Sudden Infant Death Syndrome (SIDS) risk reduction and infant sleep location – Moving the discussion forward

"Things changed very quickly": Maternal intentions and decision-making about infant sleep surface, location, and position

INTRODUCTION

Approximately 3400 infants die suddenly and unexpectedly each year in the United States; many of these deaths include modifiable risk factors (such as a non-supine position, sleeping on a soft surface, or loose bedding or items in the environment). Interventions have been successful at improving parental knowledge about recommendations to reduce risk of sleep-related infant deaths, as well as improving intention to adopt recommendations. However, follow-up studies have found a disconnect between knowledge/intentions to adhere to recommendations and actual practices. Exploring maternal decision-making about infant sleep practices can better elucidate the disconnect between knowledge of infant sleep recommendations and the practice of it, and thus, inform more effective safe sleep interventions. The purpose of this study was to gain a more in-depth understanding of decision-making around infant sleep practices, and barriers and facilitators to adopting safe infant sleep recommendations.

METHODS

Semi-structured in-home interviews were conducted with 22 families (20 mothers and 2 mother-father dyads) of infants up to 6 months of age.

RESULTS

Thematic analysis of the transcripts revealed six themes: Plans changed when baby came, Trying things to figure out what works (infant preferences), Safety concerns, What's comfortable for me (maternal preferences), They say…(advice), and Trying to be careful.

CONCLUSION

These results suggest that knowledge of infant sleep recommendations alone is not enough to ensure adherence and that decision-making is a dynamic and ongoing process affected by multiple factors. Findings have implications for timing and content of risk reduction efforts, as well as for data collection in research studies.

Implementation of safe infant sleep recommendations during night-time sleep in the first year of life in a German birth cohort

The aim of our study was to assess the extent to which families followed recommendations, issued by the German society for sleep medicine, for the prevention of sudden infant death syndrome (SIDS) during night-time sleep. Analyzing longitudinal data from a birth cohort located at the University Children's Hospital Regensburg in Bavaria (Germany), we determined data regarding the infant's sleep location, sleep settings and body position, and exposure to environmental factors. Data were collected in a structured interview after birth and by standardized questionnaires at 4 weeks, 6 months, and 1 year of life, respectively. The majority of 1,400 surveyed infants (94% at 4 weeks) were reported to sleep in the parents' sleeping room during the first months of life. While the most common furniture was a bedside sleeper (used by 48%), we also observed a considerable proportion of families who regularly practiced bed-sharing and, for 16% of infants, the parents' bed was the default sleeping place. 12% of infants were still put regularly in the prone position. The vast majority (87%) of the infants were breastfed at some timepoint and 17% lived in a household with one or more smokers. Although most parents implemented many SIDS recommendations, our analysis illustrates a considerable gap between recommendations and intentions after birth on the one hand and actual implementation in real life on the other. The number-one deviation from the current SIDS guidelines during night-time sleep was bed-sharing with an adult.

Links between household and family social dynamics with sleep profiles among BaYaka foragers of the Congo Basin

Given the contributions of sleep to a range of health outcomes, there is substantial interest in ecological and environmental factors, including psychosocial contexts, that shape variation in sleep between individuals and populations. However, the links between social dynamics and sleep are not well-characterized beyond Euro-American settings, representing a gap in knowledge regarding the way that local socio-ecological conditions interrelate with sleep profiles across diverse settings. Here, we focused on data from a subsistence-level society in Republic of the Congo to test for links between the household/family social environment and sleep measures. Specifically, we used actigraphy-derived sleep data (N = 49; 318 nights) from two community locations (a village and rainforest camp) among BaYaka foragers, who are members of a remote, non-industrialized subsistence society in the Congo Basin. We drew on social dynamics that have been previously linked to sleep variation in Euro-American contexts, including: household crowding, same surface cosleeping, and marital conflict. We examined the following sleep measures: total sleep time (TST), total 24-h sleep time (TTST), and sleep quality (fragmentation). BaYaka adults had shorter and lower quality sleep when their shared sleeping space was more crowded. In the village, parents with breastfeeding-aged infants had longer TTST and higher quality sleep than adults without infants, contrasting with results from other cultural contexts. Based on peer rankings of marital conflict, husbands showed longer and higher quality sleep in less conflicted marriages. Women showed the opposite pattern. These counter-intuitive findings for women may reflect the limitations of the measurement for wives' marital experiences. In total, these results point to the importance of considering local socio-ecological conditions to sleep profiles and underscore the need for expanded study of sleep and health outcomes in settings where shared sleep in constrained space is routine practice.

Infant Care Practices, Caregiver Awareness of Safe Sleep Advice and Barriers to Implementation: A Scoping Review

Modifiable infant sleep and care practices are recognised as the most important factors parents and health practitioners can influence to reduce the risk of sleep-related infant mortality. Understanding caregiver awareness of, and perceptions relating to, public health messages and identifying trends in contemporary infant care practices are essential to appropriately inform and refine future infant safe sleep advice. This scoping review sought to examine the extent and nature of empirical literature concerning infant caregiver engagement with, and implementation of, safe sleep risk-reduction advice relating to Sudden Unexpected Deaths in Infancy (SUDI). Databases including PubMed, CINAHL, Scopus, Medline, EMBASE and Ovid were searched for relevant peer reviewed publications with publication dates set between January 2000–May 2021. A total of 137 articles met eligibility criteria. Review results map current infant sleeping and care practices that families adopt, primary infant caregivers’ awareness of safe infant sleep advice and the challenges that families encounter implementing safe sleep recommendations when caring for their infant. Findings demonstrate a need for ongoing monitoring of infant sleep practices and family engagement with safe sleep advice so that potential disparities and population groups at greater risk can be identified, with focused support strategies applied.

Association Between Infant Sleep Location and Breastfeeding

Objective: Studies have shown that mothers sleeping with their babies have longer breastfeeding duration. Bedsharing (BS) is thought to be a risk factor for Sudden Infant Death Syndrome. The aim was to investigate the frequency of BS and roomsharing (RS) and the effect of those on breastfeeding during the first 2 years of life. Also to evaluate risk-bearing situations regarding sleep environment. Methods and Study Design: This is a cross-sectional study, with retrospective cohort features for the evaluation of some data. The setting was a Well-Child Clinic at Bakırköy Research and Training Hospital. The children were followed from the first month until survey. Feeding history was collected retrospectively from child health records. Parents were surveyed concerning sleeping location and sleeping arrangements with a questionnaire. The study encompassed 351 children and their families. Results: The rate of exclusive breastfeeding was found to be 50.2% for the first 6 months of life and BS increased in exclusively breastfed infants. When breastfeeding continued after 6 months, the trend of increased BS through months was observed. RS, BS, and breastsleeping rates were 80.6%, 22.8%, 56.1%, respectively, in the whole cohort. Working mothers and mothers >35 years of age were significantly more likely to bedshare. Cigarette smoking in BS parents was identified as a child health risk. Unsafe sleep environment was found in 72.4% of the group. Conclusions: BS increases breastfeeding for the first 6 months. Families need guidance on safe sleeping practices and should be advised regarding avoidable risks and unsafe situations in BS. Parents should be counseled to make informed decisions.

Epidemiology of sudden infant death syndrome in Mexico, 2005-2020

BACKGROUND

Sudden Infant Death Syndrome (SIDS) constitutes one of the main causes of mortality in children under one year of age in developed countries; it's frequency to varies geographically. In Mexico the real incidence of SIDS is not known.

