“…In this study, the adverse fetal outcome were the main outcome variables. It was defined as the occurrence of one or more of the following fetal outcomes: LBW (delivery of a live infant whose birth weight was less than 2500 g), 37 , 38 preterm (babies born alive before 37 weeks of pregnancy are completed), 39 low Apgar score at 5 minutes (less than 7), neonatal death (death of a live birth within 28 days), 12 stillbirth (fetal death at or after 28 weeks gestation). 29 The wealth index was generated using 26 variables.…”

Background: According to the World Health Organization, teenage pregnancies are high-risk due to increased risks of fetal and infant morbidity and mortality. This study compares adverse fetal outcomes between teen and adult pregnant women from rural Eastern Ethiopia. Methods: Institutional-based cross-sectional study was conducted among women visiting maternity units from surrounding rural areas. A total of 481 teenagers (13-19 years old) and 481 adults (20-34 years old) women with a singleton pregnancy were included in the study. Two hospitals and 3 health centers were selected in Eastern Hararghe Zone, Eastern Ethiopia. Comparative analysis was carried out using the log-binomial regression model to identify factors associated with adverse fetal outcomes in both categories. The results are reported in adjusted prevalence ratios with 95% confidence intervals. Results: High proportion of adverse fetal outcome was observed among teenage women than adult (34.9% vs 21%). Statistically significant difference ( P < .05) in the proportion of low birth weight (21.1% vs 9.3%), preterm birth (18.7% vs 10.6%), APGAR score at 5th minute (9.3% vs 4%) were found in teenagers compared to adult women. Antenatal care attendance (APR = 0.44; 95% CI: 0.23, 0.86); eclampsia (APR = 1.96; 95% CI: 1.26, 3.06); pre-eclampsia (APR = 1.73; 95% CI: 1.12, 2.67); and wealth index (rich) (APR = 0.55; 95% CI: 0.32, 0.94) were significantly associated with adverse fetal outcomes among the teenage women. Whereas intimate partner violence (APR = 2.22; 95% CI: 1.26, 3.90); preeclampsia (APR = 3.05; 95% CI: 1.61, 5.69); antepartum hemorrhage (APR = 2.77; 95% CI: 1.73, 4.46); and hyperemesis gravderm (APR = 1.75; 95% CI: 1.09, 2.79) were significantly associated with adverse fatal outcomes among the adult women. Conclusion: teenage pregnancy is associated with a high rate of adverse fetal outcomes. Early identification and treatment of problems during antenatal follow-up should be the mainstay to avert the massive adverse fetal effects.

Background and Aims Early‐term birth between 37 and 38 weeks of gestation increases the risk of mortality and morbidity. This study investigated the status and impact of early‐term birth among neonates born by cesarean section in Japan. Methods All singleton live births that had data of gestational age at birth available in the Japan Environment and Children's Study (JECS), a nationwide birth cohort study launched in 2011, were eligible for this study. Neonates born by cesarean delivery at term without indications for early delivery were included to examine the association between early‐term birth and respiratory distress at birth. The gestational age at birth was categorized as 37 weeks 0 day to 38 weeks 6 days (early‐term), 39 weeks 0 day to 40 weeks 6 day (full‐term), and 41 weeks 0 day to 41 weeks 6 days (late‐term). Respiratory distress at birth included respiratory distress syndrome, transient tachypnea, and difficulty in breathing after birth. Univariable and multivariable analyses were performed using logistic regression models with a two‐tailed significance level of 5%. All statistical analyses were performed using SAS, version 9.4, for Windows (SAS Institute, Cary, NC). Results In total, 32 078 of 100 011 (32.1%) neonates had early‐term birth. At 37 gestational weeks, 49.7% of the deliveries were via cesarean section, and half of the cesarean deliveries were due to a previous cesarean section. Among the 10 051 neonates born by elective cesarean delivery at term, neonates with early‐term births were more likely to have respiratory distress at birth (adjusted odds ratio: 4.19; 95% confidence interval, 1.70, 10.34) than those born at full term. Conclusions Early‐term birth is associated with a high risk of respiratory distress in births involving cesarean delivery without indication for early delivery. There is a need for guidelines for early delivery considering adverse effects of early‐term births.

“…85,86 Factors such as nulliparous women, multiple pregnancies, advanced maternal age (≥40 years), history of PTD, and maternal medical disorders have also been identified as main predictive factors for the risk of preterm babies. 87 Studies also indicated that obese women (BMI≥30kg/m 2 ) 41 ; underweight women (BMI≤18.5kg/m 2 ), 40 some ethnic minorities, vegetarians and vegans to be at risk of MN deficiencies 74 which made the women more prone to adverse pregnancy outcomes. Studies reported also that markers of maternal pre-pregnancy status like short stature, low and high BMI are linked to increased risks of PTD and SGA.…”

Micronutrients are vitamins, minerals and trace elements that are used in minute doses as cofactors, antioxidants and modulators of gene transcription homeostasis. MMNs may have a role in averting or treating adverse pregnancy outcomes and maternal complications. In 2016, WHO suggested the use of iron-folic acid (IFA) rather than multiple micronutrients (MMNs) during pregnancy owing to some feared adverse outcomes like perinatal mortalities. However, this effect is debatable as such complications could be also due to genetic or environmental factors. Therefore, this appraisal should provide appropriate information and guidance to health workers, scholars and policymakers. This review includes large sample-sized studies with a special focus on developing countries like Ethiopia. The articles were selected using systematic searching with Boolean operators, advanced search techniques, snowballing and search limits. Mendeley was used as a reference management tool where the source of databases and references were PubMed, AJOL, Google Scholar, IRIS, Summon, DOAJ, Cochrane Library, Oxford Medicine Online, WHO reproductive health libraries majorly from the Hinari program. Articles from BMC, American Society for Nutrition, Lancet, Elsevier, John Wiley and Sons LTD, PLoS One, Springer and Nature Publishing Groups were also used. The results showed that there are no variations in adverse effects between MMNs and IFA. Moreover, MMNs are valuable in anemic pregnant women with lower preconception weight as it increases maternal weight and reduces low birth weight and anemia more than IFA. Therefore, MMNs may have greater health benefits than IFA for the offspring by minimizing fetal complications and the cost of their treatment, resulting from the MMN deficiency state.
