Verificaram-se valores de circunferencia da cintura elevados em 33% dos funcionarios, com diferenca significativa entre sexos. Observou-se pressao arterial sistolica (PAS) e pressao arterial diastolica (PAD) elevadas em 18% e 11% dos funcionarios, respectivamente, com associacao significativa entre sexos apos ajuste por idade. Diagnosticou-se diabetes mellitus tipo II em 2% da amostra e glicemia alterada em 4%. Apos ajuste por idade, as unicas variaveis associadas a circunferencia da cintura foram a PAS e a PAD. Estes resultados permitiram que atividades preventivas e educacionais fossem desenvolvidas pela empresa, de modo a melhorar a qualidade de vida e a produtividade dos funcionarios.

The possible role of selenium status in adverse pregnancy outcomes.

The present study reviews the possible role of Se status during pregnancy regarding adverse pregnancy outcomes, with emphasis on those related to diminished antioxidant activity and increased oxidative stress. Studies have reported that Se could play an important role in adverse outcomes such as miscarriages, neural tube defects, diaphragmatic hernia, premature birth, low birth weight, pre-eclampsia, glucose intolerance and gestational diabetes. Also, low Se status has been associated with adverse outcomes among HIV-infected pregnant women and their offspring. Nevertheless, the function of Se in the aetiology of pregnancy complications is yet to be elucidated. Available evidence presents the following limitations: most study designs do not allow conclusions about causal relationships; study populations, selection of subjects, research setting, procedures for defining sample size and analytical methods are often poorly described; many studies fail to adjust for important confounding variables. In addition, population studies assessing the relationship between Se intake during pregnancy and health outcomes are scarce. Further research is still needed to clarify the role of Se status in adverse pregnancy outcomes, especially those related to augmented oxidative stress.

Estado de ferro e retinol sérico entre crianças e adolescentes atendidos por equipe da Estratégia de Saúde da Família de Itajaí, Santa Catarina

The objective of this article is to determine prevalence of iron and vitamin A deficiencies among children and adolescents attended by a Family Health Strategy team in Itajaí, Santa Catarina State, and to assess relations between iron status and serum retinol. A nutritional census of the families was carried out. Socioeconomic and demographic data were collected. Hemoglobin concentration, hematocrite, serum iron and retinal were determined. Thirty-one out of the 156 enrolled families participated in the study. Only 39.1% of the children and 62.0% of the adolescents had their blood samples collected. Mean per capita income was 1.68+/-1.00 minimum wages. None of the parents was illiterate and most families (80.6%) owned their homes. All homes had public sewage and water supply, and 87.1% were made of brickwork. Iron deficiency was diagnosed in 16.7% of the children and 19.3% of the adolescents. Only one child had vitamin A deficiency. Significant correlations were found between serum iron and retinol among children, and among adolescents between serum retinol and hemoglobin concentration and hematocrite. We found mild prevalences of iron and vitamin A deficiencies, possibly due to the socioeconomic and demographic characteristics.Este trabalho visa determinar prevalencias de deficiencia de ferro e vitamina A em criancas e adolescentes atendidos por equipe de Saude da Familia de Itajai (SC) e avaliar relacoes entre o estado de ferro e o retinol serico. Realizou-se um censo nutricional das familias cadastradas. Coletaram-se dados socioeconomicos e demograficos. Avaliou-se a concentracao de hemoglobina, hematocrito, ferro e retinol sericos. Participaram do estudo 31 das 156 familias cadastradas. Apenas 39,1% das criancas e 62,0% dos adolescentes coletaram amostras sanguineas. A renda media per capita foi 1,68±1,00 salarios minimos. Nenhum dos pais ou maes era analfabeto. Residiam em domicilio proprio 80,6% das familias. Todos os domicilios apresentavam esgoto e abastecimento de agua por rede publica e 87,1% eram de alvenaria. Diagnosticou-se deficiencia de ferro em 16,7% das criancas e 19,3% dos adolescentes, e deficiencia de vitamina A em apenas uma crianca. Observaram-se correlacoes significativas para o ferro e retinol sericos entre criancas e entre adolescentes para a concentracao de hemoglobina, hematocrito e retinol serico. Encontraram-se prevalencias leves de deficiencia de ferro e vitamina A, possivelmente devido as caracteristicas socioeconomicas e demograficas.

