Mothers Falling Asleep During Infant Feeding.

Falling asleep while feeding (FAF) infants is common. Our primary objectives were to examine (1) maternally reported prevalence of FAF and if planned; (2) association between FAF and sociodemographic factors, feeding method, and sleep location; and (3) if receipt of education about safe sleep and bedsharing risks was associated with FAF. In the Social Media and Risk-reduction Training study, US mothers of newborns were randomized to educational messaging promoting infant safe sleep or breastfeeding. We analyzed data from 1259 mothers who responded to the postpartum survey (mean infant age, 11.2 weeks). We used generalized estimating equation logistic regression models to examine the extent that sociodemographic characteristics, feeding type, usual nighttime feeding location, and intervention group were associated with FAF. A total of 28.2% of mothers reported FAF usually or sometimes in the last 2 weeks, 83.4% of whom reported that FAF was unplanned. There were no differences in the odds of FAF by sociodemographic factors. Compared with mothers whose nighttime feeding location was their bed, mothers who reported feeding in a chair were less likely to FAF (33.6% versus 16.8%; adjusted odds ratio, 0.41; 95% confidence interval, 0.31-0.56). FAF was reported less frequently by mothers who received safe sleep interventions (15.6%), compared with mothers who received breastfeeding interventions (33.0%; adjusted odds ratio, 0.40; 95% confidence interval, 0.25-0.65). FAF is reported commonly among US mothers and is predominantly unplanned. Mothers who received safe sleep messaging were less likely to report FAF. New parents need guidance on planning for optimal safety during infant feeding.

Using Sudden Unexpected Infant Death-Case Registry Data to Drive Prevention.

Sudden unexpected infant death (SUID) is a major contributor to infant death and a persistent public health issue. After an initial decline after the 1994 "Back to Sleep" campaign, SUID numbers plateaued. Currently, ∼10 infants die suddenly and unexpectedly each day in the United States. In 2019, we established a surveillance system for SUID in Cook County, Illinois, partnering our academic medical center, the Cook County Medical Examiner's Office, and child death review to create the Cook County SUID Case Registry. Our data show that, in Cook County, including the city of Chicago, ∼1 infant dies unexpectedly during sleep every week. Of these SUID, ∼25% were because of suffocation/possible suffocation. SUID peaks at 30 to 60 days old. SUID rates are 15 times higher in non-Hispanic Black infants and 3 times higher in Hispanic infants, compared with white infants. Nearly all involved 1 or more unsafe sleep factors. SUID are concentrated in community areas experiencing high hardship. Through our Community Partnership Approaches for Safe Sleep-Chicago team, we have developed collaborative prevention approaches in affected communities, allowing for conversations with families and those who support them to better understand barriers to safe sleep that they experience. These partnerships and our data allow for tailoring of informed prevention approaches to address upstream factors driving disproportionate infant mortality in historically disinvested communities, as well as optimizing the immediate risks posed by the infant sleep environment. Data from our system show the number of SUID declining modestly since our prevention work began.

Collaboration to Reduce Sudden Unexpected Infant Death With Child Fatality Review and Outreach.

Sudden unexpected infant death (SUID) is the leading cause of postneonatal infant mortality in the United States, with disproportionately high rates in Baltimore City and Baltimore County in Maryland. This Advocacy Case Study describes the collaboration between the City and County Child Fatality Review teams to decrease infant mortality. B'more for Healthy Babies, formed in 2009 by the Bureau of Maternal Child Health in Baltimore City with the goal of reducing infant mortality through policy change, service improvements, community mobilization, and behavior change has had a sustained effort to respond to SUID. Recognizing that infants born in Baltimore City often reside in Baltimore County (and vice versa), collaboration with Baltimore County has been essential to increasing B'more for Healthy Babies' scope, reach, and effectiveness. Public health messaging campaigns, creation, and dissemination of a "SLEEP SAFE" testimonial video, and Safe Sleep Summits have involved caregivers, healthcare providers, and community partners. Outcomes of this ongoing collaboration demonstrate a decrease in sleep-related infant mortality rates. Our findings also highlight the need for continued, real time monitoring of sleep-related infant mortality trends with a coordinated, multidisciplinary, and crossjurisdictional response. This initiative can serve as a model of cross-sector communication that can be replicated in other similar geographic locations to further reduce SUID.

