Validity of three accelerometers to investigate lying, sitting, standing and walking

  • Published on May 23, 2019

Background: Hospital stays are associated with high levels of sedentary behavior and physical inactivity. To objectively investigate physical behavior of hospitalized patients, these is a need for valid measurement instruments. The aim of this study was to assess the criterion validity of three accelerometers to measure lying, sitting, standing and ...



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 ...


Objectively measured physical activity of hospital shift workers

  • Published on Jan 22, 2018

Objectives: Shift work may alter workers' leisure-time and occupational physical activity (PA) levels, which might be one of the potential underlying mechanisms of the negative health effects of shift work. Therefore, we compared objectively measured PA levels between hospital shift and non-shift workers. Methods: Data were used from Klokwerk+, a ...


Effect of skin-to-skin contact on parents’ sleep quality, mood, parent-infant interaction and cortisol concentrations in neonatal care units: study protocol of a randomised controlled trial

  • Published on Aug 1, 2018

Abstract Introduction: Separation after preterm birth is a major stressor for infants and parents. Skin-to-skin contact (SSC) is a method of care suitable to use in the neonatal intensive care unit (NICU) to minimise separation between parents and infants. Less separation leads to increased possibilities for parent-infant interaction, provided that ...


Accelerometric estimates of physical activity vary unstably with data handling.

  • Published on Nov 6, 2017

Background: Because of unreliable self-report, accelerometry is increasingly used to objectively monitor physical activity (PA). However, results of accelerometric studies vary depending on the chosen cutpoints between activity intensities. Population-specific activity patterns likely affect the size of these differences. To establish their size and stability we apply three sets of ...



Association of physical activity with lung function in lung-healthy German adults: results from the KORA FF4 study

  • Published on December 28, 2018

BACKGROUND In lung disease, physical activity (PA) yields beneficial health effects, but its association with the function of healthy lungs has rarely been studied. We investigated the association of accelerometer-based PA with spirometric indices, maximal inspiratory mouth pressure (PImax) and lung diffusion capacity in lung-healthy adults. METHODS In total, 341 apparently ...


Effectiveness of a Behavior Change Program on Physical Activity and Eating Habits in Patients With Hypertension: A Randomized Controlled Trial

  • Published on December 12, 2017

Background This study aimed to analyze the effect of a behavior change program, called Vida Ativa Melhorando a Saúde (VAMOS), on physical activity, eating habits, and quality of life in patients with hypertension. Methods A randomized controlled trial was carried out in 90 patients with hypertension (57.8 ± 9.9 y). They were randomly ...
