The objective was to systematically review the literature to determine whether sedentary time was associated with cardiometabolic diseases and their risk factors among South Asian adults.
Six electronic databases were searched to identify all studies that examined the association between sedentary time and cardiometabolic diseases (e.g., diabetes, cardiovascular disease) and their risk factors [e.g., body mass index (BMI), waist circumference (WC), lipids, blood pressure (BP), glucose] among South Asian adults. Two independent reviewers performed abstract/full-text screening, data abstraction, and quality assessments.
Searching identified 1757 potential articles; 22 were used in the analysis. Greater sedentary time was associated with an increased likelihood of diabetes (n = 5), higher BMI (n = 13), WC (n = 3), BP (n = 2), and glucose (n = 4). Thirteen out of 22 studies were of higher quality.
Results identified a trend whereby greater sedentary time was associated with an increased risk for diabetes, and several other cardiometabolic risk factors among South Asian adults. High quality studies are needed to identify whether risk factors are independent of physical activity levels to inform culturally-specific interventions for South Asians.
本研究旨在系统回顾文献，以确定久坐时间是否与南亚成年人的心血管代谢疾病及其风险因素相关。
检索了六个电子数据库，以识别所有研究南亚成年人久坐时间与心血管代谢疾病（如糖尿病、心血管疾病）及其风险因素[如体重指数（BMI）、腰围（WC）、血脂、血压（BP）、血糖]之间关联的研究。两名独立评审员进行摘要/全文筛选、数据提取和质量评估。
检索到1757篇潜在文章；22篇用于分析。久坐时间越长，患糖尿病的可能性越高（n = 5），BMI（n = 13）、WC（n = 3）、BP（n = 2）和血糖（n = 4）越高。22项研究中有13项质量较高。
结果发现一种趋势，即久坐时间越长，南亚成年人患糖尿病及其他几种心血管代谢风险因素的风险越高。需要高质量的研究来确定这些风险因素是否独立于身体活动水平，以便为针对南亚人的特定文化干预提供依据。
