Insights
Sudden infant death syndrome (SIDS) mortality is increasing, particularly among non-Hispanic Black infants. Factors like low maternal education and lack of prenatal care are linked to higher SIDS rates and racial disparities.
Area of Science:
- Epidemiology
- Public Health
- Pediatrics
Background:
- Sudden infant death syndrome (ASSB) remains a significant concern, with existing research identifying associated risk factors.
- Racial disparities in ASSB mortality have been observed, necessitating updated analyses.
Purpose of the Study:
- To update trends in ASSB occurrence.
- To determine if previously identified risk factors for ASSB are still relevant.
- To generate new hypotheses regarding ASSB occurrence and racial inequalities in mortality.
Main Methods:
- Utilized National Center for Health Statistics data (ICD-10 Code W75).
- Analyzed race-ethnicity-specific ASSB occurrence from 1999-2016.
- Examined associations between ASSB and maternal/infant factors.
Main Results:
- ASSB mortality significantly increased from 1999-2016 across racial groups, with notable rises for non-Hispanic Black (NHB) infants.
- Previously identified risk factors (e.g., unmarried mothers, low educational attainment, low birth weight) remain associated with ASSB and NHB disparities.
- Geographic variations, midwife-attended births, and teenage mothers suggest new hypotheses for ASSB prevention and racial inequality.
Conclusions:
- Descriptive data highlight increasing ASSB mortality and persistent racial disparities.
- Findings suggest new targets for interventions aimed at reducing ASSB and associated inequalities.
- Further analytic epidemiologic studies are needed to test generated hypotheses.
Abstract:
Objectives (a) Update previous descriptions of trends in ASSB; (b) determine if factors previously associated with ASSB are replicated by updated data; and (c) generate new hypotheses about the occurrence of ASSB and racial inequalities in ASSB mortality. Methods National Center for Health Statistics files (International Classification of Diseases, Tenth Edition) Code W75 to describe race-ethnicity-specific ASSB occurrence. Results (a) ASSB mortality continues to increase significantly; for 1999-2016, 4.4-fold for NHB girls (45.8 per 100,000 in 2016), 3.5-fold for NHB boys (53.8), 2.7-fold for NHW girls (15.8) and 4.0-fold for NHW boys (25.9); (b) F actors previously associated with ASSB (unmarried mothers and mothers with low educational attainment, low infant birth weight, low gestational age, lack of prenatal care, male infant, multiple birth, high birth order) continue to be associated with both overall ASSB and inequalities adversely affecting NHB; (c) (1) geographic differences and similarities in ASSB occurrence support hypotheses related to positive deviance; (2) lower ASSB mortality for births attended by midwives as contrasted to physicians generate hypotheses related to both medical infrastructure and maternal engagement; (3) high rates of ASSB among infants born to teenage mothers generate hypotheses related to the possibility that poor maternal health may be a barrier to ASSB prevention based on education, culture and tradition. Conclusions for Practice These descriptive data may generate new hypotheses and targets for interventions for reducing both ASSB mortality and racial inequalities. Analytic epidemiologic studies designed a priori to do so are required to address these hypotheses.
