The disease burden attributable to smoking in the state of Rio de Janeiro, Brazil in 2000

ABSTRACT

INTRODUCTION: Smoking is one of the main risk factors for morbidity and mortality. An estimated 59 million (4.4 percent) disability-adjusted life years were lost due to smoking throughout the world in 2000. OBJECTIVE: To estimate the disease burden attributable to smoking in the State of Rio de Janeiro, Brazil, for the year 2000. METHODS: Based on estimates of smoking prevalence and relative death risks, the smoking-attributable fraction was calculated for each selected cause, by age and gender. The disease burden attributable to smoking was estimated by multiplying the fractions by the corresponding disability-adjusted life years. RESULTS: In the State of Rio de Janeiro, 7 percent of all disability-adjusted life years were due to smoking. For individuals 30 or more years old, the fraction increased to 10.6 percent (13.6 percent in males and 7.5 percent in females). Chronic obstructive pulmonary disease, ischemic heart disease, cerebrovascular disease, and tracheal, bronchial, and lung cancer accounted for 32.2 percent, 15.7 percent, 13.2 percent, and 11.1 percent of the estimated total DALYs, respectively, amounting to 72.2 percent of the smoking-attributable disease burden. DISCUSSION: Limitations related to parameter estimates were not unique to this study, and therefore should not compromise the comparability of our results. Outcomes were similar to those obtained in other countries, despite methodological differences. CONCLUSION: Smoking is an important risk factor and places a significant disease burden on Rio de Janeiro, Brazil, showing a pattern similar to that observed in high income countries.
