Abstract

Harris lines (HLs) are radiographically visible transverse lines of thickened bone that develop from temporary growth cessation during early life. Often attributed to physiological stress during development, HLs are frequently observed in the long bones of adolescents and become less visible over time due to bone remodeling. In recent years, the validity of HL as a sign of stress has been called into question and the methods used in studying HL through X-ray analysis scrutinized. In this study, 80 individuals from the Middle Holocene Cis-Baikal region of Siberia, from the Early Neolithic (EN; 7560–6660 HPD cal. BP) and Late Neolithic (LN; 6060–4970 HPD cal. BP), were studied for the presence and severity of HL. Radiographic analysis employed both the traditional clinical anteroposterior (A–P) orientation and a potentially improved mediolateral (M–L) orientation. EN groups in the Cis-Baikal are known to have experienced higher levels than their LN counterparts; thus, if HL reflect stress experiences, we expected to see more HL in the EN population compared with the LN population. We also expected more visible HL in the M–L orientation due to the suggested improvement in capturing more lines compared with the A–P orientation. While the results support the use of M–L orientation during X-ray capture of HL, there was not a higher number of HL in the EN population as expected. Instead, no significant differences were found in HL severity between the EN and LN populations, and age-at-death resulted in a greater effect on HL counts regardless of mortuary site. The results from this study align not with known stress data from the Middle Holocene Cis-Baikal populations but rather with data pertaining to known growth patterns. We therefore advocate against the use of HL as a sign of physiological stress and instead suggest HL as a reflection of bone growth trajectory.

字里行间的解读:对西斯-贝加尔地区全新世中期觅食者哈里斯纹路的研究
哈里斯线(HLs)是一种在放射影像学上可见的横向骨增厚线,由生命早期的暂时性生长停止形成。HL 通常被认为是发育过程中的生理压力所致,经常在青少年的长骨中观察到,随着时间的推移,HL 会因骨骼重塑而变得不那么明显。近年来,HL 作为压力标志的有效性受到质疑,通过 X 射线分析研究 HL 的方法也受到审查。在这项研究中,研究人员对来自西伯利亚中全新世西斯-贝加尔地区(新石器时代早期(EN;7560-6660 HPD cal. BP)和新石器时代晚期(LN;6060-4970 HPD cal. BP)的 80 个个体进行了研究,以了解 HL 的存在和严重程度。放射学分析采用了传统的临床前胸(A-P)方向和经过改进的内外侧(M-L)方向。众所周知,Cis-Baikal 地区的 EN 族群比 LN 族群经历的压力更大;因此,如果 HL 反映了压力经历,我们预计 EN 族群中的 HL 会比 LN 族群中的更多。我们还预计,与 A-P 方向相比,M-L 方向在捕捉更多线条方面有所改进,因此 M-L 方向的 HL 更明显。虽然结果支持在 X 射线捕获 HL 时使用 M-L 方向,但 EN 群体中的 HL 数量并没有像预期的那样多。相反,EN人群和LN人群的HL严重程度没有明显差异,而死亡年龄对HL数量的影响更大,与停尸地点无关。这项研究的结果并不符合中全新世西斯-贝加尔人群的已知压力数据,而是与已知生长模式相关的数据相吻合。因此,我们不主张将 HL 作为生理压力的标志,而是建议将 HL 作为骨骼生长轨迹的反映。

期刊介绍: The aim of the International Journal of Osteoarchaeology is to provide a forum for the publication of papers dealing with all aspects of the study of human and animal bones from archaeological contexts. The journal will publish original papers dealing with human or animal bone research from any area of the world. It will also publish short papers which give important preliminary observations from work in progress and it will publish book reviews. All papers will be subject to peer review. The journal will be aimed principally towards all those with a professional interest in the study of human and animal bones. This includes archaeologists, anthropologists, human and animal bone specialists, palaeopathologists and medical historians.
