The role of sociodemographic factors in maternal psychological distress and mother-preterm infant interactions.

ABSTRACT: Preterm birth has been associated with greater psychological distress and less positive mother infant interactions than were experienced by mothers of full-term infants. Maternal and infant sociodemographic factors have also shown a strong association with psychological distress and the mother-infant relationship. However, findings on their effects over time are limited. In this longitudinal analysis, we explored the relationship of maternal and infant sociodemographic variables (maternal age, maternal education, marital status, being on social assistance, maternal race, infant birth weight, and infant gender) to maternal psychological distress (depressive, posttraumatic stress, anxiety, parenting stress symptoms, and maternal worry about child's health) through 12 months corrected age for prematurity, and on the home environment, and mother-infant interactions through 6 months corrected age for prematurity. We also explored differences related to maternal obstetrical characteristics (gestational age at birth, parity, mode of delivery, and multiple birth) and severity of infant conditions (Apgar scores, need for mechanical ventilation, and infant medical complications). Although the relationship of maternal and infant characteristics with these outcomes did not change over time, psychological distress differed based on marital status, maternal education, infant gender, and infant medical complications. Older mothers provided more a positive home environment. Mother-infant interactions differed by maternal age, being on public assistance, maternal race, infant gender, and infant medical complications. More longitudinal research is needed to better understand these effects over time in order to identify and support at-risk mothers.

Project description:ObjectiveFindings from animal studies indicate that the early gut bacteriome is a potential mechanism linking maternal prenatal stress with health trajectories in offspring. However, clinical studies are scarce and the associations of maternal psychological profiles with the early infant faecal bacteriome are unknown. This study aimed to investigate the associations of prenatal stressors and distress with early infant faecal bacterial profiles in a South African birth cohort study.MethodsAssociations between prenatal symptoms of depression, distress, intimate partner violence (IPV) and posttraumatic stress disorder (PTSD) and faecal bacterial profiles were evaluated in meconium and subsequent stool specimens from 84 mothers and 101 infants at birth, and longitudinally from a subset of 69 and 36 infants at 4-12 and 20-28 weeks of age, respectively, in a South African birth cohort study.ResultsInfants born to mothers that were exposed to high levels of IPV had significantly higher proportions of Citrobacter and three unclassified genera, all of which belonging to the family Enterobacteriaceae detected at birth. Proportions of these Enterobacteriaceae remained significantly increased over time (birth to 20-28 weeks of life) in infants born to mothers with high levels of IPV exposure compared to infants from mothers with no/low IPV exposure. Infants born to mothers exposed to IPV also had higher proportions of the genus Weissella at 4-12 weeks compared to infants from mothers with no/low IPV exposure. Faecal specimens from mothers exposed to IPV had higher proportions of the family Lactobacillaceae and lower proportions of Peptostreptococcaceae at birth. Maternal psychological distress was associated with decreased proportions of the family Veillonellaceae in infants at 20-28 weeks and a slower decline in Gammaproteobacteria over time. No changes in beta diversity were apparent for maternal or infant faecal bacterial profiles in relation to any of the prenatal measures for psychological adversities.ConclusionMaternal lifetime IPV and antenatal psychological distress are associated with altered bacterial profiles in infant and maternal faecal bacteria. These findings may provide insights in the involvement of the gut bacteria linking maternal psychological adversity and the maturing infant brain.

Project description:Background:Breastfeeding is of great importance for infant health both short and long term, especially for those born preterm. Apart from the socio-economic and cultural factors which may influence a mother's decision on breastfeeding, lactation performance is also influenced by maternal physiological and psychological condition, as well as infant behavioural factors. The aim of this project is to investigate physiological, psychological and anthropological aspects of 'signalling' between mother and infant during lactation in a stressful situation, following late preterm delivery, using an experimental approach. Method:A single blind parallel randomised controlled trial will be conducted in Chinese primiparous mothers who deliver a infant (34 0/7-37 6/7) weeks and plan to exclusively breastfeed. Mothers will be recruited from four local community clinics attached to Beijing Children Hospital. Two home visits will be arranged at one week and eight weeks postpartum. Participants will be randomly assigned to either intervention arm or control (no intervention) before the first home visit. Mothers from the intervention group will be asked to listen to an audio recording with relaxation meditation daily during breastfeeding. Maternal stress and anxiety will be measured at one week and eight week postpartum using Chinese version of Cohen's Perceived Stress Scale (PSS) and Beck Anxiety Inventory (BAI). Infant weight and length gain (as SD scores) from one to eight week will be measured using anthropometry. Milk volume will be measured using 48-h test-weighing method. Breast milk samples and mother and infant's stool samples will be collected to measure macronutrient and microbiome content. Anthropometric measurements (weight, length and head circumference) will be performed during all home visits. Discussion:Primary outcomes of this study will be the effect of the intervention on maternal psychological state, and infant growth. Other outcomes will include the effect of the intervention on milk production, infant behaviours, and the microbiome composition in breastmilk and maternal and infant's gut. Results of this study will provide greater understanding about maternal-infant factors which influence the success of breastfeeding, and which may then be useful targets for future interventions.

