Maternal history of adoption or foster care placement in childhood: a risk factor for preterm birth

The aim of our study was to explore the risk factors for very preterm (gestation under 32 weeks) and moderate preterm birth (gestation weeks 32-36 6/7) in singleton pregnancies in a national retrospective cohort study. We also wanted to establish whether IVF/ICSI is an independent risk factor for preterm birth after adjusting for already known confounders. We used data for 267 718 singleton births from 2002-2015 from the National Perinatal Information System of Slovenia, containing data on woman, pregnancy, birth, the postpartum period, and the neonate for each mother–infant pair. Mode of conception, maternal age, education, BMI, parity, smoking, history of cervical excision procedure, history of hysteroscopic resection of uterine septum, presence of other congenital uterine malformations, bleeding in pregnancy, preeclampsia or HELLP and maternal heart, and pulmonary or renal illness were included in the analyses. Unadjusted OR for very preterm birth after IVF-ICSI was 2.8 and for moderate preterm birth was 1.7. After adjusting for known confounders, the OR was still significantly elevated (1.6 and 1.3, respectively). Risk factors for very preterm birth with OR higher than 2.4 were history of cervical excision procedure, resection of uterine septum, operation or having other congenital uterine malformations, and bleeding in pregnancy. Risk factors for very preterm birth with OR between 1.4 and 2.1 were age >35 years, being underweight or obese, not having professional education, smoking, first birth, preeclampsia/HELLP, and IVF/ICSI. Risk factors for moderate preterm birth with OR higher than 2.4 were history of cold knife conization and other congenital uterine malformations. We found that even after adjustment, IVF/ICSI represents a single risk factor for early and late preterm birth even after adjustment with other risks such as maternal age, smoking, or a history of invasive procedures for either cervical intraepithelial neoplasia or infertility treatment.

Background: Currently preterm labour is one of the most challenging problems confronting the obstetricians and perinatologists. This unfortunate episode accounts for 50-75% of the perinatal mortality. Methods: A cross sectional study was conducted on 210 pregnant women with preterm labour admitted in Monno Medical College Hospital, Manikganj from June 2014 to December 2015, to study the causes and outcome of preterm birth in Tertiary health centre of Manikganj. Results: Occurence of preterm birth was 13.82%; 47.14% occured between 34-37 weeks of gestation; 33.80% occured 31-33 weeks of gestation and occurred in 28-30 weeks 19.04%. About 22% patients presenting with preterm labour had a past history of abortions and 14.3% had a history of preterm delivery. Premature rupture of membranes was found to be the most common risk factor related with preterm labour in the present pregnancy. Genitourinary tract infection was the next important risk factor of preterm labour; 24.8% (86) patients had either vaginal infection (19.5%) or urinary infection (21.4%) or both. Another important risk factor identified in this study was antepartum haemorrage which was cause in 11.4 % cases. Preterm babies commonly suffered from various complications like jaundice (32.1%), respiratory distress syndrome (22.6%), asphyxia (13.5%), sepsis, hypoglycemia and coagulopathy. Conclusion: Most of the preterm births occured between 34-37 weeks of gestation. Most common risk factors of preterm births are history of abortion and preterm delivery in previous pregnancy; PROM UTI vaginal infection, PIH and APH in correct pregnancy. Newborn jaundice, RDS and birth asphyxia are the common neonatal morbidity in preterm labour. Identifying risk factors to prevent the onset of preterm labour and advanced neonatal care unit can help decrease neonatal morbidity and mortality.

El parto pretérmino es un problema de salud a nivel mundial. En la medicina perinatal continúa siendo una de las complicaciones más frecuentes, de ahí que la mayor parte de las muertes neonatales ocurren en nacidos prematuros. El objetivo de este estudio fue determinar la relación entre el aborto previo como factor de riesgo para el desarrollo de parto pretérmino en gestantes ingresadas en al área de emergencias y hospitalización del Hospital Básico Jipijapa. Este trabajo se desarrolló como una investigación cualicuantitativa, retrospectiva, descriptiva y transversal. Las características sociodemográficas de las pacientes con antecedentes de abortos previos y parto pretérmino mostraron que las menores de 18 años, casadas, residentes en zonas urbanas y con nivel de instrucción secundaria fueron la mayoría. Se determinó que el aborto previo predominante fue espontáneo, de dos o tres. La edad gestacional del aborto fue menor a 12 semanas, el tiempo entre la ocurrencia del aborto y el embarazo que culminó en un parto pretérmino fue de 6 meses y la complicación del aborto más presentada fue el aborto séptico. La edad gestacional y el peso al nacer de los pretérminos que tuvieron antecedentes maternos de aborto previo, en su mayoría fue mayor a 32 semanas y con un peso superior a los 2 500 gramos. Palabras clave: Aborto previo, factor de riesgo, parto pretérmino. Abstract Preterm birth is a global health problem. In perinatal medicine, it continues to be one of the most frequent complications, hence the majority of neonatal deaths occur in premature births. The objective of this study was to determine the relationship between previous abortion as a risk factor for the development of preterm birth in pregnant women admitted to the emergency area and hospitalization of the Jipijapa Basic Hospital. This work was developed as a qualitative-quantitative, retrospective, descriptive and cross-sectional investigation. The sociodemographic characteristics of the patients with a history of previous abortions and preterm delivery showed that those under 18 years of age, married, living in urban areas and with a secondary education level were the majority. It was determined that the predominant previous abortion was spontaneous, of two or three. The gestational age of the abortion was less than 12 weeks, the time between the occurrence of the abortion and the pregnancy that culminated in preterm delivery was 6 months, and the most common complication of the abortion was septic abortion. The gestational age and birth weight of the preterm who had a maternal history of previous abortion, were mostly greater than 32 weeks and with a weight greater than 2 500 grams.

Objective To determine the prevalence of genital mycoplasma infection and the risk of spontaneous preterm birth (sPTB) in asymptomatic pregnant women. Design Prospective cohort. Setting Public and private health services in Ribeirão Preto-SP, Brazil. Population 1.349 asymptomatic women with a singleton pregnancy at 20-25 weeks of gestation (WG) recruited between 2010 and 2011. Methods Baseline data was assessed using a questionnaire, in addition to cervicovaginal fluid and blood samples, to analyze lower reproductive tract infections (RTIs) and immune mediators, respectively. The association between variables and the risk of sPTB was evaluated using logistic regression analysis to estimate the odds ratios (ORs). Main outcome measures Genital mycoplasma infection and prematurity. Results The prevalence of the sPTB and genital mycoplasma was 6.8% and 18%, respectively. The infection was not a risk factor for sPTB (aOR 0.66; 95% CI 0.32-1.35), even when associated with bacterial vaginosis (BV). However, it was associated with a low socioeconomic status (p=0.0470), cigarette use (p=0.0009), number of sexual partners (p=0.0019), and BV (p<.0001). Regarding the risk factors associated with sPTB, previous history of PTB (aOR 12.06; 95% CI 6.21-23.43) and a cervical length ≤ 2.5 cm (aOR 3.97; 95% CI 1.67-9.47) were significant. Conclusions The risk of sPTB was independently associated with the history of PTB and the cervical length but not with the genital mycoplasma infection.
