There are all manners of reality, and one can find so-called facts to support most any view. But some things simply need further explanation. While I don't particularly think Wikipedia is a the best source of information, it can provide a starting point when researching a given subject. If anyone really cares to fathom the actual causes of infant mortality here in the U.S., they will get an overview at --
http://en.wikipedia.org/wiki/Infant_mortality
Clearly the myriad of reasons include a lack of health care, but much of that is simply out of poor choices and ignorance (about what is available for free).
For starters, here's one statement from the Wikipedia site -- "In the United States a primary determinant of infant mortality risk is infant birth weight with lower birth weights increasing the risk of infant mortality. The determinants of low birth weight include socio-economic, psychological, behaviorial and environmental factors."
Here's another: "Infant mortality due to low birth weight is usually a direct cause stemming from other medical complications such as preterm birth, poor maternal nutritional status, lack of prenatal care, maternal sickness during pregnancy, and an unhygienic home environments.[3] Along with birth weight, period of gestation makes up the two most important predictors of and infant's chances of survival and their overall health."
And still more: "According to the New England Journal of Medicine “in the past two decades, the infant mortality rate (deaths under one year of age per thousand live births) in the United States has declined sharply.” Low birth weights from African American mothers remain twice as high as that of white women. LBW may be the leading cause of infant deaths, and it is greatly preventable. Although it is preventable, the solutions may not be the easiest but effective programs to help prevent LBW are a combination of health care, education, environment, mental modification and public policy, influencing a culture supporting lifestyle. [9] Preterm birth is the leading cause of newborn deaths worldwide.[10] Even though America excels past many other countries in the care and saving of premature infants, the percentage of American woman who deliver prematurely is comparable to those in developing countries. Reasons for this include teenage pregnancy, increase in pregnant mothers over the age of thirty five, increase in the use of in-vitro fertilization which increases the risk of multiple births, obesity and diabetes. Also, women who do not have access to health care are less likely to visit a doctor, therefore increasing their risk of delivering prematurely."
Like free public education, health care is available, but some, for whatever reasons, choose otherwise. Just watch the Jerry Springer show for some prime examples.
