Homelessness in pregnancy: perinatal outcomes

The Association between Psychosocial Stressors and Gestational Weight Gain: Analysis of the National Pregnancy Risk Assessment Monitoring System (PRAMS) Results from 2012 to 2015

OBJECTIVE

Both psychosocial stress and gestational weight gain are independently associated with adverse maternal and fetal outcomes. Studies of the association between psychosocial stress and gestational weight gain (GWG) have yielded mixed results. The objective of this study was to evaluate the association between psychosocial stress and GWG in a large population-based cohort.

METHODS

Data from the nationally representative Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 7 questionnaire 2012-2015 was utilized. Maternal psychosocial stress was assessed through response to questions designed to examine four domains of psychosocial stress (i.e., traumatic, financial, emotional, partner-related) three months prior to or during pregnancy. GWG was categorized using pre-pregnancy BMI and total GWG into inadequate, adequate, or excessive according to the Institute of Medicine's GWG guidelines. Multinomial logistic regression was used to evaluate the association between psychosocial stressors and adequacy of GWG. Analyses took into account complex survey design.

RESULTS

All respondents who delivered ≥ 37 weeks gestation with GWG information available were included in the analysis (n = 119,183). After adjusting for confounders, patients who reported financial stress were more likely to experience excessive versus adequate GWG (RRR 1.09 [95%CI: 1.02-1.17]). Exposure to any of the stressor groups did not significantly increase the risk of inadequate GWG.

CONCLUSIONS

This large, population-based study revealed that among pregnant people in the US, exposure to financial stress is associated with higher risk of excessive GWG. Understanding the role stress plays in GWG will help to inform initiatives targeting this important aspect of prenatal care.

Homelessness in pregnancy

OBJECTIVES

To evaluate the association, if any, of homelessness or refuge accommodation on delivery and short term perinatal outcomes in an Irish tertiary maternity hospital.

METHODS

A retrospective cohort study of 133 singleton pregnancies in women reporting to be homeless or living in refuge at their booking antenatal appointment between 2013 and 2022. Analysis compared sociodemographic characteristics and perinatal outcomes in this cohort to a reference population of 76,858 women with stable living arrangements.

RESULTS

Women in the homeless/refuge population were statistically more likely to be single (75.2 % vs 39.5 %, p < 0.001), have an unplanned pregnancy (73.7 % vs 27.2 %, p < 0.001), report a history of psychiatric illness (42.9 % vs 22.4 %, p < 0.001), domestic violence (18.8 % vs 0.9 %, p < 0.001) alcohol consumption in pregnancy (3.0 % vs 0.8 %, p < 0.001) or smoking in pregnancy (41.3 % vs 9.7 %, p < 0.001). They were significantly more likely to have a preterm birth (adjusted OR 1.71 (1.01-2.87) p = 0.04). They also had a significantly lower median birth weight compared to the reference population (birthweight 3270 g vs 3420 g, p < 0.001).

CONCLUSION

Women in the homeless and refuge population are more likely to experience poorer perinatal outcomes compared to women with stable living arrangements.

Antenatal Psychiatric Hospitalization: Factors Associated With Newborns' Custody Under Child Protective Services (CPS)

BACKGROUND

Psychiatric illness during pregnancy is associated with adverse obstetric outcomes, but investigations into its impact on parenting capacity are limited. Child Protective Services (CPS) contact disproportionately impacts families marginalized by poverty, mental health disorders, and substance use disorders. Recently, there have been investigations into the significance of psychiatric illness and nonmental health-related factors that predict CPS custody arrangements.

OBJECTIVE

To identify clinical factors associated with newborns' custody under CPS for mothers with antenatal psychiatric hospitalization.

