Relationship Between Sedentary Behavior and Cardiovascular Risk.

The majority of adults do not meet current guideline recommendations for moderate to vigorous physical activity. Recent research has linked a high amount of sedentary behavior with an increased risk of obesity, diabetes, the metabolic syndrome, cardiovascular disease, and death. This correlation with sedentary behavior even extends to individuals who meet recommended physical activity goals during the remainder of their day, which implies that sedentary behavior may represent a distinct cardiovascular risk factor that is independent of the overall amount of physical activity. During the past several years, there has been significant interest in identifying and understanding the mechanisms through which sedentary behavior affects cardiovascular health. In this review, we critically evaluate the literature pertaining to sedentary behavior and cardiovascular risk with an emphasis on studies published over the past year, and we suggest possible interventions that may help reduce sedentary behavior time.
