Abstract

Background:

Women with intellectual and developmental disabilities face poorer reproductive and pregnancy outcomes partially due to health care inequity. Our objective was to conduct a scoping review of reproductive and pregnancy related health care among women with intellectual and developmental disabilities.

Methods:

We systematically reviewed three databases for keywords pertaining to pregnancy, reproductive health, and intellectual and developmental disabilities. Two reviewers screened abstracts and extracted full text. We synthesised included papers, identifying common themes.

Results:

Thirty-six papers met review criteria. Women with intellectual and developmental disabilities had lower fertility rates and were less likely to receive adequate sexual education compared to peers. While most women received prenatal care, uptake was lower and received later than women without intellectual and developmental disabilities.

Conclusions:

Pregnancy-related health care is often lacking for women with intellectual and developmental disabilities. There are gaps inhibiting our understanding which prevents action to reduce health disparities.

Keywords: family planning, fertility, intellectual and developmental disabilities, midwife, prenatal care

1 ∣. INTRODUCTION

There is a long, tragic history of sterilisation, sexual violence and human rights violations against individuals with intellectual and developmental disabilities. The eugenics movement of the late 19th century made common the practice of sterilising women with intellectual and developmental disabilities across the globe, with some countries still legally allowing forced sterilisation (Rowlands & Amy, 2019). A systematic review of studies from 1990 to 2020 found prevalence of sexual abuse in women with intellectual disability to be 31.8 per 100 women (Tomsa et al., 2021). The societal stigma of having an intellectual and developmental disability can be pervasive and often manifests as a lack of opportunity and support in starting families (Ditchman et al., 2016). The effects of these abhorrent practices still manifest in healthcare practices and societal perceptions today.

Intellectual and developmental disabilities are conditions that cause impairment in cognitive and adaptive functioning before the age of 18 years and include conditions such as autism, cerebral palsy, Down syndrome and fragile X syndrome (National Institute of Child Health and Human Development, 2016) and these conditions should not impact one's reproductive freedom. As of 2017, approximately 7.4 million people in the U.S. had an intellectual and developmental disabilities (Residential Information Systems Project, 2020; Zablotsky et al., 2015). As larger cohorts of young adults with intellectual and developmental disabilities age into their reproductive years, sexual and reproductive health will continue to be crucial area of study. Progress is being made, with a strong literature on sexuality and promoting healthy sexual relationships within the intellectual and developmental disability population (Chrastina & Večeřová, 2018; Holmes et al., 2014; Medina-Rico et al., 2017); yet less is known on pregnancy-related care and whether the increase in sexual-health promotion has effects for pregnancy. It is imperative to understand pregnancy experiences and outcomes as people with intellectual and developmental disabilities deserve the same reproductive and parenting rights and opportunities as peers.

Issues of pregnancy are particularly important because of the lifelong consequences of negative outcomes for parent and child. Women1 with intellectual and developmental disabilities may be less likely to get pregnant (Brown et al., 2020). Once pregnant, women with intellectual and developmental disabilities are more likely to experience negative perinatal, delivery, and postpartum health outcomes, including gestational diabetes, hypertensive disorders of pregnancy, haemorrhage, emergency department visits, and caesarean section compared to peers (Tarasoff, Murtaza, et al., 2020). Additionally, newborns of women with intellectual and developmental disabilities are at increased risk of neonatal morbidity—including low birthweight, preterm birth, neonatal intensive care unit (NICU) admission and neonatal mortality (Rubenstein et al., 2020; Tarasoff, Ravindran, et al., 2020). The specific mechanisms that lead to increased risk of morbidity and mortality for women with intellectual and developmental disabilities and their newborns are less understood.

