• Objectives. We evaluated the associations between chronic maternal stress measured by allostatic load (AL),maternal caretaking behaviors, and child dental caries experience. We also assessed the role of socioeconomic status in these associations. Methods. We used data from the Third National Health and Nutrition Examination Survey (1988-1994). We included children aged 2 to 6 years who linked to a maternal record (n = 716 maternal-child pairs). The main exposure was maternal AL index (0, 1, or ≥ 2). The primary outcome of interest was child dental caries experience (none or any). We evaluated the association between maternal AL and (1) maternal caretaking behaviors, and (2) child caries status and the role of socioeconomic status in these relationships. Results. Children of mothers with an AL index of at least 2 were significantly more likely to have not been breastfed and to have dental caries than were children of mothers with a normal AL before adjusting for measures of socioeconomic status. Conclusions. Maternal chronic stress, indicated by elevation in markers of AL, has an important role in child caretaking behaviors and in children's oral health. [ABSTRACT FROM AUTHOR]
