That was auto correct - it was meant to be ‘serious’.
I read the study and it came across as being very defensive. Almost as if it had some preconceived agenda…
I presume this is the section you are referring to. I couldn’t see any citations for the comparison in turn but the thing that jumped out at me was that while they admitted that risk doubled after cousin marriage, they then didn’t give a baseline or any contextual info about the claim that the risks for white British women were also ‘double’. Double what? They are talking about 2 entirely different cohorts. Their figures also contradict other studies that found 12% infant mortality in repeated cousin marriages through the generations.
The figure that I found was that the additional risk to white women over 35 was 0.89 so it appears that the baseline risk factor is 0.445. It’s comparing completely different things and utterly dishonest.
They also claim that white women having babies over 35 is a ‘cultural practice’. No it isn’t. The demands of careers and government may be pushing women to have children later but it is not a ‘cultural practice’. In any case, if it had an equal risk to cousin marriage I’m sure words would be had and older mothers would be shamed for putting their kids health at risk.
You point out that cousin marriage in Bradford is declining - why? If it’s so risk free and desirable, why is it happening less? It would be even lower if we made it illegal. Then it would be classed as incest.
I am very worried that medical care and society are moving backwards. We seem to be encouraging people to continue with a practice that we KNOW creates health issues. These people might get screening but that doesn’t necessarily pick up all possibilities so then what? Are we deliberately creating a situation where there will be more abortion required ?
In each pregnancy there will be a 25% chance that this mutation is co-inherited by their offspring, resulting in the expression of the disorder. There also is a wider risk of an adverse impact on biological fitness through generational effects (so-called inbreeding depression).
Born in Bradford provides the most definitive UK evidence of risk of congenital anomalies.
After allowing for risk factors such as age, obesity and smoking, the risk of congenital anomalies was doubled (3% to 6%) in first cousin marriages and explained 30% of genetic disorders.
However the risk to the child they give birth to also doubled in White British women over the age of 34 years.
At this point, it is important to mention that just like a cousin marriage is a cultural practice in Asian/British Pakistanis heritage, resulting in increasing risk factors for congenital anomalies, so too is choosing to give birth at or after the age 34 in White British women/couples.
