Abstract
This article aims to perform an analysis of the factors that determine the self-perception of oral health of Brazilians, based on a multidimensional methodology basis. This is a cross-sectional study with data from a national survey. A household interview was conducted with a sample of 60,202 adults. Self-perception of oral health was considered the outcome variable and sociodemographic characteristics, self-care and oral health condition, use of dental services, general health and work condition as independent variables. The dimensionality reduction test was used and the variables that showed a relationship were submitted to logistic regression. The negative oral health condition was related to difficulty feeding, negative evaluation of the last dental appointment, negative self-perception of general health condition, not flossing, upper dental loss, and reason for the last dental appointment. The use of a multidimensional methodological basis was able to design explanatory models for the self-perception of oral health of Brazilian adults, and these results should be considered in the implementation, evaluation, and qualification of the oral health network.
Highlights
IntroductionThe personal assessment of living and becoming ill is characterized by the interpretation that an individual performs on his/her own health[1,2].Several factors have been pointed out in the literature as capable of influencing this self-assessment: personal characteristics, especially the access to information[3], demographic aspects[4,5,6,7,8,9,10,11,12], level of acculturation[4,6], beliefs, values, health practices[3,6,13], physical and cognitive ability, and emotional relationships[14,15].Due to the subjective nature of the object, classical epidemiological studies are not able to apprehend the elements that are related to the evaluation of the health status of the individuals, since they are mainly devoted to aspects of human biology, clinical, and laboratorial methods. biologically based information is essential for the quantification of the population health conditions, since they subsidize the planning, organization, and monitoring of health services, personal measures are increasingly recommended by the World Health Organization[16]
After the complete database treatment, dimensionality reduction was performed using the Correlation-based Feature Selection (CFS) algorithm using the 10-fold cross validation technique. This data mining test is recommended to be used in a large set of data and variables as proposed in the present study
In the results of the attribute selection analysis, it was verified that the variables most strongly related to self-perception of oral health were: difficulty feeding, upper dental loss, self-perception of the general health condition, evaluation of the last dental appointment, reason for last dental appointment and flossing
Summary
The personal assessment of living and becoming ill is characterized by the interpretation that an individual performs on his/her own health[1,2].Several factors have been pointed out in the literature as capable of influencing this self-assessment: personal characteristics, especially the access to information[3], demographic aspects[4,5,6,7,8,9,10,11,12], level of acculturation[4,6], beliefs, values, health practices[3,6,13], physical and cognitive ability, and emotional relationships[14,15].Due to the subjective nature of the object, classical epidemiological studies are not able to apprehend the elements that are related to the evaluation of the health status of the individuals, since they are mainly devoted to aspects of human biology, clinical, and laboratorial methods. biologically based information is essential for the quantification of the population health conditions, since they subsidize the planning, organization, and monitoring of health services, personal measures are increasingly recommended by the World Health Organization[16]. Due to the subjective nature of the object, classical epidemiological studies are not able to apprehend the elements that are related to the evaluation of the health status of the individuals, since they are mainly devoted to aspects of human biology, clinical, and laboratorial methods. In the oral health field in Brazil, despite the importance of assessing patients’ self-perception on broad and effective bases, most studies have focused on isolated conditions such as clinical (use of dental prosthesis, cavities, and periodontal disease), socioeconomic (income and level of education), socio-demographic (gender, age, and ethnicity), and behavioral factors (consumption of tobacco, alcohol, and other drugs), as well as specific habits of oral hygiene[3,4,5,6,7,8,9,10,11,12,18]
