Existing research evidence indicates that children and adolescents of parents with a low socioeconomic position spend more time on sedentary behaviour than their counterparts. However, the mechanisms driving these differences remain poorly understood. The main aim of this systematic review was to summarize the evidence regarding the association between socioeconomic position and correlates of sedentary behaviour among youth (0-18 years) from developed countries. The literature search was conducted using MEDLINE, Embase, CINAHL and PsycINFO. A total of 37 studies were included. All but three studies examined screen-based sedentary behaviours only. Methodological quality ranged from low to moderate. Education was the most commonly used indicator of socioeconomic position, followed by income. Socioeconomic position was inversely related to the presence of a TV in the child's bedroom, parental modelling for TV viewing, parental co-viewing and eating meals in front of the TV. We found no/indeterminate evidence for an association between socioeconomic position and rules and regulations about screen time. The findings suggest possible factors that could be targeted in future intervention studies to decrease screen-based sedentary behaviour in lower socioeconomic groups in particular.
现有研究证据表明，社会经济地位较低的父母的子女和青少年比同龄人花在久坐行为上的时间更多。然而，导致这些差异的机制仍知之甚少。本系统综述的主要目的是总结关于发达国家青少年（0至18岁）社会经济地位与久坐行为相关因素之间关联的证据。使用MEDLINE、Embase、CINAHL和PsycINFO进行文献检索。共纳入37项研究。除三项研究外，所有研究仅考察了基于屏幕的久坐行为。方法学质量从低到中等不等。教育是社会经济地位最常用的指标，其次是收入。社会经济地位与儿童卧室中电视的拥有情况、父母看电视的示范行为、父母陪看以及在电视前用餐呈负相关。我们没有发现/不确定有证据表明社会经济地位与屏幕时间的规则和规定之间存在关联。研究结果表明了一些可能的因素，特别是在未来的干预研究中，可以针对这些因素来减少社会经济地位较低群体中基于屏幕的久坐行为。
