Objective: to investigate, through a systematic review, the effects of sedentary behavior on the metabolic syndrome and its components in adults. Methodology: This is a systematic review, using the Trip Database databases through the following descriptors: adults; sedentary behavior or screen time or sedentary life style; cardiometabolic risk or cardiovascular risk or metabolic risk score, published between 2013 and 2018. Results: Some cross-sectional studies show a greater chance of developing metabolic syndrome when sedentary time is increased. However, most sedentary time intervention studies with mild physical activity or posture change do not have a significant effect on cardiometabolic mark ers. Conclusion: According to the results of the selected studies, there is an association between high sedentary time and the development of metabolic syndrome and its components in adults Keywords— Adult, Sedentary Behavior, Metabolic Syndrome. I. INTRODUCTION The current model of society and technological advances can negatively affect the population's way of life, causing the human being to have to work less physically to perform his or her daily life tasks. For this reason, sitting time (watching television, motorized, using the computer, playing video games, hanging around chatting with friends, talking on the phone among other similar activities) who require little energy expenditure, has become increasingly prevalent society current (CHURCH et al., 2011). In this context, the definition of sedentary behavior was defined as a series of states in which the individual remains awake with energy expenditure <1.5 METs (Metabolic Equivalent Term), excluding sleep time (TREMBLA Y et al., 2017). Farias Júnior (2011) describes in his study that the term sedentary behavior is different from the sedentary one within the level of physical activity, since it has specific "categorical" as well as pathological consequences in the health of the individuals. Sedentary behavior is not characterized simply as an absence of physical activities or the attendance of specific scores in its classification (BIDDLE et al., 2009). Sedentary behavior has been associated with several deleterious health factors such as obesity, type 2 diabetes, cardiovascular diseases and all-cause mortality (YOUNG et al., 2016). Among these factors, the metabolic syndrome has also received differentiated attention, since it is considered as a group of factors, which allies increase the chance of developing type 2 diabetes and cardiovascular disease (HUANG, 2009).
