Economic antecedents of prone infant sleep placement among black mothers.
OBJECTIVE
Black infants die from sudden infant death syndrome at twice the incidence observed among non-Hispanic white infants. Explanations for this disparity include a two-fold greater prevalence of prone (i.e., stomach) infant sleep placement among black caregivers. I test the hypothesis that the contraction of state economies may contribute to this disparity by increasing the risk of prone infant sleep placement among black mothers.


METHODS
I retrieved data from the Bureau of Labor Statistics employment series and 33,518 black mothers in 26 states participating in the 1996-2002 Pregnancy Risk Assessment Monitoring System. I use weighted multivariable analyses to control for individual characteristics and state and time trends.


RESULTS
Black mothers exhibit an elevated risk of reporting prone placement one month following statewide declines in employment (adjusted odds ratio for a one percent decline = 1.11, 95% CI 1.01 to 1.22). This risk remains elevated after control for individual variables. In contrast, I find no association between the economy and prone placement among white mothers.


CONCLUSIONS
Statewide economic decline may reduce adherence to the recommended non-prone infant sleep position among black, but not white, mothers. Additional research among black caregivers should determine which mechanisms connect economic downturns to prone infant sleep placement.
