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 tissue ~~s~~ 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.本数据集源自一项前瞻性研究，该研究对比了孕妇腹部脂肪组织超声测量结果与住院分娩期间的妊娠结局。数据采集于巴西阿雷格里港的低风险门诊诊所，采集时段为2016年10月至2017年12月。初始纳入的272名受试者中，61名（22%）失访，最终有效样本量为211例。 基线阶段，对所有纳入受试者均实施常规产科超声检查，并完成孕妇上腹部脂肪测量。共开展两项评估：孕妇上腹部内脏脂肪组织（preperitoneal m-VAT）与孕妇上腹部皮下脂肪组织（preperitoneal m-SAT）。对于妊娠20周前纳入的受试者，额外增加脐周脂肪评估，具体涵盖：孕妇脐周内脏脂肪组织（periumbilical m-VAT）与孕妇脐周皮下脂肪组织（periumbilical m-SAT）。基线时还收集了受试者的人体测量学、营养及人口统计学特征相关数据。妊娠结局通过住院病历进行确认，以明确妊娠、分娩及新生儿状况。 本数据集共包含116个变量，涵盖基线阶段采集的人口统计学、超声、营养及实验室检查特征。此外，数据集还收录了分娩过程及产后时期的新生儿相关数据。研究对回顾性收集的妊娠异常数据进行了重点标注。本数据集可为后续旨在评估孕妇腹部脂肪对异常妊娠结局预测能力的相关研究提供支撑。

背景概述

该数据集是一项前瞻性研究，收集了211名孕妇在孕期的腹部脂肪超声测量（包括内脏和皮下脂肪厚度）以及营养评估数据，旨在分析这些因素与妊娠结局（如分娩和新生儿状况）的关联。数据集包含116个变量，覆盖人口统计学、超声测量、营养和实验室特征，并提供了详细的数据字典和观察记录，适用于研究母体脂肪对异常妊娠结局的预测能力。
