在一天24小时的时间里，每一段给定的时间要么是久坐不动的行为，要么是睡眠，要么是轻度体力活动(LPA)，要么是中等到剧烈的体力活动(MVPA)。在流行病学研究中，大多数研究传统上是相互孤立地分析这些行为之间的联系；也就是说，没有考虑在剩余行为中花费的时间的转移。近年来，人们越来越有兴趣探索能量消耗范围内的所有行为是如何影响健康结果的。用于研究这些关联的统计模型被称为等时替代模型(ISM)。考虑到在所有年龄段进行的基于ISM的研究的数量不断增加，本论文旨在：(I)回顾和总结将ISM应用于睡眠、久坐行为和体力活动研究的结果；(Ii)评估研究的方法学质量；以及(Iii)建议该领域的未来研究方向。对10个数据库进行了系统搜索。采用纽卡斯尔-渥太华量表评价纳入研究的方法学质量。56项研究符合纳入标准，均具有中等或高度的方法学质量。据报道，在所有研究中，交流时间从1分钟到120分钟/天不等，其中30分钟/天是最常见的重新分配的时间量。总共使用了三种不同的ISM方法。最常被研究的与等时替代相关的健康结果是死亡率、一般健康、精神健康、肥胖、健康和心脏代谢生物标记物。似乎将久坐时间重新分配给LPA或MVPA与显著降低死亡风险有关。目前的证据似乎一直表明，当久坐不动的时间被更高强度的体力活动取代时，死亡风险的降低更大。对于肥胖症，似乎将久坐时间重新分配给体力活动可能与所有年龄段的体重指数、体脂百分比和腰围的减少有关，而体力活动强度越高，相关性越大。虽然有相对大量的证据表明，在成年人中，从久坐行为到LPA或MVPA的时间重新分配与心脏代谢生物标记物之间存在有益的关联，但在儿童、青少年和老年人中缺乏研究。虽然一些研究调查了一般健康、心理健康和健身结果，但对这些主题的进一步调查是有必要的。总体而言，当时间从久坐行为重新分配到MVPA时，似乎与健康结果的相关性最强。大多数研究都没有考虑睡眠时间，这是目前证据的一个主要限制。目前的证据表明，睡眠、久坐行为、LPA和MVPA之间的时间重新分配可能与许多健康结果有关。未来的研究应该采用纵向设计，考虑所有的运动行为，并检查更广泛的健康、心理、社会、经济和环境结果。本文的在线版本(10.1186/s12966-0180691-3)包含补充材料，可供授权用户使用。
During a 24-h day, each given period is spent in either sedentary behaviour, sleeping, light physical activity (LPA), or moderate-to-vigorous physical activity (MVPA). In epidemiological research most studies have traditionally analysed the associations of these behaviours in isolation from each other; that is, without taking into account the displacement of time spent in the remaining behaviours. In recent years, there has been a growing interest in exploring how all the behaviours across the energy expenditure spectrum influence health outcomes. A statistical model used to investigate these associations is termed an isotemporal substitution model (ISM). Considering the increasing number of ISM-based studies conducted in all age groups, the present paper aimed to: (i) review and summarise findings from studies that employed ISM in sleep, sedentary behaviour, and physical activity research; (ii) appraise the methodological quality of the studies; and (iii) suggest future research directions in this area. A systematic search of ten databases was performed. The Newcastle–Ottawa scale was used to assess the methodological quality of the included studies. Fifty-six studies met the inclusion criteria, all being of moderate or high methodological quality. Associations were reported for exchanged time varying from one minute to 120 min/day across the studies, with 30 min/day being the most common amount of time reallocated. In total, three different ISM methodologies were used. The most commonly studied health outcomes in relation to isotemporal substitutions were mortality, general health, mental health, adiposity, fitness, and cardiometabolic biomarkers. It seems that reallocations of sedentary time to LPA or MVPA are associated with significant reduction in mortality risk. Current evidence appears to consistently suggest that reductions in mortality risk are greater when time spent sedentary is replaced with higher intensities of physical activity. For adiposity, it seems that reallocating sedentary time to physical activity may be associated with reduced body mass index, body fat percentage, and waist circumference in all age groups, with the magnitude of associations being greater for higher intensities of physical activity. While there is a relatively large body of evidence reporting beneficial associations between the reallocation of time from sedentary behaviour to LPA or MVPA and cardiometabolic biomarkers among adults, there is a lack of studies among children, adolescents, and older adults. Although some studies investigated general health, mental health, and fitness outcomes, further investigation of these topics is warranted. In general, it seems that the strongest association with health outcomes is observed when time is reallocated from sedentary behaviour to MVPA. Most studies did not account for sleep time, which is a major limitation of the current evidence. The current evidence indicates that time reallocation between sleep, sedentary behaviour, LPA, and MVPA may be associated with a number of health outcomes. Future studies should employ longitudinal designs, take into account all movement behaviours, and examine a wider range of health, psychological, social, economic, and environmental outcomes.
