The heart of Detroit study: a window into urban middle-aged and older African Americans' daily lives to understand psychosocial determinants of cardiovascular disease risk.

BACKGROUND: Cardiovascular disease disproportionately affects African Americans. Psychosocial factors, including the experience of and emotional reactivity to racism and interpersonal stressors, contribute to the etiology and progression of cardiovascular disease through effects on health behaviors, stress-responsive neuroendocrine axes, and immune processes. The full pathway and complexities of these associations remain underexamined in African Americans. The Heart of Detroit Study aims to identify and model the biopsychosocial pathways that influence cardiovascular disease risk in a sample of urban middle-aged and older African American adults. METHODS: The proposed sample will be composed of 500 African American adults between the ages of 55 and 75 from the Detroit urban area. This longitudinal study will consist of two waves of data collection, two years apart. Biomarkers of stress, inflammation, and cardiovascular surrogate endpoints (i.e., heart rate variability and blood pressure) will be collected at each wave. Ecological momentary assessments will characterize momentary and daily experiences of stress, affect, and health behaviors during the first wave. A proposed subsample of 60 individuals will also complete an in-depth qualitative interview to contextualize quantitative results. The central hypothesis of this project is that interpersonal stressors predict poor cardiovascular outcomes, cumulative physiological stress, poor sleep, and inflammation by altering daily affect, daily health behaviors, and daily physiological stress. DISCUSSION: This study will provide insight into the biopsychosocial pathways through which experiences of stress and discrimination increase cardiovascular disease risk over micro and macro time scales among urban African American adults. Its discoveries will guide the design of future contextualized, time-sensitive, and culturally tailored behavioral interventions to reduce racial disparities in cardiovascular disease risk.

Perceived Social Support and Latent Herpesvirus Reactivation: Testing Main and Stress-Buffering Effects in an Ethnically Diverse Sample of Adults.

OBJECTIVE: Perceived social support is consistently associated with physical health outcomes, and one potential physiological mechanism underlying this association is immune function. In this study, we tested both the main and stress-buffering effects of perceived social support on cellular immunity measured via latent herpesvirus reactivation. METHODS: Data were collected from a community-based sample of 1443 ethnically diverse adults between the ages of 25 and 90 years. Participants self-reported measures of perceived social support, stressful life events, daily hassles, and perceived stress, and provided a blood sample to assess antibody titers to the herpes simplex virus type 1 and Epstein-Barr virus (EBV). RESULTS: In accordance with the main effect hypothesis, results indicated that perceived social support was directly associated with EBV viral capsid antigen antibody titers (ß = -0.06, 95% confidence interval = -0.12 to -0.01, p = .029). Perceived social support, however, did not interact with stressful life events, daily hassles, or perceived stress to influence latent herpesvirus reactivation (p values > .05). Neither race/ethnicity nor age moderated any of the interactions between perceived social support and the stress measures on latent herpesvirus reactivation (p values > .10). CONCLUSIONS: Overall, the current study supports the main effect hypothesis, according to which higher levels of perceived social support were associated with lower levels of herpesvirus antibody titers.

Effects of family and neighborhood risks on glycemic control among young black adolescents with type 1 diabetes: Findings from a multi-center study.

While individual and family risk factors that contribute to health disparities in children with type 1 diabetes have been identified, studies on the effects of neighborhood risk factors on glycemic control are limited, particularly in minority samples. This cross-sectional study tested associations between family conflict, neighborhood adversity and glycemic outcomes (HbA1c) in a sample of urban, young Black adolescents with type 1 diabetes(mean age = 13.4 ± 1.7), as well as whether neighborhood adversity moderated the relationship between family conflict and HbA1c. Participants (N = 128) were recruited from five pediatric diabetes clinics in two major metropolitan US cities. Diabetes-related family conflict was measured via self-report questionnaire (Diabetes Family Conflict Scale; DFCS). Neighborhood adversity was calculated at the census block group level based on US census data. Indictors of adversity were used to calculate a neighborhood adversity index (NAI) for each participant. Median family income was $25,000, suggesting a low SES sample. In multiple regression analyses, DFCS and NAI both had significant, independent effects on glycemic control (ß = 0.174, P = 0.034 and ß = 0.226 P = 0.013, respectively) after controlling for child age, family socioeconomic status and insulin management regimen. Tests of effects of the NAI and DFCS interaction on HbA1c found no significant moderating effects of neighborhood adversity. Even within contexts of significant socioeconomic disadvantage, variability in degree of neighborhood adversity predicts diabetes-related health outcomes in young Black adolescents with type 1 diabetes. Providers should assess social determinants of health such as neighborhood resources that may impact adolescents' ability to maintain optimal glycemic control.

