Children’s Exposure to Environmental Smoke / Involuntary Smoking in Developing Countries: Current Situation and Implications for Health and Development Enis Barış and Ayda A. Yürekli World Bank, Washington, D.C.
Outline • Overview • Health effects • Determinants of ETS • Review of evidence on determinants from developing countries • Estimation of exposure to ETS by level of income and regions • Recommendations
Lack of Access to Clean Air and Child Health • According to WHO, 700 million children around the world were exposed to second hand smoke in 1999. • Lack of clean air is associated with • lower respiratory tract infections • middle ear disease • chronic respiratory symptoms • asthma • decreased lung function • sudden infant death syndrome (SIDS). Source: WHO/TFI: International Consultation on ETS and Child Health, 1999
Determinants of ETS Exposure • The intensity of exposure • The number of smokers • The extent of cigarette consumption • The behavior of smokers • Legislation that restricts smoking in public and work places and its enforcement.
In Developing Countries • Same negative health effects • But of different magnitude • due to variation in the relative importance of exposure determinants, mostly • smoking behavior • legislation • prevailing social norms and ecology, and • as a result of different health and socioeconomic impact in terms of • health consequences (nutrition, co-morbidity) • healthcare costs • absenteeism • societal response (tolerance, compliance, complacency, etc)
Intensity of ExposureNumber of smokers around the globe 2000 Prevalence rate in selected developing countries 1.2 billion smokers globally 83% of global smokers (956 million) live in developing countries
Intensity of ExposureGlobal Cigarette Consumption 2000In 2000, 6.2 Trillion Cigarettes Smoked Worldwide.Developing Countries Smoked 74% of Global Cigarette Consumption (4.6 Trillion Cigarettes) Global cigarette consumption 6260 billion pieces
Intensity of ExposureDaily Smoke Daily 11 to 21 sticks smoked by smokers

Results • 91% of global children aged 0-14 years live in developing world. • 83% of global smokers (956 million) live in developing countries. • In 2000, developing countries smoked 74% of global cigarette consumption (4.6 trillion cigarettes). • Lower number of cigarettes smoked per capita. • Still high rate of ETS exposure at homes and public places: • Over 800 million children are exposed to ETS at homes and 900 million in public places in developing countries. • Most smokers still smoke near non-smokers and/or in front of children.
Conclusion: Worrisome Trends and Patterns • Exposure of children to ETS is larger than previously estimated • Exposure is equally significant in homes and public places, although this varies depending on legislation and social norms • Exposure is likely to become more significant as: • Women take up smoking • Countries develop and economies grow • Exposure is likely to be more hazardous due to other factors, e.g. poverty, other indoor pollutants, nutritional deficiencies, etc.
Conclusion: Policy Implications • Implementation of Framework Convention on Tobacco Control, including legislative initiatives inclusive of ETS; • Higher taxes, especially where price elasticity is higher; and • Involvement of professional associations (teachers, doctors, police force), women’s groups, athletes, etc to mobilize social elites to challenge and change prevailing social norms and enforce existing laws and ordinances. • More comprehensive public health action, bundled with IAP and other initiatives.
Conclusion: Research Implications There is a need to: • Identify culture-specific determinants of ETS amenable to interventions, including risk perception and communication; • Pilot innovative programs involving role models (teachers, mothers, athletes, etc.) and targeting home environments; • Estimate ETS attributable burden of disease and health care costs in developing countries; • Document and cost non-health related effects of ETS, e.g. absenteeism from school, work, etc; and • Seek synergism with other development issues such as IAP due to coal, biomass use, etc.
