The healthy migrant effect and predictors of perinatal depression

Social Determinants of Health Among Pregnant Hispanic Women and Associated Psychological Outcomes

BACKGROUND

There has been a concerning surge in maternal mortality among Hispanic women in recent years. Compromised mental health is present in nearly half of all maternal deaths, and risk factors include poor social support and depression.

OBJECTIVE

Among Hispanic women who were born in the USA versus those not born in the USA, we sought to describe and compare social determinants of health and maternal psychological outcomes.

METHODS

Hispanic pregnant women (n = 579) were recruited from two clinics in Tampa, FL, and completed various questionnaires related to social determinants of health, depression, stress, and social support.

STATISTICAL ANALYSIS

Descriptive statistics, t-tests, and chi-square analyses were used to compare relationships between maternal nativity and subsequent psychosocial outcomes. Pearson correlations were used to explore associations between variables.

RESULTS

Hispanic pregnant women who were not born in the USA had lower incomes (χ2 = 5.68, p = 0.018, df = 1), were more likely to be unemployed (χ2 = 8.12, p = 0.004, df = 1), and were more likely to be married (χ2 = 4.79, p = 0.029, df = 1) when compared with those born in the USA. Those not born in the USA reported lower social support (t = 3.92, p<0.001), specifically the tangible (t = 4.18, p < 0.001) and emotional support subscales (t = 4.4, p<0.001). When compared with those born in the USA, foreign-born Hispanic women reported less stress (t = 3.23, p = 0.001) and depression (t = 3.3, p = 0.002).

CONCLUSION

Pregnant Hispanic women not born in the USA are at increased risk for suboptimal social determinants of health, including less social support. US-born women were more stressed and depressed and had higher BMIs.

The global burden of perinatal common mental health disorders and substance use among migrant women: a systematic review and meta-analysis

BACKGROUND

There are one billion migrants globally, of whom 82 million are forced migrants. Pregnant migrants face pre-migration stressors such as conflict, transit stressors including poverty, and post-migration stressors including navigating the immigration system; these stressors can make them vulnerable to mental illness. We aimed to assess the global prevalence of and risk factors for perinatal mental health disorders or substance use among women who are migrants.

METHODS

In this systematic review and meta-analysis, we searched OVID MEDLINE, Embase, PsycINFO, CENTRAL, Global Health, Scopus, and Web of Science for studies published from database inception until July 8, 2022. Cohort, cross-sectional, and interventional studies with prevalence data for any mental illness in pregnancy or the postnatal period (ie, up to a year after delivery) or substance use in pregnancy were included. The primary outcome was the prevalence of perinatal common mental health disorders among women who are migrants, globally. Data for study quality and risk factors were also extracted. A random-effects meta-analysis was used to calculate pooled prevalence estimates, when appropriate. Sensitivity analyses were conducted according to study quality, sample representativeness, and method of outcome assessment. Risk factor data were synthesised narratively. This study is registered with PROSPERO, CRD42021226291.

FINDINGS

18 650 studies were retrieved, of which 135 studies comprising data from 621 995 participants met the inclusion criteria. 123 (91%) of 135 studies were conducted in high-income host countries. Five (4%) of 135 studies were interventional, 40 (30%) were cohort, and 90 (66%) were cross-sectional. The most common regions of origin of participants were South America, the Middle East, and north Africa. Only 26 studies presented disaggregated data for forced migrants or economic migrants. The pooled prevalence of perinatal depressive disorders was 24·2% (range 0·5-95·5%; I² 98·8%; τ² 0·01) among all women who are migrants, 32·5% (1·5-81·6; 98·7%; 0·01) among forced migrants, and 13·7% (4·7-35·1; 91·5%; 0·01) among economic migrants (p<0·001). The pooled prevalence of perinatal anxiety disorders was 19·6% (range 1·2-53·1; I² 96·8%; τ² 0·01) among all migrants. The pooled prevalence of perinatal post-traumatic stress disorder (PTSD) among all migrant women was 8·9% (range 3·2-33·3; I² 97·4%; τ² 0·18). The pooled prevalence of perinatal PTSD among forced migrants was 17·1% (range 6·5-44·3; I² 96·6%; τ² 0·32). Key risk factors for perinatal depression were being a recently arrived immigrant (ie, approximately within the past year), having poor social support, and having a poor relationship with one's partner.

INTERPRETATION

One in four women who are migrants and who are pregnant or post partum experience perinatal depression, one in five perinatal anxiety, and one in 11 perinatal PTSD. The burden of perinatal mental illness appears higher among women who are forced migrants compared with women who are economic migrants. To our knowledge, we have provided the first pooled estimate of perinatal depression and PTSD among women who are forced migrants. Interpreting the prevalence estimate should be observed with caution due to the very wide range found within the included studies. Additionally, 66% of studies were cross-sectional representing low quality evidence. These findings highlight the need for community-based routine perinatal mental health screening for migrant communities, and access to interventions that are culturally sensitive, particularly for forced migrants who might experience a higher burden of disease than economic migrants.

