I, too, would be extremely interested in seeing the real study......not the article that appeared in the newspaper.
You'll have to forgive my cynicism, but often the media portrays scientific studies in their most sensational light, rather than what the study does or does not show.
I think people should be careful with things like this, as it's almost impossible to institute true scientific controls with something like this. Is the u/s the true cause, or could it be that some babies were monitored more closely because of complications that could themselves have influenced this? What about genetic factors and environmental factors (pollution, nutrition, luck) that were beyond anyone's control? How was this accounted for, and controlled, that the scientists felt truly comfortable stating the results with apparently NO caveats or cautions?
Remember...car seats contribute to the death of infants in car crashes...if they are installed wrong or placed in the wrong 'environment', like in front of an airbag or in the front seat. Yet remember how villianized airbags were, a few years ago, when the statement stopped halfway through, without explaining the circumstances and reasons?
It's good to be informed, but serves no one to be alarmist. Mothers, no matter what their choices, get enough crap-guilt heaped upon them. I'll start researching the actual study, though...if I find a link to the real one, I'll let y'all know. If someone finds out offhand what medical journal it was published in, that would be useful info. I tend to like to get my info first hand, rather than have it 'interpreted' for me by people wanting to sell papers, but as there have been concerns about u/s for quite some time, I wouldn't be surprised if there are some side effects. How serious they are for the majority of the population, I dunno.