Unexplained Infant Deaths Without Unsafe Sleep Factors: 2011 to 2020.

To describe sudden unexpected infant deaths (SUIDs) occurring in safe sleep environments and explore differences in selected characteristics. We examined SUID from 22 jurisdictions from 2011 to 2020 and classified them as unexplained, no unsafe sleep factors (U-NUSF). Data were derived from the Sudden Unexpected Infant Death and Sudden Death in the Young Case Registry, a population-based Centers for Disease Control and Prevention surveillance system built on the National Center for Fatality Review and Prevention's child death review program. SUID classified as U-NUSF included infants who were (1) awake, under supervision, and witnessed to become unresponsive or (2) found unresponsive in a safe sleep environment after sleep (unwitnessed). We calculated frequencies and percentages for demographics, birth and environmental characteristics, medical history, and death investigation findings. Most of the 117 U-NUSF SUID occurred before 4 months of age. Witnessed deaths most commonly occurred at <1 month of age (28%), whereas unwitnessed deaths most commonly occurred at ages 2 to 3 months (44%) Among all U-NUSF, 69% occurred in the infant's home (62% witnessed, 77% unwitnessed). All unwitnessed deaths occurred in a crib; most witnessed deaths occurred while being held (54%) or in a car seat traveling (18%). Most infants (84%) had no history of abuse or neglect. Abnormal autopsy findings were reported in 46% of deaths (49% witnessed, 42% unwitnessed). Characterizing these deaths is key to advancing our knowledge of SUID etiology. Our study revealed a heterogeneous group of infants, suggesting physiologic, genetic, or environmental etiologies.

Evaluating Educational Patterns and Methods in Infant Sleep Care: Trends, Effectiveness, and Impact in Home Settings—A Systematic Review

Background: Sleep care is crucial for the health and development of infants, with proper sleep patterns reducing the risk of sudden infant death syndrome (SIDS) and other sleep-related incidents. Educational interventions targeting caregivers are essential in promoting safe sleep practices. Methods: This systematic review adhered to PRISMA guidelines, searching databases such as PubMed, MEDLINE, Scopus, and the Cochrane Library. Inclusion criteria focused on studies involving home-based interventions for infants aged 0–12 months, including parental education and behavioral interventions. Exclusion criteria included studies in clinical settings and non-peer-reviewed articles. Data extraction and synthesis were performed by two independent reviewers, using a narrative approach to categorize interventions and outcomes. Results: Twenty-three studies met the inclusion criteria. Key findings indicate that home-based educational interventions, including hospital-based programs, home visits, and mobile health technologies, significantly improve parental knowledge and adherence to safe sleep practices. These interventions also enhance parental satisfaction and contribute positively to infant health outcomes. Conclusions: Educational interventions have demonstrated effectiveness in promoting safe sleep practices among caregivers, particularly in home settings. These interventions, including hospital-based programs, home visits, and digital tools, improve parental knowledge, adherence to guidelines, and overall satisfaction. The impact is evident in the reduction of unsafe sleep behaviors and enhanced infant health outcomes. However, variability in the intervention methods and delivery, cultural contexts, and geographic focus suggest a need for more tailored, long-term, and comprehensive studies. Future research should standardize outcome measures and assess the sustained impact of these educational strategies on infant sleep patterns and caregiver practices over time. This will provide deeper insights into the trends and long-term effectiveness of educational patterns and methods in diverse home environments.

