Associação entre o consumo de gorduras saturadas e sobrepeso ou besidade em crianças e adolescentes de Porto Alegre

Estudo de caso-controle conduzido na cidade de Porto Alegre, com o objetivo de avaliar a associação do consumo de gorduras saturadas com sobrepeso e obesidade. Foram incluídas 52 crianças e adolescentes com idades entre seis e 19 anos, sendo 26 eutróficos e 26 com sobrepeso ou obesidade. Todos responderam a um questionário que contemplava história familiar, atividade física e hábitos alimentares. O consumo diário de alimentos ricos em ácidos graxos saturados no grupo de casos e controles foi, em média, de 31,63 mg e 23,18 mg, respectivamente (p<0,05). Quando a ingestão foi avaliada pelo questionário de freqüência alimentar, os casos apresentaram consumo mais freqüente de produtos lácteos e carne de gado. Este estudo demonstrou que fatores relacionados a história familiar de obesidade, hábitos alimentares inadequados e sedentarismo influenciam no desenvolvimento da obesidade desde a infância, e que a intervenção nutricional precoce torna-se necessária para prevenção de fatores de risco associados ao desenvolvimento desta patologia.

Gestação em pacientes com insuficiência renal crônica

A capacidade reprodutiva diminui na presença de insuficiência renal. O grande desafio no acompanhamento de gestantes com doença renal é manter o ambiente intra-uterino favorável ao feto. Um dos prognósticos comuns nessas gestações envolve prematuridade, crescimento restrito e retardo mental. Os objetivos do presente estudo foram avaliar a evolução clínica das pacientes no período gestacional, verificar o nascimento e o desenvolvimento dos fetos e a prevalência de insuficiência renal crônica em gestantes atendidas no Hospital de Clínicas de Porto Alegre – RS (HCPA). Trata-se de um estudo de caso-controle retrospectivo em 10 anos. O grupo de casos é composto de gestantes com insuficiência renal crônica (IRC). O grupo controle foi pareado pela idade materna, idade gestacional e contemporaneidade entre casos e controles. A prevalência de insuficiência renal crônica foi de 6 por 10.000 gestantes. A idade média das gestantes era de 28 anos, sendo a maioria de cor branca. Quarenta por cento apresentaram pré-eclâmpsia e 56% apresentaram hipertensão arterial sistêmica (HAS) como doença básica. A média de hematócrito foi 24%, e de hemoglobina foi 6,7%, o que demonstra que as pacientes apresentaram anemia no período gestacional. A creatinina apresentou valores médios de 4,61 mg/dl. Sessenta e quatro por cento dos casos evoluíram para um método de terapia renal substitutiva. Sobre a evolução dos fetos no grupo de estudo, mantendo uma significância de 5%, observamos maior índice de prematuridade, maior índice de parto cirúrgico tipo cesariana, baixo peso ao nascer, índice de APGAR no primeiro e quinto minuto reduzido quando comparado ao grupo controle. A pressão arterial foi significativamente superior nos casos em relação aos controles.

Uso de plantas medicinais durante a gravidez e risco para malformações congênitas

A utilização de plantas com fins medicinais para o tratamento, cura e prevenção de doenças, é uma das mais antigas formas de prática medicinal da humanidade. Estas plantas são comercializadas apoiadas em propagandas que prometem benefícios seguros, já que se trata de “fonte natural”. Porém, muitas vezes as supostas propriedades terapêuticas anunciadas não possuem validade científica ou por não terem sido investigadas, ou por não terem tido suas ações farmacológicas comprovadas em testes científicos. Por outro lado, existem evidências significativas em experimentos em animais que muitas substâncias de origem vegetal são potencialmente embriotóxicas ou teratogênicas. Dentro deste contexto, realizamos um estudo do tipo caso-controle de base hospitalar e multicêntrico com o propósito de elucidar os potenciais riscos relacionados ao uso de fitoterápicos em geral, antidepressivos e/ou ansiolíticos de origem vegetal e plantas medicinais com suposta atividade abortiva, com o aparecimento de malformações congênitas maiores nos bebês de gestantes expostas. O presente trabalho tem por objetivo estimar a freqüência do uso de plantas medicinais e seus derivados durante a gestação, particularmente as com potencialidades abortivas e as com efeito sobre o Sistema Nervoso Central, descrevendo as principais substâncias utilizadas e as razões de seu uso. Tais freqüências foram comparadas entre 443 mães de bebês portadores de defeitos congênitos maiores e 443 mães de bebês normais. De acordo com os resultados obtidos abservou-se que 156 (17,6%) puérperas relataram usar algum tipo de fitoterápico e que 300 (33,9%) usaram substâncias de origem vegetal exclusivamente para tratar sintomas de depressão e/ou ansiedade. Não houve diferença estatisticamente significativa entre casos e controles no consumo destas substâncias. Porém, 176 (39,7%) mães de bebês malformados e 110 (24,8%) mães de controle utilizaram plantas com potencialidades abortivas (p<0,001). O conjunto destas observações evidenciou que o uso de fitoterápicos e ansiolíticos/antidepressivos de origem vegetal durante a gestação, não parece estar associado ao aparecimento de defeitos congênitos maiores nesta amostra. No entanto, a observação de que as mães de crianças malformadas utilizaram mais chás considerados abortivos ou suspeitos de algum tipo de risco para a gestação, sugere uma associação entre o uso destas substâncias e o desfecho malformação congênita maior na população estudada. Estes resultados devem ser interpretados cuidadosamente, pois podem significar uma ação teratogênica do composto vegetal, ou podem dever-se à co-existência de outros fatores teratogênicos relacionados à tentativa de aborto.

