Abstract
This paper systematically reviews and synthesizes the relevant literature on sedentary time research. A bibliometric analysis was conducted to evaluate the publications from 2010 to 2020 in the Web of Science (WoS) core collection database. Derwent Data Analyzer software was used for the cleaning, mining, and visualization of the data. Historical trends of the topics, main contributors, leading countries, leading institutions, leading research areas, and journals were explored. A total of 3020 publications were studied. The United States, the United Kingdom, and Australia are the three most productive countries. The Australian institution Baker Heart and Diabetes Institute led the list of productive institutions, and Ekelund U published the most papers. Sedentary time raised the concerns of scholars from 106 research areas, and public health was the dominant field. Physical activity, accelerometer, children, and obesity were the most frequently used keywords. The findings suggest that sedentary time is rapidly emerging as a global issue that has detrimental effects on public health. The hotspots shifted in the past 10 years, and COVID-19 was the most popular topic of sedentary time research.
Highlights
Sedentary time is rapidly emerging as a global issue that has detrimental effects on public health [1]
Accelerometer-based measurements or self-reported methods are widely used to assess the attribution of sedentary time and light or moderateto-vigorous physical activity, and samples are taken across all ages, genders, countries, and socioeconomic subgroups [29,30,31,32,33]
There are some other related keywords in sedentary time research, but in the pre-investigation, we found that the core literature is within the scope of “sedentary time” retrieval, whereas there are quite a few irrelevant documents in the retrieval results of “sedentary behavior”, “sitting time”, “screen time”, and “sedentary lifestyle”
Summary
Sedentary time is rapidly emerging as a global issue that has detrimental effects on public health [1]. Sedentary behavior is defined as any waking activity with very low (≤1.5 MET) energy expenditure [2]. It is typically characterized by time spent sitting or screening in various domains of life, including leisure [3,4], occupation [5,6], and transportation [7,8]. The effect of exercise on systolic time intervals in sedentary individuals and rehabilitated patients with heart disease was studied in 1971 [10]. Previous research has identified that sedentary behavior and physical activity are determined by or correlated with individual socioeconomic status, the environment, and related health policies [34,35,36]. It is well recognized that approaches to prevent such diseases and promote health benefits should seek to both increase regular physical activity and decrease sedentary behaviors [46]