Community partnership approaches to safe sleep (CPASS) program evaluation

BackgroundSudden unexpected infant death (SUID) continues to be a leading cause of death in infants in the United States (US), with significant disparities by race and socio-economic status. Infant safe sleep behaviors are associated with decreasing SUID risk, but challenges remain for families to practice these routinely. The objective of this program was to implement and evaluate a novel approach for an infant safe sleep pilot program built upon partnerships between hospitals and community-based organizations (CBOs) serving pregnant and parenting families in at-risk communities.MethodsCommunity Partnership Approaches to Safe Sleep (CPASS) was a prospectively implemented infant safe sleep program. CPASS included children’s hospitals partnered with CBOs across five US cities: Portland, OR, Little Rock AR, Chicago, IL, Birmingham, AL, and Rochester, NY. The program consisted of (1) monthly learning community calls; (2) distribution of Safe Sleep Survival Kits; and (3) surveys of sites and families regarding program outcomes. Survey measures included (1) site participation in CPASS activities; (2) recipients’ use of Safe Sleep Kits; and (3) recipients’ safe sleep knowledge and behaviors.ResultsCPASS learning community activities were consistently attended by at least two representatives (1 hospital-based, 1 CBO-based) from each site. Across the five sites, 1002 safe kits were distributed over 9 months, the majority (> 85%) to families with infants ≤ 1 month old. Among participating families, 45% reported no safe sleep location before receipt of the kit. Family adherence to nighttime safe sleep recommendations included: (1) no bedsharing (M 6.0, SD 1.8, range 0–7); (2) sleep on back (M 6.3, SD 1.7, range 0–7); and (3) sleep in a crib with no blankets/toys (M 6.0, SD 2.0, range 0–7). Site interviews described how participation in CPASS influenced safe sleep conversations and incorporated local data into counseling. Hospital-CBO relationships were strengthened with program participation.ConclusionsThe CPASS pilot program provides a new, innovative model built on hospital-community partnerships for infant safe sleep promotion in SUID-impacted communities. CPASS reached families before their infant’s peak age risk for SUID and empowered families with knowledge and resources to practice infant safe sleep. Important lessons learned included improved ways to center and communicate with families.

The risk of sleep-related death in an inclined sleep environment

BackgroundUnsafe sleep environments are the primary modifiable risk factor for sudden unexpected infant death (SUID). Despite this knowledge, products that deviate from the American Academy of Pediatrics (AAP) safe sleep recommendations continue to be commonplace, such as inclined sleepers. Analyses to estimate risk among these products are lacking, perpetuating their presence in the marketplace. We present a method of comparing risk of SUID in an inclined sleeper to an AAP-recommended sleep environment.MethodsA case-control analysis using publicly available and previously published survey data was conducted for SUID events occurring between January 1, 2018 and April 12, 2019 (the date of the first inclined sleeper recall). SUID deaths were categorized as occurring in an AAP-recommended sleep environments or in an inclined sleeper. Exposure Odds Ratios (OR) are reported as the risk of SUID among infants using inclined sleepers relative to an AAP-recommended sleep environment.ResultsDuring the study period, 4,900,573 births and 4,363 SUID deaths occurred in the US. Control characteristics were similar between previous night users of an AAP-recommended sleep environment (24%) and inclined sleepers (3.8%). Inclined sleepers were associated with a 5-fold (OR: 5.1; 95% CI: 3.2, 7.9) increased risk of SUID among infants < 12 months compared to infants in an AAP-recommended sleep environment. This risk was greatest among infants ≥ 4 months (RR: 10.4; 95% CI: 5.1, 21.5).ConclusionsThis novel analysis fills a longstanding gap in risk assessments of inclined infant sleep products. More timely risk analyses may improve the safety of the marketplace.

Best evidence summary of sleep protection in premature infants in the neonatal intensive care unit: a narrative review.

