Reports of Injury Risks and Reasons for Choice of Sleep Environments for Infants and Toddlers.

OBJECTIVE: Compare mothers' reports of injuries for infants and toddlers sleeping with crib-bumpers/mesh-liners/no-barriers and reasons for these sleep environment choices. METHODS: A cross-sectional survey of mothers subscribing to a parenting magazine and using crib bumpers (n = 224), mesh liners (n = 262), and no barriers (n = 842). Analyses of four possible injuries (face-covered, climb-out/fall, slat-entrapment, hit-head) including multivariate logistic regression adjusted for missing data/demographics and Chi squared analyses of reasons for mothers' choices. RESULTS: Maternal reports of finding infants/toddlers with face covered had 3.5 times higher adjusted odds (aOR) for crib bumper versus mesh liner use. Breathing difficulties and wedgings were reported for infants/toddlers using crib bumpers but not mesh liners. Climb-outs/falls showed no significant difference in aORs for crib bumpers versus no-barriers and mesh liners versus no barriers. Reports of slat-entrapment were less likely for mothers using crib bumpers and mesh liners than using no barrier (aOR = .28 and .32). Reports of hit-heads were less likely for crib bumpers vs no barrier (aOR = .38) with no significant difference between mesh liners versus no barrier use. Mothers using crib bumpers and mesh liners felt their choice prevented slat-entrapment (89%, 91%); 93.5% of crib bumper users felt their choice prevented hit-heads. Significantly more mesh liner than crib bumper users chose them because "There is no suffocation risk" (64.1% vs. 40.6%), while 83.6% of no-barrier users chose them because "I was concerned about suffocation risk." CONCLUSIONS FOR PRACTICE: Mothers appeared to be more concerned about preventing minor risks than suffocation. Understanding reasons for mothers' use of barriers/no-barriers is important in tailoring counseling for mothers with infants/toddlers.

Crib Bumpers Continue to Cause Infant Deaths: A Need for a New Preventive Approach.

OBJECTIVES: To assess whether clutter (comforters, blankets, pillows, toys) caused bumper deaths and provide an analysis of bumper-related incidents/injuries and their causal mechanisms. STUDY DESIGN: Bumper-related deaths (January 1, 1985, to October 31, 2012) and incidents/injuries (January 1, 1990, to October 31, 2012) were identified from the US Consumer Product Safety Commission (CPSC) databases and classified by mechanism. Statistical analyses include mean age, 95% CIs, χ(2) test for trend, and ANOVA with a paired-comparisons information-criterion post hoc test for age differences among injury mechanisms. RESULTS: There were 3 times more bumper deaths reported in the last 7 years than the 3 previous time periods (χ(2)(3) = 13.5, P ≤ .01). This could be attributable to increased reporting by the states, diagnostic shift, or both, or possibly a true increase in deaths. Bumpers caused 48 suffocations, 67% by a bumper alone, not clutter, and 33% by wedgings between a bumper and another object. The number of CPSC-reported deaths was compared with those from the National Center for the Review and Prevention of Child Deaths, 2008-2011; the latter reported substantially more deaths than CPSC, increasing the total to 77 deaths. Injury mechanisms showed significant differences by age (F4,120 = 3.2, P < .001) and were caused by design, construction, and quality control problems. Eleven injuries were apparent life-threatening events. CONCLUSION: The effectiveness of public health recommendations, industry voluntary standard requirements, and the benefits of crib bumper use were not supported by the data. Study limitations include an undercount of CPSC-reported deaths, lack of denominator information, and voluntary incident reports.

Where should infants sleep? A comparison of risk for suffocation of infants sleeping in cribs, adult beds, and other sleeping locations.

