Sudden infant death syndrome in child care settings

Sudden Infant Death Syndrome: Risk Factors and Newer Risk Reduction Strategies

Sudden infant death syndrome (SIDS) continues to be one of the top causes of infant death in the U.S. Despite significant public health initiatives focused on high-risk populations to enhance sleep environments and techniques. The SIDS rate has remained stable in recent years. Risk factors and newer risk reduction strategies for SIDS are the focus of this review article. We conducted a comprehensive literature search on Medline, Cochrane, Embase, and Google Scholar until July 2022. The following search strings and Medical Subject Heading (MeSH) terms were used: "SIDS," "Sudden Infant Death" and "SUID". We explored the literature on SIDS for its epidemiology, pathophysiology, the role of various etiologies and their influence, associated complications leading to SIDS, and preventive and treatment modalities. Despite a more than 50% drop-in rates since the start of the "Back to Sleep" campaign in 1994, sudden infant death syndrome (SIDS) continues to be the top cause of post-neonatal mortality in the United States, despite continued educational initiatives that support safe sleep and other risk reduction strategies. The new American Academy of Pediatrics guidelines for lowering the risk of SIDS include a lot of emphasis on sleeping habits, bedding, and environment but also include elements that are frequently ignored (i.e., prenatal care, smoking, alcohol and drug use, and childhood vaccinations). This study highlights these less-frequently discussed aspects and identifies treatments that have produced beneficial behavioral shifts that benefit newborns as well as their mothers' health and wellbeing.

Transition to a Safe Home Sleep Environment for the NICU Patient

Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (<2500 g [5.5 lb]) and 10% were born preterm (gestational age of <37 completed weeks). Many of these infants and others with congenital anomalies, perinatally acquired infections, and other disease require admission to a NICU. In the past decade, admission rates to NICUs have been increasing; it is estimated that between 10% and 15% of infants will spend time in a NICU, representing approximately 500 000 neonates annually. Approximately 3600 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome International Classification of Diseases, 10th Revision (R95), ill-defined deaths (R99), and accidental suffocation and strangulation in bed (W75). Preterm and low birth weight infants are particularly vulnerable, with an incidence of death 2 to 3 times greater than healthy term infants. Thus, it is important for health care professionals to prepare families to maintain their infant in a safe sleep environment, as per the recommendations of the American Academy of Pediatrics. However, infants in the NICU setting commonly require care that is inconsistent with infant sleep safety recommendations. The conflicting needs of the NICU infant with the necessity to provide a safe sleep environment before hospital discharge can create confusion for providers and distress for families. This technical report is intended to assist in the establishment of appropriate NICU protocols to achieve a consistent approach to transitioning NICU infants to a safe sleep environment as soon as medically possible, well before hospital discharge.

A comparison of safe sleep violations in child care and family child care learning homes in Georgia

BACKGROUND

High rates of infant death associated with sleeping practices continue to persist in the United States. Infants spend a large portion of their day with child care and family child care learning home providers. Safe sleeping practices continue to be an area of need for care providers of young children.

METHOD

The current study examines data drawn from a publicly available database of child care licensing reports in Georgia (n = 3,501), which contained data on child care centres and family child care learning homes. Information in the database included characteristics of the centres, year of data collection and the specific violations by child care provider type.

RESULTS

Results indicated clear differences in the prevalence of violations between child care centres and family child care learning homes. Within the overall sample, 13.3% of centres and family child care learning homes were cited for safe sleeping practice violations with higher prevalence in licensed child care centres and unaccredited centres. Violations were consistent with those commonly found in child care environments and inconsistent with the American Academy of Pediatrics safe sleep recommendations.

CONCLUSIONS

Data from the current study suggest a continued need for professional learning on safe sleep practices.

Paid family leave and children health outcomes in OECD countries

During the past four decades, most OECD (Organisation for Economic Co-operation and Development) countries have adopted or expanded paid family leave, which offers leave to workers following the birth or adoption of a child as well as care for ill family members. While the effects of paid maternity leave on child health have been the subject of a large body of research, little is known about fathers' leave-taking and the effects of paid paternity leave. This is a limitation, since most of the recent expansion in paid family leave in OECD countries has been to expand leave benefits to fathers. Mothers' and fathers' leave-taking may improve child health by decreasing postpartum depression among mothers, improving maternal mental health, increasing the time spent with a child, and increasing the likelihood of child medical checkup. The purpose of this paper is to examine the effects of paid family leave on the wellbeing of children, extending what we know about the effects of maternity leave and establishing new evidence on paternity leave. The paper examines the effects of paid family leave expansions on country-level neonatal mortality rates, infant mortality rates, under-five mortality rates, and the measles immunization rates in 35 OECD countries, during the time period of 1990 to 2016. Using an event study design, an approximately 1.9-5.2 percent decrease in the infant, neonatal, and under-five mortality rates has been found following the adoption of paid maternity leave. However, the beneficial impact is not as visible for extension of paid leave to fathers. The implications and potential reasons behind the larger protective effects of maternity leave over paternity leave on child health outcomes are discussed.

Observed compliance with safe sleeping guidelines in licensed childcare services

OBJECTIVE

To independently assess compliance with safe sleeping guidelines for infants <12 months in licensed childcare services.