Sleep influences the interaction between infants and their environment, as well as the achievement of crucial milestones in motor and language development. This is particularly significant for preterm infants in vulnerable positions. However, prematurely born infants in the neonatal intensive care unit (NICU) are exposed to various stimuli such as noise and light, which disrupt their normal sleep patterns. This study assesses and consolidates the existing evidence on non-pharmacological strategies for protecting and promoting sleep in preterm infants. By providing an evidence-based data repository, it offers a valuable reference for clinical interventions. We conducted computer-based searches using various databases and resources, including UpToDate, BMJ Best Practice, Guidelines International Network (GIN), National Institute for Health and Clinical Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), National Guideline Clearinghouse (NGC), Registered Nurses Association of Ontario (RNAO), Joanna Briggs Institute (JBI), World Health Organization (WHO), Cochrane Library, Web of Science, PubMed, China National Knowledge Infrastructure (CNKI), Wanfang Data, and China Biology Medicine disc (CBM). The search period spanned from January 2014 to May 2024. We have included a total of 22 articles in our review, comprising two guidelines, 11 systematic reviews, 1 evidence summary, 1 technical report, 2 practice recommendations, and 5 randomized controlled trials. The evidence was synthesized from eight domains: sleep team construction, risk factor assessment, sleep assessment tools, positional management, noise control, light management, sensory stimulation, and hospital-home transition sleep management, resulting in 27 pieces of evidence. This study summarizes the optimal evidence for the management of sleep in premature infants, providing empirical support for standardizing the management of sleep in premature infants. It is recommended that healthcare professionals judiciously apply the best evidence while considering the clinical context, thus promoting safe sleep for premature infants.

When to sleep and consume caffeine to boost alertness.

Sleep loss can cause cognitive impairments that increase the risk of mistakes and accidents. However, existing guidelines to counteract the effects of sleep loss are generic and are not designed to address individual-specific conditions, leading to suboptimal alertness levels. Here, we developed an optimization algorithm that automatically identifies sleep schedules and caffeine-dosing strategies to minimize alertness impairment due to sleep loss for desired times of the day. We combined our previous algorithms that separately optimize sleep or caffeine to simultaneously identify the best sleep schedules and caffeine doses that minimize alertness impairment at desired times. The optimization algorithm uses the predictions of the well-validated Unified Model of Performance to estimate the effectiveness and physiological feasibility of a large number of possible solutions and identify the best one. To assess the optimization algorithm, we used it to identify the best sleep schedules and caffeine-dosing strategies for four studies that exemplify common sleep-loss conditions and compared the predicted alertness-impairment reduction achieved by using the algorithm's recommendations against that achieved by following the U.S. Army caffeine guidelines. Compared to the alertness-impairment levels in the original studies, the algorithm's recommendations reduced alertness impairment on average by 63%, an improvement of 24 percentage points over the U.S. Army caffeine guidelines. We provide an optimization algorithm that simultaneously identifies effective and safe sleep schedules and caffeine-dosing strategies to minimize alertness impairment at user-specified times.

Promoting Safe Sleep: The Role of Doulas in Black Communities

BackgroundAccidental suffocation and strangulation in bed continues to be a critical issue in Black communities, despite the widespread initiatives to promote safe sleep. Doulas are in an ideal position to promote safe sleep, particularly in hard-to-reach communities that are more distrusting of conventional medical providers. Little is known about their practices and perspectives for putting infants down to rest. This study informs this gap in the literature.PurposeThe purpose of this study was to explore doulas’ perspectives and practices in the field of putting infants down to sleep. The researchers aimed to determine whether Black caregivers that work with doulas are likely to encounter safe sleep education.MethodsThe researchers used a descriptive approach to inquiry. They conducted three focus groups with a total of 17 Black doulas. The researchers independently and critically reviewed the transcriptions and observation notes from each group to identify codes. They then triangulated the results using Artificial Intelligence-driven tools.FindingsThe study found four themes: (1) Individualized Services, (2) Cultural Sensitivity, (3) Negotiating Safety, and (4) Safe Sleep Education.ConclusionsThe study concluded doulas have a commitment to promoting safe sleep. The researchers found that doulas engage in practices that help caregivers to integrate safe sleep practices into their lifestyle and to adapt them to meet their needs. The researchers also documented a desire for more information and instruction on safe sleep among practicing doulas.

