Do smoking abstinence periods among pregnant smokers improve birth weight? A secondary analysis of a randomised, controlled trial.

ABSTRACT:

Objectives

Maternal smoking during pregnancy is associated with low birth weight (LBW). Reduction of cigarette consumption does not seem to improve birth weight but it is not known whether implementation of periods of smoking abstinence improves it. We assessed whether the number of 7-day periods of smoking abstinence during pregnancy may help reduce the number of newborns with LBW.

Design and setting

Secondary analysis of a randomised, controlled, multicentre, smoking cessation trial among pregnant smokers.

Participants

Pregnant women were included at <18 weeks of gestational age and assessed at face-to-face, monthly visits. Data of 407 singleton live births were analysed.

Primary outcome measure

Newborns with low birth weight.

Results

40 and 367 newbor
