Low vitamin D and high parathyroid hormone levels as determinants of loss of muscle strength and muscle mass (sarcopenia): the Longitudinal Aging Study Amsterdam. (2003, neutral): “some (9, 11, 39–41) but not all (33, 42) studies.”
Dual Energy X-Ray Absorptiometry Body Composition Reference Values from NHANES (2009, background): “Reference curves for appendicular lean mass divided by height(2) were developed because this DXA measure is a good surrogate for skeletal muscle mass and a possible index of sarcopenia [19].”
Prevalence of sarcopenia in the world: a systematic review and meta- analysis of general population studies (2017, positive): “8% of the women of the same age group corresponded to the definitions of sarcopenia [1, 15, 16].”
Invited review: Aging and sarcopenia. (2003, methodology): “(58) used DEXA to quantify appendicular skeletal muscle mass in 195 women aged 64–93 yr and 142 men aged 64–92 yr.”
Sarcopenia: European consensus on definition and diagnosis (2010, background): “What is the evidence that age-related sarcopenia fits the current definition of a geriatric syndrome? Sarcopenia is prevalent in older populations [7, 8].”
Sarcopenia, Dynapenia, and the Impact of Advancing Age on Human Skeletal Muscle Size and Strength; a Quantitative Review (2012, background): “When similarly measured in a Caucasian New England population 53% of men and 31% of women aged over 80 years were sarcopenic (Iannuzzi-Sucich et al., 2002).”
