OBJETIVO: A obesidade, especialmente de distribuição abdominal, associa-se a fatores de risco cardiovasculares como a dislipidemia, a hipertensão arterial (HA) e o diabetes mellitus (DM). A importância desses fatores em nipo-brasileiros foi previamente demonstrada, apesar de a obesidade não ser característica marcante dos migrantes japoneses. Realizou-se estudo com o objetivo de avaliar a prevalência de excesso de peso e a adiposidade central (AC) em nipo-brasileiros e suas relações com distúrbios metabólicos. MÉTODOS: A amostra incluiu 530 nipo-brasileiros (40-79 anos) de primeira e segunda gerações, submetidos a medidas antropométricas de pressão arterial, perfil lipídico e teste oral de tolerância à glicose. A prevalência (por ponto e intervalo de confiança) de excesso de peso foi calculada pelo valor de corte >26,4 kg/m². O diagnóstico de AC foi baseado na razão entre as circunferências da cintura e do quadril (RCQ), sendo que valores > ou = 0,85 e > ou = 0,95, para mulheres e homens, respectivamente, firmavam esse diagnóstico. RESULTADOS: A prevalência de excesso de peso foi de 22,4% (IC95%-- 20,6-28,1), e a de AC, de 67,0% (IC95% -- 63,1-70,9). Além de maiores prevalências de DM, HA e dislipidemia, estratificando-se pelo índice de massa corporal (IMC) e RCQ, indivíduos com excesso de peso e adiposidade central apresentaram pior perfil metabólico: a pressão arterial foi significantemente maior naqueles com excesso de peso, sem e com AC; indivíduos com AC apresentaram maiores índices de glicemia, triglicerídeos, colesterol total e LDL e menor HDL quando comparados aos sem excesso de peso e sem AC; a insulinemia de jejum foi significantemente maior em indivíduos com excesso de peso (sem e com AC) do que naqueles sem excesso de peso e sem AC. CONCLUSÃO: A comparação de subgrupos com e sem adiposidade central foi compatível com a hipótese de que a deposição abdominal de gordura representa fator de risco para doenças interligadas pela resistência à insulina, inclusive em população de origem oriental. A alta prevalência de síndrome metabólica nos migrantes japoneses pode ser decorrente da deposição visceral de gordura, implicada na gênese da resistência à insulina.OBJECTIVE: Obesity, especially abdominal, has been associated with cardiovascular risk factors such as dyslipidemia, hypertension and diabetes mellitus (DM). The importance of these risk factors among Japanese-Brazilians was previously shown, although obesity is not a typical characteristic of Japanese migrants. In this study the prevalence of weight excess and central adiposity (CA) among Japanese-Brazilians and their association with metabolic disorders was evaluated. METHODS: A sample of 530 1st and 2nd generation Japanese-Brazilians (aged 40--79 years) went through anthropometric and blood pressure measurements, lipid profile and oral glucose tolerance tests. The prevalence rate (point and confidence interval) of overweight was calculated using a cut-off value of >26.4 kg/m². CA diagnosis was based on waist-to-hip circumference ratio (WHR): > or = 0.85 and 0.95 in women and men, respectively. RESULTS: The prevalence of weight excess was 22.4% (CI 95% 20.6--28.1), and CA was 67.0% (95% CI 63.1--70.9). In addition to higher prevalence of DM, hypertension and dyslipidemia, stratifying by BMI and WHR, people with weight excess and CA revealed a poorer metabolic profile: blood pressure levels were significantly higher among those with weight excess with or without CA; CA individuals had higher glucose, triglycerides, total and LDL cholesterol, and lower HDL than those without weight excess or CA; fasting insulinemia was significantly higher among subjects with weight excess (with or without CA) than among those without weight excess or CA. CONCLUSION: Comparing subgroups with and without CA supports the hypothesis that abdominal fat accumulation represents a risk factor for insulin resistance-related diseases, even among Japanese descendants. The increased prevalence of metabolic syndrome among Japanese migrants could be attributed to visceral fat deposition, which has been implicated in the genesis of insulin resistance.

