Labour and delivery interventions in women with intellectual and developmental disabilities: a population-based cohort study

The Right to Sexuality, Reproductive Health, and Found a Family for People with Intellectual Disability: A Systematic Review

Although sexuality, reproductive health, and starting a family are human rights that should be guaranteed for all citizens, they are still taboo issues for people with intellectual disability (ID), and even more so for women with ID. This paper systematically reviews the current qualitative and quantitative evidence on the rights of people with ID in regard to Articles 23 (right to home and family) and 25 (health, specifically sexual and reproductive health) of the Convention on the Rights of Persons with Disabilities (CRPD). A systematic review of the current literature, following PRISMA 2020, was carried out in ERIC, PsychInfo, Scopus, PubMed, ProQuest, and Web of Science. In all, 151 articles were included for review. The studies were categorized into six themes: attitudes, intimate relationships, sexual and reproductive health, sexuality and sex education, pregnancy, and parenthood. There are still many barriers that prevent people with ID from fully exercising their right to sexuality, reproductive health, and parenthood, most notably communicative and attitudinal barriers. These findings underline the need to continue advancing the rights of people with ID, relying on Schalock and Verdurgo's eight-dimensional quality of life model as the ideal conceptual framework for translating such abstract concepts into practice and policy.

Autistic People's Perinatal Experiences II: A Survey of Childbirth and Postnatal Experiences

Qualitative accounts indicate there are sensory and communication related barriers to adequate childbirth and postnatal healthcare for autistic people. However, little quantitative work has explored the topic. This online survey study explored childbirth and postnatal experiences among 384 autistic and 492 non-autistic people. Compared with non-autistic people, autistic people were more likely to find the sensory aspects of birth overwhelming, and experienced lower satisfaction with birth-related and postnatal healthcare. Autistic people were more likely to experience postnatal depression and anxiety. The findings highlight that sensory and communication adjustments should be made to birth and postnatal healthcare for autistic people. The findings indicate the need for greater autism understanding among professionals and greater postnatal mental health support for autistic people.

Exploring patient safety outcomes for people with learning disabilities in acute hospital settings: a scoping review

OBJECTIVES

To produce a narrative synthesis of published academic and grey literature focusing on patient safety outcomes for people with learning disabilities in an acute hospital setting.

DESIGN

Scoping review with narrative synthesis.

METHODS

The review followed the six stages of the Arksey and O'Malley framework. We searched four research databases from January 2000 to March 2021, in addition to handsearching and backwards searching using terms relating to our eligibility criteria-patient safety and adverse events, learning disability and hospital setting. Following stakeholder input, we searched grey literature databases and specific websites of known organisations until March 2020. Potentially relevant articles and grey literature materials were screened against the eligibility criteria. Findings were extracted and collated in data charting forms.

RESULTS

45 academic articles and 33 grey literature materials were included, and we organised the findings around six concepts: (1) adverse events, patient safety and quality of care; (2) maternal and infant outcomes; (3) postoperative outcomes; (4) role of family and carers; (5) understanding needs in hospital and (6) supporting initiatives, recommendations and good practice examples. The findings suggest inequalities and inequities for a range of specific patient safety outcomes including adverse events, quality of care, maternal and infant outcomes and postoperative outcomes, in addition to potential protective factors, such as the roles of family and carers and the extent to which health professionals are able to understand the needs of people with learning disabilities.

CONCLUSION

People with learning disabilities appear to experience poorer patient safety outcomes in hospital. The involvement of family and carers, and understanding and effectively meeting the needs of people with learning disabilities may play a protective role. Promising interventions and examples of good practice exist, however many of these have not been implemented consistently and warrant further robust evaluation.

Association between mothers' postoperative opioid prescriptions and opioid-related events in their children: A population-based cohort study

BACKGROUND

Postoperative opioid prescriptions may be associated with risks of unintentional poisoning and drug diversion in other household members. The objective of this study was to explore the association between mothers' postoperative opioid prescriptions and incidence of opioid-related events in their children (aged 1 to 24 years).

DATA AND METHODS

This retrospective cohort study used individually linked administrative health data from Ontario, Canada. A population-based sample of 170,156 opioid-naïve mothers (aged 15 to 64) (see Figure 1) who underwent surgery between 2013 and 2017 in Ontario was linked through birth records to create a cohort of their 283,550 opioid-naïve children (aged 1 to 24). The association between postoperative opioid analgesic prescriptions filled by mothers within seven days of discharge after surgery and opioid-related events (emergency department presentations or inpatient admissions for opioid poisoning, or mental and behavioural disorders attributable to opioid use) in their children within one year of their mother's discharge was assessed.