The study of sexual health and pregnancy among women with intellectual and developmental disability is a burgeoning field with reviews focusing on a variety of topics. Tarasoff, Murtaza, et al. (2020) and Tarasoff, Ravindran, et al. (2020) have examined maternal and infant pregnancy outcomes summarising the increased risk for a variety of pregnancy-related morbidity broadly among women with disabilities. In 2015, Homeyard et al. (2016) synthesised the literature on antenatal care for women with intellectual disability, highlighting the role of maternity care providers. Verlenden et al. (2019) evaluated the literature on contraception use for adolescents and adults with intellectual and developmental disability, finding contraception was underutilised among women with intellectual and developmental disability, and when used, was widely prescribed to manage menses and hormone dysregulation. While past reviews are useful, some are focused on just one area of reproductive health, examined just one intellectual and developmental disability subtype or disability more broadly, or need to be updated based on the influx of new papers on reproductive health and intellectual and developmental disability. Therefore, we conducted a scoping review to synthesise the existing state of practice and research for sexual and reproductive care surrounding pregnancy for women with intellectual and developmental disabilities. We were able to build off of themes from previous reviews while highlighting research gaps and areas needed for intervention and action.

2 ∣. METHODS

A scoping review is an approach to research synthesis that provides an overview of research in a particular area, focusing more on state of the research field rather than answering a specific scientific question (Sucharew, 2019). Because of the breadth of topics related to reproductive and sexual health, plus the emergence of this field, we elected to conduct a scoping review with systematic search methods. With a scoping review approach, we were able to examine the course of sexual health for women with intellectual and developmental disability, from sexual education to postnatal care, while exploring specific differences by intellectual and developmental disability type (e.g., autism and learning disability).

Our information sources included three major databases: PubMed, Embase and Web of Science. We used best practices endorsed by and documented in the Cochrane Handbook for Systematic Reviews for Interventions (Higgins et al., 2019), which included optimised search strategies for each database and using search terms carefully chosen to maximise sensitivity and precision. The databases were searched through December 2020. In addition, we conducted a hand search of known articles and articles cited by review articles.

Concepts used in the search were: doulas, midwives, birth attendants, pregnancy, prenatal care, antenatal care, fertility, fecundity, prenatal education, antenatal education and family planning services, to capture the reproductive lifespan of women. These were paired with the specific intellectual and developmental disabilities encompassed by the scope of this study such as cerebral palsy and autism spectrum disorder. Final searches used can be found in Supplement 1.

Our inclusion criteria were observational studies of reproductive health or pregnancy in women with intellectual and developmental disabilities. We did not exclude intervention studies but did exclude randomised clinical trials, since trial exclusion criteria may impart bias (Kahan et al., 2015). We excluded papers if they were not in English, they were published before 2000 (to describe the most up to date literature), the infant had intellectual and developmental disabilities rather than the mother, the study was after the post-partum period, or the study only assessed pregnancy outcomes rather than pregnancy care. Two researchers screened all titles and abstracts for relevance while a third resolved disagreements. If a study met entry criteria after abstract review, full texts were reviewed. If a study met entry criteria after full text review, two researchers independently extracted data on year, study design, key findings and limitations.

Our synthesis was guided by the methodological work on scoping reviews of Peters et al. (2015) and the inductive approach to exploratory data analysis (Goddard & Melville, 2001). After data collection, our study team met regularly to discuss key topics and identify patterns as they emerged over the course of the review. We developed our observations into themes, which we refined throughout the scoping review process. We quantitatively (number of papers) and qualitatively (strength of papers) assessed topics to identify key areas for presentation.

3 ∣. RESULTS

3.1 ∣. Study descriptions

We identified 5464 papers through our systematic search and 9 from a hand search. Ultimately, 36 manuscripts met criteria for our scoping review (Figure 1). Common reasons for exclusion were that the study focused on typically developing parents of children with intellectual and developmental disabilities, the study was focused on parenting rather than pregnancy, and intellectual and developmental disability was not differentiated from other disability. Studies varied in sample size (N = 4–21,181) with a variety of different methods, including registry-based analyses and qualitative studies. The list of conditions included in the definition of intellectual and developmental disabilities differed slightly across studies and we have highlighted when studies looked at a specific intellectual and developmental disabilities condition or used a different categorisation of intellectual and developmental disabilities conditions (e.g., ‘cognitive disability’).