INTRODUÇÃO: As estatísticas de mortalidade, em geral, baseiam-se na análise das causas básicas de óbito. No caso do diabetes, sua importância é sempre subestimada, pois os diabéticos geralmente morrem devido às complicações crônicas da doença, sendo estas que figuram como a causa básica do óbito. Para atenuar esse problema, deveriam ser analisadas todas as causas mencionadas no atestado de óbito. Como contribuição ao problema foi analisada a freqüência das menções do diabetes nas declarações de óbito e as principais causas associadas. METODOLOGIA: Os coeficientes específicos e a mortalidade proporcional por diabetes, como causa básica ou associada, foram calculados com base nas informações extraídas dos atestados de óbito, através do sistema ACME (Automated Classification of Medical Entities), para o Estado de São Paulo, em1992. RESULTADOS E CONCLUSÕES: De um total de 202.141 óbitos, o diabetes foi mencionado em 13.786 (6,8%), sendo a causa básica em 5.305 (2,6%). A proporção foi maior para mulheres do que para homens (10,1 vs 4,6% como causa mencionada e 6,1 vs 2,9% como causa básica). Entre os óbitos com menção de diabetes no atestado, as principais causas básicas foram: diabetes (38,5%), doenças cardiovasculares (37,2%), doenças respiratórias (8,5%) e neoplasias (4,8%). Quando o diabetes foi a causa básica, as principais causas associadas foram: doenças cardiovasculares (42,2%), respiratórias (10,7%) e geniturinárias (10,1%) . Nos casos onde o diabetes figura como causa associada, as principais causas básicas foram as doenças cardiovasculares (60,5%), respiratórias (13,8%) e neoplásicas (7,9%). Apesar das limitações dos dados obtidos dos atestados de óbito, observou-se que o diabetes representa uma importante causa de morte, traduzindo um problema de saúde de grande magnitude. Também, a análise pelas causas múltiplas de morte fornece um perfil da morbidade associada ao diabetes por ocasião do óbito, salientando a importância das doenças cardiovasculares.INTRODUCTION: Analysis of mortality data are usually performed with reference to the underlying cause of death. The importance of diabetes as a cause of death is always underestimated, because diabetics generally die from chronic complications of the disease, these being considered as the underlying cause of the death. To attenuate this problem, mortality data should be analized on the basis of all the causes listed on the death certificate. Frequency of references to diabetes on death certificates and the principal associated causes were evaluated as a contribution to the solution of this problem. METHODOLOGY: Specific death rates and proportional mortality by diabetes, as underlying or associated cause, were calculated on the basis of information derived from death certificates by the ACME program (Automated Classification of Medical Entities), for the State of S. Paulo, in 1992. RESULTS AND CONCLUSIONS: Of a total of 202,141 deaths, diabetes was mentioned in 13,786 (6.8%) and as being the underlying cause in 5,305(2.6%). The proportion was higher for women than men (10.1 vs. 4.6% as mentioned, and 6.1 vs 2.9% as underlying cause). Among deaths with a mention of diabetes on the certificate, the main underlying causes were: diabetes (38.5%), cardiovascular (37.2%) and respiratory (8.5%) diseases, and neoplasias (4.8%). When diabetes was the underlying cause, the main associated causes were: cardiovascular (42.2%), respiratory (10.7%) and genitourinary (10.1%) diseases. When diabetes was an associated cause, the main underlying causes were: cardiovascular (60.5%) and respiratory (13.8%) diseases, and neoplasias (7.9%). In spite of the limitation of the data from death certificates, it is possible to observe the importance of diabetes as cause of death, reflecting its magnitude as a health problem. Also, the analysis by multiple causes of deaths gives an idea of the morbidity profile associated with diabetes at the time of death, showing the importance of the group of cardiovascular diseases.