RESULTS

Overall, 60.4% of the children in the cohort had a mother who filled a postoperative opioid prescription. The incidence of opioid-related events in children in the year after a mother's surgery was low overall (n=36/283,550, 0.01%), but higher among children whose mother filled a postoperative opioid prescription (n=29/171,139, 0.02%, vs. n=7/112,411, 0.01%, p=0.02), including in an analysis adjusting for child's age, mother's age, rural residence, neighbourhood income quintile and mother's Charlson comorbidity index score (adjusted odds ratio, 2.42 [95% confidence interval (CI), 1.05 to 5.54], p=0.04).

DISCUSSION

Postoperative opioid prescriptions for mothers may contribute to opioid-related events in their children. These findings further underscore the importance of safe, effective opioid prescribing, as well as of patient and public education about the use, storage and disposal of these medications.

Recent Trends and Future Directions in Research Regarding Parents with Intellectual and Developmental Disabilities

Purpose of Review

This report updates research on parents with IDD and their children published since 2014.

Recent Findings

Since 2014, a plethora of studies using large administrative databases in different countries support a contextual approach to understand why parents with IDD and their children may have worse outcomes than other families. In most studies, increased risk of ill health in women with IDD and health and developmental problems in their children were fully or partially accounted for by socioeconomic and psychosocial hardships. New research has found that pregnant women with IDD tend to have risk factors for pregnancy, birth, and postpartum complications that may contribute to adverse child outcomes. Intervention research is gradually becoming more contextualized.

Summary

More studies are needed on multicultural aspects of parenting, programs that could help parents with IDD overcome social and health disadvantages, comprehensive and coordinated service models that start during pregnancy, innovative parent support arrangements, parenting education for teens and young adults with IDD, use of technology, and dissemination and implementation of evidence-based programs.

Pregnancy and neonatal outcomes of women with disabilities: a nationwide population-based study in South Korea

We investigated (1) pregnancy and neonatal outcomes in women with and without disabilities, (2) time trends in deliveries, and (3) risks of pregnancy and neonatal complications among women with various disability types and severity. This was a nationwide population-based study merging the database of the Korea National Health Insurance claims, National Health Screening Program for Infants and Children, and Disability Registration System to compare perinatal outcomes in women with and without disabilities. Pregnancy and neonatal outcomes were analyzed during 2007 and 2015, as were time trends of deliveries. Multivariate logistic regression was used to evaluate risk of perinatal outcomes among women with various disability types and severities. Women with disabilities showed higher rates of cesarean section (aOR, 1.73; 95% CI, 1.69–1.77), hypertensive disorders (aOR, 1.74; 95% CI, 1.63–1.86), placenta abruption (aOR, 1.27; 95% CI, 1.12–1.45), placenta previa (aOR, 1.14; 95% CI, 1.05–1.24), stillbirths (aOR, 1.30; 95% CI, 1.17–1.45), preterm births (aOR, 1.67; 95% CI, 1.57–1.78), and LBW (aOR, 1.87; 95% CI, 1.78–1.97) than those without disabilities. From 2007 to 2015, although delivery rate in women with disabilities decreased steeply compared with that in women without disabilities, the rate of cesarean section increased in women with disabilities. Women with intellectual disability and those with vision impairment had the highest number of perinatal complications among women with various types of disabilities. Women with disability had more adverse pregnancy and neonatal outcomes than those without disabilities. Specific disability types & severities are more vulnerable to specific perinatal complications.

Prolonged postpartum length of hospital stay among women with disabilities

BACKGROUND

Prior studies have found higher proportions of cesarean deliveries and longer postpartum hospital stays among women with disabilities compared to women without disabilities. However, no research has assessed how length of stay may differ for women with different types of disability while also considering mode of delivery.

OBJECTIVE

To examine the association of disability status and disability type with length of stay, taking into account disability-related differences in mode of delivery.

METHODS

We conducted a retrospective cohort study using linked maternal and infant hospital discharge and vital records data for all births in California between 2000 and 2012 (n = 6,745,201). We used multivariable regression analyses to assess association of disability status and type with prolonged length of stay (>2 days for vaginal delivery or >4 days for cesarean) while controlling for covariates.

