Factors Associated with Oral Dryness in Women: An Analysis by Age

Abstract

Aim: Factors associated with oral dryness have not been clarified, although it affects people’s quality of life. Few reports have discussed the relationship between climacteric symptoms and oral dryness. This study aimed to explore factors associated with oral dryness by age.
Methods: We recruited 372 participants. Data were collected using a web-based questionnaire that covered medical history, climacteric symptoms, and dryness of the eyes, nose, mouth, skin and vagina. Data were collected in May 2018. Univariate and multiple logistic regression analyses were performed to examine the relationships between oral dryness and other factors.
Results: The prevalence of oral dryness was 29%–46%. The number of dryness regions was significantly higher in participants with oral dryness in all age groups. Oral and climacteric symptoms were observed in the oral dryness group. The multiple logistic regression analysis showed the number of dryness regions was a significant explanatory variable for oral dryness.
Conclusion: Considering factors associated with oral dryness will support early detection and may contribute to improved quality of life.
