[Assessment of body fat in physically active young people: anthropometry vs bioimpedance]. / Valoración de la grasa corporal en jóvenes físicamente activos: antropometría vs bioimpedancia.

OBJECTIVE: To assess the level of agreement between the anthropometrical method and several bioimpedance (BIA) devices to estimate the fat mass in a group of physically active young people. SUBJECTS: 55 students of Physical Activity Sciences and Sports of the INEFC of Barcelona; 29 men (age: 24.7 +/- 4.7 years; BMI: 23.4 +/- 1.8) and 26 women (age: 22.9 +/- 3.5; BMI: 21.5 +/- 1.9). All of them voluntarily gave their informed consent. MATERIALS AND METHOD: Anthropometrical assessment was done according to the International Society for the Advancement Kinanthropometry (ISAK) protocol, the fat % was calculated by the Siri's equation and was compared with that obtained by 4 different BIA devices: Biospace Inbody 720, Tanita BC400, Tanita TBF-521, and Omron BF-300. To assess the level of agreement of the results, the interclass correlation coefficient and the Bland Aldman method were used. RESULTS: The estimated fat mass, in men, by the anthropometrical method was 7 +/- 2.2 kg. The results by the BIA systems were: 7.4 +/- 3 kg; 5.6 +/- 2.2 kg; 5.7 +/- 2.5 kg, and 7.4 +/- 3 kg for Biospace Inbody 720, Tanita BC400, Tanita TBF521, and Omron BF300, respectively. In women, the results were 10.4 +/- 2.7 kg of fat mass by means of the anthropometrical method and 10.3 +/- 2.9 kg, 11 +/- 3.3 kg, 11.5 +/- 3.0 kg, and 10 +/- 2.9 kg for Biospace Inbody 720, Tanita BC400, Tanita TBF521, and Omron BF300, respectively. CONCLUSIONS: In the male group, the level of agreement between anthropometrics and BIA devices was moderate-poor, whereas in women there was a good correlation between both techniques for estimating the body fat when the Biospace Inbody 720 and Tanita BC400 devices were used.

Objetivo: Analizar el nivel de concordancia entre el método antropométrico y diferentes aparatos de bioimpedancia (BIA) para la estimación de la masa grasa en un grupo de personas jóvenes y físicamente activas. Sujetos: Participaron 55 sujetos estudiantes de Ciencias de la Actividad Física y el Deporte del INEFC de Barcelona; 29 hombres (edad: 24,7 ± 4,7 años; IMC: 23,4 ± 1,8) y 26 mujeres (edad: 22,9 ± 3,5; IMC: 21,5 ± 1,9). Todos ellos otorgaron voluntariamente su consentimiento informado Material y métodos: La valoración antropométrica se realizó de acuerdo con el protocolo de la International Society for the Advancement Kinanthropometry (ISAK), el % graso fue calculado mediante la ecuación de Siri y se comparó con el obtenido por 4 aparatos BIA diferentes: Biospace Inbody 720, Tanita BC400, Tanita TBF-521 y Omron BF-300. Para valorar la concordancia de los resultados se utilizó el coeficiente de correlación intraclase y el método de Bland Aldman. Resultados: La masa grasa estimada, en hombres, mediante el método antropométrico fue de 7 ± 2,2 kg. Los resultados de los sistemas BIA fueron 7,4 ± 3 kg; 5,6 ± 2,2 kg; 5,7 ± 2,5 kg y 7,4 ± 3 kg para los aparatos Biospace Inbody 720, Tanita BC400, Tanita TBF521 y Omron BF300 respectivamente. En las mujeres los resultados fueron 10,4 ± 2,7 kg de masa grasa mediante el método antropométrico y 10,3 ± 2,9 kg; 11 ± 3,3 kg; 11,5 ± 3,0 kg; 10 ± 2,9 kg para los aparatos Biospace Inbody 720, Tanita BC400, Tanita TBF521 y Omron BF300 respectivamente. Conclusiones: En el grupo masculino la concordancia entre la antropometría y los aparatos BIA fue moderadabaja, en cambio en las mujeres se halló una buena concordancia entre las dos técnicas para la estimación de la grasa corporal cuando fueron utilizados los aparatos Biospace Inbody 720 y Tanita BC400 (AU)

Evaluation of anxiety in Parkinson's disease with some commonly used rating scales.

This study assessed the concurrent validity of the State-Trait Anxiety Inventory (STAI), the Hospital Anxiety and Depression Scale (HADS) and the Hamilton Anxiety Scale (Ham-A) for evaluating anxiety in a group of 46 Parkinson's disease (PD) patients. The magnitude of correlations between the scales was high (all p<0.01), indicating a good concurrent validity. The item-by item analysis indicated that the main characteristics of anxiety in PD patients were 'inability to relax', 'restlessness or inability to feel calm' and 'feeling tense'. The association between anxiety, as measured by the HADS-A, with demographic characteristics or clinical features of PD was not significant, supporting existing data suggesting that anxiety in PD is not closely correlated with the severity of motor symptoms or the degree of disability. The HADS-A may be the most appropriate scale for documenting patient-reported anxiety in depression.
