Objective: To describe epidemiological traits of diabetic patients attended in the public health network, enrolled in the HiperDia System between 2002 and 2006 and estimate the coverage of this System in the municipality. Method: A cross-sectional study, with secondary data on 7.938 diabetic patients who live in Cuiabá/MT. Descriptive statistics for analysis of the data was used. Results: The HiperDia System coverage was of 58.8%. Most individuals presented type 2 diabetes diagnosis. Over 80% of patients were hypertensive. Among those enrolled, the majority was of women, of individuals born in the state, with low schooling and aged ≥40 years old. The main cardiovascular risk factors identified were overweight, sedentary lifestyle, and cardiovascular family history. Myocardial infarction was the most frequently observed complication. Conclusions: Diabetic patients when enrolled in the HiperDia presented signs of advanced disease stage. Socio-demographic and clinical characteristics detected in these patients can lead to proper management and prevention actions of diabetes in primary health care.

Objective: To identify dietary patterns among adolescents and to assess their association with socioeconomic and lifestyle characteristics and nutritional status. Methods: A probabilistic clustered two-stage sample of students between 14 and 19 years old from public and private high schools from Cuiabá, Mato Grosso, Brazil, was investigated (n = 1.139). A selfadministered food frequency questionnaire was used to obtain information on food intake. Nutritional status was classified according to the Body Mass Index (BMI = weight/height 2 ) z-score. Socioeconomic status was inferred by the education level of head of household and by the presence of electrical appliances in the household. Dietary patterns were identified by applying exploratory factor analysis (extraction method: principal component analysis) and their relationship with socioeconomic conditions, lifestyle variables, and nutritional status was estimated by mutually adjusted multilinear regression models. Results: "Western", "traditional" and "mixed" dietary patterns were identified. Studying in the morning hours and reporting the intake of alcoholic beverages were associated with greater adherence to the "Western" pattern. Male low-income students from public schools who have a BMI in the normal range preferred the "traditional" pattern. The "mixed" pattern was adopted by boys from public schools reporting physical activity. Conclusion: Several factors were associated with dietary patterns of adolescents and the Brazilian traditional diet was associated with normal weight.

O incentivo à prática regular da atividade física vem sendo apontado como importante ação na área da saúde pública, o que vem ensejando iniciativas de larga abrangência populacional, na forma de programas e campanhas em prol de estilos de vida ativos. Neste artigo, fazemos reflexões sobre o processo de adesão à prática regular de atividades físicas e sobre as ações costumeiramente adotadas nesse sentido em programas de promoção da atividade física (especialmente Agita São Paulo e Programa de Educação e Saúde através do Exercício Físico e do Esporte). Identificamos que os objetivos, estratégias e avaliações dos programas enfocam o aumento do nível de atividade física da população e a ampliação de seus conhecimentos sobre os benefícios da atividade física. Tendo em vista a complexidade da adesão à prática de atividades físicas, apontamos a necessidade de se ampliar o número de variáveis sobre as quais devem repousar as ações e a avaliação dos programas. A nosso ver, além do quantitativo de pessoas fisicamente ativas, é preciso considerar variáveis como oferta, acessibilidade e qualidade de espaços para traduzir melhor o desempenho das ações adotadas, tornando mais consistentes a elaboração e a avaliação desses programas de promoção da atividade física de larga abrangência populacional.

Aims: The purpose of this study was to determine the susceptibility of Campylobacter jejuni and Campylobacter coli isolates to antimicrobial agents and to investigate the presence of plasmid DNA. Methods and Results: A total of 15 clinical isolates from children faeces, and 29 animal isolates of Campylobacter jejuni (n 22) and Campylobacter coli (n 22) were tested for susceptibility to 9 antimicrobial agents using a disc diffusion method, and screened for the presence of plasmid DNA by agarose gel electrophoresis. Of the 44 isolates, 56á8% were resistant to sulphonamide, 25% to nor¯oxacin, 18á2% to erythromicin, cipro¯oxacin and ampicillin, and 13á6% to tetracycline. All isolates were susceptible to gentamicin, chloramphenicol and cefotaxime. Plasmids were detected in one Camp. jejuni (4á54%) strain isolated from sheep and in six (27á27%) Camp. coli strains isolated from rhesus monkey(3), swine(2), and poultry(1) with sizes ranging from 3á4 to 50 kb. Conclusions: The majority of the human isolates were susceptible to antibiotics commonly used for the treatment of campylobacteriosis. Signi®cance and Impact of the Study: The origin and spread of Campylobacter resistance to antibiotics are discussed, with particular respect to the current situation in Brazil.

OBJETIVO: Avaliar a associação entre marcadores antropométricos de adiposidade corporal (índice de massa corporal e circunferência da cintura) e hipertensão arterial. MÉTODOS: Estudo de corte transversal, de base populacional, realizado no período de 2003 a 2004, com 1.298 indivíduos de 20 a 59 anos. Foram considerados hipertensos os indivíduos com pressão arterial > 140/90 mmHg ou em uso de medicação anti-hipertensiva. As associações entre os indicadores antropométricos e a hipertensão arterial foram analisadas por regressão de Poisson, ajustada por potenciais fatores de confusão (sexo, idade, escolaridade, tabagismo, consumo de bebida alcoólica e atividade física no lazer). A curva ROC foi utilizada para determinar o melhor ponto de corte do IMC para detecção da hipertensão arterial. RESULTADOS: A prevalência de hipertensão arterial foi de 28,3%, sendo 33,5% no sexo masculino e 23,5% no feminino. Após ajuste para o IMC e potenciais fatores de confusão, a circunferência da cintura perdeu associação com o desfecho avaliado, permanecendo apenas o IMC com poder de explicação para a hipertensão arterial (RP = 1,05, p = 0,001). O melhor ponto de corte para o IMC no sexo masculino foi de 25,6 Kg/m², e no sexo feminino 25,7 Kg/m². CONCLUSÕES: A associação observada entre a circunferência da cintura e a hipertensão arterial em muitos estudos pode estar relacionada à ausência de controle de potenciais fatores de confusão nas análises, bem como à não remoção do efeito da adiposidade total. Novas investigações devem ser conduzidas na população brasileira, a fim de se verificar as verdadeiras associações entre indicadores antropométricos e vários desfechos, estudando-se também os melhores pontos de corte desses indicadores.

Self-reported measures have been used to obtain weight and height information in some epidemiological surveys. The validation of such information is necessary to guarantee data quality. This study assessed the validity of self-reported weight and height to determine weight status. Data were obtained in the Brazilian National Health Survey, a Brazilian household-based nationwide survey carried out in 2013. In this survey, 40,366 individuals (aged ≥ 18 years) provided self-reported and measured information about weight and height. Student's paired t-test was used to verify the differences between self-reported and measured data. The agreement between measurements was obtained using the intraclass correlation coefficient (ICC) and Bland-Altman method. To evaluate variations in weight status categorizations, the weighted kappa coefficient and exact agreement were used. Sensitivity and specificity were estimated for the self-reported information to classify overweight and obese individuals. There was high agreement between self-reported and measured weight, height, and body mass index (ICC > 0.88). The mean agreements estimated by the Bland-Altman method were 99.6% for weight and 100.6% for height. The weighted kappa coefficient showed substantial agreement among the weight status categories (> 0.66); the exact agreement was 77%. Sensibility and specificity for overweight (83% and 87.5%, respectively) and obesity (73.4% and 96.7%, respectively) were considered high for the sociodemographic characteristics evaluated. According to our results, self-reported measurements of weight and height can be used cautiously as valid alternatives to determine weight status.
