This study reports the first dietary stable isotope data from Iron Age in Latvia. Archaeological, osteological, genetic, and stable isotope data from the Lejasbitēni cemetery were used to study gendered differences in childhood diet expressed in stable isotope ratios with social status expressed in grave goods, in this population from the 7th – 10th centuries CE.

Carbon and nitrogen isotope analysis showed significant differences in childhood diet between male and female gendered individuals, indicating that gender might have been a key factor for dietary differences in children. There were no significant dietary differences within the gender groups in adults of differential social status expressed in grave goods, suggesting no link between childhood diet and social status in adulthood, although the sample size was very small. A change towards a more hierarchical society was observed in the later period of the cemetery, expressed in the appearance of more elaborately furnished burials, rare grave goods, and a new burial tradition. All these changes were contemporary with the development of the Viking Age in Northern Europe, and thus possibly signified external cultural influence.

Ancient DNA analysis showed that gender as expressed by grave goods corresponded with biological sex in two individuals with the highest quality aDNA, while biological sex could not be confirmed in the other five tested individuals.

拉脱维亚 Lejasbitēni 铁器时代人口的饮食和社会地位

这项研究报告了拉脱维亚铁器时代的第一个膳食稳定同位素数据。来自 Lejasbitēni 墓地的考古学、骨学、遗传和稳定同位素数据被用于研究儿童饮食中的性别差异,这些差异以稳定同位素比率表示,社会地位以墓葬品表示,在公元 7世纪 至 10 世纪的这一人群中。

碳和氮同位素分析显示,男性和女性性别个体的儿童饮食存在显着差异,表明性别可能是儿童饮食差异的关键因素。尽管样本量非常小,但在社会地位不同的成年人中,性别组内的饮食差异没有显着差异,这表明儿童饮食与成年后的社会地位之间没有联系。在墓地的后期,人们观察到向等级更高的社会转变,表现为更精心布置的墓葬、稀有的随葬品和新的墓葬传统。所有这些变化都与北欧维京时代的发展同时发生,因此可能意味着外部文化影响。

古代DNA分析表明,墓葬所表达的性别与具有最高质量aDNA的两个个体的生物学性别相对应,而其他五个被测个体的生物学性别无法确认。
