The 13th World Conference on Tobacco OR Health

Objective: - Characterize levels of SHS in homes with smokers in a number of countries.

- Generate a global profile of SHS exposure among women and children.

- Generate useful data in order to support more progressive smoke-free policies and programs aimed at reducing SHS exposure.

- Identify base-line levels for monitoring the impact of tobacco control policies and programs on voluntary efforts to reduce SHS exposure in homes.

Methods: - Study Design: Cross-sectional exposure survey using area monitors and biological samples.

- Study Population: A convenience sample of 40 homes with a child under 11 years of age was selected in over 30 countries. The precise study population was determined in each country based on past experience, accessibility, and feasibility.

- Secondhand smoke exposure assessment: o Homes: Air nicotine measured in homes using passive sampling. o Biological Samples from Non-smoking Women and Children: Personal exposure to SHS of adult non-smoking women and children under 11 were assessed measuring hair nicotine.

Results: A wide range of exposure to SHS is anticipated across countries and regions. Preliminary results show the highest levels of exposure in homes in Eastern and Southern Europe, often comparable to levels found in bars and restaurants (2.5µg/m3 ). While effective policies have reduced exposure to SHS in workplaces, the results of this study reinforce the need to develop programs and policies to protect women and children from exposure to SHS in their homes.
