Mother's level of confidence in caring for her late preterm infant: A mixed methods study.

AIM AND OBJECTIVES: To examine what it means to be a mother of a late preterm infant including a mother's level of confidence in caring for her late preterm infant over time and the effect of maternal depression of this experience. BACKGROUND: Little is known about mothers' experiences of caring for their late preterm infants in the community, including their level of confidence and parenting stress within the context of a supported care environment by public health nurses. DESIGN: A mixed methods study, sequential explanatory quantitative and qualitative study. METHODS: A convenience sample of mothers with LPIs (n = 71) completed questionnaires on maternal confidence (3-4 weeks and 6-8 weeks), parenting stress (6-8 weeks), social support (6-8 weeks) and postpartum depression (6-8 weeks). A purposive sample of mothers (n = 11) underwent in-depth, semi-structured interviews. RESULTS: Maternal confidence decreased from 3-4 weeks-6-8 weeks after delivery, and similar results were found for mothers who reported depressive symptoms. Narratives of the mothers suggested the decrease in maternal confidence over time was influenced by the demanding characteristics of the late preterm infant, the prospect of their rehospitalisation and the mother's reported interactions with public health nurses. Depression had an effect on maternal confidence; that is, the depressed mothers demonstrated less confidence about their caretaking role than the nondepressed mothers at 6-8 weeks. Mothers did not discuss mental health issues, which may reflect the protective effects of social support on emotional instability or an inability to recognise postpartum depression. CONCLUSION: The confidence of mothers with LPIs decreased over the first 2 months following delivery and being home with their infants. Assisting mothers to meet their personal needs and the needs of their infant should promote maternal skills, which will likely increase maternal confidence related to the care of their late preterm infant. RELEVANCE FOR CLINICAL PRACTICE: Characteristics of LPIs contributed more to parenting stress score than parent characteristics; mothers however attempted to normalise the late preterm infant in order to minimise the parenting stress. Evidence-informed brief interventions tailored based on late preterm infant and parent characteristics may improve maternal confidence over time. Healthcare professional should provide education and anticipatory guidance prior to discharge, consistent care in hospital and postdischarge as this may impact maternal level of confidence. Future research needs to examine standards of care for discharge of LPIs and adherence to these standards.

Prenatal allostatic load and preterm birth: A systematic review.

Objective: Allostatic load refers to cumulative neuroendocrine burden and has been postulated to mediate and moderate physiological and psychological stress-related responses. This may have important implications for the risk of preterm birth. This systematic review examines the evidence on the association between prenatal allostatic load and preterm birth. Data sources: A comprehensive search of seven electronic databases was conducted from inception to August 23, 2022 to identify all English-language observational and mixed methods studies examining allostatic load and preterm birth with no year or geographic restrictions. Study eligibility criteria: Studies were included if they measured allostatic load, evaluated as the cumulative effect of any combination of more than one allostatic load biomarker, during pregnancy. Studies must have observed preterm birth, defined as < 37 weeks' gestational age, as a primary or secondary outcome of interest. Study appraisal and synthesis methods: The Quality In Prognosis Studies tool was used to evaluate risk of bias within included studies. A narrative synthesis was conducted to explore potential associations between allostatic load and preterm birth, and sources of heterogeneity. Results: Three prospective cohort studies were identified and revealed mixed evidence for an association between allostatic load and preterm birth. One study reported a statistically significant association while the other two studies reported little to no evidence for an association. Heterogeneity in when and how allostatic load was measured, limitations in study design and cohort socio-demographics may have contributed to the mixed evidence. Conclusions: This review provides insight into key individual-, community-, and study-level characteristics that may influence the association between allostatic load and preterm birth. Knowledge gaps are identified as foci for future research, including heterogeneity in allostatic load biomarkers and allostatic load index algorithms as well as pregnancy-specific considerations for allostatic load measurement. Further investigation of the allostatic load framework in the context of perinatal mental health is needed to advance understandings of maternal, infant, and child health.

Prenatal Maternal Anxiety as a Risk Factor for Preterm Birth and the Effects of Heterogeneity on This Relationship: A Systematic Review and Meta-Analysis.

Background. Systematic reviews (SR) and meta-analyses (MA) that previously explored the relationship between prenatal maternal anxiety (PMA) and preterm birth (PTB) have not been comprehensive in study inclusion, failing to account for effects of heterogeneity and disagree in their conclusions. Objectives. This SRMA provides a summary of the published evidence of the relationship between PMA and PTB while examining methodological and statistical sources of heterogeneity. Methods. Published studies from MEDLINE, CINAHL, PsycINFO, and EMBASE, until June 2015, were extracted and reviewed. Results. Of the 37 eligible studies, 31 were used in this MA; six more were subsequently excluded due to statistical issues, substantially reducing the heterogeneity. The odds ratio for PMA was 1.70 (95% CI 1.33, 2.18) for PTB and 1.67 (95% CI 1.35, 2.07) for spontaneous PTB comparing higher levels of anxiety to lower levels. Conclusions. Consistent findings indicate a significant association between PMA and PTB. Due to the statistical problem of including collinear variables in a single regression model, it is hard to distinguish the effect of the various types of psychosocial distress on PTB. However, a prenatal program aimed at addressing mental health issues could be designed and evaluated using a randomised controlled trial to assess the causal nature of different aspects of mental health on PTB.
