Hurricane Katrina-related maternal stress, maternal mental health, and early infant temperament.

ABSTRACT: To investigate temperament in infants whose mothers were exposed to Hurricane Katrina and its aftermath, and to determine if high hurricane exposure is associated with difficult infant temperament. A prospective cohort study of women giving birth in New Orleans and Baton Rouge, LA (n = 288) in 2006-2007 was conducted. Questionnaires and interviews assessed the mother's experiences during the hurricane, living conditions, and psychological symptoms, 2 months and 12 months postpartum. Infant temperament characteristics were reported by the mother using the activity, adaptability, approach, intensity, and mood scales of the Early Infant and Toddler Temperament Questionnaires, and "difficult temperament" was defined as scoring in the top quartile for three or more of the scales. Logistic regression was used to examine the association between hurricane experience, mental health, and infant temperament. Serious experiences of the hurricane did not strongly increase the risk of difficult infant temperament (association with three or more serious experiences of the hurricane: adjusted odds ratio (aOR) 1.50, 95% confidence interval (CI) 0.63-3.58 at 2 months; 0.58, 0.15-2.28 at 12 months). Maternal mental health was associated with report of difficult infant temperament, with women more likely to report having a difficult infant temperament at 1 year if they had screened positive for PTSD (aOR 1.82, 95% confidence interval (CI) 0.61-5.41), depression, (aOR 3.16, 95% CI 1.22-8.20) or hostility (aOR 2.17, 95% CI 0.81-5.82) at 2 months. Large associations between maternal stress due to a natural disaster and infant temperament were not seen, but maternal mental health was associated with reporting difficult temperament. Further research is needed to determine the effects of maternal exposure to disasters on child temperament, but in order to help babies born in the aftermath of disaster, the focus may need to be on the mother's mental health.

Project description:BackgroundStudies have shown that infant temperament varies with maternal psychosocial factors, in utero illness, and environmental stressors. We predicted that the pandemic would shape infant temperament through maternal SARS-CoV-2 infection during pregnancy and/or maternal postnatal stress. To test this, we examined associations among infant temperament, maternal prenatal SARS-CoV-2 infection, maternal postnatal stress, and postnatal COVID-related life disruptions.MethodsWe tested 63 mother-infant dyads with prenatal maternal SARS-CoV-2 infections and a comparable group of 110 dyads without infections. To assess postnatal maternal stress, mothers completed the Perceived Stress Scale 4 months postpartum and an evaluation of COVID-related stress and life disruptions 6 months postpartum. Mothers reported on infant temperament when infants were 6-months-old using the Infant Behavior Questionnaire-Revised (IBQ-R) Very Short Form.ResultsMaternal SARS-CoV-2 infection during pregnancy was not associated with infant temperament or maternal postnatal stress. Mothers with higher self-reported postnatal stress rated their infants lower on the Positive Affectivity/Surgency and Orienting/Regulation IBQ-R subscales. Mothers who reported greater COVID-related life disruptions rated their infants higher on the Negative Emotionality IBQ-R subscale.ConclusionsDespite no effect of prenatal maternal SARS-CoV-2 infection, stress and life disruptions incurred by the COVID-19 pandemic were associated with infant temperament at 6-months.ImpactSARS-CoV-2 infection during pregnancy is not associated with postnatal ratings of COVID-related life disruptions, maternal stress, or infant temperament. Postnatal ratings of maternal stress during the COVID-19 pandemic are associated with normative variation in maternal report of infant temperament at 6 months of age. Higher postnatal ratings of maternal stress are associated with lower scores on infant Positive Affectivity/Surgency and Orienting/Regulation at 6 months of age. Higher postnatal ratings of COVID-related life disruptions are associated with higher scores on infant Negative Emotionality at 6 months of age.

