RESUMO
BACKGROUND: Older adults with cognitive impairment exhibit different patterns of healthcare utilization compared to their cognitively healthy counterparts. Despite extensive research in high-income countries, similar studies in low- and middle-income countries are lacking. This study aims to investigate the population-level patterns in healthcare utilization among older adults with and without cognitive impairment in Mexico. METHODS: Data came from five waves (2001-2018) of the Mexican Health and Aging Study. We used self-reported measures for one or more over-night hospital stays, doctor visits, visits to homeopathic doctors, and dental visits in the past year; seeing a pharmacist in the past year; and being screened for cholesterol, diabetes, and hypertension in the past two years. Cognitive impairment was defined using a modified version of the Cross Cultural Cognitive Examination that assessed verbal memory, visuospatial and visual scanning. Total sample included 5,673 participants with cognitive impairment and 34,497 without cognitive impairment interviewed between 2001 and 2018. Generalized Estimating Equation models that adjusted for time-varying demographic and health characteristics and included an interaction term between time and cognitive status were used. RESULTS: For all participants, the risk for one or more overnight hospital stays, doctor visits, and dental visits in the past year, and being screened for diabetes, hypertension, and high cholesterol increased from 2001 to 2012 and leveled off or decreased in 2015 and 2018. Conversely, seeing a homeopathic doctor decreased. Cognitive impairment was associated with higher risk of hospitalization (RR = 1.13, 1.03-1.23) but lower risk of outpatient services (RR = 0.95, 0.93-0.97), cholesterol screening (RR = 0.93, 0.91-0.96), and diabetes screening (RR = 0.95, 0.92-0.97). No significant difference was observed in the use of pharmacists, homeopathic doctors, or folk healers based on cognitive status. Interaction effects indicated participants with cognitive impairment had lower risk for dental visits and hypertension screening but that these trajectories differed over time compared to participants without cognitive impairment. CONCLUSIONS: We identified distinct population-level trends in self-reported healthcare utilization and differences according to cognitive status, particularly for elective and screening services. These findings highlight the necessity for policy interventions to ensure older adults with cognitive impairment have their healthcare needs met.

BACKGROUND: The post-acute patient standardized functional items (Section GG) include non-response options such as refuse, not attempt and not applicable. We examined non-response patterns and compared four methods to address non-response functional data in Section GG at nation-wide inpatient rehabilitation facilities (IRF). METHODS: We characterized non-response patterns using 100% Medicare 2018 data. We applied four methods to generate imputed values for each non-response functional item of each patient: Monte Carlo Markov Chains multiple imputations (MCMC), Fully Conditional Specification multiple imputations (FCS), Pattern-mixture model (PMM) multiple imputations and the Centers for Medicare and Medicaid Services (CMS) approach. We compared changes of Spearman correlations and weighted kappa between Section GG and the site-specific functional items across impairments before and after applying four methods. RESULTS: One hundred fifty-nine thousand six hundred ninety-one Medicare fee-for-services beneficiaries admitted to IRFs with stroke, brain dysfunction, neurologic condition, orthopedic disorders, and debility. At discharge, 3.9% (self-care) and 61.6% (mobility) of IRF patients had at least one non-response answer in Section GG. Patients tended to have non-response data due to refused at discharge than at admission. Patients with non-response data tended to have worse function, especially in mobility; also improved less functionally compared to patients without non-response data. Overall, patients coded as 'refused' were more functionally independent in self-care and patients coded as 'not applicable' were more functionally independent in transfer and mobility, compared to other non-response answers. Four methods showed similar changes in correlations and agreements between Section GG and the site-specific functional items, but variations exist across impairments between multiple imputations and the CMS approach. CONCLUSIONS: The different reasons for non-response answers are correlated with varied functional status. The high proportion of patients with non-response data for mobility items raised a concern of biased IRF quality reporting. Our findings have potential implications for improving patient care, outcomes, quality reporting, and payment across post-acute settings.

OBJECTIVE: To estimate cognitively healthy life expectancy (CHLE), cognitive impairment life expectancy (CILE), and dementia life expectancy (DLE) in Mexican adults aged 60 and older stratified by educational attainment. MATERIALS AND METHODS: The data were obtained from Waves 1 (2001) to 5 (2018) of the Mexican Health and Aging Study. The life expectancy was estimated using a multistate life table analysis. RESULTS: CHLE at age 60 increased with higher educational attainment and ranged from 17.9 to 24.4 years in female participants, and 17.2 to 21.3 in male participants. The CILE and DLE decreased with greater educational attainment. The CILE ranged from 0.7 to 2.8 years in female participants and 0.7 to 2.6 in male participants. CONCLUSIONS: Older adults in Mexico with higher education live more years with good cognitive health and fewer years with cognitive impairment and dementia. Education has a stronger effect on the length of cognitively healthy life expectancies than on total life expectancies.

