The Effect of a Healthy Lifestyle on Future Physical Functioning in Midlife Women

  • Published on Feb 2017

Purpose: This study aimed to examine the prospective association between healthy lifestyle behaviors and objectively measured physical function in midlife women. Methods: Participants included 1769 racially/ethnically diverse women, ages 56–68 yr, from the Study of Women's Health Across the Nation cohort. Physical function was assessed at the 13th follow-up visit ...


Effects of supervised aerobic and strength training in overweight and grade I obese pregnant women on maternal and foetal health markers: the GESTAFIT randomized controlled trial

  • Published on Sep 29, 2016

Background: During pregnancy, a sedentary lifestyle may have negative consequences on maternal and foetal health status. The main objective of this project is to assess the effects of an exercise intervention in overweight and grade I obese pregnant on maternal and foetal health markers. Methods/Design: The present study aims ...


Physical activity and not sedentary time per se influences on clustered metabolic risk in elderly community-dwelling women

  • Published on Apr 7, 2017

Introduction: Whether amount of time spent in sedentary activities influences on clustered metabolic risk in elderly, and to what extent such an influence is independent of physical activity behavior, remain unclear. Therefore, the aim of the study was to examine cross-sectional associations of objectively assessed physical activity and sedentary behavior ...


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 ...


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, ...


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 ...


Objectively measured physical activity predicts subsequent energy intake in 300 women

  • Published on Jul 28, 2016

To determine if 7 d physical activity (PA) predicts energy intake over the same days and if PA on a given day predicts energy intake on the same day, the next day or subsequent days. A 7 d prospective investigation. PA was measured using accelerometers worn for seven consecutive days. During the ...


Using accelerometers to measure physical activity in large-scale epidemiological studies: issues and challenges

  • Published on Feb. 2014

Background: The current guidelines for aerobic activity require that adults carry out ≥150 min/week of moderate-intensity physical activity, with a large body of epidemiological evidence showing this level of activity to decrease the incidence of many chronic diseases. Less is known about whether light-intensity activities also have such ...


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 ...
