Use of the theory of planned behavior framework to understand breastfeeding decision-making among mothers of preterm infants

Background: Mothers of preterm infants face significant challenges to breastfeeding. The theory of planned behavior (TPB) is a well-known framework comprising three domains (attitudes, perceived control, and social norms), which has been used to conceptualize the array of factors that influence health-related behaviors and develop interventions to promote behaviors. Aim: We used the TPB framework to determine the array of factors that contribute to breastfeeding among mothers of preterm infants. Materials and Methods: Using qualitative research methods, we conducted in-depth, semistructured interviews with mothers regarding their experiences feeding their preterm infants according to TPB domains. We developed themes based on an iterative process of review of transcripts and conducted interviews until thematic saturation was reached. Results: We interviewed 23 mothers in 3 states 2 to 6 months after hospital discharge; 22 mothers initiated milk production and 6 were breastfeeding at the time of the interview. Factors that were positive and negative toward breastfeeding were present for all three TPB domains. Regarding attitudes, mothers felt that breastfeeding was a way to bond, that breast milk was healthy and protective, and that breast milk alone was insufficient for a growing preterm infant. Regarding perceived control, mothers felt empowered to breastfeed due to encouragement from hospital staff, friends, and family, and had difficulty overcoming their infant's immature oral feeding skills, competing responsibilities, and perceived infant preference for bottle feeding. Regarding social norms, mothers reported support for and against breastfeeding among hospital and Special Supplemental Nutrition Program for Woman, Infants, and Children (WIC) providers, family, friends, and the media. Conclusion: Interventional studies geared toward breastfeeding promotion among mothers of preterm infants may focus on addressing barriers to direct breastfeeding during the neonatal intensive care unit and early post-discharge time periods

Social Determinants of Health and Parenting Self-Efficacy Among Mothers of Preterm Infants

Objective: To explore the relationships between social and environmental factors and parenting self-efficacy (PSE) among mothers of preterm infants hospitalized in neonatal intensive care units (NICUs) using a social determinants of health (SDoH) framework. Method: We analyzed data from a prospective cohort study that included 187 mother-infant dyads admitted to four NICUs in the Mountain West region between June 2017 and December 2019. We used multivariable linear regression models to assess the independent associations between maternal and infant characteristics and PSE. Results: Our final multiple linear regression model predicting the efficacy score including maternal race/ethnicity, age, insurance, employment status before giving birth, gestational age, depression, and having other children was significant (F(12,160) = 3.17, p = .0004, adjusted R¬2 = .131). Significant predictors of PSE were race/ethnicity (β= 3.3, p = .022), having another child/children (β= 4.2, p = .005), and depression (β= -4.2, p = .004). Conclusions: Findings suggest that social workers and medical practitioners should consider SDoH, such as insurance type, household income, and employment, along with traditional clinical indicators when assessing families’ infant care needs. Social workers, medical practitioners, and researchers should be mindful of how implicit bias may influence the allocation of care and parental supports

