A new systematic review and meta-analysis published in the scientific journal jaraba and University of Bristol-led researchers have shown that smoking in utero is associated with attention deficit hyperactivity disorder in children (ADHD) but it is unlikely to be the cause.

Numerous studies have shown that maternal smoking during pregnancy may contribute to the development of ADHD; however, it is not known from these studies whether this indicates a positive or negative impact on factors such as social status, education, income and age. This new review attempts to find the answer to this question.

The study looked at 46 previous studies that looked at the association between smoking cessation and the generation of ADHD diagnosis. The special review includes a computational analysis of the effects of genetics, in addition to conventional methods.

Some of these studies have low risk of bias (meaning they may not give the wrong results) and have been able to assess the effects of genetics. These studies suggest that bed rest plays an important role in the association of ADHD offspring with smoking. This is supported by a recent retrospective study of genetic predisposition which also concluded that the association between smoking cessation and ADHD was explained by genetic predisposition.

Lead author Dr. Elis Haan, a Distinguished Research Fellow at the Bristol School of Social Sciences, said: regular review showed that there was no adverse effect between smoking and offspring of ADHD diagnosis. However, pregnant women They should still be advised not to smoke during pregnancy, as smoking before childbirth does illa masu illa on other health outcomes. ”
