Cognitive impairment is independently associated with definitive and possible sarcopenia in hospitalized older adults: The prevalence and impact of comorbidities.

Older adults often present with several comorbidities, including sarcopenia. However, the prevalence of sarcopenia and its associations with other comorbidities in hospitalized older adults are unknown. The present study aimed to determine the prevalence of sarcopenia, and its associations with other comorbidities in hospitalized older adults. The present cross-sectional study included 619 patients admitted to a geriatric hospital. The prevalence of comorbidities in the presence and absence of sarcopenia, nutritional status (according to body mass index and the Mini-Nutritional Assessment-Short Form), and activities of daily living (according to the Barthel Index) were assessed. Sarcopenia was defined as skeletal muscle loss evaluated by both bioelectrical impedance and handgrip strength analyses. Of the 619 participants (mean age 83.0 ± 8.2 years), 417 (67.4%) and 87 (14.1%) had definitive and possible sarcopenia, respectively. The prevalence rates of cognitive impairment and stroke were significantly higher in patients with definitive sarcopenia and those with possible sarcopenia than in those without sarcopenia (cognitive impairment 54.4%, 70.1% and 20.9%, respectively, P < 0.001; stroke 31.2%, 48.3% and 19.1%, respectively, P < 0.001). Multivariate logistic regression analysis showed that cognitive impairment was independently associated with sarcopenia after adjusting for age, sex, the Mini-Nutritional Assessment-Short Form score, Barthel Index and primary disease (adjusted odds ratio 1.98, 95% confidence interval 1.06-3.71; P = 0.032). Sarcopenia might be highly prevalent among hospitalized older adults. Furthermore, cognitive impairment might be an independent explanatory variable of sarcopenia. Therefore, further studies on sarcopenia in patients with cognitive impairment are warranted. Geriatr Gerontol Int 2017; 17: 1048-1056.

Sarcopenia prevalence and factors associated with sarcopenia in older people living in a nursing home in Ankara Turkey.

Sarcopenia is prevalent in older people, and is related to survival and disability. There are no data on sarcopenia evaluated according to European Working Group on Sarcopenia in Older People criteria for nursing home residents in Turkey. We aimed to evaluate the prevalence of sarcopenia according to European Working Group on Sarcopenia in Older People criteria and associated factors with sarcopenia among nursing home residents in Turkey. The study cohort consisted of individuals aged over 65 years and living in the Seyranbağları Nursing Home and Rehabilitation Center in Ankara, Turkey. Besides demographic and medical data, Mini-Mental State Examination, activities of daily living, Mini-Nutritional Assessment, body mass index, calf circumference, gait speed and handgrip strength were also investigated. Muscle mass was evaluated by bioelectrical impedance analysis. Sarcopenia was diagnosed according to European Working Group on Sarcopenia in Older People criteria. A total of 141 older individuals were evaluated. Sarcopenia was found in 29% (n = 41) of the participants. Participants with sarcopenia were older and had low scores for activities of daily living, low body mass index, greater cognitive dysfunction, high malnutrition risk and low calf circumference. Body mass index and calf circumference were found to be associated with sarcopenia in multivariate logistic regression analysis. Almost one-third of older nursing home residents were diagnosed with sarcopenia according to European Working Group on Sarcopenia in Older People criteria in this study in Turkey. Calf circumference and body mass index were associated with increased risk of sarcopenia among nursing home residents. This is the first study evaluating sarcopenia using European Working Group on Sarcopenia in Older People criteria in Turkey. Geriatr Gerontol Int 2016; 16: 903-910.
