Chronic Disease Among African American Families: A Systematic Scoping Review

Positive Changes in Safety Perception Among Blacks with HIV and Comorbidities: Assessment of Social Determinants of Health During COVID-19

PURPOSE

This study aimed to examine the impact of the COVID-19 lockdown on social determinants of health (SDOH) among Blacks with HIV and a comorbid diagnosis of hypertension or type 2 diabetes mellitus (T2DM).

METHODS

This was a longitudinal survey study. The inclusion criteria were adults ≥ 18 years and the presence of hypertension and/or diabetes, along with a positive HIV diagnosis. This study enrolled patients in the HIV clinics and chain specialty pharmacies in the Dallas-Fort Worth (DFW) area. A survey of ten questions examining SDOH was conducted before, during, and after the lockdown. A proportional odds mixed effects logistic regression model was applied to assess differences between time points.

RESULTS

A total of 27 participants were included. Respondents felt significantly safer in their living place post-lockdown than in the pre-lockdown period (odds ratio = 6.39, 95% CI [1.08-37.73]). No other statistically significant differences in the responses were found over the study timeframe. However, borderline p values indicated better SDOH status post-lockdown as compared to pre-lockdown.

CONCLUSION

Study participants feel safer one year after lockdown compared to pre-lockdown. The CARES Act and the moratorium on rent and mortgage are among the factors that may explain this increase. Future research should include designing and evaluating interventions for social equity enhancement.

Internal consistency reliability of the Revised Illness Perceptions Questionnaire: A systematic review and reliability generalization meta-analysis

The Revised Illness Perception Questionnaire (IPQ-R) assesses patients' perspectives of their illnesses. Original psychometric testing occurred in limited populations. The purpose of this reliability generalization meta-analysis was to: (1) estimate internal consistency reliability of each IPQ-R subscale, and (2) test moderators of these estimates. Web of Science was searched in July 2022 for articles citing the original IPQ-R paper that reported IPQ-R reliability data. Cronbach's alphas (⍺) were pooled for each IPQ-R subscale using inverse variance weighting and DerSimonian and Laird estimation. Sixty-six studies met criteria. Overall pooled ⍺ estimates were acceptable: 0.71-0.87. Treatment control reliability was reduced among cardiac (⍺ = 0.68), diabetes/kidney disease (⍺ = 0.63), and mixed/other (⍺ = 0.66) samples; cyclical reliability was reduced in cancer (⍺ = 0.65) samples. Age, gender, and race were also significant moderators. Subscale reliability varied based on sample characteristics. Adapting IPQ-R subscales to account for sample variation could improve measurement of illness perception constructs.

A review of dairy food intake for improving health among black adults in the US

The adult life stage encompasses a range of new experiences, opportunities, and responsibilities that impact health and well-being. During this life stage, health disparities continue to increase for Black Americans, with Black adults having a disproportionate burden of obesity, chronic diseases, comorbidities, and worse treatment outcomes compared to their White peers. While many of the underlying factors for these disparities can be linked to longstanding sociopolitical factors such as systemic racism, food insecurity, and poor access to healthcare, there are also several modifiable risk factors that are known to significantly impact health outcomes, such as improving diet quality, increasing physical activity, and not smoking. Of all the modifiable risk factors known to impact health, improving dietary habits is the factor most consistently associated with better outcomes for body weight and chronic disease. Of the major food groups recommended by the 2020-2025 Dietary Guidelines for Americans (DGA) for achieving healthier dietary patterns, dairy foods have a nutrient profile which matches most closely to what Black Americans are inadequately consuming (e.g., vitamin A, vitamin D, calcium, magnesium). However, Black adults tend to consume less than half the recommended daily servings of dairy foods, in part, due to issues with lactose intolerance, making higher intake of dairy foods an ideal target for improving diet quality and health in this population. This review examines the current body of evidence exploring the links between dairy intake, obesity, cardiometabolic disease risk, chronic kidney disease, and the most common types of cancer, with a special focus on health and disparities among Black adults. Overall, the evidence from most systematic reviews and/or meta-analyses published in the last decade on dairy intake and health outcomes has been conducted on White populations and largely excluded research on Black populations. The findings from this extensive body of research indicate that when teamed with an energy-restricted diet, meeting or exceeding the DGA recommended 3 daily servings of dairy foods is associated with better body weight and composition outcomes and lower rates of most common chronic diseases than lower intake (<2 servings per day). In addition to the number of daily servings consumed, the specific types (e.g., milk, yogurt, cheese) and subtypes (e.g., low-fat, fermented, fortified) consumed have also been shown to play major roles in how these foods impact health. For example, higher intake of fermented dairy foods (e.g., yogurt) and vitamin D fortified dairy products appear to have the most protective effects for reducing chronic disease risk. Along with lactose-free milk and cheese, yogurt is also generally low in lactose, making it an excellent option for individuals with lactose intolerance, who are trying to meet the DGA recommendations for dairy food intake.