DESIGN

Full-day, in-situ observations of childcare practices (including sleep and non-sleep periods) conducted in 2016-2017.

SETTING

Australian home-based and centre-based licensed childcare services. All subject to national regulation and legislation to comply with safe sleeping guidelines.

PARTICIPANTS

The sample was 18 licensed childcare settings (15 centre-based, 3 home-based) that had infants <12 months (n=49) attending at the time of observation. 31 educators completed self-report surveys.

MAIN OUTCOMES AND MEASURES

Standard observations of childcare practices, including a 20-item infant Safe Sleeping Guideline checklist. Educator characteristics, including each individual's knowledge, beliefs and attitudes regarding safe sleeping practices.

RESULTS

83% of childcare services were observed to be non-compliant on at least 1 of 20 target guidelines (median 2.5, max=7); 44% were observed placing infants prone/side and 67% used loose bedding, quilts, doonas/duvets, pillows, sheepskins or soft toys in cots. 71% of the childcare settings had a copy of current safe sleeping guidelines displayed either in or at entry to the infant sleep room.

CONCLUSION

Despite 25 years of public health messaging, non-compliance with safe sleeping guidelines was observed to be high in childcare services. Understanding of the reasons underlying non-compliance, particularly in contexts were legislative mandate and access to information regarding safe sleeping is high, is critical to informing ongoing public health messaging and should be the focus of future studies.

Integrative literature review: sleep patterns in infants attending nurseries

OBJECTIVE

To identify evidence available in the literature about sleep patterns of infants attending nurseries.

METHOD

An integrative review of studies published in Portuguese, English or Spanish available in full text on LILACS, CINAHL, and PubMed databases. The following descriptors sono, lactente and creches or berçários (in Portuguese) and sleep, infant and childcare or nurseries were used for LILACS, CINAHL and Pubmed, respectively. Nine studies were selected and analyzed.

RESULTS

The main component explored in the studies about sleep pattern is the sleep position of the infants, due to its association with sudden infant death syndrome. The results pointed to the need to promote and develop written guidelines regarding behavioral practices to reduce the risk of this phenomenon.

CONCLUSION

Evidence has identified sleep issues, mainly regarding the sleep position of the infant and the environment where the infant sleeps, showing that it is critical to set routines and interventions to improve the quality of sleep care of infants attending nurseries.

Characteristics of Infant Deaths during Sleep While Under Nonparental Supervision

OBJECTIVE

To compare risk factors for infant sleep-related deaths under the supervision of parents and nonparents.

STUDY DESIGN

We conducted a secondary analysis of sleep-related infant deaths from 2004 to 2014 in the National Center for Fatality Review and Prevention Child Death Review Case Reporting System. The main exposure was supervisor at time of death. Primary outcomes included sleep position, location, and objects in the environment. Risk factors for parental vs nonparental supervisor were compared using χ² and multivariable logistic regression models. Risk factors associated with different nonparental supervisors were analyzed using χ².

RESULTS

Of the 10 490 deaths, 1375 (13.1%) occurred under nonparental supervision. Infants who died under nonparental supervision had higher adjusted odds of dying outside the home (OR 12.87, 95% CI 11.31-14.65), being placed prone (OR 1.61, 95% CI 1.39-1.86) or on their side (OR 1.35, 95% CI 1.12-1.62), or being found prone (OR 1.74, 95% CI 1.50-2.02). Among infants who died under nonparental supervision, those supervised by relatives or friends were more often placed on an adult bed or couch for sleep and bed sharing (P < .0001), and to have objects in the sleep environment (P = .01).

CONCLUSIONS

Infants who died of sleep-related causes under nonparental supervision were more likely to have been placed nonsupine. Among nonparental supervisors, relatives and friends were more likely to use unsafe sleep environments, such as locations other than a crib or bassinet and bed sharing. Pediatricians should educate parents that all caregivers must always follow safe sleep practices.

Factors Associated With Choice of Infant Sleep Position

BACKGROUND AND OBJECTIVES

The American Academy of Pediatrics recommends infants be placed supine for sleep. Our objectives in this study were to, in a nationally representative sample, examine (1) prevalence of maternal intention regarding infant sleeping position and of actual practice and (2) factors associated with their choices.

METHODS

We recruited mothers from 32 US hospitals, oversampling African American and Hispanic mothers, in a nationally representative sample of mothers of infants aged 2 to 6 months. Survey questions assessed choice of usual infant sleeping position, all sleeping positions, intention for sleep position, as well as actual practice. Multivariable logistic regression analyses controlled for demographic, receipt of doctor advice, and theory of planned behavior variables (attitudes, subjective norms, and perceived control).

RESULTS

Of the 3297 mothers, 77.3% reported they usually placed their infants in the supine position for sleep, but fewer than half reported that they exclusively did so. Only 43.7% of mothers reported that they both intended to and then actually placed their infants exclusively supine. African American mothers and those who did not complete high school were more likely to intend to use the prone position. Theory of planned behavior factors (attitudes, subjective norms, and perceived control) and doctor advice were associated with maternal choice.

