Journal ArticleDOI
Physiological complexity underlying heart rate dynamics and frailty status in community-dwelling older women.
Paulo H.M. Chaves,Ravi Varadhan,Lewis A. Lipsitz,Phyllis K. Stein,B. Gwen Windham,Jing Tian,Lee A. Fleisher,Jack M. Guralnik,Linda P. Fried +8 more
TL;DR: To assess whether less physiological complexity underlying regulation of heart rate dynamics, as indicated by lower approximate entropy for heart rate (ApEnHR), is associated with frailty, ApEnHR was assessed.
Journal ArticleDOI
Gait alterations associated with walking impairment in people with peripheral arterial disease with and without intermittent claudication.
Mary M. McDermott,Sara M. Ohlmiller,Kiang Liu,Jack M. Guralnik,Gary J. Martin,William H. Pearce,Philip Greenland +6 more
TL;DR: Gait alterations associated with impaired walking endurance in patients with and without lower‐extremity peripheral arterial disease are described and whether the Caltrac accelerometer provides a valid measure of physical activity in PAD is determined.
Journal ArticleDOI
Bone density and hemoglobin levels in older persons: Results from the InCHIANTI study
Matteo Cesari,Marco Pahor,Fulvio Lauretani,Brenda W. H. J. Penninx,Benedetta Bartali,Roberto Russo,Antonio Cherubini,Richard J. Woodman,Stefania Bandinelli,Jack M. Guralnik,Luigi Ferrucci +10 more
TL;DR: It is concluded that anemia and low hemoglobin levels are negatively and independently associated with bone mass and density.
Journal ArticleDOI
Lower Extremity Performance Is Associated with Daily Life Physical Activity in Individuals with and without Peripheral Arterial Disease
Mary M. McDermott,Philip Greenland,Luigi Ferrucci,Michael H. Criqui,Kiang Liu,Leena Sharma,Cheeling Chan,Lillian Celic,Aparna Priyanath,Jack M. Guralnik +9 more
TL;DR: In people with and without PAD who have impaired lower extremity performance, reduced physical activity levels may contribute to subsequent disability.
Journal ArticleDOI
Variation in Thresholds for Reporting Mobility Disability Between National Population Subgroups and Studies
TL;DR: Estimating thresholds on tested performance at which self-reports change from one category to another, across a range of sociodemographic subgroups shows evidence of differences in thresholds for reporting mobility disability, especially across age and income groups in older Americans.
