Background: In an aging population, regular physical activity (PA) and exercise have been recognized as important factors in maintaining physical function and thereby preventing loss of independence and disability. However, (older) adults spent the majority of their day sedentary and therefore insight into the consequences of sedentary behavior on physical function, independent of PA, is warran...

Most studies of sedentary behavior have focused on television use or screen time. This study aims to examine adolescent girls' participation in a variety of recreational sedentary behaviors (e.g., talking on the phone and hanging around), and their association with physical activity (PA), dietary behaviors, and body mass index. Data were from a sample of 283 adolescent girls. Recreational seden...

OBJECTIVE 1) To synthesize the current observational evidence for the association between sedentary behavior and health outcomes using information from systematic reviews. 2) To assess the methodological quality of the systematic reviews found. METHODOLOGY/PRINCIPAL FINDINGS Medline; Excerpta Medica (Embase); PsycINFO; and Web of Science were searched for reviews published up to September 201...

Although prolonged sitting appears as a novel risk factor related to health outcomes for all ages, its association needs to be replicated in occupational conditions. This study explored the associations between sedentary behavior and four noncommunicable diseases (NCDs) as well as two cardiometabolic risk factors (CMRFs) among workers in a petroleum company, Thailand. All workers were invited t...

BACKGROUND Relatively little is known regarding after-school behavior. This study examined after-school active and sedentary behaviors among youth participating in the Study of Early Child Care and Youth Development. METHODS An interview guided time-use approach was used to obtain detailed longitudinal information about after-school (3-6 PM) behavior of a mixed gender cohort (n = 886) at ages...

A sedentary lifestyle can be defined as “a type of lifestyle with little or no physical activity”. Sedentary behavior includes reading, computer use, watching television, office work, and cell phone use. A similar but somewhat different term is screen time. This is the sum of the time spent viewing a television, computer monitor, mobile device, or other screen. Prospective evidence is accumulat...

INTRODUCTION Insights into the diurnal patterns of sedentary behavior and the identification of subgroups that are at increased risk for engaging in high levels of sedentary behavior are needed to inform potential interventions for reducing older adults' sedentary time. Therefore, we examined the diurnal patterns and sociodemographic correlates of older adults' sedentary behavior(s). METHODS ...

OBJECTIVE To identify the prevalence of factors associated with insufficient physical activity levels and sedentary behavior among adolescents. METHODS In this cross-sectional study 4,210 students (14-19 years old) attending public high-schools were selected using random two-stage cluster sampling. Data were collected by using the Global School-based Student Health Survey. Subjects who report...

Diet, physical activity (PA) and sedentary behavior are important, yet modifiable, determinants of obesity. Recent research into the clustering of these behaviors suggests that children and adolescents have multiple obesogenic risk factors. This paper reviews studies using empirical, data-driven methodologies, such as cluster analysis (CA) and latent class analysis (LCA), to identify clustering...
