Racial and Ethnic Disparities in Chronic Stress among Male Caregivers.

Whereas research on caregiving is well documented, less is known about gender inequalities in caregiver stress, coping mechanisms, and health outcomes, all of which may vary by race, ethnicity, and socioeconomic status. This scoping review investigated racial and ethnic disparities using the Stress Process Model among male caregivers. Several databases were searched including Academic Search Premier, Medline Complete, APA PsycInfo, CINHAL, Google, ProQuest, and Web of Science. Included were peer-reviewed articles in English, published from 1990 to 2022. A total of nine articles fulfilled inclusion criteria. Most of the articles indicated that compared to White male caregivers, African American male caregivers provided more hours of care, assisted with more activities of daily living (ADLs) and instrumental activities of daily living (IADLs), and experienced more financial stress. In terms of coping style, one study found African American male caregivers, compared to White male caregivers, held negative religious beliefs. Another study showed that they were at a higher risk for stroke than their White counterparts. The search revealed a dearth of studies on racial disparities in stress, coping, and health outcomes among male caregivers. Further research is needed on the experiences and perspectives of male minority caregivers.

The Socialization of Unpaid Family Caregivers: A Scoping Review.

As unpaid family caregiving of older adults becomes increasingly prevalent, it is imperative to understand how family caregivers are socialized and how they understand the caregiving role. This PRISMA-ScR-based scoping review examines the published literature between 1995-2019 on the socialization of potential and current unpaid family caregivers of older adults. Of 4,599 publications identified, 47 were included. Three perspectives of socialization were identified: (1) role acculturation; (2) role negotiation and identification; and (3) specialized role learning. The findings show how socialization involves different contexts (e.g., cultures), imperatives for action (e.g., circumstances), socialization agents (e.g., family), processes (e.g., modeling), and internal (e.g., normalization) and external (e.g., identification) consequences for caregivers. Future research could fruitfully explore how caregivers manage key turning points within the socialization process, disengage from the caregiving role, and negotiate the socialization and individualization processes within diverse cultural and funding contexts.

Correlates of Strength and Balance Training Exercises in Older African American Adults.

BACKGROUND AND OBJECTIVES: This study investigated the behavioral and psychological correlates of strength and balance training (SBT) participation among older African Americans. RESEARCH DESIGN AND METHODS: A cross-sectional survey of 90 older African Americans (M = 66.7 ± 8.7 years; 70% female) was conducted to assess correlates of intention to undertake SBT exercises and the number of days that they currently engage in SBT. The Theory of Planned Behavior (TPB) and the threat appraisal of the Protection Motivation Theory (PMT) were used as frameworks for the analyses. RESULTS: The intention to do SBT exercises was positively associated with favorable attitudes and subjective norm, knowledge about the benefits of SBT, and hours worked per week. The frequency of SBT participation was significantly correlated with behavioral intention, high fear of falling, and a low score on the kinesiophobia scale. DISCUSSION AND IMPLICATIONS: This study demonstrated the utility of the TPB and PMT's threat appraisal construct in modeling intention and number of days of SBT participation among African American older adults. The study affirmed the link between intention and behavior and between knowledge of the benefits of SBT and intention. Fear of falling's positive association with days of SBT suggests that respondents' saw SBT's efficacy in reducing falls. The unique contributions of this study are the inclusions of kinesiophobia as a correlate and multiple threat appraisals in the PMT. Health promotion interventions should consider the interrelationship among these constructs.

Uncertainty in Transition of African American Caregivers.

The purpose of this study was to gain an understanding of the ambiguities and uncertainties experienced by a diverse group of African-American caregivers. The study applied Schlossberg's transition theory (TT) and Mishel's revised uncertainty theory to narratives of self-identified African-American caregivers who provided care at least 5 h a week. The men (6) and women (8) were mostly unmarried, mostly caring for a parent or grandparent. The caregivers' average age was 52 (SD = 19; ages ranged from 24 to 82 years); and the care recipients' average age was 84 (SD = 9). Six care recipients had dementia and the remainder had multiple disease diagnoses. Narratives were obtained by in-depth interviews or focus group discussions. These were audio-recorded, transcribed verbatim professionally and analyzed independently by trained coders. Schlossberg's TT contextualized whereas Mishel's RUIT illuminated the characteristics of the transition, its associated uncertainty, and their relationship to the development of caregiver stress. Situational factors such as difficulties with illness symptoms of the care recipient, conflict between previous experience and current expectations and the adjustments to the new caregiving role, burdened younger caregivers more than older caregivers. Self-factors related to lack of knowledge about the illness and feelings of lack of control. Social support was predominantly provided by family members, and its absence resulted in conflict among siblings and caregiver stress. The most common coping strategies include religiosity, expectations of reciprocity, and coming to terms with the uncertainty. Understanding the feelings, perceptions and needs of caregivers in transition is tantamount to providing nursing care.

