The global burden of sudden infant death syndrome from 1990 to 2019: a systematic analysis from the Global Burden of Disease study 2019

An Evidence-Based Safe Sleep Program Is Associated With Less Infant Sleep-Related Deaths

BACKGROUND

Sudden unexpected infant death (SUID) is a leading cause of infant mortality in the United States. Hospitals have implemented infant safe sleep programs with varying measures and degrees of success, but few have demonstrated improvements in hospital-based and home safe sleep practices with nurse subject matter experts (SMEs) and community SUID prevention campaigns.

AIMS

This project evaluated the impact of a state-wide, evidence-based infant safe sleep program for birthing hospitals using nurse SMEs and a community awareness campaign on nurse knowledge, safe sleep environments, and trends in infant sleep-related deaths.

METHODS

Between 2016 and 2021, a pre- and post-test quality improvement intervention-based design was used to enroll hospitals and train and embed SMEs to educate peers, conduct practice surveillance and audits, and address practice deviations. A website housed comprehensive resources, and a large-scale community-based social and print media campaign on safe sleep practices occurred. Nurse and practice data from 12 hospitals that fully implemented the program were compared pre- and post-implementation. State-wide survey data for key safe sleep indicators reported by parents were compared from our 12 birthing hospitals to other facilities.

RESULTS

Of trained nurses (N = 902), 83.4% reported making substantial or exceptional progress in being proactive in surveillance of safe sleep environments. Pre- and post-implementation environmental audits showed a significantly higher proportion of infants in safe sleep positions post-implementation (94.3%) than pre-implementation (89.6%) (p = 0.001). Statewide survey data from birth parents discharged from our program hospitals significantly outperformed those discharged from other state facilities. Multi-media campaigns resulted in over 1.4 million impressions on our website. Sleep-related deaths for infants born at four program hospitals dropped 16.1% from 31 in 2018 to 26 in 2021.

LINKING EVIDENCE TO ACTION

A safe sleep program improved hospital-based nurses' knowledge and practice and birth parent's knowledge and behaviors, and it was associated with a decrease in infant sleep-related deaths.

Prevalence of sudden unexpected death of infants and its subcategories in low- or middle-income countries: a systematic review protocol

INTRODUCTION

Infant mortality in low or middle-income countries (LoMICs) is still triple that of high-income countries (HICs), and the high mortality burden regions are also weighed down by a triple or quadruple burden of disease such as HIV and tuberculosis; chronic illness; mental health; injury and violence; and maternal, neonatal and child mortality. Emerging data suggest that the sudden unexpected death in infancy (SUDI) burden in LoMICs is at least 10-fold that in HICs. While ending preventable deaths in the neonatal period has received some global attention, the postnatal period where SUDIs occur is a poorly understood and data-poor area in LoMICs. We propose conducting a systematic review to evaluate the burden and trends of SUDIs in LoMICs since 2004.

METHODS AND ANALYSIS

We will systematically search PubMed, Web of Science, Scopus, African Index Medicus, EBSCOHost, Google Scholar, WHOIS and WHO database to identify studies published from July 2004 until October 2024. Two reviewers will screen titles and abstracts and select full-text articles independently for review. We will use the tool developed by the South African Medical Research Council-Burden of Disease Review Manager (BODRevMan)-to assess the risk of bias for each included study. Risk of bias will be assessed for each included study. Information on the prevalence and/or incidence of SUDI and its subcategories and case definitions will be extracted from each article. Where possible, data on prevalence, incidence and subcategories will be pooled using a random effects meta-analysis to account for variability between estimates. The I2 statistic will establish the level of heterogeneity due to variation in estimates rather than chance. Results will be presented in tables and graphs. The systematic review will be reported according to the PRISMA 2020 checklist.

ETHICS AND DISSEMINATION

Ethical approval is not required as this is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

Use of Practices to Reduce of Sudden Unexpected Infant Death among Caregivers of Opioid Exposed Newborns

OBJECTIVES

Sudden unexpected infant death (SUID) occurs disproportionately among opioid exposed newborns (OENs) compared to those unexposed. The extent that primary caregivers of OENs adhere to SUID-reducing infant care practices is unknown. We examined rates of SUID-reducing practices (smoking cessation, breastfeeding, and safe sleep [supine sleep, room-sharing not bed-sharing, nonuse of soft bedding or objects]) in a pilot sample of caregivers of OENs.

METHODS

We surveyed 50 English-speaking mothers and other primary caregivers of OENs 1-6 months old between 02/2022 and 10/2023. We examined prenatal and postnatal cigarette smoking exposure, breastfeeding initiation and duration, and sleep position (side, back, or stomach), sleep location (bed-sharing, room-sharing not bed-sharing, or separate room), and soft bedding or objects in the infant sleep space.

