Abortion 'increases risk of premature birth'
This is an unusual study in that it DID control for social class. It also replicates many previous findings. As abortion fills me with horror, I am certainly inclined to accept its conclusions. Scientific honesty impels me to note the weaknesses of the study, however.
Failure to control for both smoking and IQ are large lacunae. Smokers are known to be more sexually promiscuous and greater risk takers generally. So were the smokers in the sample more likely to have abortions? Almost certainly. And smokers are also more likely to have lower birthweight babies. So it could be that we are simply seeing the effects of smoking here, not the effects of abortion.
Similarly, high IQ people are both healthier and most likely better at avoiding unwanted pregnancies. So we could be seeing an IQ effect here too
Abortion appears to increase the chance of giving birth prematurely in a subsequent wanted pregnancy by a third, according to a British study.
Having a surgical abortion could increase the risk of giving birth before 37 weeks by even more than that, found academics at Aberdeen University.
Prof Siladitya Bhattacharya, a gynaecologist, and a team made their conclusions after comparing the second pregnancies of 170,000 women who had previously had an abortion, to 458,000 undergoing their first pregnancies. They found those who had experienced abortions were 33 per cent more likely to subsequently deliver pre-term than those who had never had an abortion.
They were also 44 per cent more likel to give birth extremely prematurely – before 34 weeks.
The academics controlled for social factors like class – known to be have an effect on pre-term delivery – but were unable to take into account smoking because of a lack of information.
The study was presented on Monday at the annual conference of the European Society of Human Reproduction and Embryology (ESHRE) in Stockholm, Sweden.
Prof Bhattacharya’s wife, Dr Sohinee Bhattacharya, an epidemiologist, who gave the presentation, said the physical act of surgical abortions in particular could damage the cervix.
She explained: “When you do a dilatation of the cervix, quite heavy, thick instruments are used. “Especially in younger women, under 25, it is particularly shown to have an effect because the cervix is quite tight.”
Their study showed that women who underwent surgical abortion were 27 per cent more likely to give birth prematurely in their next pregnancy than those who'd had a medical abortion. The team has not yet analysed the overall increased risk of pre-term birth for each type of abortion, compared to women who have not had an abortion.
Prof Bhattacharya noted that women who had undergone an abortion were only as likely to deliver prematurely as those who had previously miscarried. But he said every effort was needed to understand all the factors that led to premature deliveries. “It is important because pre-term birth is a major cause of death - and short and long-term disability - in babies.
“It also causes the NHS millions in terms of neo-natal care and millions more in terms of support for those with continuing disabilities.”

Your conclusions (presented at the top of the article) do not seem to have any relation to the rest of the article.ReplyDelete
You state that "Smokers are known to be more sexually promiscuous and greater risk takers generally" - can you provide a reference that substantiates that statement? You state a conclusion - "So were the smokers in the sample more likely to have abortions? Almost certainly" - some proof of these conclusion would be appreciated.
Another statement you make is that "Similarly, high IQ people are both healthier and most likely better at avoiding unwanted pregnancies. So we could be seeing an IQ effect here too". In my personal experience those with a higher IQ are more interested in the potential rather than the physical now so your assertion that those with higher IQ are healthier seems to contradict the general perception.
As for the statement that (as you put it) "high IQ people are both healthier and most likely better at avoiding unwanted pregnancies" I would respond with that those with a basic sex education would be smart enough to use some sort of birth control (regardless of it is the pill, condoms or a hormone injection) to avoid unwanted pregnancy. A high IQ is not required to decide that this is beneficial - it simply comes down to availability, cost and social stigma.
If you really want to reduce the number of abortions then educate people how to have sex without impregnation - teach boys to use condoms, teach girls to go on the pill or use alternative measures to avoid unwanted pregnancies.
The findings about smokers go back to Eysenck in the '70sReplyDelete
The findings about high IQ people go back to Terman & Oden in the 1920s
"those with a basic sex education would be smart enough.. "
So how come many don't?