METHODS

National databases of deaths in children under one year of age, from 2005 to 2020, were analyzed, due to Sudden Unexpected Infant Death (SUID) [SIDS (R95), accidental suffocation in a sleeping environment (W75), and other ill-defined and unspecified causes of mortality (R99), according to the International Classification of Diseases, tenth revision (ICD 10)]. Mortality rates per year of occurrence due to SUID and their subcategories were calculated. Simple frequencies of SIDS were obtained per year and month of occurrence, state of residence, age, place of death, and access to social security services.

RESULTS

In the study period 473,545 infant deaths occurred; 7,714 (1.62%) deaths were due to SUID; of these, 6,489 (84%) were due to SIDS, which is among the 10 leading causes of infant death in Mexico. The average mortality rate for SUID was 22.4/100,000 live births, for SIDS was 18.8/100,000 live births. Mortality rates within the states were variable, ranging from 2.4/100,000 to 105.1/100,000 live births. In 81% of SIDS records there was no autopsy; 38% of deaths due to SIDS occurred in infants under one month of age, up to 87% of deaths occurred in families without social security services or it was unknown, and 76.2% of deaths occurred at home. Deaths were more frequent during the last months of autumn and during winter.

CONCLUSION

In Mexico there is an underregistry of SIDS as cause of death, along with other SUID categories. Health workers need to be trained to improve diagnosis and data registration, including the practice of autopsies; additionally, it is necessary to implement a public health campaign.

Pēpē-infant sleep practices and sudden unexpected death in infancy in Aotearoa New Zealand

OBJECTIVE

To explore pēpē [infant] sleep practices and the key motivators among selected Māori and non-Māori māmā [mothers] in Auckland, New Zealand, in relation to the risk of sudden unexpected death in infancy (SUDI).

METHODS

Qualitative research underpinned by a kaupapa Māori cultural framework was undertaken. In-depth face-to-face interviews occurred in the homes of māmā with young pēpē born in Counties Manukau, Auckland. Interview transcripts were analyzed using general purpose thematic analysis.

RESULTS

Thirty māmā participated, including 17 Māori. Two-thirds of māmā reported previous or current bed sharing. The fundamental human need for adequate sleep motivated half the māmā in the present study, and especially Māori māmā, to bed share. The second most common reason given was closeness and convenience. This was followed by breastfeeding, which was cited as a reason by Māori māmā only. These findings were interpreted in terms of intrinsic fear, culture, and māmā deployment of knowledge.

CONCLUSION

Service providers are encouraged to respond to the lived experiences and cultural realities, values, and beliefs of māmā when designing and delivering effective SUDI prevention interventions. Innovative approaches for providing structured and opportunistic, culturally appropriate education and support around safe sleep are likely to be well-received by māmā and their whānau [family/ies].

Evaluation of a Multisite Safe Infant Sleep Education and Crib Distribution Program

Rates of sleep-related infant deaths have plateaued in the past few decades despite ongoing infant sleep practice recommendations to reduce risk of sleep-related infant deaths by the American Academy of Pediatrics. The state department of public health trained facilitators at 28 sites across the state to facilitate a group safe sleep educational program. A prospective, matched pre- and post-test cohort design with follow-up was used to evaluate changes in self-reported knowledge, intentions, and practices. The final sample included 615 matched pre- and post-test surveys, and 66 matched follow-up surveys. The proportion of correct responses on all knowledge and intended practice items increased significantly from pre- to post-test. When asked where their babies would have slept if they had not received the portable crib, 66.1% of participants planned to use a recommended sleep location (e.g., crib or bassinet). At post-test, 62.3% planned to change something about their infant’s sleep based on what they learned. At follow-up, knowledge was maintained for all but two items and practices and for half of practice items. The results suggest that participating in the education program was associated with increased knowledge and intended adherence, but that these changes were not maintained at follow-up. These results are in line with the research literature that finds a difference in intentions and actual practices after the baby is born.

'It looks like a breadbox': a pilot study investigating implementation of the Pepi-Pod® program with Aboriginal families in metropolitan South Australia

AIMS

To collaboratively explore the cultural acceptance of the Pepi-Pod® program as an alternate safe sleep space and to explore the process of implementing the Pepi-Pod® program in a mainstream health service for Aboriginal families living in urban South Australia.

BACKGROUND

Aboriginal and Torres Strait Islander infants continue to die from sudden infant death syndrome (SIDS) and sudden unexpected death in infancy (SUDI) at rates three to four times greater than other infants born in Australia despite Council of Australian Governments commitment to halve the gap in the Indigenous infant mortality rate by 2018. The Pepi-Pod® program is evidenced in New Zealand and Queensland to provide a culturally appropriate safe sleep alternative that contributes to the reduction of SIDS and SUDI. We have no evidence of acceptability or feasibility when offered through mainstream services in metropolitan South Australia.

METHODS

With a focus on decolonizing the research process through a two-way process for mutual learning between Aboriginal and non-Aboriginal team members and community, a novel qualitative design was employed including photo elicited yarning sessions (n = 7), focus groups (n = 2), and field notes (n = 15).

RESULTS

Four themes emerged: 'you don't have to worry'; 'a way of sharing knowledge'; 'it looks like a bread box?' and 'need for consistent safe sleep messages'. The findings suggest that participants believe the Pepi-Pod® program may enrich Aboriginal families' lives evoking feelings of comfort and safety; however, the design could be improved to make them more culturally appropriate. There was confusion around safe sleep processes and education with a call for streamlining safe sleep messaging.

Feasibility and Acceptability of a Tailored Infant Safe Sleep Coaching Intervention for African American Families

Background: Approximately 3600 infants die suddenly and unexpectedly annually in the United States. Research suggests limitations of current behavioral interventions to reduce the risk for sleep-related deaths among African American families living in under-resourced neighborhoods. Guided by the theory of planned behavior and the socio-ecological model, the My Baby’s Sleep (MBS) intervention intends to reduce the risk for sleep-related infant deaths while addressing complex needs of African American families living in under-resourced neighborhoods. Objective: To assess feasibility and acceptability of MBS, a 7-month intervention that includes four home visits and multiple check-ins via phone and text message. Methods: This was a single-arm feasibility and acceptability study with quantitative and qualitive measures. African American families were recruited from community agencies that served an under-resourced metropolitan area. Results: Eight families (eight mothers, nine co-caregivers) completed the intervention. Families reported high acceptability of MBS content, process, and format, as evidenced by qualitative data and mean evaluation scores. Conclusion: MBS is feasible and acceptable among African American families living in under-resourced neighborhoods. These results suggest further investigation of MBS intervention efficacy in a large-scale randomized controlled trial.

Are Safe Sleep Practice Recommendations For Infants Being Applied Among Caregivers?

Background

Sudden infant death syndrome (SIDS) is defined as the sudden unexpected death of an infant, even after investigations and autopsy. SIDS is related to many factors, such as the baby’s position and objects in the crib. Adherence to safe sleep recommendations in Saudi Arabia is unclear. This study aims to assess caregivers’ implementation of safe sleep practices and if they received any safe sleep education through health care workers.

Methods

This was a cross-sectional, descriptive study. Inclusion criteria included all infants below the age of one year. Exclusion criteria included infants who were born premature, used ventilation, had a tracheostomy, any anomaly in the upper airway, or underwent spine surgery. A semi-structured questionnaire was used. Data were collected from mothers who had infants visiting the outpatient department of King Abdulaziz University Hospital in Jeddah, Saudi Arabia. An electronic survey was also created and published on a social platform. 

Statistical analysis was conducted with the aid of the Statistical Package for Social Sciences (SPSS) software, version 26 (IBM SPSS Statistics, Armonk, NY).

