ABSTRACT
OBJECTIVE@#This study assesses the impact of smoke-free legislation on the incidence rate for acute myocardial infarction (AMI) and stroke in Shenzhen.@*METHODS@#Data on ischemic ( n = 72,945) and hemorrhagic ( n = 18,659) stroke and AMI ( n = 17,431) incidence covering about 12 million people in Shenzhen from 2012 to 2016 were used. Immediate and gradual changes in incidence rates were analyzed using segmented Poisson regression.@*RESULTS@#Following the smoke-free legislation, a 9% (95% CI: 3%-15%) immediate reduction was observed in AMI incidence, especially in men (8%, 95% CI: 1%-14%) and in those aged 65 years and older (17%, 95% CI: 9%-25%). The gradual annual benefits were observed only in hemorrhagic and ischemic stroke incidence, with a 7% (95% CI: 2%-11%) and 6% (95% CI: 4%-8%) decrease per year, respectively. This health effect extended gradually to the 50-64 age group. In addition, neither the immediate nor gradual decrease in stroke and AMI incidence rates did not show statistical significance among the 35-49 age group ( P > 0.05).@*CONCLUSION@#Smoke-free legislation was enforced well in Shenzhen, which would generate good experiences for other cities to enact and enforce smoke-free laws. This study also provided more evidence of the health benefits of smoke-free laws on stroke and AMI.

Background & objectives: The World Health Organization (WHO) document released on the World No Tobacco Day, 2020, mentions that tobacco kills over 22,000 people worldwide every day either from its use or second-hand smoke exposure, which is one person every 4 sec. In 2003, the Cigarettes and Other Tobacco Products Act (COTPA) was enacted by the Indian government to control/regulate use of tobacco and tobacco products. Despite various amendments to this law, there has not been any appreciable decrease in tobacco use. The objective of this study was to assess the compliance level with sections 4-10 of COTPA in urban Puducherry in South India. Methods: Random sample survey of 13 wards was carried out in selected parts of the city of Puducherry. The estimated sample size was minimum 160 public places and point of sales (PoS) each. A pre-tested checklist was used to obtain information on compliance with COTPA. Statistical and spatial analysis was performed using STATA v12.0 and QGIS v2.14.21, respectively. Results: Eight per cent of public places, 0 per cent of PoS, 1.7 per cent of educational institutions and 48 per cent of tobacco packages were found compliant with COTPA specifications. The compliance in public places varied from 0 (bus stops) to 55 per cent (religious places). Interpretation & conclusions: The overall compliance with COTPA was found to be very low in urban Puducherry. In order to ensure proper implementation of the laws, effective enforcement with periodic monitoring of various sections of COTPA are needed.
ABSTRACT
Context: A growing number of cities, districts, counties and states across the globe are going smoke-free. While an Indian national law namely Cigarettes and Other Tobacco Products Act (COTPA) exists since 2003 and aims at protecting all the people in our country; people still smoke in public places. Aim: This study assessed knowledge and perceptions about smoking, SHS and their support for Smoke-free laws among people residing in Mohali district, Punjab. Materials and Methods: This cross-sectional study was conducted in Mohali district of Punjab, India. A sample size of 1600 people was obtained. Probability Proportional to Size technique was used for selecting the number of individuals to be interviewed from each block and also from urban and rural population. Statistical Analysis Used: We estimated proportions and tested for significant differences by residence, smoking status, literacy level and employment level by means of the chi-square statistics. Statistical software SPSS for Windows version 20 was used for analysing data . Results: The overall prevalence of current smoking among study participants was 25%. Around 96% were aware of the fact that smoking is harmful to health, 45% viewed second-hand smoke to be equally harmful as active smoking, 84.2% knew that smoking is prohibited in public places and 88.3% wanted the government to take strict actions to control the menace of public smoking. Multivariate logistic regression analysis showed that people aged 20 years and above, unemployed, urban, literate and non-smokers had significantly better perception towards harms of smoking. The knowledge about smoke free provisions of COTPA was significantly better among males, employed individuals, urban residents, and literate people. Conclusions: There was high knowledge about deleterious multi-dimensional effects of smoking among residents and a high support for implementation of COTPA. Efforts should be taken to make Mohali a "smoke-free district".
