Cigarette Smoking Associated With Delayed Conception

Baird, Donna Day·1985·JAMA: The Journal of the American Medical Association

Abstract

We conducted an epidemiologic study to test the hypothesis that women who smoke have reduced fertility. Data on smoking history and number of noncontracepting cycles until conception were collected from 678 pregnant women. Thirty-eight percent of nonsmokers conceived in their first cycle compared with 28% of smokers. Smokers were 3.4 times more likely to have taken greater than a year to conceive compared with nonsmokers. After adjusting for potential confounding variables by Cox proportional hazards regression, fertility of smokers was estimated to be 72% of the fertility of nonsmokers. Heavy smokers experienced lower fertility than did light smokers (57% and 75% of the pregnancy rate of nonsmokers, respectively). Fertility was not affected by the husband's smoking. These data provide evidence that reduced fertility should be added to the growing list of reproductive hazards of cigarette smoking.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