METHODS

We conducted a retrospective review of electronic medical records over a 10-year period (2012-2021) for patients who were pregnant during their inpatient psychiatric hospitalizations. We followed 81 patients (18 to 43 years old) who delivered within the hospital. The study endpoint was whether the newborn was placed under CPS custody. For the purposes of this study, psychiatric illness was categorized by the presence or absence of psychotic symptoms. We utilized logistic regressions to investigate the associations of these demographic and clinical factors with the study outcome of CPS custody.

RESULTS

For the entire study population, 64.2% of newborns had CPS custody arrangements. In multivariate analysis, after adjusting for potential confounders, patients with psychotic symptoms were at increased odds of having CPS custody arrangements (odds ratio = 8.43; 95% confidence interval 2.16-32.85) compared with patients without psychotic symptoms. Furthermore, multivariate analyses revealed that patients with a history of homelessness also had a higher risk (odds ratio = 6.59; 95% confidence interval: 1.24-35.13) of CPS custody arrangements for their newborns than those without a history of homelessness.

CONCLUSIONS

The results of this study suggest that among pregnant and psychiatrically hospitalized patients, those with psychotic symptoms are significantly more likely to have CPS custody arrangements compared to those without psychotic symptoms. However, it is important to note that psychotic symptoms were not definitive for the inability to parent appropriately. In fact, nearly 25% of the study population who had psychotic symptoms were able to successfully transition home with their newborns as mothers. This emphasizes the importance of optimizing the management of psychotic symptoms, particularly among those who have children or plan to have children. The findings of this study also highlight the chronic impacts that those who have struggled with homelessness may experience, including parenting capacity after homelessness resolves.

Social Determinants and Perinatal Hardships During the COVID-19 Pandemic

Background: This study examined perinatal experiences of pandemic-related hardships and disparities by race/ethnicity, income, insurance type at childbirth, and urban/rural residency. Materials and Methods: We used cross-sectional survey data from the 2020 Pregnancy Risk Assessment Monitoring System COVID-19 supplement in 26 states, the District of Columbia, and New York City to explore: (1) job loss or cut work hours/pay, (2) having to move/relocate or becoming homeless, (3) problems paying the rent, mortgage, or bills, or (4) worries that food would run out. We estimated the prevalence of outcomes overall and by race/ethnicity, income, insurance, and urban/rural residency. We used weighted multivariable logistic regression models to calculate adjusted predicted probabilities. Results: Due to the COVID-19 pandemic, 31.9% of respondents reported losing their job or having a cut in work hours or pay, 11.2% of respondents had to move/relocate or became homeless, 21.8% had problems paying the rent, mortgage, or bills, and 16.86% reported worries that food would run out. Compared to overall, rates of all hardships were higher among respondents who were non-Hispanic Black, Hispanic, uninsured, or Medicaid insured. The adjusted predicted probability of employment instability, financial hardships, and food insecurity was significantly higher among non-Hispanic Black respondents and respondents who were uninsured. The adjusted predicted probability of all hardships was significantly higher among respondents with Medicaid. Conclusions: Black, Medicaid-insured, and uninsured respondents were particularly vulnerable to perinatal hardships during COVID-19. Our results suggest a need to alleviate the overall and disparate consequences of hardships for individuals who gave birth during the COVID-19 pandemic.

Homelessness And Health: Factors, Evidence, Innovations That Work, And Policy Recommendations

On a single night in 2023, more than 653,000 people experienced homelessness in the United States. In this overview, we highlight structural and individual risk factors that can lead to homelessness, explore evidence on the relationship between homelessness and health, discuss programmatic and policy innovations, and provide policy recommendations. Health system efforts to address homelessness and improve the health of homeless populations have included interventions such as screening for social needs and medical respite programs. Initiatives using the Housing First approach to permanent supportive housing have a strong track record of success. Health care financing innovations using Medicaid Section 1115 waivers offer promising new approaches to improving health and housing for people experiencing homelessness. To substantially reduce homelessness and its many adverse health impacts, changes are needed to increase the supply of affordable housing for households with very low incomes. Health care providers and systems should leverage their political power to advocate for policies that scale durable, evidence-based solutions to reduce homelessness, including increased funding to expand housing choice vouchers and greater investment in the creation and preservation of affordable housing.

