The complex array of antecedents of depression in women with physical disabilities: Implications for clinicians

Are physically disabled people at high risk of coronary heart disease among disabled population - Evidence from 7.5-year retrospective cohort study

OBJECTIVES

Previous cross-sectional studies suggested that people with physical disabilities (one of the subgroups of disabled people) are associated with an increased risk of cardiovascular diseases (CVD) than healthy peers. However, a longitudinal cohort of disabled people exhibited a different trend, in which the study populations were similar in health inequalities. We aimed to examine whether physical disability was associated with an increased risk of coronary heart disease (CHD) among disabled people.

STUDY DESIGN AND SETTING

This retrospective cohort study from the Shanghai Health Examination Program included a total of 6419 disabled adults (50.77 [9.88] age) with complete electronic health records and were free of CHD at baseline (2012) were followed-up for a 7.5-year period until 2019. The physical disability and non-physical disability subgroups were characterized based on the Disability Classification and Grading Standard (GB/T 26341-2010). Multivariable Cox regression analyses were used to evaluate adjusted hazard ratios (HR) for subsequent CHD, while Kaplan-Meier curves was used to assess the proportional hazards assumption. We conducted subgroup analyses based on gender, levels of disability, and baseline blood pressure.

RESULTS

Kaplan-Meier analysis revealed a higher incidence of CHD in the physical disability group compared to the non-physical disability group during the 7.5-year follow-up period (P < 0.05). Subjects with physical disabilities exhibited an increased risk for subsequent CHD occurrence (HR: 1.12; 95% CI: 1.03-1.31), compared to the non-physical subgroup after adjustments for confounders. The sensitivity analysis conducted on subgroups according to gender and disability severity indicated that moderate physical disability and female physical disability were associated with a higher prevalence of CHD, which was confirmed by multi-adjusted regression analysis. The spline curves of BP and CHD indicated that the physical disability group displayed lower SBP and DBP thresholds of 120 mmHg and SBP, respectively.

CONCLUSION

Within the disabled population, individuals with physical disability are at higher risk of developing CHD, and it is plausible that their optimal BP threshold for CHD prevention may need to be set at a lower level. Further research is essential to investigate BP management among individuals with physical disabilities and its influence on cardiovascular-related adverse events.

Greater engagement in valued activities is associated with less barriers to quitting smoking among smokers with mobility impairments

BACKGROUND

Individuals with mobility impairments (MI; use equipment to ambulate) have a high prevalence of both smoking and depression. Behavioral activation (BA) purports that depressed mood is remediated through valued activity engagement and may facilitate smoking cessation in MI populations.

OBJECTIVE

We examined cross-sectional associations between activity engagement and variables important for smoking cessation among a high-risk group of smokers (people with MIs) and also describe a smoking cessation intervention based on BA, given the lack of studies on smokers with MIs.

METHODS

This study used data from a smoking cessation trial enrolling smokers with MIs (n = 263). We assessed valued activities, activity type, activity restriction due to MI, and replacement of restricted activities. Motivation and confidence to quit smoking, number of cigarettes per day, and mood were also assessed. Analysis was performed with generalized linear (or logistic) regression models adjusted for age and physical functioning using aggregated data at baseline.

RESULTS

Greater number and frequency of valued activities was associated with less smoking, depression, negative affect, and stress and higher positive affect and self-efficacy to quit. Activity restriction was associated with greater odds of major depression, and activity replacement with lower odds of major depression, lower stress, and higher positive affect and self-efficacy. Strength of associations varied by activity type.

CONCLUSIONS

Consistent with our theoretical model, BA activity constructs were associated with several mediators of smoking outcomes in the expected directions. Smokers engaging in valued activities have more favorable profiles for smoking cessation and mood management.

Depressive symptoms during the perinatal period by disability status: Findings from the United States Pregnancy Risk Assessment Monitoring System

AIMS

The aim of the current study was to compare the prevalence of depressive symptoms during the perinatal period among respondents with a disability as compared to those without a disability.

