los varones destacaron el poder. Los estudiantes que viven con familiares también concedieron más relevancia al poder. La satisfacción con la vida está asociada al poder. Los programas actuales de intervención se han centrado en aproximaciones diferentes según género y configuración familiar. Los programas centrados en la satisfacción con la vida deberían considerar los valores del estudiantado., This study was supported by a grant from the Spanish Ministry of Education, Culture and Sport [CAST17/00072]

Physical activity (PA) and sleep contribute to better children&rsquo, s health. Nonetheless, the bidirectional relationship between both of these health-related factors is unclear when using objective measures. The aims of this study were (1) to describe the PA (light PA and moderate-to-vigorous PA (MVPA) and sleep (duration, latency, and efficiency) patterns of children and compare them with recommendations, and (2) to analyze the bidirectional association between PA levels and sleep patterns in 470 Spanish children according to sex (average age of 8.4 (0.4) years, 51.9% boys). A tri-axial accelerometer and sleep logs were used to measure PA (light PA and MVPA) and sleep patterns (duration, latency, and efficiency) in the children for seven consecutive days. Linear mixed models were conducted to analyze the bidirectional association (PA &rArr, sleep and sleep &rArr, PA) adjusted for the child, the sex, the school, and the day of observation. The results showed that, overall, the children did not meet the sleep duration recommendations per day. Regarding the bidirectional association, increased light PA and MVPA during the day was related to decreased sleep duration but an improvement in sleep efficiency that night. However, sleep duration and sleep efficiency were only related negatively and positively to light PA the following day, respectively. Regarding sex, light PA was associated with decreased sleep duration in both sexes, although the average value was lower in boys. In addition, light PA was also related only to an improvement in sleep efficiency the same night in both sexes, with girls generally having more efficient sleep. More studies in a representative sample of children that use objective measures to corroborate these results are needed.

Aim Physical activity has numerous benefits for children when it comes to academic achievements. This study determined whether active commuting – walking or cycling – to school, as a way of increasing total physical activity levels, was associated with academic achievements in students aged seven to 18 years. Methods A total of 2138 students participated in the study, which took place in the 2012/2013 academic year in three Spanish cities. We used a self-reported questionnaire to assess how the students travelled to and from school and their final school grades. Results We enrolled 489 primary schoolchildren and 1649 secondary schoolchildren, with similar numbers of boys and girls. The primary schoolchildren who travelled to school by motorbike, car or bus had better grades for all the selected school subjects (p ≤ 0.009) than those who walked or cycled. No significant associations were found for secondary schoolchildren, except for mathematics and their grade point averages. All models were adjusted for sex, age and school. Conclusion Active commuting to school was inversely associated with academic achievement in primary school students but not those at secondary school. Longitudinal and intervention studies are needed to further understand our findings.

Background Cardiovascular diseases are the leading cause of death in most countries of Latin America and physical inactivity is an important risk factor. Daily behaviors such as active commuting to school can provide a significant source of physical activity for children to improve the cardiovascular health. Parental perceptions of the environment such as distance to school or neighborhood safety are important to determine active commuting to school. The aim of this study was two-fold: to determine parental barriers to active commuting to school in Ecuadorian children and adolescents and to examine the association between the parental barriers and mode of commuting to school. Methods Parents of children (n=172, aged 9-12) and parents of adolescents (n=209, aged 13-18) completed a self-reported questionnaire about perceived parental barriers to active commuting to school. Differences of the parental perceived barriers between parents of children and parents of adolescents were analyzed using Chi-square test for every single barrier and Student T-test for independent samples to analyze the number of parental perceived barriers. The association between children's mode of commuting and parental barriers for each group of parents was examined using logistic regression analysis. Results The most common barriers reported by Ecuadorian parents of children were traffic volume (51.7%), traffic speed (50.0%) and crime (50.0%), whereas the most common barriers reported by Ecuadorian parents of adolescents were traffic speed (44.5%), distance to school (44.0%) and crime (44.0%). Parents of children reported absence of adults to walk with as the most important barrier compared to parents of adolescents (36.6% and 21.5% respectively, p=0.001). Parents of children who perceived as barriers distance to school (OR: 11.022; p Conclusions The most frequent perceived barriers for Ecuadorian parents were traffic volume, traffic speed, crime and distance, whereas barriers for parents of children were higher than parents of adolescents. Parents of children were more concern about presence of adults to walk with than parents of adolescents. It is important to improve the parental perceptions of distance and safety in dangerous intersections to promote active commuting to school in Ecuador.

The independent mobility (IM), defined as the freedom of young people to travel without adult supervision, has been related to the physical activity time, the acquisition of personal autonomy, to less intense fear of crime, and to a stronger feeling of being part of their community and other health and social benefits. The aims of this study were to compare parents' and adolescents' traffic- and crime-related safety perceptions of their neighborhood and to analyze the associations of these perceptions with adolescents' IM. A total of 291 adolescents and their parents completed the Neighborhood Environment Walkability Scale (NEWS) questionnaire. Multilevel (two-level models: individual levelÐneighborhood level) regression analyses were conducted to examine whether the environmental perceptions differed between parents and adolescents and the association between the parental and adolescents' perception to the IM and the active independent mobility (AIM). Parents reported a more negative perception of traffic (except for amount and speed) and crime-related safety. Adolescents' environmental perceptions were not associated with their IM but parental perceptions of traffic- and crime-related safety were associated with IM and with active IM, although not all associations were in the expected direction. Future urban policy efforts should address environments where parents perceive sufficient levels of safety to increase the levels of IM in adolescents., This study was supported by a grant from the Spanish Ministry of Education, Culture and Sport [CAST17/00072] and by a grant from the Research Foundation Flanders (FWO) [FWO12/ PDO/158].

PURPOSE: Active commuting has been associated to longer sleep duration in adolescents, however, the literature is still limited. Thus, the aim of this study was to investigate the association between the mode of commuting to and from school and sleep duration in Ecuadorian youth.METHODS: A total of

Background : Understanding parental barriers is crucial to promote active commuting to school since the parental perceptions influence how young people commute. This study examined parental barriers to active commuting to school among Spanish children and adolescents, and their association with their gender and the usual mode of commuting. Parents of children ( n = 628) and parents of adolescents ( n = 151) from Granada (Spain) completed a paper-based questionnaire about perceived parental barriers to active commuting to school and mode of commuting. Data were analyzed using the Chi-square test. Among Spanish parents, the most common barriers reported by parents of children were traffic volume and dangerous intersections, whereas the most frequent barriers reported by parents of adolescents were distance to school and dangerous intersections. Compared to parents of children, a greater proportion of parents of adolescents reported distance to school and crime and smaller proportion reported traffic volume as barriers to active commuting to school. Among parents of children, crime was a more commonly reported as a barrier by parents of girls. Although some barriers reported by parents of passive commuters were similar for children and adolescents (such as distance to school and absence of a policeman at crosswalks), other barriers were specific to parents of children. The main parental barriers to active commuting in children were traffic volume and dangerous intersections whereas for adolescents were distance and dangerous intersections. Among Spanish parents, parental barriers to active commuting are influenced by children's age, gender and mode of commuting to school.
