Believe it or not, but worldwide, smoking is still the number one cause of premies. In most of the world, they die. Secondary causes worldwide focus on air pollution.
In the US and UK, causes are more illusive. Read the section on causes in this:
http://en.wikipedia.org/wiki/Premature_birth
Notice there are a number of risk factors: smoking, drugs, nutrition, prenatal care, socio-economic standing of the mom, other births, previous pregnancies terminated, and so on. Being a mom-to-be is serious business.
