Smoking during Pregnancy May Up ADHD Risk among Offspring

Smoking during Pregnancy May Up ADHD Risk among Offspring

Maternal smoking during pregnancy can significantly increase the risk of attention deficit hyperactivity disorder (ADHD) among offspring, reports a new study.

The higher the cotinine levels were in the mother's blood during pregnancy, the greater was the child's risk of developing ADHD later in life, showed an epidemiological study conducted by the Research Centre for Child Psychiatry at the University of Turku in Finland.

Globally, it is the first study in which the connection between fetal nicotine exposure and diagnosis of ADHD was shown by measuring cotinine levels from pregnant maternal serum specimens.

Despite its proven negative effects on fetal development, smoking during pregnancy remains a significant public health issue. During 2017, approximately 12.5 percent of all pregnant women in Finland smoked during pregnancy, and 7 percent continued to smoke throughout their pregnancy.

"Exposure to maternal smoking is associated with various adverse perinatal outcomes. An association between maternal smoking and offspring ADHD has been shown in several studies. However, the causality of the association has been questioned to be mostly due to familial confounding," says Adjunct Professor Roshan Chudal from the Research Centre for Child Psychiatry at the University of Turku.

"All previous studies on the topic were based on maternal self-report of smoking that has been shown to underestimate the true rates of smoking. The disclosure of smoking is even lower among pregnant smokers," continues Dr. Chudal.

Cotinine Reveals Connection between Smoking and Offspring ADHD

Cotinine is the biomarker indicating nicotine exposure. This includes active smoking as well as nicotine exposure from other sources such as nicotine replacement therapy or passive smoking. Measuring cotinine levels from maternal serum specimens collected during pregnancy, this study investigated the association between nicotine exposure during pregnancy and offspring ADHD.

This study included 1,079 ADHD cases and an equal number of matched controls born between 1998 and 1999. Maternal cotinine levels were measured from maternal serum specimens collected during the first and second trimesters of pregnancy and archived in the national biobank. The strength of the research is the availability of valuable information from the Finnish Maternity Cohort biobank (FMC).

"In this first nationwide study using maternal cotinine levels, we report a strong association between prenatal nicotine exposure and offspring ADHD," says Professor Andre Sourander, the leader of the research group from the Research Centre for Child Psychiatry.

The World Health Organization (WHO) considers smoking one of the main public health concerns worldwide.

"Given the high prevalence of both smoking during pregnancy and ADHD among children, these findings warrant future studies on the interplay between maternal smoking and environmental, genetic, and epigenetic factors," observes Professor Sourander.
