Reducing children's exposure to environmental tobacco smoke in homes: issues and strategies.

It is now well established that children's exposure to environmental tobacco smoke (ETS) results in substantial public health and economic impacts. Children are more likely than adults to suffer health effects from ETS exposure, and the home is the most important site of such exposure. Although the responsibility and authority of the community and health professionals to protect children from harm are entrenched in North American society, social, economic, legal, and political factors contribute to a lower level of support for ETS control measures in homes compared with workplaces and public places. It is now clear that ETS control in home environments must be a priority on the public health agenda. Programme and policy options and strategies for ETS control in home environments are outlined. We conclude that the current research base is inadequate to fully support programme and policy development in this area and priorities for research are identified.
