■不到四分之一的美国儿童符合体育锻炼（PA）指南。了解PA发生的背景以及这些背景如何在满足PA指南中发挥作用是制定有效行为干预措施的重要一步。这项研究的目的是检查PA环境(体育参与，参加其他有组织的体育活动，积极上学，和户外游戏）以及在居住在德克萨斯州的代表性儿童样本中，儿童符合PA指南的天数。
■我们分析了德克萨斯州四年级儿童的全州样本的横截面数据，这些儿童完成了2019-2020德克萨斯州学校体育活动和营养（TexasSPAN）调查。德州SPAN调查旨在监测全州范围内学龄儿童超重/肥胖的患病率，并评估习惯性自我报告的肥胖相关行为。包括饮食和PA。加权泊松回归模型被用来检验PA环境(体育参与，参加其他有组织的体育活动，积极上学，和户外游戏)以及儿童符合PA指南的天数，适应性，种族/民族,超重/肥胖，城乡地位，和经济劣势。
■在一周内每天都有16.7％的四年级儿童达到体育锻炼指南（平均年龄=9.4±0.6岁；女性=48.7，西班牙裔占51.8％，符合PA指南的平均天数=3.6±2.3天)。十分之一（11.2％）的儿童在一周中的任何一天都不符合每日PA指南，72.1%的人在1到6天之间遇到了他们。参加体育运动（b=0.22，95CI：0.14，0.30），任何其他有组织的体育活动(b=0.13,95CI:0.017,0.19)，在过去一周中，在户外玩耍1-3天（b=0.25，95CI：0.04，0.46）和4-7天（b=0.77，95CI：0.57，0.97）与儿童符合PA指南的天数显着正相关。
■参加体育运动，参加其他有组织的体育活动，在户外玩耍可能会对儿童符合PA指南的天数产生有益的影响。PA计划应考虑这些环境因素，并研究如何在儿童中有效，适当地促进有组织的活动和户外活动。
UNASSIGNED: Less than one-quarter of US children meet physical activity (PA)
guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA
guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas.
UNASSIGNED: We analyzed cross-sectional data from a statewide sample of fourth-grade children in Texas who completed the 2019-2020 Texas School Physical Activity and Nutrition (Texas SPAN) survey. The Texas SPAN survey was designed to monitor the statewide prevalence of overweight/obesity among school children and assess habitual self-reported obesity-related behaviors, including diet and PA. Weighted Poisson regression models were employed to examine the associations between PA contexts (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines, adjusting for sex, race/ethnicity, overweight/obesity, urban-rural status, and economic disadvantage.
UNASSIGNED: A total of 16.7% of fourth-grade children met physical activity
guidelines every day during the week (mean age = 9.4 ± 0.6 years; female = 48.7, 51.8% Hispanic, mean days meeting PA
guideline = 3.6 ± 2.3 days). One in ten (11.2%) children did not meet daily PA
guidelines on any day of the week, and 72.1% met them between 1 and 6 days. Participating in sports (b = 0.22, 95%CI:0.14, 0.30), any other organized physical activities (b=0.13, 95%CI:0.017, 0.19), and playing outdoors 1-3 days (b = 0.25, 95%CI:0.04, 0.46) and 4-7 days in the past week (b = 0.77, 95%CI:0.57, 0.97) was significantly and positively associated with the number of days children met PA guidelines.
UNASSIGNED: Participating in sports, participating in other organized physical activities, and playing outdoors may beneficially influence the number of days children meet PA guidelines. PA programs should consider these contextual factors and investigate how to promote organized activities and outdoor play effectively and appropriately among children.
