- ItemAcesso aberto (Open Access)Effect of Continuous and Interval Physical Exercise on Weight and Biochemical Profile of Pregnant Wistar Rats and Consequences on Fetal Body Weight(Soc Brasileira Med Esporte, 2011-11-01) Barbalho, Sandra Maria; Souza, Maricelma da Silva Soares de; Silva, Julio Cesar de Paula e; Coqueiro, Daniel Pereira [UNIFESP]; Oliveira, Gabriela Aparecida de; Costa, Tainara; Oshiiwa, Marie; Univ Marilia; Fac Tecnol Alimentos Marilia; UNESP; Universidade Federal de São Paulo (UNIFESP)Exercise training is known for its benefits to the body and mind. However, little is known about the effects of endurance training intensity on pregnancy. We tested the effects of continuous and intermittent exercises (maternal swimming) on the biochemical profile of pregnant Wistar rats and the effects of these exercises on the fetal body weight. The pregnant females (n=60) were divided in control group (GC), continuous exercise group (GCON) and intermittent exercise group (GIN). GC group rats did not practice exercises. GON group rats practiced continuous swimming for 45 minutes a day (five days a week) carrying a bag with 5% of its body weight. GIN group rats practiced intermittent swimming (15 seconds of swimming and 15 seconds stopped) for 45 minutes a day (five days a week) carrying a bag with 15% of its body weight. These exercises were made from the day one until 20(0) day of pregnancy. At the end of this period, we analyzed the mother's glycemia, cholesterol, HDL-C, LDL-C and triglycerides. We also analyzed fetal body weight. No significant modifications on glycemia and plasma lipids (except for LDL-C) were observed in the tree groups. We observed reduction on the fetal body weight in the pups that had their mothers practicing exercises: fetal body weight in GC > GIN > GON (4,153 +/- 0,649; 3,682 +/- 0,070 and 3,453 +/- 0,052 respectively). These results showed that the continuous and intermittent exercise only performed in pregnancy period decreases fetus body weight.
- ItemAcesso aberto (Open Access)Fatores de risco para o baixo peso ao nascer em gestantes de baixa renda(Pontifícia Universidade Católica de Campinas, 2003-06-01) Franceschini, Sylvia do Carmo Castro [UNIFESP]; Priore, Silvia Eloiza [UNIFESP]; Pequeno, Nila Patrícia Freire [UNIFESP]; Silva, Danielle Goes da [UNIFESP]; Sigulem, Dirce Maria [UNIFESP]; Universidade Federal de Viçosa Departamento de Nutrição e Saúde; Universidade Federal de São Paulo (UNIFESP)This paper assessed 77 pregnant women undergoing the last three months of gestation, in order to analyze their exposure to risk factors for low birth weight. They lived in slums in the region of Vila Mariana, a district in the city of São Paulo, and were followed up by the Projeto Favela, developed by the Federal University of São Paulo/School of Medicine. The maternal variables which most influenced birth weight were the mother's number of pregnancies and height. Primiparous women gave birth to newborns with lower birthweight, presenting an average difference of -264g when compared with infants born to multiparous mothers. Women whose height did not exceed 150cm also delivered infants with lower birth weight, demonstrating an average difference of -287g when compared with neonates born to taller mothers. Only 2.6% of the infants presented low birth weight, despite the high exposure of the studied population to risk factors.
- ItemSomente MetadadadosMacrosomia(Elsevier Sci Ltd, 2017) Araujo Junior, Edward [UNIFESP]; Peixoto, Alberto Borges [UNIFESP]; Zamarian, Ana Cristina Perez [UNIFESP]; Elito Junior, Julio [UNIFESP]; Tonni, GabrieleFetal macrosomia is defined as birth weight >4000 g and is associated with several maternal and fetal complications such as maternal birth canal trauma, shoulder dystocia, and perinatal asphyxia. Early identification of risk factors could allow preventive measures to be taken to avoid adverse perinatal outcomes. Prenatal diagnosis is based on two-dimensional ultrasound formulae, but accuracy is low, particularly at advanced gestation. Three-dimensional ultrasound could be an alternative to soft tissue monitoring, allowing better prediction of birth weight than two-dimensional ultrasound. In this article, we describe the definition, risk factors, diagnosis, prevention, ultrasound monitoring, prenatal care, and delivery in fetal macrosomia cases. (C) 2016 Published by Elsevier Ltd.
- ItemSomente MetadadadosMalnutrition is associated with increased blood pressure in childhood(Karger, 2004-01-01) Sesso, R.; Barreto, G. P.; Neves, J.; Sawaya, A. L.; Universidade Federal de São Paulo (UNIFESP)Background/Aims: Protein-energy malnutrition remains a major public health problem in many countries. Scanty information is available about the effects of malnutrition during childhood on blood pressure ( BP). Methods: in a cross-sectional study we assessed the BP of 172 children older than 2 years living in shantytowns in São Paulo city. Ninety-one children were malnourished (height-forage or weight-for-age Z-score below -1 of the NCHS references); 20 had recovered from malnutrition after an average time of 6.4 years, and 61 were non-malnourished controls. Results: A greater percentage of children in the malnourished and recovered groups had increased systolic or diastolic BP (>95th percentile of the Update of the 2nd Task Force references) after adjusting for age, sex and height, compared to the controls ( 29, 20 and 2%, respectively, p < 0.001). Mean diastolic BP, adjusted for age, sex, race, weight, height and birth weight, was significantly increased in malnourished and recovered children compared to controls (65.2 +/- 0.6, 66.5 +/- 1.5, and 61.8 +/- 0.8 mm Hg, respectively, p < 0.01). Conclusions: BP is increased in malnourished children and in those who recovered from malnutrition after an average period of 6 years. Malnutrition occurring during childhood may represent a risk factor for increased BP later in life. Copyright (C) 2004 S. Karger AG, Basel.