CONCLUSIONS

Not all mothers place their infants exclusively supine for sleep. Many mothers intend to place their infants supine yet often do not do so in actual practice. Factors potentially amenable to intervention including attitudes, subjective norms, and doctor advice are associated with intention and practice.

Risk Factors for Sleep-Related Infant Deaths in In-Home and Out-of-Home Settings

BACKGROUND AND OBJECTIVE

Multiple environmental risk factors are associated with sleep-related infant deaths. Little is known about differences in risk factors for deaths occurring in-home and out-of-home. We sought to compare risk factors for in-home and out-of-home infant deaths.

METHODS

We conducted a cross-sectional analysis of sleep-related infant deaths from 2004 to 2014 in the National Child Fatality Review and Prevention database. The main exposure was setting (in-home versus out-of-home) at time of death. Primary outcomes were known risk factors: sleep position, sleep location (eg, crib), objects in the environment, and bed sharing. Risk factors for in-home versus out-of-home deaths were compared using the χ² test and multivariate logistic regressions.

RESULTS

A total of 11 717 deaths were analyzed. Infants who died out-of-home were more likely to be in a stroller/car seat (adjusted odds ratio, 2.6; 95% confidence interval, 2.1–3.4; P < .001) and other locations (adjusted odds ratio, 1.9; 95% confidence interval, 1.5–2.3; P < .001), and placed prone (adjusted odds ratio, 1.18; 95% confidence interval, 1.05–1.32; P < .01. There were no differences in sleeping on a couch/chair or objects in the sleep environment.

CONCLUSIONS

Sleep-related infant deaths in the out-of-home setting have higher odds of having certain risk factors, such as prone placement for sleep and location in a stroller/car seat, rather than in a crib/bassinet. Caregivers should be educated on the importance of placing infants to sleep supine in cribs/bassinets to protect against sleep-related deaths, both in and out of the home.

Safe Infant Sleep Interventions: What is the Evidence for Successful Behavior Change?

Sudden infant death syndrome (SIDS) and other sleep-related infant deaths, such as accidental suffocation and strangulation in bed and ill-defined deaths, account for >4000 deaths annually in the USA. Evidence-based recommendations for reducing the risk of sleep-related deaths have been published, but some caregivers resist adoption of these recommendations. Multiple interventions to change infant sleep-related practices of parents and professionals have been implemented. In this review, we will discuss illustrative examples of safe infant sleep interventions and evidence of their effectiveness. Facilitators of and barriers to change, as well as the limitations of the data currently available for these interventions, will be considered.

Exploring the risk factors for sudden infant deaths and their role in inflammatory responses to infection

The risk factors for sudden infant death syndrome (SIDS) parallel those associated with susceptibility to or severity of infectious diseases. There is no evidence that a single infectious agent is associated with SIDS; the common thread appears to be induction of inflammatory responses to infections. In this review, interactions between genetic and environmental risk factors for SIDS are assessed in relation to the hypothesis that many infant deaths result from dysregulation of inflammatory responses to "minor" infections. Risk factors are assessed in relation to three important stages of infection: (1) bacterial colonization (frequency or density); (2) induction of temperature-dependent toxins; (3) induction or control of inflammatory responses. In this article, we review the interactions among risk factors for SIDS for their effects on induction or control of inflammatory responses. The risk factors studied are genetic factors (sex, cytokine gene polymorphisms among ethnic groups at high or low risk of SIDS); developmental stage (changes in cortisol and testosterone levels associated with 2- to 4-month age range); environmental factors (virus infection, exposure to cigarette smoke). These interactions help to explain differences in the incidences of SIDS observed between ethnic groups prior to public health campaigns to reduce these infant deaths.

Sofas and infant mortality

OBJECTIVE

Sleeping on sofas increases the risk of sudden infant death syndrome and other sleep-related deaths. We sought to describe factors associated with infant deaths on sofas.

METHODS

We analyzed data for infant deaths on sofas from 24 states in 2004 to 2012 in the National Center for the Review and Prevention of Child Deaths Case Reporting System database. Demographic and environmental data for deaths on sofas were compared with data for sleep-related infant deaths in other locations, using bivariate and multivariable, multinomial logistic regression analyses.

RESULTS

A total of 1024 deaths on sofas made up 12.9% of sleep-related infant deaths. They were more likely than deaths in other locations to be classified as accidental suffocation or strangulation (adjusted odds ratio [aOR] 1.9; 95% confidence interval [CI], 1.6-2.3) or ill-defined cause of death (aOR 1.2; 95% CI, 1.0-1.5). Infants who died on sofas were less likely to be Hispanic (aOR 0.7; 95% CI, 0.6-0.9) compared with non-Hispanic white infants or to have objects in the environment (aOR 0.6; 95% CI, 0.5-0.7) and more likely to be sharing the surface with another person (aOR 2.4; 95% CI, 1.9-3.0), to be found on the side (aOR 1.9; 95% CI, 1.4-2.4), to be found in a new sleep location (aOR 6.5; 95% CI, 5.2-8.2), and to have had prenatal smoke exposure (aOR 1.4; 95% CI, 1.2-1.6). Data on recent parental alcohol and drug consumption were not available.

