Szoptasson-e a dohányzó anya?

Közismert, hogy a dohányzás számos egészségügyi kockázattal jár az anya, a magzat és a megszületett gyermek egészségére nézve. Addiktív természeténél fogva azonban a dohányzásról nem könnyű leszokni, és azoknak, akik megpróbálják, csak kis százaléka jár sikerrel. A várandósság általában elég erős motiváció a nők számára, hogy leszokjanak a dohányzásról, sokan azonban nem képesek lemondani a cigarettáról, és vannak, akik újra kezdik a dohányzást a gyermek megszületése után.

Azoknál a gyermekeknél, akik dohányzó családban élnek, a légúti fertőzések gyakrabban fordulnak elő, mint a nem dohányzó szülők gyermekeinél. A tanulmányok szerint a szoptatás védelmet nyújt ezeknek a gyermekeknek a passzív dohányzás okozta ártalommal szemben: azoknál a csecsemőknél, akiknek az édesanyja a szülés után dohányzott, kevesebb légúti megbetegedés fordult elő, ha a baba szopott, mint ha mesterségesen táplálták.

Nicotine in breast milk influences heart rate variability in the infant

Anders Dahlström, Christina Ebersjö, Bo Lundell

Acta Paediatr. 2008 Aug;97(8):1075-9.

Abstract

Aim: To study the effects of postnatal exposure to nicotine on the regulation of heart rate and blood pressure in infants.

Subjects and Methods: Thirty-eight mother–infant pairs were studied. Twenty nonsmoking and 18 smoking (2–20 cigarettes per day) mothers were included. All infants were healthy, exclusively breastfed and their postnatal age was 6 weeks. During a home visit infant’s urine and mothers’ milk were sampled and concentrations of nicotine and cotinine were analyzed. Infants’ electrocardiogram (ECG) were recorded, sleep state documented and blood pressure during sleep was measured. Heart rate variability (HRV) was calculated with spectral analysis of R–R intervals.

Abstract

Introduction The relationship between tobacco smoking in pregnancy and breastfeeding is of public health importance. The present birth cohort study provided the opportunity to investigate whether the negative relationship between passive smoking measured by the cotinine concentrations in maternal blood at delivery and breastfeeding in postpartum could also be confirmed in nonsmoking mothers.

Materials and methods The study sample included 441 healthy pregnant women who were recruited in the first and second trimester of pregnancy.

Breastfeeding and Smoking: Short-term Effects on Infant Feeding and Sleep

Julie A. Mennella, PhD, Lauren M. Yourshaw, BA and Lindsay K. Morgan

PEDIATRICS Vol. 120 No. 3 September 2007, pp. 497-502

Abstract

OBJECTIVE. The present experimental study was designed to determine how breastfeeding from a mother who smokes affects infants in the short-term.

METHODS. Fifteen mother-infant dyads were tested on 2 days separated by 1 week. Mothers smoked (not in the presence of their infants) on one test day and refrained from smoking on the other. For the next 3.5 hours, infants breastfed on demand. Sleep and activity patterns were monitored by placing an actigraph on the infants’ leg, and milk intake was determined by weighing the infants before and after each feeding.

Nicotine exposure in breastfed infants

A Dahlström, C Ebersjö, B Lundell

Acta Paediatr. 2004 Jun;93(6):810-6.

Abstract

Aim: To study exposure to nicotine in breastfed infants in relation to parental smoking habits.

Material and Methods: Forty mother-infant pairs were studied. Twenty non-smoking mothers, 18 smoking (2–20 cigarettes per day) and two snuff-taking mothers were included. All infants were healthy, exclusively breastfed and their postnatal age was 6 wk. During a home visit, parental smoking habits were recorded, and the time of mothers’ last smoke or taking of snuff and breastfeeding were recorded. Breast milk and infant urine samples were collected. Concentrations of nicotine and cotinine were analysed with gas chromatography.