Riscos e benefícios para o feto e recém-nascido de medicamentos utilizados na gestação : misoprostol e antianêmicos

Foi investigada a associação entre a utilização pré-natal de medicamentos com finalidade profilática, terapêutica e não-terapêutica e desfechos adversos da gravidez. Foram analisadas as evidências sobre o potencial teratogênico do misoprostol, por meio de revisão sistemática e metanálise de estudos de caso-controle. A partir da base de dados do Estudo Brasileiro de Diabetes Gestacional (EBDG), uma coorte multicêntrica de gestantes atendidas pelo Sistema Único de Saúde em seis capitais brasileiras, foi analisada a associação entre o uso referido de medicamentos para induzir a menstruação e desfechos adversos perinatais, incluindo anomalias congênitas, morte intra-uterina e nascimento pré-termo. O uso referido e prescrito de sais de ferro, isolado ou associado a vitaminas, foi analisado quanto aos riscos e benefícios da utilização profilática ou terapêutica em relação a nascimento pré-termo e baixo peso ao nascer. Quatro estudos envolvendo 4899 casos de anomalias congênitas e 5742 controles foram incluídos na revisão sistemática de acordo com os critérios de seleção. Nenhum estudo analisou outros efeitos adversos do misoprostol no resultado da gestação. Foi estimado um risco aumentado de anomalia congênita associada ao uso de misoprostol para qualquer defeito congênito (RC= 3,56; IC 95% 0,98 – 12,98), seqüência de Moebius (RC= 25,31; IC 95%11,11 – 57,66) e redução transversa de membros (RC=11,86; IC 95% 4,86 – 28,90). Entre as 4856 gestantes estudadas a partir da base de dados do EBDG, 707 (14,6%) relataram o uso de substâncias para induzir a menstruação, das quais as mais citadas foram chás, hormônios sexuais e misoprostol. Foi verificada associação positiva entre misoprostol e anomalias congênitas ajustado para centro de realização da pesquisa (RC 2,64: IC 95% 1,03 – 6,75). Foi detectada associação positiva entre o uso de hormônios sexuais e anomalias congênitas (RC 2,24; IC 95% 1,06 – 4,74), independente do centro de realização da pesquisa. Para os desfechos morte intra-uterina e nascimento pré-termo, não foi verificada qualquer associação com o uso de misoprostol, hormônios sexuais ou chás. Entre as 3865 gestantes estudadas quanto ao uso de sais de ferro durante a gestação, 805 (20,8%) referiram o uso de sais de ferro isolado e 1136 (29,4%) ferro associado a vitaminas. O uso prescrito de sais de ferro isolado foi verificado para 1973 gestantes (51,0%) e de ferro vi associado a vitaminas prescrito para 890 (23%). A prevalência de anemia foi de 31,3%. Entre as gestantes anêmicas, 70,9% utilizavam sais de ferro e entre as não-anêmicas, o percentual foi de 51,5%. Após ajustamento para potenciais confundidores, o uso prescrito de sais de ferro isolado apresentou associação negativa para nascimento pré-termo em gestantes anêmicas (RC 0,57 IC 95% 0,40 – 0,80) mas não em gestantes não-anêmicas. Para as demais exposições analisadas, não foi verificado qualquer associação. Não foi detectada associação entre o uso de sais de ferro e/ou vitaminas e baixo peso ao nascer. Os resultados apresentados indicam que o uso de misoprostol em gestações que não se perdem está associado a um maior risco de anomalias congênitas, em geral, e de Seqüência de Moebius e redução transversa de membros, em particular. O uso terapêutico de sais de ferro em gestantes anêmicas mostrou associação negativa para nascimento pré-termo. Entretanto, o uso de sais de ferro em gestantes não anêmicas não mostrou relação com os desfechos analisados.

