Aim
The SARC‐F is a useful clinical index for sarcopenia screening; however, this measure has low sensitivity. Furthermore, this tool has never been validated on community‐dwelling older Japanese adults. The goal of the present study was to validate a Japanese version of the SARC‐F and confirm its suitability for Japanese samples.
Methods
Participants were 734 community‐dwelling older adults in the Itabashi Ward, Japan. Bioimpedance measures, walking speed, grip strength and instrumental activities of daily living (IADL) were measured. Sarcopenia was defined using the European Working Group on Sarcopenia in Older People, the Asian Working Group for Sarcopenia criteria and Japanese‐adjusted Asian Working Group for Sarcopenia. SARC‐F receiver operating characteristic curves for each sarcopenia measure were used to evaluate diagnostic accuracy. Physical functioning, IADL and sarcopenia screening tools were compared with the SARC‐F.
Results
A total of nine men (3.1%) and 15 women (3.4%) were classified into a SARC‐F sarcopenia group. The sarcopenia group had lower physical functioning and Mini Sarcopenia Risk Assessment scores and higher frailty status than the control group. The Cronbach's alpha for the SARC‐F was 0.610, suggesting insufficient internal consistency. SARC‐F scores were related to physical functioning, IADL, and Mini Sarcopenia Risk Assessment scores. Receiver operating characteristic analyses of the SARC‐F based on each criterion showed low sensitivity, but high specificity.
Conclusions
The Japanese version of the SARC‐F appears to be a useful index for reflecting physical functioning and IADL. However, it is necessary to further determine whether this tool is useful for detecting sarcopenia among community‐dwelling older adults. Geriatr Gerontol Int 2019; 19: 1172–1178.

“…Questionnaires are proposed as an initial screening test to confirm clinical suspicions or avoid further investigation. The Mini Sarcopenia Risk Assessment (MSRA) questionnaire investigates anamnestic and nutritional characteristics related to the risk of sarcopenia (17); SARC-F is an easy-toapply questionnaire that asks daily-life questions, seeking answers based on the patient's perception of his or her limitations in strength, walking facility, capacity to rise from a chair, stair-climbing and any associated experiences with falls; a score ≥4 is predictive of sarcopenia and a poor outcome (18). Both questionnaires have demonstrated similar diagnostic accuracy, although SARC-F has offered better specificity.…”
Objective
This paper reviews the main mechanisms, diagnostic criteria, treatment options and available data on sarcopenia in endocrine and non-endocrine disorders. The literature notes the presence of sarcopenia as a comorbid condition or a complication of another clinical situation and not a disease that only affects elderly patients.
Method
We performed a literature review, focusing on the following: mechanisms related to sarcopenia in elderly patients, and sarcopenia as it presents in the context of chronic and endocrine diseases; diagnostic tools and methods; aspects of sarcopenia and treatment options specific to chronic diseases and endocrine disorders respectively.
Results
Sarcopenia in chronic and endocrine disorders shares many mechanisms with sarcopenia affecting elderly patients, but certain diseases can have a predominant aspect that leads to sarcopenia. The prevalence of sarcopenia varies, depending on different diagnostic criteria, from around 12 to 60% in chronic illnesses and 15 to 90% in endocrine disorders. The interplay between sarcopenia, chronic diseases and elderly patients requires further study, to clarify the impact of each, in terms of prognosis and mortality.
Conclusion
Awareness of the presentation of sarcopenia in the context of other diseases and ages (and not just the elderly) is fundamental to ensure that preventive measures can be deployed.
