Racial/Ethnic Differences in Unwanted Pregnancy: Moderation by Sexual Orientation

Understanding women from ethnic minorities' perspectives about contraception in the UK: a qualitative study using a participatory action research approach with community research link workers

BACKGROUND

Contraception has revolutionised women's health, enabling planned pregnancies and improved outcomes for mothers and babies. However, disparities exist in rates of unintended pregnancies and contraceptive uptake among ethnic groups. The reasons for this are poorly understood.

OBJECTIVE

To understand women from ethnic minorities' perspectives about contraception.

METHODS

Our qualitative study used a participatory action research approach, utilising community research link workers. Public engagement was embedded in the study's conception. We used focus groups and interviews to elicit perspectives, then analysed the data using thematic analysis. The study participants were women who self-identified as being from an ethnic minority group in Sheffield, UK.

RESULTS

Thirty-six women participated in four focus groups and five interviews. Thematic analysis revealed four themes: (1) The role of contraception in a woman's life, (2) External influencers, (3) Cultural and religious considerations and (4) Everyone is different (individuality). Contraceptive needs should be considered holistically, rather than with a siloed, targeted approach. 'External influencers', such as partners, family and communities, determine how contraception is accessed and experienced. 'Cultural considerations', such as personal, sociocultural and religious factors specific to women from ethnic minorities, influence contraceptive choice.

CONCLUSIONS

This study provides a transcultural perspective of the issues at play when a woman from an ethnic minority makes a decision about contraception. Practitioners and health providers must be culturally competent and tailor consultations and services to the individual.

Family building and pregnancy experiences of cisgender sexual minority women

BACKGROUND

Although 10% to 20% of cisgender women aged 18 to 40 years have a sexual minority identity (eg, bisexual, lesbian, and queer), there is limited research on the family building and pregnancy experiences of sexual minority cisgender women. Improving our understanding of the family building and pregnancy experiences of cisgender sexual minority women is critical for improving the perinatal health of this population.

OBJECTIVE

This study aimed to compare the mode of family building, past pregnancy experiences, and future pregnancy intentions among cisgender sexual minority women by sexual orientation.

STUDY DESIGN

This is an observational study which was conducted using cross-sectional data collected in 2019 from a national sample of 1369 cisgender sexual minority women aged 18 to 45 years.

RESULTS

Most participants (n=794, 58%) endorsed multiple sexual orientations, most commonly queer (n=641, 47%), lesbian (n=640, 47%), and/or bisexual (n=583, 43%). There were 243 (18%) cisgender sexual minority women who were parents. Pregnancy was used by 74% (181/243) of women to build their families. Among participants who used pregnancy, 60% (108/181) became pregnant through sexual activity with another parent of the child, whereas 27% (64/243) of women used donor sperm. An additional 10% (n=24) became parents through second-parent adoption, 10% (n=25) through adoption, and 14% (n=35) through step-parenting. Bisexual women more often used sexual activity to become parents (61/100, 61%) compared with queer (40/89, 45%) and lesbian women (40/130, 31%). In contrast, lesbian (50/130, 39%) and queer (25/89, 27%) women more often used donor sperm to become parents compared with bisexual women (11/100, 11%). Among the 266 (19%) cisgender sexual minority women who had ever been pregnant, there were 545 pregnancies (mean, 2.05 pregnancies per woman). Among those pregnancies, 59% (n=327) resulted in live birth, 23% (n=126) resulted in miscarriage, 15% (n=83) resulted in abortion, and 2% (n=9) resulted in ectopic pregnancy. A quarter of women had future pregnancy intentions, with no differences by sexual orientation. Overall, few participants (16%) reported that all of their healthcare providers were aware of their sexual orientation.

CONCLUSION

Cisgender sexual minority women primarily built their families through pregnancy and a quarter have future pregnancy desires. In addition, there were important differences in family building methods used by sexual orientation. Providers should be aware of the pregnancy and family-building patterns, plans, and needs of cisgender sexual minority women.

Sequencing of Births by Wantedness: Implications for Changes in Mid-Life Health Among Aging NLSY79 Women

OBJECTIVES

As life course frameworks highlight and gerontological studies confirm, the health implications of early birth timing (e.g., adolescent births) and unplanned births (e.g., unwanted or mistimed births) extend years after those births into mid and later life. Yet past research often overlooks the considerable diversity in sequencing and timing of unplanned births even within the same individual (e.g., having both wanted and unwanted births), which are likely fundamental for women's long-term health trajectories. We develop a holistic understanding of birth timing and wantedness to provide insight into when and how childbearing histories matter for aging women's health.

