Opportunities for young people to be sedentary have increased during leisure time, study time, and transportation time.
This review paper focuses on sedentary behaviors among young people aged 2-18 years and includes evidence of the relationship between sedentary behavior and health risk indicators, an overview of public health recommendations, the prevalence of key sedentary behaviors, evidence of correlates of sedentary behavior and the effectiveness of interventions to reduce sedentary behaviors.
Although this is a narrative style review and not systematic, where possible, findings from relevant review papers were summarized and a search of more recent literature was performed using computer-based databases such as PubMed, Google Scholar, ERIC, PsycINFO, Social Science Index, SportDiscus, and Health Reference Center - Academic.
Young people spend 2-4 hours per day in screen-based behaviors and 5-10 hours per day sedentary. Ethnicity, sociodemographic status, having a TV set in the bedroom, and parental behavior appear to be the most consistent correlates of TV viewing time; however, few recent studies aiming to reduce TV viewing or sedentary time among young people have been successful.
A growing body of evidence supports the development of public health recommendations to limit the time spent in screen-based behaviors. More research is needed to examine the prospective and experimental evidence of associations between overall sedentary time and health, determinants of sedentary behaviors other than screen-based behaviors, and interventions to reduce overall sedentary time or even alternative sedentary behaviors, such as transport- or education-related sitting time.
在闲暇时间、学习时间和交通时间，年轻人久坐的机会增加了。
这篇综述文章主要关注 2-18 岁年轻人的久坐行为，包括久坐行为与健康风险指标之间关系的证据、公共卫生建议概述、主要久坐行为的流行率、久坐行为的相关因素的证据以及减少久坐行为的干预措施的有效性。
尽管这是一篇叙述性的综述，而非系统性综述，但在可能的情况下，对相关综述文章的发现进行了总结，并使用计算机数据库（如 PubMed、Google Scholar、ERIC、PsycINFO、Social Science Index、SportDiscus 和 Health Reference Center - Academic）对最新文献进行了搜索。
年轻人每天花 2-4 小时在屏幕行为上，5-10 小时处于久坐状态。种族、社会人口地位、卧室里有电视机以及父母的行为似乎是与看电视时间最相关的因素；然而，很少有旨在减少年轻人看电视或久坐时间的最新研究取得成功。
越来越多的证据支持制定公共卫生建议，以限制花在屏幕行为上的时间。需要更多的研究来检查总体久坐时间与健康之间的前瞻性和实验性关联、除屏幕行为外的久坐行为决定因素，以及减少总体久坐时间甚至替代久坐行为（如与交通或教育相关的坐姿时间）的干预措施。
