Interactive Video-Based Passive Drinking and Forced Drinking Education to Reduce Intention to Drink in Adolescents: A Pre-Post Intervention Study

Abstract

Passive and forced drinking harm was prevalent but less recognized in Chinese adolescents. We educated adolescents on such harm to reduce their intention to drink. Students (n = 1244) from seven secondary schools in Hong Kong participated in a video-based health talk on passive and forced drinking harm. Paired t-test was used to assess their change in knowledge of passive and forced drinking, and health and social harm of drinking after, the health talk. McNemar’s chi-squared test and adjusted multivariable logistic regression (AOR) were used to assess their change in intention to drink and intention to quit. Students were less likely to drink (OR 0.29, 95% CI 0.19–0.42) and more likely to quit drinking (OR 3.50, 1.10–14.6) after the health talk. Increased knowledge of passive drinking was associated with less intention to drink (AOR 0.93, 0.90–0.97), increased knowledge of health harm (adjusted b 0.06, 0.05–0.08), and social harm of drinking (adjusted b 0.12, 0.10–0.16). Similar associations were observed in forced drinking (intention to drink: AOR 0.87, 0.79–0.96; health harm: adjusted b 0.16, 0.12–0.19; social harm: adjusted b 0.36, 0.28–0.43). We showed preliminary evidence that the health talk on passive and forced drinking reduced the intention to drink in adolescents.
