中文摘要：

指长比常用食指指长（2D）和环指指长（4D）的比值来表示，是产前雄性激素活动公认的生物学标记，具有性别、民族、种族和地域差异，对某些疾病的发生有一定的关系，可预测部分运动潜能。我们应用文献计量法，通过中外数据库，收集了近十年来国内外指长比的出版物，对其出版时间、专业领域分布、影响因子等进行了初步分析。研究表明，英国、美国、奥地利和德国等国研究较多，而我国起步较晚。当前，除对人进行指长比研究外，还对灵长类动物等进行了研究。这对深入研究健康的危险因素、预防疾病和研究人的行为、认知能力等都具有重要意义。指长比作为人体测量的指标仍是当前研究的热点，今后对指长比的人群差异，某些动物中的指长比研究及其在医学、体育科学、行为科学中的应用和其分子生物学基础还需要进一步深入地探讨。

英文摘要：

The digit length ratio of the second finger length to fourth finger length （2D： 41）） is a putative marker for prenatal androgen action, exists sexual, ethnic, racial, and geographic differences, is associated to the incidences of diseases and may pre-estimate physical capacity potential. This study reviewed publications on digit ratio over the past decade and analysed their publication time, professional distribution and impact factors. It indicated that the major publications came from British, United States, Austria and Germany and few from China. In addition in humans, digit ratio was studied in the primates. The digit ratio, as a anthropometry index, still is a hotpoint as it is important to estimate health risk factors, prevent some diseases, study human behavior and eognizence and so on. In the future, it needs to be probed thoroughly in differences of intergroups digit ratio, animas digit ratio, applications in medicine, sport science, behavior science and foundation molecular biology.