RESULTS

Women with disabilities had significantly elevated adjusted odds of prolonged length of stay compared to women without disabilities (aOR = 1.40, 95% CI = 1.32-1.49). Adjusted odds were highest for women with vision disabilities (aOR = 1.67, 95% CI = 1.46-1.90), followed by women with IDD (aOR = 1.53, 95% CI = 1.30-1.80), and women with physical disabilities (aOR = 1.41, 95% CI = 1.32-1.50). Women with hearing disability had the lowest adjusted odds of prolonged length of stay (aOR = 1.17, 95% CI = 1.03-1.33).

CONCLUSIONS

Prolonged length of stay did not appear to be due solely to the higher proportion of cesarean deliveries in this population. Further research is needed to better understand the reasons for prolonged length of stay among women with disabilities and develop strategies to assist women with disabilities in preparing for and recovering from childbirth.

Health care utilisation in infants and young children born to women with intellectual and developmental disabilities: A systematic review and meta-analysis

BACKGROUND

Mothers with intellectual and developmental disabilities (IDD) experience socio-economic and health disparities which could impact their offspring's health care utilisation. We systematically reviewed evidence on health care utilisation in infants and young children of women with and without IDD.

METHODS

MEDLINE, EMBASE, CINAHL, and PsycINFO were searched from inception to October 2019 for studies examining preventive care, immunisations, emergency department visits, and hospitalisations. Data extraction and quality assessment were performed using standardised tools. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were generated using random effects models for outcomes with data available from ≥3 studies.

RESULTS

Four articles describing three cohort studies and one cross-sectional study met our criteria. Maternal IDD status was associated with increased neonatal intensive care unit admission rates (pooled OR 2.03; 95% CI 1.31, 3.13). There were no differences in immunisation rates or hospitalisations.

CONCLUSIONS

Few studies have examined the impact of maternal IDD status on health care utilisation in their infants and young children. More high-quality studies are needed.

Maternal disability and risk for pregnancy, delivery, and postpartum complications: a systematic review and meta-analysis

BACKGROUND

Women with disabilities are increasingly becoming pregnant, and growing evidence suggests maternal disability may be associated with increased risk for perinatal complications.

OBJECTIVE

A systematic review and meta-analysis were undertaken to examine the association between maternal disabilities and risk for perinatal complications.

STUDY DESIGN

Medline, CINAHL, EMBASE, and PsycINFO were searched from inception to July 2018 for full-text publications in English on pregnancy, delivery, and postpartum complications in women with any disability and those with physical, sensory, and intellectual and developmental disabilities specifically. Searches were limited to quantitative studies with a comparison group of women without disabilities. Reviewers used standardized instruments to extract data from and assess the quality of included studies. Pooled odds ratios and 95% confidence intervals were generated using DerSimonian and Laird random effects models for outcomes with data available from ≥3 studies.

RESULTS

The review included 23 studies, representing 8,514,356 women in 19 cohorts. Women with sensory (pooled unadjusted odds ratio, 2.85, 95% confidence interval, 0.79-10.31) and intellectual and developmental disabilities (pooled unadjusted odds ratio, 1.10, 95% confidence interval, 0.76-1.58) had elevated but not statistically significant risk for gestational diabetes. Women with any disability (pooled unadjusted odds ratio, 1.45, 95% confidence interval, 1.16-1.82) and intellectual and developmental disabilities (pooled unadjusted odds ratio, 1.77, 95% confidence interval, 1.21-2.60) had increased risk for hypertensive disorders of pregnancy; risk was elevated but not statistically significant for women with sensory disabilities (pooled unadjusted odds ratio, 2.84, 95% confidence interval, 0.85-9.43). Women with any (pooled unadjusted odds ratio, 1.31, 95% confidence interval, 1.02-1.68), physical (pooled unadjusted odds ratio, 1.60, 95% confidence interval, 1.21-2.13), and intellectual and developmental disabilities (pooled unadjusted odds ratio, 1.29, 95% confidence interval, 1.02-1.63) had increased risk for cesarean delivery; risk among women with sensory disabilities was elevated but not statistically significant (pooled unadjusted odds ratio, 1.28, 95% confidence interval, 0.84-1.93). There was heterogeneity in all analyses, and 13 studies had weak-quality ratings, with lack of control for confounding being the most common limitation.

CONCLUSION

Evidence that maternal disability is associated with increased risk for perinatal complications demonstrates that more high-quality research is needed to examine the reasons for this risk and to determine what interventions could be implemented to support women with disabilities during the perinatal period.

