In 2008/10, the frequency and duration of maternal smoking and other smoking in the household did not have a significant impact on low birth weight.

The rate of high birth weight was much higher (23.9%) for First Nations women living on reserve who never smoked compared to First Nations women living on reserve who smoked throughout their pregnancy (14.3%).

Of those who smoked throughout their pregnancy, those who smoked daily had children with a high birth weight rate of 12.4% compared to 18.1% for those who reported they smoked occasionally.