DESIGN

We conducted a secondary analysis of nationally representative data from the Pregnancy Risk Assessment Monitoring System data from 24 participating United States between 2018 and 2020.

METHODS

A cross-sectional sample of 37,989 respondents provided data on disability, including difficulty in vision, hearing, ambulation, cognition, communication and self-care. The outcome of interest was perinatal depressive symptoms, defined as experiencing depressive symptoms during the antenatal period or postpartum period. Regression models were used to calculate odds of depressive symptoms during these two time periods by disability status while controlling for relevant sociodemographic characteristics and depressive symptoms prior to pregnancy.

RESULTS

Respondents with disabilities experienced a higher prevalence of depressive symptoms in both the antenatal period and postpartum period as compared to those without disabilities. In fully adjusted models, respondents with disabilities had 2.4 times the odds of experiencing depressive symptoms during pregnancy and 2.1 times the odds of experiencing postpartum depressive symptoms as compared to respondents without disabilities.

CONCLUSION

Respondents with disabilities experience a higher prevalence of depressive symptoms throughout the perinatal period thereby increasing the risk for adverse maternal, neonatal and infant health outcomes.

IMPACT

Perinatal depression is a significant public health issue globally, and our findings suggest that persons with disability are at an increased risk for depressive symptoms both during pregnancy and in the postpartum period. Our findings represent a call to action to improve clinical and supportive services for women with disabilities during the perinatal period to improve their mental health and the consequent health of their offspring.

Medication use during pregnancy among women with congenital physical disabilities

BACKGROUND

Medication use during pregnancy is common, with up to 90% of pregnant women taking at least one medication. Women with congenital physical disabilities often report co-occurring conditions during pregnancy that may warrant pharmaceutical treatment, however, research is limited. We aim to describe medication use during pregnancy including: pain, psychotropic, and antibacterial medication, among women with and without congenital physical disabilities.

METHODS

We used data from the Slone Birth Defects Study (1976-2015), a case-control study that collected information on pre-pregnancy health conditions and exposures among participating mothers. Women with congenital physical disabilities (n = 132) included women with spina bifida, cerebral palsy, muscular dystrophy, limb deficiencies, and other skeletal/connective tissue conditions and were matched by interview year and study site to women without congenital physical disabilities (n = 528). Proportions and difference in proportions for each medication were compared between groups. Simple proportions were also calculated for duration and multiple medication use variables.

RESULTS

Women with congenital physical disabilities more frequently reported use of pain (acetaminophen and opioids), psychotropic (antidepressants), and antibacterial medications during pregnancy. Women with congenital physical disabilities used pain and psychotropic medications for longer, frequent durations, and more frequently reported haven taken multiple medications during pregnancy.

CONCLUSION

Women with congenital physical disabilities report higher medication use during pregnancy compared to women without physical disabilities. Patterns may be attributable to co-occurring conditions or increased risk of pregnancy complications in this population. Further research is needed to describe the patterns of medication use for clinical decisions regarding treatment of pregnant women with disabilities.

Birth outcomes among women with congenital neuromuscular disabilities

BACKGROUND

Women with disabilities are at an increased risk for adverse birth outcomes; however, research among women with congenital neuromuscular disabilities (CNMD) is limited.

OBJECTIVE

To describe characteristics and compare birth outcomes among mothers with and without cNMD.

METHODS

Data were from the Slone Birth Defects Study (case-control, conducted from 1976 to 2015), which collected information on demographic, reproductive, and lifestyle characteristics. cNMD included spina bifida, cerebral palsy, muscular dystrophy, contractures, or arthrogryposis and were identified by participant report. Those with cNMD were matched to participants without cNMD by interview year and study site. We use modified Poisson regression to estimate relative risks (RR) for low birthweight, macrosomia, preterm birth, and small/large-for-gestational age (SGA/LGA). Given the case-control design and overrepresentation of infants with congenital anomalies, data were weighted to reflect a 3% national prevalence of infants with congenital anomalies.