Psychosocial and behavioral health indicators among immigrant and non-immigrant recent mothers

BACKGROUND

Perinatal risk factors can vary by immigration status. We examined psychosocial and behavioral perinatal health indicators according to immigration status and immigrant characteristics.

METHODS

We conducted a population-based cross-sectional study of 33,754 immigrant and 172,342 non-immigrant childbearing women residents in Manitoba, Canada, aged 15-55 years, who had a live birth and available data from the universal newborn screen completed within 2 weeks postpartum, between January 2000 and December 2017. Immigration characteristics were from the Canadian federal government immigration database. Logistic regressions models were used to obtain Odds Ratios (OR) with 95% confidence intervals (CI) for the associations between immigration characteristics and perinatal health indicators, such as social isolation, relationship distress, partner violence, depression, alcohol, smoking, substance use, and late initiation of prenatal care.

RESULTS

More immigrant women reported being socially isolated (12.3%) than non-immigrants (3.0%) (Adjusted Odds Ratio (aOR): 6.95, 95% CI: 6.57 to 7.36) but exhibited lower odds of depression, relationship distress, partner violence, smoking, alcohol, substance use, and late initiation of prenatal care. In analyses restricted to immigrants, recent immigrants (< 5 years) had higher odds of being socially isolated (aOR: 9.04, 95% CI: 7.48 to 10.94) and late initiation of prenatal care (aOR: 1.50, 95% CI: 1.07 to 2.12) compared to long-term immigrants (10 years or more) but lower odds of relationship distress, depression, alcohol, smoking and substance use. Refugee status was positively associated with relationship distress, depression, and late initiation of prenatal care. Secondary immigrants, whose last country of permanent residence differed from their country of birth, had lower odds of social isolation, relationship distress, and smoking than primary migrants. There were also differences by maternal region of birth.

CONCLUSION

Immigrant childbearing women had a higher prevalence of social isolation but a lower prevalence of other psychosocial and behavioral perinatal health indicators than non-immigrants. Health care providers may consider the observed heterogeneity in risk to tailor care approaches for immigrant subgroups at higher risk, such as refugees, recent immigrants, and those from certain world regions.

Understanding the Healthy Immigrant Effect in the Context of Mental Health Challenges: A Systematic Critical Review

The "Healthy Immigrant Effect" (HIE) suggests that immigrants have a health advantage over the domestic-born which vanishes with increased length of residency. Most HIE research focuses on physical health, with less attention given to mental health (MH). This systematic review of 58 MH studies examines whether there is a MH advantage among immigrants and explores changes in immigrants' MH, besides critically assessing the use of HIE theory. Inconsistent evidence was detected regarding the presence of MH advantage, whereas consistent, convincing evidence was revealed for a decline in immigrants' MH over years. Although the HIE theory can help reveal MH disparities, this theory alone does not explain the reasons for these disparities nor inform about potential avenues to improve immigrants' MH. A paradigm shift is needed to incorporate other potential theoretical concepts/frameworks, including the "Health Inequalities Action" framework, for a broader understanding of MH issues and to inform effective, culturally-sensitive interventions.

Comparing the Different Manifestations of Postpartum Mental Disorders by Origin, among Immigrants and Native-Born in Israel According to Different Mental Scales

We conducted a prospective study, aimed to study whether the prevalence of mental disorders after birth differs by country of origin. Parturient mothers of Ethiopian origin, Former-USSR (FSU) origin, or nonimmigrant, native-Israeli origin (n = 974, all Jewish) were recruited in hospitals in Israel and were followed 6–8 weeks and one year after birth. General linear models were used to study the associations between origin and mental health, comparing Ethiopian and FSU origin with native-Israeli. Ethiopian and FSU mothers were more likely to report on somatic symptoms, compared with native-Israeli women. Ethiopian origin was negatively and significantly associated with anxiety in all three interviews (β = −1.281, β = −0.678 and β = −1.072, respectively; p < 0.05 in all). FSU origin was negatively associated with depression after birth (β = −0.709, p = 0.036), and negatively associated with anxiety after birth and one-year postpartum (β = −0.494, and β = −0.630, respectively). Stressful life events were significantly associated with all mental disorders in the three time points of interviews. Our findings suggest that immigrants tend to express higher mental distress with somatic symptoms. Additional tools are needed for mental distress screening among immigrants.

The antenatal risk questionnaire-revised: Development, use and test-retest reliability in a community sample of pregnant women in Australia

BACKGROUND

Routine psychosocial assessment during pregnancy and the first postnatal year is a public health strategy that prioritises early identification of known risk factors for poor perinatal mental health. We aimed to report on the development and use of the Antenatal Risk Questionnaire-Revised (ANRQ-R), contribute normative data for a community sample of pregnant women and examine its test-retest reliability.