Project description:ObjectiveThe authors explored the relationship of cord-maternal antidepressant concentration ratios and maternal depression with perinatal events and preterm birth.MethodThe investigators examined 21 mother-infant pairs that had antidepressant exposure during pregnancy. The antidepressants included serotonin reuptake inhibitors (SRIs) and nortriptyline (a norepinephrine inhibitor and mild SRI). The mothers were evaluated with the Structured Clinical Interview for DSM-IV. Depression ratings were repeated at 20, 30, and 36 weeks' pregnancy. At delivery, investigators assessed cord and maternal antidepressant concentrations, neonatal outcomes on the Peripartum Events Scale (PES), and gestational weeks at birth. The investigators performed this study at the Women's Behavioral HealthCARE Program, Western Psychiatric Institute and Clinic, University of Pittsburgh Medical Center, Pennsylvania, from April 2003 until September 2006.ResultsMean ± SD cord-to-maternal concentration ratios were 0.52 ± 0.35 (range, 0.00-1.64) for the parent drug and 0.54 ± 0.17 (range, 0.28-0.79) for the metabolite. Nine of 21 mothers (43%) had a major depressive episode. From examining the maximum depression ratings, the mean ± SD Structured Interview Guide for the Hamilton Depression Rating Scale, Atypical Depression Symptoms Version score was 16.0 ± 7.6. One third (7/21) of infants had at least 1 perinatal event (PES ≥ 1). The frequency of deliveries complicated by any perinatal event was similar in depressed and nondepressed mothers. There was no significant association between perinatal events and cord-to-maternal antidepressant concentration ratios or maternal depression levels. Exposure to short half-life antidepressants compared to fluoxetine resulted in more perinatal events (7/16 = 44% vs 0/5 = 0%; P = .06). Fourteen percent (3/21) of infants were preterm. Preterm birth was not associated with cord-to-maternal metabolite concentration ratios, depression levels, or exposure to fluoxetine.ConclusionsAntidepressant-exposed infants experienced a limited number of transient perinatal events. No association between cord-maternal concentration ratios or maternal depression and perinatal events could be identified. Contrary to other reports, we detected no increased risk for perinatal events with fluoxetine therapy compared to the short half-life antidepressants.Trial registrationclinicaltrials.gov Identifier: NCT00279370.

Project description:BackgroundLate preterm infants suffer from more complications and are less likely to be breastfed compared to term infants and their mothers experience higher levels of stress than mothers with term infants. The physiological or hormonal responses that influence milk ejection, milk production, and/or maternal behaviour are possible mechanisms by which maternal distress could negatively influence breastfeeding success. Maternal mood might also affect infant behaviour (feeding, sleeping, and crying) through changes in milk volume and composition, and consequently breastfeeding success and infant growth. Previous research, using relaxation therapy in 64 Malaysian first-time mothers breastfeeding their full-term infants, demonstrated that the therapy was effective in reducing maternal stress and improving infant growth. We hypothesise that expected benefits are even greater in a more vulnerable population where additional breastfeeding support is especially needed, such as in mothers of late preterm infants.Methods/designThis protocol describes our randomised controlled trial that tests whether a breastfeeding meditation audio reduces maternal stress in mothers of late preterm infants in London. Home visits will be conducted at 2-3 and 6-8 weeks post-delivery. Participants will be randomised to a control group or an intervention group, where mothers will be asked to listen to a meditation tape on a daily basis while breastfeeding. The main outcomes of the intervention will be maternal stress markers and infant weight Z-score. Potential mediators will be the secondary outcomes and include breast milk macronutrient and hormone levels (ghrelin, leptin, cortisol, and adiponectin), milk volume assessed by 48-h test-weighing, and maternal engagement with the infant. Infant behaviour, including crying and sleeping, and infant appetite will be evaluated. Data about other mediators such as maternal perception of milk supply and salivary oxytocin will be collected.DiscussionWe hypothesise that the use of the breastfeeding meditation will reduce maternal stress and consequently improve infant growth mediated by changes in milk composition and volume and maternal behaviour. This study will allow us to understand the mother-infant factors that influence breastfeeding in late preterm infants and potentially identify a method that could improve mother, infant, and breastfeeding outcomes.Trial registrationClinicalTrials.gov, NCT03791749.
