Ban on Cigarette Sales in Public Spaces Reduces Heart Attack Rates in Singapore
The movement to restrict smoking in public spaces has achieved a significant milestone with the banning of cigarette sales in several countries. In 2010, Bhutan became a catalyst for this movement by imposing a ban on cigarette sales. Singapore also stands out for its stringent no-smoking policy in public spaces between 2013 and 2017.
A recent study evaluated the impact of Singapore’s anti-smoking legislation on heart attack rates. Researchers analyzed data from the Singapore Myocardial Infarction Registry between January 2010 and December 2019. The findings reveal the positive effects of Singapore’s smoking restrictions, particularly after their expansion in 2013 to include more public spaces.
Prior to the expansion, the rate of heart attacks was increasing at a monthly rate of 0.9 per million individuals. However, after the expansion, this rate dropped to 0.6 per million. The study suggests that without these legislative measures, an additional 19,591 heart attacks may have occurred in individuals aged 65 and above, with a lower number of 1,325 for those under 65. The elderly demographic and male individuals benefited the most from the broader smoke-free legislation.
These findings are supported by a comprehensive meta-analysis of 18 prior studies conducted across Europe, North America, and New Zealand, which showed an overall 13% reduction in the risk of heart attacks following the implementation of smoke-free legislation.
The study also acknowledged that there was no substantial decline in heart attack cases after the 2017 legislation. However, it emphasized that there was an average reduction in rates across all age groups and genders.
The research utilized data from the Singapore Myocardial Infarction Registry, which is maintained by the National Registry of Diseases Office. The registry tracks specific diseases in Singapore, and notifications of Acute Myocardial Infarction (AMI) cases are legally mandated. The researchers used specific codes to identify AMI cases diagnosed between 2010 and 2019.
To ensure accuracy, the diagnoses were subjected to rigorous central adjudication by physicians based on medical records, clinical presentations, and laboratory test results. Annual audits were conducted to maintain data precision.
The study concludes that the ban on cigarette sales in public spaces has had a significant impact on reducing heart attack rates in Singapore. These findings align with the World Health Organization’s framework for monitoring trends in cardiovascular disease.
While further research is needed to assess the long-term effects of these anti-smoking measures, the study provides valuable insights into the positive outcomes of such legislation.
As the movement to curb cigarette use in public spaces continues to gain momentum, countries around the world can look to Singapore as a successful example of reducing heart attack rates through effective anti-smoking policies.
