Calibrating physical activity intensity for hip-worn accelerometry in women age 60 to 91 years: The Women's Health Initiative OPACH Calibration Study

  • Published on 2015

Objective: We conducted a laboratory-based calibration study to determine relevant cutpoints for a hip-worn accelerometer among women ≥60 years, considering both type and filtering of counts. Methods: Two hundred women wore an ActiGraph GT3X+ accelerometer on their hip while performing eight laboratory-based activities. Oxygen uptake was measured using an Oxycon ...


Comparison of physical activity assessed using hip- and wrist-worn accelerometers

  • Published on Feb 2016

Objectives: It is unclear how physical activity estimates differ when assessed using hip- vs wrist-worn accelerometers. The objective of this study was to compare physical activity assessed by hip- and wrist-worn accelerometers in free-living older women. Design: A cross-sectional study collecting data in free-living environment. Methods: Participants were from the ...


Independent and joint associations of physical activity and fitness with fibromyalgia symptoms and severity: The al-Ándalus project

  • Published on 12 Sep, 2016

We examined independent and joint associations of objectively measured physical activity (PA) and physical fitness (PF) with pain, fatigue and the overall impact of fibromyalgia in 386 fibromyalgia women aged 51.2 ± 7.6 years. Levels of PA (light, moderate and vigorous) and PF were measured with triaxial accelerometry and the Senior Fitness Test, respectively. ...


The Relationship between Time of Day of Physical Activity and Obesity in Older Women

  • Published on Apr 2016

Background: Physical activity is important for maintaining healthy weight. The time of day when exercise is performed—a highly discretionary aspect of behavior—may impact weight control, but evidence is limited. Thus, we examined the association between the timing of physical activity and obesity risk in women. Methods: A cross-sectional ...




Patterns of Accelerometer-Assessed Sedentary Behavior in Older Women

  • Presented on May 29, 2013

Purpose To examine characteristics of accelerometer-assessed sedentary behavior among older women. Methods An ancillary study to the Women’s Health Study is collecting 7 days of accelerometer-assessed (Actigraph GT3X+) physical activity and sedentary behavior data in ~15,000 women. This analysis includes data from the first 5,032 (mean age, 70.1 yr) women with ≥4 days ...
