Summary
Eliminating smoking significantly reduces years lived with disability, extending healthy life expectancy. This indicates that quitting smoking compresses morbidity, leading to a longer, healthier life.
Area of Science:
- Public Health
- Epidemiology
- Gerontology
Background:
- Smoking is a leading cause of preventable morbidity and mortality.
- Understanding the impact of smoking cessation on disability-free life expectancy is crucial for public health interventions.
Purpose of the Study:
- To investigate if eliminating smoking leads to an absolute compression of morbidity.
- To quantify the reduction in years lived with disability by eliminating smoking.
Main Methods:
- Utilized multistate life table calculations.
- Integrated data from the GLOBE study (Netherlands) and the Longitudinal Study of Aging (LSOA, USA).
- Analyzed life expectancy with and without disability at ages 30 and 70.
Main Results:
- A non-smoking population experiences fewer years with disability compared to a mixed smoking-non-smoking population.
- Eliminating smoking at age 30 reduces time with disability by 0.9 years (men) and 1.1 years (women).
- Non-smokers gain 2.5 years (men) and 1.9 years (women) of disability-free life.
Conclusions:
- Eliminating smoking extends life and increases disability-free life years.
- Smoking cessation compresses morbidity, refuting the trade-off between longer life and longer disability periods.
- High priority should be given to interventions aimed at smoking cessation.
