Most of our comments--in fact, all our comments--are based on scientific studies, not studies that are necessarily done by us, but that are done by the research community at large.
To my knowledge and my awareness of these research studies, they haven't looked at that. It's a really interesting point. I've never seen premature babies being singled out as a particular group in epidemiological studies. It makes sense that they might be more susceptible, but I can't answer that question. With new technologies, of course, they're able to bring these babies along to have healthy lungs. Later on in their life, I don't know if they would be more susceptible to acquiring asthma or to having greater susceptibilities to air pollution. It's an interesting point.
We know that people who smoke have smaller babies, and they might be premature, but that's the only connection I can see with that.
