“…High BMI cut-off points, such as 30 kg/m 2 , are not appropriate to identify older obese adults due to their low sensitivity. Our findings together with the ones from another study 25 , showed that BMI values of 27 kg/m 2 and 25 kg/m 2 have higher sensitivity and are more accurate. This could be attributed to increases in body fat and reductions in muscle and bone masses that occur during ageing.…”

“…This could be attributed to increases in body fat and reductions in muscle and bone masses that occur during ageing. These changes are more pronounced in women 25 . Therefore, BMI and WC cut-off points should consider such differences.…”

“…Brazilian studies that evaluated both anthropometric parameters i.e. WC and BMI in older adults and their capacity to predict obesity 5,6,25 and cardiovascular risk 5 found a great variation of recommended cut-off points for BMI and WC with different sensitivity and specificity values 5 . The cut-off points proposed in the present study are similar to the ones suggested by Barbosa et al 25 having, overall, better sensitivity, specificity and accuracy.…”

The cut-off points proposed in the present study are similar to the ones suggested by Barbosa et al 25 having, overall, better sensitivity, specificity and accuracy. Differences found between international studies as well as between different regions within the same country, could be explained by the differences in outcomes used, analytical approach, presentation of the findings and heterogeneity of each population.…”

Resumo O objetivo deste estudo foi analisar a validade e a acurácia do Índice de Massa Corporal (IMC) e da Circunferência da Cintura (CC) na avaliação de obesidade avaliada pelo excesso de gordura corporal (GC) e propor pontos de corte mais adequados para idosos. Os pontos propostos da literatura IMC (25,27 ou 30 kg/m2) e CC (≥ 102 cm-homens e ≥ 88 cm-mulheres ou ≥ 90 cm-homens e ≥ 80 cm-mulheres) foram avaliados conforme densitometria corporal total. A elevada GC foi definida por percentil > 90. Dos 132 idosos, 60,6% eram mulheres de 60-91 anos. Os pontos de corte recomendados de IMC ≥ 25 e ≥ 27kg/m2 apresentaram desempenhos similares, sendo que o IMC ≥ 30kg/m2 apresentou alta especificidade e baixa sensibilidade no sexo masculino e melhor desempenho para GC nas mulheres. Os pontos de corte convencionais de CC não apresentaram boa sensibilidade/especificidade. Foram propostos novos pontos de corte para IMC (masculino-25 kg/m2; feminino-26,6 kg/m2) e CC (masculino-98,8 cm; feminino-77,8 cm). Estes valores demonstraram sensibilidade e especificidade > 74% e acurácia > 76%. As áreas sob a curva foram > 0,86. O presente estudo propõe a utilização de pontos de corte mais acurados para diagnóstico de obesidade/GC em idosos, sendo para homens IMC 25kg/m2 e CC de 98,8cm e para mulheres IMC de 26,6kg/m2 e CC de 77,8cm, com melhores níveis de sensibilidade e especificidade.

“…In patients with CKD, there are also a group of regressors with positive eGFR slopes not readily explained by measurement variations [ 11 ]. In this study, we showed that lower BMI and higher waist circumference were associated with a higher probability of biochemical eGFR increase in these older adults ( Table 3 ); indeed, lower BMI might be a surrogate for lower lean body mass while increasing waist circumference could indirectly suggest obesity [ 36 ]. The association between serum leukocyte counts and a higher probability of biochemical eGFR increase could also be explained by the presence of malnutrition-inflammation-cachexia syndrome in older adults, as shown by others [ 37 ].…”

Longitudinal changes of renal function help inform patients’ clinical courses and improve risk stratification. Rare studies address risk factors predicting changes in estimated glomerular filtration rate (eGFR) over time in older adults, particularly of Chinese ethnicity. We identified prospectively enrolled community-dwelling older adults (≥65 years) receiving annual health examinations between 2005 and 2015 with serum creatinine available continuously in a single institute, and used linear regression to derive individual’s annual eGFR changes, followed by multivariate logistic regression analyses to identify features associated with different eGFR change patterns. Among 500 elderly (71.3 ± 4.2 years), their mean annual eGFR changes were 0.84 ± 1.67 mL/min/1.73 m2/year, with 136 (27.2%) and 238 (47.6%) classified as having downward (annual eGFR change <0 mL/min/1.73 m2/year) and upward eGFR (≥1 mL/min/1.73 m2/year) trajectories, respectively. Multivariate logistic regression showed that higher age (odds ratio (OR) 1.08), worse renal function (OR 13.2), and more severe proteinuria (OR 9.86) or hematuria (OR 3.39) were predictive of a declining eGFR while greater waist circumference (OR 1.06) and higher leukocyte counts (OR 1.21) were predictive of an uprising 10-year eGFR. These findings elucidate important features associated with geriatric renal function variations, which are expected to improve their renal care.

Background: The incidence of elderly people experiencing falls is currently increasing, which results in serious medical issues, such as fear of falling, limited physical activity, disability, and bone fractures, especially hip fractures. This study aimed to investigate balancing ability using a multi-directional reach test (MDRT) in older adults with and without diabetes mellitus. Methods: 72 older adults with and without diabetes mellitus were recruited, and divided into two groups, including older adults without diabetes mellitus (n= 36) and older adults with diabetes mellitus (n= 36). All subjects completed all directions of the MDRT. Results: There were no significant differences in MDRT scores in all directions between the two groups (p>0.05). Both groups achieved the highest MDRT scores in the forward direction. In contrast, the two groups had the lowest scores of MDRT in a backward direction. Furthermore, older adults with diabetes mellitus had lower MDRT scores in all directions than older adults without diabetes mellitus. Conclusion: The current study indicated that MDRT could be used to investigate the ability of balance in individuals with diabetes mellitus.
