smoking during pregnancy statistics
My friend wont listen to me about not smoking while pregnant.?

So my friend is 15 weeks pregnant and she wont stop smoking. She says she doesn’t know anyone who smoked during their pregnancy that had problems with the pregnancy or the baby. I was wondering how many ladies smoke/smoked while pregnant and what was the outcome? Did you have complications during the pregnancy, was/is your baby healthy? Or any ladies that know someone who smoked. What was the effect it had on the mother and baby? I don’t what statistics, I want real personal stories please. Thanks for your time.
To all of you who are giving thumbs down, at least they are giving me real stories of real people and not just what the think.

I am a labor nurse and have seen women who have smoked who have had healthy babies, and I have seen women who have had preterm labor, delivered small for gestational age babies, babies that go have difficulty transitioning at birth including low oxygen saturations and trouble managing blood sugars, etc., and the only risk factor was their smoking. It’s a gamble. You never know what you’re going to get. If she wants to take that risk, that’s her decision.

Women Smokers Warned Of Fetal And Infant Risks – Quit Smoking Today

There is strong evidence that pregnant women who smoke cigarettes are thereby increasing the risk of death of their babies, a Public Health Service report said.  The report contains the strongest statement on the risks of smoking in pregnancy ever made by the Public Health Service.  “Numerous retrospective and prospective studies have revealed a statistically significant relationship between cigarette smoking and an elevated mortality risk among the infants of smokers,” says the report.

The document also raised doubts concerning the safety of the little cigars that have become increasingly popular.  Many people can inhale these much as they do cigarettes, the Public Health Service reported, and those who do will probably face increased risks of the lung and heart problems that have been linked to cigarette smoking.  Smokers of pipes and large cigars were told they face some health risks too, but the report made its strongest attack against cigarettes and was particularly strong concerning the risks in pregnancy. 

It said several lines of evidence were accumulating to show “a strong, probably casual association between cigarette smoking and higher late fetal and infant mortality among smokers’ infants.”  Basically, that means still-births and deaths during the first few days of life.

The report said that several thousand stillbirths a year in the United States can probably be accounted for by the smoking habits of the women involved. The pediatrician who wrote that section of the report noted that the number was roughly equal to two-thirds of all the deaths from accidents in Americans aged one to 14.  Accidents are the leading cause of death in that age group.

Among the several hundred references cited in the Public Health Service document was a British report showing that smoking mothers had a stillbirth rate 30 per cent higher than nonsmokers and an infant death rate for the first few days after birth 26 percent higher than mothers who do not use cigarettes.  The report also said new data suggests that the woman who gives up smoking by the fourth month of her pregnancy eliminates the heightened risk for her unborn baby.

It has been known for a while that women who smoke cigarettes bear children with a lower average birth-weight than babies of nonsmokers.  The Public Health Service document said every investigator who had examined this relationship had confirmed it.  Some studies have also found a higher mortality rate among infants of smoking mothers, while others have not.  Thus there has been controversy and confusion over the significance of the findings.  This report puts firth what it feels is a probably explanation of much of the past discrepancies.  For example, the report said the small babies of smoking women appeared to be small for their age, but not premature in calendar and developmental sense.  Prematurity – meaning birth before full development – involves a strong risk.  Therefore, the report argues, a premature baby of a nonsmoking mother may sometimes be at greater risk than a small, but mature baby of a smoking mother, but this does not invalidate the case against smoking.

Furthermore, in the United States, the statistics show that women of lower socio-economic status and women who have a previous history of unsuccessful pregnancy have greater than average risks of stillbirth or early infant deaths.  Although cigarette smoking exerts an independent influence of its own, this can be hidden or influenced by the other factors, the report said.  Thus these other factors must be taken into account in seeking clear evidence for the effect of cigarette smoking by itself.

The report said that three major studies have now done this and show a “highly significant independent association between smoking and mortality.”

Of the questions of spontaneous abortion and birth defects, the report said there was not enough evidence to allow any firm conclusions.  This document also cited animal studies showing that exposure to the chemicals in cigarette smoke can retard fetal growth or cause stillbirths.

Margin of error – Statistics question?

I am quite stuck on this question:

Researchers are interested in factors involved with low birth weight deliveries at an obstetrics clinic. In one year there were 18 low birth weight deliveries to 32 mothers who smoked during pregnancy, compared to 28 low birth weight deliveries to 63 mothers who did not. The margin of error in a 95% confidence interval for the difference in proportions of low birth weight deliveries between mothers who smoked during pregnancy and those who didn’t is:

Could you please explain exactly how to do it and why, I am not very good at statistics and am trying to learn. Thanks!

Hahaha doing stat1201 as well?

Dw it took me a while to figure this out as well.

After time wasted searching through the net I found this formula that are associated with margin of error in proportion. It is :

Margin of error difference = 1.96 * sqrt of (p1*q1/n1 + p2*q2/n2)

p = the percentage of the distribution, in this case p1 = 18/32 = 0.5625 and p2 = 28/63 = 0.4444

q = 1 – p

so subbing in all those values we get the margin of error as 0.211

That is one stat quiz question done for you

The title track is probably the stronge…