Results

Among 506 participants, only 22.5% were found to receive education about safe practices from health care providers. Fortunately, most of the infants (63.2%) were found to sleep in a supine position most of the nights. Adherent caregivers to placing the child in a designated baby bed and in a supine position most nights represented 44.86% of the sample. However, when asked about placing any of the following objects in the bed (pillows, blankets, soft toys, hard toys, and electric wires), the percentage of adherence dropped down to only 1.58%.

Conclusion

There was an obvious non-adherence among caregivers and a possible lack of knowledge of safe sleep recommendations for infants. This highlights the need for optimal education by health care workers and the rule of media and campaigns is obvious and essential to improving their practices and, hopefully, decreasing the risk of SIDS.

Back to the Breast: An Historical Overview of the Perceived Connections Between Sudden Infant Death Syndrome and Breastfeeding

In the late 19th century, physicians in the United States and Europe grew concerned about an increasingly visible subset of infant mortality: sudden infant death. Over the next 100 years, physicians worked variably to combat the problem, modifying and refining their conceptions of sudden infant mortality many times over the process. Physicians' overlapping revisions of sudden infant mortality ultimately helped to produce the categorization of Sudden Infant Death Syndrome (SIDS), and their ensuing, fluctuating efforts to resolve this problem shed light on social and medical perceptions of the roles that biology, the environment, and infant care practices played in sudden infant death. SIDS's official medical classification was a watershed; not only did the formal medical label establish its "authenticity" as a medical phenomenon, but the label also asserted the inexplicability of (at least some) sudden infant death episodes while simultaneously conveying that affected parents were deserving victims of a tragic loss. In the modern history of sudden infant death in the United States, breastfeeding, in particular, was understood variably as a possible cause for unnecessary infant mortality in the decades surrounding 1900; inconsequential to the occurrence of SIDS in the mid 1900s; and finally as an important and healthful way to reduce the risk for SIDS beginning in the late 1900s.

Breastfeeding Duration and Infant Sleep Location in a Cohort of Volunteer Breastfeeding Counselors

BACKGROUND

Debate about mother and infant bed sharing has been polarized between supporters of bed sharing and public health policies that attempt to mitigate the risk of Sudden Infant Death Syndrome. Differences in group demographics may be an important aspect in co-sleeping acceptability.

RESEARCH AIMS

The first aim of this study was to investigate infant sleeping location in a dataset of mothers with strong breastfeeding outcomes. The second aim was to investigate the association between infant sleeping location and breastfeeding (exclusive breastfeeding to 6 months and total breastfeeding duration). Finally, we aimed to investigate predictors of breastfeeding duration.

METHODS

Participants comprised 174 women who had applied to train as counselors with the Australian Breastfeeding Association. Data were compiled from a survey of the participants' lactation histories, including questions related to the exclusivity and duration of breastfeeding, concerns about and problems encountered during breastfeeding, type of birth, medications during birth, demographics, and infant sleeping location. The study design was a cross-sectional, one-group survey design.

RESULTS

A high proportion of participants in this study bed shared and room shared: At 0-1 month (n = 58), 33% of participants bed-shared, which increased to 58% by 6-12 months (n = 80). Infants who co-slept were more likely to be exclusively breastfed at 6 months (χ² (2, n = 116) = 4.83, p = .03) and had longer breastfeeding duration (t (62.61) = 3.81, p < .001).

CONCLUSIONS

Breastfeeding targets have been difficult to achieve globally, and innovative ideas are required to improve breastfeeding outcomes through public health messaging. There was a strong association in the current study between breastfeeding outcomes and degree of closeness of the infant to the mother at night. This finding should be brought into the discourse on breastfeeding and infant sleep arrangements, accompanied by evidence-based advice about safe sleeping and the promotion of breastfeeding.

Personalising Safe Sleep Messaging for Infant Caregivers in the United States

The purpose of our study was to better understand why parents/caregivers might not practice safe sleep behaviours. In autumn 2016, we conducted 'pulse' interviews with 124 parents/caregivers of children under the age of one year at a variety of local community events, festivals and meetings in cities with high infant mortality rates around the Midwestern US state of Ohio. Through an inductive approach, pulse interviews were analysed using thematic coding and an iterative process which followed for further clarification of themes (Qualitative Research in Psychology, 2006, 3, 77; BMC Medical Research Methodology, 2013, 13, 117). The six major themes of underlying reasons why parents/caregivers might not practice safe sleep behaviours that were identified in our coding process included the following: (a) culture and family tradition, (b) knowledge about safe sleep practices, (c) resource access, (d) stressed out parents, (f) lack of support and (g) fear for safety of baby. Using the descriptive findings from the pulse interviews, qualitative themes and key informant validation feedback, we developed four diverse fictional characters or personas of parents/caregivers who are most likely to practice unsafe sleep behaviours. These personas are characteristic scenarios which imitate parent and caregiver experiences with unsafe sleep behaviours. The personas are currently being used to influence development of health promotion and education programs personalised for parents/caregivers of infants less than one year to encourage safe sleep practices.

Infant care practices and parent uptake of safe sleep messages: a cross-sectional survey in Queensland, Australia

Background

Globally, the incidence of sleep-related infant mortality declined dramatically following the first public health campaigns seen internationally in the 1990s to reduce the risks of sudden infant death. However, Australian Sudden Unexpected Death in Infancy (SUDI) rates have plateaued with little change in incidence since 2004 despite two further public health safe sleep campaigns. This study aims to describe contemporary infant care practices employed by families related to the current public health SUDI prevention program.

Methods

A cross-sectional survey of 3341 Queensland primary caregivers with infants approximately 3-months of age was conducted using the Queensland Registry of Births, Deaths and Marriages as a sampling frame. Surveys were returned either via reply-paid mail or online. Questionnaires explored prevalence of infant care practices and awareness of safe sleep recommendations. Univariable analysis was used to generate descriptive statistics for key variables.

Results

Overall, only 13% of families routinely practised all six ‘Safe Sleeping’ program messages. More than one third (1118, 34%) of infants had slept in a non-supine sleep position at some time. Potentially hazardous sleep environments were common, with 38% of infants sleeping with soft items or bulky bedding, or on soft surfaces. Nearly half, for either day- or night-time sleeps, were routinely placed in a sleep environment that was not designed or recommended for safe infant sleep (i.e. a bouncer, pram, beanbag). Most babies (84%) were reportedly smoke free before and after birth. Sleeping in the same room as their caregiver for night-time sleeps was usual practice for 75% of babies. Half (1600, 50%) of all babies shared a sleep surface in the last two-weeks. At 8-weeks, 17% of infants were no longer receiving any breastmilk.

Conclusions

The prevalence rates of infant care practices among this Australian population demonstrate many families continue to employ suboptimal practices despite Australia’s current safe sleep campaign. Strategic approaches together with informed decisions about pertinent messages to feature within future public health campaigns and government policies are required so targeted support can be provided to families with young infants to aid the translation of safe sleep evidence into safe sleeping practices.

