The purpose of this cross-sectional study was to investigate the association between sociodemographic factors, health-related characteristics, functional status and oral health-related quality of life (OHRQoL) among a representative sample of the community-dwelling Lebanese elderly.
The study sample included 905 randomly selected community-dwelling elderly Lebanese aged 65 or older living in Greater Beirut. The sample was selected through multi-stage cluster sampling. Participants completed a comprehensive multi-component questionnaire, administrated by trained interviewers, including sociodemographic factors, health characteristics, eating behaviours and functional characteristics. OHRQoL was assessed through the Geriatric Oral Health Assessment Index (GOHAI) questionnaire.
Among the participants, 51.6% reported poor OHRQoL. The following variables were significantly associated with poor OHRQoL: lack of health insurance (OR = 1.72, 95% CI: 1.05-2.81); poor or average self-rated general health (OR = 2.58, 95% CI: 1.23-5.41 and OR = 2.27, 95% CI: 1.24-4.16, respectively); monotony of diet (OR = 1.69, 95%CI: 1.02-2.79); absence of dentures (OR = 13.78, 95% CI: 5.02-37.84); insufficient dentures (OR = 18.19, 95%CI: 4.43-74.68); presence of dentures (OR = 2.18, 95%CI: 1.16-4.09); and depression (OR = 2.21, 95%CI: 1.26-3.89).
The present study revealed that a lack of health insurance, negative perception of general health, monotony of diet, denture use and depression were significantly correlated with poor OHRQoL among community-dwelling Lebanese elderly.