The role of dairy food intake for improving health among black Americans across the life continuum: A summary of the evidence

Decades of health data show major health disparities occurring at every life stage between Black and White Americans. These disparities include greater mortality rates among Black mothers and their offspring, higher levels of malnutrition and obesity among Black children and adolescents, and a higher burden of chronic disease and lower life expectancy for Black adults. Although nutrition is only one of many factors that influence human health and well-being across the life continuum, a growing body of research continues to demonstrate that consuming a healthy dietary pattern is one of the most dominant factors associated with increased longevity, improved mental health, improved immunity, and decreased risk for obesity and chronic disease. Unfortunately, large percentages of Black Americans tend to consume inadequate amounts of several essential nutrients such as vitamin A, vitamin D, calcium, and magnesium; and simultaneously consume excessive amounts of fast foods and sugar-sweetened beverages to a greater degree than other racial/ethnic groups. Therefore, strategies that can help improve dietary patterns for Black Americans could make up a major public health opportunity for reducing nutrition-related diseases and health disparities across the life course. A key intervention strategy to improve diet quality among Black Americans is to focus on increasing the intake of nutrient-rich dairy foods, which are significantly underconsumed by most Black Americans. Compared to other food group, dairy foods are some of the most accessible and affordable sources of essential nutrients like vitamin A, D, and B12, calcium, magnesium, potassium, selenium, and zinc in the food supply, as well as being some of the primary sources of several health-promoting bioactive compounds, including polar lipids, bioactive proteins and peptides, oligosaccharides, and live and active cultures in fermented products. Given the complex relationships that many Black Americans have with dairy foods, due to issues with lactose intolerance, and/or negative perceptions about the health effects of dairy foods, there is still a need to examine the role that dairy foods play in the health and well-being of Black Americans of all ages and life stages. Therefore, the National Medical Association and its partners have produced multiple reports on the value of including adequate dairy in the diet of Black Americans. This present summary paper and its associated series of evidence reviews provide an examination of an immense amount of research focused on dairy intake and health outcomes, with an emphasis on evidence-based strategies for improving the health of Black Americans. Overall, the findings and conclusions from this body of research continue to indicate that higher dairy intake is associated with reduced risk for many of the most commonly occurring deficiencies and diseases impacting each life stage, and that Black Americans would receive significantly greater health benefits by increasing their daily dairy intake levels to meet the national recommendations than they would from continuing to fall short of these recommendations. However, these recommendations must be considered with appropriate context and nuance as the intake of different dairy products can have different impacts on health outcomes. For instance, vitamin D fortified dairy products and fermented dairy products like yogurt - which are low in lactose and rich in live and active cultures - tend to show the greatest benefits for improved health. Importantly, there are significant limitations to these research findings for Black Americans, especially as they relate to reproductive and child health, since most of the research on dairy intake and health has failed to include adequate representation of Black populations or to sufficiently address the role of dairy intake during the most vulnerable life stages, such as pregancy, lactation, fetal development, early childhood, and older age. This population and these life stages require considerably more research and policy attention if health equity is ever to be achieved for Black Americans. Sharing and applying the learnings from this summary paper and its associated series of evidence reviews will help inform and empower nutrition and health practitioners to provide more evidence-based dietary recommendations for improving the health and well-being of Black Americans across the life course.

