To measure the IQ and record dermatoglyphic patterns of children including intellectually disabled aged between 5 years and 11 years and to correlate them.
The present study was a cross-sectional study conducted in two private schools in the city corporation limits. A total of 300 children aged between 5 years and 11 years were equally allocated into three groups based on IQ using covariate adaptive randomization. IQ of the children was measured using Raven's Coloured Progressive Matrices. Bilateral palmar and finger prints were obtained on A4-size papers by ink method using rolling technique. Prints thus obtained were analyzed for dermatoglyphic variables using magnification lens and are read based on Cummins and Midlo classification for fingertip patterns and Bali and Chaube classification for palmar flexion creases. The data were entered and statistically analyzed. For statistical significance, a two-tailed probability value of less than 0.05 was taken as significant.
The current study suggests a relationship between different fingertip patterns of digits of I, II, III, and IV of left and right hand and also digit V of right hand with various levels of IQ.
Hence, dermatoglyphics can be considered as a preliminary noninvasive approach for the determination of IQ. Also, it plays an imperative role, especially in distinguishing genetic intellectual disabilities.

测量5至11岁儿童(包括智障儿童)的智商并记录其皮纹模式,并将二者进行关联分析。
本研究为横断面研究,在市辖区内的两所私立学校开展。采用协变量自适应随机化方法,将300名年龄在5至11岁的儿童按智商水平平均分为三组。使用瑞文彩色渐进矩阵测验测量儿童的智商。采用滚动技术,通过油墨法在A4尺寸的纸张上获取双侧手掌和指纹。使用放大镜对获取的指纹进行皮纹变量分析,并根据卡明斯和米德洛指尖模式分类以及巴厘和乔贝手掌褶纹分类进行读取。将数据录入并进行统计学分析。对于统计学显著性,双侧概率值小于0.05被视为具有显著性。
本研究表明,左右手的I、II、III和IV指以及右手的V指的不同指尖模式与不同水平的智商之间存在关联。
因此,皮纹学可被视为一种用于测定智商的初步非侵入性方法。此外,它尤其在区分遗传性智力障碍方面起着至关重要的作用。
