本研究的目的是探讨在约旦的近亲结婚的世俗趋势和近亲婚姻的亚型，可能正在发生变化。在安曼的一个糖尿病诊所，共采访了1 032人。调查表提供了三代人的血缘状况和结婚日期的信息：受访者、他们的父母、配偶的父母及其子女。获得了5401对婚姻中的近亲关系数据。1950年以前缔结的婚姻被称为第一代，1950年至1979年缔结的婚姻被称为第二代，1980年以后缔结的婚姻被称为第三代。对于第一代、第二代和第三代，表亲婚姻分别占所有婚姻的20.2%、28.5%和19.5%，而父系平行表亲婚姻的亚型分别占所有表亲婚姻的75.6%、60.3%和43.3%。与非血亲父母的后代相比，表亲父母的后代更倾向于与他们的亲戚结婚，表亲父母和非血亲父母的后代中的表亲婚姻分别占所有婚姻的25.3%和17.1%。第1、2、3代的平均近交系数分别为0.0135、0.02、0.0142。总之，在安曼的代表性人口中，与1950年至1979年期间缔结的婚姻相比，1980年之后缔结的婚姻的表兄弟结婚率显着下降，但与1950年之前缔结的婚姻相比则没有下降。在表亲婚姻中，父系平行表亲的比例从一代到下一代稳步下降。
The objective of this study was to explore the secular trend in consanguinity in Jordan and the subtypes of consanguineous marriages that may be undergoing a change. A total of 1032 individuals attending a diabetic clinic in Amman were interviewed. The questionnaire provided information on consanguinity status and date of marriage among three generations: the persons interviewed, their parents, parents of their spouses and their offspring. Data on consanguinity status among 5401 marriages was obtained. Generations were named generation 1 for marriages contracted before 1950, generation 2 for marriages contracted between 1950 and 1979, and generation 3 for marriages contracted after 1980. For generations 1, 2, and 3, first-cousin marriages constituted 20.2, 28.5 and 19.5% of all marriages, respectively, while the subtype of paternal parallel first-cousin marriages constituted 75.6, 60.3 and 43.3% of all first-cousin marriages, respectively. The offspring of first-cousin parents were significantly more prone to marry their relatives than the offspring of non-consanguineous parents, with rates of first-cousin marriages among offspring of first-cousin parents and non-related parents constituting 25.3 and 17.1% of all marriages, respectively. For generations 1, 2 and 3, the average coefficient of inbreeding was 0.0135, 0.02 and 0.0142, respectively. In conclusion, first-cousin marriage rate among a representative population from Amman showed a significant decline among marriages contracted after 1980 compared to marriages contracted between 1950 and 1979, but not to marriages contracted before 1950. The proportion of paternal parallel first cousins among first-cousin marriages showed a steady decline from one generation to the next.
