OBJECTIVES
The Osteological Paradox posits that skeletal lesions may differentially be interpreted as representing resilience or frailty. However, specific consideration of the etiologies and demographic distributions of individual skeletal indicators can inform the criteria on which to differentiate stress, frailty, and resilience. Adopting a life history approach and adaptive plasticity model, this study proposes a framework for the analysis and interpretation of a commonly reported skeletal lesion, cribra orbitalia, which considers the underlying mechanisms of the condition, the clinical and epidemiological literature relating to anemia and malnutrition, and the bioarcheological evidence.
MATERIALS AND METHODS
Data were extracted from the European (n = 33 populations) and American (n = 19 populations) modules of the Global History of Health Project. Kaplan-Meier and Cox regression analyses were applied, where time was the age-at-death, and the factor or covariate was presence or absence of cribra orbitalia.
RESULTS
Of 37 samples that produced significant results, 21 demonstrated a change in relationship when the subadults were excluded from analysis. When subadults were included, individuals with cribra orbitalia present had statistically significant lower survival time. With subadults excluded, the relationship either became nonsignificant or was reversed.
DISCUSSION
We demonstrate that in many cases the inclusion of subadults in analysis impacts upon the apparent mortality associated with cribra orbitalia. Examining cribra orbitalia in children and adults has two separate goals: in children, to determine the prevalence and risk of death associated with active lesions and stress; and in adults, to determine whether childhood health assaults that cause cribra orbitalia are associated with frailty or resilience.
目的
骨骼悖论认为,骨骼病变可能被不同地解释为代表韧性或脆弱性。然而,对个体骨骼指标的病因和人口分布的具体考虑,可以为区分压力、脆弱性和韧性提供依据。本研究采用生活史方法和适应性可塑性模型,提出了一个分析和解释常见报告的骨骼病变——筛状骨的框架,该框架考虑了该病症的潜在机制、与贫血和营养不良相关的临床和流行病学文献,以及生物考古学证据。
材料和方法
数据来自全球健康史项目的欧洲(n=33 个群体)和美洲(n=19 个群体)模块。应用了 Kaplan-Meier 和 Cox 回归分析,其中时间是死亡年龄,因子或协变量是筛状骨的存在或缺失。
结果
在产生显著结果的 37 个样本中,有 21 个在排除亚成年人分析时,其关系发生了变化。当包括亚成年人时,存在筛状骨的个体的生存时间具有统计学上的显著降低。排除亚成年人后,关系要么变得无统计学意义,要么发生逆转。
讨论
我们证明,在许多情况下,将亚成年人纳入分析会影响与筛状骨相关的明显死亡率。在儿童和成人中检查筛状骨有两个独立的目标:在儿童中,确定与活动性病变和压力相关的死亡率和风险;在成人中,确定导致筛状骨的儿童期健康攻击是否与脆弱性或韧性相关。
