Fármacos antiepilépticos usados en el embarazo y sus consecuencias sobre los resultados fetales: una revisión de la literatura / Antiepileptic drugs used in pregnancy and their consequences on fetal outcomes: a review of the literature

Los riesgos teratogénicos ocasionados por la exposición intrauterina a fármacos antiepilépticos (FAE) son conocidos, por lo que su prescripción se mantiene bajo estricto control. Describir los efectos adversos fetales de la exposición a FAE durante la gestación, reportados en la literatura durante el período 2016-2022. Revisión sistematizada de estudios que reportaron los efectos adversos fetales inducidos por la exposición a FAE en mujeres embarazadas en tratamiento por diagnósticos neurológicos, principalmente de epilepsia. La búsqueda se realizó en PubMed, Cochrane, Web of Science, SCOPUS, Biblioteca Virtual en Salud, Lilacs y SciELO. Se identificaron 37 artículos distribuidos en 13 países de Asia, Europa, América del Norte y Oceanía. Se observaron resultados perinatales adversos, tanto físicos como cognitivos, en la mayoría de los estudios. Los fármacos identificados como los más utilizados en los últimos años fueron valproato, topiramato, carbamazepina, lamotrigina y levetiracetam. Los FAE tienen potencial teratogénico en distintos grados de riesgo, provocando anomalías congénitas o efectos adversos en múltiples sistemas del cuerpo humano, siendo los sistemas nervioso, circulatorio y osteomuscular los más afectados.

The teratogenic risks caused by intrauterine exposure to antiepileptic drugs (AED) are known, so their prescription is kept under strict control. To describe the fetal adverse effects AED exposure during gestation, reported in the literature during the period 2016-2022. Systematized review of studies that reported fetal adverse effects induced for the exposure to AED in pregnant women in treatment for neurological diagnoses, mainly epilepsy. The search was carried out in PubMed, Cochrane, Web of Science, SCOPUS, Virtual Health Library, Lilacs and SciELO. 37 articles distributed in thirteen countries in Asia, Europe, North America and Oceania were identified. Adverse perinatal outcomes, both physical and cognitive, were observed in most studies. The most common drugs identified were valproate, topiramate, carbamazepine, lamotrigine and levetiracetam. AED have teratogenic potential in different degrees of risk, causing congenital anomalies or adverse effects in multiple systems of the human body, being the nervous, circulatory and musculoskeletal systems the most affected.

Enterocolitis necrosante posterior a evento aislado de taquicardia supraventricular: reporte de un caso de presentación neonatal atípica / Necrotizing enterocolitis after an isolated event of supraventricular tachycardia. Case report of atypical neonatal presentation

La taquicardia supraventricular (TSV) es la principal taquiarritmia en el recién nacido (RN) que requiere una resolución urgente. Por su parte, la enterocolitis necrosante (ECN) es la emergencia gastrointestinal más común que afecta principalmente a RN prematuros. Aunque estas se reconocen como patologías distintas, la bibliografía sugiere que los episodios de TSV pueden predisponer a los pacientes a la ECN a través de alteraciones en el flujo sanguíneo mesentérico y una disminución de la perfusión tisular. Se presenta aquí el caso clínico de un neonato prematuro que desarrolló un cuadro de ECN luego de un evento aislado de TSV con bajo gasto cardíaco

Supraventricular tachycardia (SVT) is the main tachyarrhythmia in the newborn (NB) that requires urgent resolution. Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency that mainly affects premature infants. Although these conditions are recognized as distinct pathologies, literature reports suggest that episodes of SVT may predispose patients to NEC secondary to disturbances in mesenteric blood flow and a decrease in tissue perfusion. We present here the clinical case of a premature neonate who developed NEC after an isolated SVT event with low cardiac output

Hipoglucemia neonatal en hijos de madres con diabetes mellitus gestacional. Comparación de la incidencia según el tratamiento materno / Neonatal hypoglycemia in infants born to mothers with gestational diabetes mellitus. Comparison of its incidence based on maternal treatment

