Area of Science:

• Public Health
• Health Policy
• Adolescent Health

Background:

• Adolescent smoking is linked to long-term health issues like cardiovascular disease.
• Early smoking cessation is crucial for adult health outcomes.
• A 2019 ordinance in Gwangju City, South Korea, aimed to prevent adolescent smoking.

Purpose of the Study:

• To evaluate the impact of the "Ordinance for the Prevention of Child and Adolescent Smoking and Support for Smoking Cessation" on adolescent smoking behaviors.
• To assess changes in environmental conditions related to adolescent smoking post-ordinance.
• To analyze the effectiveness of the ordinance in Gwangju City.

Main Methods:

• Utilized data from the 2018 and 2021 Korea Youth Risk Behavior Survey.
• Employed Propensity Score Matching (PSM) to create comparable groups.
• Applied Difference-in-Differences (DID) analysis to assess changes in smoking behavior and exposure.

Main Results:

• Statistically significant reductions were observed in "experience of secondhand smoke indoors at school".
• A significant decrease was noted in "exposure to smoking advertisements in convenience stores".
• No significant changes were found in other variables, including smoking behavior and cessation advertising.

Conclusions:

• The 2019 Gwangju ordinance positively influenced the school and convenience store environments for adolescent smoking prevention.
• Supplementing the ordinance with management of smoking behaviors and cessation advertising is recommended.
• The policy's primary goal of protecting adolescents from smoking can be further realized with additional measures.