Socioeconomic status and differential psychological and immune responses to a human-caused disaster.

OBJECTIVE: Individuals from different socioeconomic status (SES) backgrounds may respond variably to stressful events, and such differences are likely to contribute to health disparities. The current study leveraged data collected before and after a petrochemical explosion and aimed to investigate how individuals from different SES backgrounds responded to this unexpected stressor in terms of perceived social support, perceived stress, and systemic inflammation. METHODS: Data were drawn from 124 participants (Mage = 55.9 ± 16.1 years, 69.4% female, 29.0% White) living close to a petrochemical complex where the explosion occurred in 2005. SES was assessed at baseline, and perceived stress and inflammatory markers (i.e., C-reactive protein [CRP], interleukin-6 [IL-6]) were assessed at both pre- and post-explosion. Perceived social support was assessed at post-explosion. RESULTS: Lower SES was associated with less perceived social support. Lower SES was also associated with a larger increase in perceived stress and higher levels of IL-6, but not CRP. Perceived social support did not moderate or mediate the effects of SES on changes in perceived stress, IL-6, or CRP. The associations between SES and inflammatory markers were also not explained by changes in perceived stress. CONCLUSION: Findings from this study support the idea that individuals from different SES backgrounds respond differently to stressors at both the psychosocial (perceived social support and perceived stress) and biological (inflammation) levels. Our findings also suggest that these two processes appear to act independently from each other.

Process evaluation of the Cancer Home-Life Intervention: What can we learn from it for future intervention studies?

BACKGROUND: The Cancer Home-Life Intervention showed no significant effects, and examination of the processes affecting or inhibiting outcomes is relevant. AIM: To evaluate the Cancer Home-Life Intervention for its processes of implementation, mechanisms of impact and contextual factors. DESIGN: Process evaluation conducted alongside the randomised controlled trial, using quantitative and qualitative methods (ClinicalTrials.gov NCT02356627). The Cancer Home-Life Intervention is a tailored, occupational therapy-based programme. SETTING/PARTICIPANTS: This study took place in participants' homes and at hospital. A total of 113 home-dwelling adults (⩾18 years) with advanced cancer who had received the Cancer Home-Life Intervention were included, together with five intervention-therapists. RESULTS: All 113 participants (100%) received a first home visit; 32 participants (26%) received a second visit; and 4 participants (3%) received a third visit. Median number of delivered intervention components were 3 (interquartile range: 2; 4). Identified barriers for effect included unclear decision process for intervention dosage; participants' low expectations; participants' lack of energy; and insufficient time to adopt new strategies. The trial design constituted a barrier as the intervention could only be provided within a specific short period of time and not when relevant. Intervention components working to solve practical everyday problems, enhance enjoyment and increase a sense of safety were perceived as useful. CONCLUSION: Future interventions can benefit from inclusion criteria closely related to the intervention focus and clear procedures for when to continue, follow-up and terminate intervention. Decisions about dose and timing may benefit from learning theory by taking into account the time and practice needed to acquire new skills.

Development of a Questionnaire to Evaluate Out-of-Home Participation for People With Dementia.

OBJECTIVE: We describe the development of a questionnaire, Participation in Activities and Places Outside Home (ACT-OUT), for older adults with cognitive impairment and align it to people with mild- to moderate-stage dementia. METHOD: ACT-OUT was developed in a cross-cultural collaboration in combination with three rounds of cognitive interviews in Switzerland with 26 older adults without cognitive impairment and five older adults with dementia. Qualitative data from the interviews were analyzed using a constant comparison approach. RESULTS: The final ACT-OUT Version 1.0 consists of three parts: (1) questions targeting places older adults visit; (2) questions on aspects influencing participation, such as transportation, familiarity, and risk perception; and (3) questions on perception of self. CONCLUSION: The development of an instrument such as ACT-OUT is more a cyclical than a linear process. This study is a first step toward a more systematic evaluation of out-of-home participation among older adults with and without dementia.

Changing neighborhoods and occupations: Experiences of older African-Americans in Detroit.

