Factors influencing oral health-related quality of life (OHRQoL) among the frail elderly residing in the community with their family

The purpose of the present study was to identify factors that influence quality of life (QoL) among frail elderly individuals residing in the community, in order to improve the level of home care related to oral health. Participants were 100 pairs comprising elderly individuals requiring care and their family caregivers. Questionnaire items for the family caregivers related to demographic variables, hours spent caregiving per day, and duration of caregiving. Questionnaire items for the elderly recipients of care concerned demographic variables, activities of daily living (ADL), and cognitive status. According to bivariate analysis, oral health-related quality of life (OHRQoL) was significantly related to basic ADL, communication ADL (CADL), dysphagia risk, and duration of caregiving. From multiple regression analysis, dysphagia risk and CADL were extracted as factors influencing OHRQoL. Assessment of OHRQoL will be useful not only to detect oral health needs but also to evaluate the effect of oral health care in the elderly. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
