Abstract:  Herein I briefly overview the Infant Mortality Rate (IMR) within the United States. Initially, I discuss specific causes of infant death and then, contributing factors which put babies at risk. Next, the distribution of various IMR is surveyed on a state to state basis.  States possessing the ten highest infant mortality rates are discussed, including possible reasons for higher IMR.  In addition, those states with the ten lowest IMR are mentioned.  In conclusion, I consider preventative measures for minimizing the number of babies that die each year.

Introduction

        Every eight seconds a baby is born in the United Sates (U.S.), and within one hour four babies die (1).  The infant mortality rate (IMR) measures the rate at which babies die before their first birthday and is calculated per 1,000 live births.  According to government figures 7.2 babies out of every 1,000 born in 1996 died (2, p 6).  Although this figure declines steadily each year and is 406% lower than the 1950 figure (3) the United States IMR is still higher than twenty four other nations (1).  More importantly, the IMR for black U.S. citizens is over twice the rate of white citizens (6.3 and 14.6 respectively) (4, p 9).  The National Commission to Prevent Infant Mortality even calls some regions "disaster areas" (5, p 18).  What are the leading causes of infant death, and what areas within the United States are most affected?  What preventative measures can ensure a child its first birthday?  These questions are addressed herein.  In addition, certain National Standards for Geography are met.

Applicable National Standards

         In 1994 a committee of educators came together with the intent of providing national standards for history and geography students on the elementary and high school level.  Upon graduation from high school, students should master eighteen basic principles.  This paper provides an opportunity for students to know and understand three of these guidelines.  First, students will know how to use maps and graphical tools to acquire, process, and report information (number one of the National Standards).  Hot links connect data presented throughout the text to pie graphs, bar graphs, charts, tables, and a map located at appropriate web sites.  Second, the students will know and understand that people define regions and will be able to use them to interpret the world’s (or the United States) changing complexity (number five of the National Standards).  For various reasons infant mortality rate within the United States is higher among regions in which certain populations live.  Knowledge concerning the distribution of these populations facilitates the students’ understanding of IMR distribution.  Third, the student will know and understand that culture and experience influence people’s perceptions of places and experiences (number six of the National Standards).  People tend to form opinions about other people and places based on their own background and biases. Students must realize and contend with factors that influence their perception, thus avoiding "the dangers of egocentric and ethnocentric stereotyping,..." and engage in "...accurate and sensitive analysis of people, places, and environments (6, p 74).  Social issues must be managed objectively, pure of personal predilections.

