Infants of Mexican American descent have lower infant mortality rates (IMRs
) than do non-Hispanic blacks and non-Hispanic whites. Because IMR is used
in allocation methods for primary health care resources, the result could b
e discrimination against Mexican American populations in the distribution o
f resources. This study examined the National Center for Health Statistics'
infant birth and death records, as well as unpublished data from the Burea
u of Primary Health Care. This study found that the low Mexican American IM
Rs ave real and not simply a data anomaly and that inclusion of birth outco
mes has a small and mixed effect on the designation of high-Hispanic areas
as being medically underserved or shout of primary health care professional
s. The authors suggest inclusion of an additional high-Hispanic health indi
cator in the designation criteria for health resources.