Prevalence and Predictors of Postpartum Maternal and Infant Bed-Sharing Among Chinese-Canadian Women

Objective/Background: Our primary objective was to describe and identify predictors of any and predominant bed-sharing at 4 and 12 weeks postpartum among Chinese-Canadian mothers. Participants: We conducted a longitudinal study of 570 Chinese immigrant and Canadian-born women in Toronto, Ontario. Methods: Any bed-sharing, defined as sharing a bed or mattress for any part of the night on any night in the previous week, and predominant bed-sharing, defined as sharing a bed or mattress for most of the night, on more than half the nights of the previous week, were evaluated at 4 and 12 weeks postpartum. Predictors of bed-sharing, evaluated in multivariable logistic regression models, were background (age, parity, education, household size, delivery mode, social support), cultural (immigrant status, acculturative stress, acculturation, postpartum ritual uptake), and postpartum variables (mental health, breastfeeding problems, fatigue, sleep knowledge, plans for bed-sharing, perceptions of infant sleep problems, cognitions about infant sleep). Results: One in five women (20.7%) reported bed-sharing as the predominant sleep location for their infant at 4 weeks postpartum, with nearly half (45.6%) reporting any bed-sharing at this time. The prevalence of any bed-sharing remained relatively stable at 12 weeks postpartum (46.5%), while predominant bed-sharing increased to 30.1%. The most consistent predictors of any and predominant bed-sharing at 4 and 12 weeks postpartum were lower education level, greater acculturative stress, and predelivery plans to bed-share. Conclusions: These findings have implications for the development of clinical recommendations given to expectant and new parents to promote infant sleep practices that are consistent with American Academy of Pediatrics recommendations.

An Integrated Analysis of Maternal-Infant Sleep, Breastfeeding, and Sudden Infant Death Syndrome Research Supporting a Balanced Discourse

Breastfeeding and the place of sleep for the mother and the infant have been controversial internationally due to reported concerns regarding infant deaths despite the known benefits of exclusive and prolonged breastfeeding, which are increased by breastfeeding at night. The aims of this integrated analysis were to (a) review breastfeeding and maternal and infant sleep research literature via historical, epidemiological, anthropological, and methodological lenses; (b) use this information to determine where we are currently in safeguarding both infant lives and breastfeeding; and (c) postulate the direction that research might take from this point forward to improve our knowledge and inform our policy and practice. Despite well-meaning but unsuccessful campaigns in some countries to dissuade parents from sleeping with their babies, many breastfeeding mothers and caregivers do sleep with their infants whether intentionally or unintentionally. Taking cultural contexts and socio-ecological circumstances into consideration, data supports policies to counsel parents and caregivers on safe sleep practices, including bed-sharing in non-hazardous circumstances, particularly in the absence of parental smoking, recent parental alcohol consumption, or sleeping next to an adult on a sofa. Further research with appropriate methodology is needed to drill down on actual rates of infant deaths, paying close attention to the definitions of deaths, the circumstances of the deaths, and confounding factors, in order to ensure we have the best information with which to derive public health policy. Introduction and use of the concept of "breastsleeping" is a plausible way to remove the negative connotations of "co-sleeping" and redirect ongoing data-driven discussions and education of best practices of breastfeeding and sleep.

The association between baby care books that promote strict care routines and infant feeding, night-time care, and maternal-infant interactions

Baby care books that promote strict infant care routines are popular, but little research has considered their impact upon maternal infant care behaviours. We explored whether mothers who have read these books guide their infant care behaviours based on their concepts and how this is associated with infant feeding, night-time care, and response to infant's needs. Three hundred and fifty-four U.K. mothers with a baby aged 0-12 months completed an online questionnaire exploring use of baby care books, motivations for use, whether guidance was followed, and infant care behaviours. Mothers who read the books were drawn to them for information about how to settle their infant, infant sleep, and infant feeding behaviour. Those who read the books were less likely to breastfeed, feed responsively, have their infant sleep in the same room, cuddle their infant to sleep, or respond promptly to infant cries. Although the causality between reading these books and care cannot be determined through this study design, and is likely bidirectional with some reading the books to confirm existing preferences, around 25-40% of mothers noted the information determined their care decisions. Regardless of specific causal pathways, there is an association between these books and behaviours that go against infant feeding and responsive care recommendations. Understanding what drives mothers to follow these books and increasing support for new mothers in these areas is important. The findings will be important for those supporting mothers in the perinatal period in starting conversations around responsive infant care.

Trends and Factors Associated with Breastfeeding and Infant Sleep Practices in Georgia

Breastfeeding benefits both infant and mother, including reducing the risk of Sudden Infant Death Syndrome (SIDS). To further reduce risk of SIDS, the American Academy of Pediatrics recommends infants sleep on their backs on a separate sleep surface. Our objective was to describe trends and factors associated with breastfeeding and infant sleep practices in Georgia. Pregnancy Risk Assessment Monitoring System 2004-2013 data were obtained from the Georgia Department of Public Health. Chi square tests for trends were utilized to determine whether there were significant linear trends in breastfeeding and infant sleep overtime and by survey phase. After exclusions, 4643 cases remained for analysis. From 2004 to 2013, there was a slight (insignificant) decrease in breastfeeding initiation, with the highest proportion in 2010 (79.9%) and the lowest in 2013 (66.9%). Rates of exclusive breastfeeding increased significantly from 2004 (31.3%) to 2013 (81.7%). During that time, the proportion of infants being placed back to sleep slightly decreased (though not significantly), from 59.7 to 48.9%. The proportion of mothers who reported never bed-sharing increased significantly from 26.7 to 45.1% over this period. The decreasing breastfeeding initiation rates in Georgia diverge from national upward trends, however, exclusive breastfeeding rates by survey phase were slightly higher than national trends. Our results suggest the need for targeted education and support for breastfeeding and safe sleep practices. State-level trends data on breastfeeding and infant sleep practices provide valuable information for state-level public health professionals and policy makers, health care providers, and breastfeeding and safe sleep advocates.

Nurses Leading Safe Infant Sleep Initiatives in the Hospital Setting

Every day, 10 otherwise healthy infants die from sleep-related deaths in the United States. These deaths, termed sudden unexpected infant death, remain the leading cause of post-neonatal death in the United States despite known modifiable risk factors and prevention recommendations. In birthing hospitals, many parents report being given incorrect and sometimes no information about infant sleep safety, which creates immediate and long-term safety concerns. In this article, we provide an overview of sudden unexpected infant death, including sudden unexpected postnatal collapse, and the latest safe sleep recommendations from the American Academy of Pediatrics. We also offer practical guidelines for nurses-those working at the bedside and those in leadership positions-who may be seeking to improve the quality of infant sleep practices in their organizations.

A Context-Aware Indoor Air Quality System for Sudden Infant Death Syndrome Prevention

Context-aware monitoring systems designed for e-Health solutions and ambient assisted living (AAL) play an important role in today's personalized health-care services. The majority of these systems are intended for the monitoring of patients' vital signs by means of bio-sensors. At present, there are very few systems that monitor environmental conditions and air quality in the homes of users. A home's environmental conditions can have a significant influence on the state of the health of its residents. Monitoring the environment is the key to preventing possible diseases caused by conditions that do not favor health. This paper presents a context-aware system that monitors air quality to prevent a specific health problem at home. The aim of this system is to reduce the incidence of the Sudden Infant Death Syndrome, which is triggered mainly by environmental factors. In the conducted case study, the system monitored the state of the neonate and the quality of air while it was asleep. The designed proposal is characterized by its low cost and non-intrusive nature. The results are promising.

How do caregivers understand and respond to unsettled infant behaviour in Vietnam? A qualitative study

BACKGROUND

Unsettled infant behaviours are a common source of concern for new parents and have been associated with perinatal common mental disorders amongst women in high-income settings. There is little evidence about how unsettled infant behaviours are understood and managed in low and lower-middle income countries. This study aimed to describe caregivers' understandings of, and responses to, unsettled infant behaviours in Vietnam and their family caregiving contexts.

