Variables associated with the oral impact on daily performance of adults in the state of São Paulo: A population-based study

This study aimed to assess the oral impact on daily performance and its association with sociodemographic characteristics, tooth pain, need for prosthesis, and periodontal disease of adults in the state of São Paulo, Brazil. This was a cross-sectional epidemiological study with secondary data obtained from the Oral Health Conditions Project- 2015 conducted in 163 municipalities in the state of São Paulo with the participation of 17,560 individuals. This study evaluated adults in the age-range between 35-44 years (n = 5,855), selected by means of probabilistic cluster sampling in two stages. The outcome variable was the OIDP (Oral Impacts on Daily Performances), obtained by using this instrument to assess daily activities (eating, speaking, oral hygiene, relaxation, sports practice, smile, study/work, social contact, and sleep). The independent variables were collected and grouped into three blocks: Block 1 (sex, age group, and ethnic group); Block 2 (household income and education); and Block 3 (tooth pain, need for prosthesis, bleeding, calculus, and periodontal pockets). A hierarchical multiple logistic regression analysis was performed considering the complex cluster sampling plan. Each observation was assigned a specific weight, depending on the location, which resulted in weighted frequencies adjusted for the effect of outlining. the female sex (p
