Exercício de intensidade moderada durante a gravidez é seguro para o feto? Ensaio clínico aberto

To determine the effect of treadmill walking on maternal heart rate (MHR) and cardiotocographic parameters (basal fetal heart rate [FHR], active fetal movements [AFM], number of accelerations and decelerations, and short-term variation [STV] and long-term variation [LTV] of fetal heart rate) in pregnant women at 36 weeks. Methods A nonrandomized, open clinical trial involving 88 healthy pregnant women submitted to moderate intensity walking and computed cardiotocography in 3 20-minute periods (resting, treadmill walking, and postexercise recovery). Results The mean FHR decreased during walking (resting: 137 bpm; treadmill: 98 bpm; recovery: 140 bpm; p <0.001), with bradycardia occurring in 56% of the fetuses in the first 10minutes of exercise, and in 47% after 20minutes. Bradycardia was not detected in the other phases. The mean STV and HV were 7.9, 17.0, and 8.0 milliseconds ( p <0.001) and 7.6, 10.8 and 7.6 bpm ( p =0.002) in the resting, walking and recovery phases, respectively. The mean number of fetal movements in 1 hour was 29.9, 22.2 and 45.5, respectively, in the 3 periods ( p <0.001). In overweight/obese women, the mean FHR was lower ( p =0.02). Following the logistic regression analysis, two variables remained significantly associated with bradycardia: maternal fitness in the 28 (th) week of pregnancy (protective effect) and maternal weight (increased risk). Conclusion In healthy fetuses, physical exercise proved to be safe, since, although FHR and AFM decreased during treadmill walking, an increase in SVT and LTV was observed419531538CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE APOIO À PESQUISA DO ESTADO DA PARAÍBA - FAPESQUniversal 480761/2008-6PPSUS2009Determinar o efeito da caminhada em esteira sobre a frequencia cardiaca materna (FCM) e parametros cardiotocograficos (batimentos cardiofetais basais [BCFs], movimentos ativos fetais [MAFs], numero de aceleracoes e desaceleracoes e variabilidade de curta [STV] e longa [LTV] duracAo da frequencia cardiaca fetal) em gestantes na 36 (a) semana. Metodos Foi realizado um ensaio clinico nAo randomizado e aberto com 88 gestantes saudaveis submetidas a caminhada de moderada intensidade na esteira e a cardiotocografia computadoriza em 3 momentos de 20 minutos (antes, durante e apos a caminhada). Resultados A media dos BCFs diminuiu durante a caminhada, retornando a niveis previos (antes: 137 bpm; durante: 98 bpm; apos: 140 bpm; p <0,001), com bradicardia ocorrendo em 56% dos fetos nos primeiros 10 minutos do exercicio, e em 47% apos 20 minutos. A bradicardia fetal nAo foi observada em outros momentos (antes ou depois). As medias da STV e da LTV foram 7,9, 17,0 e 8,0 milissegundos ( p <0,001) e 7,6, 10,7 e 7,6 bpm ( p =0,002) antes, durante e apos a caminhada, respectivamente. A media dos numeros dos MAFs em 1 hora foi 29,9, 22,2 e 45,5, respectivamente, nos tres momentos ( p <0,001). Nas mulheres com sobrepeso/obesidade, a media da FCM foi menor ( p =0,02). Apos a analise de regressAo logistica, duas variaveis permaneceram significativamente associadas a bradicardia: aptidAo maternal na 28 (a) semana de gravidez (efeito protetor) e peso materno (aumento do risco). ConclusAo Em fetos saudaveis, o exercicio fisico mostrou-se seguro, uma vez que, embora os BCFs e os MAFs diminuam durante a caminhada na esteira, foi observado um aumento da SVT e da LT

Quality of Life of Mothers of Brazilian Children with Congenital Zika Virus Syndrome and Associated Factors

Objective: To evaluate the quality of life of mothers of Brazilian children with congenital Zika virus syndrome (CZS) and associated factors. Material and Methods: This cross-sectional study assessed the quality of life (QoL) of 65 mothers of children diagnosed with CZS using the WHOQOL-bref questionnaire. Information related to mothers and children's characteristics and aspects of QoL (physical, psychological, social and environment domains) was collected. Data were presented using descriptive and inferential statistics. Associations between independent variables and quality of life outcome were carried out through bivariate analyses, adopting a 5% significance level. Results: The “physical” domain showed the highest score (65.98 ± 17.62), while the “environment” domain showed the lowest score (48.55 ± 14.75). The quality of life for the physical domain was associated with maternal schooling and child's sex, while the psychological domain was associated with family income and child's sucking difficulty. Conclusion: Socioeconomic characteristics and comorbidities were associated with mothers' QoL. Knowledge of QoL determinants and their impact on different dimensions of life can serve as a guide for interventions aimed at improving the QoL of this population

Physical activity patterns in pregnant women attending the family health program of Campina Grande - PB