Dementia and Caregiver Stress: An Application of the Reconceptualized Uncertainty in Illness Theory.

The Reconceptualized Uncertainty in Illness Theory (RUIT) was used to investigate antecedents to, appraisals of, and ways of coping with stressful caregiving. Four focus groups with caregivers (8 males and 16 females) of relatives with dementia were conducted; 15 cared for their parents and the remainder cared for their spouses. They were recruited from an adult care center and other community settings in a metropolitan area in New England. The discussions were audiotaped and transcribed verbatim. Two researchers independently coded the transcripts. Thematic analysis was structured according to the RUIT. The study is unique in its application to caregivers as opposed to patients and to all of the elements of the RUIT. Caregivers experience uncertainty in similar ways to patients with life-altering illness. Symptom severity--lack of personal boundaries, repetitive and aggressive behaviors, and the need for constant care--was the most frequent source of stress. The appraisals were mostly negative and included feelings of resentment, a lack of support from family members, financial strains, and loss of freedom. Self-improvement and self-care were important aspects of coping. Spirituality and humor were other coping skills that respondents used. Not all respondents said they were coping and some also reported that support from health care providers was not always helpful. Nurses can help improve coping by explaining the factors that contribute to caregiver strain and uncertainty, and by assisting caregivers to anticipate the effects of the caregiving role.

Recruitment and retention of healthy and high-risk older adults for a multiyear influenza vaccination study.

PURPOSE: Evaluate five different recruitment strategies for their capacity to enroll and retain both healthy and vulnerable older adults as part of a multiyear influenza vaccination study. METHODS: We analyzed recruitment methods and other characteristics ofindividuals who participated in or were considered for five sequential one-year studies. RESULTS: Of 940 screened individuals, 820 met eligibility criteria with 795 enrolled over the five-year study (307 primary participants). Among these enrollees, 63.4% were female and 95.5% were white, with mean ages of 75.3 (older group) and 30.6 (younger group). More than a half (56.7%) of the participants enrolled more than once, participating an average of 2.56 (SD = 1.6) times. The majority (81.9%) of individuals recruited each year were return participants identified during earlier recruitments. Physician referrals resulted in only 5.3% recruitments. CONCLUSIONS: Recruitment and retention of study subjects, especially older adults, was facilitated by the existence ofa database listing past participants.

Insights into the experiences of older workers and change: through the lens of selection, optimization, and compensation.

PURPOSE: The study examined the barriers faced, the goals selected, and the optimization and compensation strategies of older workers in relation to career change. METHOD: Thirty open-ended interviews, 12 in the United States and 18 in New Zealand, were conducted, recorded, transcribed verbatim, and analyzed for themes. RESULTS: Barriers to finding and maintaining work included task difficulty, problems with coworkers and management, lack of self-confidence, health/physical limitations, ageism, and stereotyping. Respondents' most frequently selected goals for a new career were the desire to help others, work satisfaction, and acquisition of learning. Seventy-five percent of respondents in paid employment had earning an income as a goal. Optimization strategies included drawing on past experience, assessing skills, seeking careers/organizations that fitted their values, and a willingness to accept lower pay or unpaid work. Attitudinal strategies included focus and persistence, optimism, and positive attitudes toward change. The compensation strategies reported were on-the-job training; help from coworkers, clients, or customers; friends and family social support; and professional networks. Management practices considered helpful were flexible work schedules, supervisors' patience, and formal recognition of the value of older workers. CONCLUSION: This qualitative study, using the SOC framework, showed that evaluating one's skills and values, being positive about change, and being part of a supportive work environment were key contributors to adaptive competence.

Adherence to calcium/vitamin D and estrogen protocols among diverse older participants enrolled in a clinical trial.

