Background: Estimates of biological age derived from DNA-methylation patterns-known as the epigenetic clock-are associated with mortality, physical and cognitive function, and frailty, but little is known about their relationship with sedentary behavior or physical activity. We investigated the cross-sectional relationship between two such estimates of biological age and objectively measured sedentary and walking behavior in older people. Methods: Participants were 248 members of the Lothian Birth Cohort 1936...

INTRODUCTION: Inactivity and weight regain are serious problems post-bariatric surgery. Nearly half of waking time is spent at work, representing an opportunity to accumulate physical activity and help avoid weight regain. PURPOSE: The purpose of this study is to evaluate potential differences in physical activity and sedentary time by employment status post-bariatric surgery. METHODS: A total of 48 adults (employed (n = 19), unemployed (n = 29)) aged 50...

BACKGROUND: The widely accepted definition of sedentary behaviour [SB] refers to any waking behaviour characterized by an energy expenditure ≤1.5 metabolic equivalents [METs] while in a sitting or reclining posture. At present, there is no single field-based device which objectively measures sleep, posture and activity intensity simultaneously. The aim of this study was to develop a novel integrative procedure [INT] to combine information from two validated activity monitors on sleep, activity intensity and posture, the three key dimensions of SB...

OBJECTIVES: Prolonged sitting is a health risk factor which is ubiquitous to the workplace, and breaking up prolonged sitting is widely recommended. This study evaluated the test-retest reliability and concurrent validity of a self-report measure of duration of sitting and breaks from sitting in the workplace. DESIGN: Cross-sectional study. METHODS: Fifty-nine workers who reported spending most of their work time sitting wore an activPAL inclinometer and the ActiGraph accelerometer for eight consecutive days, and completed single-item measures of duration of sitting (min/work hour) and breaks from sitting (frequency/per work hour), twice, seven days apart...

Current measures of physical activity and sedentary behaviors such as questionnaires and functional assessments are insufficient to provide comprehensive data on older adults. In response, the use of activity monitors has increased. The purpose of this review was to summarize and assess the quality of observational literature on activity measuring of older adults using the activPAL activity monitor. Seventeen databases and a bibliography, compiled by the activPAL creators, were searched. Articles were included if they were in English, were peer-reviewed, included people 65 years or older, measured activity using the activPAL and reported at least one of the following outcomes: step count, hours upright, hours sitting/lying, hours stepping, or hours standing...

BACKGROUND: Evidence suggests youth with type 1 diabetes (T1D) have lower levels of physical activity (PA) than the general population. The ActivPals intervention aimed to support youth with T1D to lead an active lifestyle. METHODS: Twenty youth aged 7 to 16 years with T1D were recruited to a pilot randomized controlled trial. PA and quality of life (QoL) were measured using Actigraph GT3X+ monitor and Pediatric QoL scales at baseline and 1-month follow-up. A two-way, mixed ANOVA showed indicative effects of the intervention...

BACKGROUND: According to cross-sectional and acute experimental evidence, reducing sitting time should improve cardio-metabolic health risk biomarkers. Furthermore, the improvements obtained may depend on whether sitting is replaced with standing or ambulatory activities. Based on data from the Stand Up Victoria multi-component workplace intervention, we examined this issue using compositional data analysis - a method that can examine and compare all activity changes simultaneously. METHODS: Participants receiving the intervention (n=136 ≥0...

OBJECTIVES: Time spent inactive and sedentary are both associated with poor health. Self-monitoring of walking, using pedometers for real-time feedback, is effective at increasing physical activity. This study evaluated the feasibility of a new pocket-worn sedentary time and physical activity real-time self-monitoring device (SitFIT). METHODS: Forty sedentary men were equally randomised into two intervention groups. For 4 weeks, one group received a SitFIT providing feedback on steps and time spent sedentary (lying/sitting); the other group received a SitFIT providing feedback on steps and time spent upright (standing/stepping)...

PURPOSE: Pedometers, which enable self-monitoring of step counts, are effective in facilitating increases in physical activity. Similar devices which provide real-time feedback on sedentary (sitting) behavior are limited. This study aimed to develop and validate a novel device - the SitFIT - which could accurately measure and provide feedback on sedentary behavior and physical activity. METHODS: The SitFIT is a tri-axial accelerometer, developed by PAL Technologies, which is worn in the front trouser pocket...

PURPOSE: Hospital-associated deconditioning due to a combination of illness and inactivity is a serious problem for elderly adults. Here we investigate whether persistence in inflammatory status affects changes in physical function during short-term hospitalization. METHODS: This was a prospective observational study in elderly medical patients at a geriatric department. Measurements were obtained at admission and one week after admission and included de Morton Mobility Index (DEMMI) test, 30-second chair stand test (30-s CST), 4-m gait speed (4-m GST) test, handgrip strength, activity levels determined with ActivPALs, and concentrations of circulating C-reactive protein (CRP) from blood samples...

Older adults are recommended to reduce their sedentary time to promote healthy ageing. To develop effective interventions identifying when, why, and how older adults are able to change their sitting habits is important. The aim of this mixed-method study was to improve our understanding of reasons for (breaking) sedentary behavior in older adults. Thirty older adults (74.0 (±5.3) years old, 73% women) were asked about their believed reasons for (breaking) sedentary behavior, and about their actual reasons when looking at a personal storyboard with objective records of activPAL monitor data and time-lapse camera pictures showing all their periods of sedentary time in a day...

INTRODUCTION/PURPOSE: To assess the utility of measurement methods that may be more accurate and precise than traditional questionnaire-based estimates of habitual physical activity and sedentary behavior we compared the measurement properties of a past year questionnaire (AARP) and more comprehensive measures: an internet-based 24-hour recall (ACT24), and a variety of estimates from an accelerometer (ActiGraph). METHODS: Participants were 932 adults (50-74 y) in a 12-month study that included reference measures of energy expenditure from doubly labeled water (DLW) and active and sedentary time via activPAL...

This study aimed to validate measures of sedentary time in individuals with Rett syndrome. Twenty-six individuals (median [IQR] age 16.0 (9.4-20.6) years) wore an activPAL accelerometer during video-taped activities and agreement was determined between sedentary time determined by the activPAL and observation. For 11 individuals (median [IQR] age 14.5 (11.5-25.6) years), linear regression was used to determine the relationship between sedentary time recorded on the modified Bouchard activity record diary card and measured using the activPAL...