Mediators of racial disparities in postoperative outcomes among patients undergoing complex surgery

BACKGROUND

This study sought to quantify the direct and indirect effects of race on postoperative outcomes after complex surgery.

METHODS

Medicare patients who underwent abdominal aortic aneurysm (AAA) repair, coronary artery bypass grafting (CABG), lung resection or colectomy were identified (2014-2018). Generalized structural equation modelling was utilized to quantify the direct and indirect effects of race on Textbook outcome (TO).

RESULTS

Among 930,033 patients, 46.8% of patients achieved a TO, with Black patients less likely to achieve a TO (referent: White; Black: OR 0.72, 95% CI 0.70-0.73). Notably, 32.3% of the disparities in TO were attributable to race itself, while 67.7% was explained by other factors. Specifically, residential segregation accounted for 39.4% of the lower TO rates among Black patients, while 21.0% was attributable to a high comorbidity burden.

CONCLUSIONS

These data highlight the need to target structural racism as a policy priority to promote a more equitable healthcare system.

"We need a little strength as well": Examining the social context of informal caregivers for Black women with breast cancer

BACKGROUND

Informal caregivers (e.g., partners, other family members, friends) often provide social support to Black women with breast cancer, and caregivers find both benefits and challenges in their caregiving role.

METHODS

In this qualitative study, twenty-four caregivers for Black women with breast cancer participated in focus groups and interviews. Participants responded to a brief close-ended questionnaire as well as semi-structured questions about their experiences as cancer caregivers. Demographic information was collected, and relationship satisfaction was measured by the Relationship Assessment Scale-General scale (RAS-G). Focus groups and interviews were recorded, transcribed verbatim, and coded by two independent coders. Using an iterative, discussion-based process, the study team developed and refined themes.

RESULTS

All caregivers described themselves as Black/African American, and the majority identified as female (79%). The mean RAS-G score was 4.5 (SD = 0.5), indicating high levels of relationship satisfaction. Qualitative themes included using a range of strategies to provide emotional support; shifting between roles; needing time and space; and trying to stay strong. Several female caregivers described how the cumulative experiences of providing care for multiple family members and friends could be draining, as could their own experiences in the patient role.

CONCLUSIONS

These findings show a complex, multilayered social context that affects both the patient-caregiver relationship and the health and wellbeing of caregivers. Clinicians providing treatment and support for Black women with breast cancer should be mindful of how the health context of the family may affect patient and caregiver outcomes.

Family Health Equity in Chronic Disease Prevention and Management

Introduction/Purpose

Efforts to improve chronic disease outcomes among US adults highlight families, particularly support from families, as a key aspect of disease prevention and management. To date, however, an overwhelming focus on individual-level outcomes and unidirectional support (eg, from a family caregiver to an identified care recipient) belies the existence of co-occurring health concerns and interdependent care. There are increasing calls for more sophisticated and intensive family health interventions that better integrate family-level factors, processes, and outcomes to provide comprehensive family support services in health care and community-based settings.

Methods

This commentary provides key considerations for advancing this work while centering family health equity and families themselves in health initiatives.

Results

Several critical barriers are identified and discussed. For example, a narrow focus on family and inadequate measures of family-level disease burden make it challenging to understand how the disproportionate burden of chronic disease observed among individuals of lower socioeconomic status and certain racial and ethnic groups compounds and complicates family health experiences. In addition, limited attention to the interaction between individuals, families, and broader sociocultural factors that influence family resources and constraints, such as racism, hamper program design, implementation, and evaluation.

