This study updates the geographic distributions of phlebotomine species in Central-West Brazil and analyses the climatic factors associated with their occurrence. The data were obtained from the entomology services of the state departments of health in Central-West Brazil, scientific collections and a literature review of articles from 1962-2014. Ecological niche models were produced for sandfly species with more than 20 occurrences using the Maxent algorithm and eight climate variables. In all, 2,803 phlebotomine records for 127 species were analysed. Nyssomyia whitmani,Evandromyia lenti and Lutzomyia longipalpiswere the species with the greatest number of records and were present in all the biomes in Central-West Brazil. The models, which were produced for 34 species, indicated that the Cerrado areas in the central and western regions of Central-West Brazil were climatically more suitable to sandflies. The variables with the greatest influence on the models were the temperature in the coldest months and the temperature seasonality. The results show that phlebotomine species in Central-West Brazil have different geographical distribution patterns and that climate conditions in essentially the entire region favour the occurrence of at least one Leishmania vector species, highlighting the need to maintain or intensify vector control and surveillance strategies.

A literatura tem mostrado que piores níveis de saúde bucal estão mais frequentemente relacionados a baixos níveis socioeconômicos, assim este estudo transversal de caráter exploratório investigou a associação entre experiência de cárie e fatores socioeconômicos, acesso a serviços, autopercepção e hábitos em 266 escolares de 12 anos de idade de uma localidade com baixa prevalência de cárie dentária em 2003. Utilizou-se critérios de diagnóstico para cárie dentária da Organização Mundial da Saúde e aplicou-se questionário socioecômico e comportamental. Para a identificação dos fatores associados à experiência de cárie utilizou-se a análise de regressão logística multivariada. A variável dependente foi dicotomizada em CPOD=O e CPOD>0. Considerando as limitações de um estudo transversal, não gostar da aparência dos dentes, procurar atendimento odontológico por dor, estudar em escola pública e o responsável da família ser trabalhador manual foram independentemente associados à experiência de cárie. Mesmo em um município com baixa prevalência de cárie os fatores socioeconômicos, o acesso a serviço odontológico e a autopercepção da saúde bucal foram importantes para a ocorrência da cárie, recomendando-se que diversos fatores sejam investigados dentro do contexto biopsicossocial da sua multifatoriedade.

The literature has shown that poorer levels of oral health are more frequently related to lower socio-economic status, consequently this cross-sectional and exploratory study conducted in 2003 investigated the association between caries and socio-economic factors, access to care, self-perception and habits among 266 12-year-old schoolchildren living in a community with low prevalence of dental caries. World Health Organization dental caries diagnosis methodology was used, in addition to the application of socio-economic and behavioral questionnaires. To identify the factors associated with dental caries, multivariate logistic regression was used and the dependent variable was synthesized into DMFT=0 and DMFT>0. Bearing in mind the limitations of a cross-sectional study, disliking the appearance of teeth, seeking dental care because of pain, studying at a state school and the head of the family being a manual worker were independently associated with dental caries. Even in a municipality with low prevalence of caries, the socio-economic status, dental care and self-perception were important factors in the incidence of dental caries among schoolchildren, and it is recommended that many factors in the bio-psychosocial context of multi-factorial dental caries should be investigated.
