Abstract：
UNASSIGNED: Sedentary behavior (SB) is detrimental to cardiometabolic disease (CMD) risk, which can begin in young adulthood. To devise effective SB-CMD interventions in young adults, it is important to understand which context-specific sedentary behaviors (CS-SB) are most detrimental for CMD risk, the lifestyle behaviors that co-exist with CS-SBs, and the socioecological predictors of CS-SB.
UNASSIGNED: This longitudinal observational study will recruit 500 college-aged (18-24 years) individuals. Two laboratory visits will occur, spaced 12 months apart, where a composite CMD risk score (e.g., arterial stiffness, metabolic and inflammatory biomarkers, heart rate variability, and body composition) will be calculated, and questionnaires to measure lifestyle behaviors and different levels of the socioecological model will be administered. After each visit, total SB (activPAL) and CS-SB (television, transportation, academic/ occupational, leisure computer, \"other\"; ecological momentary assessment) will be measured across seven days.
UNASSIGNED: It is hypothesized that certain CS-SB will show stronger associations with CMD risk, compared to T-SB, even after accounting for coexisting lifestyle behaviors. It is expected that a range of intra-individual, inter-individual, and physical environment socioecological factors will predict CS-SB. The findings from this study will support the development of an evidence-based, multi-level intervention to target SB reduction and mitigate CMD risk in CBYA.

摘要：
背景：久坐行为（SB）对心脏代谢疾病（CMD）风险有害，这可以从年轻的成年开始。为了在年轻人中设计有效的SB-CMD干预措施，重要的是要了解哪些特定环境的久坐行为（CS-SB）对CMD风险最有害，与CS-SB共存的生活方式行为，以及CS-SB的社会生态预测因子。方法这项纵向观察研究将招募500名大学生（18-24岁）。将进行两次实验室访问，相隔12个月，其中复合CMD风险评分(例如，动脉僵硬度,代谢和炎症生物标志物，心率变异性,和身体成分)将被计算，并进行问卷调查，以测量生活方式行为和社会生态模型的不同水平。每次访问后,总SB(activPAL)和CS-SB(电视，交通运输,学术/职业,休闲电脑,\“其他\”；生态瞬时评估)将在七天内进行测量。讨论假设某些CS-SB将显示与CMD风险的更强关联，与T-SB相比，即使考虑到共存的生活方式行为。预计一系列的个体内，个体间,物理环境和社会生态因素将预测CS-SB。这项研究的结果将支持基于证据的发展，多层次干预以降低SB为目标，减轻CBYA的CMD风险。
