“…The fact that we find a link between prenatal stress, as assessed through self-reported anxiety in late gestation, and the initiation and duration of breastfeeding is not surprising given the extent of evidence for this relationship in other studies (Li et al 2008;Dozier et al 2012;Buck et al 2018). Indeed, higher levels of maternal stress are known to interfere with milk production and the let-down reflex, both through physiological interference in the hormonal pathways involved and through behavioural changes (Dewey 2001).…”

“…It is currently unclear to what extent the association between prenatal anxiety and breastfeeding might mediate these interactions between prenatal anxiety and later growth and age at onset of puberty. Such an effect is quite possible, as several studies already demonstrate a negative association between elevated maternal stress and breastfeeding, although these have small sample sizes, recall bias due to the use of retrospective questionnaires, or inappropriate adjustment for confounding (Dozier et al 2012;Fallon et al 2016;Buck et al 2018;Bublitz et al 2019).…”

Background: Stress experienced by mothers during pregnancy can have both immediate and long-term effects on child development, potentially mediated by breastfeeding. Aim: Using a UK birth cohort study, we asked how maternal stress relates to breastfeeding and consequences for growth and puberty onset. Subjects and methods: We analysed data from the Avon Longitudinal Study of Parents and Children, collected via questionnaires and clinic visits (N: 698-8,506). We used reports of prenatal anxiety, breastfeeding, early growth and age at menarche or first voice change. Confounding by maternal age, parity, smoking, education and body mass index (BMI) was considered. Results: Mothers with higher levels of reported anxiety were less likely to breastfeed (Odds ratio (OR): 0.83, 95% confidence interval (CI): 0.71, 0.97). Breastfed infants had slower growth before weaning, although growth differences were unclear thereafter. Being breastfed for more than six months was associated with later puberty onset in females (2.76 months later than non-breastfed; CI: 0.9, 4.63), although the association was attenuated by confounders and BMI (1.51 months, CI: À0.38, 3.40). No association between breastfeeding and puberty onset in males was found. Conclusion: Our studies fit results shown previously, and we consider these in light of evolutionary life history theory while discussing key challenges in such an approach.

“…It is also possible that a serious interpersonal LE during pregnancy is a proxy for other exposures or maternal behaviours (e.g. diet, sleep, prenatal care) that could affect the developing fetus, or mothers with serious interpersonal LEs during their pregnancy may continue to experience such events after the child's birth, influencing mother-child bonding, breastfeeding behaviour [43] and other parenting practices or environmental exposures that could affect the child.…”

First-appearing islet autoantibodies for type 1 diabetes in young children: maternal life events during pregnancy and the child’s genetic risk

et al. 2021

Aims/hypothesis Psychological stress has long been considered a possible trigger of type 1 diabetes, although prospective studies examining the link between psychological stress or life events during pregnancy and the child's type 1 diabetes risk are rare. The objective of this study was to examine the association between life events during pregnancy and first-appearing islet autoantibodies (IA) in young children, conditioned by the child's type 1 diabetes-related genetic risk. Methods The IA status of 7317 genetically at-risk The Environmental Determinants of Diabetes in the Young (TEDDY) participants was assessed every 3 months from 3 months to 4 years, and bi-annually thereafter. Reports of major life events during pregnancy were collected at study inception when the child was 3 months of age and placed into one of six categories. Life events during pregnancy were examined for association with first-appearing insulin (IAA) (N = 222) or GAD (GADA) (N = 209) autoantibodies in the child until 6 years of age using proportional hazard models. Relative excess risk due to interaction (RERI) by the child's HLA-DR and SNP profile was estimated. Results Overall, 65% of mothers reported a life event during pregnancy; disease/injury (25%), serious interpersonal (28%) and job-related (25%) life events were most common. The association of life events during pregnancy differed between IAA and GADA as the first-appearing autoantibody. Serious interpersonal life events correlated with increased risk of GADA-first only in HLA-DR3 children with the BACH2-T allele (HR 2.28, p < 0.0001), an additive interaction (RERI 1.87, p = 0.0004). Job-related life events were also associated with increased risk of GADA-first among HLA-DR3/4 children (HR 1.53, p = 0.04) independent of serious interpersonal life events (HR 1.90, p = 0.002), an additive interaction (RERI 1.19, p = 0.004). Job-related life events correlated with reduced risk of IAA-first (HR 0.55, p = 0.004), particularly in children with the BTNL2-GG allele (HR 0.48; 95% CI 0.31, 0.76).

Prenatal Exposure to Stressful Life Events and Infant Breastfeeding

Abstract: This study underscores the impact of exposure to prenatal SLE on breastfeeding initiation among postpartum women. Findings may assist providers in identifying at-risk women for anticipatory guidance to improve breastfeeding rates.
