Associations between objectively measured physical activity intensity in childhood and measures of subclinical cardiovascular disease in adolescence: prospective observations from the European Youth Heart Study

  • Published on April 13, 2013

Background and Aim: No prospective studies have investigated the association between physical activity (PA) and carotid subclinical cardiovascular disease across childhood. Therefore, the primary aim was to investigate the association between PA intensity across childhood and carotid intima media thickness (cIMT) and stiffness in adolescence. Second, we included a clustered ...

Assessing Physical Activity in Persons with Rheumatoid Arthritis Using Accelerometry

  • Published on August 2010

Purpose: To empirically investigate if the nonwear threshold and the ‘valid day’ definition for accelerometer data from the general adult US population are appropriate for accelerometer data from persons with rheumatoid arthritis (RA). Methods: This study analyzed data from 107 persons with RA participating in the baseline (2006-2008) accelerometer assessment from ...

Association Between Physical Activity and Inflammatory Markers Among U.S. Adults with Chronic Obstructive Pulmonary Disease

  • Published on Dec. 20, 2013

Purpose: Chronic obstructive pulmonary disease (COPD) may cause not only inflammation in the lungs but also systemic effects. One potential strategy to reduce systemic inflammation and attenuate disease progression is physical activity (PA). However, no nationally representative studies, to our knowledge, have examined the association between objectively measured physical activity ...

Treatment options for type 2 diabetes in adolescents and youth: a study of the comparative efficacy of metformin alone or in combination with rosiglitazone or lifestyle intervention in adolescents with type 2 diabetes

  • Published on April 8, 2007

Abstract: Despite the increased prevalence of type 2 diabetes mellitus (T2DM) in the pediatric population, there is limited information about the relative effectiveness of treatment approaches. This article describes the rationale and design of a National Institutes of Health-sponsored multi-site, randomized, parallel group clinical trial designed to test the hypothesis ...

Validity of physical activity monitors during daily life in patients with COPD

  • Published on Nov. 1, 2013

Background: Symptoms during physical activity and physical inactivity are hallmarks of chronic obstructive pulmonary disease (COPD). Our aim was to evaluate the validity and usability of six activity monitors in patients with COPD against the doubly labelled water (DLW) indirect calorimetry method. Methods: 80 COPD patients (mean±SD age 68±6 years and ...

Reallocating time to sleep, sedentary behaviors, or active behaviors: associations with cardiovascular disease risk biomarkers, NHANES 2005-2006.

  • Published on Jan. 17, 2014

Abstract: Sleep and sedentary and active behaviors are linked to cardiovascular disease risk biomarkers, and across a 24-hour day, increasing time in 1 behavior requires decreasing time in another. We explored associations of reallocating time to sleep, sedentary behavior, or active behaviors with biomarkers. Data (n = 2,185 full sample; n = 923 fasting subanalyses) ...
