Abstract

Introduction: Sarcopenia is a progressive and generalized disease of skeletal muscle, which causes a decrease in muscle mass, strength and function during aging.
Objective: To assess body composition by BIA in older adults with/without sarcopenia, to assess body composition by BIA in older adults diagnosed with/without sarcopenia and make comparisons.
Methods: BIA measurements were made in 74 older adults, aged 60 years or older, of both sexes, determining their body composition by age groups and sex and sarcopenic adults were compared with healthy adults. The mean values of body composition were analyzed, to determine the effect of their values by age groups and sex. Processing was performed using IBM SPSS, version 23.
Results: One third of the sample had decreased skeletal muscle mass; almost two-thirds were women. MME decreased between 60 and 79 years of age in sarcopenic women and healthy men and up to 89 years of age in sarcopenic men and healthy women. %FMM increased between 60 and 79 years, regardless of the presence or not of the Sarcopenia and similarly, the FFM decreased between 60 and 89 years and increased in sarcopenic women between 80 and 89 and in healthy men between 70 and 79 years of age.
Conclusion: Body composition showed differences in age groups diagnosed with Sarcopenia and in healthy people, depending on sex and age group in some cases (%FM and FFM), but not in SMM. Sex was the factor that most influenced variations in body composition, in adults diagnosed with Sarcopenia and in healthy adults.
