Diagnostic performance of calf circumference, SARC-F, and SARC-CalF for possible sarcopenia screening in Indonesia.

Asian working group for sarcopenia (AWGS) recently introduced "possible sarcopenia" diagnosis for early identification of sarcopenia in the primary healthcare. For initial screening, 3 modalities, i.e. calf circumference (CC) measurement, strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) questionnaire, and a combination of both (SARC-CalF), are recommended. However, no validation study has been done until now. Therefore, this study aims to evaluate the diagnostic performance of the recommended screening modalities using data from Indonesia. This cross-sectional study included subjects aged ≥ 60 years old who visited primary healthcare in Surabaya, Indonesia. The diagnosis of possible sarcopenia was confirmed with hand-grip strength and repeated chair stand test. Receiver operating characteristic curve analysis was used to evaluate the diagnostic performance. Among 266 subjects, 186 (70%) were diagnosed with possible sarcopenia. Using the recommended cut-off, the area under the curve, sensitivity, and specificity were 0.511, 48.39% and 53.75% for CC, 0.543, 8.60% and 100% for SARC-F, and 0.572, 19.35% and 95% for SACRC-CalF. Our findings indicate that the diagnostic performance of the recommended screening modalities is poor. Multicenter studies from different areas in Indonesia should be done to confirm these findings.

Sarcopenia and Frailty Profile in the Elderly Community of Surabaya: A Descriptive Study.

BACKGROUND: sarcopenia and frailty cause immobility, disability, neuromuscular disorders, and homeostatic balance failure syndrome, characterized by gait and balance abnormalities in the elderly, and an increasing prevalence worldwide. This further contributes to the elevated incidence of falls and fractures, hospitalization, immobilization, and even mortality, hence, a national-level study was conducted on the prevalence rates of sarcopenia and frailty in the elderly. METHODS: this descriptive study used primary data of elderly people (n = 308) in Surabaya, Indonesia. Furthermore, the biopsychosocial data, weight loss, fatigue, and physical activity measurements were obtained through interviews, while handgrip strength, muscle mass, and physical performance (walking speed) were evaluated using instruments. RESULTS: the median age of the subjects was 63 years (60-100 years), and 230 (74.7%) were women. In addition the prevalence rate of sarcopenia was 41.8% (in 86 [27.9%] women), while the prevalence rate of frailty was 36.7% (in 16 [5.2%] men and 97 [31.5%] women). CONCLUSION: the prevalence of sarcopenia and frailty in the elderly is significantly high, thus, it is expected that this study results are used as a basis for subsequent research, especially to determine the sarcopenia cut-off, in accordance with Indonesian sociodemography.

Cut-off of anthropometry measurement and nutritional status among elderly outpatient in Indonesia: multi-centre study.

AIM: To obtain the cut-off value of anthropometric measurements and nutritional status of elderly in Indonesia. METHODS: A multicentre-cross sectional study was performed at 9 hospitals in Indonesia. The data collected comprises of samples characteristics, anthropometric measurements (weight, height, trisep, bisep, subscapular, suprailiac, and circumference of the hip, waist, arm, calf, and thigh), albumin value, MNA score and ADL Index of Barthel. RESULTS: A total of 702 subjects were collected. The average value of serum albumin is 4.28 g/dl, with 98% subjects had normal serum albumin (> 3.5 g/dl). The mean MNA score and BMI was 23.07 and 22.54 respectively. Most of subjects (56.70%) had risk of malnutrition based on MNA score, and 45.01% had normal nutritional status based on body mass index. Average value of several anthropometric measures (weight, stature, and body mass index; sub-scapular and supra-iliac skinfolds; thigh, calf, mid-arm, and waist circumferences) in various age groups in both groups of women and men were obtained. Cut-off values of various anthropometric indicators were also analyzed in this study with MNA as a gold standard. CONCLUSION: This study showed age related anthropometric measurement differences in both men and women aged 60 years and older.