Short Interpregnancy Intervals Among Women Experiencing Homelessness in Colorado

Importance

Short interpregnancy intervals (SIPIs) are associated with increased risk of adverse maternal and neonatal outcomes. Disparities exist across socioeconomic status, but there is little information on SIPIs among women experiencing homelessness.

Objective

To investigate (1) differences in rates and characteristics of SIPIs between women experiencing homelessness and domiciled women, (2) whether the association of homelessness with SIPIs differs across races and ethnicities, and (3) whether the association between SIPIs of less than 6 months (very short interpregnancy interval [VSIPIs]) and maternal and neonatal outcomes differs between participant groups.

Design, Setting, and Participants

This cohort study used a Colorado statewide database linking the Colorado All Payer Claims Database, Homeless Management Information System, death records, and infant birth records. Participants included all women who gave birth between January 1, 2016, and December 31, 2021. Data were analyzed from September 1, 2022, to May 10, 2023.

Exposures

Homelessness and race and ethnicity.

Main Outcomes and Measures

The primary outcome consisted of SIPI, a binary variable indicating whether the interval between delivery and conception of the subsequent pregnancy was shorter than 18 months. The association of VSIPI with maternal and neonatal outcomes was also tested.

Results

A total of 77 494 women (mean [SD] age, 30.7 [5.3] years) were included in the analyses, of whom 636 (0.8%) were women experiencing homelessness. The mean (SD) age was 29.5 (5.4) years for women experiencing homelessness and 30.7 (5.3) years for domiciled women. In terms of race and ethnicity, 39.3% were Hispanic, 7.3% were non-Hispanic Black, and 48.4% were non-Hispanic White. Associations between homelessness and higher odds of SIPI (adjusted odds ratio [AOR], 1.23 [95% CI, 1.04-1.46]) were found. Smaller associations between homelessness and SIPI were found among non-Hispanic Black (AOR, 0.59 [95% CI, 0.37-0.96]) and non-Hispanic White (AOR, 0.57 [95% CI, 0.39-0.84]) women compared with Hispanic women. A greater association of VSIPI with emergency department visits and low birth weight was found among women experiencing homelessness compared with domiciled women, although no significant differences were detected.

Conclusions and Relevance

In this cohort study of women who gave birth from 2016 to 2021, an association between homelessness and higher odds of SIPIs was found. These findings highlight the importance of conception management among women experiencing homelessness. Racial and ethnic disparities should be considered when designing interventions.

Improving Reproductive Health Communication Between Providers and Women Affected by Homelessness and Substance Use in San Francisco: Results from a Community-Informed Workshop

OBJECTIVES

Many cisgender women affected by homelessness and substance use desire pregnancy and parenthood. Provider discomfort with patient-centered counseling about reproductive choices and supporting reproductive decisions of these women poses barriers to reproductive healthcare access.

METHODS

We used participatory research methods to develop a half-day workshop for San Francisco-based medical and social service providers to improve reproductive counseling of women experiencing homelessness and/or who use substances. Guided by a stakeholder group comprising cisgender women with lived experience and providers, goals of the workshop included increasing provider empathy, advancing patient-centered reproductive health communication, and eliminating extraneous questions in care settings that perpetuate stigma. We used pre/post surveys to evaluate acceptability and effects of the workshop on participants' attitudes and confidence in providing reproductive health counseling. We repeated surveys one month post-event to investigate lasting effects.

RESULTS

Forty-two San Francisco-based medical and social service providers participated in the workshop. Compared to pre-test, post-test scores indicated reduced biases about: childbearing among unhoused women (p < 0.01), parenting intentions of pregnant women using substances (p = 0.03), and women not using contraception while using substances (p < 0.01). Participants also expressed increased confidence in how and when to discuss reproductive aspirations (p < 0.01) with clients. At one month, 90% of respondents reported the workshop was somewhat or very beneficial to their work, and 65% reported increased awareness of personal biases when working with this patient population.