Introducción. La hipoglucemia neonatal es una complicación de la diabetes mellitus gestacional Son pocos los estudios que avalan la pesquisa sistemática en este grupo poblacional durante las primeras horas de vida. Objetivos. Evaluar la asociación entre tratamiento materno recibido (dieta versus insulina) y el desarrollo de hipoglucemia, e identificar los factores de riesgo asociados. Población y métodos. Estudio observacional, analítico y retrospectivo realizado en en las sedes de Buenos AIres y San Justo de un hospital general de tercer nivel entre el 1 de enero de 2017 y el 31 de diciembre de 2018. Se estimó la incidencia de hipoglucemia (≤47 mg/dl) en recién nacidos según el manejo de la diabetes materna y se realizó un análisis multivariable para evaluar factores asociados. Resultados. Se incluyeron 195 pacientes. No se encontró diferencia estadística en la incidencia de hipoglucemia según el tratamiento materno recibido (45,3 % versus 39,7 %; p = 0,45) ni se identificaron factores de riesgo asociados. Modificando el valor de corte a ≤40 mg/dl, tampoco se encontraron diferencias en la incidencia (23,4 % versus 19 %, p = 0,48); no obstante, los pacientes hipoglucémicos presentaron un hematocrito significativamente mayor y una menor prevalencia de lactancia exclusiva al egreso. El análisis multivariable mostró una asociación independiente entre alto peso al nacer con hipoglucemia que requiere corrección. Conclusiones. La incidencia de hipoglucemia neonatal en la población estudiada no presentó diferencia según el tratamiento materno recibido. El estudio realizado fundamenta el control de la glucemia en estos niños en la práctica diaria.

Introduction. Neonatal hypoglycemia is a complication of gestational diabetes mellitus. Few studies have been conducted to support a systematic screening in the first hours of life of this population group. Objectives. To assess the association between the treatment administered to the mother (diet vs. insulin) and the development of hypoglycemia, and to identify associated risk factors. Population and methods. Observational, analytical, and retrospective study carried out at the Buenos Aires and San Justo maternal centers of a general, tertiary care hospital between 01-01-2017 and 12-31-2018. The incidence of neonatal hypoglycemia (≤ 47 mg/dL) based on the management of maternal diabetes was estimated and a multivariate analysis was done to assess related factors. Results. A total of 195 patients were included. No statistical difference was found in the incidence of hypoglycemia based on the treatment administered to the mother (45.3% vs. 39.7%; p = 0.45) and no associated risk factors were identified. Once the cutoff point was changed to ≤ 40 mg/dL, no differences were found in the incidence either (23.4% versus 19%, p = 0.48); however, patients with hypoglycemia had a significantly higher hematocrit level and a lower prevalence of exclusive breastfeeding upon discharge. Multivariate analysis showed an independent association between a high birth weight and hypoglycemia, requiring correction. Conclusions. The incidence of neonatal hypoglycemia in the studied population did not vary based on the treatment received by the mother. This study supports the control of glycemia in these infants in daily practice.

Transfusão de hemácias em neonatos pelo cateter central de inserção periférica: revisão integrativa / Red blood cell transfusions in newborn infants through peripherally inserted central catheter: an integrative review / Transfusión de glóbulos rojos en neonatos a través de catéter central de inserción periférica: revisión integradora

Objetivo: identificar na literatura as implicações relacionadas à transfusão de hemácias, por meio do Cateter Central de Inserção Periférica, em neonatos. Métodos: revisão integrativa realizada nas bases de dados Web of Science, Scopus, Biblioteca Virtual em Saúde e PUBMED. Incluíram-se publicações em inglês, espanhol e português, disponíveis na íntegra, sem data limite. Resultados: selecionaram-se quatro (100,0%) pesquisas que abordaram hemólise das hemácias e dois deles (50,0%), também, versaram sobre obstrução do cateter durante a transfusão. Os estudos evidenciaram ocorrência de hemólise relacionada à velocidade de infusão e ao tempo de armazenamento das hemácias, porém sem relevância clínica. Referente à obstrução, observou-se ocorrência em apenas um cateter de 38 acompanhados em um estudo; no outro, não houve obstrução, sendo as transfusões consideradas tecnicamente viáveis. Conclusão: urgem estudos clínicos primários que avaliem as consequências clínicas das transfusões de hemácias por esse tipo de cateter, em neonatos.

