QUANTITATIVE RISK ASSESSMENT INTEGRATED IN THE HIA OF THE ANTI-SMOKING POLICY PROPOSAL IN HUNGARY Balázs Ádám, Ágnes Molnár, Róza Ádány University of Debrecen Faculty of Public Health Department of Preventive Medicine
HEALTH EFFECTS OF ACTIVE AND PASSIVE SMOKING • ACTIVE SMOKING • carcinogenesis • impaired fertility, teratogenesis • irritation, chronic inflammation • atherosclerosis • immunomodulation • peptic ulcer, bile stone, Crohn’s disease • PASSIVE SMOKING • essentially the same • lower concentrations, weaker evidence
ANTI-SMOKING POLICIES • MPOWER policy package, WHO • Monitor tobacco use and prevention policies • Protect people from tobacco smoke • Offer help to quit tobacco use • Warn about the dangers of tobacco • Enforce bans on tobacco advertising, promotion and sponsorship • Raise taxes on tobacco

AGGRAVATION OF THE HUNGARIAN ANTI-SMOKING POLICY • Act No XLII of 1999 on the protection of non-smokers and on certain rules of consumption and trade of tobacco products • full prohibition of smoking in closed public- and workplaces and on public transport vehicles • further restrictions of promotion and trade

OUTCOME ASSESSMENT • Calculation of disease burden related to active and passive smoking for the baseline and the predicted situation after the prohibition takes place. • valid data • valid functions
AVAILABLE DATA SOURCES • Demographic and mortality data • Central Statistical Office • Morbidity data • General Practitioners Morbidity Sentinel Stations Programme • Cancer Registry • Koranyi National Institute for Tuberculosis and Pulmonology • Exposure data • study on the aetiology of chronic liver disease (Univ. of Debrecen, School of Public Health)
APPLIED FUNCTIONS • Association measures • relative risks from the literature • preferably from meta-analyses • sex-specific when available • distinction of active, former and never smokers • Functions • age-specific population attributable risk fractions • WHO Global burden of disease study • standard discount rate (0.03) • standard age weights (=0.04)
HEALTH OUTCOME MEASURES • Measures of disease burden • attributable death • potential years of life lost • years of life lived with disability • disability adjusted life years
TIME CONSIDERATION • Short term effect • active and former smokers included • initially the majority (85%) of reduction in active smoking is attributable to quitting • risk of major diseases get back to normal in 15 years except for lung cancer • Long term effects • only active smokers included
Reduction in the attributable death of active smoking Number of death active+former Disease
Reduction in the attributable death of active smoking Number of death active+former Disease active
Reduction in the disability adjusted life years of active smoking Life years active+former Disease
Reduction in the disability adjusted life years of active smoking Life years active+former Disease active
Reduction in the attributable death of passive smoking Number of death Disease
Reduction in the disability adjusted life years of passive smoking Life years Disease
Discussion • The health impact assessment of the proposal for smoking prohibition in closed public places in Hungary was carried out involving quantitative risk assessment. • Quantitative assessment was integrated into the scheme of HIA in a structured way. • Numerical prediction proved to be feasible and advantageous in the assessment process. • The health gain of the policy for the four main, tobacco smoke exposure related diseases with the highest public health importance was calculated to be over 1560 lives and close to 20500 disability adjusted life years annually in long term.