RESULTS

Mothers with cNMD (n = 125) were more likely to be white, nulliparous, have a cesarean section, have an unplanned pregnancy, report a pre-pregnancy BMI ≥25 kg/m², smoke during pregnancy, and report genitourinary infections. Mothers with cNMD had infants with shorter gestational length (mean difference: -7.44 days, 95% CI: -13.94, -0.95) compared to mothers without cNMD. cNMD was associated with higher risk of preterm birth (RR = 3.98, 95% CI: 1.33, 11.95) and SGA (RR = 2.14, 95% CI: 0.74, 6.15).

CONCLUSION

Mothers with cNMD were more likely to deliver preterm and have an SGA infant. These findings highlight disparities faced by mothers with cNMD and stress the need to provide optimal perinatal and reproductive care.

Associations Between Smoking Status and Physical and Mental Health-Related Quality of Life Among Individuals With Mobility Impairments

BACKGROUND

In the general population, quitting smoking is associated with improved health-related quality of life (QoL), but this association has not been examined in smokers with chronic mobility impairments (MIs).

PURPOSE

We examined associations between smoking status and health-related QoL over 6 months, and whether relationships are moderated by depression and MI severity.

METHODS

This is a secondary analysis of a smoking cessation induction trial among smokers with MIs (n = 241, 56% female, 36% Black) assessed at baseline, and 4 and 6 months after. Participants were grouped into "Smokers" (smoking at 4 and 6 months), "Abstainers" (quit at 4 and 6 months), "Relapsers" (relapsed at 6 months), and "Late-quitters" (quit at 6 months). Physical and mental health-related QoL was assessed with the Short-Form Health Survey. Depression was defined as scores ≥10 on the Patient Health Questionnaire, and MI severity by the use of skilled care for personal needs. Data were analyzed with linear mixed models.

RESULTS

Aggregating across time, among nondepressed participants, compared with "Smokers," the "Abstainer," and "Late-quitter" groups improved their physical health scores. "Late-quitters" also improved compared with "Relapsers." Among the total sample, compared with "Smokers," "Abstainers" showed improvements in mental health scores overtime, whereas "Relapsers" improved their score at 4 months, and "Late-quitters" improved at 6 months.

CONCLUSIONS

Quitting smoking is associated with improvements in physical health-related QoL regardless of the severity of MI but only among those without depression at baseline. For mental health-related QoL, associations with quitting smoking were independent of baseline depression and severity of MI.

A syndemics approach to exercise is medicine

This paper offers new insights into the promotion of the Exercise is Medicine (EIM) framework for mental illness and chronic disease. Utilising the Syndemics Framework, which posits mental health conditions as corollaries of social conditions, we argue that medicalized exercise promotion paradigms both ignore the social conditions that can contribute to mental illness and can contribute to mental illness via discrimination and worsening self-concept based on disability. We first address the ways in which the current EIM framework may be too narrow in scope in considering the impact of social factors as determinants of health. We then consider how this narrow scope in combination with the emphasis on independence and individual prescriptions may serve to reinforce stigma and shame associated with both chronic disease and mental illness. We draw on examples from two distinct research projects, one on exercise interventions for depression and one on exercise interventions for multiple sclerosis (MS), in order to consider ways to improve the approach to exercise promotion for these and other, related populations.