Normative modeling of brain morphometry in Clinical High-Risk for Psychosis

Importance: The lack of robust neuroanatomical markers of psychosis risk has been traditionally attributed to heterogeneity. A complementary hypothesis is that variation in neuroanatomical measures in the majority of individuals at psychosis risk may be nested within the range observed in healthy individuals. Objective: To quantify deviations from the normative range of neuroanatomical variation in individuals at clinical high-risk for psychosis (CHR-P) and evaluate their overlap with healthy variation and their association with positive symptoms, cognition, and conversion to a psychotic disorder. Design setting and participants: Clinical, IQ and FreeSurfer-derived regional measures of cortical thickness (CT), cortical surface area (SA), and subcortical volume (SV) from 1,340 CHR-P individuals [47.09% female; mean age: 20.75 (4.74) years] and 1,237 healthy individuals [44.70% female; mean age: 22.32 (4.95) years] from 29 international sites participating in the ENIGMA Clinical High Risk for Psychosis Working Group. Main outcomes and measures: For each regional morphometric measure, z-scores were computed that index the degree of deviation from the normative means of that measure in a healthy reference population (N=37,407). Average deviation scores (ADS) for CT, SA, SV, and globally across all measures (G) were generated by averaging the respective regional z-scores. Regression analyses were used to quantify the association of deviation scores with clinical severity and cognition and two-proportion z-tests to identify case-control differences in the proportion of individuals with infranormal (z1.96) scores. Results: CHR-P and healthy individuals overlapped in the distributions of the observed values, regional z-scores, and all ADS vales. The proportion of CHR-P individuals with infranormal or supranormal values in any metric was low (<12%) and similar to that of healthy individuals. CHR-P individuals who converted to psychosis compared to those who did not convert had a higher percentage of infranormal values in temporal regions (5-7% vs 0.9-1.4%). In the CHR-P group, only the ADS SA showed significant but weak associations (|β|<0.09; P FDR <0.05) with positive symptoms and IQ. Conclusions and relevance: The study findings challenge the usefulness of macroscale neuromorphometric measures as diagnostic biomarkers of psychosis risk and suggest that such measures do not provide an adequate explanation for psychosis risk. Key points: Question: Is the risk of psychosis associated with brain morphometric changes that deviate significantly from healthy variation?Findings: In this study of 1340 individuals high-risk for psychosis (CHR-P) and 1237 healthy participants, individual-level variation in macroscale neuromorphometric measures of the CHR-P group was largely nested within healthy variation and was not associated with the severity of positive psychotic symptoms or conversion to a psychotic disorder.Meaning: The findings suggest the macroscale neuromorphometric measures have limited utility as diagnostic biomarkers of psychosis risk

Normative modeling of brain morphometry in clinical high risk for psychosis

Importance The lack of robust neuroanatomical markers of psychosis risk has been traditionally attributed to heterogeneity. A complementary hypothesis is that variation in neuroanatomical measures in individuals at psychosis risk may be nested within the range observed in healthy individuals. Objective To quantify deviations from the normative range of neuroanatomical variation in individuals at clinical high risk for psychosis (CHR-P) and evaluate their overlap with healthy variation and their association with positive symptoms, cognition, and conversion to a psychotic disorder. Design, Setting, and Participants This case-control study used clinical-, IQ-, and neuroimaging software (FreeSurfer)–derived regional measures of cortical thickness (CT), cortical surface area (SA), and subcortical volume (SV) from 1340 individuals with CHR-P and 1237 healthy individuals pooled from 29 international sites participating in the Enhancing Neuroimaging Genetics Through Meta-analysis (ENIGMA) Clinical High Risk for Psychosis Working Group. Healthy individuals and individuals with CHR-P were matched on age and sex within each recruitment site. Data were analyzed between September 1, 2021, and November 30, 2022. Main Outcomes and Measures For each regional morphometric measure, deviation scores were computed as z scores indexing the degree of deviation from their normative means from a healthy reference population. Average deviation scores (ADS) were also calculated for regional CT, SA, and SV measures and globally across all measures. Regression analyses quantified the association of deviation scores with clinical severity and cognition, and 2-proportion z tests identified case-control differences in the proportion of individuals with infranormal (z &lt; −1.96) or supranormal (z &gt; 1.96) scores. Results Among 1340 individuals with CHR-P, 709 (52.91%) were male, and the mean (SD) age was 20.75 (4.74) years. Among 1237 healthy individuals, 684 (55.30%) were male, and the mean (SD) age was 22.32 (4.95) years. Individuals with CHR-P and healthy individuals overlapped in the distributions of the observed values, regional z scores, and all ADS values. For any given region, the proportion of individuals with CHR-P who had infranormal or supranormal values was low (up to 153 individuals [&lt;11.42%]) and similar to that of healthy individuals (&lt;115 individuals [&lt;9.30%]). Individuals with CHR-P who converted to a psychotic disorder had a higher percentage of infranormal values in temporal regions compared with those who did not convert (7.01% vs 1.38%) and healthy individuals (5.10% vs 0.89%). In the CHR-P group, only the ADS SA was associated with positive symptoms (β = −0.08; 95% CI, −0.13 to −0.02; P = .02 for false discovery rate) and IQ (β = 0.09; 95% CI, 0.02-0.15; P = .02 for false discovery rate). Conclusions and Relevance In this case-control study, findings suggest that macroscale neuromorphometric measures may not provide an adequate explanation of psychosis risk

An Integrative Review: Maternal Engagement in the Neonatal Intensive Care Unit and Health Outcomes for U.S.-Born Preterm Infants and Their Parents