METHODS

The ANRQ-R was developed in consultation with an expert advisory group. Women completed the ANRQ-R with their midwife at their first antenatal appointment. Test-retest analysis was restricted to women who consented to follow-up and completed a repeat ANRQ-R within four weeks.

RESULTS

7183 women completed the ANRQ-R (total score M = 12.05, Mdn=10; range =5-49). There were some statistically significant differences in total score across maternal age group (χ²=69.75, p<.001), country of birth (χ²=144.01, p<.001) and socioeconomic quintiles (χ²=20.13, p<.001), however the effect sizes of all differences were either small or not clinically significant. Test-retest reliability for the ANRQ-R total score was good (N = 1670; ICC=0.77). Item-level test-retest reliabilities were moderate to good (ICC range=0.65-0.80; kappa coefficient range=0.31-0.74).

LIMITATIONS

The study was conducted at a single site. Although there was significant diversity in terms of maternal age and country of birth, the majority of participants were partnered and resided in socio-economically advantaged areas, limiting the generalisability of results.

CONCLUSIONS

This study contributes significant normative data for the ANRQ-R and offers valuable insights for clinicians and researchers working with particular sub-groups of the perinatal population. Additional psychometric examination of the ANRQ-R, including its concurrent and predictive validity, is required.

Facilitators and barriers to accessing mental health care services and social supports among perinatal refugee women: a qualitative systematic review protocol

OBJECTIVE

The objective of this qualitative review is to identify, critically appraise, and synthesize evidence describing facilitators and barriers to perinatal refugee women's access to mental health care services and social supports.

INTRODUCTION

Perinatal refugee women are a vulnerable population and at risk of mental health illness. Understanding facilitators and barriers will provide a better understanding of their experiences to inform health care practices, programs, and policies.

INCLUSION CRITERIA

This qualitative review will consider all peer-reviewed qualitative studies and gray literature on perinatal refugee women's experiences of accessing mental health care services and social supports. Non-English articles and studies that do not explicitly state participants' migration status as refugees will be excluded.

METHODS

This review will adhere to the JBI methodology for conducting qualitative systematic reviews. Key information sources searched will be CINAHL, PsycINFO, PubMed, Web of Science, and the Social Sciences Citation Index. Search terms will be modified for each information source. Sources of evidence published in English between January 2011 and the present will be assessed for inclusion. Two independent reviewers will screen titles and abstracts using the inclusion criteria for study selection. The reviewers will critically appraise methodological quality and rigor. Data will be extracted on facilitators and barriers among perinatal refugee women accessing mental health care services and social supports. Synthesis will involve aggregation of these findings to generate a set of statements based on their meaning similarity.

Psychosocial stratification of antenatal indicators to guide population-based programs in perinatal depression

BACKGROUND

There is increasing awareness that perinatal psychosocial adversity experienced by mothers, children, and their families, may influence health and well-being across the life course. To maximise the impact of population-based interventions for optimising perinatal wellbeing, health services can utilise empirical methods to identify subgroups at highest risk of poor outcomes relative to the overall population.

METHODS

This study sought to identify sub-groups using latent class analysis within a population of mothers in Sydney, Australia, based on their differing experience of self-reported indicators of psychosocial adversity. This study sought to identify sub-groups using latent class analysis within a population of mothers in Sydney, Australia, based on their differing experience of self-reported indicators of psychosocial adversity. Subgroup differences in antenatal and postnatal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale.

RESULTS

Latent class analysis identified four distinct subgroups within the cohort, who were distinguished empirically on the basis of their native language, current smoking status, previous involvement with Family-and-Community Services (FaCS), history of child abuse, presence of a supportive partner, and a history of intimate partner psychological violence. One group consisted of socially supported 'local' women who speak English as their primary language (Group L), another of socially supported 'migrant' women who speak a language other than English as their primary language (Group M), another of socially stressed 'local' women who speak English as their primary language (Group Ls), and socially stressed 'migrant' women who speak a language other than English as their primary language (Group Ms.). Compared to local and not socially stressed residents (L group), the odds of antenatal depression were nearly three times higher for the socially stressed groups (Ls OR: 2.87 95%CI 2.10-3.94) and nearly nine times more in the Ms. group (Ms OR: 8.78, 95%CI 5.13-15.03). Antenatal symptoms of depression were also higher in the not socially stressed migrant group (M OR: 1.70 95%CI 1.47-1.97) compared to non-migrants. In the postnatal period, Group M was 1.5 times more likely, while the Ms. group was over five times more likely to experience suboptimal mental health compared to Group L (OR 1.50, 95%CI 1.22-1.84; and OR 5.28, 95%CI 2.63-10.63, for M and Ms. respectively).

CONCLUSIONS

The application of empirical subgrouping analysis permits an informed approach to targeted interventions and resource allocation for optimising perinatal maternal wellbeing.