PURPOSE: This study was intended to identify characteristics of those who adhere poorly to calcium/vitamin D and estrogen replacement protocols, and aimed to assess the effects of ethnicity, socio-economic status, and health status on medication adherence. METHODS: The adherence rates of 107 older white, African American and Hispanic participants of a clinical trial involving calcium/vitamin D and either estrogen replacement or placebo therapy were analyzed. Structural equation modeling was used to test the hypothesis that minority participants would have lower adherence rates than white participants, but only if they had lower household incomes and educational achievement, more osteoporosis risk factors, negative health assessments, and fewer somatic complaints than white participants. RESULTS: The average age of participants was 76 years. Minority participants and those with lower SES had lower adherence rates than white participants and those with higher SES. Plausible models that met goodness-of-fit criteria showed that the estrogen/placebo adherence rates were affected directly by being African American or Hispanic and the SF-36 mental health score, and indirectly by somatic complaints. History of fracture and household income directly predicted calcium/vitamin D adherence rates. CONCLUSION: Efforts to improve adherence to medical regimens should consider differences in adherence behaviors based on ethnicity, SES, and mental health.

Osteoporosis medications used by older African-American women: effects of socioeconomic status and psychosocial factors.

This study examined the effects of socioeconomic status, knowledge and Health Belief Model variables on ever use of hormone therapy and other osteoporosis medications among older African-American women. One-hundred and two African-American women, 60 years old or older, randomly selected from Registers of Voters and a list of participants in educational activities of a university hospital, were interviewed in their homes. Data collected concerned knowledge of osteoporosis, Health Belief Model variables, and cues to action such as history of hysterectomy, personal and family history of cancer, bone mineral density testing, and discussion with a physician about osteoporosis. Socioeconomic status indicators included years of education and household income. The average respondent age was 71.1 years; 47% were current or previous users (ever users) of hormone therapy, and 11% were ever users of other osteoporosis medications. Knowledge of osteoporosis, (odds ratio = 1.4), Hormone therapy benefits, (odds ratio = 1.63), a hysterectomy (odds ratio = 4.35), and a family history of cancer (odds ratio = 4.0) increased the odds of ever using hormone therapy. Perceptions of susceptibility (odds ratio = 3.5) and discussion with a physician about osteoporosis (odds ratio = 6.4) increased odds of ever using other osteoporosis medications. Socioeconomic status mediated the effects of knowledge of osteoporosis on ever using hormone therapy. Efforts to promote bone health to older African-American women should focus primary efforts to increasing perceptions of susceptibility to fracture and persuading physicians to initiate discussions about fracture prevention with African-American patients before a fracture occurs.

The effect of different doses of micronized 17beta-estradiol on C-reactive protein, interleukin-6, and lipids in older women.

BACKGROUND: The authors evaluated the effect of 3 doses (0.25 mg/day, 0.5 mg/day, and 1 mg/day) of micronized 17beta-estradiol (E2) on C-reactive protein (CRP), interleukin-6 (IL-6), and lipids, compared with placebo, in healthy older women participating in an osteoporosis study. METHODS: This randomized, double-blind, placebo-controlled study was conducted in a University clinical research center. Participants were healthy, community-living women older than 65 years. The primary outcome measure of the study was bone metabolism as estimated by serum and urine markers of bone turnover. For this analysis, the authors measured serum markers of CRP, IL-6, lipids, intracellular adhesion molecule-1, and E-selectin at baseline, after 12 weeks of treatment, and after 12 weeks with no treatment. RESULTS: A significant dose-response effect of estrogen occurred on CRP levels. After 12 weeks of treatment, CRP decreased 59% in the 0.25 mg/day E2 group and increased 65% in the 1 mg/day E2 group, compared with placebo. The CRP level continued to be elevated (92%), compared with placebo, 12 weeks after treatment was discontinued in the 1 mg/day E2 group. High-density lipoprotein (HDL) and HDL2 cholesterol increased and low-density lipoprotein (LDL) cholesterol decreased at 12 weeks in the 1 mg/day E2 group, with a significant dose-response effect. E-selectin decreased significantly in the 1 mg/day E2 group 12 weeks after discontinuation of treatment (-7%), and there was a significant dose-response effect at this time. The 2 lower doses did not affect any of these parameters. Total and HDL3 cholesterol, triglycerides, lipoprotein(a), intracellular adhesion molecule-1, and IL-6 did not change with any dose of E2. CONCLUSIONS: C-reactive protein, an inflammation marker associated with increased risk for cardiovascular disease, decreased in women taking the lowest estrogen dose but increased in women assigned to the highest estrogen dose, suggesting decreased inflammation with lower dose E2. However, with 3 months of treatment, 0.25 or 0.5 mg/day E2 did not have the same beneficial effects on HDL or LDL cholesterol as did 1 mg/day E2. These data suggest that estradiol doses have differential short-term effects on markers of cardiovascular disease. Low-dose E2 decreased CRP, an important marker of inflammation, but did not affect lipid parameters, whereas the highest dose increased CRP and had a beneficial effect on lipid parameters. The long-term consequences of these effects are unknown, but it is possible that estradiol dose should be considered when risk:benefit ratios are evaluated for individual women before estrogen replacement therapy is initiated.

