Existing studies in low-income societies largely use broad proxies for caregiving behaviors rather than measuring childcare activities, which may mask variation in allomothering and, thus, its impact on children's health. Using data collected to address these limitations we measure, for 808 children under 5 years in Northwestern Tanzania: (a) Maternal residence, (b) receipt of two childcare types from seven caregivers; and (c) children's growth (height-for-age and weight-for-height). We predict that (1) allomothering will be beneficial for children's growth and (2) benefits of allomothering will be most evident within mother nonresident households. We demonstrate that children receive care from a range of allomothers, even when mothers co-reside; and there are associations between care from different relatives. Receiving care from relatives of the same lineage tends to be positively associated, whereas care from fathers is negatively associated with care from maternal relatives. Maternal residence is not associated with child growth. We find little support for our predictions, with few and inconsistent associations between allomothering and child growth. Our findings suggest that our measures of care, while more nuanced than previous proxies, do not fully capture the complexity of caregiving. Pathways between allomothering and child growth may be further elucidated through more comprehensive care indicators, which specifically measure maternal need for help, and whether allomothering is in addition to, or substitutive of, maternal care.</p>","PeriodicalId":50809,"journal":{"name":"American Journal of Human Biology","volume":"37 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajhb.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A strong influence of agropastoral activity and Catholic practices on the social organization of this community was evidenced by the seasonality of conceptions and marriages. The disappearance of the traditional family and inheritance system at the end of the century was illustrated by a decreased age at marriage and a declining nuptiality rate. We confirmed the very high level of valley endogamy associated with a relatively intense degree of intra-valley marriage-associated mobility. A series of mortality crises related to epidemics (some cases documented: cholera, smallpox, and dysentery) was detected. Migration to Argentina and Uruguay was organized, especially between 1866 and 1872, including mainly nonfirstborn males who did not inherit familial property.