Stigma of persons with disabilities in South Africa: Uncovering pathways from discrimination to depression and low self-esteem

Despite the fact that universal inclusion is a basic principle of the Sustainable Development Goals, the inclusion of persons with disabilities in humanitarian interventions and development policies remains elusive. Persons with disabilities face high risks of poverty, poor nutrition, limited inclusion in labor markets and poor mental health as a result. Stigma is likely to play a negative role in this regard and yet, no study has investigated the impact of stigma on depression and self-esteem of persons with disabilities. To address this gap in the literature, we conducted in June 2017 a random sample disability case control household study in Soweto, a township in Johannesburg, South Africa. Using propensity score analysis and structural equation modeling, we investigated the relationship between disability, stigma, depression and self-esteem controlling for socioeconomic covariates. Our main empirical results showed that stigma significantly mediates the association between disability and higher depression on the one hand and between disability and lower self-esteem on the other. This mediating effect exists even after controlling for age, gender, marital status, education, employment and wealth. We also found strong direct associations between disability and depressive mood, somatic indicators and negative feelings such as unhappiness and low self-esteem. Unemployment aggravates depression and low self-esteem while low education worsens self-esteem only. In addition, depression exacerbates low self-esteem. Both unemployment and low education are more common among persons with disabilities aggravating the disability, depression, poor self-esteem nexus. Similarly, persons with disabilities who are more likely to be depressed are also at higher risk of low self-esteem. These results point to a vicious reinforcing circle of exclusion from society, despair and self-deprecation, which could prove difficult to break. Substantial psycho-social support and anti-stigma policies anchored in local cultural values, engaging persons with disabilities and their communities, are required to break this vicious circle.

The relationship between physical functional limitations, and psychological distress: Considering a possible mediating role of pain, social support and sense of mastery

The aim of this study was to examine associations between selected physical functional limitations related to performing daily activities and psychological distress. We also aimed to investigate if these associations vary across age (moderation), and to explore pain, sense of mastery and social support as potential moderators and mediators. The study was based on pooled data from two rounds (2008 and 2012) of a Norwegian nationally representative cross-sectional health survey (N = 8520) including individuals aged ≥ 16 years (Age groups = 16-44 and ≥ 45 years). Physical functional limitations comprised decreased ability to: i) climb stairs, ii) carry objects, or iii) both. Psychological distress was measured as anxiety and depressive symptoms occurring separately or in combination (CAD). Of respondents reporting physical functional limitations, 8-14% reported depressive symptoms, 5-7% anxiety symptoms, and 13-28% reported CAD. Physical functional limitations were significantly associated with all three forms of psychological distress, particularly among individuals 16-44 years, and were more strongly related to CAD than to anxiety or depression occurring separately. The association with CAD was twice as strong when both types of physical functional limitations were present. Pain, sense of mastery and social support were significant modifiers of depression, whereas all three were significant mediators of the relationship between physical functional limitations and anxiety, depression and CAD. Sense of mastery mediated the relationship between physical functional limitations and CAD, but most strongly among those 16-44 years. Social support was only a significant mediator among those [Formula: see text] 45 years. Close associations between physical functional limitations and psychological distress highlight special needs among individuals experiencing daily functional limitations. The results also suggest that pain, low social support, and low sense of mastery may contribute to aggravate psychological distress.

Using mHealth technologies to improve the identification of behavioral health problems in urban primary care settings

Introduction:

Behavioral health disorders remain under recognized and under diagnosed among urban primary care patients. Screening patients for such problems is widely recommended, yet is challenging to do in a brief primary care encounter, particularly for this socially and medically complex patient population.

Methods:

In 2013, intervention patients at an urban Connecticut primary clinic were screened for post-traumatic stress disorder, depression, and risky drinking (n = 146) using an electronic tablet-based screening tool. Screening data were compared to electronic health record data from control patients (n = 129) to assess differences in the prevalence of behavioral health problems, rates of follow-up care, and the rate of newly identified cases in the intervention group.

Results:

Results from logistic regressions indicated that both groups had similar rates of disorder at baseline. Patients in the intervention group were five times more likely to be identified with depression (p < 0.05). Post-traumatic stress disorder was virtually unrecognized among controls but was observed in 23% of the intervention group (p < 0.001). The vast majority of behavioral health problems identified in the intervention group were new cases. Follow-up rates were significantly higher in the intervention group relative to controls, but were low overall.

