Objective: The aim of this study was to assess and compare knowledge of the health consequences of heavy alcohol consumption among individuals with different substance use statuses.
Methods: We used a cross-sectional study design to analyze the Health Information National Trends Survey (HINTS) 5, Cycle 3 (2019). Participants were classified into four categories based on their substance use status: (a) nonsmoker and nondrinkers; (b) nonsmokers but drinkers; (c) smokers but nondrinkers; and (d) smokers and drinkers. Weighted logistic regression models were utilized to evaluate the association between knowledge of heavy alcohol consumption and health conditions by participants' substance use status.
Results: More than 79% of participants were aware that drinking too much alcohol causes liver disease. However, less than 40% of them realized that heavy alcohol consumption also contributes to cancer. The odds of correctly identifying heavy alcohol consumption as a risk factor for diabetes were 3.00 times (95% confidence interval (CI): 1.29,7.00) higher among smokers but nondrinkers than smokers and alcohol drinkers. Education level was significantly associated with participants' awareness of risk factor (p < 0.01).
Discussion: There is an urgent need for targeted educational campaigns and interventions to increase understanding of the impact of heavy alcohol consumption on cancer risk.
