Parity indicators in human skeletal material are highly desirable yet elusive. In this study, the relationships of dorsal pits and pubic tubercle elongation to parity are investigated in a sample of 148 modern female sets of pubic bones with associated birth information. The elongation of the pubic tubercle shows no significant correlation with number of births, but instead is associated with the distance this feature is from the pubic symphysis (p < 0.01) and the size of the arcuate angle (p < 0.05). Dorsal pits show a strong association with increasing numbers of births (p < 0.01), especially in younger women. However, in women over 50 years old, dorsal pitting is correlated with BMI (p < 0.05) and is not significantly correlated with number of births. While this study lends support to the correlation of dorsal pitting and parity, it currently does not reach the level of accuracy needed for forensic applications at the level of the individual.
人类骨骼材料中的生育指标非常值得研究，但却难以捉摸。在本研究中，对148套带有相关生育信息的现代女性耻骨样本，研究了背侧凹坑和耻骨结节延长与生育的关系。耻骨结节的延长与生育次数无显著相关性，而是与该特征距耻骨联合的距离相关（p < 0.01）以及弓状角的大小相关（p < 0.05）。背侧凹坑与生育次数增加有很强的相关性（p < 0.01），尤其是在年轻女性中。然而，在50岁以上的女性中，背侧凹坑与体重指数相关（p < 0.05），与生育次数无显著相关性。虽然本研究支持背侧凹坑与生育的相关性，但目前在个体层面上还未达到法医应用所需的准确程度。