Neighborhood characteristics are relevant to understanding occupations and associated outcomes, yet few empirical studies have focused on neighborhood as the unit of analysis when examining person-environment-occupation relationships. The purpose of this report is to begin addressing that gap. We present findings from a qualitative investigation conducted as part of a larger mixed methods study of 100 African-Americans aged 55 and older living in a variety of neighborhood contexts. With a subsample of older adults (n = 20), we utilized participant-generated photos and photo-elicitation interviews to examine the question of how participation in everyday occupations changes (or not) for older African-Americans residing in urban neighborhoods that have undergone significant physical and socio-demographic changes. Data were analyzed using a thematic analysis approach in combination with a constant comparative method. Occupational change was conceptualized as four primary types: (a) spatio-temporal changes to participation in occupation, (b) changes to social participation, (c) heightened vigilance during daily occupations, and (d) actions to preserve and protect the neighborhood. The findings provide insights about the ways that neighborhood deterioration is related to occupational change. We discuss the potential impact of participants' occupational changes on health and well-being, and we assess the issue of neighborhood and occupation as relevant to occupational justice in urban contexts.

Predicting participation in meaningful activity for older adults with cancer.

PURPOSE: Participation in activity that is personally meaningful leads to improved emotional and physical well-being and quality of life. However, little is known about what predicts participation in meaningful activity by older adults with cancer. METHODS: Seventy-one adults aged 65 years and older with a diagnosis of cancer were enrolled. All adults were evaluated with the following: a brief geriatric assessment, the meaningful activity participation assessment (MAPA), and the Possibilities for Activity Scale (PActS). The MAPA measures participation in meaningful activity, and the PActS measures what older adults believe they should and could be doing. A regression approach was used to assess the predictors of meaningful activity participation. RESULTS: The PActS (B = .56, p < .001) was the strongest predictor of meaningful activity participation. CONCLUSIONS: What older adults with cancer feel they should and could do significantly predicted meaningful participation in activities above and beyond clinical and demographic factors. In future research, perceptions of possibilities for activity may be useful in the design of interventions targeted to improve meaningful participation in older adults with cancer.

The Possibilities for Activity Scale (PActS): Development, validity, and reliability.

BACKGROUND: Laliberte Rudman proposed the concept of occupational possibilities to represent what older adults feel they "should be" and "could be" doing. PURPOSE: This study aimed to develop and validate a measure of perceived occupational possibilities: the Possibilities for Activity Scale (PActS). METHOD: Two factors of the PActS, activity expectations and activity self-efficacy, were operationalized in a 14-item instrument. The instrument was then evaluated with a sample of older adults diagnosed with cancer (n = 179). FINDINGS: The PActS demonstrated promising internal consistency reliability (stratified coefficient α = .77) and construct-related (r = .58; p < .0001), structural (chi-square = 61.57; CFI = .97; RMSEA = .05; TLI = .96; NFL = .91) and known-groups validity. IMPLICATIONS: The PActS appears to be a useful measure of internalized occupational possibilities for participation in activity for older adults with cancer. This scale can enhance the measurement of participation in activity by evaluating the perceptions of occupational possibilities.

Occupational therapy use by older adults with cancer.

Occupational therapy may significantly improve cancer survivors' ability to participate in activities, thereby improving quality of life. Little is known, however, about the use of occupational therapy services by adults with cancer. The objective of this study was to understand what shapes patterns of occupational therapy use to help improve service delivery. We examined older (age >65 yr) adults diagnosed with breast, prostate, lung, or melanoma (skin) cancer between 2004 and 2007 (N = 27,131) using North Carolina Central Cancer Registry data linked to Medicare billing claims. Survivors who used occupational therapy within 1 yr before their cancer diagnosis were more likely to use occupational therapy after diagnosis but also experienced the highest levels of comorbidities. Survivors with Stage 4 cancers or lung cancer were less likely to use occupational therapy. These findings suggest possible disparities in utilization of occupational therapy by older adults with cancer.

Managing Complexity: Black Older Adults With Multimorbidity.

BACKGROUND AND OBJECTIVES: Black older adults have higher rates of multimorbidity and receive less effective multimorbidity support than their white counterparts. Yet little is known about the experiences of Black older adults with multimorbidity that may be at the heart of those disparities and which are central to interventions and improving care for this population. In this study, we aimed to conceptualize the multimorbidity management (MM) experience for Black older adults. RESEARCH DESIGN AND METHODS: As part of a larger study on Black older adults' multimorbidity and physician empathy, we conducted in-depth qualitative interviews with 30 Black older adults living in a large midwestern city in the United States aged 65 years and older with self-reported multimorbidity. We used grounded theory analysis to distill findings into a core conceptual category as well as component domains and dimensions. RESULTS: "Managing complexity" emerged as the core category to describe MM in our sample. Managing complexity included domains of "social context," "daily logistics," "care time," and "care roles." DISCUSSION AND IMPLICATIONS: We discuss how managing complexity is distinct from patient complexity and how it is related to cumulative inequality and precarity. Study findings have potential implications for intervention around provider education and empathy as well as for enabling agency of Black older adults with MM.

