  • 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, 2016
    Co-Authors: Alan C Tsai, Jiunyi Wang

    Abstract:

    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, 2013
    Co-Authors: Alan C Tsai, Tsuilan Chang, Jiunyi Wang

    Abstract:

    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

  • agreement between body mass index Calf Circumference arm Circumference habitual energy intake and the mna in hospitalized elderly
    Journal of Nutrition Health & Aging, 2012
    Co-Authors: Vânia Aparecida Leandromerhi, Luiz Braga J De Aquino, Gonzaga Teixeira J De Camargo

    Abstract:

    Objectives
    This study aimed to assess the agreement between body mass index, Calf Circumference, arm Circumference, habitual energy intake and the mini nutritional assessment (MNA) and then assess the accuracy of these parameters in relation to the MNA.

  • 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, 2015
    Co-Authors: Sibel Akin, Salime Mucuk, Ahmet Ozturk, Mumtaz M Mazicioglu, şemsinur Gocer, Sibel Arguvanli, Elif Deniz şafak

    Abstract:

    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 (
