Dor dentaria e fatores associados em adolescentes brasileiros: a Pesquia Nacional de Saude do Escolar (PeNSE), Brasil, 2009

Abstract published in English and Portuguese English title: Dental pain and associated factors in Brazilian adolescents: the National school-based health survey (PeNSE), Brazil, 2009The aim of this study was to assess the prevalence of dental pain and associated socio-demographic and behavioral factors in Brazilian adolescents, using data from the National School-Based Health Survey (PeNSE), Brazil, 2009. The survey was conducted by the Brazilian Institute of Geography and Statistics (IBGE) and Ministry of Health in students 11 to 17 years of age or older in the 27 State capitals, using a self-administered questionnaire. Analyses included Poisson regression following a hierarchical approach. Prevalence of dental pain in the sample (n = 54,985) in the previous six months was 17.8% (95%CI: 17.5-18.1). Higher prevalence was associated with female gender, age 14 years and over, racial self-identification as black, brown, or indigenous, enrollment in public schools, lower maternal schooling, not living with the mother, history of smoking or drinking, less frequent toothbrushing, and heavy consumption of sweets and soft drinks. Dental pain was thus associated with socio-demographic factors and health-related behaviors. = O objetivo deste estudo foi estimar a prevalência da dor de dente em adolescentes brasileiros e analisar fatores sociodemográficos e comportamentais associados, utilizando os dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2009. A pesquisa foi realizada pelo Instituto Brasileiro de Geografia e Estatística e pelo Ministério da Saúde em escolares com idades entre 11 e 17 anos ou mais, das 27 capitais brasileiras, por meio de questionário autoaplicável. Utilizou-se a análise de regressão de Poisson, segundo um modelo hierárquico de determinação. A prevalência de dor na amostra (n = 54.985) nos últimos seis meses foi de 17,8% (IC95%: 17,5-18,1). Prevalências mais elevadas foram encontradas em mulheres, naqueles com 14 anos ou mais, das raças preta, parda e indígena, de escolas públicas, cujas mães tinham baixa escolaridade, que não moravam com a mãe, que haviam experimentado cigarro e álcool alguma vez na vida, que relataram menor frequência de escovação e maior consumo de guloseimas e refrigerantes. A prevalência de dor foi considerável e associada a aspectos sociodemográficos e de comportamentos relacionados à saúde.Maria do Carmo Matias Freire, Cláudio Rodrigues Leles, Luciana Monteiro Vasconcelos Sardinha, Moacir Paludetto Junior, Deborah Carvalho Malta, Marco A.

Assessment of the quality of measures of child oral health-related quality of life

Background Several measures of oral health-related quality of life have been developed for children. The most frequently used are the Child Perceptions Questionnaire (CPQ), the Child Oral Impacts on Daily Performances (C-OIDP) and the Child Oral Health Impact Profile (COHIP). The aim of this study was to assess the methodological quality of the development and testing of these three measures. Methods A systematic search strategy was used to identify eligible studies published up to December 2012, using both MEDLINE and Web of Science. Titles and abstracts were read independently by two investigators and full papers retrieved where the inclusion criteria were met. Data were extracted by two teams of two investigators using a piloted protocol. The data were used to describe the development of the measures and their use against existing criteria. The methodological quality and measurement properties of the measures were assessed using standards proposed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) group. Results The search strategy yielded 653 papers, of which 417 were duplicates. Following analysis of the abstracts, 119 papers met the inclusion criteria. The majority of papers reported cross-sectional studies (n = 117) with three of longitudinal design. Fifteen studies which had used the original version of the measures in their original language were included in the COSMIN analysis. The most frequently used measure was the CPQ. Reliability and construct validity appear to be adequate for all three measures. Children were not fully involved in item generation which may compromise their content validity. Internal consistency was measured using classic test theory with no evidence of modern psychometric techniques being used to test unidimensionality of the measures included in the COSMIN analysis. Conclusion The three measures evaluated appear to be able to discriminate between groups. CPQ has been most widely tested and several versions are available. COHIP employed a rigorous development strategy but has been tested in fewer populations. C-OIDP is shorter and has been used successfully in epidemiological studies. Further testing using modern psychometric techniques such as item response theory is recommended. Future developments should also focus on the development of measures which can evaluate longitudinal change