RESULTS

Thirty-six (72%) of 50 respondents were birth mothers and 14/50 (28%) were other caregivers. Sixty-one percent of infants were exposed to cigarette smoking prenatally (mothers only) and 34% postnatally (41% mothers vs 14% other caregivers). Sixty percent of infants received breast milk ≤4 weeks. Among respondents, 32% placed infants in nonsupine sleep position (36% mothers vs 21% other caregivers), 38% shared a bed with their infant for sleep (47% mothers vs 14% other caregivers), and 30% used soft bedding in the infant sleep space (33% among mothers vs 21% among other caregivers).

CONCLUSIONS

Infant care practices associated with SUID were highly prevalent in our pilot sample of OENs and differed among mothers versus other caregivers. Further investigation and tailored approaches to this population are needed.

The French registry of sudden unexpected death in infancy (SUDI): a 7-year review of available data

The French "OMIN registry" was established in 2015 to collect nationwide standardised data concerning biological, clinical, environmental and social characteristics of sudden unexpected death in infancy (SUDI) and unexpected death in children aged 1-2 years. A biobank has existed since July 2020 to store biological samples for each case. This article aimed to detail (1) a brief history and the objectives of the registry; (2) a description of the methodology used; (3) the first results of the registry, i.e. the main characteristics of the cases included so far; (4) the process for accessing the data for research projects; and (5) issues regarding weakness and improvement and perspectives offered by the registry. On 31 May 2024, 1975 cases were included in the OMIN registry; on 31 December 2022, 4606 biological samples from 176 cases were collected. For each deceased child, different types of data are registered on an electronic case report form: socio-demographic data, personal and familial medical background, environment and feeding data, clinical data, and biological and imaging results. A strict and continuous quality control process is used to ensure the reliability of the data, in parallel with specific actions to improve the exhaustiveness of the registry. The OMIN registry database is one of the largest and the most complete databases on SUDI, especially in Europe, and the first in the world to associate a standardised biological sample collection with it. Perspectives of research provided by our registry are numerous and could be supported by national and international scientific collaborations.

CONCLUSION

 This article details the objectives and methods of the French registry of SUDI. It provides initial results relating to the population included in the register and the procedure for accessing the data.

WHAT IS KNOWN

• In Western Europe, France is one of the countries with the highest SUDI rate, making it the first cause of death of infants between 28 and 364 days. • The development of epidemiological tools on a national and international scale is essential to advance research into the determinants and risk factors of unexpected death in children under 2 years of age.

WHAT IS NEW

• The OMIN registry was created in France in 2015 to collect nationwide standardised social, environmental, clinical, and paraclinical data for cases of unexpected death in children aged 0 to 2 years. • To date, the OMIN registry has included 680 data from almost 2000 children unexpectedly deceased, completed by a biocollection since 2020. • Data from the OMIN registry, unique in its field, are freely available for scientific research teams, after acceptation by the scientific committee of the registry.

Assessing universal considerations in infant mortality across the globe: A descriptive observational study of sudden infant death syndrome knowledge and reduction coverage on YouTube

Background

Sudden unexpected infant death (SUID) remains one of the leading causes of infant mortality worldwide and is largely driven by sudden infant death syndrome (SIDS). Although SIDS has received coverage and examination of content spanning Instagram, Facebook, and Twitter across the published academic literature, there is no study to date that has examined SIDS related content on YouTube.

Methods

This descriptive observational study was conducted from December 2023 through January 2024 and sought to describe the sources, formats and content covered across the 100 widely viewed videos pertaining to SIDS on YouTube.

Results

The majority of the videos published were by organizations (N=64) including healthcare systems, the American Academy of Pediatrics (AAP) and police departments. Several of the widely viewed SIDS-related content was disseminated by professionals (N=42). Multiple videos presented content on the symptomology pertaining to SIDS as well as contributing environmental risk factors. A wide range of resources were depicted as SIDS reduction measures. Notably, there was substantial emphasis on SIDS reduction postnatally across the widely viewed videos. There was limited representation of content on SIDS awareness and reduction outside of the United States.

Conclusion

Clinical, public health, and organizational implications and recommendations are presented to inform future targets for intervention that can harness findings from this study on widely covered and uncovered content to address the totality of risk factors for SIDS. Future directions in health promotion across the SIDS reduction landscape are also reviewed to account for digital spaces globally, thereby contributing towards reducing infant mortality worldwide.

Prenatal and postnatal factors associated with sudden infant death syndrome: an umbrella review of meta-analyses

BACKGROUND

Comprehensive quantitative evidence on the risk and protective factors for sudden infant death syndrome (SIDS) effects is lacking. We investigated the risk and protective factors related to SIDS.

METHODS

We conducted an umbrella review of meta-analyses of observational and interventional studies assessing SIDS-related factors. PubMed/MEDLINE, Embase, EBSCO, and Google Scholar were searched from inception until January 18, 2023. Data extraction, quality assessment, and certainty of evidence were assessed by using A Measurement Tool Assessment Systematic Reviews 2 following PRISMA guidelines. According to observational evidence, credibility was graded and classified by class and quality of evidence (CE; convincing, highly suggestive, suggestive, weak, or not significant). Our study protocol was registered with PROSPERO (CRD42023458696). The risk and protective factors related to SIDS are presented as equivalent odds ratios (eORs).