METHODS

We use sequence analysis with hierarchical cluster method and estimate regression models using the 1979 National Longitudinal Survey of Youth (N = 3,231) to examine how timing and patterning of births by wantedness are associated with changes in physical and mental health from ages 40 to 50.

RESULTS

We identify 7 clusters of childbearing sequences. Of those 7 clusters, respondents with sequences characterized by wanted births in their 20s and 30s had the smallest declines in health in mid-life, whereas respondents with sequences with mainly unwanted births at any age or with mainly mistimed births beginning in adolescence had the greatest health declines. Adjusting for social and economic variables accounted for some, but not all, health differences across childbearing clusters.

DISCUSSION

This project demonstrates the need for comprehensive life course perspectives on long-term health implications of birth wantedness and timing, recognizing diversity within and between individuals.

Sexual Orientation-Related Nondiscrimination Laws and Maternal Hypertension Among Black and White U.S. Women

Background: Black women and sexual minority women are more likely to report adverse maternal health. Little research has investigated maternal health disparities at the intersection of race/ethnicity and sexual orientation or the mechanisms that contribute to these disparities. Materials and Methods: We analyzed data from the National Longitudinal Study of Adolescent to Adult Health. Our sample was restricted to Black and White women who had at least one live birth and were followed-up in Wave V of the data (n = 3,396). We used multivariable logistic regression to analyze the associations between race, sexual orientation identity, and a four-item state-level index of sexual orientation-related nondiscrimination laws. Results: We found that higher numbers of state-level sexual orientation-related nondiscrimination laws were associated with lower risk of maternal hypertension among U.S. women overall (odds ratio [OR] = 0.82, 95% confidence interval [CI] 0.73-0.93), and Black women had a higher risk of maternal hypertension relative to White women (OR = 1.32, 95% CI 1.00-1.79). Interactions between race, sexual orientation identity, and sexual orientation-related policies show that, regardless of sexual orientation identity, sexual orientation-related nondiscrimination laws were associated with a lower risk of maternal hypertension among White mothers (OR = 0.80, 95% CI 0.70-0.92). However, among Black women, these laws were associated with a lower risk of maternal hypertension among lesbian and bisexual women (OR = 0.18, 95% CI 0.05-0.68) only. Conclusions: Laws that prevent discrimination related to sexual orientation in various societal domains may play an important role in improving maternal health outcomes among White women in general and Black lesbian and bisexual women in particular.

Mothers' Sexual Identity and Children's Health

Sexual minority women face a plethora of structural, socioeconomic, and interpersonal disadvantages and stressors. Research has established negative associations between women's sexual minority identities and both their own health and their infants' birth outcomes. Yet a separate body of scholarship has documented similarities in the development and well-being of children living with same-sex couples relative to those living with similarly situated different-sex couples. This study sought to reconcile these literatures by examining the association between maternal sexual identity and child health at ages 5-18 using a US sample from the full population of children of sexual minority women, including those who identify as mostly heterosexual, bisexual, or lesbian, regardless of partner sex or gender. Analyses using data from the National Longitudinal Study of Adolescent to Adult Health (N=8,978) followed women longitudinally and examined several measures of their children's health, including general health and specific developmental and physical health conditions. Analyses found that children of mostly heterosexual and bisexual women experienced health disadvantages relative to children of heterosexual women, whereas the few children of lesbian women in our sample evidenced a mixture of advantages and disadvantages. These findings underscore that to understand sexual orientation disparities and the intergenerational transmission of health, it is important to incorporate broad measurement of sexual orientation that can capture variation in family forms and in sexual minority identities.

Breastfeeding Initiation and Continuation Among Sexual Minority Women

OBJECTIVES

Identify disparities in breastfeeding initiation and continuation among sexual minority women (SMW) and determine if known risk factors explain any observed disparities.

METHODS

We used data from the 2006 to 2017 National Survey of Family Growth female pregnancy questionnaire. We measured sexual orientation using self-reported sexual identity and histories of same-sex sexual experiences reported by women (heterosexual-WSM [women who only reported sex with men]; heterosexual-WSW [women who reported sex with women]; bisexual, and lesbian. In total, we had 18,696 births that occurred within the last 10 years and used logistic and multinomial regression models to assess sexual orientation disparities in breastfeeding initiation and duration that clustered on women to account for potential multiple births to a woman.

RESULTS

Compared to heterosexual-WSM, infants born to lesbian-identified women had decreased odds of ever being breastfed (OR 0.55, 95% CI 0.30, 0.99) and a decreased relative risk of being breastfed more than 6 months (RRR 0.46, 95% CI 0.22, 0.97). Infants of heterosexual-WSW had an increased odds of ever breastfeeding (OR 1.40, 95% CI 1.12, 1.74) and increased relative risk of breastfeeding more than 6 months (RRR 1.32, 95% CI 1.02, 1.69).