Educational Boost Slashes SIDS Risk Awareness Gap Among Nurses in Iraq

This study evaluates the impact of an educational program on nurses' knowledge of Sudden Infant Death Syndrome (SIDS) risk factors at pediatric teaching hospitals in Baghdad City. Using a quasi-experimental design with fifty nurses divided into a control and a research group, we assessed knowledge levels through pre-tests and two post-tests. Results indicated that the educational intervention significantly improved nurses' knowledge from 60% to 76%, although this effect diminished slightly over time. The study underscores the importance of continuous education in enhancing nurse awareness and the implementation of safe sleep practices to reduce SIDS occurrences. Highlights: Educational Impact: The study demonstrates a significant increase in nurses' knowledge about SIDS risk factors following an educational intervention. Sustained Learning: Knowledge gains were observed to diminish slightly over time, highlighting the need for ongoing educational programs. Practical Implications: Enhanced nurse training supports safer sleep practices, potentially reducing the incidence of SIDS.

Implementing a Safe Sleep Shelter and Baby Bundle Kit Distribution Program.

The Georgia Department of Public Health developed the Safe Sleep Shelter Program to expand Georgia Safe to Sleep campaign efforts. The program focused on engaging with housing support agencies, homeless shelters, and domestic violence shelters. The program offered a menu of resources that agencies could choose from, including portable cribs for agency use and distribution to families, safe sleep education for staff, assistance with creating/updating agency safe sleep policies, and Baby Bundle Safe Sleep kits with education and resources for families. The program showed promising results: 44 agencies across the state applied, serving an estimated 20,950 individuals annually. Agencies expressed strong interest in expanding safe sleep education and resources for the families they served. Most agencies reported that the program filled gaps in services, including having enough cribs to meet demand and limited safe sleep education and resources. Agencies reported that parents appreciated the cribs and Baby Bundle Safe Sleep kits as most did not have money to purchase an infant sleep surface. Agencies reported that the resources provided new information to infant parents, facilitated discussion, and reinforced safe sleep messaging. Evaluation challenges included difficulties collecting distribution data and a low response rate for parent surveys. Implications are discussed for others interested in implementing such a program, including to develop processes for communicating updated recommendations, leverage existing relationships to engage additional agencies, evaluate efforts to refine program components, and consider strategies to increase parent survey response rates.

Factors Associated with Breastfeeding Initiation and Continuation at Two Months Postpartum in American Indian Women: An Exploratory Analysis.

This study aimed to determine the prevalence of breastfeeding initiation and continuation at two months postpartum in American Indian (AI) mothers in South Dakota and to identify factors associated with breastfeeding. Using logistic regression, data from the South Dakota Pregnancy Risk Assessment Monitoring System were used to investigate the relationship between binary breastfeeding initiation and continuation outcomes and maternal behaviors and experiences including access to health care, safe sleep practices, ability to handle life events, depression, and sources of breastfeeding information. Higher odds of initiation were seen for factors including access to health care services, ability to handle life events, and sources of breastfeeding information, while lower odds were seen for factors including safe sleep. Higher odds of continuation were seen among mothers who reported not taking long to get over setbacks and among mothers who reported no postpartum depression, while lower odds of continuation were seen among mothers practicing safe sleep. Several modifiable factors were identified as reasons for stopping breastfeeding. This information about factors associated with higher odds of breastfeeding initiation and continuation at two months postpartum can be used to inform interventions, programs, and policies designed to support breastfeeding among AI women and to guide future research in this area.

Photos Shared on Facebook in the Context of Safe Sleep Recommendations: Content Analysis of Images.

