| 1 | Meeting 24-h movement guidelines: Prevalence, correlates, and the relationships with overweight and obesity among Chinese children and adolescents显示文摘Background:Meeting 24-h movement guidelines by children and adolescents has been associated with improved indicators of health,although it has been under-studied in China.Hence,this study aimed to investigate the prevalence of meeting the 24-h movement guidelines,its correlates,and its relationships with body mass index in children and adolescents in China.Methods:Cross-sectional data from the 2017 Youth Study in China of 114,072 children and adolescents(mean age=13.75 years,49.18%boys)were used.Meeting 24-h movement guidelines(60 min of daily moderate-to-vigorous physical activity,2 h of daily leisure screen time,911 h and 810 h nightly sleep duration for 613-year-olds and 1417-year-olds,respectively)and height and weight of all participants were assessed.The prevalence of meeting the 24-h movement guidelines and World Health Organization weight status categories were determined.Generalized linear models were used to determine the correlates of meeting the 24-h movement guidelines and the relationships of meeting the 24-h movement guidelines with overweight(OW)and obesity(OB).Results:Only 5.12%of Chinese children and adolescents met the 24-h movement guidelines,and 22.44%were classified as OW/OB.Older children and adolescents were less likely to meet the 24-h movement guidelines.Parental education level and family income were positively related to meeting the 24-h movement guidelines.Children and adolescents meeting the 24-h movement guidelines showed lower odds ratios for OW/OB.Compared with participants meeting the 24-h movement guidelines,boys in 4th6th grades met none of the recommendations(OR=1.22,95%CI:1.061.40),met the screen time recommendation only(OR=1.13,95%CI:1.011.28),met the nightly sleep duration recommendation only(OR=1.14,95%CI:1.031.28),and had significantly higher odds ratios for OW/OB.Similar trends were observed for girls in 4th6th grades:meeting none of the guidelines(OR=1.35,95%CI:1.141.59),meeting sleep duration guidelines only(OR=1.23,95%CI:1.081.39),and meeting moderate-to-vigorous physical activity+nightly sleep duration guidelines(OR=1.24,95%CI:1.011.54).For girls in 7th9th grades,the following trend was observed:meeting none of the guidelines(OR=1.30,95%CI:1.011.67).Conclusion:Very few Chinese children and adolescents met the 24-h movement guidelines.Age(negatively correlated),parental education level,and family income(both positively correlated)were correlates of meeting the 24-h movement guidelines.Children and adolescents meeting the 24-h movement guidelines were more likely to have lower risks for OW/OB,especially in the youngest age group(Grades 46);and girls in the middle age group(Grades 79)were also more likely to have lower risks for OW/OB.Further research studies should explore additional correlates and determinants for meeting the 24-h movement guidelines.Also,future studies should use longitudinal or interventional designs to determine the relationships between meeting the 24-h movement guidelines and OW/OB and other health indicators,while taking sex and age differences into account. | Si-Tong Chen Yang Liu Mark S.Tremblay Jin-Tao Hong Yan Tang Zhen-Bo Cao Jie Zhuang Zheng Zhu Xueping Wu Lijuan Wang Yujun Cai Peijie Chen | 2021 | Journal of Sport and Health Science2021，10，3： | 12 |
| 2 | 儿童青少年24 h活动行为与肥胖关联的系统评价显示文摘目的 针对基于成分数据分析的研究,系统评价身体活动(physical activity, PA)、久坐行为(sedentary behavior, SB)和睡眠与肥胖的关联或等时替代效应,为儿童青少年肥胖干预提供参考。方法 在中国知网、万方数据库、PubMed、SPORTDiscus、Web of Science和Medline数据库检索发表于2014年1月1日至2022年5月1日的相关研究。2名有经验的评价员独立完成文献的筛选、数据提取以及质量评估。结果 共纳入文献16篇,文献质量得分范围为7~12分。中高强度身体活动(moderate to vigorous physical activity, MVPA)、睡眠与肥胖均呈负相关,且MVPA替代其他行为可降低肥胖风险,替代时间为1.5~60 min/d。低强度身体活动(light physical activity, LPA)、SB与肥胖均呈正相关(P值均<0.05)。结论MVPA是儿童青少年肥胖干预的主要着眼点,在现有身体活动水平的基础上,每周增加60 min的MVPA可能是降低肥胖风险的最小量。 | 张婷 李红娟 张曌华 郜艳晖 | 2023 | 中国学校卫生2023，44，1： | 4 |
| 3 | Sedentary Behavior Research Network members support new Canadian 24-Hour Movement Guideline recommendations显示文摘A new paradigm employing 24-h movement guidelines that combines recommendations for movement behaviors across the whole day(physical activities of all intensities,sedentary behaviors,and sleep)is gaining momentum around the globe,and several jurisdictions are developing and releasing evidence-informed public health guidelines embracing this approach.1,2 The Sedentary Behavior Research Network(SBRN),the world’s largest network of researchers and health professionals focusing specifically on the health impact of sedentary behaviors,embraces this new paradigm and has worked to normalize the integration of sedentary behaviors into the movement-behavior paradigm. | Mark S.Tremblay Scott Rollo Travis J.Saunders | 2020 | Journal of Sport and Health Science2020，9，6： | 1 |
| 4 | 父母身体活动与青少年身体活动、身体质量指数的关系研究显示文摘使用韩国疾病管理中心的国家健康和营养调查(KNHANES,2019-2021年)数据分析父母身体活动对青少年身体活动、身体质量指数(BMI)的影响。结果表明:仅有10.1%的青少年达到身体活动标准,29.3%的青少年达到超重肥胖水平。其中父母身体活动与青少年身体活动具有相关性,而青少年身体活动与BMI具有相关性。通过使用Logistic回归,当父母身体活动都达标时,青少年身体活动提高22.429倍(95%CI:1.768~284.474)。只有父亲达标(OR=1.764,95%CI:0.949~3.329)、只有母亲达标(OR=2.229,95%CI:0.922~5.389)与青少年身体活动没有显著相关性。当父母身体活动达标时,会提高青少年BMI达标率,但没有显著相关性。研究结果认为:父母与青少年共同参与体育活动会对青少年子女的身体活动和BMI有积极影响。 | 郝嗣伟 赵国帅 王嘉伟 权黎明 | 2023 | 体育科技文献通报2023，31，11： | 0 |
| 5 | 《加拿大儿童早期24小时运动指南(0~4岁)》的内容、特点及启示显示文摘当前,学前儿童普遍身体活动不足,久坐行为较多,睡眠呈“晚睡晚起”模式,新冠疫情加剧了这种情况。身体活动不足、久坐行为以及不良睡眠习惯会导致学前儿童肥胖、问题行为等健康问题。睡眠、久坐行为和身体活动是分布在一天24小时内的3种行为,根据能量消耗,它们可以被统称为一种持续运动行为。 | 赵梦婕 黄翯青 何文义 | 2023 | 学前教育2023，，3： | 0 |