Conclusion

To center families in efforts to reduce chronic disease disparities, it is necessary to move beyond superficial attention to the complexity of disease prevention and management within the family context. This commentary serves to enhance understanding of important drivers of family-level chronic disease outcomes, while providing important considerations for advancing research and practice.

Performance of PROMIS Measures to Assess Fatigue and Sleep Symptom Severity Among African American Patients Newly Diagnosed With Obstructive Sleep Apnea

This pilot study examined the concurrent validity of Patient-Reported Outcomes Measurement Information System (PROMIS), Short Form, measures with the longer Multidimensional Fatigue Inventory among patients living with obstructive sleep apnea (OSA). A total of 26 African American patients living with prediabetes and newly diagnosed with OSA completed the six-item short form versions of PROMIS Fatigue and PROMIS Sleep Disturbance, and the longer 20-item Multidimensional Fatigue Inventory. Both PROMIS Fatigue and Sleep Disturbance scales demonstrated high reliability with Cronbach's α of .91 and .92, respectively. PROMIS Fatigue scores were significantly correlated with Multidimensional Fatigue Inventory scores (rs = .53; p = .006) and demonstrated concurrent validity. However, PROMIS Sleep Disturbance scores and Multidimensional Fatigue Inventory scores were not associated with one another. The brief PROMIS Fatigue scale is a useful, succinct approach to assess fatigue severity among diverse patient populations living with OSA. This study is among the first to evaluate the performance of PROMIS Fatigue in a sample living with OSA.

The impact of racially-targeted food marketing and attentional biases on consumption in Black adolescent females with and without obesity: Pilot data from the Black Adolescent & Entertainment (BAE) study

Unhealthy food advertisements ("advertisements" hereafter referred to as "ads") are linked to poor diet and obesity, and food companies disproportionally target Black youth. Little is known about the mechanisms whereby food ads influence diet. One possibility may be racially-targeted ads that appeal to Black youth. Those with food-related attentional biases may be especially vulnerable. The objective of this project was to assess the feasibility and initial effects of a pilot study testing the influence of racially-targeted food ads and food-related attentional biases on eating behaviors among a sample of Black adolescent females. Feasibility of recruitment, retention, and procedures were examined. Participants (N = 41, 12-17y) were randomized to view a television episode clip of the Big Bang Theory embedded with either four 30-second racially-targeted food ads or neutral ads. A computer dot probe task assessed food-related attentional biases. The primary outcome was caloric consumption from a laboratory test meal. Interactions based on weight and ethnic identity were also examined. Analyses of variance and regressions were used to assess main and interaction effects. Exposure to racially-targeted food ads (versus neutral ads) did not affect energy consumption (p > .99). Although not statistically significant, adolescents with obesity consumed nearly 240 kcal more than non-overweight adolescents (p = 0.10). There were no significant preliminary effects related to food-related attentional biases or ethnic identity (ps = 0.22-0.79). Despite a non-significant interaction, these data provide preliminary support that adolescents with obesity may be particularly vulnerable to racially-targeted food ads. An adequately powered trial is necessary to further elucidate the associations among racially-targeted food ads among Black adolescent girls with obesity.

Comparative Evaluation of 2 Work Experience Approaches for Predominantly Black Youth in a Rural Community: Implications for Public Health Workforce Development

CONTEXT

In order to create a more diverse workforce, there is a need to involve historically excluded youth in public health-related work. Youth involvement in asset-based work experience approaches is especially relevant for rural areas with workforce shortages.

OBJECTIVE

To explore the public health workforce development implications of community-based career exploration and asset mapping work experience from the perspective of Black youth.

DESIGN

We used qualitative in-depth interviews with youth, aged 14 to 22 years, who participated in a work experience program anchored in several rural counties in southeastern United States. A phenomenological lens was applied for qualitative analyses with iterative, team-based data coding. Participants were also surveyed pre- and postprogram to supplement findings.

