Calf Circumference is more effective than body mass index in predicting emerging care need of older adults results of a national cohort study
Clinical Nutrition, 2016Co-Authors: Alan C Tsai, Jiunyi WangAbstract:Summary Background & aims The usefulness of body mass index (BMI) and Calf Circumference (CC) for predicting emerging care-need of older adults has not been carefully evaluated. We attempted to compare the abilities of these two anthropometrics in predicting emerging care-need in older adults. Methods We analyzed the 1999 (baseline) and 2003 (end-point) datasets of the Taiwan Longitudinal Survey on Aging. Participants were 2521 ≥ 65-year old adults without care at baseline. To derive proper cut-offs of BMI and CC, we first drew a plot to show the relationship between the risk of care-need and the cumulative distribution of BMI or CC. We then divided the risk into three levels and calculated the corresponding percentiles of BMI and CC. Multivariable logistic regression was used to build up predictive models. Akaike Information Criterion (AIC) and net reclassification improvement (NRI) were performed to compare the models as well as the predictive abilities of BMI and CC. Results After controlled other independent variables, CC was significantly associated with emerging care-need in the subsequent 4 years, but BMI was not. The AIC value of the model with CC (1956.3) was remarkably lower than BMI (1968.7). The NRI was 4.8% (p = 0.007) which quantified the improvement of the model with inclusion of CC instead of BMI to predict emerging care-need. Conclusions All indices we performed suggest that CC has better ability to predict emerging care-need in older Taiwanese compared to BMI. The potential application of anthropometric indicators, especially CC, for predicting emerging care-need deserves further investigation.

short form mini nutritional assessment with either bmi or Calf Circumference is effective in rating the nutritional status of elderly taiwanese results of a national cohort study
British Journal of Nutrition, 2013Co-Authors: Alan C Tsai, Tsuilan Chang, Jiunyi WangAbstract:AbstractThe present study was aimed to validate two normalised short-form (SF) Mini-Nutritional Assessments (MNA) that contained either BMI(Taiwan version 1, T1) or Calf Circumference (CC; Taiwan version 2, T2) for rating the nutritional status of elderly Taiwanese. Both versionsadopted Taiwanese anthropometric cut-offs, but T2 further had the BMI item replaced by CC. We compared the ability of the two SF inrating the nutritional status of 2674 elderly Taiwanese in the 1999 ‘Taiwan Longitudinal Survey on Aging’ with their respective full versions.We evaluated the agreement between the SF and full scales with weighted kand performed Cox regression analysis for the follow-up4-year mortality according to nutritional status rated at baseline. The results showed that the agreements between the respective SF andthe full MNA were good (weighted k: 0·679 for T1 and 0·667 for T2). Both SF performed well in predicting follow-up 4-year mortalityrelative to the full MNA. In conclusion, MNA-T1-SF and -T2-SF have good consistency with the full MNA and have quite comparableabilities in rating the nutritional status of elderly Taiwanese. Both SF versions appear appropriate for functioning as stand-alone unitsfor rating the nutritional status of the elderly in community-living settings or the general population.Key words: Mini-Nutritional Assessment: Nutritional assessment: Malnutrition: Elderly: Taiwan

the effectiveness of bmi Calf Circumference and mid arm Circumference in predicting subsequent mortality risk in elderly taiwanese
British Journal of Nutrition, 2011Co-Authors: Alan C Tsai, Tsuilan ChangAbstract:AbstractBMI, mid-arm Circumference (MAC) and Calf Circumference (CC) are anthropometric indicators often included in geriatric health measure-ment scales. However, their relative effectiveness in predicting long-term mortality risk has not been extensively examined. The presentstudy aimed to evaluate the relative effectiveness of these anthropometrics in predicting long-term mortality risk in older adults.The study prospectively analysed the ability of these indicators in predicting 4-year follow-up mortality risk of a population-representativesample of 4191 men and women, 53 years of age or older in the ‘Survey of Health and Living Status of the Elderly in Taiwan’. Coxregression analyses were performed to evaluate the association of follow-up mortality risk with low (,21kg/m 2 ) or high ($27kg/m 2 )BMI, low MAC (,23·5/22cm for men/women) and low CC (,30/27cm) respectively, according to Taiwanese-specific cut-off points.Results showed that low CC and low MAC were more effective than low BMI in predicting follow-up mortality risk in 65–74-year-oldelderly. But low CC and low BMI were more effective than low MAC in $ 75-year-old elderly, and low BMI was more effective thanlow MAC or low CC in 53–64-year-old persons. High BMI was not effective in predicting mortality risk in any of these age ranges.These results suggest that in elderly adults, CC is more effective than BMI in predicting long-term mortality risk. Thus, more considerationto CC and MAC in designing geriatric health or nutritional measurement scales is recommended.Key words: BMI: Mid-arm Circumference: Calf Circumference: Mortality risk