Causes and Contributing Factors

         Specific causes of infant deaths are easily determined; however, they vary depending on race. For the U.S. population as a whole congenital anomalies (birth defects) has been the leading cause of infant mortality (7) for more than twenty years.  Heart defects account for the largest percentage of anomalies (31.4 percent) (8).  Premature and unspecified low birthweight rank number two.  For babies born with birthweights less than 1,500 grams the infant mortality rate is 264—89 times the rate of healthy babies (4, p 1).  Sudden infant death syndrome (SIDS) is the third leading cause.  Fourth is respiratory distress syndrome; fifth, maternal complications during pregnancy; sixth, complications due to the placenta, cord, and membranes; seventh, accidents and adverse conditions; eighth, infections specific to the perinatal period. The ninth leading cause of infant mortality is pneumonia and influenza, and finally, the tenth leading cause is intrauterine hypoxia and birth asphyxia.  The order of these causes remains the same for the white and Hispanic population.  However, the leading cause of infant death among the black population is premature birth and unspecified low birthweight.  Steinbrook found that "black or white babies of normal weight with college-educated parents have an equal chance of surviving the first year (9, p 26)."  This study coupled with the fact that after four years of college disparity of  infant mortality rates between whites and blacks (4.2 and 11.3 respectively) still exists emphasizes the fatality of low weight babies.  Although accidents and adverse conditions rank number eight among black Americans, homicide makes the list at number ten (2, p 34).  For American Indians the number one cause of infant death is SIDS (2, p 19).  In addition, the rate of deaths relating to accidents and adverse conditions is 3.6 times higher for American Indians than for white babies (4, p 1).
         Numerous indirect risk factors contribute to infant mortality such as sex of infant, multiple births, maternal age, maternal education, live birth order, martial status, maternal smoking, alcohol abuse and drug abuse, available income, and finally, prenatal care. The following information is derived from MacDorman and Atkinson’s article in the Monthly Vital Statistics Report (4, p 1-24).  Infant mortality rates are higher for boys of all races than for girls.  Multiple births increase the rate of infant death by 522%.  Infants born to mothers under twenty years old have a mortality rate of 10.8, infants born to women forty and over have a mortality rate of 9.0.  Women between the ages of twenty five and thirty four have the lowest infant mortality rate.  In general, maternal education is indirectly proportional to infant death—the higher the education the fewer the deaths. The infant death rate for women with nine to eleven years of education is 10.8.  After four years of college, this rate drops to an astounding 4.7. Short intervals between delivery of one child and conception of another child may contribute to low birthweight and preterm delivery.  In addition, the order in which babies are born into a family affects their survival rate.  The second baby born has the lowest mortality rate (6.8), and beyond the third baby the infant mortality rate rises drastically (9.5-12.7) (4, p 9).  Marital status interacts with many other risk factors, for instance, "economic and social support for the mother; whether or not the pregnancy was wanted; as well as maternal age, educational level, and prenatal care attendance (4, p 6)."  The IMR is nearly twice as high for babies of unmarried women (4, p 6).
       Smoking, alcohol and drug abuse during pregnancy reduces infants’ chances of survival.  Smoking increases infant mortality rate by 162% (4, p 6)! Smoking increases the risk of low birthweight , preterm delivery, and mental retardation.  According to Bond, sixty-three percent of women who quit smoking during pregnancy relapse.  Thus, promoting respiratory illnesses and tripling the risk of SIDS by  exposing their child to passive smoke (10, p 3).  The highest percentage of mothers who smoked during pregnancy is among American Indians(4, p 10)—the only ethnic group of  U.S. citizens whose leading cause of infant death is SIDS (2, p19).  Alcohol and drug abuse lead to deformities, the number one cause of infant death.   Although no statistics relating income and infant mortality rates are found, the effects of inadequate funds are logical.  Without money mothers cannot receive proper nutrition or prenatal assistance; thus increasing the risk of preterm and low birthweight babies, maternal complications during pregnancy, complications due to the placenta, cord, and membranes, infections, and pneumonia and influenza.  Cowley stated, "Poor children are more likely to suffer from low birthweight, more likely to die during the first year of life,..., and less likely to benefit from immunizations or adequate medical care (5, p 21)."
         The risk factors mentioned above are difficult to measure because women with one factor often exhibit other risk factors.  For example,  teenage mothers are more likely to be unmarried, less educated, and have lower incomes.  However, the majority of these factors somehow relate to amount of prenatal care obtained by the mother.  After several years of work, the National Commission to Prevent Infant Mortality concludes that "at least half of the country’s infant deaths could be prevented with better prenatal care...(11, p 8)."  Prenatal care can detect and manage pre-existing maternal medical conditions and provide healthy living advice.  Herman states in an article in the Washington Post Health that "prenatal care alone makes a tremendous difference in the infant mortality rate (12, p 9)."  According to 1995 statistics, prenatal care obtained during the first trimester reduces infant mortality rate 574% (4, p 9)!

