Association between obesity and sedentary behavior in adults

Abstract

Although sedentary behavior (SB) is related to the development of metabolic diseases, there is still no consensus in literature about the association between accelerometer-based SB and obesity, especially adjusted for cardiovascular risk factors and level of daily physical activities. The aim was to evaluate the association between obesity and SB adjusted for potential confounders in adults. Data from 780 participants of the Epidemiology and Human Movement (EPIMOV) Study were analyzed. Body weight, body mass index (BMI), and fat body mass as percentage (%FBM) (bioelectrical impedance) were obtained and, then, used to stratify participants. SB was objectively measured using triaxial waist-worn accelerometers placed above the dominant hip during waking hours for at least four consecutive days (4-7 days). SB and its pattern were not significantly different between obesity groups. Although SB presented some significant correlations with obesity, the correlation and determination coefficient indicated weak association between SB and obesity (e.g., BMI and %FBM). Obesity presented little or no association with SB and its pattern after adjustment for potential confounders, especially when SB is measured through accelerometry.

Reallocating Time to Physical Activity and Sleep: Associations with Body Mass Index in Cancer Survivors

“…and the diminishing return of MVPA once PA guidelines are achieved [21,22]. Additionally, higher time is positively associated with BMI, even when controlling for MVPA [23], which may explain why reallocating sedentary time resulted in significant associations with BMI while reallocating MVPA time did not in this active sample of cancer survivors. Further, the current study also provides some evidence for a potential positive effect of reallocating sedentary time to light PA on BMI.…”