population specific short form mini nutritional assessment with body mass index or Calf Circumference can predict risk of malnutrition in community living or institutionalized elderly people in taiwan
Journal of The American Dietetic Association, 2010Co-Authors: Alan C Tsai, Tsuilan Chang, Yichen Wang, Chiuying LiaoAbstract:Abstract A simple, reliable, noninvasive, and easy-to-use instrument is important for successful monitoring of emerging nutrition problems in elderly people. The objectives of this study were to determine whether adoption of population-specific body mass index (BMI) cutpoints would improve the predictive ability of the short-form Mini Nutritional Assessment (MNA) and whether Calf Circumference could be an acceptable alternative to BMI in the short-form MNA without compromising its predictive ability. Using convenience sampling, the study recruited 301 community-living, 109 care center–living, and 68 nursing home–living elderly people, 65 years or older, as subjects. Subjects were evaluated with the short-form MNA in three versions: (a) the original, (b) Taiwan version 1 (T1), that adopted population-specific BMI cutpoints, and (c) Taiwan version 2 (T2), which substituted Calf Circumference for BMI, and with the long-form MNA-T2 as a reference. The ability of the short forms to predict the long-form MNA-T2 was evaluated with binary classification and analysis of receiver operating characteristic curves. Results were analyzed with an SPSS for Windows 12.0 software package (version 12.0.1C, 2000, SPSS Inc, Chicago, IL). Results showed that adoption of population-specific anthropometric BMI cutpoints improved the predictive ability of the short-form MNA, whereas replacement of BMI with Calf Circumference further improved the predictive ability of the scale (kappa values of the binary classification tests were 0.596, 0.742, and 0.843 for community-living; 0.560, 0.683, and 0.839 for care center–living; and 0.346, 0.454, and 0.522 for nursing home–living elderly for the original, T1, and T2 MNA short-form versions, respectively). These results suggest that modification of a measurement tool according to cultural or anthropometric features of the target population is necessary. The study also shows that Calf Circumference can be an acceptable alternative to BMI in the short-form MNA. Because measuring Calf Circumference is easier and less time-consuming then measuring BMI, the modified tool can make periodic nutritional screening an easier job and routine nutritional screening a more realistic goal in geriatric care.

Muscle function-dependent sarcopenia and cut-off values of possible predictors in community-dwelling Turkish elderly: Calf Circumference, midarm muscle Circumference and walking speed
European Journal of Clinical Nutrition, 2015Co-Authors: Sibel Akin, Salime Mucuk, Ahmet Ozturk, Mumtaz M Mazicioglu, şemsinur Gocer, Sibel Arguvanli, Elif Deniz şafakAbstract:Background/Objectives: The aim of this study was to determine the prevalence of muscle strength-based sarcopenia and to determine possible predictors. Subjects/Methods: This is a cross-sectional population-based study in the community-dwelling Turkish elderly. Anthropometric measurements, namely body height, weight, triceps skin fold (TSF), mid upper arm Circumference (MUAC), waist Circumference (WC) and Calf Circumference (CC), were noted. The midarm muscle Circumference (MAMC) was calculated by using MUAC and TSF measurement. Sarcopenia was assessed, adjusted for body mass index (BMI) and gender, according to muscle strength. Physical performance was determined by 4 m walking speed (WS; m/s). The receiver operating curve analysis was performed to determine cut-offs of CC, MAMC and 4 m WS. Results: A total of 879 elderly subjects, 50.1% of whom were female, were recruited. The mean handgrip strength (HGS) and s.d. was 24.2 (8.8) kg [17.9 (4.8) female, 30.6 (7.1) male]. The muscle function-dependent sarcopenia was 63.4% (female 73.5%, male 53.2%). The muscle mass-dependent sarcopenia for CC (
