Abstract

This review presents an analysis of the literature on behavioral effects of developmental exposure to nicotine, as assessed in rodent models that mimic the consequences for human offspring of maternal cigarette smoking. Despite the frequency of reports of low birth weight, hyperactivity, cognitive deficits, and psychiatric problems, inconsistencies exist in both the clinical and experimental literature. Confounding socioeconomic and other demographic variables may account for discrepancies in clinical reports, and the choice of developmental exposure period and the method of nicotine administration may explain differences in experimental outcomes. Analysis of a number of variables (e.g., physical, behavioral, and cognitive) shows that fetal exposure to nicotine does not consistently cause growth retardation or decreased birth weight, nor reliably affect motor activity. But combined pre- and neonatal exposure is likely to result in delayed reflex development, global impairments in learning and memory, and an increased incidence of symptoms that model psychiatric illness. There is also support for increased self-administration of nicotine and other drugs of abuse in animals exposed developmentally to nicotine, as well as potent effects on offspring responses to drug challenges. Unlike reports in the clinical literature, sexually dimorphic effects were not evident in most animal models. Possible neuroanatomical and cholinergic mechanisms responsible for behavioral changes are briefly discussed. Statistical and design considerations are provided to increase the translational value of this research and, most importantly, enhance the replicability of reported findings.

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.