Conclusion:

This tablet-based electronic screening tool identified significantly higher rates of behavioral health disorders than have been previously reported for this patient population. Electronic risk screening using patient-reported outcome measures offers an efficient approach to improving the identification of behavioral health problems and improving rates of follow-up care.

Incidence, risk, and associated factors of depression in adults with physical and sensory disabilities: A nationwide population-based study

BACKGROUND

Physical disability has been associated with the risk of depression. We examined the incidence, risk, and associated factors of depression in Taiwanese adults with physical/sensory disabilities.

METHODS

Two national databases were used to retrospectively analyze 749,491 ≥20-year-old Taiwanese with physical/sensory disabilities in 2002-2008. The incidence of depression was analyzed by univariate Poisson regression. Risk factors of depression were followed up through 2014 and examined with a Cox proportional hazards model.

RESULTS

Among the study subjects, the incidence of depression was 6.29 per 1000 person-years, with 1.83 per 1000 person-years corresponding to major depression. The subjects' depression risk was affected by disability type, disability severity, gender, age, education, marital status, aboriginal status, monthly salary, residence urbanization level, and Charlson comorbidity index (CCI). Subjects with rare diseases, mild disability, female gender, age 35-44 years, a high school education level, divorced/widowed status, non-aboriginal status, a NT$22,801-28,800 monthly salary, a highly urbanized residence area, or a CCI≥3 were at higher risk for depression.

CONCLUSIONS AND IMPLICATIONS

Adults with physical/sensory disabilities have a 3.7-fold higher incidence of depression than the general population. Social services departments and family members should take extra measures toward preventing and treating depression in this subpopulation.

Functional Limitation, Pain, and Alcohol Use: Exploring Gender Differences in the Mediating Role of Depressive Symptoms

OBJECTIVE

This study considered the processes linking functional limitation and pain with depressive symptoms and two alcohol-related outcomes (past-month drinking and problematic drinking) over a 3-year period.

METHOD

Data were drawn from a two-wave Miami-Dade County community study of people with physical disabilities (N = 559). Structural equation modeling was used to assess whether depressive symptoms mediated the associations among functional limitation, bodily pain, and the alcohol-related outcomes considered, and whether these associations were moderated by gender.

RESULTS

When the effects of the sociodemographic control variables were controlled for, depressive symptoms partly explained the effects of Wave 1 functional limitation and bodily pain on problematic drinking at Wave 2. The mediating effects of depressive symptoms on problematic drinking were significantly greater for men than for women.

CONCLUSIONS

The findings demonstrate clear linkages between two physical health indicators, depressive symptoms and drinking, and highlight the circumstances in which gender matters most for understanding these associations.

Quality of life in Mexican patients with primary neurological or musculoskeletal disabilities

BACKGROUND

As the population with a disability increases both in number and life expectancy, so does its demand for health services. Very little original research has been done in Mexican populations regarding the effect of disability on quality of life.

OBJECTIVES

1) Assessing the subjective quality of life of patients with neuromusculoskeletal and movement-related function disabilities and, 2) Analyzing the possible effect of the medical condition (diseases of the nervous system vs. diseases of the musculoskeletal system and connective tissue) and its interaction with sex and age.

METHODS

In a cross-sectional design 330 participants were recruited from a public institution in Mexico providing specialized outpatient rehabilitation. After signing informed consent they responded a brief sociodemographic questionnaire and the WHOQOL-BREF scale.

RESULTS

In general quality of life levels were satisfactory. Female and elderly patients with diseases of the nervous system were particularly affected in the physical and psychological dimensions. Women with diseases of the nervous system also showed a negatively affected social quality of life. Elderly with diseases of the musculoskeletal system and connective tissue scored the lowest in general health perception.

CONCLUSIONS

Even though most patients were quite satisfied with their quality of life, not all aspects or cases have such positive perceptions; both the physical and psychological dimensions were particularly negative in female and elderly patients with nervous system diseases. Clinicians would do well to thoughtfully assess patients in these groups and adjust treatment to achieve the greatest possible rehabilitation.

