Published evidence has shown that troncoconical cuffs improve blood pressure measurement accuracy in subjects with obesity. However, the exact shape of these cuffs according to arm size is unknown. The aim of the present study was to investigate the anthropometric characteristics of the arm in a large population in order to identify the appropriate shape of the cuff for each arm.
The anthropometric characteristics were assessed in 729 adults with middle arm circumference ranging from 16 to 55 cm. Subjects were divided into classes of arm size and the upper-arm slant angle of the truncated cone was calculated.
In the whole sample, the conical shape of the arm progressively increased with increasing arm circumference (r = 0.61, P < 0.0001). Independent predictors of the conical shape were arm circumference (P < 0.0001) and length (negative relationship, P < 0.0001), and female sex (P = 0.048). Women had a slightly more pronounced conical shape of the arm (P = 0.007) than men. However, the decrease in the slant angle across the arm-size classes showed a similar trend in men and women, and in a 2-way analysis of variance there was no interactive effect between arm size and sex on the conical shape of the arm (P = 0.11). On the basis of the slant angle calculated in each arm-size class, we provide dimensions for bladders that would appropriately fit the arm within a given circumference range.
To properly fit the upper arm in patients with obesity cuffs should have a troncoconical shape. This study provides reference data according to arm size.
已有研究表明，锥形袖口可提高肥胖人群的血压测量准确性。然而，目前尚不清楚根据手臂大小确定袖口具体形状的方法。本研究旨在调查大量人群的手臂人体测量特征，以确定适合每个手臂的袖口形状。
对 729 名臂周 16-55cm 的成年人进行人体测量特征评估。将受试者分为手臂尺寸类别，并计算截顶圆锥的上臂倾斜角。
在整个样本中，手臂的锥形形状随臂周的增加而逐渐增加（r=0.61，P<0.0001）。锥形形状的独立预测因子为臂周（P<0.0001）和长度（负相关，P<0.0001），以及性别（P=0.048）。女性手臂的锥形形状稍明显（P=0.007）。然而，臂围类别之间倾斜角的减小显示出男女相似的趋势，在两因素方差分析中，臂围和性别对手臂锥形形状没有交互作用（P=0.11）。根据每个臂围类别计算的倾斜角，我们为适合给定臂围范围内手臂的囊体提供了尺寸。
为了使肥胖患者的上臂得到适当贴合，袖口应具有截顶圆锥形。本研究根据手臂大小提供了参考数据。