Objective: this study aimed to identify in literature the implications related to red blood cell (RBC) transfusions, through Peripherally Inserted Central Catheter, in neonates. Methods: this is an integrative review conducted in the Web of Science, Scopus, Virtual Health Library, and PubMed databases. Publications in English, Spanish and Portuguese, available in full, without date limit, were included. Results: four (100.0%) studies that addressed hemolysis of RBCs were selected, of which two (50.0%) also addressed catheter obstruction during transfusion. Studies revealed the occurrence of hemolysis related to infusion rate and storage time of RBCs, however without clinical relevance. Regarding obstruction, it was verified in only one catheter out of 38 followed-up in a study; in the other, there was no obstruction and transfusions were considered technically feasible. Conclusion:there is urgent need for primary clinical studies to assess clinical consequences of red blood cell transfusions through this type of catheter in neonates.

Conclusión:se necesitan estudios clínicos primarios para evaluar las consecuencias clínicas de las transfusiones de glóbulos rojos a través de este tipo de catéter en los recién nacidos.

Estado nutricional de la mujer embarazada y su relación con las complicaciones de la gestación y el recién nacido / Nutrition status of pregnant women and its relationship with complications of pregnancy and the newborn

RESUMEN: El estado nutricional materno determina las condiciones de salud y nutricionales del recién nacido, así como las complicaciones durante el embarazo y el parto. Se realizó el estudio en 894 mujeres que tuvieron su parto en los Hospitales de la ciudad de Loja Ecuador durante el periodo enero - junio del 2019. Se determinó la antropometría de la madre y de su hijo, así como se tomó datos de complicaciones durante el embarazo y el parto, de su historia clínica. Además, se efectuó la correlación entre el estado nutricional pre-gestacional de la madre con el recién nacido, de igual forma con el estado de salud de la madre. El objetivo de este trabajo fue determinar el estado nutricional pre-gestacional y su relación con la condición de salud y nutricional del niño. El IMC pre-gestacional reportó 47,3 % de sobrepeso y obesidad y 2,6 % de bajo peso. En un porcentaje mayor al 10 % las madres con sobrepeso y obesidad tuvieron hijos grandes para la edad gestacional, de igual forma las madres con bajo peso tuvieron el 26,1 % recién nacidos pequeños. Las principales complicaciones de las madres relacionadas con sobrepeso y obesidad fueron: diabetes gestacional, hemorragia postparto y pre-eclampsia durante el embrazo. Importante señalar la alta frecuencia de infecciones de las vías urinarias 53,9 % (478); y vaginitis 22,3 % (199); aunque estas no están directamente relacionadas con procesos metabólicos como etiología, más si están favorecidos por ellos. Durante el parto la complicación más frecuente fue el parto distócico con un 8,9 % (77), además del total de partos el 41,8 % (374) terminaron en cesárea, de estos el 51, 6 % (193) corresponden a sobrepeso y obesidad. Las complicaciones del recién nacido fueron: Síndrome de dificultad respiratoria aguda, asfixia neonatal e hipoglicemia. En conclusión, el estado nutricional pre-gestacional de la madre está relacionado directamente con el estado de salud y nutricional del recién nacido.

