Prevalence of dynapenia and presarcopenia related to aging in adult community-dwelling Mexicans using two different cut-off points.

Abstract

To estimate the prevalence of dynapenia, presarcopenia, and sarcopenia in a Mexican community using two different cutoffs. This cross-sectional study included 724 subjects (521 women and 203 men) adults≥50years community-dwelling from Mexico City. We determined the prevalence of different muscle-related syndromes. Muscle strength was measured with handgrip strength and muscle mass was estimated by bioelectrical impedance. For the diagnosis of sarcopenia and presarcopenia, two criteria were used: (1) the cut-off points proposed by the European Working Group on Sarcopenia in Older People (EWGSOP) and (2) the cut-off points less than two standard deviations for gender-specific mean of Mexicans young adults. Muscle mass decreases with age, but not as rapid as muscle strength. With the specific Mexican cut-off points, the general prevalences were: 27.4% for dynapenia (n=199), 12.8% for presarcopenia (n=93), and 6.6% for sarcopenia (n=48). In contrast, the prevalences were higher when we used the cut-off points for Caucasians (EWGSOP): 33.9% for dynapenia (n=246), 38.1% for presarcopenia (n=276), and 15.2% for sarcopenia (n=110). Diagnoses of dynapenia, presarcopenia, and sarcopenia should be estimated from cut-off points of the specific population; otherwise, it might be overestimated or underestimated. Early diagnosis of any of these conditions in community can prevent the occurrence of adverse effects.