CONCLUSIONS

The sofa is an extremely hazardous sleep surface for infants. Deaths on sofas are associated with surface sharing, being found on the side, changing sleep location, and experiencing prenatal tobacco exposure, which are all risk factors for sudden infant death syndrome and sleep-related deaths.

Sleeping position and health status of children at six-, eighteen- and thirty-six-month development

Using structural equation modeling to investigate the multiple pathways of sleeping position and children's early development at six-, eighteen- and thirty-six-month children, with parental demographics and child health status controlled. The participants consisted of 1783 six-month children, who were assessed using the Taiwan Birth Cohort Study Instrument. After follow-up, 1620 eighteen-month and 1630 thirty-six-month children participated in the second and third assessments, respectively. With potential confounding factors controlled, children at six-month of mothers with a lower level of education tended to sleep supine (β=-0.08, p=0.001). Compared to those sleeping in the prone and side positions, infants in the supine had slower gross and fine motor development (β=-0.11, p<.001; β=-0.12, p=0.030); however, the effect of sleeping position on the children's development dissipated at eighteen- and thirty-six-month. Sleeping position had effect on children's development at six-month; however, this effect was transient. Instead, chronic illness and maternal level of education had a more persistent effect on children's development.

The physician's role in reducing SIDS

Despite a sustained public education campaign aimed at reducing the risks of sudden infant death syndrome (SIDS), it remains one of the leading causes of infant death. This study aims to determine physicians' knowledge of SIDS and whether physicians are discussing how to reduce the risk of SIDS with parents. A cross-sectional survey is sent to 912 pediatricians, family practitioners, and obstetrician-gynecologists in Central New York State. The response rate is 23.5%. Almost all respondents (99.5%) agree that certain measures can be taken to reduce the risks of SIDS, but 30.3% incorrectly state that the safest sleep position is something other than on the back. Although 97.6% agree that it is important to discuss SIDS with parents, 30% admit to not discussing this information. To continue to decrease the SIDS rate, physicians must take responsibility for educating themselves and parents about safe sleep practices and other SIDS risk factors.

Sudden infant death syndrome: changing epidemiologic patterns in California 1989-2004

OBJECTIVE

To evaluate the changes of sudden infant death syndrome (SIDS) epidemiology in California.

STUDY DESIGN

We used 1989 to 2004 California statewide death registry data. SIDS cases were selected by "age of decedent" <1 year and "cause of death" listed as SIDS.

RESULTS

We identified 6303 cases (61% males) of SIDS. SIDS incidence rate decreased by 77%, from 1.38 per 1000 births in 1989 to 0.31 per 1000 births in 2004. No further decrease in SIDS incidence was noted from 2002 to 2004. The incidence rate was highest among blacks (2.02 per 1000 births) and lowest in Asian/Pacific Islanders (0.46 per 1000 births). The overall median age at death was 82 days, with no significant change over time. However, the peak age at death shifted from 2 months of age in 1989 to 2001 to 3 months of age in 2002 to 2004. Seasonal variation in the incidence of SIDS was attenuated. The difference in incidence rates between weekdays and weekends increased over the study period.

CONCLUSIONS

The incidence rate of SIDS declined in California from 1989 to 2001, with no further decline after 2002. Several epidemiologic changes were noted: The peak age of SIDS death shifted from 2 months to 3 months of age; seasonal variation diminished; and weekday to weekend difference became more pronounced.

Reducing the risk of sudden infant death syndrome in child care and changing provider practices: lessons learned from a demonstration project

OBJECTIVE

The goal was to evaluate, through an American Academy of Pediatrics demonstration project, the effectiveness of a curriculum and train-the-trainer model in changing child care providers' behaviors regarding safe infant sleep practices.

METHODS

Participating licensed child care centers and family child care homes were assigned randomly to intervention and control groups. Observers performed an initial unannounced visit to each site, to watch infants being placed for sleep, to inventory sleep policies, and to administer questionnaires to center staff members. Trainers then used the American Academy of Pediatrics curriculum in educational sessions at intervention sites. Three months later, observers conducted a follow-up observation at each site, and staff members completed a questionnaire about logistic barriers encountered in implementation of safe sleep recommendations.

RESULTS

A total of 264 programs and 1212 providers completed the study; the care of 1993 infants was observed. Provider awareness of the American Academy of Pediatrics infant supine sleep position recommendation increased from 59.7% (both groups) to 64.8% (control) and 80.5% (intervention). Exclusive use of the supine position in programs increased from 65.0% to 70.4% (control) and 87.8% (intervention). Observed supine placement increased from 51.0% to 57.1% (control) and 62.1% (intervention).

CONCLUSIONS

A sudden infant death syndrome risk reduction curriculum using a train-the-trainer model is effective in improving the knowledge and practices of child care providers. Perceived parental objections, provider skepticism about the benefits of supine positioning, and lack of program policies and training opportunities are important barriers to implementation of safe sleep policies. Continued education of parents, expanded training efforts, and statewide regulations, mandates, and monitoring are critical to ongoing efforts to decrease further the risk of sudden infant death syndrome in child care.