Strategies for enrolling diverse older women in an osteoporosis trial.

OBJECTIVES: This study reviewed a consumer-oriented process for recruiting research volunteers age 65 or older for an osteoporosis clinical trial. METHODS: Odds ratios were used to estimate the relative importance of methods to enroll research volunteers from three racial or ethnic groups. RESULTS: Nine hundred and four women were screened; 168 African American, White, and Hispanic women enrolled. Mailings and media were effective when the target population was large and knowledgeable about the disease and treatment being investigated. Efficiency of mailings was increased when individuals in the mailing list were familiar with research and the research center. An interpersonal approach was more effective than a media-based approach when the target population was small, unaware of their personal risk of the disease, and unfamiliar with research and research center. DISCUSSION: Information on the characteristics of potential volunteers and their communities will enable readers to evaluate the applicability of recruitment methods used.

Barriers to eligibility and enrollment among older women in a clinical trial on osteoporosis: effects of ethnicity and SES.

OBJECTIVES: The study examined whether ethnicity or socioeconomic status influenced a group's ability to meet eligibility criteria and willingness to enroll. METHOD: The eligibility and enrollment status of 904 women aged 65 years and older who responded to recruitment efforts of an estrogen and osteoporosis clinical trial were analyzed. RESULTS: Among women screened, 59% were White, 27% African Americans, and 14% Hispanics; average age was 75 years; 57.6% were eligible, of which 32% enrolled. High-income area residents were more likely to be eligible than low-income residents. African Americans were less likely to be eligible for medical reasons than non-African Americans. Eligible Hispanics were more likely to be enrolled than non-Hispanics. African Americans were equally willing to enroll as Whites. Minority residents of low-income areas were more likely to enroll than minority residents of high-income areas. DISCUSSION: Recruitment efforts should address barriers to eligibility and barriers to willingness to enroll.

Effects of smoking cessation or reduction on hormone profiles and bone turnover in postmenopausal women.

The purpose of this study was to prospectively evaluate the impact of smoking cessation on hormonal concentrations, sex hormone-binding globulin (SHBG) and markers of bone turnover in postmenopausal women. Sixty-six women who were either users or non-users of estrogen replacement therapy (ERT) were randomly assigned, using a weighted randomization scheme, to smoking cessation (SC) or to smoking cessation after 6 weeks of monitoring (wait-list control group, WLC). We measured hormones [estrone, estradiol, testosterone, parathyroid hormone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS) and androstenedione] and SHBG, markers of bone turnover [procollagen peptide (PINP), bone alkaline phosphatase (BAP), and osteocalcin (OC), N- and C-terminal collagen cross-links (NTx and CTx)], and cotinine, at baseline and again at 6 weeks in women who reported smoking cessation and in women randomized to the WLC group. Analyses included 20 subjects who quit or significantly reduced their smoking and 18 subjects in the WLC group. After controlling for differences in age and ERT use between groups, we found a significant change in SHBG in the SC vs. the WLC group (-8% vs. +5%, respectively; p = 0.01), and in DHEA (-18% vs. -5%, respectively; p = 0.04), but not in other hormonal concentrations. We also noted a significant change in NTx in the SC vs. WLC group (-5% vs. +56%, respectively, p = 0.01), but not in other markers of bone turnover. Percentage changes in SHBG and NTx were correlated with changes in plasma cotinine (r = 0.48; p = 0.004 and r = 0.36; p = 0.04, respectively). Six weeks of smoking abstinence produces reductions in SHBG and NTx. This may partly explain how smoking contributes to osteoporosis in postmenopausal women.