Project description:Infant mental health is interconnected with and affected by maternal mental health. A mother or birthing person's mental health before and during pregnancy and the postpartum period is essential for a child's development. During the first year of life, infants require emotional attachment and bonding to strive. Perinatal mood disorders are likely to hinder attachment and are associated with an increased risk of adverse mental health effects for children later in life. The Black community is faced with a crisis as Black mothers experience a higher prevalence of perinatal mood disorders, including postpartum depression and anxiety, compared to the United States national estimates. The aim of the research is to identify social, structural, and economic disparities of Black perinatal women and birthing people's experience to understand the impact of perinatal mental health on infants' mental health. Black mothers and birthing people may often face social and structural barriers that limit their opportunity to seek and engage with interventions and treatment that address the root causes of their perinatal mood disorder. To enhance understanding of racial disparities caused by social and structural determinants of health on Black mothers and birthing people's mental health and health care experiences that influence infant mental health, the study team conducted semi-structured interviews among self-identified cisgender Black women health professionals nationwide, who provide care to pregnant or postpartum Black women and birthing people. Our study attempted to identify themes, pathways, interventions, and strategies to promote equitable and anti-racist maternal and infant mental health care. Using a Rigorous and Accelerated Data Reduction (Radar) technique and a deductive qualitative analytic approach it was found that limited access to resources, lack of universal screening and mental health education, and the disjointed healthcare system serves as barriers, contribute to mental health issues, and put Black mothers and birthing people at a disadvantage in autonomous decision making. Our study concluded that instituting education on healthy and culturally appropriate ways to support infant development in parent education programs may support Black parents in establishing healthy attachment and bonds. Prioritizing strategies to improve maternal mental health and centering Black parents in developing these educational parenting programs may optimize parenting experiences.

Project description:BackgroundGene-environment interactions mediate through the placenta and shape the fetal brain development. Between the environmental determinants of the fetal brain, maternal psychosocial stress in pregnancy has been shown to negatively influence the infant temperament development. This in turn may have adverse consequences on the infant neurodevelopment extending throughout the entire life-span. However little is known about the underlying biological mechanisms of the effects of maternal psychosocial stress in pregnancy on infant temperament. Environmental stressors such as maternal psychosocial stress in pregnancy activate the stress response cascade that in turn drives the increase in the cellular energy demand of vital organs with high metabolic rates such as, in pregnancy, the placenta. Key players of the stress response cascade are the mitochondria.ResultsHere, we tested the expression of all 13 protein-coding genes encoded by the mitochondria in 108 placenta samples from the Stress in Pregnancy birth cohort, a study that aims at determining the influence of in utero exposure to maternal psychosocial stress in pregnancy on infant temperament. We showed that the expression of the protein-coding mitochondrial-encoded gene MT-ND2 was positively associated with indices of maternal psychosocial stress in pregnancy including Prenatal Perceived Stress (β = 0.259; p-regression = 0.004; r2-regression = 0.120), State Anxiety (β = 0.218; p-regression = 0.003; r2-regression = 0.153), Trait Anxiety (β = 0.262; p-regression = 0.003; r2-regression = 0.129) and Pregnancy Anxiety Total (β = 0.208; p-regression = 0.010; r2-regression = 0.103). In the meantime MT-ND2 was negatively associated with the infant temperament indices of Activity Level (β = -0.257; p-regression = 0.008; r2-regression = 0.165) and Smile and Laughter (β = -0.286; p-regression = 0.036; r2-regression = 0.082). Additionally, MT-ND6 was associated with the maternal psychosocial stress in pregnancy index of Prenatal Perceived Stress (β = -0.231; p-regression = 0.004; r2-regression = 0.120), while MT-CO2 was associated with the maternal psychosocial stress in pregnancy indices of State Anxiety (β = 0.206; p-regression = 0.003; r2-regression = 0.153) and Trait Anxiety (β = 0.205; p-regression = 0.003; r2-regression = 0.129).ConclusionsOur data support the role of mitochondria in responding to maternal psychosocial stress in pregnancy, as assessed in placenta, while also suggesting an important role for the mitochondria in the infant temperament development.