Miscarriage Occurrence and Prevention Efforts by Disability Status and Type in the United States

Background: Very little is known about early pregnancy loss in women with disabilities. To address this gap, we analyzed nationally representative data on miscarriage and receipt of care focused on miscarriage prevention among women with and without disabilities. Materials and Methods: We used 2011-2015 National Survey of Family Growth data on women with at least one completed pregnancy within the past 5 years. Bivariate and multivariate analyses assessed the association of six disability categories (any, hearing, vision, cognitive, physical, independent living) with miscarriage occurrence and receipt of services intended to prevent miscarriage. Results: Our analytic sample included 3,843 women with 5,776 completed pregnancies within the past 5 years. Overall, 31.63% of women with disabilities and 21.83% of women without disabilities had had a miscarriage within the past 5 years. Compared to women without disabilities, women with any, cognitive, physical, and independent living disability had higher adjusted odds of experiencing miscarriage (any disability aOR = 1.65 [95% CI: 1.21-2.25]). These women also had higher odds of receiving services to prevent miscarriage compared with women without disabilities (any disability aOR = 1.71 [95% CI: 1.20-2.45]). Among women who received services, higher proportions of women with any, vision, physical, or independent living disability received recommendations for bed rest (e.g., 65.007% of women with independent living disability vs. 33.98% of women without disability, p = 0.018). Conclusions: In a representative sample of U.S. women, we found significant differences in the odds of miscarriage and in receipt of care to prevent miscarriage between women with and without disabilities. Further research is needed to understand why women with disabilities are more likely to experience a miscarriage. Such research is important for informing care recommendations.

Racial and ethnic disparities in birth outcomes and labour and delivery-related charges among women with intellectual and developmental disabilities

BACKGROUND

Women with intellectual and developmental disabilities (IDD) in the USA are bearing children at increasing rates. However, very little is known whether racial and ethnic disparities in birth outcomes and labour and delivery-related charges exist in this population. This study investigated racial and ethnic disparities in birth outcomes and labour and delivery-related charges among women with IDD.

METHODS

The study employed secondary analysis of the 2004-2011 Healthcare Cost and Utilization Project National Inpatient Sample, the largest all-payer, publicly available US inpatient healthcare database. Hierarchical mixed-effect logistic and linear regression models were used to compare the study outcomes.

RESULTS

We identified 2110 delivery-associated hospitalisations among women with IDD including 1275 among non-Hispanic White women, 527 among non-Hispanic Black women and 308 among Hispanic women. We found significant disparities in stillbirth among non-Hispanic Black and Hispanic women with IDD compared with their non-Hispanic White peers [odds ratio = 2.50, 95% confidence interval (CI): 1.16-5.28, P < 0.01 and odds ratio = 2.53, 95% CI: 1.08-5.92, P < 0.01, respectively]. There were no racial and ethnic disparities in caesarean delivery, preterm birth and small-for-gestational-age neonates among women with IDD. The average labour and delivery-related charges for non-Hispanic Black and Hispanic Women with IDD ($18 889 and $22 481, respectively) exceeded those for non-Hispanic White women with IDD ($14 886) by $4003 and $7595 or by 27% and 51%, respectively. The significant racial and ethnic differences in charges persisted even after controlling for a range of individual-level and institutional-level characteristics and were 6% (ln(β) = 0.06, 95% CI: 0.01-0.11, P < 0.05) and 9% (ln(β) = 0.09, 95% CI: 0.03-0.14, P < 0.01) higher for non-Hispanic Black and Hispanic Women with IDD compared with non-Hispanic White women with IDD.

CONCLUSIONS

Our findings highlight the need for an integrated approach to the delivery of comprehensive perinatal services for racial and ethnic minority women with IDD to reduce their risk of having a stillbirth. Additionally, further research is needed to examine the causes of racial and ethnic disparities in hospital charges for labour and delivery admission among women with IDD and ascertain whether price discrimination exists based on patients' racial or ethnic identities.

Differences in Prenatal Care by Presence and Type of Maternal Disability

INTRODUCTION

Prior studies have found that women with disabilities are less likely to receive adequate prenatal care than women without disabilities. However, little is known about differences in patterns of prenatal care by type of disability. Therefore, this study examined timing and frequency of prenatal care among women with physical, sensory, or intellectual/developmental disabilities compared with women without disabilities.

METHODS

This was a retrospective cohort study using linked maternal and infant hospital discharge and birth certificate data for all births in California in 2000-2012 (N=6,745,201). Analyses were conducted in 2017-2018. Modified Poisson regression analyses compared women with each type of disability with women without disabilities on trimester of prenatal care initiation and number of prenatal care visits.

