A sarcopenia screening test predicts mortality in hospitalized older adults.

ABSTRACT: The aim of this study is to investigate the validation of a sarcopenia screening test (Ishii's formula) for predicting long-term mortality among older adult inpatients. A prospective, observational study was conducted in acute geriatric wards at three hospitals in western China. Sarcopenia was estimated using Ishii's formula. Survival status was assessed at 12, 24, and 36 months after the baseline investigation. Cox proportional-hazard models were applied to calculate the hazard ratio for mortality associated with sarcopenia. Three hundred and eighty participants (100 women) with a mean age of 80.2?±?7.1 years were included. According to Ishii's formula, 264 participants (69.5%) were sarcopenic. The prevalence of sarcopenia was similar in men and women (71.1% vs. 65.0%, respectively, P?=?0.258). Sixty-seven participants (17.6%) died during the 3-year follow-up period. The all-cause mortality was significantly higher in the sarcopenia group than in the non-sarcopenia group (20.1% vs. 12.1%, respectively, P?

Project description:BackgroundSarcopenia is associated with adverse outcomes among older adults with cancer; however, no easily applied sarcopenia measure exists for use in clinical practice. The use of SARC-F, a 5-item self-reported sarcopenia screening questionnaire, among older adults with cancer remains to be investigated.MethodsOlder adults (aged ≥60 years) with cancer enrolled in the University of Alabama Cancer and Aging Resilience Evaluation Registry were identified. Patients completed the SARC-F questionnaire (with scores ≥4 considered positive for sarcopenia). The authors assessed for differences in geriatric assessment domain impairments, health-related quality of life, and health care utilization between those with and without sarcopenia using multivariate regression, then assessed the association of sarcopenia with survival using Kaplan-Meier methods and a Cox regression model, adjusting for covariates.ResultsIn total, 256 older adults were identified. The median age was 69 years, 59% of participants were men, and 75% were White. The median SARC-F score was 2 (interquartile range, 0-4), and 33% of participants screened positive. Those with sarcopenia had higher odds of having multiple impairments, including impaired instrumental activities of daily living (adjusted odds ratio [aOR], 18.1; 95% CI, 7.5-43.8) and frailty (aOR, 43.5; 95% CI, 17.7-106.8) as well as reduced physical and mental health-related quality of life (β coefficient, -13.6 and -11.5, respectively) and increased emergency room visits (aOR, 2.4; 95% CI, 1.3-4.7). Furthermore, sarcopenia was independently associated with inferior overall survival (adjusted hazard ratio, 2.98; 95% CI, 1.1-8.3; P = .04).ConclusionsOne-third of older adults with cancer in this cohort screened positive for sarcopenia using the SARC-F screening questionnaire, and these positive scores are associated with geriatric assessment domain impairments, reduced health-related quality of life, increased emergency room visits, and inferior overall survival.

Project description:ObjectiveHyperhomocysteinemia (HHcy) is considered to increase the risk of sarcopenia (S) and remains controversial. In this study, we aimed to investigate the prevalence of S among older Chinese adults and explore whether homocysteine (Hcy) was independently associated with S.MethodsThis cross-sectional study was performed among older adults hospitalized in the Geriatric Hospital of Nanjing Medical University between June 2017 and December 2021. We measured all participants' serum Hcy levels, hand grip strength, gait speed and appendicular skeletal muscle index(ASMI) using bioelectrical impedance analysis (BIA). S was defined based on the criteria of the Asian Working Group for Sarcopenia 2 (AWGS2), which included muscle mass (ASMI< 7.0 kg/m2 for men and ASMI< 5.7 kg/m2 for women by BIA) and low muscle strength (handgrip strength < 28 kg for men and < 18 kg for women), and/or gait speed < 1.0 m/s. HHcy defined as Hcy ≥10 μmol/L. The strength of the association between Hcy and the risk of S was analyzed by multivariate logistic regression using three models that adjusted for possible confounding variables to calculate the odds ratios (ORs) and 95% confidence intervals (CIs).ResultsAmong the 441 subjects, 161 (36.5%) were diagnosed with S, and 343 (77.8%) were diagnosed with HHcy. A significant association was detected between S and serum Hcy per 1-μmol/L increase after adjustment for age, gender, education, smoking, body mass index (BMI), Mini Nutritional Assessment Short Form (MNA-SF), alanine aminotransferase (ALT), C-reactive protein (CRP), hemoglobin (Hb), albumin (ALB), diabetes, kidney disease, and statin use (OR = 1.07, 95% CI = 1.03-1.12, P = 0.002). The OR for S in the HHcy group (≥10 μmol/L) was nearly 5-fold that in the normal Hcy group (OR 4.96, 95% CI 2.67-9.24, P < 0.001). In a gender-based subgroup analysis that adjusted for age, education, smoking, BMI, MNA-SF, ALT, CRP, Hb, and ALB, female subjects with HHcy had an increased risk of S (OR 10.35, 95% CI 2.84-37.68, P < 0.001).ConclusionsOur results demonstrated that elevated Hcy levels have an independent association with S in older adults. This suggests that the downward adjustment of HHcy (cutoff value < 10 μmol/l) might decrease the risk of S.
