First-trimester smoking cessation in pregnancy did not increase the risk of preeclampsia/eclampsia: A Murmansk County Birth Registry study

摘要

Although prior studies have shown that smoking reduces preeclampsia/eclampsia risk, theconsequence of giving up this habit during pregnancy should be assessed. The aims of thecurrent study were threefold: (i) describe maternal characteristics of women with preeclampsia/eclampsia; (ii) examine a possible association between the number of cigarettes smokeddaily during pregnancy and the development of this affliction; and (iii) determine if first-trimesterdiscontinuation of smoking during pregnancy influences the risk.