SUMMARY: The maternal nutritional status determines the health and nutritional conditions of the newborn, as well as complications during pregnancy and childbirth. The study was carried out in 894 women who had their delivery in the Hospitals of the city of Loja Ecuador during the period January - June 2019. The anthropometry of the mother and her child was determined, as well as data on complications during pregnancy and delivery, from their clinical history. In addition, the correlation was made between the pre-gestational nutritional status of the mother with the newborn, in the same way with the health status of the mother. The objective of this work was to determine the pre-gestational nutritional status and its relationship with the health and nutritional condition of the child. The pre-gestational BMI reported 47.3 % overweight and obesity and 2.6 % underweight. In a percentage higher than 10 %, mothers with overweight and obesity had large children for gestational age, in the same way, mothers with low weight had 26.1 % small newborns. The main complications of the mothers related to overweight and obesity were: gestational diabe- tes, postpartum hemorrhage and pre-eclampsia during pregnancy. It is important to note the high frequency of urinary tract infections 53.9% (478); and vaginitis 22.3% (199; although these are not directly related to metabolic processes such as etiology, more if they are favored by them. During delivery, the most frequent complication was dystocic delivery with 8.9 % (77), in addition to the total deliveries 42.5 % (374) that ended in cesarean section, of which 51.6 % (193) correspond to overweight and obesity. The complications of the newborn were: Acute respiratory distress syndrome, neonatal asphyxia and hypoglycemia. In conclusion, the pre-gestational nutritional status of the mother is directly related to the health and nutritional status of the newborn.

RESUMEN Introducción: La depresión cardiorrespiratoria neonatal es un problema clínico que, en dependencia de su etiología, conduce a una alta morbilidad neurológica y elevada mortalidad. Objetivo: Caracterizar al recién nacido con depresión cardiorrespiratoria en el servicio de Neonatología del Hospital Ginecobstétrico "Fé del Valle Ramos", de Manzanillo, Granma. Método: Se realizó un estudio retrospectivo, observacional, descriptivo y transversal. Se seleccionaron 88 neonatos que cumplieron con los criterios de inclusión de recién nacido con depresión cardiorrespiratoria. Los datos se recolectaron durante el período de enero de 2017 a diciembre de 2018. Se tomaron en cuenta las siguientes variables: puntaje de Apgar, años de estudio, sexo, tipo de depresión cardiorrespiratoria, peso al nacer, factores maternos, edad gestacional y afecciones asociadas. Resultados: La depresión severa al nacer predominó en la mayoría de los neonatos (56,8 %). Prevalecieron los recién nacido de buen peso (73,9 %), nacidos a término (77,2 %). Las infecciones maternas (45,5 %) durante la gestación, el tiempo de rotura de membranas prolongado (31,8 %) y la presencia de líquido amniótico meconial (30,7 %), constituyeron los factores maternos que mayor vínculo guardaron con el neonato deprimido. Conclusiones: Las infecciones maternas, la rotura prematura de membranas, la presencia de líquido amniótico meconial, los nacimientos por cesárea, la nuliparidad, prematuridad y el embarazo en la adolescencia, son algunos de los factores de riesgo relacionados en este estudio que guardan vínculo estrecho con el predominio de estas afecciones en los neonatos deprimidos.

ABSTRACT Introduction: The cardiorespiratory depression in neonates is a clinical complication that, depending on its etiology, leads to high neurological morbidity and mortality. Objective: To characterize neonates with cardiorespiratory depression treated in the neonatology service at the Hospital Ginecobstétrico "Fé del Valle Ramos" in Manzanillo, Granma. Method: A retrospective, observational, descriptive and cross-sectional study was carried out. A total of 88 neonates with cardiorespiratory depression criteria were selected in the study. All information gathered includes the period January 2017 throughout December 2018. Variables assessed were as follow: Apgar score, years of study, sex, type of cardiorespiratory depression, birth weight, maternal factors, gestational age and associated conditions. Results: Severe depression at birth was predominant in most of neonates (56.8%). Newborn infants with a normal birth weight (73.9%), and born at term (77.2%) were predominant. Maternal infections during gestation (45.5%), prolonged rupture of membranes (31.8%) and the presence of meconium in the amniotic fluid (30.7%) were the maternal factors most associated with depressed neonate. Conclusions: The maternal infections, premature rupture of membranes, the presence of meconium in the amniotic fluid, cesarean birth, nulliparous status, premature and adolescent pregnancy are some of the risk factors assessed in this study that are closely linked to the prevalence of arising conditions in depressed neonates.

