Effects of binge drinking and smoking status on oral healthrelated indicators among Korean adults: a cross-sectional study for 10 years (2013–2022) using Korea National Health and Nutrition Examination Survey data

Objectives: We aimed to determine the impact of binge drinking and smoking on oral health among Korean adults based on their specific habits. Methods: This study used national health and nutrition data from the past 10 years and divided the participants into four groups: Group 1, who never binge drink and quit smoking (No_Sm+Dr); Group 2, who binge drink daily and quit smoking (Drinks); Group 3, who quit drinking and only smoked daily (Smokes); and Group 4, who binge drank and smoked daily (Sm+Dr). Results: Chewing difficulty was more severe in the Drinks (0.195), Smokes (0.340), and Sm+Dr (0.399) groups than in the No_Sm+Dr group. Speech impairment was higher by 0.095 for the Drinks, 0.266 for Smokes, and 0.241 for Sm+Dr groups than for the No_Sm+Dr group, indicating a more serious problem (p<0.05). Conclusions: As oral health problems are most prevalent in individuals who simultaneously engage in binge drinking and smoking than in those who only binge drink or daily smoking, the dental community should prioritize more active and effective guidance on smoking and drinking cessation.
