Intergenerational risk and resilience pathways from discrimination and acculturative stress to infant mental health

Preconception and prenatal stress impact fetal and infant development, and women of color are disproportionately exposed to sociocultural stressors like discrimination and acculturative stress. However, few studies examine links between mothers ’ exposure to these stressors and offspring mental health, or possible mitigating factors. Using linear regression, we tested associations between prenatally assessed maternal acculturative stress and discrimination on infant negative emotionality among 113 Latinx/Hispanic, Asian American, Black, and Multiethnic mothers and their children. Additionally, we tested interactions between stressors and potential pre- and postnatal resilience-promoting factors: community cohesion, social support, communalism, and parenting self-efficacy. Discrimination and acculturative stress were related to more infant negative emotionality at approximately 12 months old ( M = 12.6, SD = .75). In contrast, maternal report of parenting self-efficacy when infants were 6 months old was related to lower levels of infant negative emotionality. Further, higher levels of parenting self-efficacy mitigated the relation between acculturative stress and negative emotionality. Preconception and prenatal exposure to sociocultural stress may be a risk factor for poor offspring mental health. Maternal and child health researchers, policymakers, and practitioners should prioritize further understanding these relations, reducing exposure to sociocultural stressors, and promoting resilience.

Racial and ethnic health disparities are persistent and costly, carrying massive negative social, health, and fiscal consequences (Ayanian, 2015;National Center for Health Statistics, 2021;Weinstein et al., 2017). The U.S. Department of Health and Human Services' ambitious Healthy People 2020 initiative aimed to eliminate health disparities by 2020, but this goal was far from achieved in many areas. In fact, some racial/ethnic disparities even worsened over time, including rates of adolescent depression and suicide (National Center for Health Statistics, 2016aStatistics, , 2016b. Further, higher rates of both internalizing and externalizing symptoms are found among children and adolescents of color compared to White populations (Alegria et al., 2010(Alegria et al., , 2015Bogart et al., 2013;Price et al., 2013). These inequities warrant widespread concern and attention and become ever more pressing as children of color move into the "diverse majority," rather than the minority, of the U.S. youth population (as of 2020; Society for Research in Child Development, 2021).
The seminal Integrative Model for the Study of Developmental Competencies in Minority Children (hereafter referred to as the Integrative Model) introduced a new framework for studying development among youth of color (García Coll et al., 1996;Perez-Brena et al., 2018). A central tenet of this model is the need to recognize and study unique forms of oppression as important contributors to developmental outcomes for racially/ethnically diverse youth (Causadias & Umaña-Taylor, 2018;García Coll et al., 1996). Similarly, there are growing calls from health disparities researchers to situate all discussion of racial/ethnic disparity within the context of structural racism (Boyd, Lindo, et al., 2020;García & Sharif, 2015;Marks et al., 2020). In other words, it cannot be overstressed that race in and of itself is not a risk factor for persisting racial/ethnic health disparities; rather it is the cumulative impact of multiple forms of racial oppression, including inequitable access and treatment across economic opportunity, intergenerational wealth, and virtually all public systems (including child welfare, criminal justice, health, and education), all of which work together synergistically to persistently undermine the health of people of color (Bailey et al., 2017(Bailey et al., , 2021Boyd, Lindo, et al., 2020;García & Sharif, 2015;Gee & Ford, 2011; National Scientific Council on the Developing Child, 2020). This understanding is supported by a large body of research (Alegria et al., 2015;Koh et al., 2011;Williams et al., 2016). However, less explicitly studied and discussed are the ways in which these challenges likely transmit health risk biologically across generations through mechanisms related to the developmental origins of health and disease (DOHaD; Conradt et al., 2020).