METHODS

Women who were mothers of infants aged 0-6 months were purposively recruited from two sites in Thua Thien Hue Province, Vietnam (one urban and one rural). An additional group of women who were grandmothers were recruited by snowball sampling. Data were collected in semi-structured interviews about demographic information, infant feeding practices, descriptions of infant crying episodes, beliefs about why infants cry, settling strategies, infant sleeping arrangements and sources of advice on infant care. Translated interview transcripts were analysed thematically.

RESULTS

Twenty-four interviews were undertaken (21 with mothers and 3 with grandmothers). Five major themes emerged from the data after analysis: infant settling techniques, sources of information on unsettled infant behaviour, understandings of the causes of infant crying, the emotional responses of caregivers and the intergenerational household context. Infants were commonly cared for by people from multiple generations, particularly during the day. Infant settling was characterized by attending to infants immediately, breastfeeding and bed-sharing with parents during the night. Most mothers received advice on caregiving from family members. Infant crying was attributed to hunger and loneliness, as well as traditional beliefs that the infant was being upset by 'ghosts' or becoming 'hot'. Women described feeling anxious, frustrated and helpless in relation to unsettled behaviours amongst their infants.

CONCLUSIONS

Educational interventions on interpreting infant cues, infant sleep requirements and bed sharing may be appropriate in Vietnam if multiple generations are included and traditional beliefs about infant crying are addressed.

Is it Time for a Sudden Infant Death Syndrome (SIDS) Awareness Campaign? Community Stakeholders' Perceptions of SIDS

Background

Sudden infant death syndrome (SIDS) remains a leading cause of infant death in the United States and in Virginia, the SIDS rate is higher than the national average. We sought to gauge the perceptions among community-identified stakeholders as to community resource needs to reduce SIDS.

Methods

We used snowball sampling to identify important community stakeholders to be interviewed as key informants. A semi-structured interview lasting 45 min-2 hours was delivered to determine resource needs to reduce SIDS, and whether high-risk community members were aware of SIDS risk factors among stakeholders representing a variety of disciplines. Interviews were conducted in two geographic areas with higher than average rates of infant mortality, an urban district, Winchester City, VA and a rural district, Page County, VA.

Results

A total of 74 interviews were completed with stakeholders in healthcare, health departments, social services, law enforcement, education/childcare, faith-based institutions, non-profit agencies and non-affiliated community members. The majority of respondents perceive that high-risk community members are not aware of factors that can lead to SIDS (50%). Participants suggested that more "education" is needed to further reduce the rates of SIDS in their communities (73%). Respondents detailed that more pervasive, strategic, and multi-channeled education is necessary to reduce cases of SIDS.

Conclusion

Community leaders perceive that high-risk community members are not fully aware of risk factors that can lead to SIDS. Maternal/child health stakeholders in these Virginia locales suggested more community-based education as a potential solution to SIDS.

Parent-infant co-sleeping and the implications for sudden infant death syndrome

In 2015 the National Institute for Health and Care Excellence (NICE) updated its 2006 guideline to clarify the association between parent infant co-sleeping and sudden infant death syndrome (SIDS). The practice of co-sleeping is a topic of continuing controversy and debate. Rather than highlighting the risks, the emphasis of the NICE guideline is to provide parents with balanced information so that they can make informed decisions about where their babies sleep. This contradicts previous public health messages on co-sleeping that discourages parents from the practice. Consequently, the updated national guideline has been criticised for failing to provide parents with safer sleep information, which has led to widespread confusion for parents and professionals. Health professionals can deliver safer sleep advice to support parents in their decision-making. However, as a result of inconsistent guidelines and evidence about parent-infant co-sleeping, health professionals may feel apprehensive and ill-equipped to provide advice and support. This article draws on a non-exhaustive literature review to discuss the risks and benefits of parent-infant co-sleeping, and the implications of this practice for SIDS. It also aims to provide transparency and improve understanding for health professionals so that they can support parents to adopt safer sleep strategies for their baby.

Prevention Messages in Parent-Infant Bed-Sharing: Message Source, Credibility, and Effectiveness

Objective. Despite educational outreach, bed-sharing prevalence is rising. Mothers’ and fathers’ bed-sharing practices, prevention message source, perceived source credibility, and the effectiveness of the prevention message were evaluated. Methods. Data were collected from 678 community parents via an online survey. Results were analyzed using descriptive statistics and phi tests. Results. Bed-sharing reasons focused on comfort and ease. Mothers were more likely to receive prevention messages from individual professionals or organizations, whereas fathers were more likely to hear prevention messages from spouses/coparents and grandfathers. Physicians were the most common source, and physicians and grandmothers were rated as the most credible and effective. Conclusions. Prevention message source varies between mothers and fathers, highlighting the need for continued research with fathers. Grandmothers and physicians are effective and credible sources of prevention messages. Although less frequent, prevention messages from grandmothers were most effective. There was no evidence of effective messages from educational campaigns.

Parent decision factors, safety strategies, and fears about infant sleep locations

Infant sleep safety is a primary concern of parents. Infant sleep locations vary around the world.

PURPOSE

This pilot study investigated the decision factors, fears, and safety strategies reported by parents internationally.

METHODS

participants (n=49) recruited online from 10 countries completed an anonymous Internet survey in English and submitted a picture of the infant's primary nighttime sleep location. Pictures were coded into 'shared' (29%) or 'separate' (71%) sleep surfaces.

RESULTS

primary decision factors about infant sleep location were safety, comfort, family sleep quality, and overall ease. Parents maximized safety by providing a clear sleep surface, no blankets, no toys, sleep sack use, and a firm mattress. Different worries and fears emerged depending on the sleep surface.

CONCLUSION

differences in the specific worries and strategies used by parents when deciding whether to share or not share a sleep surface with an infant may be used to tailor future interventions.

Wahakura Versus Bassinet for Safe Infant Sleep: A Randomized Trial

OBJECTIVES

To compare an indigenous sleep device (wahakura) for infants at high risk for sudden unexpected death with a bassinet, for measures of infant sleep position, head covering, breastfeeding, bed-sharing, and maternal sleep and fatigue.

METHODS

A total of 200 mainly Māori pregnant women were recruited from deprived areas of New Zealand. They were randomized to receive a bassinet or wahakura and asked to sleep the infant in this device from birth. Questionnaires at 1, 3, and 6 months and an overnight infrared video in the home at 1 month were completed.

RESULTS

An intention-to-treat and an "as-used" analysis of questionnaires showed no group differences at 1, 3, and 6 months in infant-adult direct bed-sharing (7% vs 12%, P = .24 at 1 month), and at the 6-month interview, the wahakura group reported twice the level of full breastfeeding (22.5% vs 10.7%, P = .04). Maternal sleep and fatigue were not significantly different between groups. Video identified no increase in head covering, prone/side sleep position, or bed-sharing in the wahakura group, either from intention-to-treat analysis, or when analyzed for actual sleep location.

CONCLUSION

There were no significant differences in infant risk behaviors in wahakura compared with bassinets and there were other advantages, including an increase in sustained breastfeeding. This suggests wahakura are relatively safe and can be promoted as an alternative to infant-adult bed-sharing. Policies that encourage utilization are likely to be helpful in high-risk populations.

Safe sleeping positions: practice and policy for babies with cleft palate

Guidance recommends 'back to sleep' positioning for infants from birth in order to reduce the risk of sudden infant death. Exceptions have been made for babies with severe respiratory difficulties where lateral positioning may be recommended, although uncertainty exists for other conditions affecting the upper airway structures, such as cleft palate. This paper presents research of (i) current advice on sleep positioning provided to parents of infants with cleft palate in the UK; and (ii) decision making by clinical nurse specialists when advising parents of infants with cleft palate. A qualitative descriptive study used data from a national survey with clinical nurse specialists from 12 regional cleft centres in the UK to investigate current practice. Data were collected using semi-structured telephone interviews and analysed using content analysis. Over half the regional centres used lateral sleep positioning based on clinical judgement of the infants' respiratory effort and upper airway obstruction. Assessment relied upon clinical judgement augmented by a range of clinical indicators, such as measures of oxygen saturation, heart rate and respiration.

