[[alternative]]青少年族群的二手酒害：危險因子與生活品質影響

[[abstract]]Objectives: The study aimed to investigate the prevalence of alcohol’s harm to others (AHTO), its risk factors, and its relationship with quality of life in adolescents in Taiwan. Methods: Data came from the 2018 National Survey of Substance Use in Taiwan. A total of 3,598 respondents aged 12-17 with national representativeness were included. Sociodemographic characteristics at both family and individual levels, eight forms of AHTO, and five-dimensional quality of life (as assessed by the EQ-5D-5L) were obtained in the survey. Logistic and Tobit regressions with complex survey analyses were used. Results: The lifetime prevalence of AHTO in adolescents was estimated at 0.92%. Parents’ drinking emerged as the strongest risk factor for AHTO experience (adjusted odds ratio [aOR]=14.1). Running away from home and monthly drinking were found to increase the odds of AHTO by 478% and 475%, respectively. Having AHTO experience appeared to be a significant predictor for deteriorated quality of life (adjusted β=-0.17), with that deterioration manifested primarily in the dimension of anxiety/depression. Among all AHTO victims, fewer than one in six ever reached out for help. Conclusions: AHTO provides a vital perspective to help tackle alcohol harm in Taiwan, particularly in the vulnerable underage population. To prevent AHTO-related deterioration in mental health and quality of life among young people in the community, policies and interventions should involve strategies targeting harm to young children in families.