PROGRAM

A rural community-based organization's work experience program consisted of 2 tracks: (1) Youth Connect-a career exploration track that included work placement within community agencies; and (2) MAPSCorps-a track that employs youth to conduct asset mapping for their community.

RESULTS

We interviewed 28 of 31 total participants in the 2 tracks. We uncovered 4 emergent profiles in how youth described shifts in their perceptions of community: (1) Skill Developers; (2) Community Questioners; (3) Community Observers; and (4) Community Enthusiasts. In comparing between tracks, youth who participated in work experience that involved asset mapping uniquely described increased observation and expanded view of community resources and had greater increases in research self-efficacy than youth who participated only in career exploration.

CONCLUSION

Asset mapping work experience that is directly placed in rural communities can expose Black youth to and engage them in essential public health services (assessing and mobilizing community assets) that impact their community. This type of program, directly integrated into rural communities rather than placed near academic centers, could play a role in creating a more diverse public health workforce.

Do Loneliness and Per Capita Income Combine to Increase the Pace of Biological Aging for Black Adults across Late Middle Age?

In a sample of 685 late middle-aged Black adults (M age at 2019 = 57.17 years), we examined the effects of loneliness and per capita income on accelerated aging using a newly developed DNA-methylation based index: the DunedinPACE. First, using linear, mixed effects regression in a growth curve framework, we found that change in DunedinPACE was dependent on age, with a linear model best fitting the data (b = 0.004, p < 0.001), indicating that average pace of change increased among older participants. A quadratic effect was also tested, but was non-significant. Beyond the effect of age, both change in loneliness (b = 0.009, p < 0.05) and change in per capita income (b = -0.016, p < 0.001) were significantly associated with change in DunedinPACE across an 11-year period, accounting for significant between person variability observed in the unconditional model. Including non-self-report indices of smoking and alcohol use did not reduce the association of loneliness or per capita income with DunedinPACE. However, change in smoking was strongly associated with change in DunedinPACE such that those reducing their smoking aged less rapidly than those continuing to smoke. In addition, both loneliness and per capita income were associated with DunedinPACE after controlling for variation in cell-types.

Community-based culturally tailored education programmes for black adults with cardiovascular disease, diabetes, hypertension and stroke: a systematic review protocol of primary empirical studies

INTRODUCTION

Chronic conditions and stroke disproportionately affect black adults in communities all around the world partly due to patterns of systemic racism, disparities in care, and lack of resources. Culturally tailored programmes can potentially meet the needs of the communities they serve, including black adults who may experience reduced access to postacute services. To address unequal care received by black communities, a shift to community-based programmes that deliver culturally tailored programmes may give an alternative to a healthcare model which reinforces health inequities. The objectives of this review are to: (1) synthesise key programme characteristics and outcomes of culturally tailored community-based (CBCT) programmes that are designed to improve health outcomes in black adults with cardiovascular disease, hypertension, diabetes, or stroke and (2) identify which of the five categories of culturally appropriate programmes from Kreuter and colleagues have been used to implement CBCT programmes.

METHODS AND ANALYSIS

This is a protocol for a systematic review that will search Medline, Embase and Cumulative Index to Nursing and Allied Health Literature databases to identify studies of CBCT programmes for black adults with cardiovascular disease, hypertension, diabetes, or stroke between 2000 and 2021. Two reviewers will assess each study based on the inclusion criteria and any disagreements will be resolved by a third reviewer. Data will be extracted using a customised data extraction form to identify programme characteristics and the strategies used to develop culturally appropriate programmes. AMSTAR will be used to evaluate the articles included in the study. The aggregated data will be presented through textual descriptions of programme characteristics and outcomes.

ETHICS AND DISSEMINATION

This systematic review protocol does not require ethics approval without the inclusion of human participants and will use studies that have previously obtained informed consent. The systematic review findings will be disseminated in a peer-reviewed journal and used to inform future research led by JF and HS.

