Zusammenfassung

-jährigen Kindern, deren Mütter während der Schwangerschaft Nikotin konsumierten, wurde mit den Leistungen einer Gruppe von 100 nach Alter, Geschlecht und sozioökonomischem Status parallelisierten Kindern nicht rauchender Mütter anhand der Ergebnisse aus dem „Kognitiven Entwicklungstest für das Kindergartenalter“ (KET‐KID) verglichen. Zusätzlich wurden anamnestische Daten durch einen elterlichen Fragebogen erhoben. Ergebnisse: In den Bereichen Psychomotorik, Artikulation, auditives Gedächtnis, Sprachverständnis und Rhythmus zeigen die Kinder, deren Mütter während der Schwangerschaft geraucht hatten, signifikant schwächere Leistungen. Nach Unterteilung in die Gruppen von Kindern leichter Raucherinnen (≤ 9/Tag) vs. Kinder starker Raucherinnen (≥ 10/Tag) zeigten sich dosisabhängig Defizite im auditiven Gedächtnis. Schlussfolgerung: Selbst ein geringer täglicher Nikotinkonsum während der Schwangerschaft verursacht kognitive Defizite beim Kind, die sich auch im Kindergartenalter nachweisen lassen. Daraus lässt sich ein deutlicher Appell an werdende Mütter formulieren, mit Beginn einer Schwangerschaft vollständig auf das Rauchen zu verzichten!

Abstract

Purpose: Aim of the study was to examine to what extent children whose mothers smoked during pregnancy show cognitive deficits at preschool age. Material and Methods: The cognitive developmental stage of 100 children aged from three to six and a half-years whose mothers smoked during pregnancy was compared to 100 children matched for age, sex, and socioeconomic state whose mothers did not smoke during pregnancy; all children were assessed using the “Kognitiver Entwicklungstest für das Kindergartenalter” [cognitive developmental test for children of kindergarten age] (KET-KID). Anamnestic data was collected with the help of parental questionnaires. Results: The performance of children whose mothers had smoked during pregnancy was significantly poorer with regard to psychomotor activities, articulation, auditory memory, speech perception, and rhythm. The group of children whose mothers had smoked was differentiated further into two groups: a group of children born to mild (< 9/day) and a group of children born to heavy (≥ 10/day) smokers. Dose-dependent deficits in auditory memory performance were found in the children from the heavy smokers group. Conclusion: Children tested at preschool age whose mothers consumed nicotine during pregnancy show significant cognitive impairments even after small daily doses of nicotine. Pregnant women need to be clearly urged to stop smoking completely at the start of pregnancy and not to smoke throughout the pregnancy.
