Epidemiological Transition in Physical Activity and Sedentary Time in Children

  • Published on May, 2019

Background To determine if children’s moderate to vigorous physical activity (MVPA) and sedentary time varied across levels of household income in countries at different levels of Human Development Index (HDI), consistent with the theory of epidemiological transition. Methods Data from 6548 children (55% girls) aged 9–11 years from 12 countries at different HDI ...


Characterization and Agreement Between Application of Mobile Ecological Momentary Assessment (mEMA) and Accelerometry in the Identification of Prevalence of Sedentary Behavior (SB) in Young Adults

  • Published on April 9, 2019

Introduction Sedentary behavior (SB) is defined as any activity performed during “awake” time with low energy expenditure (equal to or below 1.5 metabolic equivalents – MET’s) in a sitting or reclining position (Sedentary Behaviour Research Network, 2012; Tremblay et al., 2017). Studies have shown that this behavior is highly prevalent among adults, and ...


Concurrent validity of the Fitbit for assessing sedentary behavior and moderate-to-vigorous physical activity.

  • Published on February 7, 2019

Background Recent advances in sensor technologies have promoted the use of consumer-based accelerometers such as Fitbit Flex in epidemiological and clinical research; however, the validity of the Fitbit Flex in measuring sedentary behavior (SED) and physical activity (PA) has not been fully determined against previously validated research-grade accelerometers such as ...


Can Replacing Sitting Time with Standing Time Improve Adolescents’ Cardiometabolic Health?

  • Published on Aug 27, 2019

Abstract: This study aimed to assess the effects of isotemporal replacement of sitting time (SIT) with standing (STA) on cardiometabolic biomarkers. In this cross-sectional study, male adolescents wore the GT3X+ activity monitor for 7 days to measure the SIT and STA. Moderate-to-vigorous physical activity (MVPA) was estimated by a youth-specific ...




Objectively Measured Physical Activity and Sedentary Time Are Associated With Cardiometabolic Risk Factors in Adults With Prediabetes: The PREVIEW Study

  • Published on Feb. 20, 2019

Objective: The aim of the present cross-sectional study was to examine the association among physical activity (PA), sedentary time (ST), and cardiometabolic risk in adults with prediabetes. Research Design and Methods: Participants (n = 2,326; 25–70 years old, 67% female) from eight countries, with a BMI >25 kg ⋅ m−2 and impaired fasting glucose (5.6–6.9 mmol ⋅ L−1) ...


Promoting physical activity in regional and remote cancer survivors (PPARCS) using wearables and health coaching: randomised controlled trial protocol

  • Published on May 24, 2019

Introduction: Physically active cancer survivors have substantially less cancer recurrence and improved survival compared with those who are inactive. However, the majority of survivors (70%–90%) are not meeting the physical activity (PA) guidelines. There are also significant geographic inequalities in cancer survival with poorer survival rates for the third of Australians ...



Measuring Time in the Office Using Bluetooth Sensors: Feasibility and Validity Considerations

  • Published on Mar, 2019

The office is a key setting for intervening to reduce sitting, therefore office-specific activity measures are needed to evaluate interventions. We tested whether valid measures of office time and office-specific activities could be obtained using Bluetooth sensing with a variety of sampling intervals, receiver wear positions, and beacon placements. Workers ...