Articles excluded if they were not in English, were published before 2000 (to describe the most up to date literature), the infant had intellectual and developmental disabilities rather than the mother, the study was after the post-partum period, or they only assessed pregnancy outcomes rather than pregnancy care

3.2 ∣. Identifying key areas

Upon examining the studies, we identified five key areas: fertility, family planning (including contraceptive use), prenatal care, use of midwives and doulas and post-delivery care. There have been previously published reviews on some of these topic areas (Homeyard et al., 2016; McCann et al., 2019; Verlenden et al., 2019). We evaluated the articles cited by these reviews and aimed to update their findings, expand to more areas of intellectual and developmental disabilities, and place findings within the context of wider intellectual and developmental disabilities pregnancy care research.

3.3 ∣. Fertility and fecundity

We identified three articles surrounding fertility and fecundity for women with intellectual and developmental disabilities (Table 1), with two being studies using Ontario health care system data. Fertility rates for women with intellectual and developmental disabilities were found to be lower than that of peers (Brown et al., 2019; Brown, Cobigo, et al., 2016; Brown, Lunsky, et al., 2016) with one potential mechanism being reduced fecundity (Birkebaek et al., 2002). Fertility rates comparing women with and without intellectual and developmental disabilities were more similar among younger age groups (18- to 24-years-old) (Brown et al., 2019; Brown, Cobigo, et al., 2016; Brown, Lunsky, et al., 2016). In the Ontario registry, intellectual and developmental disabilities was identified using International Classification of Disease codes, which can reliably identify intellectual and developmental disabilities, but may miss those with less severe presentation.

3.4 ∣. Sexual education, contraceptive use and pregnancy timing

Ten studies focused on family planning, which encompassed sexual education, contraceptive use, and timing and desire for pregnancy (Table 2). These studies were conducted in a wide range of settings, with many focusing on intellectual disability or learning disability. Studies found that women with intellectual and developmental disabilities were less likely to receive adequate sexual education compared to peers (Conder et al., 2011; Höglund & Larsson, 2013) and when they did receive sexual education, it was more focused on hygiene and menstruation rather than reproduction (Frawley & Wilson, 2016) with little information about contraception (Conder et al., 2011; Höglund & Larsson, 2013).

3.5 ∣. Prenatal care

There were 17 studies that examined prenatal care for women with intellectual and developmental disabilities (Table 3). While a high percentage of women with intellectual and developmental disabilities received prenatal care (Höglund et al., 2012; Pohl et al., 2020; Rubenstein et al., 2020), uptake of prenatal care was significantly lower and received later than women without intellectual and developmental disabilities (Horner-Johnson, 2019; Malouf, Henderson, et al., 2017; Mitra et al., 2015; Mueller et al., 2019; Redshaw et al., 2013). While less likely to have regular prenatal visits (Horner-Johnson, 2019), women with intellectual and developmental disabilities were more likely to have emergency department visits during pregnancy compared to peers (Mitra et al., 2018). Studies found that specific adaptations may be needed to ensure women receive adequate care, as many reported a lack of satisfactions with current care (Höglund et al., 2013; Homeyard & Patelarou, 2018; Malouf, Henderson, et al., 2017; Malouf, McLeish, et al., 2017; Pohl et al., 2020; Redshaw et al., 2013).

3.6 ∣. Midwife and doula care

In examining midwife and doula care, we found six papers that met our eligibility criteria (Table 4). Studies found that midwives adapted their care to meet needs of women with intellectual and developmental disabilities (Höglund & Larsson, 2015; Höglund & Larsson, 2019; McGarry et al., 2015), suggesting that midwife/doula care may be an important tool to improve care for women with intellectual and developmental disabilities. However, many midwives/doulas do not receive training in caring for women with intellectual and developmental disabilities (Höglund & Larsson, 2013; Höglund & Larsson, 2019; Homeyard & Patelarou, 2018; McGarry et al., 2015).

We identified five papers focused on post-delivery care (Table 5). Two papers focused on intellectual disability, two focused on learning disability and one on intellectual and developmental disabilities. Women with learning disability (Malouf, McLeish, et al., 2017), women with intellectual disability (Mueller et al., 2019), and Black women with intellectual and developmental disabilities (Akobirshoev et al., 2018) had longer hospital stays after birth compared to women without intellectual disability and white women with intellectual and developmental disabilities, respectively, although one paper found no significant difference between groups (Redshaw et al., 2013).