Foi avaliada a prevalência de cárie na dentição decídua de crianças entre 0 e 6 anos, matriculadas em creches dos Municípios de Bauru e São Paulo, SP (Brasil). O primeiro grupo (Bauru) não recebia cuidados sistematizados de saúde na instituição e o segundo (São Paulo) apresentava uma rotina de cuidados como norma institucional. Foram analisadas as variáveis relativas aos modos de viver desses grupos populacionais e sua associação com a ocorrência de cárie, efetuando um estudo de caso para caracterização de fatores coletivos de risco à cárie. Através de análise de regressão múltipla, verificou-se a influência da idade e freqüência de consultas odontológicas sobre a prevalência de cárie na amostra estudada (pOral health condition in samples of children from zero to six years old, examined in day nurseries for children from Bauru and S. Paulo County (Brazil) by the caries indicator in primary dentition - dmfs, is assessed. The first group did not receive oral health care where any as the second group received the standard oral care provided by the institution. Variables related to way of life and their relationship to the presence of caries were evaluated. Multiple regression analysis showed a statistically significant association of age and frequency of dental visits with the prevalence of dental caries (p

To evaluate the relationship between diabetic status and periodontal conditions in the Japanese-Brazilian population.The sample consisted of 1,315 subjects, of both sexes, first (Issei) and second (Nisei) generations, aged 30 to 92 years, living in Bauru, Brazil. Edentulism and presence of 6 null sextants were the exclusion criteria for the sample. The Community Periodontal Index and Periodontal Attachment Loss Index were determined using the probing of 10 teeth in a sample of 831 subjects. The diagnosis of diabetes mellitus was based on fasting blood sugar and blood sugar 2 hours after 75 mg of glucose overload. Statistical analysis was conducted using Kappa test and Chi-square test.Regarding periodontal conditions, 25.5% of the sample were healthy people, 12.5% showed bleeding on probing, 49.4% calculus, 10.4% pockets of 4-5 mm deep, and 2.2% pockets deeper than 6 mm. The percentage of subjects with an attachment loss of 0-3 mm was 24.2%; 4-5 mm, 36.7%; 6-8 mm, 23.7%; 9-11 mm, 11.3%; and up to 12 mm or more, 4.1%. The association between the periodontal condition and diabetes mellitus showed no statistical significance (p0.05), although diabetic subjects have a higher percentage of deeper pockets and attachment loss6 mm than non-diabetics, as tested by Chi-square test.Epidemiological studies relating oral health and systemic disease, such as diabetes mellitus, can provide important contributions for preventing the worsening of such diseases.

Obesity, especially abdominal, has been associated with cardiovascular risk factors such as dyslipidemia, hypertension and diabetes mellitus (DM). The importance of these risk factors among Japanese-Brazilians was previously shown, although obesity is not a typical characteristic of Japanese migrants. In this study the prevalence of weight excess and central adiposity (CA) among Japanese-Brazilians and their association with metabolic disorders was evaluated.A sample of 530 1st and 2nd generation Japanese-Brazilians (aged 40 - 79 years) went through anthropometric and blood pressure measurements, lipid profile and oral glucose tolerance tests. The prevalence rate (point and confidence interval) of overweight was calculated using a cut-off value of26.4 kg/m2. CA diagnosis was based on waist-to-hip circumference ratio (WHR): greater-than-or-equal 0.85 and 0.95 in women and men, respectively.The prevalence of weight excess was 22.4% (CI 95% 20.6 - 28.1), and CA was 67.0% (95% CI 63.1 - 70.9). In addition to higher prevalence of DM, hypertension and dyslipidemia, stratifying by BMI and WHR, people with weight excess and CA revealed a poorer metabolic profile: blood pressure levels were significantly higher among those with weight excess with or without CA; CA individuals had higher glucose, triglycerides, total and LDL cholesterol, and lower HDL than those without weight excess or CA; fasting insulinemia was significantly higher among subjects with weight excess (with or without CA) than among those without weight excess or CA.Comparing subgroups with and without CA supports the hypothesis that abdominal fat accumulation represents a risk factor for insulin resistance-related diseases, even among Japanese descendants. The increased prevalence of metabolic syndrome among Japanese migrants could be attributed to visceral fat deposition, which has been implicated in the genesis of insulin resistance.

