Factors that influence the oral impact on daily performance of older people in Brazil: A cross-sectional population-based study.

Abstract

To investigate factors that influence the oral health-related quality of life of older people (65years and over) in Brazil. Population-based studies should be conducted to support health-planning interventions. 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). 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. 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.