RESULTS

We identified eight original meta-analyses, including 152 original articles, covering 12 unique risk and protective factors for SIDS across 21 countries/regions and five continents. Several risk factors, including prenatal drug exposure [eOR = 7.84 (95% CI = 4.81-12.79), CE = highly suggestive], prenatal opioid exposure [9.55 (95% CI = 4.87-18.72), CE = suggestive], prenatal methadone exposure [9.52 (95% CI = 3.34-27.10), CE = weak], prenatal cocaine exposure [4.38 (95% CI = 1.95-9.86), CE = weak], prenatal maternal smoking [2.25 (95% CI = 1.95-2.60), CE = highly suggestive], postnatal maternal smoking [1.97 (95% CI = 1.75-2.22), CE = weak], bed sharing [2.89 (95% CI = 1.81-4.60), CE = weak], and infants found with heads covered by bedclothes after last sleep [11.01 (95% CI = 5.40-22.45), CE = suggestive], were identified. On the other hand, three protective factors, namely, breastfeeding [0.57 (95% CI = 0.39-0.83), CE = non-significant], supine sleeping position [0.48 (95% CI = 0.37-0.63), CE = suggestive], and pacifier use [0.44 (95% CI = 0.30-0.65), CE = weak], were also identified.

CONCLUSIONS

Based on the evidence, we propose several risk and protective factors for SIDS. This study suggests the need for further studies on SIDS-related factors supported by weak credibility, no association, or a lack of adequate research.

Global, Regional, and National Burden of Spine Pain, 1990-2019: A Systematic Analysis of the Global Burden of Disease Study 2019

OBJECTIVE

To describe the global, regional, national, and temporal trends in neck pain (NP) and low back pain (LBP) from 1990 to 2019 and analyze associations with age, sex, and sociodemographic index (SDI).

DESIGN

Temporal trends analyses of the Global Burden of Disease 2019 data for global, regional, and national prevalence, incidence, and years lived with disabilities (YLDs) of NP and LBP from 1990 to 2019.

SETTING

Not applicable.

PARTICIPANTS

MAIN OUTCOME MEASURE(S)

The temporal trends in prevalence, incidence, and YLDs of NP and LBP, and associations with age, sex, and SDI.

RESULTS

Globally, the prevalence, incidence, and YLDs of NP and LBP significantly increased; however, the age-standardized rates of NP showed a stable trend, and those of LBP slightly decreased from 1990 to 2019. The burden of NP and LBP was higher in women than in men. Both NP and LBP exhibited similar age-related trends, with the total numbers and rates increasing with age and reaching their highest points in the middle- and old-aged groups, respectively, in 2019. Overall, the prevalence, incidence, and YLDs of NP and LBP were higher in regions with higher SDI over the 3 decades.

CONCLUSIONS

NP and LBP impose significant major public health burden globally. Although both conditions are more frequent in women and middle-aged groups and tend to be prevalent in countries with high SDI, they have distinct temporal and regional patterns. By comprehending temporospatial trends in the disease burden of NP and LBP, policymakers and health care professionals can make future interventions and policies to effectively manage these conditions worldwide as well as to achieve equity in prevention, diagnosis, and treatment.

A study of Samoan, Tongan, Cook Island Māori, and Niuean infant care practices in the Growing Up in New Zealand study

BACKGROUND

Despite a low rate of infant mortality, Aotearoa New Zealand has a high rate of Sudden Unexpected Death in Infants (SUDI), with disproportionate impact for Pacific infants. This study explored the infant care practices, factors and relationships associated with increased risk of SUDI amongst Tongan, Samoan, Cook Islands Māori, and Niuean mothers in New Zealand, to inform evidence-based interventions for reducing the incidence of SUDI for Pacific families and their children.

METHODS

Analysis comprised of data collected in 2009-2010 from 1089 Samoan, Tongan, Cook Islands Māori and Niuean mothers enrolled in the Growing Up in New Zealand longitudinal cohort study. The sleeping environment (bed-sharing and sleep position) of the infants was assessed at 6 weeks. Multivariable logistic regression analysis were conducted, controlling for sociodemographic factors to explore the association between selected maternal and pregnancy support and environment factors and the sleeping environment for infants.

RESULTS

Mothers who converse in languages other than English at home, and mothers who consulted alternative practitioners were less likely to follow guidelines for infant sleeping position. Similarly language, smoking, alcohol, household dwelling, crowding and access to a family doctor or GP were associated with mothers following guidelines for bed-sharing.

CONCLUSION

The impact of SUDI on Pacific infants may be lessened or prevented if communication about risk factors is more inclusive of diverse ethnic, cultural worldviews, and languages. Societal structural issues such as access to affordable housing is also important. This research suggests a need for more targeted or tailored interventions which promote safe sleeping and reduce rates of SUDI in a culturally respectful and meaningful way for Pasifika communities in Aotearoa, New Zealand.
