Purpose: This study aims to establish evidence-based accelerometer data reduction criteria to accurately assess sedentary patterns in children. We not only examined total sedentary time, but also duration and number of breaks and uninterrupted sedentary bouts. Methods: Participants (n=1057 European children; aged 10-12 yrs) wore an ActiGraph accelerometer for at ...
Purpose: Different definitions for determining non-wear time are currently used. The aim of this study was to determine the effect of the definition of ActiGraph and activPAL non-wear time on data retention and the classification of sedentary and sitting time in children. Methods: Accelerometer and inclinometer data were drawn from ...
Purpose: Recently the importance of the pattern in which sedentary time is accumulated rather than total sedentary time has been established. To date, there is no consensus on the optimal definition of sedentary bouts and breaks in children. To build evidence for such definitions, we examined the association of various ...
Purpose: To evaluate the associations between physical activity, sedentary behavior and cognitive functions in children. Methods: 230 Finnish children (mean age 12.2 years; 56% girls) participated in the study. Self-reported moderate to vigorous physical activity (MVPA) and screen time were evaluated with the questions used in the “WHO Health Behavior in School-aged Children” ...
Background: It well established that sedentarism (SED) adversely affects children´s health. Further, SED is a complex behavior and likely influenced by individual- and school-level predictors. The International Study of Childhood Obesity, Lifestyle, and Environment (ISCOLE) aims to determine the relationship between lifestyle characteristics and obesity in children, and ...
Background: Objective measures of sedentary behavior (SB) have been validated and used in a number of studies. However, these devices are limited in their ability to provide contextual information regarding the nature of SB. The Sedentary Behavior Record (SBR) is an adaptation of the 3-day Physical Activity Record for quantifying ...
Background: Obesity has been a significant public health concern among US adults. Recently, a great attention has been given to the sedentary behavior (SB) in relation to obesity; however, controversial results have been reported due to the use of less accurate measures of SB and obesity in adults. Purpose: ...
Background: The pediatric obesity epidemic has intensified the awareness of decreased physical activity and increased sedentary behavior as a major pubic health concern. While the research clearly shows ethnic disparities in obesity risk, very few have examined ethnic differences in physical activity. Most of these studies conducted were in ...
Background: Physical activity (PA) has long been associated with reduced all-cause and cardiovascular disease (CVD) mortality. More recently, time spent in sedentary behaviours has emerged as an independent risk factor for all-cause and CVD mortality. It is not well known if meeting PA guidelines reduces the amount of time spent ...
Background: Observational studies have shown that individuals can be both highly sedentary and highly active, and active people sit as much as those who do not meet the physical activity guidelines. It is not known how sedentary behavior changes in response to significant exercise training, such as training for ...
