Quantifying lifetime productivity loss attributable to cigarette smoking in Taiwan

Area of Science:

• Public Health
• Health Economics
• Epidemiology

Background:

• Evaluating the economic impact of smoking is crucial for effective tobacco control policy assessment.
• Smoking imposes substantial long-term health and financial burdens on individuals and society.

Purpose of the Study:

• To estimate the lifetime productivity loss attributable to smoking among adults in Taiwan.
• To provide a data-driven framework for understanding the economic consequences of smoking.

Main Methods:

• A longitudinal cohort study analyzed data from the MJ cohort, linking medical, demographic, and national insurance data.
• Survival and earnings functions were estimated using a rolling extrapolation algorithm and inverse probability of treatment weighting to address confounders.
• Lifetime productivity loss was calculated by comparing smoking and non-smoking groups.

Main Results:

• Smokers had lower employment rates and incomes. Smoking reduced life expectancy by 1.37-2.0 years and employment time by 0.70-1.82 years.
• Average lifetime productivity loss was US$45,572 for men and US$61,552 for women.
• Total lifetime productivity loss in Taiwan was estimated at US$80,589 million, or US$4563 million annually, representing 0.6% of GDP.

Conclusions:

• Smoking leads to significant lifetime and annual productivity losses in Taiwan.
• These findings emphasize the economic rationale for implementing robust tobacco control measures.
• Strengthening tobacco control can mitigate the substantial health and financial burden of smoking.