Physical activity and sedentary behaviour interventions for people living with both frailty and multiple long-term conditions: a scoping review protocol

INTRODUCTION

The number of people living with multiple long-term conditions (MLTCs) is predicted to rise. Within this population, those also living with frailty are particularly vulnerable to poor outcomes, including decreased function. Increased physical activity, including exercise, has the potential to improve function in those living with both MLTCs and frailty but, to date, the focus has remained on older people and may not reflect outcomes for the growing number of younger people living with MLTCs and frailty. For those with higher burdens of frailty and MLTCs, physical activity may be challenging. Tailoring physical activity in response to symptoms and periods of ill-health, involving family and reducing sedentary behaviour may be important in this population. How the tailoring of interventions has been approached within existing studies is currently unclear. This scoping review aims to map the available evidence regarding these interventions in people living with both frailty and MLTCs.

METHODS AND ANALYSIS

We will use a six-stage process: (1) identifying the research questions; (2) identifying relevant studies (via database searches); (3) selecting studies; (4) charting the data; (5) collating and summarising and (6) stakeholder consultation. Studies will be critically appraised using the Mixed Methods Appraisal Tool.

ETHICS AND DISSEMINATION

All data in this project will be gathered through database searches. Stakeholder consultation will be undertaken with an established patient and public involvement group. We will disseminate our findings via social media, publication and engagement meetings.

A systematic scoping review of post-treatment lifestyle interventions for adult cancer survivors and family members

PURPOSE

Supporting the health of cancer survivors and their families from diagnosis through survivorship is a recognized priority. However, the extent to which health promotion efforts after the completion of acute treatment attend to the needs of adult survivors and families is unclear. This systematic scoping review summarizes the key characteristics of post-treatment lifestyle interventions aiming to improve diet, physical activity, and/or weight-related outcomes for adult cancer survivors and family members.

METHODS

We retrieved relevant studies from six databases using keywords. Studies were appraised for quality and limited to English-language, peer-reviewed journal articles published in or after 2005.

RESULTS

A total of 2,376 articles were obtained from the databases; 14 main articles (and 2 supplemental articles) representing 14 unique interventions were retained for our analysis. Most interventions were designed to modify aspects of participant diet and physical activity (in combination) or physical activity alone; cited social cognitive theory as a guiding or interpretative framework; included survivors of multiple cancer types; and were limited to one type of familial relationship (e.g., spouse/partner, sister). Where reported, intervention samples were predominantly White.

CONCLUSIONS

Few post-treatment interventions concurrently target cancer survivor and family members' positive lifestyle behaviors. Positive findings highlight the potential for expanding this area of intervention research and increasing understanding of individual and familial factors that contribute to successful post-treatment family interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Promoting cancer survivors' healthy behaviors within the family context could capitalize on existing support networks and improve the health of family members in supportive roles.

Predictors of Polypharmacy Among Elderly Patients in China: The Role of Decision Involvement, Depression, and Taking Chinese Medicine Behavior

Introduction: The prevalence of polypharmacy is gradually increasing in geriatrics, which may contribute to adverse effects, such as potential drug-drug and drug-disease interactions. These side effects remain an important challenge in patient safety, which has a significant impact on mortality and incidence rate. Aims: Therefore, this study aims to understand the epidemiology of polypharmacy and identify factors that have an impact on the management of potentially inappropriate prescribing. Methods: This study is a cross-sectional study, analyzing the prescription data from 720 hospitalized patients aged 50+ with a random cluster sampling method. We used inverse probability treatment weighting (IPTW) method to group and match polypharmacy and non-polypharmacy patients, and logistic regression was conducted to explore the factors associated with polypharmacy. Results: The prevalence of polypharmacy accounted for 50.14% among the old patients in this study. Female patients (67.34%) have more polypharmacy than male patients, and key predictors associated with polypharmacy in the logistic regression model included the following: domicile (AOR = 0.63, 95% CI 0.42-0.95), annual income (AOR = 0.38, 95% CI 0.20-0.70), the number of chronic diseases (AOR = 3.68, 95% CI 2.69-5.06), taking Chinese medicine (AOR = 1.70, 95% CI 1.22-2.36), decision involvement (AOR = 1.49 95% CI 1.10-2.03), and depression (AOR = 1.42, 95% CI 1.03-1.96). Conclusion: Polypharmacy is common among the participants with chronic diseases in Hubei province, China. The study emphasizes that gerontology practitioners should be prudent in applying clinical guidelines to provide personalized, comprehensive assessment of decision making of prescriptions, especially in socioeconomically deprived areas.