Sudden unexpected infant death (SUID) remains a leading cause of infant mortality; therefore, understanding parental practices of infant sleep at home is essential. Since social media analyses yield invaluable patient perspectives, understanding sleep practices in the context of safe sleep recommendations via a Facebook mothers' group is instrumental for policy makers, health care providers, and researchers. This study aimed to identify photos shared by mothers discussing SUID and safe sleep online and assess their consistency with infant sleep guidelines per the American Academy of Pediatrics (AAP). We hypothesized the photos would not be consistent with guidelines based on prior research and increasing rates of accidental suffocation and strangulation in bed. Data were extracted from a Facebook mothers' group in May 2019. After trialing various search terms, searching for the term "SIDS" on the selected Facebook group resulted in the most relevant discussions on SUID and safe sleep. The resulting data, including 20 posts and 912 comments among 512 mothers, were extracted and underwent qualitative descriptive content analysis. In completing the extraction and subsequent analysis, 24 shared personal photos were identified among the discussions. Of the photos, 14 pertained to the infant sleep environment. Photos of the infant sleep environment were then assessed for consistency with safe sleep guidelines per the AAP standards by 2 separate reviewers. Of the shared photos relating to the infant sleep environment, 86% (12/14) were not consistent with AAP safe sleep guidelines. Specific inconsistencies included prone sleeping, foreign objects in the sleeping environment, and use of infant sleeping devices. Use of infant monitoring devices was also identified. This study is unique because the photos originated from the home setting, were in the context of SUID and safe sleep, and were obtained without researcher interference. Despite study limitations, the commonality of prone sleeping, foreign objects, and the use of both infant sleep and monitoring devices (ie, overall inconsistency regarding AAP safe sleep guidelines) sets the stage for future investigation regarding parental barriers to practicing safe infant sleep and has implications for policy makers, clinicians, and researchers.

Sleeping Safe and Sound: A Multidisciplinary Hospital-wide Infant Safe Sleep Quality Improvement Initiative

IntroductionPromoting Safe Sleep to decrease sudden unexpected infant death is challenging in the hospital setting. Local ProblemConcern for adherence to Safe Sleep practice across inpatient units at a large pediatric hospital. MethodsUtilized Quality improvement (QI) methodologies to promote Safe Sleep across all units. InterventionsDevelopment of a multidisciplinary expert group, hospital-wide guidelines, targeted interventions, and bedside audits to track progress. ResultsAdherence to Safe Sleep practices improved from 9% to 53%. Objects in the crib were a major barrier to maintaining a Safe Sleep environment. Safe Sleep practices were less likely to be observed in infants with increased medical complexity (p=.027). ConclusionsQI methodology improved adherence to infant Safe Sleep guidelines across multiple units. Medically complex infants continue to be a challenge to Safe Sleep. Therefore, ongoing education for staff and further research into best practices for the most complex infant populations are necessary.

Sleep and Mood Among Women With Histories of Depression When They Used a Responsive Infant Bassinet During the COVID-19 Pandemic

ObjectiveTo describe the experiences of women with histories of depression who used a responsive infant bassinet during the first 6 months after birth during the COVID-19 pandemic. DesignSecondary qualitative descriptive study with analytic expansion. SettingUnited States. ParticipantsWomen (N = 139) who gave birth up to 6 months previously and had histories of depression. MethodsWe used Kyngäs’s method of inductive content analysis to analyze 109 open-ended responses that were collected between August 2020 to November 2021 as part of a previously conducted longitudinal study of women who used a responsive bassinet. ResultsMost participants indicated that the responsive bassinet improved their infants’ sleep, which, in turn, subjectively improved their sleep and mood. External stressors and challenges presented barriers to good sleep for the participants and their infants, and participants described how these challenges contributed to their symptoms related to mood. When participants reported that they used the responsive bassinet, they shared that their infants were swaddled in the supine sleep position. Participants who did not use the bassinet commonly reported unsafe sleep practices. We identified seven themes from the data: Improved Maternal Sleep Quality, Barriers to Good Maternal Sleep, Mood and Sleep Go Hand and Hand, External Stressors Impair Mood, Improved Infant Sleep Quality, Barriers to Good Infant Sleep, and Safe Sleep Positioning. ConclusionThese findings can be used to inform clinicians on how a responsive bassinet may offer women at high risk for postpartum depression improved sleep and instrumental support. Future researchers should use validated measures to objectively evaluate rates of postpartum depression and sleep quality in high-risk women when using a responsive bassinet.

The Tension Between AAP Safe Sleep Guidelines and Infant Sleep.