Developmental origins of health and disease and child mental health
The DOHaD model suggests that adversity in prenatal and early life influences biological systems and impacts physical and mental health across the lifespan (Barker, 2007;Gluckman et al., 2016;Hentges et al., 2019). This model includes the idea of fetal programing, wherein fetal development is impacted by changes to the intrauterine environment as a result of maternal context, including biological and psychological adversity. DOHaD and fetal programing hypotheses are supported by research linking prenatal maternal stress, mood, and adversity to the fetal environment and to adverse birth outcomes, disrupted motor and cognitive development, long-term health risks such as obesity and cardiometabolic disorders, and mental health challenges including depression, anxiety, attention deficit hyperactivity disorder, conduct disorder, and more general internalizing and externalizing symptoms (Davis & Sandman, 2010Essau et al., 2018;Glynn et al., 2018;Graignic-Philippe et al., 2014;Hicks et al., 2019;Irwin et al., 2020;Lupien et al., 2009;Park et al., 2014;Van den Bergh et al., 2017). Importantly, studies attempting to understand psychiatric risk earlier in life have identified negative emotionality in infants, which includes frustration, fear, discomfort, sadness, and low soothability (Rothbart, 2007), as an indicator of future mental health challenges (Bush et al., 2017;Crawford et al., 2011;Luecken et al., 2015).

Sociocultural stressors
Although there has been substantial growth in evidence supporting DOHaD and links between maternal stress and child development, there has been relatively little focus in this area on sociocultural stressors that disproportionately impact communities of color (Conradt et al., 2020;D'Anna-Hernandez et al., 2015;Liu & Glynn, 2021). In fact, there is a dearth of research that examines preconception or prenatal influences of offspring behavioral development among diverse and/or low-income populations, despite the greater risk of exposure to stress within these communities (Bush et al., 2017;Conradt et al., 2020;Demers et al., 2021). Therefore, guided by both DOHaD and the Integrative Model, we examine two prevalent stressors among populations of color in the current studydiscrimination and acculturative stressas potential prenatal stressors related to offspring mental health.
Discrimination refers to unjust, unequal, or biased attitudes or behavior towards an individual because of their race, sex, class, or other characteristics. Importantly, women of color often hold multiple marginalized and minoritized identities (including gender and race/ethnicity) and are therefore at higher risk of experiencing multiple forms of discrimination (Earnshaw et al., 2013;Watson et al., 2016). Acculturative stress describes the stress of adapting to new cultures, including new dominant behaviors, customs, schools of thought, and values (Berry, 1997;D'Anna-Hernandez et al., 2015;Sam & Berry, 2010). Acculturative stress is often discussed in the context of immigrant populations, however, it has also been described as a phenomenon facing all members of historically nondominant cultural groups within the US (Walker, 2007). Both discrimination and acculturative stress have been linked to maternal mental health (Canady et al., 2008;D'Anna-Hernandez et al., 2015;Ertel et al., 2012). Discrimination has also been associated with physiological change during pregnancy and adverse birth outcomes such as preterm birth and low birthweight (Alhusen et al., 2016;Chaney et al., 2019;Dominguez et al., 2008;Giurgescu et al., 2011;Hilmert et al., 2014). Although there is very little existing research examining the impact of preconception or prenatal maternal exposure to discrimination or acculturative stress on offspring health, one recent study did find an association between prenatal discrimination and negative emotionality and inhibition/separation problems among infant offspring (Rosenthal et al., 2018). These findings support existing concerns regarding intergenerational impact of sociocultural stressors and highlight the urgent need for further study in this area.

