Relationship between stress and subjective oral dryness in the elderly in a rural region: a pilot study

Predicting the Swallow-Related Quality of Life of the Elderly Living in a Local Community Using Support Vector Machine

“…In this study, denture use, aspiration experience in the past one month, being economically inactive, having a mean monthly household income <2 million KRW, being an elementary school graduate or below, female, 75 years old or older, living alone, requiring time for finishing one meal on average ≤15 min or ≥40 min, having depression, stress, and cognitive impairment were predictors associated with the swallowing quality-of-life. A number of studies explored the risk factors of dysphagia and reported that sociodemographic factors (e.g., gender, age, and education level), denture use, and mean required time to finish a meal on average were factors influencing the swallowing quality-of-life [2,6,7], and it supported the results of this study.…”

“…Previous studies have identified old age, gender, cognitive level, stress, number of missing teeth, resilience, and social confidence as factors affecting the swallowing quality-of-life [2,6]. Roy et al [7] reported that “taking a longer time to eat”, “a sensation of food stuck in the throat”, and “coughing, throat clearing, or choking before, during, or after eating” were major risk factors of swallowing disorders.…”

“…However, these studies only identified individual risk factors because (1) they only focused on dysphagia-induced physical problems in patients with the damaged central nervous system such as stroke [9], and (2) they mainly used either a regression model or general linear model to evaluate factors associated with the swallowing quality-of-life [2,6,7,8]. Therefore, it is very meaningful to identify multiple risk factors influencing the swallowing quality-of-life, such as sociodemographic factors, and establishing measures to enhance the swallowing quality-of-life based on the findings.…”
