Physical inactivity is one of the most important risk factors contributing to morbidity and mortality in the world, although sedentary behavior (SB), low-intensity physical activity (LIPA), and shorter sleep duration have also been associated with various chronic diseases and physiopathological conditions that may affect health, irrespective of one's level of physical activity (PA). Current methods to evaluate and classify the PA level in the population appear to be limited, as they primarily focus on time spent performing moderate-to-vigorous PA (MVPA). The aim of this article is to analyze the scientific literature in regard to various combinations of patterns among sleep, SB, LIPA, and MVPA, in order to propose a more integrative PA classification in apparently healthy children, adolescents, and adults. In general, the most common classification is composed of four categories that combine MVPA with SB level as follows: i) "physically active" or "physically inactive" (meets or does not meet weekly MVPA recommendations) and ii) "high SB" or "low SB" (depending on amount of accumulated sedentary time per day).There is a consensus regarding the classification of physically active or not, but agreement has not been reached on the classification of a high SB or low SB level. This new, integrative approach appears to be an appropriate methodological proposal for categorizing the level of PA, with the aim of providing health professionals and researchers a more comprehensive vision of PA behaviors among the population.
缺乏身体活动是导致全球发病率和死亡率的最重要风险因素之一，尽管久坐行为（SB）、低强度身体活动（LIPA）以及较短的睡眠时间也与各种可能影响健康的慢性疾病和生理病理状况相关，而不论一个人的身体活动（PA）水平如何。目前评估和分类人群PA水平的方法似乎有限，因为它们主要关注进行中度至剧烈身体活动（MVPA）所花费的时间。本文的目的是分析关于睡眠、SB、LIPA和MVPA之间各种模式组合的科学文献，以便为看似健康的儿童、青少年和成年人提出一种更综合的PA分类。一般来说，最常见的分类由四类组成，将MVPA与SB水平结合如下：i）“身体活跃”或“身体不活跃”（达到或未达到每周MVPA建议）以及ii）“高SB”或“低SB”（取决于每天累积的久坐时间量）。关于身体是否活跃的分类存在共识，但对于高SB或低SB水平的分类尚未达成一致。这种新的综合方法似乎是一种对PA水平进行分类的合适方法建议，旨在为健康专业人员和研究人员提供人群中PA行为的更全面视角。
