The Associations Between Vaping, Cigarette Smoking and Hazardous Alcohol Use: Findings from a Nationwide Youth Mental Health Study in Singapore
摘要
Electronic cigarettes or vapes are increasing in popularity worldwide. While the association between cigarette smoking and hazardous alcohol use (HAU) is well established, less is known about the relationship between vaping and HAU. This study aims to identify the prevalence rates of and associations between vaping and HAU in Singapore. A total of 2600 youths aged 15 to 35 years were recruited as part of the National Youth Mental Health Study, a cross-sectional epidemiological survey conducted from October 2022 to June 2023. Sociodemographic information and data on vaping as well as smoking were used in the current analysis. A cut-off score of 8 on the Alcohol Use Disorders Identification Test determined HAU case-ness. Of the sample, 18.3% had ever vaped. The most frequently endorsed reasons for initiating vape-use were to start something new (54.6%), enjoy the flavour (42.8%) and quit smoking (32.0%). Vaping was associated with younger age, higher income and having ever smoked. 7.2% met HAU criteria. The combination of smoking and having ever vaped was associated with higher odds of HAU. Despite the e-cigarettes ban in Singapore, more than one in six youths have ever vaped. The occurrence of vaping and smoking was linked to elevated HAU risk. Therefore, there is a need to strengthen deterrence against vaping and smoking among youths as well as to identify polysubstance users for intervention to mitigate subsequent health risk behaviours.
