Association between intrinsic capacity and weak muscle strength in naval medical center older adults

Purpose: The purpose of this study was to determine the association between intrinsic capacity (IC) and dynapenia in older adults in outpatient clinics at the Naval Medical Center. Design/methodology/approach: The study design was observational, analytical and retrospective. The study from which the collected data came was an observational analytical cohort, whose main objective was to describe the factors associated with frailty in older adults. The population comes from the Peruvian Naval Medical Center. This was a retrospective, observational, analytical study of the factors associated with frailty in older adults from the Naval Medical Center of Peru. Findings: Data from 1667 participants was analyzed, 682 of them were female (40.9%) and 985 were male (50.1%); regarding age, most participants had 71–80 years (n = 761, 45.6%). Prevalence of the dynapenia was 34.5% (n = 576), and 80.08% (n = 1335) had an altered IC. In an adjusted model using Poisson regression, a prevalence ratio of 2.76 (95%, CI 2.06–3.70) was found. In conclusion, there is an association between IC and dynapenia in older adults. Originality/value: In Latin America and Peru, there is limited information regarding this topic and tools for the evaluation of IC.
