Objective:
To identify factors predictive of either lateral or prone infant sleep positioning.
Study Design:
We used data for 11340 mother-infant pairs from the Pregnancy Risk Assessment Monitoring System for infants born in Washington State, 1996 to 2002. We used predictive modeling to identify statistically significant (P < .05) predictors of lateral and prone sleep positioning.
Results:
Factors associated with both high-risk sleep positions included infant's year of birth, maternal race and ethnicity, maternal county of residence, and maternal parity. Mother's being US-born (versus foreign-born) and male infant sex were predictive only of prone sleep positioning. Having Medicaid as primary insurance, receipt of government benefits, low infant gestational age, and low birth weight were predictive only of lateral sleep positioning.
Conclusions:
Factors predictive of either high-risk sleep position should be considered when devising public health intervention strategies for the prevention of SIDS.