Irregularidade do ciclo menstrual no Menacme como marcador para fatores de risco cardiovasculares na pós-menopausa

A associação entre fatores de risco cardiovascular (FRCV) na pósmenopausa e o antecedente de irregularidade menstrual no menacme foi avaliado em estudo caso-controle envolvendo 414 mulheres na pósmenopausa com idade de 60,4 ± 5,5 anos e IMC de 25,3 ± 4,7 kg/m2. As variáveis consideradas foram: caracterização do ciclo menstrual entre 20 e 35 anos (independente) e relato atual sobre ocorrência de hipertensão arterial, dislipidemia, diabetes mellitus e doença arterial coronariana (dependentes). Utilizou-se o teste qui-quadrado e modelos de regressão logística, ajustados para outras variáveis implicadas no risco para doenças CV, com nível de significância 5%. Observou-se que mulheres que relataram irregularidade menstrual prévia estiveram associadas com risco aumentado para ocorrência de algum FRCV [odds ratio ajustado (OR)= 2,14; IC-95%= 1,02–4,48], quando comparadas àquelas com ciclos regulares. Análise estratificada demonstrou as seguintes associações significativas com o antecedente de irregularidade menstrual: hipertensão arterial (OR= 2,4; 95% IC= 1,39–5,41), hipercolesterolemia (OR= 2,32; 95% IC= 1,17–4,59), hipertrigliceridemia (OR= 2,09; 95% IC= 1,10–4,33) e angioplastia coronariana (OR= 6,82; 95% IC= 1,44–32,18). Os dados sugerem que o antecedente de irregularidade menstrual, indicativo da ocorrência da síndrome dos ovários policísticos na idade reprodutiva, pode estar relacionado com aumento do risco para doenças CV na pós-menopausa __________________________________________________ABSTRACT Menstrual Cycle Irregularity as a Marker of Cardiovascular Risk Factors at Postmenopausal Years.To evaluate the association between cardiovascular risk factors (CVRF)during postmenopausal years and previous menstrual irregularity during reproductive years, we performed a case-control study in 414 postmenopausal women (mean age 60.4 ± 5.5 years; BMI 25.3 ± 4.7 kg/m2). The variables assessed were: menstrual cycle characteristics at age 20–35y (independent) and records of arterial hypertension, dyslipidemia, diabetes mellitus, and coronary heart disease (dependent). Statistical analysis used the chi-square test and logistic regression, adjusting for potential confounders for cardiovascular risk, with significance set at 5%. Women reporting previous menstrual irregularity were associated with increased risk for some CVRF [adjusted odds ratio (OR) 2.14; CI-95%= 1.02–4.48], when compared with those reporting regular menstrual cycles. Stratified analysis demonstrated significant associations of previous menstrual irregularity with: arterial hypertension [OR= 2.74; CI-95%= 1.39–5.41), hypercholesterolemia (OR= 2.32; CI-95%= 1.17–4.59), hypertriglyceridemia (OR= 2.09; CI-95%=1.10–4.33), and coronary angioplasty (OR= 6.82; CI-95%= 1.44–32.18). These data suggest that a prior history of menstrual irregularity, as indicative of polycystic ovary syndrome, may be related to increased risk for CVD during postmenopausal years

Avaliação demográfica, clinico-laboratorial e genética de indivíduos com lupus eritematoso sistêmico e artrite reumatóide residentes em região tropical

