What is Driving the US Prematurity Rate? $$$?

This past November, the CDC published yet again a scathing report card for moms and their yet again higher premature delivery rate, the reason for the US infant mortality rate being worse than most developed countries both in Europe and Asia. 21 countries rate better than the US.
Premature delivery is blamed on deficient prenatal care, obesity, smoking, early C-section, induced labor and fertility treatments. Even though that’s not the whole story, and all of these are preventable, at least to a degree. Moms low on the socioeconomic scale does not get enough prenatal care. This could be minimized if health insurance coverage for maternity care was more affordable. Obesity: absolutely preventable if women exercised more and ate healthier foods. Obesity also starts in the womb for the child if mom eats too much or too little while pregnant. Smoking; definitely preventable! No woman in this day and age should be smoking. No man should be smoking near a pregnant woman. Early C-sections for any other reason than medical necessity should be banned. Induced labor: for any reason other than medical necessity should be banned. Fertility treatments are a necessity for many women and makes focusing on maternal health so much more important, especially if mom is carrying multiple babies. It is not necessarily the fertility treatments that cause premature birth; it is the lack of good health habits in the mother. However, no woman should be allowed to carry more than three, as the health problems created for the babies are too great. Moms are having a tough enough time carrying one healthy baby, 4 or more is impossible. Our number one priority must be that of the health of the babies.
However, even “high risk” moms can have full term pregnancies if proper care is taken to exercise and eat right. In 17 years, I’ve seen many “high risk” moms deliver full term; twins, placenta previa, incompetent cervix, diabetes, hypertension, sever obesity, etc….with proper exercise and nutrition.
With the preemie rate now at almost 13% and rising, we need to focus on the “Lifestyle Factors” of women to prevent premature babies. A healthy vaginal full term delivery cost about $1,500, a C-section can cost $5,000-15,000. The first year of a healthy child costs about $5,000, and the first year of a preemie can cost up to $1.5 million. Not counting food, clothing, diapers etc…
In the last week, several articles were published on how micronutrients reduce prematurity and infant mortality (micronutrient: all individual vitamins and minerals, macronutrient: carbs, protein and fats) , omega fatty acid fish oils are needed for a healthy baby, Vitamin C, D and B vitamins are needed while pregnant, moms veggie rich diet helps baby prevent diabetes, prenatal exercise prevents premature delivery, and even the American Psychological Association came out with “A little know epidemic”: Stress may account for many preterm births.
Stress can be a big problem in pregnancy and can be minimized with exercise, meditation and proper eating and sunning habits. Exercise, meditation, B vitamins, vitamin D (sunshine) and Omega fish oils all improve stress and possible depression levels. Both stress and nutrient deficiencies are major causes of preeclampsia and prematurity, and must be addressed. Moms must exercise, eat better and take good complete, prenatal supplements. Unfortunately most women take prescription vitamins that only contain half of the needed nutrients and in synthetic form rather than natural forms as the synthetic versions are less expensive. Many moms are unduly scared of fish and therefore deficient in omega fatty acids needed for a healthy baby. Vegan source