Differentiation of food protein-induced enterocolitis syndrome and necrotizing enterocolitis in neonates by abdominal sonography

Abstract Objectives: To summarize and differentiate abdominal ultrasound findings of necrotizing enterocolitis and food protein-induced enterocolitis syndrome. Methods: From January 2017 to December 2018, the abdominal ultrasound results of 304 cases diagnosed necrotizing enterocolitis or food protein-induced enterocolitis syndrome were retrospectively analyzed. The presence of pneumatosis intestinalis, portal venous gas, bowel wall thickening, intestinal motility, focal fluid collections and hypoechoic change of gallbladder wall were calculated, and the results were compared and analyzed. Results: Pneumatosis intestinalis, portal venous gas, bowel wall thickening, intestinal motility weakened/absent, focal fluid collections and hypoechoic change of gallbladder wall can be found in both necrotizing enterocolitis and food protein-induced enterocolitis syndrome infants. However, in infants with necrotizing enterocolitis, intestinal motility was weakened/absent in whole abdomen, and in food protein-induced enterocolitis syndrome, it only involved isolated segment of bowel. The positive rates of above signs in necrotizing enterocolitis infants were significantly higher than those in food protein-induced enterocolitis syndrome (p < 0.01). Moreover, it was observed that the rate of weakened intestinal motility besides the lesion segment of bowel in necrotizing enterocolitis infants was 100%, and in food protein-induced enterocolitis syndrome infants, it was 0%, which is supposed to be a main sign for identification. Conclusion: In the early stage, abdominal ultrasound can be used to differentiate necrotizing enterocolitis and food protein-induced enterocolitis syndrome.

Complicaciones obstétricas y perinatales en mujeres infértiles que se embarazan / Obstetric and perinatal complications in infertile women who become pregnant

Las pacientes infértiles tienen un riesgo aumentado de resultados obstétricos y perinatales adversos que dependen de los factores de infertilidad subyacentes previos y de factores inherentes a los tratamientos recibidos para lograr el embarazo. La edad materna, las patologías previas ginecológicas, hormonales, endocrinológicas, metabólicas y anatomo funcionales son reconocidas como factores de riesgo para resultados adversos obstétricos y perinatales. Los tratamientos como la hiperestimulación ovárica y los tratamientos de reproducción asistida condicionan riesgos adicionales, especialmente por el aumento de embarazos múltiples que se generan con estas terapias. El aumento de la edad materna de pacientes tratadas por infertilidad y la necesidad creciente de tratamientos de reproducción asistida determinan probablemente, un mayor riesgo futuro de complicaciones obstétricas y perinatales. Muchos de estos factores de riesgo pueden ser modificados y manejados antes de iniciar los tratamientos con la finalidad de mejorar el pronóstico para la madre y el recién nacido. La consideración de estos factores de riesgo y sus consecuencias en el embarazo son parte esencial del consejo reproductivo que debiera recibir toda paciente que se somete a tratamientos por infertilidad.El objetivo de esta revisión es mostrar la relación existente entre las pacientes que consultan por infertilidad, los tratamientos usados y los potenciales riesgos obstétricos y perinatales cuando se produce el embarazo.

Infertile patients have an increased risk of adverse obstetric and perinatal outcomes that depend on underlying infertility factors and on those treatments recieved to become pregnant. Maternal age, hormonal, endocrinologial, metabolic and anatomic/functional gynecological diseases are widely recognized risk factors for adverse obstetric and perinatal outcomes. Infertility treatments like controlled ovarian hyperstimulation and assisted reproductive technologies add aditional risks, specially related to multiple pregnancies that are associated to. The higher maternal age of patients seeking for infertility treatment and the increasing need of assisted reproductive technologies probably determines a higher and increasing risk of obstetric and perinatal adverse outcomes. In many cases risk factors can be adequately modified and controlled before treatments are initiated thus improving maternal and neonatal prognosis. This risk factors and their consequences in pregnancy have to be strongly considered in reproductive counselling that should recieve every patient treated for infertility.The aim of this article is to show the relation between infertile patients seeking for treatment and their potential risks of obstetric and perinatal adverse outcomes when they get pregnant.

