In Spain, secondhand smoke (SHS) exposure caused an estimated 1028 deaths in 2011 among never-smokers. Continued efforts are crucial to reduce SHS exposure in unregulated settings and its associated health risks.
Area of Science:
- Public Health
- Epidemiology
- Environmental Health
Background:
- Secondhand smoke (SHS) exposure poses significant health risks, even after smoking bans.
- Assessing SHS-attributable mortality is crucial for public health policy.
- Spain implemented a national smoking law prior to the study period.
Purpose of the Study:
- To quantify deaths in Spain in 2011 attributable to secondhand smoke (SHS) exposure among never-smokers.
- To evaluate the impact of SHS on lung cancer and ischaemic heart disease mortality.
- To inform public health strategies for reducing SHS exposure.
Main Methods:
- Utilized data from a computer-assisted telephone survey of a representative Spanish adult sample.
- Calculated population attributable fractions for lung cancer and ischaemic heart disease based on established relative risks.
- Stratified analyses by sex, age, and exposure setting (home, workplace).
Main Results:
- An estimated 1028 deaths were attributable to SHS exposure at home and work in 2011.
- SHS exposure was linked to 124 lung cancer deaths and 904 ischaemic heart disease deaths.
- Inclusion of ex-smokers or leisure-time exposure significantly increased attributable death estimates.
Conclusions:
- Despite smoking laws, 1028 deaths in Spain in 2011 were linked to SHS exposure.
- Reducing SHS exposure in unregulated settings like homes and cars is essential.
- Further interventions are needed to mitigate SHS-related morbidity and mortality.
