Evaluation of beverage consumption patterns and oral health in Korean adolescents and young adults

Objectives: This study aimed to investigate the beverage consumption patterns and analyze the relationship between the frequency of beverage consumption and oral health in Korean adolescents and young adults who consumed large amounts of sugar from beverages. Methods: Data from the 8th Korea National Health and Nutrition Examination Survey (2019–2021) were analyzed, and 2,787 individuals aged 12-29 years were selected as the study subjects. A complex sample general linear model was used to assess the associations of subject general characteristics and oral health with the frequency of beverage consumption. Results: Both adolescents and young adults frequently consumed carbonated beverages 2.04 and 2.12 times per week, respectively. The most commonly consumed volume per drink was 200 cc. In both groups, the lower the average number of times teeth were brushed daily, the higher was the frequency of fizzy drink consumption. When teeth were brushed less than once daily, the frequency of carbonated drink consumption was 2.63 in adolescents and 2.22 in young adults. Conclusions: This study highlights the need for oral health education of adolescents and young adults on diet and beverage intake. Additionally, information should be provided on oral diseases associated with beverage consumption, such as dental caries and erosion.