Resilience-promoting factors
In addition to calling for recognition of unique cultural contexts and oppressive systems facing populations of color, García Coll's Integrative Model emphasizes the importance of identifying factors that contribute to positive development (García Coll et al., 1996). In the current study, we are particularly interested in factors contributing to resilience, or adaptation and wellness in the presence of adversity and risk (Masten & Coatsworth, 1998;Rutter, 1987). Resilience processes can be (a) compensatory/ promotive, when a resource exerts a main, positive effect on an adaptive outcome in the presence of a risk factor; or (b) protective, when a resource reduces the relation between a risk factor and maladaptive outcome, as reflected in an interaction effect of the risk factor and resource on outcome (Fergus & Zimmerman, 2005;Zimmerman et al., 2013;Zolkoski & Bullock, 2012). Few studies have addressed specifically the pre-or postnatal resilience-promoting factors that contribute to infant mental health. Therefore, for this exploratory investigation, we informed our selection of resilience-promoting factors with both theory and evidence. Following the Integrative Model's emphasis on different ecologies that surround a developing child (e.g., family and community), as well as culturally specific influences (i.e., communalism) (Cabrera, 2013;García Coll et al., 2000;Perez-Brena et al., 2018;Umaña-Taylor et al., 2015), we chose to investigate three domains of resilience-promoting factors with existing empirical support outside of infant mental healthsocial capital, communalism and parenting self-efficacy.
Community cohesion and social support encompass two facets of social capital that have been linked to reduced levels of stress and other mental health problems (Hong et al., 2014; National Academies of Sciences Engineering and Medicine, 2019; Saleem et al., 2018;Svensson & Elntib, 2021;Yamada et al., 2021). Social support refers to one's network of social connections that provide both emotional and tangible forms of support, while community cohesion is defined as the presence of mutual trust and solidarity within one's local community (Sampson et al., 1997). Although both community cohesion and social support have been related to better birth outcomes, albeit inconsistently (Feldman et al., 2000;Hetherington et al., 2015;National Academies of Sciences Engineering and Medicine, 2019;Schetter, 2011), less research has examined the relation between prenatal maternal social capital and child outcomes.
Communalism is a cultural orientation towards interdependence (and thought to stand in contrast to the Eurocentric value of independence) that emphasizes social bonds, social duties, and the importance of collective well-being, both outside and within one's family (i.e., familism) (Abdou et al., 2010;Schwartz et al., 2010). Communalism has been highlighted by researchers as a potential culturally specific resilience-promoting asset for racially/ethnically diverse populations, including Black, Latinx/Hispanic, and Asian American groups (Moemeka, 1998;Schwartz et al., 2010;Woods-Jaeger et al., 2021). However, evidence has been mixed in its level of support for this hypothesis (Abdou et al., 2010;Gaylord-Harden & Cunningham, 2009;Harris & Molock, 2000), and some scholars have suggested that higher levels of communalism may sensitize one to the presence of stressors such as discrimination (Goldston et al., 2008;Perez-Brena et al., 2018).
Finally, the concept of parenting self-efficacy is grounded in social cognitive theory (Bandura, 1986(Bandura, , 1997 and describes a caregiver's confidence in their ability to parent successfully. Self-efficacy is informed both by one's individual beliefs as well as their observations and experiences in their environment (Bloomfield & Kendall, 2012;Raikes & Thompson, 2005). Parenting self-efficacy has been linked to better psychological health and adjustment among both children and parents (Albanese et al., 2019;Wittkowski et al., 2017), but there is a lack of research on parenting self-efficacy in the context of sociocultural stressors.

Current study
Drawing on the Integrative Model's framework for studying unique determinants of risk, as well as resilience among youth of color (García Coll et al., 1996), and DoHAD's emphases on early life antecedents of health and development (Barker, 2007;Gluckman et al., 2016), the current study prospectively examines intergenerational risk and resilience pathways to infant mental health. Specifically, we examine risk pathways by testing relations between sociocultural stressors assessed prenatally (discrimination and acculturative stress) and infant offspring negative emotionality. We test for both compensatory/promotive and protective resilience pathways by assessing main and interactive associations (with sociocultural stressors) of community cohesion, social support, communalism, and parenting self-efficacy with negative emotionality. Given the dearth of existing research on maternal prenatal sociocultural stress, infant temperament, and resiliencepromoting factors, this was largely an exploratory study. We did anticipate sociocultural stress to be associated with infant negative emotionality, and that resilience-promoting factors may buffer these relations.

