Some adult human females show bone resorption (pitting) at the dorsal aspect of the pubis and preauricular area of the ilium. The etiology of pelvic bone resorption is attributed alternatively to reproduction and to pelvic anatomy. While most researchers infer that pelvic pitting is related to reproduction, only a few studies are based on women of known parity. Degree of pubic resorption is directly associated with both parity (Suchey et al.: Am. J. Phys. Anthropol. 51:517-539, 1979; Bergfelder and Hermann: J. Hum. Evol. 9:611-613, 1980) and age (Suchey et al.: Am. J. Phys. Anthropol. 51:517-539, 1979). The relationship between parity and degree of resorption of the preauricular area is equivocal, found to be significant by Dunlap (A Study of the Preauricular Sulcus in a Cadaver Population, Ph.D. dissertation, East Lansing, Michigan State University, 1981) but not by Spring et al. (Am. J. Phys. Anthropol. 79:247-252, 1989); both studies report that age is not associated with resorption of the preauricular area. Other mammals evidence public resorption, but the morphology of the preauricular area is less well known. This study addresses the issue on the etiology of pelvic bone resorption using a sample of Macaca mulatta (the free-ranging population from Cayo Santiago) for which parity and age at death are known for all specimens. The following results are reported. Resorption of the pubis is common among females but infrequent among males. Contrary to Rawlins (Am. J. Phys. Anthropol. 42:477-488, 1975), the degree of pubic resorption in female macaques is significantly related to both parity and age at death.(ABSTRACT TRUNCATED AT 250 WORDS)

一些成年女性在耻骨的背侧和the骨的耳前区表现出骨吸收 (点蚀)。骨盆骨吸收的病因可归因于生殖和骨盆解剖。虽然大多数研究人员推断骨盆凹陷与生殖有关,但只有少数研究是基于已知均等的女性。耻骨吸收的程度与宇称 (Suchey等人: Am. J. Phys. Anthropol. 51:517-539,1979; Bergfelder和Hermann: J. Hum. Evol. 9:611-613,1980) 和年龄 (Suchey等人: 上午。J. Phys. Anthropol. 51:517-539,1979)。地称与耳前区吸收程度之间的关系是模棱两可的,由Dunlap发现是显着的 (对尸体人群中的耳前沟的研究,博士学位论文,密歇根州立大学东兰辛,1981),但不是Spring等人 (Am. J. Phys. Anthropol. 79:247-252,1989); 两项研究均报告年龄与耳前区域的吸收无关。其他哺乳动物证明公众吸收,但耳前区的形态鲜为人知。这项研究使用Macaca mulatta (来自Cayo Santiago的自由放养人群) 样本解决了骨盆骨吸收的病因学问题,所有标本都已知死亡年龄和死亡年龄。报告了以下结果。耻骨的吸收在女性中很常见,但在男性中很少。与罗林斯相反 (Am. J. Phys. Anthropol. 42:477-488,1975),雌性猕猴的耻骨吸收程度与死亡时的同胎和年龄均显着相关。(摘要截短于250字)