Sudden infant death syndrome (SIDS) and child care centres (CCC)

Our aim was to review the risk of sudden infant death syndrome (SIDS) when infants are in child care (CC), to discuss factors potentially responsible for SIDS in this setting and to describe the impact of previous information campaigns on SIDS in CC. There is a remarkably increased risk of SIDS in CC settings. Special education focussing on a safe sleeping environment has resulted in a decrease of practices known to be associated with SIDS. However, despite a safe sleep environment SIDS prevalence remains disproportionately high.

CONCLUSION

Efforts must continue to ensure safe sleeping practices in CC facilities. The possibility of other explanations for the increased prevalence of SIDS in CC settings, such as changes in infant care or stress, must be considered as well.

Sudden infant death syndrome

Despite declines in prevalence during the past two decades, sudden infant death syndrome (SIDS) continues to be the leading cause of death for infants aged between 1 month and 1 year in developed countries. Behavioural risk factors identified in epidemiological studies include prone and side positions for infant sleep, smoke exposure, soft bedding and sleep surfaces, and overheating. Evidence also suggests that pacifier use at sleep time and room sharing without bed sharing are associated with decreased risk of SIDS. Although the cause of SIDS is unknown, immature cardiorespiratory autonomic control and failure of arousal responsiveness from sleep are important factors. Gene polymorphisms relating to serotonin transport and autonomic nervous system development might make affected infants more vulnerable to SIDS. Campaigns for risk reduction have helped to reduce SIDS incidence by 50-90%. However, to reduce the incidence even further, greater strides must be made in reducing prenatal smoke exposure and implementing other recommended infant care practices. Continued research is needed to identify the pathophysiological basis of SIDS.

Meaning-making in the aftermath of sudden infant death syndrome

The reconstruction of meaning in the aftermath of sudden infant death syndrome (SIDS) is part of the grieving process but has to date been poorly understood. Earlier theorists including Freud, Bowlby and Kübler-Ross provided a foundation for what occurs during this time using stage theories. More recent researchers, often using qualitative techniques, have provided a more complex and expanded view that enhances our knowledge of meaning reconstruction following infant loss. This overview of representative contemporary authors compares and contrasts them with the longstanding models that are being supplanted within the emerging field of thanatology. Understanding parental reactions within this new framework can help healthcare professionals in dealing with those affected by SIDS and provide a more empathic and sensitive approach to individual differences. Parents' own accounts of their post-SIDS experience are consistent with these newer theories. Comprehending how parents cope and reconstruct their lives is an important element in providing appropriate psychological support services.

State child care regulations regarding infant sleep environment since the Healthy Child Care America-Back to Sleep campaign

BACKGROUND

Despite overall decreases in sudden infant death syndrome deaths and prone sleeping, the proportion of sudden infant death syndrome deaths that occurs in child care settings has remained constant at approximately 20%. In 2003, the American Academy of Pediatrics' Healthy Child Care America program launched its own Back to Sleep campaign to promote the Back to Sleep message for those who care for young children.

OBJECTIVES

The purpose of this study was to evaluate the effectiveness of the first 2 years of the Healthy Child Care America-Back to Sleep campaign in improving child care regulations by assessing the inclusion of the elements of a safe sleep environment in the individual state regulations for child care centers and family child care homes.

METHODS

We examined regulations available in October 2005 for licensed child care centers and family child care homes in the 50 states and the District of Columbia for specific regulations pertaining to (1) sudden infant death syndrome risk-reduction training for child care providers, (2) infant sleep position, (3) crib safety, (4) bedding safety, (5) smoking, and (6) provision of information about sleep positioning policies and arrangements to parents before the infant is enrolled in child care.

RESULTS

Since 2003, when the Healthy Child Care America-Back to Sleep campaign began, 60 of the 101 state regulations for either child care centers or FCCHs have been revised. More than half of these regulations written since 2003 mandate a nonprone sleep position and restrictions on soft bedding in the crib, and the change in these regulations since 2003 is statistically significant. However, of the 101 existing state regulations, only 49 require that infants sleep nonprone, 18 mandate sudden infant death syndrome training for child care providers, 81 have > or = 1 crib safety standard, and 43 restrict soft bedding in the crib. Only 4 regulations require that parents be provided with sleep policy information.

CONCLUSIONS

The initial 2 years of the Healthy Child Care America Back to Sleep campaign have been successful in promoting safe infant sleep regulations. Efforts must continue so that safe sleep regulations exist in all jurisdictions.

Sudden infant death syndrome: The colon connection

The etiology of sudden infant death syndrome (SIDS) is not known. Various maternal and infant risk factors have been identified. Adoption of the non-prone position has reduced the incidence of SIDS but has not eliminated the problem. Some sulfate reducing bacteria in the colon produce hydrogen sulfide (H2S) which is as toxic as hydrogen cyanide. Normally, the colonic mechanism for metabolizing and detoxifying H2S is very effective and no H2S appears in the exhaled breath although small amounts are present in the flatus. We are putting forth the hypothesis that in some cases of SIDS colonocytic mechanism for detoxifying H2S may not have matured by the age of 3 months and H2S may be absorbed resulting in SIDS. The hypothesis can be tested by in vitro evaluation of colonic tissue from SIDS cases for its ability to detoxify H2S.