CONCLUSION

Specialist practitioners face a clinical dilemma between adhering to standard 'back to sleep' guidance and responding to clinical assessment of respiratory effort for infants with cleft palate. In the absence of clear evidence, specialist centres rely on clinical judgement regarding respiratory problems to identify what they believe is the most appropriate sleeping position for infants with cleft palate. Further research is needed to determine the best sleep position for an infant with cleft palate. What is Known • Supine sleep positioning reduces the risk of sudden infant death in new born infants. • There is uncertainty about the benefits or risks of lateral sleep positioning for infants with upper airway restrictions arising from cleft palate. What is New • Variability exists in the information/advice provided to parents of infants with cleft palate regarding sleep positioning. • Over half the national specialist centres for cleft palate in the UK advise positioning infants with CP in the lateral position as a routine measure to reduce difficulties with respiration.

Infant Safe Sleep Interventions, 1990-2015: A Review

Sleep-related infant deaths remain a major public health issue. Multiple interventions have been implemented in efforts to increase adherence to safe sleep recommendations. We conducted a systematic review of the international research literature to synthesize research on interventions to reduce the risk of sleep-related deaths and their effectiveness in changing infant sleep practices. We searched PubMed, CINAHL, PsycINFO, and Google Scholar for peer-reviewed articles published between 1990 and 2015 which described an intervention and reported results. Twenty-nine articles were included for review. Studies focused on infant caregivers, health care professionals, peers, and child care professionals. Targeted behaviors included sleep position, location, removing items from the crib, breastfeeding, smoke exposure, clothing, pacifier use, and knowledge of Sudden Infant Death Syndrome. Most articles described multi-faceted interventions, including: one-on-one or group education, printed materials, visual displays, videos, and providing resources such as cribs, pacifiers, wearable blankets, and infant t-shirts. Two described public education campaigns, one used an educative questionnaire, and one encouraged maternal note taking. Health professional interventions included implementing safe sleep policies, in-service training, printed provider materials, eliciting agreement on a Declaration of Safe Sleep Practice, and sharing adherence data. Data collection methods included self-report via surveys and observational crib audits. Over half of the studies utilized comparison groups which helped determine effectiveness. Most articles reported some degree of success in changing some of the targeted behaviors; no studies reported complete adherence to recommendations. Future studies should incorporate rigorous evaluation plans, utilize comparison groups, and collect demographic and collect follow-up data.

Contested moral landscapes: Negotiating breastfeeding stigma in breastmilk sharing, nighttime breastfeeding, and long-term breastfeeding in the U.S. and the U.K

Recent public health breastfeeding promotion efforts have galvanized media debates about breastfeeding in wealthy, Euro-American settings. A growing body of research demonstrates that while breastfeeding is increasingly viewed as important for health, mothers continue to face significant structural and cultural barriers. Concerns have been raised about the moralizing aspects of breastfeeding promotion and its detrimental effects on those who do not breastfeed. Far less, however, is known about the moral experiences of those who pursue breastfeeding. This study draws together research on breastmilk sharing (2012-2016) and nighttime breastfeeding from the U.S. (2006-2009), and long-term breastfeeding from the U.K. (2008-2009) from three ethnographic projects to address this gap. Comparative analysis of these cases reveals that while breastfeeding is considered ideal infant nutrition, aspects of its practice continue to evoke physical and moral danger, even when these practices are implemented to facilitate breastfeeding. Breastmilk sharing to maintain exclusive breastmilk feeding, nighttime breastfeeding and bedsharing to facilitate breastfeeding, and breastfeeding beyond the accepted duration are considered unnecessary, unhealthy, harmful or even deadly. The sexual connotations of breastfeeding enhance the morally threatening qualities of these practices. The cessation of these "problematic" breastfeeding practices and their replacement with formula-feeding or other foods is viewed as a way to restore the normative social and moral order. Mothers manage the stigmatization of these breastfeeding practices through secrecy and avoidance of health professionals and others who might judge them, often leading to social isolation. Our findings highlight the divide between perceptions of the ideal of breastfeeding and its actual practice and point to the contested moral status of breastfeeding in the U.S. and the U.K. Further comparative ethnographic research is needed to illuminate the lived social and moral experiences of breastfeeding, and inform initiatives to normalize and support its practice without stigmatizing parents who do not breastfeed.

Infant mortality among the Canadian-born offspring of immigrants and non-immigrants in Canada: a population-based study

BACKGROUND

Adult immigrants in Canada have a survival advantage over their Canadian-born counterparts. It is unknown whether migrants are able to transmit their survival advantage to their Canadian-born children.

METHODS

Neonatal and postneonatal mortality between the Canadian-born population and 12 immigrant subgroups were compared using 1990-2005 linked birth-infant death records. Age-at-death specific mortality rates and rate differences were calculated by nativity status and maternal birthplace. A chi-square statistic was used to compare group differences in maternal sociodemographic characteristics. Multivariate survival analysis was used to estimate the effect of maternal birthplace on neonatal and postneonatal mortality, net of maternal sociodemographic and infant characteristics.

RESULTS

Overall, immigrants had lower rates of neonatal and postneonatal mortality than the Canadian-born population. But the adjusted risk of neonatal mortality was higher for Sub-Saharan African (hazard ratio [HR] = 1.32; 95 % confidence interval [CI] = 1.05, 1.66), Haitian (HR = 2.29, 95 % CI = 1.90, 2.76), non-Spanish Caribbean (HR = 1.38; 95 % CI = 1.01, 1.89), and Pakistani (HR = 1.87; 95 % CI = 1.31, 2.68) migrants relative to Canadian-born women. There were fewer significant disparities in postneonatal death, with higher adjusted risks of mortality observed for Pakistani (HR = 2.67, 95 % CI = 1.77, 4.02) and Haitian (HR = 1.41, 95 % CI = 1.02, 1.97) migrants only.

CONCLUSION

Inequalities in infant mortality are more concentrated in the neonatal period. Contingent on surviving the first 27 days after birth, the infants of most immigrants (except those from Haiti and Pakistan) have the same chances of survival as the infants of Canadian-born women. Improvements in prenatal care and access to postpartum care may reduce disparities in infant mortality.

Parental understanding and self-blame following sudden infant death: a mixed-methods study of bereaved parents' and professionals' experiences

OBJECTIVES

Improvements in our understanding of the role of modifiable risk factors for sudden infant death syndrome (SIDS) mean that previous reassurance to parents that these deaths were unpreventable may no longer be appropriate. This study aimed to learn of bereaved parents' and healthcare professionals' experiences of understanding causes of death following detailed sudden unexpected death in infancy (SUDI) investigations. The research questions were: How do bereaved parents understand the cause of death and risk factors identified during detailed investigation following a sudden unexpected infant death? What is the association between bereaved parents' mental health and this understanding? What are healthcare professionals' experiences of sharing such information with families?

DESIGN

This was a mixed-methods study using a Framework Approach.

SETTING

Specialist paediatric services.

PARTICIPANTS

Bereaved parents were recruited following detailed multiagency SUDI investigations; 21/113 eligible families and 27 professionals participated giving theoretical saturation of data.

DATA COLLECTION

We analysed case records from all agencies, interviewed professionals and invited parents to complete the Hospital Anxiety and Depression Scale (HADS) and questionnaires or in-depth interviews.