RESULTS

Women with intellectual/developmental disabilities or with limited hearing had significantly higher RR of delaying prenatal care initiation until the second or third trimester (intellectual/developmental disabilities: adjusted RR=1.21, 95% CI=1.09, 1.33; hearing: adjusted RR=1.11, 95% CI=1.02, 1.21), whereas women with physical disabilities and limited vision had lower risk of delaying care (physical: adjusted RR=0.91, 95% CI=0.88, 0.94; vision: adjusted RR=0.85, 95% CI=0.73, 0.99). Women with limited hearing or vision or intellectual/developmental disabilities had higher risk of receiving fewer prenatal visits than recommended, compared with women without disabilities. Women with physical disabilities or intellectual/developmental disabilities had higher RR of receiving more than the typical number of visits.

CONCLUSIONS

There were key differences in prenatal care utilization by disability type, reflective of particularly pronounced disparities for women with intellectual/developmental disabilities and women with limited hearing. Delays in receipt of prenatal care and low numbers of prenatal care visits may contribute to the poorer birth outcomes that have been observed previously in these groups. Targeted interventions are needed to improve uptake of prenatal care in these vulnerable populations.

"I Didn't Need People's Negative Thoughts": Women With Intellectual and Developmental Disabilities Reporting Attitudes Toward Their Pregnancy

Background

Since the illegalization of involuntary sterilization of persons with intellectual and developmental disabilities, there has been an increase in childbearing in this population. However, women with intellectual and developmental disabilities continue to experience prejudicial attitudes toward their pregnancies.

Objective

To analyze the experiences of women with intellectual and developmental disabilities regarding their perceptions of support persons’ attitudes toward their pregnancies.

Methods

Three case studies derived from grounded theory research exploring perinatal social support received by women with intellectual and developmental disabilities. Using inductive content analysis, we further analyzed the perceptions of women with intellectual and developmental disabilities regarding support persons’ attitudes toward their pregnancies. Findings: The nature of interactions with support persons and women’s characteristics, such as help-seeking behaviors, disability, mental illness, and age, influenced support persons’ attitudes toward childbearing. Women preferred support from caregivers perceived as nonjudgmental and tended to restrict contact with persons perceived as prejudicial. However, some attitudes improved following positive interactions with the women. The relationship between support persons’ attitudes and the women’s help-seeking behaviors is thus complex.

Conclusions

Education of families and medical and social services practitioners and opportunities for positive contact should be further explored. Caseworkers of women with intellectual and developmental disabilities may have invaluable roles in facilitating positive interactions between women with intellectual and developmental disabilities and caregivers.

Modelling correlated data: Multilevel models and generalized estimating equations and their use with data from research in developmental disabilities

BACKGROUND

The use of Multilevel Models (MLM) and Generalized Estimating Equations (GEE) for analysing clustered data in the field of intellectual and developmental disability (IDD) research is still limited.

METHOD

We present some important features of MLMs and GEEs: main function, assumptions, model specification and estimators, sample size and power. We provide an overview of the ways MLMs and GEEs have been used in IDD research.

RESULTS

While MLMs and GEEs are both appropriate for longitudinal and/or clustered data, they differ in the assumptions they impose on the data, and the inferences made. Estimators in MLMs require appropriate model specification, while GEEs are more resilient to misspecification at the expense of model complexity. Studies on sample size seem to suggest that Level 1 coefficients are robust to small samples/clusters, with any higher-level coefficients less so. MLMs have been used more frequently than GEEs in IDD research, especially for fitting developmental trajectories.

CONCLUSIONS

Clustered data from research in the IDD field can be analysed flexibly using MLMs and GEEs. These models would be more widely used if journals required the inclusion of technical specification detail, simulation studies examined power for IDD study characteristics, and researchers developed core skills during basic studies.