CONCLUSIONS FOR PRACTICE

A half-day workshop increased provider empathy and improved provider confidence in reproductive health counseling of women affected by homelessness and substance use.

Trends, Characteristics, and Maternal Morbidity Associated With Unhoused Status in Pregnancy

Importance

Unhoused status is a substantial problem in the US. Pregnancy characteristics and maternal outcomes of individuals experiencing homelessness are currently under active investigation to optimize health outcomes for this population.

Objective

To assess the trends, characteristics, and maternal outcomes associated with unhoused status in pregnancy.

Design, Setting, and Participants

This cross-sectional study analyzed data from the Healthcare Cost and Utilization Project National (Nationwide) Inpatient Sample. The study population included hospitalizations for vaginal and cesarean deliveries from January 1, 2016, to December 31, 2020. Unhoused status of these patients was identified from use of International Statistical Classification of Diseases, Tenth Revision, Clinical Modification code Z59.0. Statistical analysis was conducted from December 2022 to June 2023.

Main Outcomes and Measures

Primary outcomes were (1) temporal trends; (2) patient and pregnancy characteristics associated with unhoused status, which were assessed with a multivariable logistic regression model; (3) delivery outcomes, including severe maternal morbidity (SMM) and mortality at delivery, which used the Centers for Disease Control and Prevention definition for SMM indicators and were assessed with a propensity score-adjusted model; and (4) choice of long-acting reversible contraception method and surgical sterilization at delivery.

Results

A total of 18 076 440 hospital deliveries were included, of which 18 970 involved pregnant patients who were experiencing homelessness at the time of delivery, for a prevalence rate of 104.9 per 100 000 hospital deliveries. These patients had a median (IQR) age of 29 (25-33) years. The prevalence of unhoused patients increased by 72.1% over a 5-year period from 76.1 in 2016 to 131.0 in 2020 per 100 000 deliveries (P for trend < .001). This association remained independent in multivariable analysis. In addition, (1) substance use disorder (tobacco, illicit drugs, and alcohol use disorder), (2) mental health conditions (schizophrenia, bipolar, depressive, and anxiety disorders, including suicidal ideation and past suicide attempt), (3) infectious diseases (hepatitis, gonorrhea, syphilis, herpes, and COVID-19), (4) patient characteristics (Black and Native American race and ethnicity, younger and older age, low or unknown household income, obesity, pregestational hypertension, pregestational diabetes, and asthma), and (5) pregnancy characteristics (prior uterine scar, excess weight gain during pregnancy, and preeclampsia) were associated with unhoused status in pregnancy. Unhoused status was associated with extreme preterm delivery (<28-week gestation: 34.3 vs 10.8 per 1000 deliveries; adjusted odds ratio [AOR], 2.76 [95% CI, 2.55-2.99]); SMM at in-hospital delivery (any morbidity: 53.8 vs 17.7 per 1000 deliveries; AOR, 2.30 [95% CI, 2.15-2.45]); and in-hospital mortality (0.8 vs <0.1 per 1000 deliveries; AOR, 10.17 [95% CI, 6.10-16.94]), including case fatality risk after SMM (1.5% vs 0.3%; AOR, 4.46 [95% CI, 2.67-7.45]). Individual morbidity indicators associated with unhoused status included cardiac arrest (AOR, 12.43; 95% CI, 8.66-17.85), cardiac rhythm conversion (AOR, 6.62; 95% CI, 3.98-11.01), ventilation (AOR, 6.24; 95% CI, 5.03-7.74), and sepsis (AOR, 5.37; 95% CI, 4.53-6.36).

Conclusions and Relevance

Results of this national cross-sectional study suggest that unhoused status in pregnancy gradually increased in the US during the 5-year study period and that pregnant patients with unhoused status were a high-risk pregnancy group.