INTRODUÇÃO: A atividade física realizada durante a gestação vem sendo discutida devido aos seus efeitos benéficos tanto para a saúde materna como para o crescimento fetal e desfechos gestacionais, porém ainda são escassos estudos sobre o padrão de atividade física neste período. OBJETIVO: Avaliar o padrão de atividade física entre gestantes atendidas pela estratégia Saúde da Família (ESF) do município de Campina Grande/PB. MÉTODOS:Foi acompanhada uma coorte observacional de gestantes (n=118), a partir da 16ª semana gestacional, durante os anos de 2005 a 2006. A cada quatro semanas eram aferidas as condições clínicas, socioeconômicas e obstétricas, incluindo a aplicação de um questionário específico sobre atividade física na 16ª, 24ª e 32ª semanas gestacionais. A avaliação foi feita a partir da somatória do equivalente metabólico (METs) e as atividades cotidianas foram divididas em quatro grupos: atividades laboral, doméstica e caminhada, além de inatividade. As gestantes foram classificadas de acordo com o padrão de atividade física realizado em: sedentárias, praticantes de atividades física leve, moderada e vigorosa. Os dados foram analisados no programa Epi Info 3.4.1. RESULTADOS: As características socioeconômicas da coorte estudada indicaram majoritariamente gestantes de baixo poder aquisitivo, baixa escolaridade e baixo percentual de mulheres economicamente ativas. O padrão de atividade física observado foi baixo desde o primeiro trimestre gestacional, oscilando entre o leve e o sedentário, e foi diminuindo com o evoluir da gravidez, com 100% das gestantes alcançando o padrão sedentário na 32ª semana. Em relação aos grupos de atividades, observou-se um predomínio de atividades domésticas, seguidas pelas atividades de lazer. CONCLUSÃO:Na coorte estudada verificou-se um padrão de atividade física inadequado desde o início da gestação, agravando-se no terceiro trimestre gestacional.INTRODUCTION: The benefits of physical activity during pregnancy on fetal growth, maternal health and pregnancy outcomes have been debated; however, studies on the physical activity patterns during this period are still scarce. OBJECTIVE: To evaluate the physical activity patterns of pregnant women attending the Family Health Strategy at the municipality of Campina Grande, PB. METHODS:A cohort of 118 pregnant women was followed from 2005 to 2006. Follow up started on the 16th gestational week and continued at every four weeks to assess clinical conditions and collect obstetric and socio-economic information. A specific questionnaire on physical activity was applied on the 16th, 24th and 32nd gestational weeks, which was estimated through the weekly sum of the metabolic equivalent (MET). Daily activities were classified in four groups: labor, household, walking, and inactivity. According to the physical activity pattern, women were classified as sedentary, or performing light, moderate or vigorous activity. The data set was analyzed in Epi Info 3.4.1 RESULTS: The socioeconomic characteristics of the cohort described a population of low levels of income and education. The physical activity pattern observed since the first gestational trimester was low, ranging from light to sedentary and it decreased along pregnancy. On the 32nd gestational week 100% of the women were sedentary. Regarding physical activity groups, women spent more time on household activities followed by recreational activities. CONCLUSION:The physical activity pattern observed was inadequate form the beginning of pregnancy and it worsened in the third gestational trimester.CNP

Factors associated with preterm birth in Campina Grande, Paraiba State, Brazil: a case-control study

A case-control study (2008-2009) analyzed risk factors for preterm birth in the city of Campina Grande, Paraiba State, Brazil. A total of 341 preterm births and 424 controls were included. A multiple logistic regression model was used. Risk factors for preterm birth were: previous history of preterm birth (OR = 2.32; 95% CI: 1.25-4.29), maternal age (OR = 2.00; 95% CI: 1.00-4.03), inadequate prenatal care (OR = 2.15; 95% CI: 1.40-3.27), inadequate maternal weight gain (OR = 2.33; 95% CI: 1.45-3.75), maternal physical injury (OR = 2.10; 95% CI: 1.22-3.60), hypertension with eclampsia (OR = 17.08; 95% CI: 3.67-79.43) and without eclampsia (OR = 6.42; 95% CI: 3.50-11.76), hospitalization (OR = 5.64; 95% CI: 3.47-9.15), altered amniotic fluid volume (OR = 2.28; 95% CI: 1.32-3.95), vaginal bleeding (OR = 1.54; 95% CI: 1.01-2.34), and multiple gestation (OR = 22.65; 95% CI: 6.22-82.46). High and homogeneous prevalence of poverty and low maternal schooling among both cases and controls may have contributed to the fact that socioeconomic variables did not remain significantly associated with preterm birth

Systemic Manifestations, Tooth Eruption and Enamel Defects in Children with Congenital Zika Virus Syndrome: 36-Month Follow-up Case Series

Objective:&nbsp;To describe systemic manifestations, the characteristics related to tooth eruption, and the occurrence of enamel defects in children with Congenital Zika Virus Syndrome (CZS).&nbsp;Material and Methods:&nbsp;Prospective case series based on nine children with confirmed CZS diagnosis assisted at a reference center in a municipality in the Northeast Region of Brazil. Through a structured interview directed to mothers, information related to prenatal, delivery, and postpartum periods was collected. Tooth eruption was monitored through clinical examinations for 36 months. The modified developmental defect of enamel index (DDE) was used to identify opacities and hypoplasia. Data were presented using descriptive statistics.&nbsp;Results:&nbsp;A high proportion (77.8%) had microcephaly, and 55.5% had low birth weight. Musculoskeletal disorders, swallowing difficulty, and self-injury practices were present in all children. Among the systemic findings, visual impairment (77.8%) and seizures (77.8%) were widely reported. Concerning disorders related to the stomatognathic system, bruxism (66.7%) and difficulty in sucking (33.3%) were present. For most children (77.8%), the deciduous right lower central incisor was the first tooth to erupt (minimum 8 months and maximum 17 months). Enamel defects were diagnosed in only two children (22.2%).&nbsp;Conclusion:&nbsp;A wide range of systemic manifestations was observed in children with CZS, including visual impairment and musculoskeletal disorders. Delayed eruption of the first deciduous tooth was also observed. Enamel defects were present in a small proportion of children
