Project Summary The 2018 Physical Activity Guidelines Scientific Report, which summarized the most up-to-date evidence, suggested that, for youth the evidence for the effects of physical activity on obesity prevention is strong but the evidence for the effects of sedentary behavior remains limited. The report recognizes several important knowledge gaps, one of which is regarding the independent and interactive effects of physical activity and sedentary behavior on health outcomes. The abrupt difference in the physical activity guidelines across the transitional stage from youth to adulthood (e.g., daily one hour for youth vs. weekly 2.5 hours for adults) is also recognized as problematic. To address these gaps, we propose to conduct a pooled analysis to quantify the independent and interactive effects of physical activity and sedentary behavior on adiposity in early adulthood. The main hypotheses are (1) a healthier physical activity pattern during childhood and early adulthood is associated with lower adiposity in early adulthood, independent of sedentary behavior, and (2) a healthier sedentary behavior pattern is associated with lower adiposity in early adulthood only among those with a less healthy physical activity pattern. The first aim of this study is to examine the diverse trajectory patterns of moderate- and vigorous-intensity physical activity and sedentary behavior from age 11 to 24 years, using a group-based dual trajectory analysis approach. The second aim is to compare adiposity at age 22-24 years by moderate- and vigorous-intensity physical activity and sedentary behavior trajectory patterns. Two sub-aims are: to examine whether healthier physical activity and/or sedentary behavior patterns are associated with a lower risk of obesity at age 22-24 years among children with early childhood obesity; and to examine a dose- response relationship of moderate- and vigorous-intensity physical activity and sedentary behavior with fat mass change in the youth to adult transition period (from age 15-17 to 22-24 years). To achieve these aims, we will use pooled data from three birth cohort studies: U.K. Avon Longitudinal Study of Parents and Children, Brazil 1993 Pelotas Study, and U.S. Iowa Bone Development Study. The pooled data will enable us to have a diverse sample and sufficient power for the subgroup analysis. This low-cost self-contained R03 project is expected to produce new knowledge to update the Physical Activity Guidelines by addressing these knowledge gaps.

项目概要 2018年身体活动指南科学报告总结了最新证据， 表明，对于青少年来说，有充分的证据表明体力活动对预防肥胖有影响，但 关于久坐行为影响的证据仍然有限。报告指出了几个重要的 知识差距，其中之一是关于身体活动和身体活动的独立和相互作用的影响 久坐行为对健康结果的影响。各国身体活动指南的突然差异 从青少年到成年的过渡阶段（例如，青少年每天 1 小时，成人每周 2.5 小时） 被认为是有问题的。为了解决这些差距，我们建议进行汇总分析以量化 体力活动和久坐行为对成年早期肥胖的独立和交互影响。 主要假设是（1）儿童期和成年早期更健康的身体活动模式是 与成年早期较低的肥胖率相关，与久坐行为无关，并且（2）更健康 久坐行为模式仅与成年早期较低的肥胖水平相关。 健康的身体活动模式。本研究的第一个目的是检查不同的轨迹模式 11 至 24 岁的中等强度和剧烈强度的体力活动以及久坐行为，使用 基于群体的双轨迹分析方法。第二个目标是比较 22-24 岁的肥胖情况 中等和剧烈强度的体力活动和久坐行为轨迹模式。两个子目标 是：检查更健康的身体活动和/或久坐行为模式是否与 患有早期儿童肥胖症的儿童在 22-24 岁时肥胖的风险较低；并检查剂量- 中等强度和剧烈强度体力活动和久坐行为与脂肪的反应关系 青少年到成人过渡期（从15-17岁到22-24岁）的大规模变化。为了实现这些目标， 我们将使用来自三项出生队列研究的汇总数据：英国雅芳父母和儿童纵向研究， 巴西 1993 年 Pelotas 研究和美国爱荷华州骨骼发育研究。汇集的数据将使我们能够 样本多样，亚组分析能力充足。这个低成本的独立 R03 项目是 预计将产生新的知识，通过解决这些知识来更新身体活动指南 差距。
