Seasonal variation in objectively measured physical activity, sedentary time, cardio-respiratory fitness and sleep duration among 8–11 year-old Danish children: a repeated-measures study

  • Published on Sept. 8, 2013

Background Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design.

Physical Activity, Sedentary Behavior and C-Reactive Protein in Pregnancy

  • Published on July 15, 2013

Introduction: Elevated C-reactive protein (CRP) is associated with adverse pregnancy outcomes. In non-pregnant populations, physical activity has been inversely associated with CRP, but this association has not been evaluated during pregnancy. The purpose of this study was to evaluate the association between objectively measured physical activity, sedentary behavior, and CRP ...
