Objective In this study we aimed to examine the reliability and validity of the wristband activity monitor against the accelerometer for *** A total of 99 children(mean age = 13.0 ± 2.5 y) wore the two monitors in a free-living context for 7 days. Reliability was measured by intraclass correlation to evaluate consistency over ***-measures analyses of variance was used to detect differences across days. Spearman’s correlation coefficient(rho), median of absolute percentage error, and Bland-Altman analyses were performed to assess the validity of the wristband against the Acti Graph accelerometer. The optimal number of repeated measures for the wristband was calculated by using the Spearman-Brown prophecy *** The wristband had high reliability for all variables, although physical activity data were different across 7 days. A strong correlation for steps(rho: 0.72, P < 0.001), and moderate correlations for time spent on total physical activity(rho: 0.63, P < 0.001) and physical activity energy expenditure(rho: 0.57, P < 0.001) were observed between the wristband and the accelerometer. For different intensities of physical activity, weak to moderate correlations were found(rho: 0.38 to 0.55, P < 0.001).Conclusion The wristband activity monitor seems to be reliable and valid for measurement of overall children’s physical activity, providing a feasible objective method of physical activity surveillance in children.

The Provision of Active After-School Clubs for Children in English Primary Schools: Implications for Increasing Children’s Physical Activity

中国营养学会第十五届全国营养科学大会

This study was aimed at examining the trends and correlates of physical activity(PA) and sedentary behaviors among Chinese children. Methods A total of 4,341 subjects(6,936 observations) aged 6–17 years who participated in the China Health and Nutrition Survey(2004–2015) were included. Of the subjects, 41% participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors. Results From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6–17 years increased by 5.5%(odds ratio [OR], 1.51;95% confidence interval [CI], 1.19–1.90;P < 0.001). The PA volume declined by 5.8 metabolic equivalent of task-hr/week(P < 0.001), and the time spent in sedentary behaviors increased by 1.8 hr/week(P < 0.001). Age, ethnicity, and region showed significant effects on the PA volume across the quartiles(P < 0.001). Across the quartiles, sedentary time was significantly higher in the children residing in urban areas(P < 0.001) or areas with high urbanization levels(P ≤ 0.005) than in their counterparts. Conclusion A declining PA trend among Chinese children aged 6–17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.

Introduction: The transition from primary to secondary school is a period when physical activity (PA) declines. Interventions delivered during curriculum time have had limited impact on PA. The after-school period may offer a valuable opportunity to increase children’s PA. In order to identify how best to implement after-school PA interventions for older primary school children, more information regarding the provision of after-school clubs is required. This paper examined the current after-school club provision of English primary schools. Methods: All state-funded primary schools in England (n = 15,307) were sent an online questionnaire in two phases during 2013. Schools were asked about the active and non-active after-school clubs on offer to year 5 and year 6 pupils and the days on which they run, the number of children attending each after-school club, who funds the club and who leads the club. Results: Responding schools (501) were reasonably representative of the national profile. Of the 2413 clubs reported, more non-active than active clubs (5.3 vs. 4.8 per school) were described. Football was the most frequently reported activity (offered by 79.5% of schools), with netball and dance being offered by 45.3% and 44.1% of schools, respectively. A high proportion of clubs was funded by schools or parents (88.6%) and more than 40% were led by external parties. Conclusions: A number of PA programmes are provided after-school but current provision is dominated by team sports and thus, there is a need for non-sport specific PA clubs. Furthermore, there is a need to find cost-effective methods of delivering after-school PA programmes.

Many girls do not engage in sufficient physical activity (PA). Dance is a popular form of PA among UKsecondary school-aged girls and extracurricular dance programs delivered by dance specialists may provide an alternative way to increase PA amongst girls aged 11 - 12. The purpose of this study was to explore the views of physical education and dance teachers on the structure, content and delivery of an extra-curricular dance-based PA intervention for adolescent girls. Methods: Semi-structured qualitative interviews were conducted with eleven physical education teachers and eleven dance teachers, and were analyzed using thematic analysis. Results: Themes identified addressed key logistical and content/delivery-based factors to be considered when designing a dance-based PA intervention. Logistical factors included optimizing participant recruitment and aligning external providers with school behavior management policies. Content/delivery factors focused on teacher-student rapport, facilitating dance competence, and balancing teacher and student-led time. Conclusions: This formative study highlighted that an extra-curricular dance-based PA intervention would be welcomed inUK schools. A number of considerations central to the design and delivery of such a program were identified from key user groups which can be used to inform the development of school-based dance (and non-dance) interventions aimed at increasing PA amongst adolescent girls.

在海拔4000米的安第斯山中,艾马拉人在自己险恶但峻美的土地上,一如从前,崇敬自然。这里曾是一个庆祝生命的地方,它昌盛过,衰败过,今天又沐浴在重生的光明之中。作者来到玻利维亚偏远的高地,想探寻古代蒂亚瓦纳科人的直系后裔艾马拉人的秘密：信仰和仪式是如何给予他们力量与能力,让他们能在这片不毛之地上建起伟大神庙之城的,以及,对他们来说至关重要的啤酒又扮演着怎样的神圣角色。
