The Effectiveness of Betel Quid Cessation among Workers through the Adoption of the Five Action Areas of the Ottawa Charter.

OBJECTIVE: This study aimed to increase workers' awareness of betel quid cessation. Methods: Using community and workplace resources, a workplace health promotion program was developed in accordance with the five action areas of the Ottawa Charter. Questionnaires were administered to examine the changes in the knowledge and attitudes of 714 workers in different occupations before and three months after the intervention. Results: Regardless of subjects' pre-intervention chewing status, their knowledge and attitude scores relating to betel quid cessation increased significantly after the intervention. The effect of occupation was significant on the post-intervention knowledge and attitude scores among chewers. Furthermore, 16 (11.6%) of the 138 study subjects who chewed betel quid before the intervention and had no willingness to quit, did quit betel quid chewing following the intervention. The factors contributing to an unwillingness to quit among chewers with no intention to quit before the intervention were examined. Workers in the electronic material manufacturing industry had a greater willingness to quit compared to those in the metal, machinery, and related trades (odds ratio [OR] = 0.15; 95% confidence interval [CI] = 0.02-0.94). Travel attendants, tour guides, cleaners, and helpers were the least willing to quit (OR = 21.29; 95% CI = 2.51-180.81). Conclusions: This study promoted workers' awareness of betel quid cessation by adopting the five action areas of the Ottawa Charter framework, the effectiveness of the intervention varied in different occupations. Workers with a high-income and better education level had a higher awareness of betel quid cessation.
