The present study assessed whether number cigarettes smoked per day, as recorded first trimester, influenced outcomes. METHODS Maternal-newborn charts were reviewed for born between 1 January 2003 31 December 2005 to at least one Inuit parent Qikiqtaaluk (Baffin) region Nunavut.

Non-smokers less 5 daily had perinatal equal or better averages birth. Furthermore, average significantly decreased 3681 g non smokers 3310 those 10 day. Compared with non-smokers, (>10 daily) six-fold increase (OR 6.7, 95% CI 2.3-19.6), almost four-fold 3.7, 1.6-8.8) twice chance premature compared non-smokers 2.14, 1.1-4.2). Those most likely other substance use. CONCLUSIONS who not smoking, superior evaluated. reporting increased risk infants. Because use, it is that combination factors this Along public health preventative measures reduce directed high group, contributing adverse need be fully understand complex interactions lead and, therefore, evidence suggests may provide marker poor outcomes, which could direction focused efforts.
