And yet, Katz said, "the claim they make is probably valid, because it jibes with many previous studies showing the harmful effects of smoking during pregnancy, by anyone in the household."
"Any smoke in the environment is bad," Katz said. He cited a previous study that showed an increased risk of cleft palate among children of smokers, even if the mothers themselves did not smoke. "It's not by any mysterious way, just by inhaling," Katz said. "That is why smoke-free environments are desirable."

There was one pleasant surprise in doing a study of smoking during pregnancy in the Netherlands, Uiterwaal said. "The smoking rate of mothers in pregnancy of 29 percent in the early 1970s that we found in the present study has dropped to some 4 to 5 percent to date in the Netherlands," he said. "A very fortunate drop from a public health perspective, but it will make this issue more difficult to study at present."
Current estimates are that about 10 percent of American women smoke during pregnancy.
