Relationship of Meeting Physical Activity Guidelines and Quality Adjusted Life Years

  • Presented on Oct. 27, 2013

Background/Purpose Regular physical activity is associated with reduced chronic disease burden and mortality. Recognizing the importance of physical activity, there are US federal guidelines for adults that also include persons with arthritis. Improving physical activity may be key to improving overall public health and reducing health care spending. Quality ...


A Longitudinal Study Evaluating the Effect of Exacerbations on Physical Activity in Patients with COPD

  • Published on Sept. 20, 2013

Background Physical inactivity is common in stable COPD and independently predicts poor outcomes. Longitudinal assessments of physical activity in outpatients with COPD, covering periods of stability and exacerbations, have not been evaluated previously. Methods Patients with clinically-stable COPD and a history of 2 or more clinical exacerbations in the preceding 12 months ...


Annual recollection of exacerbations in patients with COPD: Impact on physical activity

  • Presented on Sept. 9, 2013

Rationale The number of exacerbations in the previous year has shown to be the best predictor of new exacerbations. The ability to recall exacerbations may lead to misclassification of patients and may have consequences on patients’ phenotype. Methods 47 patients with COPD (FEV1 65±21%pred) reported on a monthly basis all health ...


Agreement of classification of COPD patients’ physical activity with two activity monitors

  • Presented on Sept. 8, 2013

Rationale It is unclear whether different activity monitors provide similar classification of physical activity (PA) in patients with COPD. Aim To test whether similar PA classification of patients would be obtained when using 2 valid activity monitors. Methods We assessed PA for 4 weeks with Actigraph [(ACT: Steps and vector magnitude units (...


Sustained vs. Shorter Bouts of Physical Activity and Cardiovascular Health

  • Presented on June 17, 2013

Introduction Physical activity is known to prevent cardiovascular disease (CVD). However, the relative importance of accumulating physical activity in sustained bouts versus shorter bouts in terms of CVD risk is yet to be determined. Purpose The aim of this study was to investigate the relationship between moderate-to-vigorous physical activity (MVPA), ...


Real-time Visual Activity Feedback For Physical Activity Improvement In Cancer Patients

  • Presented on June 1, 2013

Physical activity is becoming increasingly recognized as valuable to cancer patients during treatment and rehabilitation. Therefore strategies and measures to encourage patients to become more active and to achieve physical activity recommendations are of great importance. Purpose The study evaluated an accelerometer based biofeedback device by measuring the change of ...


Sedentary/active Behaviors And Cardiometabolic Risk: Protective Effects Of Sleep Duration, Nhanes 2005-2006

  • Presented on May 29, 2013

Optimal sleep duration (7-8h), moderate-to-vigorous intensity physical activity (MVPA) and light-intensity activity are beneficially associated with cardiometabolic outcomes and related biomarkers, while sedentary time and long (≥9h) or short (<7h) sleep duration are detrimentally associated. Purpose This study examined whether sleep duration modified the relationship between both sedentary/...


Physical Activity And Sedentary Behaviour In Scottish Youth With Type 1 Diabetes

  • Presented on May 29, 2013

Physical activity can benefit the health of youth with Type 1 diabetes. Despite the benefits some studies have found patients do not always meet the physical activity recommendation of 60 minutes of moderate-to-vigorous physical activity (MVPA) per day. Physical activity and sedentary behaviour have not been measured previously in Scottish youth with ...


Relationship Between Physical Activity Patterns And Key Cardiopulmonary Exercise Testing Variables In Patients With Heart Failure

  • Presented on May 31, 2013

Purpose A hallmark characteristic of heart failure (HF) is reduced physical activity (PA) patterns and functional capacity. The relationship between key cardiopulmonary exercise testing (CPX) variables and PA patterns has not been investigated. To evaluate PA patterns in patients with ischemic HF and its relationship to peak oxygenconsumption (VO2), the ...


Associations Between Objectively Measured Physical Activity Intensity Across Childhood and Measures of Sub-Clinical Atherosclerosis in Adolescence: The European Youth Heart Study

  • Presented on 25 October 2012

Aim Little is known of the longitudinal association between sub-clinical atherosclerosis from childhood to adolescence. Therefore, the aim was investigate the association between physical activity (PA) intensity across childhood and sub-clinical atherosclerosis in adolescence. Methods This was a prospective study of a sample of 236 children (baseline age 8-10 y) with ...