OBJECTIVES: To ascertain whether the number of sudden infant deaths as a result of suffocation in cribs, in adult beds, on sofas or chairs, and on other sleep surfaces was increasing whether attributable to increased reporting, diagnostic shift, or an actual increase in suffocation deaths and to compare the risk of reported accidental suffocation for infants on sleep surfaces designed for infants with the risk on adult beds. METHODS: We reviewed all accidental suffocation deaths among infants < or =11 months of age reported to the United States Consumer Product Safety Commission from 1980 through 1983 and 1995 through 1998. We compared infants' ages and other demographic data, the sleep location and surface used, and the reported mechanism or pattern of death. For 1995-1998, we used data on sleep location from an annual survey of randomly selected households of living infants younger than 8 months, collected as part of the National Infant Sleep Position Study at the National Institute of Child Health and Human Development, to calculate risk for death as a result of suffocation in cribs, in adult beds, and on sofas or chairs. METHODS: The number of reported suffocation deaths by location were compared between the 1980s and 1990s using logistic regression modeling to calculate odds ratios (OR), 95% confidence intervals (CI), and P values. Comparative risks for suffocation deaths on a given sleep surface for infants in the 1990s were examined by calculating rates of death per 100 000 exposed infants and comparing the 95% CI for overlap. RESULTS: From the 1980s, 513 cases of infant suffocation were considered; from the 1990s, 883 cases. The number of reported suffocation deaths in cribs fell from 192 to 107, the number of reported deaths in adult beds increased from 152 to 391, and the number of reported deaths on sofas or chairs increased from 33 to 110. Using cribs as the reference group and adjusting for potential confounders, the multivariate ORs showed that infant deaths in adult beds were 8.1 times more likely to be reported in the 1990s than in the 1980s (95% CI: 3.2-20.3), and infant deaths on sofas and chairs were 17.2 times more likely to be reported in the 1990s than in the 1980s (95% CI: 5.0-59.3). The sleep location of a subset of cases from the 1990s, 348 infants younger than 8 months at death, was compared with the sleep location of 4220 living infants younger than 8 months. The risk of suffocation was approximately 40 times higher for infants in adult beds compared with those in cribs. The increase in risk remained high even when overlying deaths were discounted (32 times higher) or the estimate of rates of bedsharing among living infants doubled (20 times higher). CONCLUSIONS: Reported deaths of infants who suffocated on sleep surfaces other than those designed for infants are increasing. The most conservative estimate showed that the risk of suffocation increased by 20-fold when infants were placed to sleep in adult beds rather than in cribs. The public should be clearly informed of the attendant risks.

Sudden infant death with external airways covered: case-comparison study of 206 deaths in the United States.

OBJECTIVE: To study factors associated with sudden infant deaths occurring with the external airways (ie, nose and mouth) covered by bedding. DESIGN: Case-comparison study of infants dying with vs those dying without the external airways covered. SETTING: Death-scene investigation and reconstruction at the site of death using an infant mannequin; 18 metropolitan areas. PARTICIPANTS: Caregivers for a consecutive sample of infants who died of sudden infant death syndrome (SIDS). Complete data from 206 of 382 eligible cases. MAIN OUTCOME MEASURES: Among infants dying suddenly and unexpectedly, an analysis of whether sociodemographic risk factors for SIDS, sleep practices, or bedding increased the risk of dying with the external airways covered. RESULTS: Data were analyzed by using univariate and 2 types of multivariate risk analysis, logistic regression and latent class. Of the victims, 59 (29%) were found with the external airways covered. Conventional risk factors for SIDS did not affect the risk of death with the external airways covered. Factors increasing the risk of death with the external airways covered included prone sleep position (odds ratio [OR], 2.86) and using soft bedding (OR, 5.28), such as comforters (OR, 2.46) and pillows (OR, 3.31). Infants at low risk for death with the external airways covered slept in the prone position, but rarely on a pillow, comforter, or other bedding that allowed a pocket to form beneath the face. All 9 infants who were positioned supine or on one side for sleep and found with the external airways covered had turned and were found dead in the prone position. CONCLUSIONS: Sudden infant deaths with the external airways covered were common in the United States when most infants slept prone. Soft bedding, including pillows and comforters, increased the risk that an infant who died would be found with the external airways covered. Therefore, these items should not be placed near infants, regardless of the sleep position.
