The purpose of this study was to evaluate gender-wise diversity of digital dermatoglyphic traits in a sample of Sinhalese people in Sri Lanka.
Four thousand and thirty-four digital prints of 434 Sinhalese individuals (217 males and 217 females) were examined for their digital dermatoglyphic pattern distribution. The mean age for the entire group was 23.66 years (standard deviation = 4.93 years). The loop pattern is observed more frequently (n = 2,592, 59.72%) compared to whorl (n = 1,542, 35.53%) and arch (n = 206, 4.75%) in the Sinhalese population. Females (n = 1,274, 58.71%) have a more ulnar loop pattern than males (n = 1,231, 56.73%). The plain whorl pattern is observed more frequently in males (n = 560, 25.81%) compared to females (n = 514, 23.69%).The double loop pattern is observed more frequently on the right and left thumb (digit 1) of both males and females. Pattern intensity index, Dankmeijer index and Furuhata index are higher in males.
Ulnar loop is the most frequently occurring digital dermatoglyphic pattern among the Sinhalese. All pattern indices are higher in males. To some extent, dermatoglyphic patterns of Sinhalese are similar to North Indians and other Caucasoid populations. Further studies with larger sample sizes are recommended to confirm our findings.
本研究旨在评估斯里兰卡僧伽罗人群样本中数字皮纹特征的性别多样性。
对 434 名僧伽罗个体（217 名男性和 217 名女性）的 4034 个数字指纹进行了检查，以评估其数字皮纹模式分布。整个群体的平均年龄为 23.66 岁（标准差=4.93 岁）。在僧伽罗人群中，环型（n=2592，占 59.72%）比涡型（n=1542，占 35.53%）和弓型（n=206，占 4.75%）更为常见。女性（n=1274，占 58.71%）的尺侧环型多于男性（n=1231，占 56.73%）。男性（n=560，占 25.81%）的单纯涡型比女性（n=514，占 23.69%）更为常见。双环型在男性和女性的右手和左手拇指（第 1 指）更为常见。男性的模式强度指数、丹克迈耶指数和古贺指数较高。
在僧伽罗人中，尺侧环型是最常见的数字皮纹类型。所有的模式指数在男性中都较高。在某种程度上，僧伽罗人的皮纹模式与北印度人和其他白种人群相似。建议进行更大样本量的进一步研究，以证实我们的发现。
