Impact of demographic and clinical variables on the oral health‐related quality of life among five‐year‐old children: a population‐based study using self‐reports

摘要

Background Although SOHO ‐5 has been validated, there is no study testing this instrument in population‐based samples. Aims To evaluate the impact of demographic and oral clinical variables on the oral health‐related quality of life ( OHRQ oL) in 5‐year‐old children from a socially deprived Brazilian area using selfreports. Design Data from 588 children were analyzed. Examinations included untreated dental caries and occlusal deviations. Children answered the Brazilian SOHO ‐5 version and interviewers collected demographic characteristics of the child (sex and skin color). Robust Poisson regression associated outcome and exposures. Results General, the oral impacts were reported by 71.1% of children. The mean and standard deviation total score of the Brazilian SOHO ‐5 were 3.51 and 3.82, respectively. Children with untreated dental caries ( PR = 1.28; P = 0.004) and increased overjet ( PR = 1.35; P = 0.002) experienced a worse OHRQ oL. Dark and mixed skin color children did not have a good impact on their OHRQ oL ( PR = 1.53; P = 0.006 and PR = 1.44; P 0.000, respectively) compared to light ones. Conclusions Untreated dental caries and increased overjet were independently associated with worst OHRQ oL in 5‐year‐old children. As an indication of social deprivation, dark and mixed skin color children compared to light ones presented higher probability for reporting worst OHRQ oL independently of the oral clinical conditions.
