Special Issue Information

Dear Colleagues,

Nutritional status is an important factor in overall health, and malnutrition can significantly elevate the risk of various adverse outcomes and put a greater economic burden on both the individual and society. The promotion of oral health serves as an initial step in preventing these health problems while also lowering the risk of malnutrition. Oral health also plays an important role in the essential human activity of eating, and nutrition is closely associated with oral health status. Nevertheless, the dynamic interaction between oral health and an individual’s overall physical and mental well-being can evolve over the course of one’s life, often in tandem with changes in nutritional status, although their reporting and causal relationships have not been fully explored. In this Special Issue, I hope to gather valuable evidence on various aspects of understanding the link between oral health, nutrition, and health outcomes. I hope that this publication will provide new insights and build upon existing knowledge.

Background: This study aimed to determine whether mental health status contributes to speed eating in adolescents and young adults. Methods: This study enrolled 106 subjects (53 males and 53 females), ranging in age from 12 to 24 years. After a self-administered lifestyle questionnaire and the 12-item General Health Questionnaire (GHQ-12) were administered, a swallowing threshold test was performed. The swallowing threshold was determined based on the concentration of dissolved glucose obtained from the gummy jellies. Low swallowing threshold was characterized by glucose levels falling within the bottom 20th percentile. GHQ-12 was categorized into poor (score 4–12) and normal (score 0–3). Following the univariate analysis, a multivariate binary logistic regression analysis was conducted to determine the factors linked to a low swallowing threshold. Results: Binomial logistic regression analysis revealed that the factors associated with a low swallowing threshold included poor mental health (odds ratio [OR] = 8.47, p = 0.007, confidence interval [CI] = 2.437–32.934) and no physical activity (OR = 5.604, p = 0.008, CI = 1.562–22.675). Conclusions: Speed eating is closely associated with risk behaviors for poor mental health in adolescents and young adults. Full article