Applicability of Pharmacogenomically Guided Medication Treatment during Hospitalization of At-Risk Minority Patients

Known disparities exist in the availability of pharmacogenomic information for minority populations, amplifying uncertainty around clinical utility for these groups. We conducted a multi-site inpatient pharmacogenomic implementation program among self-identified African-Americans (AA; n = 135) with numerous rehospitalizations (n = 341) from 2017 to 2020 (NIH-funded ACCOuNT project/clinicaltrials.gov#NCT03225820). We evaluated the point-of-care availability of patient pharmacogenomic results to healthcare providers via an electronic clinical decision support tool. Among newly added medications during hospitalizations and at discharge, we examined the most frequently utilized medications with associated pharmacogenomic results. The population was predominantly female (61%) with a mean age of 53 years (range 19-86). On average, six medications were newly prescribed during each individual hospital admission. For 48% of all hospitalizations, clinical pharmacogenomic information was applicable to at least one newly prescribed medication. Most results indicated genomic favorability, although nearly 29% of newly prescribed medications indicated increased genomic caution (increase in toxicity risk/suboptimal response). More than one of every five medications prescribed to AA patients at hospital discharge were associated with cautionary pharmacogenomic results (most commonly pantoprazole/suboptimal antacid effect). Notably, high-risk pharmacogenomic results (genomic contraindication) were exceedingly rare. We conclude that the applicability of pharmacogenomic information during hospitalizations for vulnerable populations at-risk for experiencing health disparities is substantial and warrants continued prospective investigation.

Symptom distress and quality of life among Black Americans with cancer and their family caregivers

OBJECTIVE

Black Americans are disproportionately affected by cancer and chronic diseases. Black patients with cancer and their family caregivers may concurrently experience symptoms that influence their wellbeing. This study investigates the influence of mental and physical symptom distress on quality of life (QOL) among Black Americans with cancer and their family caregivers from a dyadic perspective.

METHODS

One hundred and fifty-one dyads comprised of a Black American with breast, colorectal, lung or prostate cancer and a Black family caregiver were included in this secondary analysis of pooled baseline data from three studies. Self-reports of problems managing 13 symptoms were used to measure mental and physical symptom distress. Descriptive statistics and the actor-partner interdependence model were used to examine symptom prevalence and the influence of each person's symptom distress on their own and each other's QOL.

RESULTS

Fatigue, sleep problems, pain and mental distress were prevalent. Patients and caregivers reported similar levels of mental distress; however, patients reported higher physical distress. Increased patient mental distress was associated with decreased patient QOL (overall, emotional, social, functional). Increased patient physical distress was associated with decreased patient QOL (overall, physical, emotional, functional) and decreased caregiver emotional wellbeing. Increased caregiver mental distress was associated with decreased caregiver QOL (overall, emotional, social, functional) and decreased patient overall QOL. Increased caregiver physical distress was associated with decreased caregiver QOL (overall, physical, functional), decreased patient emotional wellbeing, and better patient social wellbeing.

CONCLUSIONS

Supporting symptom management in Black patient/caregiver dyads may improve their QOL.