The aetiology of autoimmunes disease is multifactorial and involves interactions among environmental, hormonal and genetic factors. Many different genes may contribute to autoimmunes disease susceptibility. The major histocompatibility complex (MHC) genes have been extensively studied, however many non-polymorphic MHC genes have also been reported to contribute to autoimmune diseases susceptibility. The aim of the present study was to evaluate the influence of SLC11A1 gene in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Ninety-six patients with SLE, 37 with RA and 202 controls enrolled in this case-control study, were evaluated with regard to demographic, genetic, laboratorial and clinical data. SLE mainly affects females in the ratio of 18 women for each man, 88,3% of the patients aged from 15 to 45 years old and it occurs with similar frequency in whites and mulattos. The rate of RA between women and men was 11:1, with 77,1% of the cases occurring from 31 to 60 years. The genetic analysis of the point mutation -236 of the SLC11A1 gene by SSCP did not show significant differences between alleles/genotypes in patients with SLE or RA when compared to controls. The most frequent clinical manifestations in patients with SLE were cutaneous (87%) and joint (84.9%). In patients with RA, the most frequent out-joint clinical manifestation were rheumatoid nodules (13,5%). Antinuclear antibodies were present in 100% of the patients with SLE. There was no significant relation between activity of disease and presence of rheumatoid factor in patients with RA, however 55,6% of patients with active disease presented positive rheumatoid factor. Significant association between alleles/genotypes of point mutation -236 and clinical manifestations was not found

Agregação familiar e resultados maternos e perinatais da pré-eclâmpsia severa em população do Rio Grande do Norte

To determine whether there is familiar aggregation of severe preeclampsia in a Brazilian population from Rio Grande do Norte and to characterize the maternal and perinatal outcomes in the studied population. Methods: A case control study was performed with 412 participants who were admitted at Maternidade Escola Januário Cicco (MEJC) for medical care. Of these, 264 subjects presented normal blood pressure and 148 were cases. Cases were composed of eclampsia (n=47), HELLP Syndrome (n=85) and Eclampsia associated with HELLP syndrome (n=16). The diagnosis of these illness were based on the citeria developed by National High Blood Pressure Education Program Working (2000). An interview was performed with each subject and questions related to personal and familiar history of hypertension, preeclampsia, HELLP syndrome and eclampsia. Statistical analysis was performed and comparison of median and mean between cases and controls were performed, with the level of significance of 5%. The Odds-Ratio was determined to estimate the risk of preeclampsia within the families. Results: There were no difference in the demographic data between cases and controls. Previous history of chronic hypertension and preeclampsia was more frequent in the case group. Headaches were more frequent in eclampsia and epigastric pain in the HELLP syndrome cases. Bleeding and oliguria were more frequently found in the eclampsia associated with HELLP syndrome cases. Acute Renal insufficiency was a common complication in the case group, but these cases did not evolve to chronic renal insufficiency. The maternal mortality was 0.4% and the perinatal mortality was high, 223 per 1,000 live births. The 111 risk of a woman to develop preeclampsia whose mother has hypertension or had preeclampsia was respectively 2.5 and 3.5. This risk was increased 5 times, when a sibling has hypertension and 6 times when both sibling and mother had previous history of preeclampsia. Conclusions: This study confirms that there is familiar aggregation of preeclampsia in this Brazilian population. The potential for cardiovascular complications due to development of chronic hypertension indicates the need of closely follow up of women who develop preeclampsia

Periurbanização da leishmaniose visceral e emergência da coinfecção HIV/leishimania, no Rio Grande do Norte

Visceral leishmaniasis (VL) has undergone changes in terms of clinical and epidemiological presentation worldwide. Urbanization has been described in different regions of Brazil and the world, as well as in the state of Rio Grande do Norte. These changes have impacted in the clinical outcome of Leishmania infection. A new clinical entity called co-infection of HIV/Leishmania has been described as a consequence of overlapping areas of occurrence of VL and HIV / AIDS in different countries including Brazil. The aim of this study was to define the process of periurbanization of the LV and describe a case series of co-infection HIV / Leishmania in Rio Grande do Norte. A new demographic pattern of VL was detected, with an increase in the number VL adult male subjects. Analysis of spatial distribution of VL in the state of Rio Grande do Norte showed that in the past 20 years VL tends to occur in larger cities and therefore the highest risk disease is greater in the eastern and western regions. The first region included Natal, the state capital, where the process of suburbanization began in 1990, and more recently the city of Mossoró, the second largest state, where periurbanization began in the last five years. In 1990, the emergence of co-infection HIV/Leishmania in the state was observed. Case-control study revealed that the new clinical entity affects adult males, who acquired HIV through sexual intercourse, 40% of those with a preivous history of leishmania infection Relapse and death from LV is increased in HIV positive compared with HIV-negative patients matched by sex and age. This pattern is similar to the observed in Europe, except of the route of transmission, where in Europe occured concomitantly, by parenteral route in drug users. Analysis of spatial distribution identified overlapping new areas of occurrence of HIV / AIDS and LV potentially signaling to increased risk of this new clinical entity as described above. Therefore, epidemiological surveillance for co-infection HIV / Leishmania should be adopted in all areas of risk of VL. At the same time, it is necessary to evaluate drug resistance currently used in the treatment of VL, as well as parenteral transmission of L infantum/ chagasi in areas where drug dependence is a risk factor for HIV acquisition

