Does knowing about the long-term health effects of alcohol matter? Evidence from a university sample in Lebanon

Abstract

Background: Research linking awareness of health effects of alcohol and harmful alcohol drinking status is limited. Aims: To investigate the association between awareness of long-term alcohol effects and alcohol use disorders. Methods: University students aged 18–25 years (n = 1155) completed a self-filled survey. Participants were asked if they knew that alcohol causes: (1) problems in the liver; (2) cancers of the mouth, throat, oesophagus and breast; (3) damage to the heart; and (4) weakening of the immune system. Multinomial regression analyses were conducted to assess the association between awareness of long-term alcohol effects and alcohol drinking status, including Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) alcohol use disorders. Results: One third (32.8%) were past-year drinkers and 18% screened positive for DSM-5 alcohol use disorders. Compared to past-year drinkers with no alcohol use disorders, non-past-year ever drinkers were twice as likely to know about the link between alcohol and cancers of the mouth, throat, oesophagus and breast. Past-year drinkers with an alcohol use disorders were less likely to know about this association. Non-past-year ever drinkers (vs past-year drinkers with no alcohol use disorders) were also 2.6 times more likely to know the alcohol liver risks. Conclusions: There is a strong inverse relationship between awareness of the effects of alcohol and harmful consumption among young people, providing preliminary support for the protective nature of knowledge on alcohol drinking status. Efforts to increase public awareness of the long-term health effects of alcohol may be useful in reducing alcohol-related harm