CONCLUSIONS

Our results show that infants born to lesbian-identified women were less likely to be breastfed than those born to their heterosexual counterparts, even after adjusting for several factors associated with breastfeeding behaviors. We found no differences in breastfeeding between bisexual women and heterosexual-WSM. Understanding and addressing the barriers sexual minority women face for breastfeeding is critical for ensuring maternal and child health equity.

Disparities in smoking during pregnancy by sexual orientation and race-ethnicity

The intersection between sexual orientation and race-ethnicity is emerging as an important dynamic for health. Prior research indicates that sexual orientation can have very different health implications for White, Black, and Latina individuals and that these patterns are unpredictable. Here we use U.S. data from the National Survey of Family Growth (2006-2019, n = 15,163 pregnancies) to examine how an important health indicator - smoking during pregnancy - is shaped jointly by sexual orientation and race-ethnicity. Smoking during pregnancy was more common among sexual minority women (both bisexual-identified and heterosexual-identified who expressed same-gender attraction/behavior), compared to heterosexual women. Second, the association between sexual orientation and smoking during pregnancy differed by race-ethnicity: sexual minority status was more strongly associated with smoking among Latina women, compared to White women. Finally, the subgroup with the highest rates of smoking during pregnancy was bisexual White women. These findings indicate that smoking rates among pregnant sexual minority women warrant attention (regardless of race-ethnicity), particularly as births within this group are rising. It is important to address structural factors that may create more stress for sexual minority women, since smoking is often a response to stress. These findings also highlight the role of heterogeneity: low smoking rates among pregnant Latina women mask within-group disparities.

Multiple marginalisation and unintended pregnancy among racial/ethnic and sexual minority college women

BACKGROUND

Both sexual minority and racial/ethnic minority women are at increased risk of unintended pregnancy compared to their heterosexual and non-Hispanic white peers, respectively. A recent study suggests the presence of negative interaction between sexual orientation and race/ethnicity, although it was not explicitly assessed.

OBJECTIVES

To characterise the burden of unintended pregnancy across groups defined by intersecting sexual orientation and race/ethnicity and to explore for potential intersectional interaction between social identities.

METHODS

We analysed cross-sectional survey data from the National College Health Assessment collected between Fall 2015 and Spring 2018. The relative risk (RR) of unintended pregnancy among college-attending women aged 18-25 was estimated using multivariable log-binomial regression (n = 177 592). We estimated multiplicative- and additive-scale (relative risk due to interaction, RERI) interaction between race/ethnicity and sexual orientation on the risk of unintended pregnancy; 95% confidence intervals (CI) were estimated using 500 bootstrap replicates.

RESULTS

Unintended pregnancy was rare across all intersecting identity groups (≤1.5%). Compared to heterosexual non-Hispanic white women, all groups of sexual minorities and/or racial/ethnic minorities had a higher risk of unintended pregnancy. This was consistent within strata of sexual orientation and race/ethnicity. We did not find strong evidence of additive-scale interaction between sexual orientation and race/ethnicity (RERI -0.19, 95% CI -0.67, 0.28), but we did find negative multiplicative-scale interaction (interaction RR 0.76, 95% CI 0.59, 0.96).

CONCLUSIONS

These findings illustrate that interactions, which are typically used to quantify intersectional effects, are scale-dependent. This has implications regarding how risk estimates for multiply marginalised groups are interpreted. More broadly, our findings suggest the need to move beyond multiple jeopardy approaches to quantitative intersectional research and consider the upstream factors that may uniquely shape the health status of groups at the nexus of particular social identities.

Sexual Identity and Birth Outcomes: A Focus on the Moderating Role of Race-ethnicity

Race-ethnic disparities in birth outcomes are well established, and new research suggests that there may also be important sexual identity disparities in birth weight and preterm birth. This study uses the National Longitudinal Study of Adolescent to Adult Health and is the first to examine disparities in birth outcomes at the intersection of race-ethnicity and sexual identity. We use ordinary least sqaures and logistic regression models with live births (n = 10,318) as the unit of analysis clustered on mother ID (n = 5,105), allowing us to adjust for preconception and pregnancy-specific perinatal risk factors as well as neighborhood characteristics. Results show a striking reversal in the effect of lesbian or bisexual identity on birth outcomes across race-ethnicities: For white women, a bisexual or lesbian identity is associated with better birth outcomes than their white heterosexual counterparts, but for Black and Latina women, it is associated with worse birth outcomes than their heterosexual peers.
