Maternal fat ultrasound measurement and nutritional assessment during pregnancy: A dataset centered in gestational outcomes

This dataset was collected as part of a prospective study in which abdominal maternal fat tissues ultrasound measurements were compared with outcomes during hospitalization for labor and delivery. Data was collected in a low-risk outpatient clinic from October 2016 to December 2017 in Porto Alegre, Brazil. Of the 272 patients initially included, 61 (22%) were lost to follow-up, resulting in a final sample of 211 cases.

At baseline, a routine obstetric ultrasound was performed with a maternal epigastric fat measurement conducted in all included cases. Two assessments were performed: the epigastric maternal visceral adipose tissue (preperitoneal m-VAT) and the epigastric maternal subcutaneous adipose tissue (preperitoneal m-SAT).  Cases included before 20 weeks had an additional periumbilical fat assessment performed; this included: the periumbilical maternal visceral adipose tissue (periumbilical m-VAT) and  the periumbilical maternal subcutaneous adipose tissue (periumbilical m-SAT). Data regarding anthropometric, nutritional and demographic characteristics were assessed at baseline. Pregnancy outcomes were determined through hospital charts in order to establish pregnancy, labor and newborn conditions.

The dataset has 116 variables that include demographic, ultrasound, nutritional and laboratory characteristics measured at baseline. Likewise, it presents data related to the birth process and newborn conditions during the postpartum period. The pregnancy abnormalities data obtained retrospectively are highlighted. The dataset may be helpful for future studies that seek to assess the predictive capacity of maternal abdominal fat for abnormal pregnancy outcomes.

本数据集系一项前瞻性研究的组成部分，旨在对比分析妊娠期间腹壁母体脂肪组织的超声测量值与住院分娩期间的结局。研究数据采集于2016年10月至2017年12月间，在巴西的累西腓市一所低风险门诊诊所进行。在最初纳入的272名患者中，有61名（占比22%）因随访失联而剔除，最终样本量为211例。在基线阶段，对纳入的病例进行了常规产前超声检查，并对所有病例进行了母体上腹部脂肪测量。对纳入研究时妊娠周数小于20周的病例，还额外进行了脐周脂肪评估，包括脐周母体内脏脂肪组织（脐周m-VAT）和脐周母体皮下脂肪组织（脐周m-SAT）。基线时，对患者的体质、营养及人口统计学特征进行了评估。通过医院病历确定妊娠结局，以确定妊娠、分娩及新生儿状况。该数据集包含116个变量，涉及基线时测量的人口统计学、超声、营养和实验室特征，同样呈现了分娩过程及产后新生儿状况的数据。此外，对回顾性收集的妊娠异常数据进行了突出展示。该数据集有望为未来研究提供帮助，这些研究旨在评估母体腹部脂肪对异常妊娠结局的预测能力。
