Disability, physical activity, and muscle strength in older women: The women's health and aging study
Abstract Objective: To study associations of motor disability, physical activity, and muscle strength in older women, in particular to investigate whether model of spiraling decrease is expressed in the data. Design: Cross-sectional analysis using data from the base-line measurements of The Women's Health and Aging Study (WHAS). Setting: Participants' homes. Participants: A total of 1,002 disabled women aged 65 years and older living in the community. Outcome Measures: Motor disability was measured by the number of self-reported difficulties in grasping, lifting 101b, walking across a small room, walking 14 mile, climbing 10 steps, and doing heavy housework. Level of physical activity was d…
Magnesium and muscle performance in older persons: the InCHIANTI study1–3
BACKGROUND The role of magnesium in maintaining muscle integrity and function in older adults is largely unknown. OBJECTIVE We aimed to investigate the relation between serum magnesium concentrations and muscle performance in older subjects. DESIGN Data are from the baseline examination conducted between September 1998 and March 2000 of the InCHIANTI (aging in the Chianti area) study, a prospective epidemiologic survey of risk factors for late-life disability. From among 1453 randomly selected community residents completing a home interview, 1138 men (46%) and women (aged 66.7 +/- 15.2 y; x +/- SD) with complete data on muscle performance and serum magnesium who were not severely cognitivel…