Postpartum Hospital Utilization among Massachusetts Women with Intellectual and Developmental Disabilities: A Retrospective Cohort Study

Objectives This study examined the risk of postpartum hospital admissions and emergency department (ED) visits among US women with intellectual and developmental disabilities (IDD). Methods We used the 2002-2012 Pregnancy to Early Life Longitudinal Data System and identified deliveries to women with and without IDD. Women with IDD (n = 1104) or case subjects were identified from the International Classification of Diseases and Related Health Problems 9th Revision (ICD-9 CM) codes. The study primary outcome measures were any postpartum hospital admission and any ED visit during three critical postpartum periods (1-42, 43-90, and 1-365 days). We conducted unadjusted and adjusted survival analysis using Cox proportional hazard models to compare the occurrence of first hospital admission or ED visits between women with and without IDD. Results We found that women with IDD had markedly higher rates of postpartum hospital admissions and ED visits during the critical postpartum periods (within 1-42, 43-90, and 91-365 days) after a childbirth. Conclusion for Practice Given the heightened risk of pregnancy complications and adverse birth outcomes and the findings of this study, there is an urgent need for clinical guidelines related to the frequency and timing of postpartum care among new mothers with IDD. Further, this study provides evidence of the need for evidence-based interventions for new mothers with IDD to provide preventive care and routine assessments that would identify and manage complications for both the mother and the infant outside of the traditional postpartum health care framework.

Antenatal Hospitalization Among U.S. Women With Intellectual and Developmental Disabilities: A Retrospective Cohort Study

This population-based retrospective cohort study examines the prevalence of hospital utilization during pregnancy and the primary reason for antenatal hospital utilization among women with intellectual and developmental disabilities (IDD). Massachusetts residents with in-state deliveries that were ≥ 20 weeks gestational age were included via data from the 2002-2009 Massachusetts Pregnancy to Early Life Longitudinal Data System. Among women with IDD, 54.8% had at least one emergency department (ED) visit during pregnancy, compared to 23% of women without IDD. Women with IDD were more likely to have an antenatal ED visit, observational stays, and non-delivery hospital stays. This study highlights the need for further understanding of the health care needs of women with IDD during pregnancy.

Review of gynecologic and reproductive care for women with developmental disabilities

PURPOSE OF REVIEW

Care for women with developmental disabilities requires special consideration for unique needs related to their cognitive and physical abilities. These women and their caregivers require more support and guidance during reproductive health care. We review the literature and provide expert opinion surrounding gynecological issues for women with developmental disabilities to support healthcare providers better understand and care for this population.

RECENT FINDINGS

Women with developmental disabilities are more vulnerable to abuse and experience poorer gynecological healthcare outcomes. Many women with developmental disabilities are fertile and participate in sexual activity without adequate knowledge. They are at higher risk of pregnancy and birth complications. They are less likely to receive appropriate preventive screening.

SUMMARY

The review highlights important issues and practice suggestions related to the reproductive health care of women with developmental disabilities. Topics include clinic visits, menstruation, sexuality, sexual abuse, sexual health education, contraception, sexually transmitted infections, pregnancy, labor and delivery, and cancer screening/prevention. We emphasize the need for an individualized, comprehensive approach for these patients and review perceived and actual barriers to care. More education is needed on the aforementioned topics for women with developmental disabilities, their caregivers, and their providers.

Primary Cesarean Delivery Patterns among Women with Physical, Sensory, or Intellectual Disabilities

BACKGROUND

Little is known about the relationship between disability and mode of delivery. Prior research has indicated elevated risk of cesarean delivery among women with certain disabilities, but has not examined patterns across multiple types of disability or by parity.

OBJECTIVE

This study sought to determine whether physical, sensory, or intellectual and developmental disabilities are independently associated with primary cesarean delivery.

METHODS

We conducted a retrospective cohort study of all deliveries in California from 2000 to 2010 using linked birth certificate and hospital discharge data. We identified physical, sensory, and intellectual and developmental disabilities using International Classification of Diseases, 9th revision, clinical modification codes. We used logistic regression to examine the association of these disabilities and primary cesarean delivery, controlling for sociodemographic characteristics and comorbidities, and stratified by parity.

RESULTS

In our sample, 0.45% of deliveries (20,894/4,610,955) were to women with disabilities. A greater proportion of women with disabilities were nulliparous, had public insurance, and had comorbidities (e.g., gestational diabetes) compared with women without disabilities (p < .001 for all). The proportion of primary cesarean in women with disabilities was twice that in women without disabilities (32.7% vs. 16.3%; p < .001; adjusted odds ratio, 2.05; 95% confidence interval, 1.94-2.17). The proportion of deliveries by cesarean was highest among women with physical disabilities due to injuries compared with women without disabilities (57.8% vs. 16.3%; p < .001; adjusted odds ratio, 6.83; 95% confidence interval, 5.46-8.53).

CONCLUSIONS

Women across disability subgroups have higher odds of cesarean delivery, and there is heterogeneity by disability type. More attention is needed to this population to ensure better understanding of care practices that may impact maternal and perinatal outcomes.
