Assessing the Effectiveness of a Community-Based Smoking Cessation Intervention — Shenzhen City, Guangdong Province, China, 2022

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Research on community-based smoking cessation interventions in China is still in its early stages. Most existing studies have focused on a limited number of communities and have primarily examined interventions conducted by study teams rather than broader community initiatives. WHAT IS ADDED BY THIS REPORT? The three-month continuous abstinence rate for the intervention group (21.61%) was significantly higher than that for the control group (8.98%). Comprehensive community-based smoking cessation interventions, administered by trained physicians at community health service centers and supported by community workers, have shown effectiveness in improving a variety of outcomes among community smokers. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The feasibility and effectiveness of comprehensive community-based smoking cessation interventions make them a valuable addition to existing cessation services in China. Wider implementation of these interventions should be pursued as a complementary approach to current efforts to reduce smoking rates in China.