Severity of psychological distress among adults with and without disabilities

The aim of this study is to examine psychological distress and its individual symptoms between adults with and without disabilities, and among adults with disabilities, to examine whether an association exists between severity of distress and health-related factors. Cross-sectional data from the 2007 Behavioral Risk Factor Surveillance System were used for this study. Severity of psychological distress was assessed using the Kessler 6 scale of nonspecific psychological distress. Logistic regression analyses were performed to estimate predicted marginals and prevalence ratios. Nine percent of adults had mild to moderate psychological distress and 3.9% had serious psychological distress. The adjusted mean Kessler 6 total scores and individual item scores were higher for adults with disabilities, as was the average number of days that a mental health condition interfered with activities in the past 30 days. Among adults with disabilities, mild to moderate and serious psychological distress were particularly high among those who were unemployed or unable to work. Those who had either mild to moderate or serious psychological distress were significantly more likely than those with no psychological distress to be physically inactive, to smoke, and to report fair or poor health, life dissatisfaction, and inadequate social support. A dose-response relationship exists between categorical severity of psychological distress and examined health-related factors. These findings may inform the design of targeted public health strategies that aim to eliminate health disparities between people with and without disabilities.

[Importance of secondary conditions in rehabilitation medicine]

The author interprets disability on the basis of the "International Classification of Functioning, Disability and Health (ICF)". In this review the applied method is a purpose oriented, restricted survey of continuously increasing articles published during the last two decades. Definition and interpretation of secondary conditions are based on the cited international classification. It is noted that secondary conditions frequently develop during acute care and usually require rehabilitation. Significance of secondary conditions in rehabilitation is highlighted by selected examples of traumatic spinal cord injury, stroke, lower limb amputation and intellectual disabilities. The author states that there is an insufficiency of presently available knowledge and raises the need for the use of the International Classification of Functioning, Disability and Health as foundation of future research.

Health care access and support for disabled women in Canada: falling short of the UN Convention on the Rights of Persons with Disabilities: a qualitative study

PURPOSE

The United Nations Convention on the Rights of Persons with Disabilities and other international human rights conventions guarantee the fundamental human rights to physical, social, and psychological health. The purpose of this study was to examine whether these rights are being upheld in Canada for disabled women.

METHODS

An interpretive, qualitative, focus group design was employed. Participants were women 18 to 67 years of age with a self-identified physical, sensory, cognitive, and/or psychiatric impairment. Eleven focus groups were conducted with 74 disabled women from urban and rural settings in Northern Ontario, Manitoba, and Nova Scotia. The data were analyzed for themes using a flexible coding system derived from and consistent with the research objectives and the study's human rights framework.

FINDINGS

Participants described multiple intersecting factors that impeded or facilitated access to health care. Services included both generic health services and impairment-specific services. Participants experienced a number of barriers accessing professionals, support programs, and services. These are described under three broad themes: 1) Labyrinthine health service 'systems,' 2) assumptions, attitudes, and discriminatory practices, and 3) inadequate sexual health or reproductive services and supports.

CONCLUSION

The results suggest that Canada falls significantly short of guaranteeing disabled women's human rights to access health care supports and services. Access barriers resulted from the inefficiencies and complexities of the multiple agencies and programs that disabled women had to navigate, difficulties accessing information on available services, and negative attitudes of some health and social service providers.

Organizing future research and intervention efforts on the impact and effects of gender differences on disability and rehabilitation: the usefulness of the International Classification of functioning, Disability and Health (ICF)

The International Classification of Functioning, Disability and Health (ICF) is discussed as being relevant to research and service delivery for women with disabilities. The personal meaning a disability has for a woman is shaped largely by Personal Factors. These, in turn, have historically been affected strongly by Environmental Factors such as culture and attitudes. Too often both Personal Factors, and how they are shaped by Environmental Factors, are not adequately addressed in our intervention programs. The interaction of Personal and Environmental Factors is illustrated by examples from the technology use and non-use literature.
