Least likely to smoke were young mothers under age 15 and women 35 and older. However, the patterns differ significantly for white, black and Hispanic mothers. Black mothers were less likely to smoke than their white counterparts. Hispanic mothers, with only 8 percent being smokers, had by far the lowest rate. Hispanic women maintained the low rate of smoking across all ages.
Smoking varies greatly by education.
With more education, smoking declines. Again, there are substantial racial differences. White women at the lowest educational level are twice as likely as black women to smoke. The best thing you can do to help your baby is to forego cigarettes. Their infants were 2 to 4 times as likely to be low birth weight.