Cribado de infección por citomegalovirus congénito en recién nacidos de alto riesgo / Congenital cytomegalovirus infection screening in high risk newborn

INTRODUCCIÓN: La infección congénita por citomegalovirus (CMVc) es la causa más frecuente de infección intrauterina, 90% de los recién nacidos (RN) son asintomáticos al nacer y 6 a 15% desarrollarán secuelas a largo plazo, siendo la principal etiología de hipoacusia sensorio-neural no-genética. OBJETIVO: Determinar la prevalencia de CMVc en RN de alto riesgo. PACIENTES Y MÉTODO: Estudio de cohorte prospectivo, incluyó RN hospitalizados, con uno o más de los siguientes criterios: peso de nacimiento < 1.500 g, < 32 semanas edad gestacional (EG), pequeños para edad gestacional (PEG) severos, sospecha de infección congénita o que "no pasan" en estudio auditivo al nacer, además de hijos de madre con infección por VIH. Se realizó reacción de polimerasa en cadena para CMV en orina antes de 21 días de vida. RESULTADOS: Se enrolaron 193 RN. Prevalencia global CMVc 2,6% (n: 5) y por grupo de riesgo: 1/3 (n: 1) en RN con sospecha activa de infección congénita, 8,3% en RN con resultado "no pasa" en estudio auditivo, 4,9% en hijos de madre con infección por VIH, 3,3% en PEG severo y 1,7% < 1500 g, ninguno con asociación significativa. Sólo un paciente con CMVc fue sintomático, quien falleció en el período neonatal y los restantes RN con CMVc (asintomáticos) tienen seguimiento auditivo normal. DISCUSIÓN: La prevalencia reportada es comparable a las internacionales. Recomendamos cribado de CMVc, al menos en grupos de riesgo, siendo lo ideal el cribado universal. Esto permitiría su tratamiento oportuno y un seguimiento activo.

BACKGROUND: Congenital cytomegalovirus infection (cCMV) is the most frequent cause of congenital infection, 90% of affected newborn (NB) are asymptomatic at birth and 6-15% will develop long term sequalae. It is the main etiology of non-genetic sensorineural hearing loss. AIM: To determine prevalence of CMV in high risk NB. Methods: Cohort prospective study, including inpatient NB with one or more of following criteria: birth weight < 1,500 g, < 32 weeks gestational age (GA), severe small for gestational age (SGA), suspected congenital infection or "refer" in newborn hearing test, also NB to HIV-infected mothers. Urine CMV polymerase chain reaction was performed within 21 day of life. RESULTS: 193 NB were enrolled. Global cCMV prevalence 2.6% (n: 5) and by risk group: one third (n: 1) in NB with suspected congenital infection, 8.3% in NB with "refer" result in hearing test, 4.9% in NB to HIV-infected mothers, 3.3% in severe SGA and 1.7% in < 1,500 g, none with significant association. Only one symptomatic cCMV was detected who died in neonatal period and the remaining (asymptomatic) cCMV patients have normal hearing follow-up. DISCUSSION: Reported prevalence was comparable to international reports. We recommend cCMV screening, at least in risk groups, being ideal the universal screening. This would allow timely treatment and active follow-up.

Efficacy of abdominal ultrasound inspection in the diagnosis and prognosis of neonatal necrotizing enterocolitis

