BACKGROUND The increasing prevalence of type 2 diabetes in older adults has become a public health concern. We investigated the associations of total and domain-specific sedentary time with risk of type 2 diabetes in older adults. METHODS The sample comprised 1046 older people (aged ≥65 years). Analyses were performed using cross-sectional data collected via computer-assisted telephone-based ...

BACKGROUND Greater time spent sedentary is linked with increased risk of breast, colorectal, ovarian, endometrial, and prostate cancers. Given steadily increasing rates of mobile phone ownership, mobile phone interventions may have the potential to broadly influence sedentary behavior across settings. OBJECTIVE The purpose of this study was to examine the short-term impact of a mobile phone i...

In sedentary individuals, H(1) receptors mediate the early portion of postexercise skeletal muscle hyperemia, whereas H(2) receptors mediate the later portion. It is not known whether postexercise hyperemia also presents in endurance-trained individuals. We hypothesized that the postexercise skeletal muscle hyperemia would also exist in endurance-trained individuals and that combined blockade o...

BACKGROUND Sedentary time (too much sitting, as distinct from lack of exercise) is a prevalent risk to health among older adults. PURPOSE Examine the feasibility of an intervention to reduce and break up sedentary time in older adults. DESIGN A pre-experimental (pre-post) study. SETTING/PARTICIPANTS A total of 59 participants aged ≥60 years from Brisbane, Australia. Data were collected be...

Sedentary behavior is a cluster of behaviors adopted in a sitting or lying posture where little energy is being expended. Sedentary behavior is a risk factor for health independent to inactivity. Currently, there are no published systematic reviews on the prevalence of sedentary behavior objectively measured in, or subjectively reported by, older adults. The aim of this systematic review was to...

Sedentary behaviour is considered to be a major factor impacting a number of health outcomes while use of technology in the workplace is increasingly contributing to the amount of sedentary time. Even if guidelines on the amount of physical activity are followed outside of workplace, sedentary work style still has a deleterious impact on health. There have been a number of studies that investig...

Sedentary behaviour is an emerging risk factor for poor health. This study aimed to identify ecological determinants of sedentary behaviour, for which evidence is currently scarce. The study participants were community dwelling adults from, respectively, the Lothian Birth Cohort 1936 (n = 271, mean age 79) and the 1930s (n = 119, mean age 83) and 1950s (n = 310, mean age 64) cohorts of the West...

BACKGROUND Both physical activity and sedentary behaviour have been individually associated with health, however, the extent to which the combination of these behaviours influence health is less well-known. The aim of this study was to examine the associations of four mutually exclusive categories of objectively measured physical activity and sedentary time on markers of cardiometabolic health ...

AIM The aim of this study was to investigate the potential associations of reallocating 30 minutes sedentary time in long bouts (>60 min) to sedentary time in non-bouts, light intensity physical activity (LPA) and moderate- to vigorous physical activity (MVPA) with cardiometabolic risk factors in a population diagnosed with prediabetes or type 2 diabetes. METHODS Participants diagnosed with p...

BACKGROUND Accelerometer-based activity monitors are widely used in research and surveillance applications for quantifying sedentary behavior (SB) and physical activity (PA). Considerable research has been done to refine methods for assessing PA, but relatively little attention has been given to operationalizing SB parameters (i.e., sedentary time and breaks) from accelerometer data - particula...
