Abstract：
UNASSIGNED: High levels of sedentary behavior in workplaces are currently recognized as an independent risk factor for cognitive dysfunction and poor mental health. However, sedentary patterns vary between workdays and non-workdays, which may influence cognitive functions.
UNASSIGNED: The present study aimed to quantify and compare work and nonwork device-measured sedentary time (ST) and its association with cognitive function in Indian office workers.
UNASSIGNED: In an ongoing randomized controlled trial (SMART-STEP), the baseline data of 136 full-time office workers, including accelerometer-measured sedentary patterns and cognitive functions, were analyzed. The ST was measured using a hip-worn accelerometer (Actigraph wGT3X-BT) for seven days, and executive functions were measured using computer-based tests. Linear regression models were employed to analyze the relationships between ST and executive function measures.
UNASSIGNED: The median daily ST of Indian office workers was 11.41 hours. The ST was greater on both workdays (11.43 hrs.) and non-workdays (11.14 hrs.) though different (F = 6.76, p = 0.001, ηp2 = 0.032). Office workers accumulate more prolonged sitting bouts (+21.36 min) during work days than non-workdays. No associations between device-measured ST and executive functions were observed.
UNASSIGNED: Indian office workers exhibited high ST patterns, especially on workdays. Although lower than workdays, Indian office workers exhibited more ST patterns during non-workdays than did their Western counterparts. Culturally adaptable workplace and leisure time physical activity interventions are needed to address the high ST of Indian office workers.

摘要：
■工作场所中久坐行为的高水平目前被认为是认知功能障碍和心理健康不良的独立危险因素。然而,久坐模式在工作日和非工作日之间有所不同，这可能会影响认知功能。
■本研究旨在量化和比较印度上班族的工作和非工作设备测量的久坐时间（ST）及其与认知功能的关联。
■在一项正在进行的随机对照试验（SMART-STEP）中，136名全职上班族的基线数据，包括加速度计测量的久坐模式和认知功能，进行了分析。使用髋部佩戴的加速度计（ActigraphwGT3X-BT）测量ST7天，和执行功能是使用基于计算机的测试来测量的。采用线性回归模型分析ST与执行功能测量之间的关系。
■印度上班族的每日ST中值为11.41小时。ST在两个工作日（11.43小时。)和非工作日(11.14小时。)虽然不同(F=6.76，p=0.001，ηp2=0.032)。办公室工作人员在工作日比非工作日积累更多的长时间坐着比赛（21.36分钟）。未观察到装置测量的ST和执行功能之间的关联。
■印度上班族表现出高ST型，尤其是在工作日。虽然低于工作日，印度上班族在非工作日表现出比西方同行更多的ST模式。需要文化适应性强的工作场所和休闲时间体育活动干预措施，以解决印度上班族的高ST问题。