Hospitals and perinatal organizations recognize the importance of family engagement in the neonatal intensive care unit (NICU). The Agency for Healthcare Research and Quality (AHRQ) defines family engagement as “A set of behaviors by patients, family members, and health professionals and a set of organizational policies and procedures that foster both the inclusion of patients and family members as active members of the health care team and collaborative partnerships with providers and provider organizations.” In-unit barriers and facilitators to enhance family engagement are well studied; however, less is known specifically about maternal engagement’s influence in the NICU on the health of infants and mothers, particularly within U.S. social and healthcare contexts. In this integrative review, we examine the relationship between maternal engagement in the NICU and preterm infant and maternal health outcomes within the U.S. Results from the 33 articles that met inclusion criteria indicate that maternal engagement in the NICU is associated with infant outcomes, maternal health-behavior outcomes, maternal mental health outcomes, maternal-child bonding outcomes, and breastfeeding outcomes. Skin-to-skin holding is the most studied maternal engagement activity in the U.S. preterm NICU population. Further research is needed to understand what types of engagement are most salient, how they should be measured, and which immediate outcomes are the best predictors of long-term health and well-being

The Role of Distance from Home to Hospital on Parental Experience in the NICU: A Qualitative Study

Prolonged admission to the neonatal intensive care unit presents challenges for families, especially those displaced far from home. Understanding specific barriers to parental engagement in the NICU is key to addressing these challenges with hospital-based interventions. The objective of this qualitative study was to explore the impact of distance from home to hospital on the engagement of parents of very preterm infants (VPT) in the neonatal intensive care unit (NICU). We used a grounded theory approach and conducted 13 qualitative interviews with parents of VPT who were admitted ≥14 days and resided ≥50 miles away using a semi-structured interview guide informed by the socio-ecological framework. We used constant comparative method with double coders for theme emergence. Our results highlight a multitude of facilitators and barriers to engagement. Facilitators included: (1) individual—delivery preparedness and social support; (2) environmental—medical team relationships; and (3) societal—access to perinatal care. Barriers included: (1) individual—transfer stressors, medical needs, mental health, and dependents; (2) environmental—NICU space, communication, and lack of technology; and (3) societal—lack of paid leave. NICU parents with geographic separation from home experienced a multitude of barriers to engagement, many of which could be addressed by hospital-based interventions

Defining an Infant\u27s Race and Ethnicity: A Systematic Review.

Infant race and ethnicity are used ubiquitously in research and reporting, though inconsistent approaches to data collection and definitions yield variable results. The consistency of these data has an impact on reported findings and outcomes

NICU Visitation Time and Adherence to Safe Sleep Practices Among Mothers of Very Preterm Infants.

Sleep-associated infant death is the leading cause of postneonatal mortality in the United States. Preterm infants are at higher risk for sleep-associated death, but maternal adherence to safe sleep practices is lower than for mothers of full-term infants. Data are lacking on whether maternal neonatal intensive care unit (NICU) visitation time impacts safe sleep compliance after hospital discharge

The Association of Social Factors and Time Spent in the NICU for Mothers of Very Preterm Infants.

METHODS In this prospective observational cohort study, we enrolled mother–infant dyads whose infants were bornweeks\u27 gestation. Enrollment occurred after 2 weeks of NICU exposure, when maternal social factors and demographic information was collected. Maternal time spent in the NICU was abstracted from the electronic medical record and was dichotomized into 0 to 6 days and ≥6 days per week. Demographic differences between the 2 groups were compared by using χ2 tests. Logistic regression was used to assess the independent association between maternal social factors and the average number of days per week spent in the NICU. RESULTS A total of 169 mother–infant dyads were analyzed. Maternal social factors associated with more time spent in the NICU included an annual household income of \u3e$100 000, compared with those with an annual household income of60 minutes [aOR: 7.85; 95% CI 2.81–21.96]), and the lack of other children in the household, compared with women with other children (aOR: 3.15; 95% CI 1.39–7.11). CONCLUSIONS Maternal time spent in the NICU during a prolonged birth hospitalization of a very preterm infant differed by socioeconomic status, travel time, and presence of other dependents. Strategies to better identify and reduce these disparities to optimize engagement and, subsequently, improve infant health outcomes is needed
