目的：对头发和指甲等更新快的现代组织的碳和氮稳定同位素比率（C-13和N-15）的研究，已经确定了母乳喂养和断奶期间母亲及其婴儿的这些值之间的关系。使用胶原蛋白从高分辨率牙本质部分的牙齿，形成在围产期，我们调查之间的关系，饮食和生理在这个关键阶段的生活。材料和方法：儿童牙本质胶原蛋白C-13和N-15的配置文件产生的水平部分的恒牙和乳牙的发展方向。这些样本来自两个19世纪的遗址（n=24）和少量（n=5）来自英国和爱尔兰的史前样本。结果如下：这些高分辨率的数据显示，那些在童年时期幸存下来的人和那些没有幸存下来的人之间存在显著差异，前者变化很小，后者波动很大。讨论：母乳喂养和断奶行为对婴儿及其成年后的发病率和死亡率有显著影响。在缺乏文献证据的情况下，对成人和青少年骨胶原的考古研究被用来推断母乳喂养的流行程度和持续时间。这些解释依赖于对成年女性和死亡婴儿骨胶原中同位素比率之间关系的某些假设。这项研究的数据表明，一个更复杂的情况比以前提出的和潜在的一种新的方法来研究孕产妇和婴儿的健康在过去的人口。美国物理人类学杂志157：441-457，2015年。(c)2015 Wiley Periodicals，Inc.
Objectives: Studies of the carbon and nitrogen stable isotope ratios (C-13 and N-15) of modern tissues with a fast turnover, such as hair and fingernails, have established the relationship between these values in mothers and their infants during breastfeeding and weaning. Using collagen from high-resolution dentine sections of teeth, which form in the perinatal period we investigate the relationship between diet and physiology in this pivotal stage of life. Materials and Methods: Childhood dentine collagen C-13 and N-15 profiles were produced from horizontal sections of permanent and deciduous teeth following the direction of development. These were from two 19th-century sites (n=24) and a small number (n=5) of prehistoric samples from Great Britain and Ireland. Results: These high-resolution data exhibit marked differences between those who survived childhood and those who did not, the former varying little and the latter fluctuating widely. Discussion: Breastfeeding and weaning behavior have a significant impact on the morbidity and mortality of infants and the adults they become. In the absence of documentary evidence, archaeological studies of bone collagen of adults and juveniles have been used to infer the prevalence and duration of breastfeeding. These interpretations rely on certain assumptions about the relationship between isotope ratios in the bone collagen of the adult females and the infants who have died. The data from this study suggest a more complex situation than previously proposed and the potential for a new approach to the study of maternal and infant health in past populations.