The changing concept of sudden infant death syndrome: diagnostic coding shifts, controversies regarding the sleeping environment, and new variables to consider in reducing risk

There has been a major decrease in the incidence of sudden infant death syndrome (SIDS) since the American Academy of Pediatrics (AAP) released its recommendation in 1992 that infants be placed down for sleep in a nonprone position. Although the SIDS rate continues to fall, some of the recent decrease of the last several years may be a result of coding shifts to other causes of unexpected infant deaths. Since the AAP published its last statement on SIDS in 2000, several issues have become relevant, including the significant risk of side sleeping position; the AAP no longer recognizes side sleeping as a reasonable alternative to fully supine sleeping. The AAP also stresses the need to avoid redundant soft bedding and soft objects in the infant's sleeping environment, the hazards of adults sleeping with an infant in the same bed, the SIDS risk reduction associated with having infants sleep in the same room as adults and with using pacifiers at the time of sleep, the importance of educating secondary caregivers and neonatology practitioners on the importance of "back to sleep," and strategies to reduce the incidence of positional plagiocephaly associated with supine positioning. This statement reviews the evidence associated with these and other SIDS-related issues and proposes new recommendations for further reducing SIDS risk.

Stable prevalence but changing risk factors for sudden infant death syndrome in child care settings in 2001

OBJECTIVE

A total of 20% of sudden infant death syndrome (SIDS) cases in the 1990s occurred in child care settings. This is much higher than the 8% expected from Census Bureau data. Factors that were associated with child care SIDS included older age; white race; older, more educated mothers; and unaccustomed prone position. Since these findings, much emphasis has been placed on promoting a safe sleep environment in child care. The objectives of this study were to determine the proportion of SIDS occurring in child care in 2001 and to assess risk factors for SIDS in child care.

METHODS

We conducted a retrospective review of all SIDS deaths that occurred in 2001 in 13 US states. Information regarding demographics, SIDS risk factors, and child care arrangements were collected and analyzed. Deaths that occurred in child care were compared with deaths that occurred during parental care.

RESULTS

Of 480 deaths, 79 (16.5%) occurred in child care settings. Of these child care deaths, 36.7% occurred in family child care homes, 17.7% occurred in child care centers, 21.3% occurred in relative care, and 17.7% occurred with a nanny/babysitter at home. Infants in child care were more likely to be older and to die between the hours of 8 am and 4 pm and less likely to be exposed to secondhand smoke. There was no difference in usual, found, or placed sleep position between child care and home deaths. Approximately one half of the infants who died of SIDS in both settings were found prone, and 20% of deaths in both settings were among infants who were unaccustomed to prone sleep.

CONCLUSIONS

The proportion of SIDS deaths in child care has declined slightly but still remains high at 16.5%. Infants in child care are no more likely to be placed or found prone and no more likely to be on an unsafe sleep surface. Educational efforts with child care providers have been effective and should be expanded to unregulated child care providers. In addition, there may be other, yet-unidentified factors in child care that place infants in those settings at higher risk for SIDS.

Sudden infant death syndrome in child care settings in the Netherlands

BACKGROUND

In the Netherlands, there is a very low incidence of sudden infant death syndrome (SIDS) due to effective preventive campaigns.

METHODS

During the period September 1996 to August 2002, nationwide 161 deaths from SIDS (about 85% of all cases of SIDS during that time) were investigated by the Cot Death Committee of the Dutch Paediatric Association.

RESULTS AND DISCUSSION

Over 10% of cases of SIDS took place during some type of child care. From a national survey carried out in 2000/01 information was available on the child care attendance of 2000 Dutch infants aged 3-6 months. Based on the hours usually spent in child care by these infants, the number of similarly aged infants that died from SIDS while attending child care was 4.2 times higher than expected. Remarkably, the prevalence of known risk factors for SIDS, such as sleeping position and parental smoking, was favourable in the SIDS cases in child care settings. The adherence of child care facilities to the safe sleeping recommendations is high in the Netherlands, and no explanation as to why child care settings may be associated with an increased risk of SIDS is apparent. The possibility of other explanations, such as stress and change in routine care, is hypothesised.

Back to sleep: can we influence child care providers?

OBJECTIVE

Despite the fact that 20% of sudden infant death syndrome (SIDS) deaths occur in child care settings, many child care providers continue to be unaware of the association of SIDS and infant sleep position and/or are misinformed as to the risks and benefits of the various sleep positions. The objective of this study was to determine whether an educational program for child care providers regarding SIDS and safe sleep environment is effective in 1) providing basic information and understanding regarding SIDS risk reduction practices, 2) changing child care provider behavior, and 3) promoting development of written sleep position policies.

METHODS

We designed a 60-minute educational in-service for child care providers, to be led by a trained health educator. All providers who attended the in-service were asked to complete surveys before and after the in-service. Surveys assessed provider knowledge, beliefs, and practices. A 6-month follow-up interview was conducted with child care centers that had providers participating in the in-service.

