The bones of the human pelvis are used in sexual diagnosis generating a high level of accuracy for this type of identification. Morphological and/or morphometric methods are used in the identification of sex. Sexual dimorphism may be affected by ethnic differences in the population. One of the methods for determining sex using hip bone is the 'Diagnose Sexuelle Probabiliste (DSP)' or Probabilistic Sexual Diagnosis (DSP) method. The method presents a new version (Probabilistic Sexual Diagnosis v.2-DSP2) more advisable to be used because it has a more up-to-date database. The objective of this study is to investigate the applicability of the DSP2 method in a population in the Northeast region of Brazil. We used 128 hip bones, 50 female and 78 males, aged between 17 and 101 years, belonging to the Laboratory of Human Identification and Forensic Osteology of the University Federal Government of Pernambuco. The research was conducted between 2019 and 2020 and approved by the Research Ethics Committee of the Federal University of Pernambuco no. 43228015.0.0000.5208. The probability equal to or greater than 0.95 was used as the limit for the determination of sex, and the results were compared with the actual sex of each bone. In the Brazilian collection study, it was observed that the percentage of sex estimation provided by the DSP2 tool using all reference samples was 71.09%, and accuracy was 64.06%. In the analysis of the gender estimate, 82.0% and 78% were obtained for females and males, respectively. Regarding accuracy, it was 64.10% and 55.13% for females and males, respectively. In the contemporary osteological collection of the Northeast region of Brazil, which presents immigrant peoples, we obtained a high index of assertiveness in the DSP2 method. The study concluded that the DSP2 method is important for determining the sex of human skeletons in a miscegenated population.
人类骨盆的骨骼用于进行性别的诊断，为这种识别类型提供了高度的准确性。在识别性别时，使用形态学和/或形态计量学方法。性二态性可能会受到人口中种族差异的影响。使用髋骨确定性别的方法之一是“性概率诊断（DSP）”或概率性性诊断（DSP）方法。该方法提出了一个新版本（概率性性诊断 v.2-DSP2），更适合使用，因为它具有更新的数据库。本研究的目的是调查 DSP2 方法在巴西东北部人口中的适用性。我们使用了 128 块髋骨，50 块女性和 78 块男性，年龄在 17 至 101 岁之间，来自伯南布哥联邦大学人类识别和法医骨骼学实验室。该研究于 2019 年至 2020 年进行，并获得了伯南布哥联邦大学伦理委员会的批准，编号为 43228015.0.0000.5208。将概率等于或大于 0.95 用作确定性别的界限，并将结果与每个骨骼的实际性别进行比较。在巴西的研究中，观察到使用所有参考样本，DSP2 工具提供的性别估计百分比为 71.09%，准确性为 64.06%。在性别估计分析中，女性和男性分别获得了 82.0%和 78%的结果。至于准确性，女性和男性分别为 64.10%和 55.13%。在巴西东北部具有移民人口的当代骨骼学收藏中，我们获得了 DSP2 方法的高可信度。研究得出结论，DSP2 方法对于确定混血人群中人类骨骼的性别非常重要。