4 ∣. DISCUSSION

The objective of our scoping review was to synthesise the existing state of practice and research for sexual and reproductive care surrounding pregnancy for women with intellectual and developmental disabilities. While previous research has focused on reporting negative pregnancy outcomes among this population, we aimed to characterise the existing literature surrounding the emergent area of health care research. Through scoping review methodology, we were able to discern current gaps in the literature and identify potential areas for intervention regarding the reproductive care provided to women with intellectual and developmental disabilities. We found that women with intellectual and developmental disabilities had lower fertility rates, were less likely to receive adequate sexual education, were less likely to receive prenatal care and accessed it later into their pregnancy than women without intellectual and developmental disabilities. We also found that midwife and/or doula care may lend itself to the improvement of reproductive health care for women with intellectual and developmental disabilities.

4.1 ∣. Fertility and family planning

We found few studies describing the fertility of women with intellectual and developmental disabilities with some suggested evidence that fertility rate is lower compared to peers without intellectual and developmental disabilities (Rowlands & Amy, 2019). The fertility rates and scarcity of studies in this area are likely a result of the historic and current stigma, ableism and lack of opportunity surrounding pregnancy for women with intellectual and developmental disabilities. Fertility and fecundity rates are highly associated with other sociological factors (Vollset et al., 2020), so more work is needed in different countries, regions, and contexts. Our review found that women with intellectual and developmental disabilities were less likely to receive appropriate sexual education and family planning services compared to peers. For many women, family planning services are their usual and only source of health care (Frost, 2013; Sonfield et al., 2014). The availability of these family planning services, and thus a reduction in unintended pregnancy, contributes to improved health outcomes for women and children (Centers for Disease Control and Prevention, 1999; Gipson et al., 2008; Sonfield et al., 2014; Tsui et al., 2010). Consequently, these services are essential for women with intellectual and developmental disabilities and their provision may be especially beneficial based on the poor pregnancy outcomes currently observed.

4.2 ∣. Prenatal care

In our review, we found women with intellectual and developmental disabilities were less likely to receive prenatal care, and initiated care later compared to peers. Many reported dissatisfaction with their care. The gaps in prenatal care are a major challenge for improving health for pregnant people with intellectual and developmental disabilities. Prenatal care improves pregnancy outcomes. People who receive prenatal care are three to four times less likely to die from pregnancy-related complications than women who do not receive prenatal care (Bingham et al., 2011). Infants born to people who receive prenatal care are five times less likely to die in infancy than those born to mothers who did not receive care (Office of Women's Health, 2017). Additionally, access to and utilisation of adequate prenatal care is associated with a reduced risk for pregnancy complications, labour complications (Ekwempu, 1988), and negative fetal outcomes, such as low birth weight and preterm birth (Barros et al., 1996). Women with intellectual and developmental disabilities face various individual and structural barriers when trying to access reproductive health care. Barriers include a lack of accessible information, stigma, negative physician attitudes (Horner-Johnson et al., 2019), and fear or distrust of medical providers (Phillippi, 2009). It is likely that delayed or inadequate prenatal care contributes to disparities in outcomes for people with intellectual and developmental disabilities.

4.3 ∣. Midwives, doulas and post-partum care

We found a small literature highlighting the potential for midwives and doulas to partner with pregnant people with intellectual and developmental disabilities; yet many midwives and doulas do not receive training or guidance in working with people with intellectual and developmental disabilities. In the general literature, we see that midwives and doulas can have a profound impact on maternal and infant health through the prenatal and postnatal periods. Continuous support by these trained professionals provides women with empowerment to communicate her needs, the ability to make informed decisions, and various improved outcomes for the mother and her child (Biro, 2011; Gruber et al., 2013; Steel et al., 2014; Tarkka et al., 2000). Mothers who utilised doula services were found to be two times less likely to experience birth complications and four times less likely to have a low birthweight baby; these positive effects were even greater for under-resourced women (Gruber et al., 2013). The benefits of midwife/doula care may decrease multi-day postnatal stays in the hospital. Midwives and doulas may lack resources and be under-utilised by the general population due to over-medicalisation of pregnancy care (Shaw, 2013), which impacts uptake for women with intellectual and developmental disabilities. Standard health care systems may not be as quick to adapt to the needs of women with intellectual and developmental disabilities or other complications, but the specialty of midwife and doula care may help bridge the gap during this time.

