Although dietitians play an important role in the anthropometric assessment, reports on measurements made by these health professionals rarely include estimates of measurement error.
To estimate of intraobserver precision for three common anthropometric measurements made by dietitians.
Twenty six measurers performed measurements (upper mid-arm circumference, tricipital and bicipital skinfold) in two times a sample of ten volunteers. Four precision estimates were calculated: the technical error of measurement (TEM), the relative technical error of measurement (rTEM), the coefficient of reliability (R) and the coefficient of variation (CV).
For skinfold thickness, rTEM was smaller than 2.2; for circumference, rTEM was smaller than 0.6. The precision to measure skinfolds was lower than the precision to circumference. Anyway, for all measurements R showed a high degree of precision (R > 95).
Our results suggest that anthropometric parameters evaluated are sufficiently precise. However, periodical training is necessary to control and minimize the anthropometric measurement error.
尽管营养师在人体测量评估中发挥着重要作用，但关于这些健康专业人员所做测量的报告很少包括测量误差估计。
估计营养师进行的三种常见人体测量的观察者内精密度。
26名测量者对10名志愿者样本进行两次测量（上臂中部周长、三头肌和二头肌皮褶厚度）。计算了四个精密度估计值：测量技术误差（TEM）、相对测量技术误差（rTEM）、可靠性系数（R）和变异系数（CV）。
对于皮褶厚度，rTEM小于2.2；对于周长，rTEM小于0.6。测量皮褶的精密度低于测量周长的精密度。无论如何，对于所有测量，R均显示出高度精密度（R>95）。
我们的结果表明所评估的人体测量参数足够精确。然而，需要定期培训以控制和最小化人体测量误差。
