Breastfeeding and Weaning in Roman Thessaloniki. An Investigation of Infant Diet based on Incremental Analysis of Human Dentine

WEaning Age FiNder (WEAN): a tool for estimating weaning age from stable isotope ratios of dentinal collagen

“…Similarly, in the original publications, e.g. METi_125 (Ganiatsou et al 2022) and Cam9 T32c1 (King Based on the results, the estimations of WEAN are more accurate for isotopic profiles obtained from M1. Since WEAN uses the principle of the elbow method, it functions more efficiently with isotopic profiles that gradually decrease and stabilize.…”

“…Physiological stress during infancy may also implicate interpretations of isotopic ratios. For example, the degree of decrease in δ 15 N between breastfeeding and weaning age was used to explore underlying nutritional stress in some studies (Beaumont and Montgomery 2016;Ganiatsou et al 2022;King et al 2018). However, particular attention has recently been paid to examining physiological stress through isotopic patterns of opposing covariance.…”

“…WEAN re-estimated weaning ages from 119 out of 130 individuals (results shown in Table S1). The application could not estimate the weaning age in cases that the δ 15 N profile was not indicative of breastfeeding, e.g., Az115 T2, Az115 T6, and METi_67 (Ganiatsou et al 2022;King et al 2018), and in cases that the δ 15 N observations did not initiate from birth, e.g., B_93.2, B_76, B_42.1 (Scharlotta et al 2018), Changxinyuan_M074 (Miller et al 2020), MLP25 I1, Cam9 T32c1, Az75 T56, and Az71 T315 (King et al 2018). Identical observations were reported on the published datasets (Ganiatsou et al 2022;King et al 2018;Miller et al 2020;Scharlotta et al 2018).…”

“…The abovementioned studies pursue the aim of increasing the temporal resolution of the isotopic analysis and reconstructing intra-individual dietary changes across childhood. However, albeit infant feeding practices are often investigated using incremental dentine stable isotope analysis, the estimation of weaning onset and completion are performed visually (Ganiatsou et al 2022;Lee et al 2020;Scharlotta et al 2018).…”

Prehrana dojenčkov v antičnem Rimu

“…44 Pri dojenju pa so lahko pojavljali problemi zaradi prehrane matere, kar zasledimo pri analizi zob. 45 Z ozirom na slabo učinkovitost nadomestnega hranjenja torej poudarjanje dojenja in materinega mleka kot najboljše izbire ni bilo le vprašanje virtūtēs.…”
