Smoking Cessation Interventions for Chinese American Smokers: A Systematic Review and Meta-Analysis

Background: Smoking cessation interventions are important for decreasing lung cancer mortality rate among Chinese Americans. This study aims to investigate and summarize the intervention methods focusing on smoking cessation among Chinese Americans and to compare the effects of intervention methods on the smoking cessation rates. Methods: A systematic review and meta-analysis design was used in this study. Keyword searching was conducted in August 2021 on PubMed, Google Scholar, PsycINFO, and CINAHL. The methodological quality of each study was assessed using the PEDro scale or The Methodological item for non-randomized studies (MINORS). The Review Manager Version 5.4 software was used to conduct the meta-analysis. Random effect model and subgroup analysis were applied in the analysis. Results: Twenty and 11 studies were included in the systematic review and meta-analysis, respectively. Of the 20 studies, 8 were randomized control studies, 9 were pre-post single group intervention studies, 1 was retrospective analysis for an intervention study, 1 was a baseline data analysis from a cluster randomized trial, 1 was a feasibility intervention study. Results showed that compared to the control group, the group that received interventions on smoking cessation had a significantly increased smoking cessation rate (OR, 3.76; 95% CI, 1.72-8.21; P=0.0009). Subgroup analysis showed individual-based (OR, 5.88) NRT outreach interventions (OR, 3.80) conducted in person (OR, 2.53) with smokers (OR, 6.64) seemed to be more effective to increase smoking cessation rates among Chinese Americans compared with group-based, telephone counseling, indirect remote interventions conducted among Chinese American smokers and their non-smoke family members. Conclusions: Individual-based NRT outreach interventions conducted in person with smokers is an effective way to increase smoking cessation rates among Chinese Americans.