RESULTS

A total of 96 child care providers attended the educational in-service. Providers who were using the supine position exclusively increased from 44.8% to 78.1%. This change in behavior was sustained, with 85% of centers placing infants exclusively supine 6 months after the intervention. Awareness of the American Academy of Pediatrics recommendation of supine as the preferred position for infants increased from 47.9% to 78.1%, and 67.7% of centers continued to recognize supine as the recommended position 6 months later. The percentage of centers that reported written sleep position policies increased from 18.8% to 44.4%.

CONCLUSIONS

A targeted educational in-service for child care providers is effective in increasing awareness and knowledge, changing child care provider behavior, and promoting development of written sleep position policies. This change is sustained over at least a 6-month period.

Nighttime child care: inadequate sudden infant death syndrome risk factor knowledge, practice, and policies

BACKGROUND

Millions of children in the US have parents who work alternative shifts. As a result, extended-hour and nighttime child care centers have increased in number to meet the needs of parents working nonstandard hours. Recognizing that 20% of sudden infant death syndrome (SIDS) occurs in child care settings and that child care providers may place infants prone, it is important to determine sleep position practices in nighttime child care centers.

OBJECTIVE

To determine if nighttime child care centers 1) follow Back to Sleep recommendations; 2) are aware of the need for a safe sleep environment; and 3) have written policies directing proper SIDS risk reduction practices.

DESIGN

A descriptive, cross-sectional survey of licensed child care centers in the US offering evening and nighttime care. All nighttime centers caring for infants <6 months old were recruited for the study.

RESULTS

Out of 153 eligible centers, 110 centers in 27 states completed the survey. Infants were placed prone in 20% of centers, although only 1 center placed infants exclusively prone. Infants slept in cribs in 53.6% of centers, but slept in uncluttered sleep environments in only 18.2% of centers. Smoking was prohibited in 86.4% of centers. The most commonly cited reason for avoiding prone altogether was SIDS risk reduction; however, 10 centers that cited SIDS risk reduction continued to place infants prone at least some of the time, because of parental request or concerns about infant comfort. Over half (59%) of the centers had written policies; however, presence of written policy was not associated with avoidance of prone position. In over one third of centers with written policies, providers were unaware of the content of the policy.

CONCLUSIONS

Twenty percent of nighttime child care centers place infants prone at least some of the time. Most providers who place infants prone do so because of lack of awareness or misinformation about safe sleep environment. Although the Back to Sleep campaign has been effective in communicating the risks of sleeping prone, nonprone positioning is not universal among nighttime child care providers. Additional educational efforts toward child care providers remain necessary. In addition, parents as advocates for their own infants need to be proactive in assuring that safe sleep practices are implemented in child care settings.

Compliance of licensed child care centers with the American Academy of Pediatrics' recommendations for infant sleep positions

Sudden Infant Death Syndrome is an elusive and tragic cause of infant mortality. In 1992, the American Academy of Pediatrics (AAP) recommended that healthy term infants be placed in the supine or lateral positions for sleep, based on research conducted in Europe, Australia, and New Zealand. The AAP modified its recommendation in 1994, indicating a preference for the supine position. Since the initial AAP proposal, national educational programs have worked to encourage parents and health care providers to utilize AAP guidelines. Studies have been done on parental use of the supine position. However, very little information exists about the procedures utilized in licensed child care facilities. A survey of child care providers was conducted to determine the risk for Sudden Infant Death Syndrome, as indicated by rates of compliance with AAP guidelines. Results show that although the majority of the child care providers knew the AAP recommendations, only 14.3% were in complete compliance. We make recommendations for the role of the public health nurse in facilitating compliance in child care centers along with suggestions for future research.

Relationship between infant sleep position and motor development in preterm infants

To determine whether motor development in premature infants varies according to sleep position, we evaluated 213 infants <1750 g birth weight enrolled in the Collaborative Home Infant Monitoring Evaluation (CHIME). At 56 weeks postconceptional age (PCA), sleep position was determined by maternal report, and the Bayley Scales of Infant Development 2nd Edition (BSID-II) were performed. Infants who slept supine were less likely than infants who slept prone to receive credit for maintaining the head elevated to 45 degrees (p = .021), and infants who slept nonprone were less likely than prone sleepers to receive credit for maintaining the head elevated to 90 degrees and lowering with control (p = .001). The Psychomotor and Mental Development Indices at 56 and 92 weeks PCA were not altered by usual sleep position at 56 weeks PCA. In summary, infants sleeping supine are less able to lift the head and lower with control at 56 weeks PCA, but global developmental status was unaffected. Supine sleeping has been associated with decreased risk for sudden infant death syndrome, but compensatory strategies while awake may be needed to avoid delayed acquisition of head control.

Examination of state regulations regarding infants and sleep in licensed child care centers and family child care settings

BACKGROUND

Twenty percent of sudden infant death syndrome (SIDS) occurs in child care settings. Although the incidence of SIDS in the United States has decreased with increased awareness of the risks of prone infant sleeping, smoke exposure, soft bedding, and unsafe sleep environments, avoidance of these risk factors is not universally practiced in child care settings. Advocacy through state child care regulatory agencies and legislative bodies may be effective in more widespread awareness and avoidance of risk factors.