Fatores de risco individuais e familiares no desenvolvimento da pré-eclâmpia

Preeclampsia is a spectral disease, with different clinical forms which can evolve with severe multisystemic complications. This present study aimed to determine the risk factors associated with preeclampsia (PE); to validate the existence of aggregation of hypertensive disease in families of women with preeclampsia and verify the existence of association between polymorphisms in the VEGF gene and level of VEGF and its soluble receptor (sFlt1). A case-control study was performed (n = 851). Genotyping of VEGF was performed and serum levels of VEGF and sFlt1 were measured by ELISA. It was observed that 38% of mothers (173, 455) of a case of preeclampsia and 30.8% (78 of 361) of controls had history of hypertension (p <0.0001). Similarly, when examining the history of maternal preeclampsia, we observed that 14.6% (48 of 328) of mothers of women with preeclampsia and 9.6% (12 of 294) of mothers of controls had a history of preeclampsia (p = 0.0001). As for maternal history of preeclampsia, we found that 5.1% (15 of 295) of cases and 3.6% (7 of 314) of controls had a history of preeclampsia (p = 0.0568). Sisters of women with preeclampsia also had a history of hypertensive disease in 9% (41 of 455) versus 6.6% (13 of 361), p = 0.002. Similarly when examining the history of preeclampsia in sisters, it was observed that 22.7% (57 of 251) of a sister of case versus 11.4% (26 of 228) of controls had a history of preeclampsia (P = 0.0011). We observed a decrease in free VEGF in the serum of patients (P <0.05) and increased soluble VEGF receptor. There was no association between polymorphisms in the VEGF gene and preeclampsia. The data obtained in this work validate that hypertensive disease in mothers and sisters with preeclampsia are risk factors for preeclampsia. The risk of illness in the family is higher according to disease severity. High incidence of preeclampsia can be assumed by the high incidence of this disease among the controls. Significant differences between the frequency of preeclampsia in mothers of cases and controls indicate familial factors. Work is being conducted with the to eventually perform genome wide association studies to identify susceptibility loci

Análise das manifestações auditivas em individuos com hipertensão arterial sistêmica

Objective: To determine the prevalence of auditory manifestations in individuals with hypertension and analyze the association between hearing loss, systemic hypertension and quality of life in hypertensive patients. Method: This was a prospective, observational, case-control study, carried out from June 2010 to December 2013 at the University Hospital Onofre Lopes, in Natal, Brazil, which involved 120 patients of both sexes were analyzed with a diagnosis of hypertension and 120 patients without a diagnosis of hypertension. The audiological function was assessed by tonal and vocal audiometry. The quality of life was defines by the MINICHAL BRASIL questionnaire. Results: The prevalence of hearing loss was high in both groups (82.5 % and 75.8 %, in hypertension group and control, respectively, p=0.003). The sensorineural was the most common type of hearing loss (48.5 %) in hypertension group while conductive hearing loss was predominant (61.5 %) in the control group. There were no difference in the intensity of hearing loss between the groups (p=0,21). The main hearing complaint was hearing loss (51 %), followed by ear pain (14 %). There was worse quality of life in hypertensive individuals with hearing loss (p= 0.0001). Conclusion: Hypertensive individuals showed higher prevalence of auditory events, including hearing loss, sensorineural hearing loss is predominant . Hearing loss is associated with worse quality of life of hypertensive individuals even when these pressure values are within normal limits

Estudo dos fatores associados à infecção chagásica em área endêmica do Rio Grande do Norte