State to State Analysis
 
        The National Commission to Prevent Infant Mortality considers certain areas of the United States "disaster areas" (5, p 18).  In 1998 Infant Health Statistics published the 1994 infant mortality rates (IMR) of each state (13), and a demographic map of  national IMR distribution was published on the web by the Annie E. Casey Foundation (14).  As the "infant mortality capital (15, p 15)" of the United States, the District of Columbia has overwhelmingly the highest rate at 18.2 deaths per 1,000 live births (five percent higher than 1993 IMR). Mississippi has the second highest rate at 11.0. Louisiana ranks third with an IMR of 10.6.  Georgia, Alabama, and North Carolina run a close race with infant mortality rates of 10.2, 10.1, and 10.0 respectively.  South Dakota has the seventh highest rate at 9.6.  South Carolina and Illinois tie with an IMR of  9.3.  Arkansas follows closely behind with 9.2.  Why are the infant death rates so high in  these states?  What is the common factor?  Unfortunately, the reason is partially linked to race.
        The majority of the high rates are in states with a large percentage of back Americans.  In fact, Washington D.C. is the only state or would-be state with an African American majority, and as Nicholas Eberstadt states, "It is a well known fact that black babies in America are much more likely to suffer a low birthweight than white ones... (15, p 4, 8)."  The reason for this disparity is not fully understood.  Even after various risk factors are taken into account, Goldenberg and his associates find that black women still may have more low birthweight and premature babies than white women (16, p1317).  Their study includes white women with more risk factors than the black women, and yet, on average the white infants weigh more. This innate characteristic is enhanced when combined with other risk factors.  The California state committee trace the breach in white and black IMR to "conditions present in the black community including poverty, unemployment, single-parent families, and lack of access to proper medical care (17, p A35)," and an article in The New England Journal of Medicine states that more black women have short intervals between pregnancies (18, p 70).  Although many determinants contribute to infant death, the most tell-tell statement comes from Eberstadt.  He states, "The  District [of Columbia] may be one of black America’s most prosperous areas, but it also has one of its worst rates of prenatal care utilization...The portion of black mothers obtaining prenatal care for their babies only in the third trimester, or not at all, is over two-thirds higher in the District than in America as a whole (15, p 9-10)."
        In contrast to Washington D.C. and many southern states, certain New England states and western states have phenomenally low infant mortality rates.  Rhode Island has a substantially lower infant mortality rate than any other state (5.0). Massachusetts is second with an IMR of 6.0. Maine, New Hampshire, Utah, and Washington tie for third at 6.2.  Nevada follows closely with an infant mortality rate of 6.5.  Hawaii, West Virginia, and Wyoming all have the fifth lowest rate of 6.7.  No records could be found to explain these low rates, nor to explain Rhode Island’s 31% decrease in infant deaths (13).

Conclusion

         Every child deserves the chance to live. The number of premature births rises each year (19), and although technology strives to curtail the infant death rate, it cannot save them all.  In addition, simple, inexpensive (in comparison to life support systems) practices are more effective.  The National Commission to Prevent Infant Mortality recommends five basic government provisions:
        1)  guarantee universal coverage and access to services for prenatal care, including outreach, transportation, and translation;
        2)  increase availability of services by opening more school-based clinics and making better use of nurse practitioners and nurse midwives;
        3)  organize services to make everything available in one convenient place;
        4)  provide 100% coverage for all recommended well-baby examinations;
        5)  include more specialists in managed health care plans for at-risk pregnant women and infants with special needs (11, p 8).

        The power of education cannot be over-stressed, nor the effects of money.  Mothers must understand the importance of good nutrition and abstinence from alcohol, smoking, drugs, and other risk factors; they need equal access to clinics, technology, and resources; and they deserve peace of mind that their baby will receive proper care.
        However, the solution to keeping Americas babies alive is not in technology, money, education, nor government intervention.  Washington D.C. serves as a prime example.  Eberstadt makes the following observation concerning Washington D.C.’s high IMR.  He states that according to the U.S. Census Bureau, the poverty and unemployment rate for black Washingtonians is much lower than for the average nationwide African American.  The "proportion of adults twenty-five or older with college degrees is distinctly higher for blacks in the District than for those in the country as a whole," and Washington’s ratio of population to medical doctors is nearly twice the national average (15, p 5-7).  In addition, he notes that "higher food stamp recipience closely corresponds with lower usage of prenatal medical services (15, p 14);" thus government aid is not promoting necessary maternal practices.  In fact, 466 babies each year are born within the United States to mothers who either started prenatal care in the final trimester or did not receive any care at all (1).
        The true determinant of a babies chances of survival most often lie in the parents’ hands.  The most important factor is whether or not the baby is wanted.  Second, the parents/parent must be educated, and actively participate in prenatal care programs and basic hygienic practices.  Third, the parents/parent should consider whether raising and caring for their child is financially reasonable.  The cure to babies dying is, therefore, a lifestyle change.  Children who grow up in unhealthy environments "never understand what is necessary for healthy living (5, p 21)."  Likewise, children who grow up in abusive, dysfunctional environments never understand what life is like outside of those conditions.  Thus the cycle continues.
