Women who have had an abortion or miscarriage are more likely to give birth to premature or underweight babies, according to research.
I know it\’s only the newspaper report, not the paper, but I wonder whether they controlled for social class (or wealth if you prefer). Way back when (this is 50s and 60s information being processed now) was there a link betwen a miscarriage and or abortion and the wealth (or social class) of the pregnant woman? For we know that there is a link between social class (or wealth) and the risks of having an underweight child. If so, are the links between miscarriage (and abortion) and underweight simply both reflecting the same underlying cause, the wealth (or social class) of the mother?
As I say, I dunno: it would be remarkable if that hypothesis had not been tested.
