Social Determinants of Health and Adverse Outcomes in Adolescent Pregnancies

The association between adolescent childbearing and adverse maternal and birth outcomes has been well documented. Adverse adolescent pregnancy outcomes are associated with substantial risk of long-term morbidities for the young mother and their newborns. Multiple levels of social disadvantage have been related to adverse pregnancy outcomes among adolescent mothers. Patterns of cumulative social adversity define the most marginalized group of adolescents at the highest risk of experiencing adverse maternal and birth outcomes. Using a social determinants of health (SDOH) framework, we present an overview of the current scientific evidence on the influence of these conditions on adolescent pregnancy outcomes. Multiple SDOH such as residence in remote areas, low educational attainment, low socioeconomic status, and lack of family and community support have been linked with increased risk of adverse pregnancy outcomes among adolescents. Based on the PROGRESS-Plus equity framework, this review highlights some SDOH aspects that perinatal health researchers, clinicians, and policy makers should consider in the context of adolescent pregnancies. There is a need to acknowledge the intersectional nature of multiple SDOH when formulating clinical and societal interventions to address the needs of the most marginalized adolescent in this critical period of life.

Social determinants of health and adverse maternal and birth outcomes in adolescent pregnancies: A systematic review and meta-analysis

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.

Teenage pregnancy in the Texas Panhandle

PURPOSE

This study compares rural and small-city teenage and adult pregnancies, with respect to complication rates and pregnancy outcomes.

METHODS

Chart review of Medicaid patients (513 teenage [under 20 years] and 174 adult controls [ages 25-34]) delivered (excluding multiple gestation) in Amarillo, Texas, from January 1999 to April 2001. Demographic data collected included maternal race, gravidity, parity, smoking status, drug usage, presence of antenatally diagnosed sexually transmitted disease(s), county type (rural vs small city) and number of prenatal visits. Outcomes included mode of delivery, primary cesarean section rates, preterm birth (<34 or <37 weeks), birth weight, birth weight <2500 g, preeclampsia, total maternal weight gain, hemoglobin changes after delivery, Apgar scores, and neonatal intensive care unit admissions. Statistical comparisons between groups were made for a number of factors and outcomes (P < .05).

RESULTS

Teenagers did not have a significantly higher frequency of either illicit drug or tobacco usage, but teenagers <17 years had a greater incidence of sexually transmitted diseases (19.8% vs 10.4%, P < .008) and preeclampsia (7.1% vs 2.3%, P < .025, odds ratio 3.2 [1.1 to 9.9]) when compared with adults. The total weight gain was highest for teens < or =17 years (36.4 pounds vs adults: 28.2, P < .001). The primary cesarean section rate was higher in adults (all teens 18.5% vs adults 38.6%, P < 001). County rurality had no impact on any of the observed findings or variables tested.

CONCLUSIONS

Young teenagers have a higher incidence of sexually transmitted diseases and preeclampsia and also gain significantly more weight with pregnancy than young adults. However, the pregnancy outcomes were no different for rural vs small city teens.

Are rural adolescents necessarily at risk of poorer obstetric and birth outcomes?

OBJECTIVE

The purpose of the present study were to describe the sociodemographic and clinical characteristics of adolescent women giving birth at Wagga Wagga Base Hospital, and compare these with those with all adolescents in New South Wales.

DESIGN

An investigative approach.

MAIN OUTCOME MEASURES

Obstetric complications, delivery intervention and adverse infant outcomes.

SETTING

Wagga Wagga Base Hospital.

PARTICIPANTS

One hundred and sixteen adolescents aged 15-19 years.

RESULTS

In relation to obstetric complications and infants with complications, the study sample was found to be representative of New South Wales adolescents. However, for type of delivery there was a higher rate of forceps delivery (12.3% (15) vs 4.7% (415) P = 0.0001), forceps rotation (4.1% (5) vs 0.9% (80) P = 0.004) and fewer normal vaginal deliveries (67.2% (82) vs 80.8% (7108) P = 0.006) at Wagga Wagga Base Hospital.

CONCLUSION

These findings suggest that rural adolescents are at risk of delivery complications and are less likely to have a normal vaginal delivery. More research is required into obstetric and birth outcomes for the rural adolescent population.