Participants
Study participants were a subsample of 113 mothers and their children (53% male) who identified as a race or ethnicity other than White, drawn from a larger longitudinal study beginning in pregnancy. Our sample consisted of 69% of mothers selfidentifying as Latinx/Hispanic, 15% as Asian American, 11.5% as Multiethnic, and 4.4% as Black. 1 Participants were recruited from Southern California medical clinics during their first trimester of pregnancy. Inclusion criteria included singleton intrauterine pregnancy, being 18 years of age or older, English-speaking, absence of tobacco, alcohol, or drug use during pregnancy and medical conditions impacting endocrine, cardiovascular, hepatic, or renal functioning. Participant characteristics are reported in Table 1. On average, mothers were 28 years old (SD = 5.65, range = 18.05-41.57) with a median household income of $52,158. Approximately a third of participants (31.9%) were born outside the U.S. Similarly, about a third of the sample spoke a language other than English in their household (35.4%). There was also a wide distribution of maternal education level, with 30.1% completing high school or less, 49.6% having some college, an associate degree, or a vocational or certificate program degree. Lastly, 20.3% of the sample had completed college or graduate school.

Procedure
All study procedures were approved by the responsible Human Subjects Review Board. Study subjects participated in a series of pre-and postnatal study visits that included questionnaires and structured interviews to collect information on maternal and infant demographics, mood, health, risk, resilience, and infant development. The current study sample includes all participants who completed the 12-month postpartum study visit. Supplementary Table 1 provides an overview of data collection.

Measures
Gestational age at birth (GAB) was determined using the last menstrual period and an ultrasound prior to 20 weeks gestational age, in line with guidelines of the American College of Obstetricians and Gynecologists (American College of Obstetricians and Gynecologists Committee on Obstretic Practice, 2017). How one identifies their own race/ethnicity is not straightforward, and we acknowledge the ways in which imposed categorizations/terminology can, either advertently or inadvertently, feel inaccurate and/or cause harm. Therefore, we aim to define which terms we use to denote our participants' race/ethnicity, while acknowledging they are not universally standard or identified with by various cultural groups within the U.S. In our study, Black is used to refer people of African ancestry, Asian American to refer to people of Asian descent, Latinx/Hispanic/Hispanic to refer to participants from Spanish-speaking countries and/or Latin American descent, and Multiethnic to refer to participants belonging to multiple racial/ethnic groups (American Psychological Association, 2019; Noe-Bustamante et al., 2020; U of SC Aiken, n.d.). We also report participants' self-reported verbatim race/ethnicity: three participants stated they were African American, six Asian, one Asian American, one Asian Japanese,

Sociocultural stressors
Acculturative stress was measured at a 25-week prenatal visit with the Societal, Attitudinal, Environmental, and Familial Acculturative Stress Scale short version (SAFE; Mena et al., 1987). Subjects were asked to rate the stressfulness of 24 items on a 5-point Likert scale (e.g., "It bothers me that family members I am close to do not understand my new values" and "It bothers me when people pressure me to assimilate (or blend in)"), with higher scores indicating greater acculturative stress. The SAFE has demonstrated strong reliability and been used with different immigrant and later generation populations (Ahmed et al., 2011;D'Anna-Hernandez et al., 2015;Mena et al., 1987;Shattell et al., 2008). Internal reliability in the current sample was 0.88.
Discrimination was assessed at the 25-week prenatal visit with Williams' Major and Everyday Discrimination Scales (Williams et al., 2007). The Major Experiences of Discrimination scale asks participants if they have experienced unfair treatment as it pertains to nine different situations (e.g., ever been unfairly fired, stopped by the police, and so forth). The number of situations participants endorse are summed for a total score. The Everyday Discrimination Scale asks participants how often in their day-to-day life they have experienced discriminatory treatment in 10 contexts, such as being treated with less courtesy than others or followed around in stores (never, once, two or three times, four or more times). The number of times reported is summed for a total score. Both scales have demonstrated construct validity (Taylor et al., 2004).

