Aim
To investigate factors that influence the oral health‐related quality of life of older people (65 years and over) in Brazil.
Background
Population‐based studies should be conducted to support health‐planning interventions.
Materials and methods
Data from the São Paulo State Survey on Oral Health (SBSP‐2015), which consisted of 5951 individuals, were used. A theoretical‐conceptual model was built based on the impact of family socio‐economic characteristics, individual social‐demographic features and self‐perceived and clinical oral health status on the oral impact on daily performance (OIDP). Multivariate binary logistic regression analysis was conducted at 5% significance level. Statistically significant variables included within the adjusted logistic regression model entered the multiple correspondence analysis (MCA).
Results
Oral health impact on daily activities was observed in 34.6% of older people. Characteristics significantly related to impact on OIDP score were as follows: family income up to R$ 500 (OR = 2.73), self‐perceived treatment need (OR = 1.33), self‐perceived toothache (OR = 1.52), self‐perception of denture replacement need (OR = 1.27), dissatisfaction (OR = 1.50) or very dissatisfied (OR = 2.57) with own oral health, partial lower denture use (OR = 1.34) and needing partial lower dentures (OR = 1.28). Increased number of people living in the same house (B = 0.05, OR = 1.06), number of bedrooms in the house (B = −0.10, OR = 0.90), age (B = −0.03, OR = 0.97) and number of teeth needing treatment (B = 0.08, OR = 1.08) contributed significantly to OIDP.
Conclusion
Prevalence of OIDP of older people in the state of São Paulo was related to factors other than their clinical and self‐perceived oral health status.
