Inequalities in dementia incidence between six racial and ethnic groups over 14 years.

ABSTRACT: Reducing racial/ethnic disparities is a primary objective of the National Alzheimer's Plan (NAPA), yet direct comparisons within large samples representing diversity of the United States are lacking.Dementia incidence from January 1, 2000 to December 31, 2013 and a 25-year cumulative risk in 274,283 health care members aged 64+ (n = 18,778 African-American, n = 4543 American Indian/Alaska Native [AIAN], n = 21,000 Latino, n = 440 Pacific Islander, n = 206,490 white, n = 23,032 Asian-Americans). Cox proportional hazard models were adjusted for age, sex, medical utilization, and comorbidities.Dementia incidence (n = 59,555) was highest for African-Americans (26.6/1000 person-years) and AIANs (22.2/1000 person-years); intermediate for Latinos (19.6/1000 person-years), Pacific Islanders (19.6/1000 person-years), and whites (19.3/1000 person-years) and lowest among Asian-Americans (15.2/1000 person-years). Risk was 65% greater for African-Americans (hazard ratio = 1.65; 95% confidence interval = 1.58-1.72) versus Asian-Americans. Cumulative 25-year risk at age 65 was as follows: 38% African-Americans, 35% AIANs, 32% Latino, 25% Pacific Islanders, 30% white, and 28% Asian-Americans.Dementia rates varied over 60% between groups, providing a comprehensive benchmark for the NAPA goal of reducing disparities.

Project description:BackgroundCertain racial/ethnic minority groups have a higher risk of developing dementia, yet studies have demonstrated that they often have limited knowledge and understanding of this disease. An increasing number of educational and advocacy programs have been developed to promote dementia knowledge. We aimed at assessing current evidence and quality regarding educational interventions for promoting dementia knowledge.MethodsWe searched for intervention studies published in English that focused on educational interventions for promoting dementia knowledge among racial/ethnic minority groups. We identified 25 relevant studies through PubMed, PsycINFO, CINAHL, and Scopus, using tailored search terms. We screened titles and abstracts, reviewed full texts, synthesized relevant evidence, and evaluated the studies' quality based on the Mixed Methods Appraisal Tool. Relevant intervention studies took place in communities, hospitals or clinics, and schools, and online.ResultsMost studies were conducted in the United States (n = 21), followed by the UK (n = 3). Over half of the studies included Asian/Pacific Islander groups (n = 14), followed by Black groups (n = 12) and Hispanic groups (n = 11). The intervention delivery mode varied across studies-from workshops hosted in a faith community to talk shows on YouTube. Target populations included middle-aged and older adults, caregivers and family members, health students and professionals, and elementary school students. Common content included symptoms and signs of dementia, protective and risk factors, and local resources. The assessment of study outcomes varied across studies. Improvement in dementia knowledge and attitudes towards dementia was reported in many studies. Among the included studies, intervention satisfaction was high. The overall quality of the interventions was low.ConclusionFormally evaluated educational interventions promoting dementia knowledge are at an early stage. Existing published interventions showed adequate acceptability and promise in promoting better understanding and awareness of dementia in minority groups. More well-designed randomized controlled trials are needed.

Project description:BACKGROUND:Caring for a family member with dementia is extremely stressful, contributes to psychiatric and physical illness among caregivers, and increases the risk for caregiver death. Finding better ways to support family caregivers is a major public health challenge. OBJECTIVE:To test the effects of a structured multicomponent intervention on quality of life and clinical depression in caregivers and on rates of institutional placement of care recipients in 3 diverse racial or ethnic groups. DESIGN:Randomized, controlled trial. SETTING:In-home caregivers in 5 U.S. cities. PARTICIPANTS:212 Hispanic or Latino, 219 white or Caucasian, and 211 black or African-American caregivers and their care recipients with Alzheimer disease or related disorders. INTERVENTION:Caregivers within each racial or ethnic group were randomly assigned to an intervention or to a control group. The intervention addressed caregiver depression, burden, self-care, and social support and care recipient problem behaviors through 12 in-home and telephone sessions over 6 months. Caregivers in the control group received 2 brief "check-in" telephone calls during the 6-month intervention. MEASUREMENTS:The primary outcome was a quality-of-life indicator comprising measures of 6-month caregiver depression, burden, self-care, and social support and care recipient problem behaviors. Secondary outcomes were caregiver clinical depression and institutional placement of the care recipient at 6 months. RESULTS:Hispanic or Latino and white or Caucasian caregivers in the intervention group experienced significantly greater improvement in quality of life than those in the control group (P < 0.001 and P = 0.037, respectively). Black or African-American spouse caregivers also improved significantly more (P = 0.003). Prevalence of clinical depression was lower among caregivers in the intervention group (12.6% vs. 22.7%; P = 0.001). There were no statistically significant differences in institutionalization at 6 months. LIMITATIONS:The study used only a single 6-month follow-up assessment, combined heterogeneous cultures and ethnicities into a single group, and excluded some ethnic groups. CONCLUSIONS:A structured multicomponent intervention adapted to individual risk profiles can increase the quality of life of ethnically diverse dementia caregivers.

Project description:ObjectivesTo examine racial and ethnic differences in knowledge about one's dementia status.DesignProspective cohort study.SettingThe 2000 to 2014 Health and Retirement Study.ParticipantsOur sample included 8,686 person-wave observations representing 4,065 unique survey participants, aged 70 years or older, with dementia, as identified by a well-validated statistical prediction model based on individual demographic and clinical characteristics.MeasurementsPrimary outcome measure was knowledge of one's dementia status, as reported in the survey. Patient characteristics included race/ethnicity, age, sex, survey year, cognition, function, comorbidity, and whether living in a nursing home.ResultsAmong subjects identified as having dementia by the prediction model, 43.5% to 50.2%, depending on the survey year, reported that they were informed of the dementia status by their physician. This proportion was lower among Hispanics (25.9%-42.2%) and non-Hispanic blacks (31.4%-50.5%) than among non-Hispanic whites (47.7%-52.9%). Our fully adjusted regression model indicated lower dementia awareness among non-Hispanic blacks (odds ratio [OR] = 0.74; 95% confidence interval [CI] = 0.58-0.94) and Hispanics (OR = 0.60; 95% CI = 0.43-0.85), compared to non-Hispanic whites. Having more instrumental activity of daily living limitations (OR = 1.65; 95% CI = 1.56-1.75) and living in a nursing home (OR = 2.78; 95% CI = 2.32-3.32) were associated with increased odds of subjects reporting being told about dementia by a physician.ConclusionLess than half of individuals with dementia reported being told by a physician about the condition. A higher proportion of non-Hispanic blacks and Hispanics with dementia may be unaware of their condition, despite higher dementia prevalence in these groups, compared to non-Hispanic whites. Dementia outreach programs should target diverse communities with disproportionately high disease prevalence and low awareness. J Am Geriatr Soc 68:1763-1770, 2020.