Resilience-promoting factors
Community cohesion was assessed at the 25-week prenatal visit with 12 statements from the Social Ties Scale (Cutrona et al., 2000) referring to different types of community support which participants indicated as either true or false (e.g., neighbors get together to deal with community problems, neighbors help and look out for one another). Endorsed items were summed for a total score. This scale has demonstrated adequate reliability in previous research (Cutrona et al., 2000) and had an alpha value of 0.86 in the current study.
Social support also was measured at the 25-week visit with the Medical Outcomes Study Social Support Survey (MOS-SS; Sherbourne & Stewart, 1991). The MOS-SS consists of 19 items asking about tangible support, positive social interaction, affection, and emotional/informational support. This scale has been used extensively and demonstrates strong reliability Sherbourne & Stewart, 1991). The current study uses a standardized total score, and internal reliability was .98.
Communalism was assessed at the 35-week prenatal visit with a 28-item scale developed by Abdou et al. (2010) from two wellestablished scales assessing familism and communalism. Participants responded to items such as "I owe it to my parents to do well in life" or "I would take time off from work to visit a sick friend" on a 4-point scale ranging from "strongly disagree" to "strongly agree." Items are summed for a total score. The scale has demonstrated good reliability with pregnant women (Abdou et al., 2010) and had an alpha value of 0.84 in the current study.
Parenting self-efficacy was collected at 6 months postpartum with the Maternal Self-Efficacy in the Nurturing Role Questionnaire (Pedersen et al., 1989). The questionnaire consists of 16 items on a 7-point Likert scale asking mothers' how representative they feel different statements are of their parenting experience. Example items include, "I am concerned that my patience with my baby is limited" and "I trust my feelings and intuitions about taking care of my baby." Items are summed for a total score. This scale has previously demonstrated adequate test-retest reliability and internal consistency (Pedersen et al., 1989;Porter & Hsu, 2003) and had internal reliability of 0.84 in the current study.

Infant temperament
Infant Negative Emotionality at 12 months was assessed with the Infant Behavior Questionnaire (IBQ; Gartstein & Rothbart, 2003), a 191-item measure that has been used extensively in developmental research and demonstrates good reliability and validity (Goldsmith & Campos, 1990;Worobey & Blajda, 1989). In order to reduce maternal reporting bias, questions assess the infant's concrete behaviors in clearly defined situations, for example, "During a peek-a-boo game, how often did the baby smile?" and "How often during the last week did the baby startle to a sudden or loud noise?" Individual item responses can range from 1 "never" to 7 "always." The questionnaire items map onto three primary temperament dimensions: Negative Emotionality, Surgency/ Extraversion and Orienting/Regulation. The Negative Emotionality dimension, the focus of this investigation, is comprised of four subscales: Sadness, Fear, Falling Reactivity, and Distress to Limitations. Internal reliability of this dimension in the current study was 0.92.

Data analyses
Descriptive analyses included examination of sample demographics, data distributions, bivariate associations, and levels of sociocultural stressors and resilience-promoting factors by race/ ethnicity. To select model covariates, we examined demographic variables with prior theoretical or empirical support for association with infant temperament with bivariate correlations, including biological sex at birth, GAB, household income, parental cohabitation, birth order, maternal nativity status, and maternal education. All variables significantly associated (p < .05) with temperament were included in subsequent models. The amount of missing data averaged less than 4% across all variables included in analyses, and Little's MCAR test indicated there was no systematic pattern of missing values (χ 2 (52) = 55.36, p = .35).
Hierarchical linear regression was utilized to first assess the impact of sociocultural stressors on infant negative emotionality above and beyond covariates. Only sociocultural stressors that showed bivariate associations with negative emotionality were included in regression models. Promotive (main) and protective (interaction) effects of resilience-promoting factors were subsequently tested in a third step (community cohesion, social support, communalism, and parenting self-efficacy). The same four models were repeated with each sociocultural stressor.
Lastly, because a number of DoHAD findings have suggested that vulnerabilities to prenatal stress are sex-differentiated (Braithwaite et al., 2017;Clayborne et al., 2021;Glynn & Sandman, 2012;Hicks et al., 2019;McLaughlin et al., 2021;Rosa et al., 2019;Sandman et al., 2013;Sharp et al., 2015), we tested the interaction of stressor X sex in a fourth step. All continuous variables contributing to interaction terms were centered prior to analysis.
Hayes' (2018) PROCESS macro for SPSS was used to plot and probe significant interactions at the 16th and 84th percentiles of the predictor variable (indicating low and high levels of the predictor; Hayes, 2018), and the 16th, 50th, and 84th percentile of the moderator (indicating low, moderate, and high levels of the moderator). The Johnson-Neyman technique was utilized to define regions of significance (Hayes, 2018). Table 2 displays means and bivariate associations of study variables. All sociocultural stressors were positively associated with one another. Among resilience-promoting factors, social support was associated with both community cohesion and communalism. Everyday discrimination and acculturative were related to more negative emotionality, while parenting self-efficacy and GAB were related to less negative emotionality.

