A comparison of obstetric outcomes in adolescent pregnancies and adult pregnancies

The prevalence of adolescent pregnancy and its associated consequences in the Eastern Mediterranean region: a systematic review and meta-analysis

BACKGROUND

Adolescent pregnancy is one of the public health problems that both mother and baby suffer from its consequences. This study was conducted to estimate the prevalence and consequences of adolescent pregnancy in the Eastern Mediterranean region.

METHODS

In this systematic review and meta-analysis, four databases (PubMed, ProQuest, Web of Science and Scopus) were systematically searched for relevant articles published from 1990 to 2022. The screening process for articles was conducted in accordance with the PRISMA guidelines. Joanna Briggs checklists were used to assess the quality of included studies. A random effects model was performed for the meta-analysis. Narrative synthesis of adolescent pregnancy prevalence, as well as a meta-analysis of adolescent pregnancy prevalence was performed using STATA 14.

RESULTS

The review included 12 studies and 94,189 study participants. The prevalence of adolescent pregnancy was [9% (95% CI 6.9, 11.2, p < 0.001)]. Pregnancy outcomes included preeclampsia [12.9%(95% CI 7.3,18.5, p < 0.001)], low birth weight [16.1%(95% CI 7.4-24.8, p < 0.001)], anemia [33%(95% CI 14.4, 51.7, p < 0.001)], and cesarean delivery [15.9%(95% CI 11.1-20.7, p < 0.001)].The results showed that 16.9% of deliveries were cesarean sections.

CONCLUSION

The study's findings indicate that adolescent pregnancy is prevalent in the Middle East region and is associated with negative outcomes for teenagers. Therefore, it is necessary to carry out effective interventions to reduce adolescent pregnancy.

Childhood abuse and perinatal outcomes for mother and child: A systematic review of the literature

Childhood abuse can have long-term adverse outcomes in adulthood. These outcomes may pose a particular threat to the health and well-being of perinatal women; however, to date, this body of knowledge has not been systematically collated and synthesized. This systematic review examined the child abuse literature and a broad range of perinatal outcomes using a comprehensive search strategy. The aim of this review was to provide a clearer understanding of the distinct effect of different abuse types and areas where there may be gaps in our knowledge. Following PRISMA guidelines, EBSCO, PsychInfo, Scopus, Medline, CINAHL, PubMed, and Google Scholar databases and gray literature including preprints, dissertations and theses were searched for literature where childhood abuse was associated with any adverse perinatal outcome between 1969 and 2022. Exclusion criteria included adolescent samples, abuse examined as a composite variable, editorials, letters to the editor, qualitative studies, reviews, meta-analyses, or book chapters. Using an assessment tool, two reviewers extracted and assessed the methodological quality and risk of bias of each study. From an initial 12,384 articles, 95 studies were selected, and the outcomes were categorized as pregnancy, childbirth, postnatal for the mother, and perinatal for mother and child. The prevalence of childhood abuse ranged from 5-25% with wide variability (physical 2-78%, sexual 2-47%, and emotional/psychological 2-69%). Despite some consistent findings relating to psychological outcomes (i.e., depression and PTSD), most evidence was inconclusive, effect sizes were small, or the findings based on a limited number of studies. Inconsistencies in findings stem from small sample sizes and differing methodologies, and their diversity meant studies were not suitable for a meta-analysis. Research implication include the need for more rigorous methodology and research in countries where the prevalence of abuse may be high. Policy implications include the need for trauma-informed care with the Multi-level Determinants of Perinatal Wellbeing for Child Abuse Survivors model a useful framework. This review highlights the possible impacts of childhood abuse on perinatal women and their offspring and areas of further investigation. This review was registered with PROSPERO in 2021 and funded by an internal grant from Charles Sturt University.

Adolescent pregnancies in Turkey: a single center experience

BACKGROUND

Adolescent pregnancies are more likely to be complicated with adverse perinatal outcomes.

OBJECTIVE

Assess the sociodemographic and clinical characteristics of adolescents who have delivered singleton newborns.

DESIGN

Retrospective cohort.

SETTINGS

A tertiary training and research hospital in Turkey.

PATIENTS AND METHODS

This was a review of adolescents and adults who delivered singleton newborns at a tertiary health center between January 2018 and June 2022. Pregnant adolescents were aged <20 years.

MAIN OUTCOME MEASURES

Adverse maternal and perinatal outcomes.

SAMPLE SIZE

2233 pregnant women (754 adolescents and 1479 adults).