The Chagas disease is a infectious and parasite disease that has as the causative agent a Trypanosoma cruzi, a protozoan parasite that can be transmitted to humans by the faeces of triatomines ( barbeiros ) in the blood-sucking. To understand the relationship between factors associated with chagasic infection and the risk of transmission of Trypanosoma cruzi, this work aimed to make a correlation between the results of serology, obtained by different immunological techniques, used for diagnosis of Chagas disease and risk factors to which the population of the city of Apodi-RN is exposed, to be considered a endemic area. The case-control study was conducted with 199 individuals, which initially was applied a questionary about socio-economic questions and some risk factors which they were exposed and also favor the spread of disease. Then was given the diagnosis by immunological techniques of serology by indirect hemagglutination, ELISA and indirect immunofluorescence. From the diagnosis, the subjects were divided into case group (presence of infection) and control group (no infection). Regarding the descriptive characteristics of the sample, were found a higher frequency of female individuals (59.3%), between 36 and 50 years of age (36.7%), with low education level (91%) and income monthly up to 1 minimum wage (67.8%). The serology, performed by three techniques of different principles, had a reactivity of 38.9% by Indirect Hemagglutination, 39.7% by ELISA and 38.7% by Indirect Immunofluorescence. As the result of the serology, 71 of samples showed reactivity in 2 or more techniques. On some risk variables, was found a significant relationship between individuals who had been bitten by the triatomines and had positive serology for Chagas disease (93.3%). Other variables of risk revealed individuals who had positive serology and had domestic animal (80.3%), lived in poorly maintained homes (97.2%) and near the forest (84.5%). A better understanding of the dynamics of transmission of T. cruzi and the risk factors that contribute to its occurrence in a region are needed to develop effective strategies for control of Chagas disease in these áreas

Hipossalivação e seus fatores de risco em idosos funcionalmente independentes e não institucionalizados

The aim of this study was to investigate the risk factors related to hyposalivation among non-institutionalized independently living elderly people, living in Natal-RN, Brazil. The study was a control-case type and the data collection was accomplished by carrying a questionnaire, oral examination and a non-stimulated and stimulated sialometry. The cases were identified by values of salivary flow rate <0,1mL/min and stimulated ≤ 0,5 mL/min, and the controls were by observing the values of sialometry that were bigger than the previously defined parameters. Age and gender were used as pairing variables. The data were analyzed using X2 (α = 0,05) and odds ratio. The sample was composed of 98,1% female and 1,9% male, with mean age 68. There was not association between hyposalivation and the following studied variables: income, schooling, profession, dwelling conditions, domiciliary density, illness, number of teeth and use of prothesis. However, a link was found between hyposalivation and smoking frequency in the passet (OR=5,14), indicating that, referring to elderly people, the tabagism frequency habit was a risk factor to the studied condition. Therefore, refering to non-institutionalized independently elderly people, economic-social-demographic conditions, general and bucal health, diet and habits such as alcoholism have been not risk factors to hyposalivation. However, people that have been smoking have more risk to have the studied conditions

Edentulismo funcional e seus fatores de risco em adultos

The purpose of this study was to investigate the risk factors to the functional edentulism in adults aged 35 a 44 years old of Natal-RN, 278 adults took part in the study. They were all selected from a previous dental loss prevalence study thus being complemented by an active research. The study was a case-control based and data collection was made though a survey as well as with a clinical examination. The cases were identified through individuals with 20 or more teeth. Age and gender were used as variables of pairing off. The data was analyzed through chi-square, significant level of 95% to the checking of its force associations. The independent variables were grouped in three levels. The first one, more macro, is related to the region where the individual lives, which was also related to the second level, the family-based one, linked with a third level, at this low socio-economical level, where the domiciliary density was favorable, living in capital cities, regions with prime sanitary condicitions, with predominant possibility of accessing the public dental service, but in despite of this, only looking for this service when tooth ache is felt, where preferentially an aid dressing treatment is executed in detriment of preventive procedures. From all the samples, less than 25% of the individuals make use of tobacco and alcoholic beverages for quite a number of years. There was an association of functional edentulism with all the studied variables in a regional method. In the family-based with Critério Brasil (OR=4,45) and monthly wages (OR=9,62) and to an to an individual level, the associations took place with the current use of kind of attendance (OR=1,78), looks for dressing treatment (OR=2,51), does not look for preventive treatment (OR=3,31), pain as the main cause of demand (OR=1,92), previous treatment as the demanding reason for dental service (OR+0,28), interval of the last visit to the dental service (OR=1,35) and when advise was received (OR=1,66). It was noticed from the results that the functional edentulism is much more expressive in those families which live in environments with precarious social economical sanitary conditions. Such conditions seem to have a direct influence upon the family social economical conditions which are also shown in detriment to functional edentulism. In the same way, the collection of variants influence the social economical conditions of the individual, as well as the kind of dental service searched by them, the reason of the search and the interval of the last visit to the dental service were strong determiners to the functional edentulism. Beyond that, individual habits like the use of tobacco and its frequency on its previous use influenced in a significant way the existence of functional edentulism in the studied population