Descriptive information
Participants' average levels of sociocultural stressors and resilience-promoting factors are presented by race/ethnicity in Table 3. Although differences across race/ethnicity were not tested statistically, descriptively Black and Multiethnic participants experienced the greatest amount of discrimination on average, while Asian American participants had the highest levels of acculturative stress. Black participants reported the highest average levels of all resilience-promoting factors.

Risk and resilience analyses
Both everyday discrimination and acculturative stress (assessed prenatally) significantly predicted infant negative emotionality after adjusting for GAB (see Step 1 in Tables 4-5 and Figure 1). When entered into the linear regression model with everyday discrimination, parenting self-efficacy had a promotive/main effect on negative emotionality such that higher levels of parenting selfefficacy were associated with less infant negative emotionality (see Table 4, Figure 1a). When entered into the model with acculturative stress, parenting self-efficacy had a significant protective/interaction effect, with moderate and higher levels of parenting selfefficacy buffering the relation between acculturative stress and infant negative emotionality (see Table 5, Figure 1b; Conditional Effects: Low PSE: t = 3.40, p < .001; Moderate PSE: t = 1.21. p = .23; High PSE: t = −0.57, p = .57). The Johnson−Neyman Regions of Significance test indicated the relation between acculturative stress and negative emotionality was no longer statistically significant when level of parenting self-efficacy was above 97.02 (approximately 43rd percentile in the current sample). As parenting self-efficacy levels increased beyond 97, the relation between acculturative stress and negative emotionality continued to decrease in strength. No other resilience factors (community cohesion, social support, or communalism) were found to have significant main or interaction effects on negative emotionality in models with acculturative stress or everyday discrimination (six models in total). These results are provided in the Supplementary Material (see Supplementary Tables 4-7).
Results testing the interaction of sex and sociocultural stressors are reported in the Supplementary Material. The interaction of sex and acculturative stress during pregnancy reached statistical significance in some (see Supplementary Tables 5,7,9), but not all models. Plotting this interaction suggests the association between acculturative stress and negative emotionality may be stronger for girls than boys (see Figure 2).