RESULTS

Nearly all bereaved parents were able to understand the cause of death and several SIDS parents had a good understanding of the relevant modifiable risk factors even when these related directly to their actions. Paediatricians worried that discussing risk factors with parents would result in parental self-blame and some deliberately avoided these discussions. Over half the families did not mention blame or blamed no one. The cause of death of the infants of these families varied. 3/21 mothers expressed overwhelming feelings of self-blame and had clinically significant scores on HADS.

CONCLUSIONS

Bereaved parents want detailed information about their child's death. Our study suggests parents want health professionals to explain the role of risk factors in SIDS. We found no evidence that sharing this information is a direct cause of parental self-blame.

The relationship between planned and reported home infant sleep locations among mothers of late preterm and term infants

To compare maternal report of planned and practiced home sleep locations of infants born late preterm (34 0/7 to 36 6/7 gestational weeks) with those infants born term (≥37 0/7 gestational weeks) over the first postpartum month. Open-ended semi-structured maternal interviews were conducted in a US hospital following birth and by phone at 1 month postpartum during 2010-2012. Participants were 56 mother-infant dyads: 26 late preterm and 30 term. Most women planned to room share at home with their infants and reported doing so for some or all of the first postpartum month. More women reported bed sharing during the first postpartum month than had planned to do so in both the late preterm and term groups. The primary reason for unplanned bed sharing was to soothe nighttime infant fussiness. Those participants who avoided bed sharing at home commonly discussed their fear for infant safety. A few parents reported their infants were sleeping propped on pillows and co-sleeping on a recliner. Some women in both the late preterm and term groups reported lack of opportunity to obtain a bassinet prior to childbirth. The discrepancy between plans for infant sleep location at home and maternally reported practices were similar in late preterm and term groups. Close maternal proximity to their infants at night was derived from the need to assess infant well-being, caring for infants, and women's preferences. Bed sharing concerns related to infant safety and the establishment of an undesirable habit, and alternative arrangements included shared recliner sleep.

Parent-child bed-sharing: The good, the bad, and the burden of evidence

The practice of parent and child sharing a sleeping surface, or 'bed-sharing', is one of the most controversial topics in parenting research. The lay literature has popularized and polarized this debate, offering on one hand claims of dangers, and on the other, of benefits - both physical and psychological - associated with bed-sharing. To address the scientific evidence behind such claims, we systematically reviewed 659 published papers (peer-reviewed, editorial pieces, and commentaries) on the topic of parent-child bed-sharing. Our review offers a narrative walkthrough of the many subdomains of bed-sharing research, including its many correlates (e.g., socioeconomic and cultural factors) and purported risks or outcomes (e.g., sudden infant death syndrome, sleep problems). We found general design limitations and a lack of convincing evidence in the literature, which preclude making strong generalizations. A heat-map based on 98 eligible studies aids the reader to visualize world-wide prevalence in bed-sharing and highlights the need for further research in societies where bed-sharing is the norm. We urge for multiple subfields - anthropology, psychology/psychiatry, and pediatrics - to come together with the aim of understanding infant sleep and how nightly proximity to the parents influences children's social, emotional, and physical development.

Reasons for mother-infant bed-sharing: a systematic narrative synthesis of the literature and implications for future research

Mother-infant bed-sharing has been a common practice for centuries. Understanding the reasons parents choose to bed-share can help tailor safe sleep education. The purpose of this article was to systematically review the international literature on: (1) reasons parents bed-share, (2) the cultural context of bed-sharing, and (3) implications for interventions and future research. The search occurred August-September 2013 via PubMed, CINAHL, and Psyc INFO using the terms: "infant," "sleep," "bed shar*," "co sleep*," "sleep location," "sleep practices," and "sleep arrangements," alone or in combination. Google Scholar was searched using: "bed share," "bed sharing," "co sleep," and "co sleeping." Inclusion criteria were: (1) referenced bed-sharing with infants 12 months or younger; (2) provided reasons for bed-sharing; and (3) published between 1990 and 2013. Studies were excluded if they focused on disorders such as epilepsy, breathing disorders, or among multi-gestational infants. Narrative synthesis was used to summarize findings. Thirty-four studies met inclusion criteria. The main themes around bed-sharing based on this synthesis included: (1) breastfeeding, (2) comforting, (3) better/more sleep, (4) monitoring, (5) bonding/attachment, (6) environmental, (7) crying, (8) tradition, (9) disagree with danger, and (10) maternal instinct. Findings suggest that future research should examine parents' decision-making process on infant sleep location, including how they weigh personal reasons and sources of advice. Public health interventions should incorporate the particular reasons of the population they are targeting. Clinicians should discuss infant sleep environment with each family, along with their motivations for choosing this environment, and work within that framework to address the safety of the sleep environment.

A qualitative study in parental perceptions and understanding of SIDS-reduction guidance in a UK bi-cultural urban community

Background

Differences in both Sudden Infant Death Syndrome (SIDS) rates and infant care practices between white British and South Asians in UK are well known, but research has not yet examined how these two groups understand and implement SIDS-reduction guidance. This study aimed to discover how white British and Pakistani mothers in Bradford recall, understand and interpret SIDS-reduction guidance, and to explore whether and how they implement this guidance in caring for their infants.

Methods

In-depth narrative interviews with 46 mothers (25 white British origin and 21 Pakistani origin) of 8–12 week old infants recruited from the pool of participants enrolled in the ‘Born in Bradford’ (BiB) cohort study.

Results

All mothers were aware of UK SIDS-reduction guidance from leaflets presented to them during antenatal or postnatal interactions with health care providers. Pakistani mothers tended to dismiss the guidance in toto as being irrelevant to their cultural practices; white British mothers dismissed, adapted and adopted aspects of the guidance to suit their preferred parenting decisions and personal circumstances. Many mothers misunderstood or misinterpreted the guidance given and explained their infant care behaviour according to their social and cultural circumstances.

Conclusions

Current SIDS reduction information in the UK does not meet the needs of immigrant families, and is easily misinterpreted or misunderstood by mothers from all sections of the community. Tailored information acknowledging cultural differences in infant care practices is vital, as is greater discussion with all mothers about the reasons for SIDS reduction guidance.

Housing influences among sleep-related infant injury deaths in the USA

This article examines the role of housing conditions in sleep-related infant injury death, a leading cause of infant mortality in the USA. The use of an unsafe sleep surface is a major risk factor for sleep-related infant injury. This exploratory study examined contextual circumstances, specifically those related to the physical environment, which may contribute to caregivers' decisions to place an infant on an unsafe sleep surface. It employed a retrospective review of 255 sleep-related infant injury death cases in a large urban area from 2004 to 2010 where an infant was found sleeping on an unsafe sleep surface, including 122 cases where a crib or bassinet was identified in the home. Quantitative findings indicated no differences in demographic or risk characteristics between infants with cribs or bassinets and those without them. Qualitative findings suggested the lack of crib or bassinet use may be related to environmental factors influenced by poverty, specifically crowded living space, room temperature and vermin infestation. This study suggests that infants may be at risk of sleep-related injury deaths even when a crib or bassinet is present in the home and supports the consideration of housing conditions in health promotion efforts to reduce infant mortality. Understanding environmental factors that may contribute to infants sleeping on an unsafe surface can help maternal child health and public health professionals develop more appropriate interventions that address deleterious living conditions.

Maternal nativity and sleep-related infant injury deaths in New York City

BACKGROUND

Half of all births in New York City are to women born outside of the United States whose infant care practices may differ from official recommendations from the American Academy of Pediatrics. These infants have an overall lower infant mortality rate than those of their US-born counterparts.

