Abstract

Background: The oral health of elderly populations is a significant concern, as it is closely linked to general health and health-related quality of life. Poor oral health exacerbates oral diseases, leading to an increased risk of non-communicable diseases and self-care dependence, particularly in the elderly, worldwide. Knowledge, attitudes, and practices (KAP) play influential roles in individual oral care. However, the evidence of KAP related to oral care among the elderly is still inadequate.

Objective: This study aimed to examine KAP and their associated factors related to oral care among the elderly community.

Methods: A cross-sectional descriptive design was used. The eligible subjects were recruited, using convenience sampling and snowball sampling.

Results: A total of 385 elderly individuals were included, and 51.4% were women. The mean age was 71.66 (SD 6.28). Knowledge was reportedly poor, as more than 50% elderly answered several questions incorrectly. The mean attitude and practices scores were 44.94 (SD 6.33) and 68.90 (SD 10.44), respectively. There was a significant correlation among knowledge, attitudes, and practices (p < 0.001). Multivariable regression analysis revealed numerous factors had remarkably significant association with knowledge [R2 = 0.30, F (4,380) = 11.96, p < 0.001], attitudes [R2 = 0.28, F (6,378) = 9.27, p < 0.001], and practices [R2 = 0.31, F (5,379) = 12.34, p < 0.001], particularly education levels, full-time employment, and self-care independence.

Conclusions: Based on the KAP theoretical model, KAP are closely interrelated. Identified factors associated with KAP are useful to understand at-risk groups. Elderly individuals at lower education levels, with poor family support and inadequate self-care independence, have poor KAP related to oral care. Therefore, this study improves insight for health promotion developers, suggesting that more attention should be paid to at-risk elderly groups' oral health. To enhance participation in dental care and improve oral care performance in the elderly, educational program containing oral health knowledge should be offered to at-risk groups. Family support and involvement are also important for improving oral care among elderly individuals.
