摘要: 作者在进行福建省畲族人口健康素质抽样调查中,对畲族的近亲结婚率、平均近交系数、近亲结婚类型、近亲结婚的有害遗传效应以及异族通婚进行研究。1994年4月至5月,在福建省的福安市穆阳乡、漳浦县赤岭乡和上杭县官庄乡,调查畲族婚姻6335对,其中近亲结婚54对。一级表亲占近亲结婚的92.58%。近亲结婚率0.85%,平均近交系数5.72×10,异族通婚率41.88%。近亲结婚率和平均近交系数与国内报道的31个民族比较,分别在第28位和第26位。异族通婚率与国内报道的18个民族比较,居首位。1950年以后,近亲结婚率有上升趋势,异族通婚率呈下降趋势。近亲结婚所生的0—14岁子女遗传病患病率显著高于非近亲结婚组。

Abstract: A survey on the consanguineous marriage of ` She’ ethnic group w as carried out in three districts ( xiangs) of Fujian Province. The total number of marriages studied w as 6335, among them there were 54 consanguineous marriages, with 92. 5% taking place between the first cousins o n maternal side. The percentage o f consanguineous marriage and average inbreeding coefficient w ere 0. 85% and 5. 72× 10- 4 respectively. The percentage o f mix ed marriage w as 41. 81% . The rate o f hereditary diseases among the children ( 0— 14 y ea rs) of consanguineous marriages was significantly higher than that of marriages between nonrelatives.

Key words: Consanguineous marriage, Inbreeding coefficient, Mixed marriage