Discussion
The far reaching effects of mental health disorders in childhood are disproportionately felt by youth of color (Alegria et al., 2010;Marrast et al., 2016), emphasizing the importance of understanding and ultimately intervening with early antecedents and precipitants of childhood mental health challenges. Although it is established that preconception and prenatal stress impacts offspring mental health (Graignic-Philippe et al., 2014;Park et al., 2014;Van den Bergh et al., 2017), to date stressors emphasized by the Integrative Model as critical for understanding development in populations of color, including discrimination and acculturative stress (García Coll et al., 1996), have been understudied in this context. Further, questions remain unanswered about which maternal factors promote infant resilience to preconception and prenatal adversity exposure (Liu & Glynn, 2021). Results of the current study add empirical evidence to these existing research gaps. Specifically, we found that maternal experiences of acculturative stress and everyday discrimination, assessed prenatally, predicted infants' greater negative emotionality at 12 months of age, but that mothers' parenting self-efficacy at 6 months of age counteracted these effects.
Our findings have implications for future study as well as prevention and intervention. Accumulating research has shown that acculturative stress and discrimination are harmful to one's health (Bekteshi & van Hook, 2015;D'Anna-Hernandez et al., 2015;Paradies et al., 2015;Revollo et al., 2011;Williams et al., 2019). Here, we see evidence that they may also be risk factors for mental health of the next generation. Notably we did not find an association between major events of discrimination and infant negative emotionality, consistent with previous research findings that more chronic, everyday discrimination may be more harmful to health and development (Ayalon & Gum, 2011;Bennett et al., 2010;Wheaton et al., 2018). Therefore, the development of, and research on, policies and programs to reduce maternal stress exposure must consider acculturative stress and chronic discrimination.
Because we found associations between parenting self-efficacy and lower levels of infant negative emotionality, and did not find links of the same magnitude for communalism, social support, or community cohesion, our results also indicate the potential of intervention and prevention programs that enhance parenting self-efficacy to promote child emotional health and reduce later mental health challenges. One method for achieving this goal could involve brief parenting support and parenting skill sessions embedded into pediatric well-child visits (Weisleder et al., 2016) or home visiting programs (Granado-Villar et al., 2009) throughout a child's first year of life. There are a number of brief parenting interventions, such as Triple P, that have already been shown to improve parenting self-efficacy (Gilkerson et al., 2020;Tully & Hunt, 2016).
The current study also highlights some priority areas for future research. More studies are needed to replicate and expand the links between prenatal sociocultural stress and infant negative emotionality, including through the study of additional indicators of emotional and cognitive development, and later mental health outcomes. Notably, analyses found some evidence to suggest that the association between acculturative stress and negative emotionality differed by sex. Specifically, in some models, the effect appeared stronger for girls than boys. Future research examining this moderation by sex with larger sample sizes could improve understanding of this potential interaction, but these results do align with those of previous researchers (Braithwaite et al., 2017;Hicks et al., 2019;Sandman et al., 2013). Evidence suggests mechanisms behind these results may include differential HPA axis and placental responses to stress based on fetal sex (Hicks et al., 2019).
Another important observation from this study was the presence of statistically significant associations among all of the sociocultural stressors examinedsuggesting that women of color face multiple co-occurring stressors related to their race/ethnicity and social position in a society built on structural racism (Bailey et al., 2017). For this reason, we did not examine specific types of discrimination, such as sexism and racism, but rather assessed the impact of any form of chronic discrimination on birth outcomes. However, future research that considers distinctive sources of discrimination and other stressors, including structural racism, is necessary.
One possible mediating factor is earlier GAB, which was related to infant negative emotionality in the current study, and has previously been linked to maternal experiences of prenatal discrimination (although we did not see associations with acculturative stress or everyday discrimination; Alhusen et al., 2016;Christian, 2020). Maternal distress stemming from sociocultural stress also could be an intermediary factor; this hypothesis is supported by research findings that discrimination and acculturative stress are linked to depressive symptoms (Canady et al., 2008;D'Anna-Hernandez et al., 2015) and infant temperament (see Supplemental Table S10).
In this study, community cohesion, communalism, and social support did not show statistically significant resilience-promoting effects. However, continuing to test these factors is important because their effectiveness may be dependent on certain contextual factors, such as cultural background or acculturation level. It is important that future research statistically test these differences in larger samples, as it may guide understanding of what forms of resilience and protective factors are more likely accessible within communities of color.
