Survey on Tobacco Use in the GN Sites

Smoking is regarded as one of the few potentially preventable factors associated with low
birth weight, very preterm birth and perinatal death. In an effort to determine the
prevalence of tobacco use (smoking and smokeless tobacco) and to collect relevant data in
support of a potential smoking prevention or cessation intervention, a multi-site tobacco
use survey is being conducted in several countries. The survey will be used to obtain
information on knowledge, attitudes and behaviors among pregnant women in diverse
populations regarding tobacco products.

The primary outcome is tobacco use status during pregnancy. Secondary outcomes include:
knowledge and attitudes regarding tobacco products, health hazards of tobacco use and
environmental tobacco smoke (ETS) exposure.

Sample size of 750 per country was calculated under the assumptions that the prevalence of
tobacco use could be as low as 0.05 with a coefficient of variation of approximately 15% and
a prevalence of 0.10 with a CV of approximately 11%.
