“…Although both of these studies were conducted with samples of full-term infants, it is possible that feeding route may be related to interaction quality for preterm infants as well. Previous research has also shown that full-term breastfed infants exhibit higher HRV and vagal tone, compared with full-term bottle fed infants (Butte, O’Brian Smith, & Garza, 1991; DiPietro, Larson, & Porges, 1987; Jacob, Byrne, & Keenan, 2009), suggesting possible differences in early infant physiological regulation related to feeding that may also predict interaction quality.…”

This longitudinal study examined predictors of rates of growth in dyadic interaction quality in children born preterm who did not experience significant neurological findings during neonatal intensive care unit (NICU) hospitalization. Multiple methods were used to collect data from 120 preterm infants (48% girls, 52% boys) and their mothers. Infant heart rate variability (HRV), gestational age, neonatal health, feeding route, and maternal socioeconomic (SES) risks were assessed at NICU discharge (mean of 36 weeks postconception). Mother–child interactions were observed at 4, 9, 16, and 24 months postterm and analyzed with hierarchical linear modeling. On average, children’s quality of play, interest, and attention increased over time while their dysregulation and irritability decreased, whereas average maternal positive affect and involvement declined in quality (ps < .05), although there was individual variation in rates of change. Mothers of infants with higher postfeeding HRV (i.e., vagal regulation) exhibited less decrease in positive affect and involvement between 4 months and 24 months, compared with mothers of infants with lower HRV (p < .05). Although infants with higher postfeeding HRV showed less positive affect and communication at 4 months, they exhibited significantly greater increases in positive affect and social competence and decreases in dysregulation and irritability between 4 months and 24 months, compared with infants with lower HRV (ps < .05). Dyads experiencing more SES risks showed less optimal interactions at 4 months; this difference remained as children grew older (ps < .05). Results have implications for our understanding of social development in preterm infants.

“…Findings in studies employing biomarkers of emotional SR also find that poorer rearing contexts can have a negative influence on children’s emotional SR (Jacob, Bryne, & Keenan, 2009; but see Blair et al, 2013, who did not find a relation between cumulative risk and children’s RSA).…”

This review examines mechanisms contributing to the intergenerational transmission of self-regulation. To provide an integrated account of how self-regulation is transmitted across generations, we draw from over 75 years of accumulated evidence, spanning case studies to experimental approaches, in literatures covering developmental, social, and clinical psychology, and criminology, physiology, genetics, and human and animal neuroscience (among others). First, we present a taxonomy of what self-regulation is and then examine how it develops – overviews that guide the main foci of the review. Next, studies supporting an association between parent and child self-regulation are reviewed. Subsequently, literature that considers potential social mechanisms of transmission, specifically parenting behavior, inter-parental (i.e., marital) relationship behaviors, and broader rearing influences (e.g., household chaos) are considered. Finally, literature providing evidence that prenatal programming may be the starting point of the intergenerational transmission of self-regulation is covered, along with key findings from the behavioral and molecular genetics literatures. To integrate these literatures, we introduce the Self-Regulation Intergenerational Transmission Model, a framework that brings together prenatal, social, and neurobiological mechanisms (spanning endocrine, neural, and genetic levels, including gene-environment interplay and epigenetic processes) to explain the intergenerational transmission of self-regulation. This model also incorporates potential transactional processes between generations (e.g., children’s self-regulation and parent-child interaction dynamics that may affect parents’ self-regulation) that further influence intergenerational processes. In pointing the way forward, we note key future directions and ways to address limitations in existing work throughout the review and in closing. We also conclude by noting several implications for intervention work.

“…19–21 In utero, maternal stress has an almost immediate impact on fetal ANS activity, and maternal chronic stress and depression predict neonate ANS activity. 22,23 High prenatal stress has been shown to predict blunted RSA recovery following the SFP in 6-month-old infants, with effects persisting into childhood. 2,3,24 In addition to prenatal influences, genetic factors and maternal experiences prior to pregnancy may also contribute to the development of the ANS.…”

Objective Respiratory sinus arrhythmia (RSA) is a parasympathetic-mediated biomarker of self-regulation linked to lifespan mental and physical health outcomes. Intergenerational impacts of mothers’ exposure to prenatal stress have been demonstrated, but evidence for biological embedding of maternal preconception stress, including adverse childhood experiences (ACEs), on infant RSA is lacking. We examine the independent effects of maternal ACEs and prenatal stress on infant RSA, seeking to broaden the understanding of the earliest origins of mental and physical health risk. Method Mothers reported on ACEs and prenatal stress. RSA was recorded in a sample of 167 4-month-old infants (49% female and 51% male) during a dyadic stressor, the Still Face Paradigm. Results Independent contributions of maternal ACEs and prenatal stress to infant RSA were observed. High maternal ACEs were associated with lower RSA, whereas prenatal stress was associated with failure to recover following the stressor. Sex but not race differences were observed. Prenatal stress was associated with higher RSA among boys but lower RSA among girls. Conclusion Infants’ RSA is affected by mothers’ life course experiences of stress, with ACEs predicting a lower set point and prenatal stress dampening recovery from stress. For prenatal stress but not ACEs, patterns vary across sex. Findings underscore that stress-reducing interventions for pregnant women or those considering pregnancy may lead to decreased physical and mental health risk across generations.
