Smoking Ban: A Long-term Analysis of the Malta Paradox in a Population of over 400,000 Subjects

Abstract

Objectives: The introduction of laws that make indoor public areas and workplaces smoke-free has resulted in a significant<br />reduction in the incidence of acute coronary syndromes (ACS). Malta was the second European country to introduce the<br />smoking ban legislation in April 2004. The purpose of the study was to investigate the impact of the smoking ban in Malta on<br />ACS morbidity and mortality.<br />Methods: The number of ACS hospital admissions and the number of cardiovascular deaths were retrospectively analysed.<br />The annual data for 5 years prior to and following the introduction of the Tobacco Act were obtained according to age-groups<br />for both genders. Poisson regression analyses were performed to assess for decline in ACS admission and cardiovascular<br />death.<br />Results: The ACS admission rate increased throughout the 5 years following the introduction of the smoking ban. There was<br />no change in mortality rate in the 5 years following the legislation, except in 2007 when a small but significant decline was<br />noted.<br />Conclusions: The Malta smoking ban did not have a significant impact on cardiovascular mortality and ACS admissions<br />rates, indicating the need for proper enforcement of the public smoking ban and increase in public awareness regarding the<br />adverse effects of smoking.<br />Key words: Coronary heart disease; Mortality; Prevention; Smoking.
