    In the absence of intervention, the rate of vertical transmission of HIV can range from 15-45%. With the inclusion of antiretroviral drugs during pregnancy and the choice of delivery route this amounts to less than 2%. However ARV use during pregnancy has generated several questions regarding the adverse effects of the gestational and neonatal outcome. This study aims to analyze the risk factors for vertical transmission of HIV-1 seropositive pregnant women living in Rio Grande and the influence of the use of ARVs in pregnancy outcome. Among the 262 pregnant women studied the rate of vertical transmission of HIV was found to be 3.8%. Regarding the VT, there was a lower risk of transmission when antiretroviral drugs were used and prenatal care was conducted at the referral service. However, the use of ART did not influence the outcome of pregnancy. However, initiation of prenatal care after the first trimester had an influence on low birth weight, as well as performance of less than six visits increased the risk of prematurity. Therefore, the risk factors analyzed in this study appear to be related to the realization of inadequate pre-natal and maternal behavior.Na ausência de intervenção, as taxas de transmissão vertical do HIV podem variar de 15-45%. Com a inserção dos antirretrovirais durante a gestação e a escolha da via de parto estas taxas chegam a menos de 2%. No entanto o uso de ARV na gestação tem gerado várias duvidas quanto aos efeitos adversos causados ao desfecho gestacional e ao neonato. Este estudo objetiva analisar os fatores de risco da transmissão vertical do HIV-1 em gestantes soropositivas atendidas na cidade do Rio Grande e a influência do uso do ARV no desfecho gestacional. Entre as 262 gestantes estudadas a taxa de transmissão vertical do HIV encontrada foi de 3,8%. Em relação à TV, foi observado menor risco de transmissão quando esta havia feito uso de antirretrovirais e o pré-natal era realizado no serviço de referência. Entretanto, o uso de ARV não influenciou negativamente o desfecho gestacional. No entanto, o inicio do pré-natal após o primeiro trimestre teve influencia sobre o baixo peso ao nascer, assim como a realização de menos de seis consultas aumentou o risco de prematuridade. Portanto, os fatores de risco analisados neste estudo parecem estar relacionados à realização não adequada do pré-natal e ao comportamento materno

    OBJECTIVE: To analyze factors associated with the practice of physical activity during pregnancy and its relationship to maternal and child health indicators. METHODS: Cross-sectional study carried out with all births that occurred at maternity hospitals in the municipality of Rio Grande (Southern Brazil) during the year of 2007 (N = 2,557). Information was collected through interviews, by means of a pre-coded questionnaire administered to the mothers. The analyzed maternal and child health outcomes were: hospitalization during pregnancy, cesarean delivery, preterm birth (gestational age < 37 weeks), low birth weight (< 2500g), and fetal death. RESULTS: A total of 32.8% of mothers (95%CI 31.0;34.6) reported having practiced physical activity during pregnancy. The factors associated with practice of physical activity during pregnancy, after adjusting for potential confounders, were: maternal age (inverse association), level of schooling (direct association), mother's first pregnancy, having received prenatal care, and having been instructed in physical activity during prenatal care. Women who practiced physical activity during pregnancy were less likely to deliver surgically and to have a stillbirth. There was no association between physical activity and preterm birth, hospitalization, and low birth weight. CONCLUSIONS: Only one third of mothers reported having practiced physical activity during pregnancy. This behavior was more frequent among younger women with higher level of schooling who were advised during prenatal care. Women who practiced physical activity during pregnancy had fewer cesarean sections and lower occurrence of stillbirths.OBJETIVO: Analizar factores asociados con la práctica de actividad física durante la gestación y su relación con indicadores de salud materno-infantil. MÉTODOS: Estudio transversal realizado con todos los nacimientos ocurridos en maternidades en el municipio de Rio Grande, Sur de Brasil, durante el año 2007 (N=2.557). Las informaciones fueron obtenidas por entrevista, por medio de un cuestionario pre-codificado aplicado a las madres. Los desenlaces de salud materno-infantil analizados fueron: hospitalización durante el embarazo, parto por cesárea, prematuridad (edad gestacional menor de 37 semanas), bajo peso al nacer (OBJETIVO: Analisar fatores associados à prática de atividade física durante a gestação e sua relação com indicadores de saúde materno-infantil. MÉTODOS: Estudo transversal realizado com todos os nascimentos ocorridos em maternidades no município de Rio Grande, RS, durante o ano de 2007 (N = 2.557). As informações foram obtidas por entrevista, por meio de um questionário pré-codificado aplicado às mães. Os desfechos de saúde materno-infantil analisados foram: hospitalização durante a gravidez, parto por cesárea, prematuridade (idade gestacional menor de 37 semanas), baixo peso ao nascer (< 2.500 g) e morte fetal. RESULTADOS: Relataram ter praticado atividade física durante a gestação 32,8% (IC95% 31,0;34,6) das mães. Os fatores associados à prática de atividade física na gestação, após ajustes para possíveis confundidores, foram: idade materna (associação inversa), escolaridade (associação direta), ser primigesta, ter feito pré-natal, e ter recebido orientação para a prática de exercícios durante o pré-natal. Mulheres que praticaram atividade física durante a gestação mostraram menor probabilidade de realização de cesariana e de terem filho natimorto. Não houve associação entre atividade física e parto prematuro, hospitalização e baixo peso ao nascer. CONCLUSÕES: Apenas um terço das mães relatou ter praticado atividade física durante a gestação. Esse comportamento foi mais frequente entre mulheres mais jovens, com maior escolaridade e que receberam orientação. Mulheres que praticaram atividade física durante a gestação realizaram menos cesarianas e tiveram menor ocorrência de natimorto

    OBJECTIVE: To assess factors associated with the establishment of permanent vascular access for patients with end-stage renal disease. METHODS: Cross-sectional study conducted in a nationally representative sample of Brazilian end-stage renal disease patients in dialysis and transplant centers during 2007. The sample comprised only patients who received hemodialysis as a primary therapy modality and reported the type of vascular access for their primary hemodialysis treatment (N=2,276). Data were from the TRS Project - "Economic and Epidemiologic Evaluation of Modalities of Renal Replacement Therapy in Brazil". Multiple logistic regression analysis was used to assess factors associated with the establishment of permanent vascular access in these patients. RESULTS: About 30% of the patients studied had an arteriovenous vascular access. The following factors were associated with a lower likelihood of having an arteriovenous vascular access as a primary type of access: time of hemodialysis start since the diagnosis of chronic renal failure < 1 year; shorter dialysis therapy; having no private health insurance; living in the central-western, northeastern and southeastern regions of Brazil; and living in the northern region plus having no private health insurance. In the final model there was found a positive association between the outcome and pre-dialysis care and no were association with socioeconomic and comorbidity variables. CONCLUSIONS: The study results showed that the focus should on pre-dialysis care to increase the establishment of an arteriovenous vascular access before starting hemodialysis in Brazil
