Comparative analysis of perinatal outcomes and birth defects amongst adolescent and older Ugandan mothers: evidence from a hospital-based surveillance database

Survival patterns of neonates born to adolescent mothers and the effect of pregnancy intentions and marital status on newborn survival in Kenya, Uganda, and Tanzania, 2014-2016

Background

Adolescent pregnancy and associated neonatal mortality are major global health challenges. In low-income settings where 90% of the 21 million global adolescent pregnancies occur, half are unintended and a fifth experience unsafe abortion. In Kenya, Uganda, and Tanzania, the survival patterns of neonates born to adolescents are unclear.

Objectives

To assess survival patterns among neonates born to adolescents and the effect of pregnancy intentions and marital status on survival in Kenya, Uganda, and Tanzania.

Methods

Cross-sectional data from demographic and health surveys in Kenya, Uganda, and Tanzania 2014–2016 were used. Kaplan-Meier estimates investigated patterns of neonatal survival among adolescent mothers, aged 15–19 years, compared to mothers aged 20–29 years. Cox proportional hazards regression determined the hazard ratios (HR) for the predictors of neonatal survival.

Results

About 50% of adolescent pregnancies were unintended and neonatal death rate was twice as high than older mothers (26.6 versus 12.0 deaths/1000 live births). The median survival time was two days for adolescent-born babies and four days among older mothers. The hazard of death for all adolescent-born neonates was about twofold that of 20–29 years-old-mothers, HR 1.80 (95% CI 1.22–2.63). Among married adolescents with unintended newborn pregnancies, the HR was 4-folds higher than corresponding older mothers, HR 4.08 (95% CI 1.62–10.31). Among married, primiparous adolescents with unintended pregnancies, the HR was six times higher than corresponding older mothers.

Conclusion

Our findings reveal how unintended pregnancies and deaths of neonates born to adolescents contribute substantially to preventable neonatal deaths in East Africa. Full implementation of existing adolescent health policies and utilization of contraceptives should be ensured. Partnership with youths and novel efforts that address sociocultural norms to reduce adolescent pregnancies or marriage should be supported. Regulations requiring adolescents’ obstetric care conducted by only skilled personnel should be introduced and implemented.

Neonatal Outcome Associated With Maternal COVID-19 Infection in Adolescent Patients

Background

Coronavirus disease 2019 (COVID-19) infection during pregnancy has been associated with high rates of preeclampsia, stillbirth, and preterm birth. Adolescent pregnancy has also been associated with various adverse maternal and neonatal outcomes, including preeclampsia, stillbirth, preterm birth, congenital anomalies, and low birth weight. Therefore, this study aimed to determine whether COVID-19 infection associated with adolescent pregnancy represents an additional risk factor.

Methods

We performed a study that included 17 adolescent COVID-19- positive patients, who delivered in the Department of Obstetrics and Gynecology of University Emergency Hospital, Bucharest, between 01.04.2020 and 15.04.2022, and a control group of 17 patients who were COVID-19-negative and delivered in the same period in the same unit. In the control group, additional risk factors that could affect neonatal outcomes were excluded. The COVID-19 infection was confirmed using a polymerase chain reaction (PCR) test. The analysis of neonatal outcomes included preterm birth, low birth weight, stillbirth, congenital anomalies, and Apgar score calculated at one minute.

Results

The data from this study showed that COVID-19 infection does not influence the newborn's weight or Apgar score in adolescent patients. Also, in our study, COVID-19 infection was not statistically significant according to preterm delivery in adolescents.

Conclusion

Adolescent pregnancy represents an important health problem associated with a high risk of maternal and neonatal complications. However, COVID-19 infection does not influence neonatal outcomes in this population.

Adverse obstetric and neonatal outcomes of adolescent pregnancies in Africa: a scoping review

BACKGROUND

Adolescent pregnancy is a public health issue with well-defined causes and health risks with social and economic implications. Aim of this review was to examine adverse pregnancy outcomes and risk factors associated with adolescent pregnancy in Africa.

METHOD

PubMed Central, Science Direct and JSTOR were the main databases for the literature review. Other online sources and experts were consulted for relevant studies. In all, 11,574 records were identified and 122 were considered as full-text studies for evaluation after thorough screening and removal of duplicates. Finally, 53 studies were included in this review for thematic synthesis.

RESULTS

The 53 studies sampled 263,580 pregnant women, including 46,202 adolescents (< 20 years) and 217,378 adults (> 20 years). Adolescent pregnancy was associated with higher risks of adverse pregnancy outcomes. Factors of poor pregnancy outcomes included low socioeconomic and educational status, poor utilization of antenatal care, risky lifestyles such as alcohol consumption, and unattractive health care factors. Maternal health care utilization was identified as an important factor to improve pregnancy outcomes among adolescents in Africa.

CONCLUSION

To prevent adolescent pregnancy, stakeholders need to help lower socioeconomic inequalities, poor utilization of antenatal care, alcohol consumption, and improve adolescents' health care and their educational status. Issues such as child marriage, abortion, poor health care infrastructure and non-adolescent friendly health facilities need to be addressed.

Maternal and Neonatal Outcomes of Adolescent Pregnancy: A Narrative Review

Adolescent pregnancy is the pregnancy of girls aged 10-19 years, leading to many maternal and neonatal adverse effects. These pregnancies have been a global concern for many decades and yet are still prevailing. This article has reviewed the significant determinants of adolescent pregnancy and various maternal adverse effects, including preeclampsia, preterm premature rupture of the membrane (PPROM), maternal anemia, sexually transmitted diseases, postpartum depression, and maternal deaths, and adverse neonatal outcomes, including low birth weight (LBW), prematurity, stillbirths, early neonatal demise, and low Apgar score. Various pathophysiologic events that lead to such adverse consequences have been briefly discussed in the article and how such occurrences can be overcome. This article has also emphasized the need to implement various modalities such as sex education, availability of contraceptives, and bringing community-level awareness to lower the prevalence of adolescent pregnancy.

ECD - Pregnancy outcomes of a birth cohort. Are adolescent mothers really at more risk?

This sub-study within the JAKIDS longitudinal cohort study compares medical and psychosocial outcomes of pregnancy in younger adolescent mothers (<16 years), older adolescent mothers (16-19 years) and adult mothers (>19 years) in Jamaica. Participants were recruited from July to September 2011 and included 9521 mother-infant dyads; mean maternal age 26.0 years (SD 6.8). Adolescent mothers represented 19.1% (n = 1822) of the sample - 1704 older adolescent mothers (17.9%) and 118 younger adolescent mothers (1.2%). Participants completed interviewer-administered questionnaires regarding their sexual and reproductive health history, feelings about the current pregnancy, and presence of anxious and depressive symptoms. Data on delivery and perinatal and neonatal outcomes were extracted from hospital charts. Younger adolescent mothers were more likely to deliver preterm (p < 0.001) and low birth weight infants (p < 0.001) than older adolescent and adult mothers. Younger adolescent mothers had lower levels of antenatal anxiety regarding the pregnancy and its outcome (p < 0.001) while prevalence of elevated depressive symptoms antenatally (EPDS ≥11) was similar across age groups. Older adolescent mothers with significant depressive symptoms had increased odds of preterm delivery. These findings call for close antenatal monitoring of younger adolescent mothers and highlight the need for psychological services for all mothers.