OBJECTIVE: This study aimed to identify the most useful ultrasound (US) features associated with definite neonatal necrotizing enterocolitis (NEC) and their prognostic values, particularly the calculated markers combined with important features. METHODS: A total of 213 suspected NEC cases were collected from the neonatal department of our hospital from January 2015 to August 2017. Each infant received both X-ray and US examinations. RESULTS: No differences were found in sex composition and delivery modes between groups. NEC-positive neonates had poorer prognosis compared to negative ones. The NEC group showed a higher frequency of abnormal signals. US showed higher NEC-related frequencies in different parameters. A variable (named predictor in US [PUS]) with five features was constructed. For NEC diagnosis, this variable provided a much higher area under the curve Q2 (AUC) (0.965) than other parameters. In this model, PUS had a cutoff value of 0.376 with a 0.900 sensitivity and 0.922 specificity. In prognosis, the closest factors were selected to draw a receiver operating characteristic curve, as well as a novel calculated variable US prognostic (USPro) marker. USPro had a much higher AUC (0.86) than other single features and showed a cutoff value of 0.18145, with 0.75 sensitivity and 0.84 specificity. This variable had a weaker power in prognosis when compared with PUS in diagnosis. CONCLUSIONS: The application of abdominal color Doppler US can provide high accuracy and sensitivity in NEC diagnosis and also contribute to its prognosis, without induction of radiation. Suspected neonates should be examined using this technique as early as possible.

Prevalence of active and passive smoking during pregnancy: a cross-sectional study / Prevalência de tabagismo ativo e passivo durante a gravidez: estudo transversal

Purpose: The aim of the present study was to evaluate the prevalence of active and passive smoking during pregnancy and its association with sociodemographic indicators, as well as perinatal and postnatal outcomes in newborns. Methods: This cross-sectional study was comprised of 431 pairs of mothers/ newborns. The study variables were: preterm birth, birth weight, oral mucosal lesions, sociodemographic indicators and smoking data. We collected data from medical records and through a self-administered questionnaire answered by mothers. A pediatric dentist examined the newborns for oral mucosal lesions. Bivariate and multivariate logistic regression models were used to evaluate the association between active and passive smoking and the other variables (α=5%). Results: The prevalence of active (9.5%) and passive smoking (4.2%) during pregnancy was low. Active smoking was statistically associated with low birth weight (OR: 2.4; 95%CI:1.1-5.3), lower schooling level (OR: 0.2; 95%CI:0.1-0.5) and mothers aged ≥36 years old (OR: 4.9; 95%CI:1.2-20.0). Passive smoking was not statistically associated with the other variables. There was no association between active or passive smoking during pregnancy and premature birth and oral lesions of the newborn. Conclusions: The prevalence of active and passive smoking were low. Active smoking was associated with low birth weight, maternal age and mother's schooling, suggesting a social influence of smoking behavior among a population with a lower educational level. There was no association between active and passive smoking and prematurity and oral lesions of the newborn. (AU)

Objetivo: O objetivo do estudo foi avaliar a prevalência de tabagismo ativo e passivo durante a gestação e a associação entre indicadores sociodemográficos, bem como desfechos pré e pós-parto em recém-nascidos. Metodologia: Este estudo transversal foi composto por 431 pares de mães/recém-nascidos. As variáveis estudadas foram: nascimento prematuro, peso ao nascer, lesões mucosas orais, indicadores sociodemográficos e dados sobre tabagismo. Coletamos dados por meio de prontuários e por questionário auto-aplicado respondido pelas mães. Um dentista pediátrico examinou os recém-nascidos para lesões mucosas orais. A regressão logística foi utilizada para a análise bivariada e multivariada dos dados (α=5%). Resultados: Prevalência de tabagismo ativo (9,5%) e tabagismo passivo (4,2%) durante a gravidez foi baixo. O tabagismo ativo foi estatisticamente associado ao baixo peso ao nascer (OR: 2,4; 95%CI:1,1-5,3), às mães com menor escolaridade (OR: 0,2; 95%CI:0,1-0,5), e mães com idade ≥36 anos (OR: 4,9; 95%CI:1,2-20,0); enquanto o tabagismo passivo não esteve estatisticamente associado a nenhuma variável. Não houve associação entre tabagismo durante a gestação com nascimento prematuro e lesões orais de recém-nascidos. Conclusões: As prevalências de tabagismos passivo e ativo foram baixas. O tabagismo ativo esteve associado ao baixo peso ao nascer, à idade materna e à escolaridade da mãe, sugerindo influência social do comportamento do tabagismo entre a população com menor escolaridade. Não houve associação entre tabagismo ativo e passivo com prematuridade e lesões de mucosa oral em recém-nascido. (AU)