4.4 ∣. Recommendations

There is a need for vast improvements in the resources and services provided to women with intellectual and developmental disabilities regarding sexual and reproductive health care. While research on this topic is increasing, many gaps still exist. It is necessary to fill those gaps so that action can be taken; a better and more complete understanding of the issue will allow for the efficacious recommendations to be put forth. Based on the scoping review and the literature, the following are promising suggestions.

Accessible, appropriate sexual health education for individuals with intellectual and developmental disabilities in schools will increase knowledge about healthy relationships, reproductive health, contraceptive methods and family planning resources. Specialised training of health care professionals to provide comprehensive care to women with intellectual and developmental disabilities will also be valuable. Areas for improvement within the health system include implicit bias or stigma training for health care providers, allotting more time for appointments for patients with intellectual and developmental disabilities, and utilising different avenues of disseminating information so that it is accessible to all (e.g., brochures, easy read format, fewer words, direct language, pictures and modelling). To ensure health equity, it is imperative to address both systemic and intersectional barriers. While improvements should be made to the overarching systems of health care, midwife and doula care may help provide support, uphold autonomy, and improve outcomes for women with intellectual and developmental disabilities in the interim. It is also important to identify clinical and community experts to guide interventions.

4.5 ∣. Limitations

Our research includes several important limitations. First, we excluded literature not written in English; this may have led to the exclusion of important articles related to our topic. Some identified articles included women with intellectual and developmental disabilities but did not contain data related to that population specifically and were thus excluded. For example, several articles included women with intellectual and developmental disabilities into broader categories of ‘women with disabilities’ or ‘women with multiple disabilities’, while others considered certain intellectual and developmental disabilities (e.g., cerebral palsy) to be defined as physical rather than learning/cognitive disabilities. The varying categorisation may have limited our ability to identify issues affecting all women with intellectual and developmental disabilities. We excluded grey literature which may have excluded important but unpublished findings. Lastly, we chose to perform a scoping review rather than a systematic review. A scoping review allowed us to provide an overview of the available research, but was less thorough than a systematic review, preventing us from providing meta-analytic estimates and producing a summary answer to a specific research question.

One current challenge related to this developing body of literature is that intellectual and developmental disabilities encompass a heterogeneous group of conditions. Intellectual and developmental disabilities include conditions such as cerebral palsy, Down syndrome, and autism, among others. The exact definition of intellectual and developmental disabilities, as well as the different categories of intellectual and developmental disabilities, often varies based on the source of information (National Institute of Child Health and Human Development, 2016). Findings from our scoping review reflect many different definitions for our population of interest. Identified literature utilised the categories of intellectual and developmental disabilities, intellectual disability, learning disability and cognitive disability, each of which incorporated various definitions of the conditions. Additionally, multiple articles that we included in our scoping review researched only specific sub conditions of intellectual and developmental disabilities, such as Asperger's syndrome or Turner syndrome. Some studies also included women who were self-diagnosed, adding to the complexity of defining intellectual and developmental disabilities. The vast variability in how intellectual and developmental disabilities is defined across studies makes it difficult to synthesise findings and suggest population-specific recommendations. More consistent definitions or more refined classifications are needed to meta-analyse estimates.

5 ∣. CONCLUSION

The findings of this scoping review indicate that women with intellectual and developmental disabilities had lower fertility rates, were less likely to access comprehensive sexual education, were less likely to receive prenatal care, and received it later into their pregnancy than women without intellectual and developmental disabilities. Our findings suggest an urgent need to expand research regarding the sexual and reproductive health of women with intellectual and developmental disabilities and to develop appropriate and accessible interventions to support their needs.