To understand tension mothers experience when attempting to follow American Academy of Pediatrics safe sleep guidelines and enhancing infant and parental sleep. Surveys and focus groups were conducted from November 2022 and March 2023 with United States-based English-speaking mothers of infants <6 months of age recruited via social media and who reported a nonrecommended sleep position and/or location ≥2 times the prior week. Twenty-five mothers participated in focus groups and surveys. A total of 80% reported holding or rocking their infant to sleep; 76% fed their infant to sleep. Almost all were aware of the ABCs (Alone, Back, Crib) of safe sleep and intended to follow them before delivery. Many felt that ABCs were unrealistic and placed their infants in nonrecommended locations or positions because they perceived them as more comfortable and helping their infant fall and stay asleep. Mothers were more likely to use nonrecommended practices when they were awake or sleeping nearby and believed they could closely monitor their infant. Some questioned whether ABCs were the only way to achieve safe sleep. Some prioritized other safety concerns (eg, fall prevention) over sudden infant death syndrome or sudden unexpected infant death prevention. Mothers expressed confidence about getting their baby to sleep in general but were less confident that they could do this while following guidelines. Despite awareness of the ABCs, mothers regularly engaged in nonrecommended practices with the goal of improving their own and their infant's sleep. Interventions focused on improving infant and parental sleep while maintaining sleep safety are needed.

The Relation of Maternal Psychosocial Risk Factors to Infant Safe Sleep Practices.

Sleep-related infant deaths are a common and preventable cause of infant mortality in the United States. Moreover, infants of color are at a greater risk of sleep-related deaths than are White infants. The American Academy of Pediatrics (AAP) published safe sleep guidelines to minimize the number of sleep-related infant deaths; however, many families face barriers to following these guidelines. Research on the role of psychosocial risk factors (i.e., depression, stress, domestic violence, substance use) in mothers' engagement in safe sleep practices is limited. The present study examined the role of maternal psychosocial risk factors on maternal safe sleep practices and the moderating effects of maternal race on this relationship. Participants in this study were mothers (N = 274) who were recruited from a Midwestern hospital postpartum. Data on the participants' psychosocial risk factors, and safe sleep practices were collected via telephone interview 2-4months following the birth of their infant. Predictive models indicated that depression and stress impacted mothers' engagement in following the safe sleep guidelines. Specifically, higher levels of maternal depression predicted greater likelihood of co-sleeping, regardless of mothers' race. Higher levels of maternal stress also predicted lower engagement in safe sleep behaviors for White mothers only. Early interventions to address stress and depression may help to increase maternal adherence to the AAP's safe sleep guidelines. Additional research on the underlying mechanisms of depression and stress on maternal safe sleep engagement is needed.

Characteristics of Sudden Unexpected Infant Deaths on Shared and Nonshared Sleep Surfaces.

Describe characteristics of sudden unexpected infant deaths (SUID) occurring on shared or nonshared sleep surfaces. We examined SUID among residents of 23 US jurisdictions who died during 2011 to 2020. We calculated frequencies and percentages of demographic, sleep environment, and other characteristics by sleep surface sharing status and reported differences of at least 5% between surface sharing and nonsharing infants. Of 7595 SUID cases, 59.5% were sleep surface sharing when they died. Compared with nonsharing infants, sharing infants were more often aged 0 to 3 months, non-Hispanic Black, publicly insured, found supine, found in an adult bed or chair/couch, had a higher number of unsafe sleep factors present, were exposed to maternal cigarette smoking prenatally, were supervised by a parent at the time of death, or had a supervisor who was impaired by drugs or alcohol at the time of death. At least 76% of all SUID had multiple unsafe sleep factors present. Among surface-sharing SUID, most were sharing with adults only (68.2%), in an adult bed (75.9%), and with 1 other person (51.6%). Surface sharing was more common among multiples than singletons. Among SUID, surface sharing and nonsharing infants varied by age at death, race and ethnicity, insurance type, presence of unsafe sleep factors, prenatal smoke exposure, and supervisor impairment. Most SUID, regardless of sleep location, had multiple unsafe sleep factors present, demonstrating the need for comprehensive safe sleep counseling for every family at every encounter.
