Abstract

Background In the Philippines, smoking is highly prevalent and tobacco control policies fail to fully implement the WHO Framework Convention on Tobacco Control provisions. To aid in policy change, intervention implementation, monitoring and evaluation, this study aimed to provide the first internally consistent and latest Philippine estimates of the following: disability-adjusted life-years (DALYs) lost due to lung cancer; population-attributable fractions (PAFs) of smoking; and smoking-attributable lung cancer DALYs.

Methods This study applied the Global Burden of Disease and Comparative Risk Assessment frameworks to secondary data, supplemented by expert opinion. A comprehensive internally consistent assessment of disease epidemiology was conducted using DISMOD II and disease impact was quantified as DALYs. PAFs were calculated using the smoking impact ratio and Monte Carlo uncertainty analyses were conducted.

Results For 2008, lung cancer incidence and mortality estimates were 10 871 cases and 9871 deaths respectively. Lung cancer accounted for an estimated 267 787 DALYs lost, 99% of which were due to years of life lost. Overall, the PAF of smoking was 65% and a total of 173 103 DALYs were smoking-attributable. There were increasing trends in incidence, mortality and DALY rates with age. The majority of incidence (72%), mortality (71%) and disease burden (72%) occurred among men, who also had higher PAF estimates.

Conclusions Considerable health gains could be achieved if smoking exposure were reduced in the Philippines. Strong enforcement of measures like increasing taxation to the WHO-endorsed rate, expanding smoke-free environments, and requiring large graphic warnings within a comprehensive tobacco control programme is recommended.
