Barbato,Paulo Roberto; Peres,Marco Aurélio;
Revista de Saúde Pública , 2009, DOI: 10.1590/S0034-89102009000100003
Abstract: objective: to estimate tooth loss among adolescents and its factors associated. methods: data from 16,833 participants of the brazilian oral health survey 2002-2003 were analyzed. the outcome studied was tooth loss of at least one tooth. independent variables included geographical localization, gender, skin color, per capita income, education gap, dental service utilization and fluoridated water supply at the local level. crude and adjusted prevalence ratios were estimated using poisson regression for each brazilian macroregion and nationwide. results: the prevalence of at least one tooth loss was 38.9% (95% ci 38.2%;39.7%). adolescents living in localities with non-fluoridated water supply were 40% more likely to have tooth loss compared with those living in areas with fluoridated water supply. there was seen a strong association (p<0.01) between non-fluoridated water supply and tooth loss prevalence in the northeast. in other brazilian regions this association was confounded for distal variables, mainly socioeconomic variables, reinforcing regional inequalities. conclusions: high prevalence of tooth loss among brazilian adolescents shows a need for targeted dental actions including prevention at earlier ages, treatment of affected teeth and universal access to fluoridated water.

Abstract: OBJETIVO: Testar associa es entre indicadores de aten o básica em saúde bucal e indicadores municipais socioecon micos e de provis o de servi os odontológicos. MéTODOS: Estudo ecológico realizado nos 293 municípios do Estado de Santa Catarina, no período 2000 a 2003. Foram utilizados indicadores de aten o básica a saúde bucal: (1) Cobertura; (2) Raz o entre procedimentos odontológicos coletivos e a popula o de zero a 14 anos de idade; (3) raz o entre exodontias de dentes permanentes e procedimentos odontológicos individuais na aten o básica. As variáveis investigadas foram: raz o entre o número total de dentistas por mil habitantes, raz o entre o número total de dentistas cadastrados no Sistema único de Saúde por mil habitantes, fluoreta o da água de abastecimento, índice de desenvolvimento infantil, índice de desenvolvimento humano municipal e a popula o do município. Foram realizadas as análises pelos testes de Kruskall-Wallis, qui-quadrado e o teste de Spearman para avaliar a correla o entre as variáveis. RESULTADOS: A cobertura foi de 21,8%, a raz o de procedimentos coletivos na popula o entre zero a 14 anos foi de 0,37 e a propor o de exodontias em rela o ao total de procedimentos odontológicos individuais foi de 11,9%. Menores propor es de exodontias foram associadas às maiores propor es de dentistas no Sistema (p<0,01). Maiores propor es de exodontias foram associadas aos menores índices de desenvolvimento humano municipal (p<0,01). CONCLUS ES: Maiores coberturas foram associadas ao aumento de dentistas no SUS. Municípios com piores condi es socioecon micas foram associados a maiores propor es de exodontias. Políticas de saúde bucal devem priorizar municípios que apresentam piores indicadores socioecon micos.

Health (Health) , 2013, DOI: 10.4236/health.2013.512268
Abstract:

Introduction: There are few population-based studies conducted in Brazil outside the major urban centers, the prevalence of overweight, obesity and associated factors in the up country cities remains not noticed. Particularly, the characteristics of this phenomenon are unknown in the mountain regions of Santa Catarina (state of the southern region), which concentrate the lowest economic and social development of the state, where culture, dietary habits and climate are quite peculiar. Objective: To estimate the prevalence of nutritional status and its association with self-reported diseases in adults of Lages, Santa Catarina. Methods: A cross sectional study including adults was conducted (n = 2022). Demographic information was collected as well as anthropometric measurements, through a number of interviews and physical examinations. The outcome of the study was the body mass index (BMI). The descriptive statistic was performed, as well as simple associations between BMI and the independent variables by sex. Correlations between BMI, abdominal circumference and self-reported diseases for men and women were tested separately. Results: The prevalence of normal weight, overweight and obesity among men was 41%, 39% and 19% respectively. Among women, the prevalence rates were 43%, 31% and 26%. It was observed that the obesity increase is correlated with low levels of education. The greater the BMI the more negative was the self-assessment of health. It was

found a positive correlation between BMI and abdominal circumference, with diabetes mellitus and high blood pressure levels. Conclusions: There was a high prevalence of overweight and obesity in Lages, SC. Strategies involving the various sectors of the community should be considered to reverse this process.

Peres, Marco Aurélio;Traebert, Jefferson;Marcenes, Wagner;
Cadernos de Saúde Pública , 2001, DOI: 10.1590/S0102-311X2001000100016
Abstract: the aim of this study was describe a training and calibration exercise for dental caries and to discuss the use of validity and reliability statistical tests. eight dentists examined seventeen 12 year-old schoolchildren using world health organization (1997) criteria. data analysis included calculation of the dmf-t index, the percent agreement, and the kappa scores on a tooth-by-tooth basis. inter-examiner agreement was tested against a gold standard examiner. scores for measures of agreement calculated on a tooth-by-tooth basis were lower than those calculated for the whole mouth. the training and calibration exercise is a crucial step in cross-sectional epidemiological surveys, and the kappa test calculated on a tooth-by-tooth basis is the appropriate measurement to test agreement between examiners for dental caries.