Developing community based rehabilitation for cancer survivors: organizing for coordination and coherence in practice.

BACKGROUND: Increasing incidences of cancer combined with prolonged survival have raised the need for developing community based rehabilitation. The objectives of the analysis were to describe and interpret the key issues related to coordination and coherence of community-based cancer rehabilitation in Denmark and to provide insights relevant for other contexts. METHODS: Twenty-seven rehabilitation managers across 15 municipalities in Denmark comprised the sample. The study was designed with a combination of data collection methods including questionnaires, individual interviews, and focus groups. A Grounded Theory approach was used to analyze the data. RESULTS: A lack of shared cultures among health care providers and systems of delivery was a primary barrier to collaboration which was essential for establishing coordination of care. Formal multidisciplinary steering committees, team-based organization, and informal relationships were fundamental for developing coordination and coherence. CONCLUSIONS: Coordination and coherence in community-based rehabilitation relies on increased collaboration, which may best be optimized by use of shared frameworks within and across systems. Results highlight the challenges faced in practical implementation of community rehabilitation and point to possible strategies for its enhancement.

Health Management Occupations During COVID-19: Experiences of Older African Americans With Multimorbidity.

Older African Americans with multimorbidity are at an especially high risk of adverse outcomes due to synergistic risks conferred by age, chronic disease burden and social determinants of health. Chronic condition self-management is one way older African Americans can use health management occupations and exercise agency to reduce their risk of becoming severely ill, and during the ongoing pandemic, of COVID-19 infection. The objective of this study was to understand how the COVID-19 pandemic shaped health management occupations of older African Americans. In-depth qualitative interviews were conducted with 30 African Americans aged 65 and older who reported having two or more chronic conditions. Data were analyzed using thematic analysis. Data suggest how key health management occupations (accessing care; managing medications, nutrition, and physical activity; and social and emotional health promotion and maintenance) were utilized and also shaped by the pandemic. Another key finding was perceived benefits of the pandemic on health and well-being.

Examining Racial/Ethnic Disparities in Coping and Stress Within an Environmental Riskscape.

Existing research on racial/ethnic differences in stress and coping is limited by small samples, single-item measures, and lack of inclusion of Mexican Americans. We address these gaps by analyzing data from the Texas City Stress and Health Study, a cross-sectional sample of Black (N = 257), White (N = 304), US-born (N = 689), and foreign-born (N = 749) Mexican Americans residing in proximity to a petrochemical complex. We compared active and avoidant coping by race/ethnicity and explored multivariable associations between coping and perceived stress. Black and foreign-born Mexican American respondents had the highest stressor exposure yet displayed different patterns of coping and perceived stress patterns. Active coping may be particularly effective for African Americans but may not offset extreme stress disparities. For Mexican Americans, the lack of association between coping and stress underscores the need for more work focused on the culturally diverse coping experiences.

Racial Residential Segregation and the Health of Black Youth With Type 1 Diabetes.

OBJECTIVES: Black youth with type 1 diabetes (T1D) are at heightened risk for suboptimal glycemic control. Studies of neighborhood effects on the health of youth with T1D are limited. The current study investigated the effects of racial residential segregation on the diabetes health of young Black adolescents with T1D. METHODS: A total of 148 participants were recruited from 7 pediatric diabetes clinics in 2 US cities. Racial residential segregation (RRS) was calculated at the census block group level based on US Census data. Diabetes management was measured via self-report questionnaire. Hemoglobin A1c (HbA1c) information was gathered from participants during home-based data collection. Hierarchical linear regression was used to test the effects of RRS while controlling for family income, youth age, insulin delivery method (insulin pump versus syringe therapy), and neighborhood adversity. RESULTS: HbA1c was significantly associated with RRS in bivariate analyses, whereas youth-reported diabetes management was not. In hierarchical regression analyses, whereas family income, age, and insulin delivery method were all significantly associated with HbA1c in model 1, only RRS, age, and insulin delivery method were significantly associated with HbA1c in model 2. Model 2 explained 25% of the variance in HbA1c (P = .001). CONCLUSIONS: RRS was associated with glycemic control in a sample of Black youth with T1D and accounted for variance in HbA1c even after controlling for adverse neighborhood conditions. Policies to reduce residential segregation, along with improved screening for neighborhood-level risk, hold the potential to improve the health of a vulnerable population of youth.

Reactivation of herpes simplex virus type 1 is associated with cytomegalovirus and age.