RESULTS

Turkish nationality was significantly less prevalent in pregnant adolescents than pregnant adults (P=.001). Oligohydramnios, fetal growth restriction, perineal injury and postpartum intravenous iron treatment were significantly more prevalent in pregnant adolescents than pregnant adults (P<.05 for all). The neonates born to adolescent mothers had significantly lower birth weight and first minute Apgar score than the neonates born to adult mothers (P=.001 for both). Small for gestational age, need for intensive care and death were significantly more prevalent in neonates born to adolescent mothers than those born to adult mothers (P=.001 for all). Compared with pregnant adults, pregnant adolescents had a significantly higher risk of oligohydramnios (P=.001), preterm delivery (P=.024), intravenous iron treatment (P=.001), and small for gestational age (P=.001).

CONCLUSION

Due to the refugee population received by Turkey, it would be prudent to expect more frequent adolescent pregnancies. Adolescent pregnancies are more likely to be complicated with low birth weight, oligohydramnios, preterm delivery, postpartum iron treatment, lower Apgar scores, need for neonatal intensive care and neonatal death.

LIMITATION

Retrospective.

Adolescent Pregnancy: A Case-Series Study of 112 Adolescent Mothers and Their Newborns

Background

Although declining, adolescent pregnancy remains an important health concern and is associated with adverse maternal and fetal outcomes. We aimed to characterize adolescent pregnancy in a level II hospital and the observed maternal, fetal, and perinatal complications.

Methods

We conducted a case-series study of five-years duration with adolescent mothers and their newborns. We collected sociodemographic, obstetric, and neonatal data through chart review and conducted a comparison analysis between newborns who needed hospitalization and those who did not.

Results

We identified 112 newborns with adolescent mothers. Most pregnancies were unplanned (89.3%) and the start of pregnancy surveillance was late. The most frequent complications were intrauterine growth restriction, oligohydramnios, and threatened preterm labor. Prematurity was found in 9.8% of the newborns and 0.9% had less than 32 weeks at the time of birth. Thirteen newborns (11.6%) needed hospitalization in the neonatal intensive care unit, with three (23%) needing invasive ventilation. The main diagnoses of admission were prematurity, social risk, low birth weight, feeding difficulties, and newborn respiratory distress syndrome. Hospitalization seemed associated with less frequent breastfeeding. Among the hospitalized newborns, there was a high rate of discharge at the care of a relative or an institution (30.8%). Surprisingly, surveillance during pregnancy did not seem to differ between newborns that needed hospitalization and those that did not.

Discussion

Adolescent pregnancy is associated with poor surveillance as well as obstetric and neonatal complications. Newborns of adolescent mothers have a high hospitalization rate, but further investigations are needed to fully understand the contributing factors. The creation of multidisciplinary teams is fundamental for reducing complications, and appropriate reproductive health programs should focus on reducing adolescent pregnancy through better access to education and contraception.

Obstetric outcomes of young women following in-vitro fertilization: a case-control study

Background

Women undergoing in-vitro fertilization (IVF) treatments are at increased risk for maternal and neonatal complications compared to women who conceive spontaneously. Though spontaneous pregnancies of young women and adolescents have an increased risk for adverse maternal and neonatal outcomes, pregnancy outcomes of this age group, following IVF treatment have been scarcely reported. The aim of this study was to report maternal and neonatal outcomes of young women who conceived following IVF compared to women in the same age group with spontaneous conception.

Methods

We performed a multicenter case–control study. The study group included women aged 17–25 years who conceived by IVF with an ongoing singleton pregnancy. For the purpose of the study, a control group matched (1:2 ratio) for maternal age at delivery and parity was constructed. Demographic, medical history, pregnancy related characteristics and maternal and neonatal outcomes were compared between groups. Finally, factors associated with spontaneous vaginal delivery were assessed for the entire cohort using a univariate and multivariate logistic regression model.

Results

Between 2005 and 2021, we identified 80 women aged 19–25 years who conceived by IVF. A control group of 160 women was matched to the study group by age and parity. The unmatched maternal characteristics and pregnancy associated complications were similar among the groups. However, the IVF group had a significantly higher rate of induction of labor (48.1% vs. 26.6%, p = 0.001), meconium-stained amniotic fluid (27.6% vs. 14.1%, p = 0.025), prolonged second stage of labor (26.0% vs. 7.3%, p = 0.001) and operative vaginal delivery (22.5% vs.12.5%, p = 0.048).

Neonatal outcomes were for the most part comparable; nevertheless, we found a higher rate of neonates with an umbilical artery pH < 7.1 in the IVF group (9.8% vs. 0.0%, respectively; p = 0.022).

A logistic regression analysis for spontaneous vaginal delivery (vs. cesarean or operative vaginal deliveries) found that spontaneous onset of labor (vs. induction of labor) (OR = 2.08; 95% CI = 1.07–4.05, p = 0.03) was positively associated with spontaneous vaginal delivery while prolonged second stage of labor (OR = 0.35; 95% CI = 0.13–0.95, p = 0.04) was negatively associated with this parameter.

Conclusion

Young women who conceive by in-vitro fertilization are expected to reach favorable pregnancy outcomes, comparable to women who conceived spontaneously.
