Minimizing
Racial Disparities in Infant Mortality and Preterm Birth
An alarming statistic
is that black infants born in the U.S. have more than double the chance of
dying during their first year of life compared with white infants. (1) The death rate for black infants born here is as
high as it would be if they were born in a developing country. The following facts surely
have something to do with the poor survival rates of black infants in the
U.S.: Twice as many
blacks as whites live in poverty (20% vs. 10%), and nearly twice as many
blacks as whites are among the 45 million people in this country who lack
health insurance (43% vs. 24%). (2, 3)
Infant mortality (death
within the first year of life) is most often a consequence of preterm birth
(before 37 weeks gestation) and low birthweight. It’s no surprise, then, to learn that the
rate of preterm birth is much higher in black women than in white women. In fact, the rate of preterm birth in black
women in America is higher than it is in black women in Africa (18.5% vs.
11.9%). (4) Besides poverty and lack of
access to healthcare, other factors such as psychosocial
stress, bottle-feeding, exposure to lead, intrauterine growth and diet also
play into the health of a mother and her infant. (5)
Racial disparities in infant mortality between blacks and whites
are nothing new, but they’re not improving.
However, a recent three year study in Ohio shows one way they might be
changed: Prenatal participation in the Special Supplemental Nutrition Program
for Women, Infants, and Children (WIC) dramatically reduced the racial
disparity in infant mortality rates among participants. While infant mortality rates among
non-participants was 21% for blacks vs. 7.8% for whites, black women who did
participate had infant mortality rates in line with white participants’ (9.6%
vs. 6.7%). (6)
Other specific factors have
been linked to increased infant mortality, including inadequate prenatal care,
younger maternal age and lower educational levels. It only makes sense, then, that earlier
initiation of prenatal care, and access to risk-appropriate OB and neonatal
care would help improve outcomes in populations at risk. Programs to support parenting of premature
and low birthweight infants should also help improve infant mortality
statistics. (7)
We can also learn from the
European and Scandanavian countries which have laudable, low rates—far lower
than ours—of both preterm birth and neonatal/infant mortality. Their numerous social programs supporting
pregnant women have been instrumental in achieving these results. In many of these countries, paid maternity
leave begins 6-12 weeks before birth, with a specific eye towards minimizing
preterm births. Mothers also have access
to sick leave from their jobs after birth, which may or may not be paid. Prenatal care is comprehensive and free. Other supports include housing and social
supports for more vulnerable populations of women. (8)
Our infant mortality rate is
a national embarrassment—we rank 28th out of 32 countries in the
world, falling behind such countries as the Czech Republic, Slovenia, Estonia,
Greece, Hungary, Poland, Slovakia and even Cuba. (9) The major solution to
improving our infant mortality rate is to first improve our preterm birth rate,
and especially to work towards minimizing the differences in outcomes between
blacks and whites. This will require
reordering our priorities and putting some political muscle into the mix. Money spent upfront to prevent preterm birth
will go a long way towards reducing the current economic burden related to
preterm birth, estimated by the Institute of Medicine in 2006 to be 26 billion
dollars. (10) Hopefully, the emotional
burden of losing a child too early can be lessened as well.