To evaluate the way oral habits and speech problems affect dental occlusion in preschool children.A random sample of 2,139 boys and girls aged 3-5 years old was evaluated. The children were enrolled in private and state institutions in the city of Bauru, São Paulo State, Brazil. The cross-sectional study was developed in two steps: occlusion assessment, and a questionnaire about their social and economic status. The occlusal anatomical-functional characteristics assessment was done according to Angle classification. Additionally, overjet, overbite, crowding, anterior open bite, posterior crossbite, and anterior crossbite were evaluated. A sub-sample of 618 children filled out the questionnaire. The prevalence of malocclusion and some variables of exposure were tested by bivariate analysis.The prevalence of malocclusion was 51.3% for boys and 56.9% for girls. There was no difference related to gender. In regard to age, there was a higher prevalence of malocclusion in the 3 year-old group, which decreased significantly with age (p0.05).Among the environmental factors evaluated, the habit of sucking a pacifier was the most important in the association with malocclusion (OR=5.46) followed by the habit of sucking fingers (OR=1.54). Speech problems did not show any influence in malocclusion occurrence.

As part of a study involving Japanese migrants, living in a developed city in the state of S. Paulo, Southeastern Brazil, a four-year experience of mortality among diabetic and non-diabetic subjects is described and their respective death rates are compared. In 1993, a cohort of 530 Japanese-Brazilians (236 issei or 1st generation and 294 nisei or 2nd generation) of both sexes, aged 40 from to 79 years old, were identified.At that time, 91 (17%) were classified as non-insulin-dependent diabetic subjects (NIDDM), 90 (17%) with impaired glucose tolerance (IGT) and 349 (66%) as normal, according to WHO criteria. In 1996, families were questioned with a view detecting the deaths which had occurred among the subjects previously studied. This information, in addition to that from death certificates was used to record the date and the causes of death. Mortality rates for all causes and for specific causes (circulatory and renal diseases) were obtained for the three groups of subjects, by glucose tolerance status. Proportional hazard regression models were used to compare the mortality rates, adjusted for several covariables (gender, age, generation, hypertension, dyslipidemia, obesity and serum creatinine).Crude mortality rate ratios for all causes and specific causes, for NIDDM, and normal subjects were 2.95 (95% CI: 1.10-7.62) and 4.57 (95% CI: 1.31-16.48), respectively. No difference was observed between the crude mortality rate ratio for IGT and normal subjects. After simultaneous adjustments for the covariates, higher mortality rates for specific causes were observed among NIDDM than in the normal subjects (mortality rates ratio: 3.86; 95% CI: 1.11-13.38). These results in Japanese-Brazilians are consistent with previous reports of increased mortality in other diabetic subjects, thus confirming the adverse effect of this metabolic disturbance on mortality among diabetic subjects.

Oral health condition in samples of children from zero to six years old, examined in day nurseries for children from Bauru and S. Paulo County (Brazil) by the caries indicator in primary dentition-dmfs, is assessed. The first group did not receive oral health care where any as the second group received the standard oral care provided by the institution. Variables related to way of life and their relationship to the presence of caries were evaluated. Multiple regression analysis showed a statistically significant association of age and frequency of dental visits with the prevalence of dental caries (p0.05). The data also showed that 23.3% of the children from Bauru, and 9.3% of those from S. Paulo were free of caries, numbers that are very far from the 50% proposed by WHO for the year 2000. The overall prevalence of dental caries was greater for the Bauru group than for the S. Paulo group; however, statistical significance was only found in the 3-4 age-group (p0.05). Sex differences in the occurrence of dental caries were not statistically significant.
