The Apgar Score relates to fetal data and is a method to quickly summarise the health of newborn children against infant mortality. Apgar stands for "Appearance, Pulse, Grimace, Activity, and Respiration". All the figures were generated from the data described in <b>Results27112017.txt.</b><br>The aim of this retrospective cohort study was to analyse the influence of BMI, demographic, obstetric and anesthesia-associated factors on adverse maternal-fetal outcomes in pregnant women under regional labor analgesia. For example identifying the relationship between BMI and the occurrence of systemic diseases in parturient women receiving regional labor analgesia can help health care organisations to improve the assistance provided for these women during their hospitalisation. <br>The study was conducted from November 2012 to May 2016 in the Maternity School Hospital, Federal University of Rio de Janeiro. A total of 685 patients participated in the study. Data presented in the related article were collected from charts of pregnant women who were evaluated during hospital admission (with a single fetus aged above 36 weeks) and who reached the labor active phase either spontaneously or by induction. This informational was dated by the first trimester ultrasound, in which the child was in the longitudinal position, without malformation and with good vitality. The pregnant women who received complete prenatal care and those who were attended in their preanesthetic visit (classified as II or III as recommended) were included and subjected to regional labor analgesia during labor.<br>Anthropometric data (such as pregestational BMI and ages), clinical data (such as intercurrent systemic diseases like diabetes, and the ASA classification), obstetric history data (such as parity and gestational age) and intrapartum obsteric interventions data (such as induction of labor and intrapartum use of oxytocin) were collected for each patient. The patients underwent regional anesthesia. Regional analgestic techniques used in this study were as follows: continuous (epidural or combined) or simple subarachnoid anesthesia. <br>The outcome variables were divided into three groups: maternal data (such as type of delivery and maternal hospitalisation time in days), fetal data (such as breastfeeding in the first hour of life and neonatal birth injury) and anesthetic data (such as time of analgesia and anesthetic complications.<br>The data collected were organised in Microsoft Excel spreadsheets and statistical analysis was performed using the R Core Team 2016 program. The data obtained were processed for descriptive statistical analysis of association and regression. <br><br><br><br>
