Subjective well-being and oral discomfort in older people

Background: The study aims to assess the relationship between oral discomfort and subjective well-being (SWB) in older people. Methods: A quantitative cross-sectional study was conducted in four Reference Centers for Social Welfare in Fortaleza, Northeastern Brazil. A census was held and individual interviews were carried out with all the older people ( n = 246) enrolled in the centers. A questionnaire addressing sociodemographic data (age, gender, marital status, income, and education) and oral discomfort (dry mouth, difficulty in chewing and swallowing food, problems with the taste of food, burning mouth sensation, pain for no apparent reason, and mouth swelling) and the 62-item SWB scale were used. Results: Participants were 246 people aged 60–89 years (mean of 69 ± 6.9 years). The majority were women ( n = 199; 80.9%), had incomplete primary education ( n = 161; 65.4%), had an income of up to one minimum wage ( n = 182; 74%), were retired ( n = 169; 68.7%), were white ( n = 100; 40.7%), and had no partner ( n = 177; 72%). The mean SWB score (subscale 1) was associated with age (p = 0.010), gender (p = 0.019), health in the previous year (p = 0.027), systemic diseases (p = 0.007), speech problems (p = 0.016), vision problems (p = 0.006), number of teeth (p = 0.010), and dry mouth (p = 0.044). SWB (subscale 2) was associated with gender (p = 0.029), skin color (p = 0.023), general health (p Conclusion: The relationship between oral discomfort and SWB reveals that older people's poor oral health leads to physical, psychological, and/or social problems that directly interfere with their well-being.