Recent studies have shown that cytomegalovirus (CMV) may be an emerging marker of immunosenescence. CMV can affect the immune system by directly infecting leukocytes and hematopoietic cells or by eliciting an expansion of oligoclonal CD8+ T cells/contraction of the naïve T cell compartment that may reduce the host's ability to fight other pathogens. To investigate further CMV-associated changes in immunity, a study was conducted with 1,454 adults (ages 25-91) to determine the association between CMV and reactivation of another latent herpesvirus, Herpes simplex virus type 1 (HSV-1), as indexed by antibody titers. Elevated antibody titers to latent HSV-1 were significantly associated with both CMV seropositivity and high CMV antibody levels. Evaluation by specific age groups (<45, 45-64, and 65+ years old) revealed that this association was detectable early in life (<45 years of age). Increases in HSV-1 antibodies by age occurred in CMV seropositive individuals but not CMV seronegative subjects. Within CMV seropositive subjects, increases in HSV-1 antibodies by age were only found in individuals with low CMV antibody levels as those with high CMV antibodies already exhibited elevated HSV-1 antibodies. These associations remained significant after accounting for body mass index, gender, and socioeconomic status. These results suggest that CMV can influence the immune response to another pathogen and support the concept that CMV may accelerate immunosenescence.

Fostering Change Through Occupation-Based Intervention: An International Joint Group Concept Mapping Study.

Further consolidation and clarity regarding occupation as a means to foster change in interventions are needed. The study aimed to utilize the knowledge of occupational scholars to systematically determine what is required to use occupation as means to foster change within occupation-based interventions and to generate a conceptual model from those results. Group Concept Mapping involved the following: preparation, generation of ideas, structuring of statements, data analysis, interpretation of maps, and development of conceptual model. Fifty-two international occupational scholars brainstormed 125 ideas. A cluster rating map with nine clusters posed the foundation for a conceptual model with seven themes, namely, artful use of occupation, evidence-based use of occupation, collaboration to promote occupation, coordinating intervention fit, client factors, sociocultural context, and structural influences. The conceptual model, capturing dimensions and dynamics required for using occupation to foster change, may guide future research into occupation-based interventions.

Social Citizenship Through Out-of-Home Participation Among Older Adults With and Without Dementia.

There is limited empirical knowledge about how older adults living with dementia enact their social citizenship through out-of-home participation. This study aimed: (a) to investigate out-of-home participation among older adults with and without dementia in four countries and (b) to compare aspects of stability or change in out-of-home participation. Using a cross-sectional design, older adults with mild-to-moderate dementia and without dementia, aged 55 years and over, were interviewed using the Participation in ACTivities and Places OUTside the Home questionnaire in Canada (n = 58), Sweden (n = 69), Switzerland (n = 70), and the United Kingdom (n = 128). Data were analyzed using descriptive statistics and a two-way analysis of variance. After adjustment for age, diagnosis of dementia and country of residence had significant effects on total out-of-home participation (p < .01). The results contribute to policies and development of programs to facilitate social citizenship by targeting specific activities and places.

Out-of-home participation among people living with dementia: A study in four countries.

Social participation in out-of-home activities is important for people living with dementia, yet little is known about such participation. The aim of this study was to explore and compare out-of-home participation among people living with dementia in four countries by assessing different types of places of participation visited or no longer visited. A cross-sectional design was used to gather self-reported experiences concerning out-of-home participation among people with mild stage dementia living in Canada (n = 29), Sweden (n = 35), Switzerland (n = 35) and the UK (n = 64). Interviews were conducted using the Participation in ACTivities and places OUTside the Home for older adults (ACT-OUT) instrument. Participants still visited 16 (Median) places out of a possible total of 24, and they had abandoned 5 (Median) places. Neighbourhood was the place most participants still visited, whereas 50% of them had stopped going to a Sports facility, with no significant differences between country samples regarding how many participants had abandoned that place (Fisher's exact test, p > 0.01). There were significant differences between country samples in the frequency of present participation and abandonment of the Hospital, Dentist's office, Cemetery, Garden, and Forest (Fisher's exact test, all p < 0.01). Although the participants still visited a variety of places, they had stopped going to places previously visited, which indicates reductions in participation, posing an inherent risk to well-being. The similarities and differences across samples from the four countries suggest that healthcare services and access to public transport may contribute to the complex interactional process of out-of-home participation for people living with dementia. The findings highlight the need for initiatives targeting specific types of places to support continued participation in society, especially places at a higher risk of abandonment such as places for recreation and physical activity.