AIMS

The aims of this study were to examine sleep-related infant injury death, a leading cause of infant mortality, and its risk factors among infants of US-born and foreign-born women in a large, diverse urban area.

STUDY DESIGN

Data for 344 infant death cases from medical examiner and vital statistics records were analyzed. Rate ratios and 95% CIs, calculated with Poisson regression models, were used to quantify differences in death rates by maternal and infant characteristics. Bivariate and logistic regression analyses were used to examine differences within the sample of sleep-related infant injury deaths.

OUTCOME MEASURES

The outcome measures were rate of sleep-related injury death, and behavioral risk factors associated with these deaths: unsafe sleep positioning, bed-sharing, and excess bedding.

RESULTS

US-born mothers had a sleep-related infant injury death rate that was over three times that of foreign-born mothers, even when controlling for maternal race/ethnicity, education, and age. However, adverse sleep-related practices were not consistently more prevalent among US-born infants in the sample of deaths, even when controlling for those same demographic factors.

CONCLUSIONS

The higher rate of sleep-related infant injury death among infants of US-born mothers may be explained by more complex socio-demographic factors, or factors outside of infant sleep practices.

Methodology and recruitment for a randomised controlled trial to evaluate the safety of wahakura for infant bedsharing

BACKGROUND

Sudden Unexpected Death in Infancy (SUDI) has persistent high rates in deprived indigenous communities and much of this mortality is attributable to unsafe sleep environments. Whilst health promotion worldwide has concentrated on avoidance of bedsharing, the indigenous Māori community in New Zealand has reproduced a traditional flax bassinet (wahakura) designed to be used in ways that include bedsharing. To date there has been no assessment of the safety of this traditional sleeping device.

METHODS/DESIGN

This two arm randomised controlled trial is being conducted with 200 mother-baby dyads recruited from Māori communities in areas of high deprivation in the Hawkes Bay, New Zealand. They are randomised to wahakura or bassinet use and investigation includes questionnaires at baseline (pregnancy), when baby is 1, 3, and 6 months, and an overnight video sleep study at 1 month with monitoring of baby temperature and oxygen saturation, and measurement of baby urinary cotinine and maternal salivary oxytocin. Outcome measures are amount of time head covered, amount of time in thermal comfort zone, number of hypoxic events, amount of time in the assigned sleep device, amount of time breastfeeding, number of parental (non-feed related) touching infant events, amount of time in the prone sleep position, the number of behavioural arousals and the amount of time infant is awake overnight. Survey data will compare breastfeeding patterns at 1, 3, and 6 months as well as data on maternal mind-mindedness, maternal wellbeing, attachment to baby, and maternal sleep patterns.

DISCUSSION

Indigenous communities require creative SUDI interventions that fit within their prevailing world view. This trial, and its assessment of the safety of a wahakura relative to a standard bassinet, is an important contribution to the range of SUDI prevention research being undertaken worldwide.

Bed-sharing in the absence of hazardous circumstances: is there a risk of sudden infant death syndrome? An analysis from two case-control studies conducted in the UK

Objective

The risk of sudden infant death syndrome (SIDS) among infants who co-sleep in the absence of hazardous circumstances is unclear and needs to be quantified.

Design

Combined individual-analysis of two population-based case-control studies of SIDS infants and controls comparable for age and time of last sleep.

Setting

Parents of 400 SIDS infants and 1386 controls provided information from five English health regions between 1993–6 (population: 17.7 million) and one of these regions between 2003–6 (population:4.9 million).

Results

Over a third of SIDS infants (36%) were found co-sleeping with an adult at the time of death compared to 15% of control infants after the reference sleep (multivariate OR = 3.9 [95% CI: 2.7–5.6]). The multivariable risk associated with co-sleeping on a sofa (OR = 18.3 [95% CI: 7.1–47.4]) or next to a parent who drank more than two units of alcohol (OR = 18.3 [95% CI: 7.7–43.5]) was very high and significant for infants of all ages. The risk associated with co-sleeping next to someone who smoked was significant for infants under 3 months old (OR = 8.9 [95% CI: 5.3–15.1]) but not for older infants (OR = 1.4 [95% CI: 0.7–2.8]). The multivariable risk associated with bed-sharing in the absence of these hazards was not significant overall (OR = 1.1 [95% CI: 0.6–2.0]), for infants less than 3 months old (OR = 1.6 [95% CI: 0.96–2.7]), and was in the direction of protection for older infants (OR = 0.1 [95% CI: 0.01–0.5]). Dummy use was associated with a lower risk of SIDS only among co-sleepers and prone sleeping was a higher risk only among infants sleeping alone.

Conclusion

These findings support a public health strategy that underlines specific hazardous co-sleeping environments parents should avoid. Sofa-sharing is not a safe alternative to bed-sharing and bed-sharing should be avoided if parents consume alcohol, smoke or take drugs or if the infant is pre-term.

Application of a Socio-Ecological Model to Mother–Infant Bed-Sharing

Mother–infant bed-sharing has been associated with an increased risk of sleep-related infant deaths, and thus, health messaging has aimed to discourage this behavior. Despite this messaging, bed-sharing remains a common practice in the United States, especially among minority families. Moreover, rates of accidental suffocation and strangulation in bed (often related to bed-sharing) are on the rise, with Black infants at two to three times greater risk than Whites. Multiple studies have identified risk factors for bed-sharing, but a gap remains between findings and translation into interventions. The socio-ecological model (SEM) has been suggested as a way to study and design interventions addressing complex public health issues. This article reconceptualizes the literature on mother–infant bed-sharing using the SEM. PubMed, POPLINE, ERIC, and Psych Info were searched for articles that (a) included bed-sharing as the outcome variable, (b) were published between 2000 and 2013, (c) were conducted in the United States, and (d) included quantitative comparison of more than one factor. The following data were extracted: sample characteristics, bed-sharing definition, methods, factors examined, key findings, and conclusions. Data were summarized into five SEM levels—infant, maternal, family and household, and community and society, nested within the historical context of race. Sixteen studies met inclusion criteria. Significant factors associated with bed-sharing were present within each SEM level of influence. Educational interventions may increase efficacy by attending to multiple levels of the SEM, especially when implementing such interventions within minority subpopulations. Using a harm reduction approach to reducing the risk around bed-sharing may be one way to account for the multiple influences on bed-sharing. The science and practice of minimizing mother–infant bed-sharing may be advanced through use of the SEM.

The Baby Care Questionnaire: a measure of parenting principles and practices during infancy

•

The Baby Care Questionnaire (BCQ) measures parents’ support of parenting principles.

•

The BCQ measures two factors (principles) – structure and attunement.

•

The BCQ showed reliability – internal consistency and test–retest reliability.

•

Structure and attunement were related to parenting practices, such as breastfeeding.

•

Structure and attunement were related to perceived control over caregiving failures.

The current report provides a new framework to explore the role of parenting practices and principles during infancy. We identify structure and attunement as key parenting principles during infancy. Structure represents reliance on regularity and routines in daily life. Attunement represents reliance on infant cues and close physical contact. We suggest parents’ relative endorsement of these parenting principles is related to their choices about practices such as feeding, holding and night-time sleeping. We designed the Baby Care Questionnaire to measure parents’ endorsement of structure and attunement, as well as their daily parenting practices. We report data demonstrating the factor structure, reliability and validity of the BCQ. The BCQ, to our knowledge, is the first comprehensive measure of parenting practices and principles during infancy. We conclude with a discussion of future directions for the measure.
