The Research Question would be Are babies born from mothers who smoke during the pregnancy have greater chances of developing low-birth weight , compared to those born from mothers who do not smoke

A study was conducted on pregnant women that belonged to a Maternity Hospital in Haguenau , France , in 1974 . 248 pregnant women that smoked at least five cigarettes a day were defined as `cases , and 196 pregnant women who did not smoke were defined as `controls . Tests conducted on the placenta demonstrated higher incidences of defective trophoblasts in smokers compared to non-smokers . The signs of intrauterine hypoxia , low birth-weight and low placental weight , were also higher in smokers compared to non-smokers . However , the study was not able to establish a relationship between low birth-weight and low placental weight or intrauterine hypoxia (Shipra , A . Et al , 1977

Another study conducted demonstrated that mothers who smoked during one pregnancy had produced infants with lower birth-weight , compared to those infants born during pregnancy when they did not smoke . This was irrespective of the birth and other factors that affect the growth of the unborn baby in the utreus . The reduction in the birth weight was directly associated with the number of cigarettes smoked . Mothers , who smoked less , produced infants on an average 90 grams less than normal whereas those who smoked heavily developed babies on an average 533 grams below normal . Smoking brought about the development of several lesions in the placental due to under-perfusion (which was usually periodic . Besides , pregnancy during smoking was on an average 1 .5 days shorter than without smoking (Naeye , R .L , 1978

A study was also able to demonstrate that women who quit smoking during pregnancy are able to reduce the several risks associated with pregnancy such as low birth-weight , preterm labor , spontaneous abortion etc , and period of breastfeeding also improved (Giglia , R .C . Et al 2006

A study conducted in Johannesburg and Sweto , in 1990 , demonstrated that women who smoked (6 .1 ) and used snuff (7 .5 ) during the pregnancy produced babies who weight an average 2982 grams compared to babies of non-smokers who weighted 3148 grams , on an average . However environmental pollutants (such as passive smoking ) did not significantly adversely affect the birth weight (Steyn , K , Et al , 2006

Another study conducted in Pelotas , Brazil , in 193 , demonstrated that smoking in mothers produced babies on an average… [banner_entry_footer]