There also are limitations to the current research that are important to note. First, the sample was limited in terms of its Figure 1. Parenting self-efficacy functions as a resilience-promoting factor in the context of prenatally assessed maternal sociocultural stressors (a, everyday discrimination, b, acculturative stress) and infant negative emotionality. Note. Low, moderate, and high represent the 16th, 50th, and 84th percentiles of the predictor and moderator variables. Figure 2. The relation between prenatally assessed acculturative stress and negative emotionality is stronger for girls. Note. Low and high acculturative stress represent the 16th and 84th percentiles. Model adjusts for gestational age at birth. racial/ethnic diversity, with the majority of participants (69%) being Latinx/Hispanic. Although discrimination is a universal experience for all populations of color, these experiences are not distributed equally or uniformly across populations (Lee et al., 2019). Research on larger samples that allows for the statistical testing of these differences, as well as the examination of relations between sociocultural stressors and infant outcomes separately for mothers and infants of various race/ethnicities, could help to elucidate if these stressors are more salient for some populations versus others, and why.
Second, while our conclusion that parenting self-efficacy may have a positive impact on subsequent infant negative emotionality is heightened by distal and sequential separation of the measures (6 and 12 months) it is important to acknowledge that these findings are maternal report and correlational. As such, there is a possibility that parenting self-efficacy may be enhanced when parenting an infant with an easier temperament. However, prior research findings suggest that parenting self-efficacy prospectively predicts infant negative temperament, but not the other way around (Verhage et al., 2013). It is also conceivable that these relations may be influenced by maternal bias, although a recent study of 935 mothers found configural, metric, and scalar invariance between mothers with and without a lifetime history of depression across dimensions of maternal-rated child temperament, leading authors to conclude that maternal report of youth temperament is not biased by maternal mental illness (Olino et al., 2020). The likelihood of bias is also reduced by the IBQ's specific measure design to avoid maternal reporting bias through asking questions about infants' concrete behavior in specific situations. Still, future research that confirms the relation between sociocultural stress, parenting self-efficacy, and infant temperament as measured with independent observers or with behavioral measures would strengthen the validity the current findings. Lastly, this study did not include postnatal measures of discrimination and acculturative stress, thus limiting our understanding of whether preconception or prenatal sociocultural stress has a distinctive impact on infant temperament over and above postnatal sociocultural stress. Future research that includes these measures at both pre-and postnatal timepoints can assist in understanding how timing matters for stress transmission.
Despite this study's limitations, the implications of our findings are clear. In the field of maternal and child health, several truths must be acknowledged. First, women of color face more stressors compared to their White counterparts because of societal systems that marginalize people of color, and second, this stress exposure translates to health risk for offspring, potentially perpetuating health disparities across generations. This recognition is particularly important in the current moment, as we are presently experiencing a unique historical time of societal upheaval and threat against communities of color. The years leading up to 2022 have been marked by rising national rates of White nationalism and White supremacy, racially motivated hate crimes, anti-immigrant rhetoric and policies, and racist police brutality (Boyd, Krieger, et al., 2020;Seaton et al., 2018). The year 2020 was defined by the COVID-19 pandemic, which illuminated and exacerbated economic and health inequities across racial lines and exposed the deeply embedded nature of racism in the U.S (Boyd, Krieger, et al., 2020;Liu & Modir, 2020;Seaton et al., 2018). The consequences of COVID-19 for communities of color, in conjunction with continued police killings of unarmed Black people and the massive protests that followed, has led many cities and organizations across the country to make a long overdue declaration: that racism is a public health crisis (Krieger, 2020). Findings of the current study and others suggest that heightening racism across the country will have a long-lasting impact on maternal and infant health, yet COVID-19 is ironically likely to shift attention away from these areas in the short-term, due to urgent competing health priorities (Jacob et al., 2020).
Therefore, there is a need for research, policy, and practice that pushes for further understanding of relations between prenatal sociocultural stress and infant outcomes, that reduces stress exposure, and that promotes resilience in this context. Having a comprehensive understanding of the role of structural racism in health disparities is critical for anyone engaging in this work, and advocates have called for researcher and practitioner training in topics such as structural competency, cultural humility, structural determinants of disease, defining race as a social and power construct, and institutional inequities as a root cause of injustice (Bailey et al., 2017;Barkley et al., 2013;Cerdeña et al., 2020;Metzl et al., 2018;Metzl & Hansen, 2014). Lastly, while interventions focused on prenatal health and child and family well-being are needed and important, true primary prevention to achieve health equity necessitates the creation of policies and systems that no longer systematically undermine the health of people of color (National Scientific Council on the Developing Child, 2020).