Prevalência de anemia e níveis séricos de hemoglobina em adolescentes segundo estágio de maturidade sexual

Accelerated growth spurt during adolescence leads to increased nutritional requirements, including iron, therefore posing a nutritional risk to adolescents. The present study aimed to assess the prevalence of anemia and hemoglobin serum levels according to the sexual maturation stage in a representative sample comprised of 272 adolescents enrolled in public schools in Balneario Camboriu, SC. Self-assessment of sexual maturation was carried out according to criteria defined by Tanner (1962). Hemoglobin serum levels were measured through the HemoCue® system and the diagnosis of iron deficiency was based on the cut off points proposed by the World Health Organization (2001). Differences were considered significant at the level of p<0.05. We found a prevalence of 31.2% of anemia without significant differences between genders. Hemoglobin serum levels were significantly higher in boys (p=0.044) than in girls. We did not find significant differences between mean hemoglobin levels of girls who had reached menarche and the ones who had not. There was no statistical association between the presence of anemia and sexual maturation stages of adolescents (c2=1.17; p=0.56). An increase in mean hemoglobin serum levels was observed along with sexual maturation in boys, but not in girls. The results of the present study showed a moderate prevalence of anemia, but did not point out any relation between anemia and sexual maturation in the population studied.

Síndrome metabólica e seus componentes em portadores do HIV

OBJECTIVE: To assess the prevalence of metabolic syndrome and its components in HIV infected individuals assisted in a specialized health center in a municipality in the state of Santa Catarina, Brazil. METHODS: Cross-sectional study comprising 249 individuals (130 men and 119 women), aged 18 to 73 years. Metabolic syndrome was defined according to the National Cholesterol Education Program, as recommended by the Brazilian Society of Cardiology. RESULTS: Among the individuals who participated in the study, 20.9% had metabolic syndrome - 18.5% of the men and 23.5% of the women, with no statistical association between genders. Twenty seven percent of the individuals had two components of the syndrome. Components most frequently found were those related to lipid profile (low HDL cholesterol and high triglycerides), followed by elevated waist-circumference, altered blood pressure and altered fasting blood glucose. There was a significant association between gender and elevated waist-circumference. CONCLUSION: The prevalence of metabolic syndrome found in this study possibly reflects the quality of the health services delivered. We highlight the importance of investigating the presence of metabolic syndrome among HIV-infected populations, thus contributing for their survival.

Confiabilidade do questionário Lista de Atividades Físicas em crianças

OBJECTIVE To assess the reliability of the Lista de Atividades Físicas (Brazilian version of the Physical Activity Checklist Interview) in children. METHODS The study is part of a cross-cultural adaptation of the Physical Activity Checklist Interview, conducted with 83 school children aged between seven and ten years, enrolled between the 2nd and 5th grades of primary education in the city of São Paulo, Southeastern Brazil, in 2008. The questionnaire was responded by children through individual interviews. It is comprised of a list of 21 moderate to vigorous physical activities performed on the previous day, it is divided into periods (before, during and after school) and it has a section for interview assessment. This questionnaire enables the quantification of time spent in physical and sedentary activities and the total and weighed metabolic costs. Reliability was assessed by comparing two interviews conducted with a mean interval of three hours. For the interview assessment, data from the first interview and those from an external evaluator were compared. Bland-Altmans proposal, the intraclass correlation coefficient and Lins concordance correlation coefficient were used to assess reliability. RESULTS The intraclass correlation coefficient lower limits for the outcomes analyzed varied from 0.84 to 0.96. Precision and agreement varied between 0.83 and 0.97 and between 0.99 and 1, respectively. The line estimated from the pairs of values obtained in both interviews indicates high data precision. The interview item showing the poorest result was the ability to estimate time (fair in 27.7% of interviews). Interview assessment items showed intraclass correlation coefficients between 0.60 and 0.70, except for level of cooperation (0.46). CONCLUSIONS The Brazilian version of the Physical Activity Checklist Interview shows high reliability to assess physical and sedentary activity on the previous day in children.OBJETIVO: Avaliar a confiabilidade do questionario Lista de Atividades Fisicas em criancas.
