Dangers of delaying motherhood until 30: Don’t think the risks begin at 35, say researchers

…and if (like many women today) you are unable to get a husband before the age of thirty, visit a sperm bank and get pregnant out of wedlock? Its an innocent question here.

Please understand that I have absolutely no moral qualms against women who opt to have and raise their children out of wedlock. I just happen to believe the task of child rearing is so enormous that having a good support system in the shape of a life partner is a tremendous help (except the person is a drunk who is perpetually high with pedophilic tendencies).

You see these researchers just keep contradicting themselves. Some months ago I brought you one researcher’s rather controversial assurances that age has very little effect on a woman’s fertility. Now this. How many women  are deliberately putting off pregnancy? I think having those figures would help tremendously.

Women who delay having children enter a ‘risk  zone’ of problems in their early thirties, researchers say – much earlier than  was previously thought.

The risk of problems such as premature and  stillbirth rises by as much as 20 per cent for women aged between 30 and 34,  compared with those having babies in their late twenties.

First-time mothers have previously been told  they are at high risk above the age of 35, but more and more women are putting  off having children until their thirties.

Professor Ulla Waldenström, who led the  study, said: ‘To our surprise we found an absolute increase in risk for negative  effects on pregnancy outcomes in the age group 30-34. These are independent of  the effects of smoking and being overweight, which, when combined, lead to an  even greater risk.’ In England and  Wales the average age at first birth was 27.9 years in 2011 – up 1.3 years in a  decade – and the average age of all mothers was almost 30.

Some of the country’s leading obstetricians  and fertility specialists have warned that women who put off having children  until their thirties are ‘defying nature’ and may not become mothers at all  because of increased rates of risk and infertility.

Professor Waldenström’s team, from the  Karolinska Institute in Stockholm and the University of Bergen looked at data  from around one million first-time mothers in Sweden and Norway. They compared the results of pregnancy in first-time  mothers over the age of 30 with those aged 25 to 29.

The results showed that for women in their  early thirties, there was a one-fifth higher risk of giving birth very  prematurely – during weeks 22 to 31 of pregnancy – or having a stillbirth. There  was also a higher risk that the unborn baby’s growth would be restricted and  that the baby would die.

First-time mothers in this age group were not  previously seen as at risk.

Smoking and being overweight pushed up the  risks of pre-term birth, stillbirth and neonatal mortality to the same level as  that for women aged 35-39, said the report in the scientific journal Obstetrics  and Gynecology.

Professor Waldenström said: ‘For women  individually, the risk is small, but for society at large there will be a  significant number of “unnecessary” complications with so many women having  children just after 30.

‘It would therefore be advisable to inform  both women and men, even at schools, of how important age is to child  birth.’

‘Biologically the best time is probably 20 to  30,’ she added.

Prof Waldenström said many women wanted more  than one child, which meant the age of the first was important.

She said the physiological effect of ageing  on the womb and placenta was likely to explain the higher rates of  complications.