OBJECTIVE

To determine what individual state regulations for licensed child care centers and family child care settings exist regarding: 1) sleep positions for infants under 6 months old, 2) crib safety, 3) bedding safety, and 4) smoking in the facilities.

DESIGN

A descriptive survey of regulations for licensed child care centers and family child care settings in the 50 states and the District of Columbia.

RESULTS

Fifteen states use regulations adopted before publication of the first policy statement of the American Academy of Pediatrics on infant sleep position and SIDS in 1992. Six states require child care centers to place infants nonprone. Sixty-three percent of states require cribs in child care centers to meet at least 1 safety standard, and 45.1% require this in family child care homes. Six states have provisions limiting the use of soft bedding in child care centers, and 4 have such bans for family child care homes. Seventy-one percent of states prohibit smoking in child care centers during hours of operation; 17% of states have similar requirements for family child care homes.

CONCLUSIONS

Many states use child care regulations that were written before the initial policy statements of the American Academy of Pediatrics regarding safe sleep environments for infants. Even those more recently adopted regulations do not adequately address sleep safety for infants. Pediatricians need to become more proactive in promoting safety regulations in child care. Adoption of new regulations can aid in education of child care providers and, thus, improve the safety for infants in child care.

Use of a statewide system to improve health and safety in child care facilities

BACKGROUND

The Early Childhood Education Linkage System (ECELS) in Pennsylvania (PA) models ideals of the national Healthy Child Care America (HCCA) Campaign. Little is known about how child care providers use these newly developed statewide systems and about how users compare with nonusers of such a system.

OBJECTIVES

Our objectives were 1) to assess knowledge and use of ECELS among child care providers in PA, 2) to compare users and nonusers of ECELS with regard to health concerns, advice-seeking preferences, and infant sleep positioning, and 3) to assess satisfaction among users of ECELS.

METHODS

Cross-sectional telephone survey of directors of 400 licensed child care centers (CCCs) and providers of 400 registered family child care homes (FCCHs) in PA.

RESULTS

The proportion of children with certain special health care needs mirrored the prevalence in the national child population. Of the facilities surveyed, 88% of CCCs and 71% of FCCHs had heard of ECELS. Among these, 85% had used ECELS's services in the previous 12 months. Significantly more nonusers than users consulted doctors, whereas more users consulted health professionals from government agencies and used printed materials. Of those who enrolled infants, 46% of users and 41% of nonusers reported placing infants on their backs only to sleep. Users who placed infants on their backs were more likely than nonusers to have a written policy about the correct practice (55% and 26%, respectively; P =.02). Overall, 46% of users and 28% of nonusers reported having a sleep position policy (P =.02). Users were at least 95% satisfied with ECELS's services.

CONCLUSION

This statewide system reached most child care providers surveyed: more outreach is needed to providers in FCCHs. The health concerns, safety practices, and advice-seeking preferences of child care providers described in this article can inform others who are developing similar collaborative services in each state. Further research on the impact of HCCA programs on health and safety practices (such as correct infant sleep positioning) is warranted.

Infant sleep position policies in licensed child care centers after back to sleep campaign

BACKGROUND

Since the Back to Sleep (BTS) campaign was initiated in 1994, the rate of prone sleeping has decreased to approximately 20%. However, child care centers may have an increased rate of prone sleeping in infants. In 1996, a study of licensed child care centers demonstrated that 43% were unaware of the association between sudden infant death syndrome (SIDS) and prone sleeping and that 49% positioned infants prone.

OBJECTIVE

To determine effectiveness of a mailing from the BTS campaign to licensed child care centers by assessing the following: 1) child care center awareness of the recommendations of the American Academy of Pediatrics regarding infant sleep position and 2) implementation of the recommendations of the American Academy of Pediatrics in child care center practice.

DESIGN

A descriptive, cross-sectional survey of licensed child care centers in the metropolitan Washington, DC, region. All licensed child care centers caring for infants <6 months old in Washington, DC, and Montgomery, Prince Georges, Howard, Anne Arundel, Frederick, and Charles Counties in Maryland were recruited for the study.

RESULTS

Out of 236 eligible centers, 172 completed the survey. Seventy-five percent (129) of the centers were aware of recommendations regarding infant sleep position. Infants were placed prone in 27.9% of centers, although only 2.9% placed infants exclusively in the prone position. The most common reasons for avoiding prone position entirely were SIDS risk reduction and licensing regulations. Half of the centers had a written policy regarding sleep position. Twenty centers who were aware of the dangers of prone sleeping continued to placed infants prone at least some of the time, largely because of parental request. Only 56.9% of centers had heard of the BTS campaign despite the mass mailing. The mailing resulted in policy change for 14 centers.

CONCLUSIONS

Since 1996, the percentage of licensed child care centers in the greater Washington, DC, area that are aware of the association between SIDS and infant sleep position has increased from 57% to 75%. In addition, the rate of placing infants prone in these centers has declined from 49% in 1996 to 27.9% in this study. When child care centers are aware of the risk of prone sleeping, the most likely reason for continued prone placement is parental request. Although media and mailings have been largely effective in communicating BTS information to many child care centers, nonprone positioning is not universal among child care providers. Additional educational efforts toward child care providers and parents remain necessary.
