Birth registration policies in the United States and their relevance to sexual and/or gender minority families: Identifying existing strengths and areas of improvement

Gynecologic Care for Sexual and Gender Minority Patients

Sexual and gender minority (SGM) people, including lesbian, gay, bisexual, transgender, and queer individuals, are a diverse population with a wide spectrum of gynecologic needs. Institutionalized cisheteronormativity, stigmatization, lack of provider training, and fear of discrimination contribute to health disparities in this patient population. In this article, we review key topics in the gynecologic care of SGM patients and provide strategies to enable gynecologists to provide SGM people with equitable and inclusive full spectrum reproductive health care.

Mapping the scientific literature on obstetrical and perinatal health among sexual and gender minoritised (SGM) childbearing people and their infants: a scoping review protocol

INTRODUCTION

Sexual and gender minoritised (SGM) populations are disproportionately impacted by multilevel risk factors for obstetrical and perinatal outcomes, including structural (eg, stigma, discrimination, access to care) and individual risk factors (eg, partner violence, poor mental health, substance use). Emerging evidence shows SGM childbearing people have worse obstetrical outcomes and their infants have worse perinatal outcomes, when compared with their cisgender and heterosexual counterparts; this emerging evidence necessitates a comprehensive examination of existing literature on obstetrical and perinatal health among SGM people. The goal of this scoping review is to comprehensively map the extent, range and nature of scientific literature on obstetrical and perinatal physical health outcomes among SGM populations and their infants. We aim to summarise findings from existing literature, potentially informing clinical guidelines on perinatal care, as well as highlighting knowledge gaps and providing directions for future research.

METHODS AND ANALYSIS

We will follow the Joanna Briggs Institute (JBI) scoping review framework and report findings according to the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. We will conduct a broad systematic search in Medline/PubMed, Embase, CINAHL and Web of Science Core Collection. Eligible studies will include peer-reviewed, empirical, English-language publications pertaining to obstetrical and perinatal physical health outcomes of SGM people or their infants. No temporal or geographical limitations will be applied to the search. Studies conducted in all settings will be considered. Records will be managed, screened and extracted by two independent reviewers. Study characteristics, key findings and research gaps will be presented in tables and summarised narratively.

ETHICS AND DISSEMINATION

Ethical approval is not required as primary data will not be collected. The findings of this scoping review will be disseminated through a peer-reviewed journal and conference presentations.

Sexual and/or gender minority parental structures among California births from 2016 to 2020

BACKGROUND

Sexual and/or gender minority people account for roughly 7.1% of the US population, and an estimated one-third are parents. Little is known about sexual and/or gender minority people who become pregnant, despite this population having documented healthcare disparities that may affect pregnancy.

OBJECTIVE

Our objective was to describe parental structures among birth parents and the prepregnancy characteristics of parents giving birth in likely sexual and/or gender minority parental structures from California birth certificates.

STUDY DESIGN

We conducted a population-based study using birth certificate data from all live births in California from 2016 through 2020 (n=2,257,974). The state amended its birth certificate in 2016 to enable the recording of more diverse parental roles. Now, parents on birth certificates are classified as "parent giving birth" and "parent not giving birth" and people in either role can identify as "mother," "father," or "parent." We examined all potential combinations of parenting roles, and grouped parental structures of "mother-mother" and those designating a "father" as the "parent giving birth" into likely sexual and/or gender minority groups. We assessed the distribution of prepregnancy characteristics across parental structure groups ("mother-father," "sexual and/or gender minority," "mother only," "unclassified," and "missing both parental roles").

RESULTS

Sexual and/or gender minority parents accounted for 6802 (0.3%) of live births in California over the 5-year study period. The most common sexual and/or gender minority parental structures were "mother-mother" (n=4310; 63% of the group) and "father-father" (n=1486; 22% of the group). Compared with "parents giving birth" in the "mother-father" structure (n=2,055,038; 91%), a higher proportion of "parents giving birth" in the "sexual and/or gender minority" group were aged ≥35 years, White, college-educated, and had commercial health insurance. In addition, a higher proportion had a high prepregnancy body mass index. Although likely underreported overall, the proportion of those who used assisted reproductive technology was much higher in the "sexual and/or gender minority" group (1.4%) than in the "mother-father" group (0.05%). Cigarette smoking in the 3 months before pregnancy was similar in both groups.

CONCLUSION

Changes to the California birth certificate have revealed a multiplicity of parental structures. Our findings suggest that sexual and/or gender minority parents differ from other parental structures and from the general sexual and/or gender minority population and warrant further research.

Sexual and/or gender minority disparities in obstetrical and birth outcomes

BACKGROUND

Many sexual and/or gender minority individuals build families through pregnancy and childbirth, but it is unknown whether they experience different clinical outcomes than those who are not sexual and/or gender minority individuals.

OBJECTIVE

To evaluate obstetrical and birth outcomes comparing couples who are likely sexual and/or gender minority patients compared with those who are not likely to be sexual and/or gender minority patients.

STUDY DESIGN

We performed a population-based cohort study of live birth hospitalizations during 2016 to 2019 linked to birth certificates in California. California changed its birth certificate in 2016 to include gender-neutral fields such as "parent giving birth" and "parent not giving birth," with options for each role to specify "mother," "father," or "parent." We classified birthing patients in mother-mother partnerships and those who identified as a father in any partnership as likely sexual and/or gender minority and classified birthing patients in mother-father partnerships as likely not sexual and/or gender minority. We used multivariable modified Poisson regression models to estimate the risk ratios for associations between likely sexual and/or gender minority parental structures and outcomes. The models were adjusted for sociodemographic factors, comorbidities, and multifetal gestation selected by causal diagrams. We replicated the analyses after excluding multifetal gestations.

RESULTS

In the final birthing patient sample, 1,483,119 were mothers with father partners, 2572 were mothers with mother partners, and 498 were fathers with any partner. Compared with birthing patients in mother-father partnerships, birthing patients in mother-mother partnerships experienced significantly higher rates of multifetal gestation (adjusted risk ratio, 3.9; 95% confidence interval, 3.4-4.4), labor induction (adjusted risk ratio, 1.2; 95% confidence interval, 1.1-1.3), postpartum hemorrhage (adjusted risk ratio, 1.4; 95% confidence interval, 1.3-1.6), severe morbidity (adjusted risk ratio, 1.4; 95% confidence interval, 1.2-1.8), and nontransfusion severe morbidity (adjusted risk ratio, 1.4; 95% confidence interval, 1.1-1.9). Severe morbidity was identified following the Centers for Disease Control and Prevention "severe maternal morbidity" index. Gestational diabetes mellitus, hypertensive disorders of pregnancy, cesarean delivery, preterm birth (<37 weeks' gestation), low birthweight (<2500 g), and low Apgar score (<7 at 5 minutes) did not significantly differ in the multivariable analyses. No outcomes significantly differed between father birthing patients in any partnership and birthing patients in mother-father partnerships in either crude or multivariable analyses, though the risk of multifetal gestation was nonsignificantly higher (adjusted risk ratio, 1.5; 95% confidence interval, 0.9-2.7). The adjusted risk ratios for the outcomes were similar after restriction to singleton gestations.

CONCLUSION

Birthing mothers with mother partners experienced disparities in several obstetrical and birth outcomes independent of sociodemographic factors, comorbidities, and multifetal gestation. Birthing fathers in any partnership were not at a significantly elevated risk of any adverse obstetrical or birth outcome considered in this study.
