LGBTQ Parents Fare Worse Giving Birth

LGBTQ Parents Fare Worse Giving Birth

Members of the LGBTQ community who give birth appear to have a greater risk of hypertensive disorders of pregnancy and postpartum hemorrhage, according to new research presented at the annual meeting sponsored by the Society for Maternal-Fetal Medicine.

“Our study found that birthing patients in likely sexual and gender minority partnerships experienced disparities in clinical outcomes,” Stephanie Leonard, PhD, an epidemiology and biostatistics instructor at the Stanford (Calif.) University division of maternal-fetal medicine and obstetrics, told attendees at the meeting. The disparities are likely because of various social determinants and possibly higher use of assisted reproductive technology (ART). The findings establish “how these are significant disparities that have been largely overlooked and set the groundwork for doing further research on maybe ways that we can improve the inclusivity of obstetric care.”

Jenny Mei, MD, a maternal-fetal medicine fellow at the University of California, Los Angeles, who attended the presentation but was not involved in the research, said the findings were “overall unfortunate but not surprising given the existing studies looking at LGBTQ patients and their poorer health outcomes, largely due to lack of access to health care and discrimination in the health care setting.”

Leonard described the societal, interpersonal, and individual factors that can contribute to health disparities among gender and sexual minority patients.

“At the societal level, there are expectations of what it means to be pregnant, to give birth, and to be a parent. At the community level, there’s the clinical care environment, and at the interpersonal level, there’s an obstetrician’s relationship with the patient,” Leonard said. “At the individual level, most notably is minority stress, the biological effects of the chronic experience of discrimination.”

It has historically been difficult to collect data on this patient population, but a change in the design of the California birth certificate made it possible to gather more data than previously possible. The updated California birth certificate, issued in 2016, allows the parent not giving birth to check off whether they are the child’s mother, father, parent, or “not specified” instead of defaulting to “father.” In addition, the parent giving birth can select mother, father, parent or not specified instead of being “mother” by default.

The researchers classified sexual and gender minority (SGM) partnerships as those in which the parent giving birth was identified as the father and those where both parents were identified as mothers. Non-SGM minority partnerships were those in which the birthing parent was identified as the mother and the nonbirthing parent was identified as the father.

The population-based cohort study included data from all live birth hospitalizations from 2016-2019 in California, whose annual births represent one in eight babies born each year in the United States. The population of SGM patients different significantly from the non-SGM population in nearly every demographic and clinical factor except rates of pre-existing diabetes. For example, 42% of the SGM birthing patients were age 35 or older, compared with 23% of the non-SGM patients.

SGM patients were more likely to be born in the United States, were more likely to be White, and were less likely to be Asian or Hispanic. SGM patients had higher education levels and were more likely to have private insurance. They were also more likely to be nulliparous and have chronic hypertension. Average body mass index for SGM patients was 33 kg/m2, compared with 30 for non-SGM patients. SGM patients were also much more likely to have multifetal gestation: 7.1% of SGM patients versus 1.5% of non-SGM patients.

In terms of clinical outcomes, 14% of SGM patients had hypertensive disorders of pregnancy, compared with 8% of non-SGM patients. Before adjustment for potential confounders, SGM patients were also twice as likely to have postpartum hemorrhage (8% vs. 4% in non-SGM patients) and postterm birth at 42-44 weeks (0.6% vs 0.3% in non-SGM patients).

“Having increased postterm birth is a matter of declining induction of labor, as it is recommended to have an induction by 41 weeks of gestation in general,” Mei said in an interview. “It is also possible this patient cohort faces more barriers in access to care and possible discrimination as sexual/gender minority patients.”

Rates of severe preeclampsia, induction of labor, cesarean delivery, preterm birth, low birth weight, and a low Apgar score were also higher among SGM patients, but these associations were no longer significant after adjustment for age, education, payment method, parity, prepregnancy weight, comorbidities, and multifetal gestation. The difference in hypertensive disorders of pregnancy, postpartum hemorrhage, and postterm birth remained statistically significant after adjustment.

Past research has shown that only about a third of cisgender female same-sex marriages used ART, so the disparities cannot be completely explained by ART use, Leonard said.

“I think the main drivers are structural disparities,” Leonard said. “Every obstetric clinic is focused in a way that’s about mother-father, and many people who don’t feel like they fit into that paradigm feel excluded and disengage with health care.”

Elliott Main, MD, a clinical professor of obstetrics and gynecology at Stanford University and coauthor of the study noted that discrimination and stigma likely play a substantial role in the disparities.

“Sexual and/or gender minority people face this discrimination at structural and interpersonal levels on a regular basis, which can lead to chronic stress and its harmful physical effects as well as lower-quality health care,” Main said in an interview.

Another coauthor, Juno Obedin-Maliver, MD, an assistant professor of obstetrics and gynecology at Stanford, emphasized how much room for improvement exists in care for SGM obstetric patients.

“We hope that this study brings needed attention to the disparities in perinatal health experienced by sexual and/or gender minority people,” Obedin-Maliver said. “There is much we can do to better understand the family building goals of sexual and/or gender minority people and help those to be achieved with healthy outcomes for parents and their children.”

One limitation of the study is that it’s possible to misclassify individuals using the birth certificate data, and not everyone may be comfortable selecting the box that accurately represents their identity, particularly if they aren’t “out” or fear discrimination or stigma, so the population may underrepresent the actual numbers of sexual and gender minority individuals giving birth. Mei added that it would be helpful to see data on neonatal ICU admissions and use of ART.

It’s difficult to say how generalizable the findings are, Mei said. “It is possible the findings would be more exaggerated in the rest of the country outside of California, if we assume there is potentially lower health access and more stigma.” The fact that California offers different gender options for the birthing and nonbirthing parent is, by itself, an indication of a potentially more accepting social environment than might be found in other states.

”The take-home message is that this patient population is higher risk, likely partially due to baseline increased risk factors, such as older maternal age and likely use of ART, and partially due to possible lack of health access and stigma,” Mei said. “Health care providers should be notably cognizant of these increased risks, particularly in the psychosocial context and make efforts to reduce those burdens as much as possible.”

The research was funded by the Stanford Maternal and Child Health Research Institute. Obedin-Maliver has consulted for Sage Therapeutics, Ibis Reproductive Health, and Hims. Mei and the other authors had no disclosures.
