Newborn Death Risk Halved at Full Term





The risk is low to begin with, but adding those last three weeks or so halves the actual risk.  Sort of discourages early inducing.  We still live in the age of full term pregnancy and will for some time yet.

However, the prospect of producing a child in an artificial womb or maturation device is certainly appealing in view of the actual trauma inflicted on the mother. Humanity is not well designed and pre modern death rates from live births were no laughing matter.  Research is still fairly slow on this topic, but a protocol that transfers the embryo to an artificial womb after the first trimester and supported the mother with hormonal treatment to imitate the missing pregnancy is no longer impossibility or far fetched. 

It is to be recommended as it avoids Caesarian and all those other nasty complications and leaves the mother physically intact and without any trauma.

Risk of Newborn Death Cut in Half When Pregnancy Lasts 39 Weeks

MAY 23, 2011


The research by a team of investigators from the March of Dimes, the National Institutes of Health and the US Food and Drug Administration found that although the overall risk of death is small, it more than doubles for infants born at 37 weeks of pregnancy, when compared to babies born at 40 weeks, for all races and ethnicities.


In 2006, the infant mortality rate was 1.9 for every 1,000 live births or babies born at 40 weeks of pregnancy. The mortality rate increased to 3.9 per 1,000 when a baby was born just a few weeks earlier at 37 weeks of pregnancy, the study found.

There were 4.1 million births in the United States in 2009 2 fewer deaths per 1000 live births would save 8000 lives.

There are about 160-170 million births per year worldwide. Infant mortality worldwide is about 43 deaths per 1000 About 6.8 million lives could be saved if the near optimal level of infant mortality could be achieved worldwide.


Risk of Newborn Death Cut in Half When Pregnancy Lasts 39 Weeks, New Research Finds

  WHITE PLAINS, N.Y., May 23, 2011 -- Adding just a few more weeks of pregnancy can cut a newborn’s risk of death in half – even if the pregnancy has reached “term” -- adding more evidence to the argument that continuing a pregnancy to at least 39 weeks is crucial to a baby’s health.

         The research by a team of investigators from the March of Dimes, the National Institutes of Health and the US Food and Drug Administration found that although the overall risk of death is small, it more than doubles for infants born at 37 weeks of pregnancy, when compared to babies born at 40 weeks, for all races and ethnicities.

          In 2006, the infant mortality rate was 1.9 for every 1,000 live births for babies born at 40 weeks of pregnancy. The mortality rate increased to 3.9 per 1,000 when a baby was born just a few weeks earlier at 37 weeks of pregnancy, the study found.

          “There is the perception that babies born between 37 and 41 weeks of pregnancy are all born healthy. But this study confirms that even babies born just a week or two early have an increased risk of death,” said Alan R. Fleischman, MD, senior vice president and medical director at the March of Dimes. “It is clear, that regardless of race or ethnicity, every additional week of pregnancy is critical to a baby’s health.”

          While there are times when medical reasons require a baby to be delivered early, an early elective delivery is harmful to a baby and should never be scheduled before 39 or 40 weeks of pregnancy.

          The study titled: “Term pregnancy: a period of heterogeneous risk for infant mortality,” was led by Uma M. Reddy, MD, MPH of the Eunice Kennedy Shriver National Institute of Child Health and Human Development, of the National Institutes of Health, was published in Obstetrics & Gynecology, Vol. 117, No. 6, June 2011.

          Preterm birth is less than 37 completed weeks of pregnancy. Until recently, babies born after 37 weeks of pregnancy were evaluated as a single, homogenous group, the March of Dimes says. The investigators found that early term infants had higher infant and neonatal mortality rates when compared to full term infants for every year from 1995 to 2006. Neonatal infant mortality rates were highest for infants born at 37 weeks of pregnancy, and declined for each additional week until 40 weeks, which had the lowest neonatal death rates. The trend was the same for all races and ethnicities. However, of the infants in the study non-Hispanic black infants had the highest infant mortality rates and the smallest declines at 37 and 38 weeks, the researchers said.

          “Although infant mortality rates overall improved in the past decade, rates for non-Hispanic blacks babies born at 37 or 38 weeks of pregnancy remain unacceptably higher than other racial and ethnic groups,” said Dr. Reddy. “Our results indicate that intervention programs are needed for this high-risk group, as is additional research to understand why non-Hispanic black infants are less likely than other groups to live to celebrate their first birthday.”

          The March of Dimes is the leading nonprofit organization for pregnancy and baby health. With chapters nationwide and its premier event, March for Babies, the March of Dimes works to improve the health of babies by preventing birth defects, premature birth and infant mortality.
