Maternal reporting of prenatal ultrasounds among women in the National Birth Defects Prevention Study

Abstract

Background Increased availability and usage of ultrasound screening have led to improved identification of fetal structural abnormalities prenatally. Few population‐based studies have been published on prenatal detection for structural birth defects in the United States. The aim of this study is to determine the frequency of maternal reporting of abnormal prenatal ultrasounds for selected birth defects and to investigate associated maternal characteristics. Methods Participants included 4013 mothers enrolled in the National Birth Defects Prevention Study who carried a fetus with at least one of 14 structural birth defects between 1997 and 2004. Frequencies of abnormal prenatal ultrasounds were based on maternal report and computed for isolated and multiple defects. Associations between maternal characteristics and abnormal prenatal ultrasounds were assessed using logistic regression. Results Overall, 46% of participants reported an abnormal ultrasound. Infants with omphalocele, anencephaly, gastroschisis, and renal agenesis were more likely to have abnormal prenatal ultrasounds than those with cleft and limb abnormalities. Hispanic women were less likely to report abnormal prenatal ultrasounds of birth defects than Caucasians, as were women who had a body mass index ≥ 30 kg/m2 compared with those with a normal body mass index. CONCLUSION Of the 14 selected birth defects in this study, less than half were reported by mothers of affected infants to have had an abnormal ultrasound during pregnancy. The frequency of reporting abnormal prenatal ultrasounds varies by type of defect, maternal race/ethnicity, and maternal body mass index status.

Câncer De Mama Em Rio Grande, Rio Grande Do Sul Entre 2010-2019: Variáveis Hospitalares Prévias a Pandemia Por Covid-19

“…Este período foi marcado por uma mudança na série histórica da microcefalia no SINASC. e do tipo de parto, antecipação de cuidados de subespecialidades, bem como a condução do aconselhamento familiar sobre prognóstico e gestão terapêutica(WEEDN et al, 2013). Métodos de diagnóstico por imagem, especialmente ultrassom transvaginal e tridimensional de alta resolução, bem como a ressonância magnética, têm sido uma ferramenta importante na avaliação pré-natal de malformações do SNC, permitindo diagnósticos cada vez mais precisos(POOH, 2012).A ultrassonografia pré-natal (USG) é um método muito eficiente na detecção de anomalias congênitas importantes, mas falta especificidade, que é essencial para o diagnóstico da síndrome.…”

Detection of Structural Abnormalities and Ultrasonic Soft Markers in the First Trimester Screening

“…To solve this problem, medical research continues to prevent the emergence of birth defects. There are some effective ways to reduce the incidence of birth defects in infants, such as, reduce the risk factors that lead to birth defects and improve the rate of early diagnosis of fetal malformations during pregnancy [1,2] . Ultrasonography as a means of prenatal diagnosis plays a very important role in detecting fetal malformation and involved in saving the fetus [3] .…”
