“…Thirty‐one studies published from 11 countries and involving 59,670,142 adolescent mothers (age range: 10‐19 years) were included in the review . The majority of studies were published in the U.S.(n=18) followed by Australia (n=2) and Nigeria (n=2) . The most frequently evaluated SDOH in the individual studies was race while the most commonly reported maternal and birth outcomes were caesarean section and PTB, respectively.…”

Background Adverse outcomes in adolescent pregnancies have been attributed to both biological immaturity and social determinants of health (SDOH). The present systematic review evaluated the evidence on the association between SDOH and adverse maternal and birth outcomes in adolescent mothers. Methods Comprehensive literature searches were conducted to identify observational studies evaluating the relationship between SDOH and adverse adolescent pregnancy outcomes. Study selection, risk of bias appraisal, and data extraction of study characteristics were independently performed by two reviewers. Pooled odds ratios (pOR) with 95% confidence intervals (95% CI) were calculated to assess the association between SDOH and adverse birth outcomes. Results Thirty‐one studies met the inclusion criteria. The most frequently evaluated SDOH was race while the most commonly reported maternal and birth outcomes were caesarean section and preterm birth (PTB), respectively. The risk of bias of included studies was fair on the Newcastle‐Ottawa Scale. Meta‐analyses of retrospective cohort studies showed that, compared to White adolescent mothers, African American teens had increased odds of PTB (pOR 1.67; 95% CI 1.59, 1.75) and low birthweight (pOR 1.53; 95% CI 1.45, 1.62). Rural residence was consistently linked with PTB while low maternal socio‐economic (SES) and illiteracy were found to increase the risk of adolescent maternal mortality and LBW infants. Conclusion Social determinants of health contribute to the risk of adverse pregnancy outcomes in adolescent mothers. African American race, rural residence, inadequate education, and low SES are markers for poor pregnancy outcomes in adolescent mothers. Further research needs to be done to understand the underlying causal pathways to inequalities in adolescent pregnancy outcomes.

The acute effect of smoking on uteroplacental blood flow was studied by the 133Xe method in 12 normotensive and 11 hypertensive pregnant women at term. A standard cigarette caused an acute decrease in intervillous blood flow in the normotensives but normalized within 15 minutes. In the other group, smoking produced a progressive increase in this flow, whose basal presmoking value lower in the hypertensive women. The myometrial blood flow was equal in both groups before smoking but significantly higher in the hypertensive group immediately afterwards. Smoking produced a constant increase in systolic, diastolic and mean arterial blood pressure in the normotensive women. In the other, diastolic and mean arterial blood pressure increased only temporarily, while systolic blood pressure remained unchanged. Heart rate increased in both groups. Repeated decreases in the intervillous blood flow could explain growth retardation of the fetus and some other complications of pregnancy in normotensive smokers. The authors assume that postischemic reactive hyperemia in the uterine vessels caused the increased flow in hypertensive pregnant women after smoking but cannot recommend it as beneficial because of the increased placental transfer of the harmful elements found in tobacco smoke.
