Abdominal obesity as a mediator of the influence of physical activity on insulin resistance in Spanish adults

  • Published on Nov. 19, 2015

Objective: The aim of the study was to analyze the relationship between moderate-to-vigorous physical activity (MVPA) and insulin resistance (IR) in Spanish adults and to examine whether this relationship is mediated by abdominal obesity (waist circumference — WC). Methods: The cross-sectional study included 1162 healthy subjects belonging to the EVIDENT study (mean ...


Dog walking among adolescents: Correlates and contribution to physical activity

  • Published on Nov. 19, 2015

Purpose: To assess the association of dog walking with adolescents' moderate-to-vigorous physical activity (MVPA) and body mass index (BMI), and identify correlates of dog walking. Methods/design: Participants were 12–17 year-olds (n = 925) from the Baltimore, MD and Seattle, WA regions. Differences in accelerometer-assessed minutes/day of MVPA and self-reported BMI (percentile) ...


The objective measurement of physical activity and sedentary behaviour in 2–3 year olds and their parents: a cross-sectional feasibility study in the bi-ethnic Born in Bradford cohort

  • Published on Nov. 11, 2015

Background: The reported lower physical activity (PA) levels of British South Asians (SA) are suggested as a key influence in their increased risk of non-communicable diseases compared to their White British peers. Differences in objectively measured PA and sedentary behaviour (SB) between these ethnic groups have been observed during childhood (...


Locations of physical activity as assessed by GPS in young adolescents

  • Published on Jan. 2016

Objectives: To compare adolescents’ physical activity at home, near home, at school, near school, and at other locations. Methods: Adolescents (N = 549) were ages 12 to 16 years (49.9% girls, 31.3% nonwhite or Hispanic) from 447 census block groups in 2 US regions. Accelerometers and Global Positioning System devices assessed minutes of and proportion of time spent ...


A Randomised Controlled Trial to Reduce Sedentary Time in Young Adults at Risk of Type 2 Diabetes Mellitus: Project STAND (Sedentary Time ANd Diabetes)

  • Published on Dec. 1, 2015

Aims: Type 2 diabetes mellitus (T2DM), a serious and prevalent chronic disease, is traditionally associated with older age. However, due to the rising rates of obesity and sedentary lifestyles, it is increasingly being diagnosed in the younger population. Sedentary (sitting) behaviour has been shown to be associated with greater risk ...


Effect of Structured Physical Activity on Prevention of Major Mobility Disability in Older Adults The LIFE Study Randomized Clinical Trial

  • Published on June 18, 2014

Importance: In older adults reduced mobility is common and is an independent risk factor for morbidity, hospitalization, disability, and mortality. Limited evidence suggests that physical activity may help prevent mobility disability; however, there are no definitive clinical trials examining whether physical activity prevents or delays mobility disability. Objective: To test ...


Variability of Objectively Measured Sedentary Behavior.

  • Published on Nov. 24, 2015

Introduction: The primary purpose of this study was to evaluate variability of sedentary behavior (SB) throughout a 7-day measurement period and to determine if < 7-days of SB measurement would be comparable to the typical 7-day measurement period. Methods: Retrospective data from Ball State University's Clinical Exercise Physiology Laboratory on 293 ...


Concurrent and predictive validity of physical activity measurement items commonly used in clinical settings– data from SCAPIS pilot study

  • Published on Sept. 28, 2015

Background: As the understanding of how different aspects of the physical activity (PA) pattern relate to health and disease, proper assessment is increasingly important. In clinical care, self-reports are the most commonly used assessment technique. However, systematic comparisons between questions regarding concurrent or criterion validity are rare, as are measures ...


Accelerometer-Derived Pattern of Sedentary and Physical Activity Time in Persons with Mobility Disability: National Health and Nutrition Examination Survey 2003 to 2006

  • Published on July 14, 2015

Objectives: To describe objectively determined sedentary and activity outcomes (volume and pattern) and their associations with cardiometabolic risk biomarkers in individuals with and without mobility disability. Design: Cross-sectional Setting: Population based Participants: Community-dwelling older adults (≥60) living in the United States who were participants in the 2003 to 2004 or 2005 to 2006 National Health ...