BACKGROUND: Breast cancer survivors have a unique risk for negative health outcomes. Engaging in routine physical activity (PA) can reduce these risks. However, PA levels are low among this population. Narrative visualization (NV) is a technique that uses drawings, photographs, and text to contextualize data, which may increase integrated regulation, or motivation related to personal values and identity. A PA intervention targeting breast cancer survivors using an NV strategy may improve PA behavior. The purpose of this study was to determine whether scrapbooking activities could successfully be used as an NV strategy for older (55+) breast cancer survivors. METHODS: Breast cancer survivors were given workbooks, wearable electronic activity monitors, instant cameras, and art supplies including a variety of stickers (e.g., emojis, affirmations). Participants were instructed to use these materials for 7 days. The workbook pages prompted participants to re-draw their daily activity graphs from the wearable's mobile app, then annotate them with text, photographs, stickers, etc. to reflect what the data meant to them. Hybrid thematic analysis was used to analyze the photographs, drawings, and written content to identify emergent themes. Content analysis was also used to investigate use of stickers and photographs. RESULTS: Of the 20 consented women (mean age 67 ± 5 years, 45% non-Hispanic white), 3 participants were lost to follow-up or unable to complete the procedures. The NV procedures were successfully utilized by the remaining 17 participants, who collectively used 945 stickers over 7 days, most of which were emojis. Emojis were both positively and negatively valanced. Participants took a mean of 9 photos over 7 days and completed workbook questions regarding current PA and PA goals. Themes within the photos included family, specific locations, everyday objects, religion, and friends. Themes within the written portions of the workbook included family, chores and obligations, health, personal reflection, hobbies, and shopping. CONCLUSIONS: The materials provided allowed breast cancer survivors to successfully use NV techniques to reflect on their PA data and behavior. These techniques show promise for promoting integrated regulation in activity monitoring interventions. TRIAL REGISTRATION: This study was funded by the National Cancer Institute ( R21CA218543 ) beginning July 1, 2018.

OBJECTIVE: To establish whether nonpharmacologic interventions, such as occupational and physical therapy, were associated with a shorter duration of prescription opioid use after hip or knee arthroplasty. DESIGN: This retrospective cohort study used data from a national 5% Medicare sample database between January 1, 2010 and December 31, 2015. SETTING: Home health or outpatient. PARTICIPANTS: Adults 66 years or older with an inpatient total hip (n=4272) or knee (n=9796) arthroplasty (N=14,068). INTERVENTIONS: We dichotomized patients according to whether they had received any nonpharmacologic pain intervention within 1 year after hospital discharge (eg, occupational or physical therapy evaluation). Using Cox proportional hazards, we treated exposure to nonpharmacologic interventions as time dependent to determine if skilled therapy was associated with duration of opioid use. MAIN OUTCOME MEASURES: Duration of prescription opioid use. RESULTS: Median time to begin nonpharmacologic interventions was 91 days (95% confidence interval [CI], 74-118d) for hip and 27 days (95% CI, 27-28d) for knee arthroplasty. Median time to discontinue prescription opioids was 16 days (hip: 95% CI, 15-16d) and 30 days (knee: 95% CI, 29-31d). Nonpharmacologic interventions delivered with home health increased the likelihood of discontinuing opioids after hip (hazard ratio [HR], 1.15; 95% CI, 1.01-1.30) and knee (HR, 1.10; 95% CI, 1.03-1.17) arthroplasty. A sensitivity analysis found these estimates to be robust and conservative. CONCLUSIONS: Occupational and physical therapy with home health was associated with a shorter duration of prescription opioid use after hip and knee arthroplasty. Occupational and physical therapy can address pain and sociobehavioral factors associated with postsurgical opioid use.

OBJECTIVE: To determine whether patients with a total or partial hip replacement admitted to a skilled nursing facility (SNF) after the improvement in function quality measure was added to Nursing Home Compare in July 2016 have greater physical recovery than patients admitted before July 2016. DESIGN: Pre (January 1, 2015-June 30, 2016) vs post (July 1, 2016-December 31, 2017) design. SETTING: Skilled nursing facilities (n=12,829). PARTICIPANTS: Medicare fee-for-service beneficiaries (N=106,832) discharged from acute hospitals to SNF after hip replacement between January 1, 2015 and December 31, 2017. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The 5- and 14-day minimum data set assessments were used to calculate total scores for the quality measure, self-care, mobility, and balance. We calculated the average adjusted change per 10 days and any improvement between the 5- and 14-day assessments. RESULTS: The average adjusted change per 10 days for the quality measure total score for patients admitted before July 2016 and after July 2016 was 1.00 points (standard error, 0010) and 1.06 points (standard error, 0.010), respectively (P<.01). This was a relative increase of 6.0%. Among patients admitted to a SNF before July 2016, 44.4% (standard error, 0.06) had any improvement in the quality measure total score compared with 45.5% (standard error, 0.23) of patients admitted after July 2016 (P<.01). This was a relative increase of 2.5%. The adjusted change per 10 days and percentage of patients who had any improvement in the total scores for self-care, mobility, and balance were all significantly higher after July 2016. CONCLUSIONS: Patients admitted to a SNF after a hip replacement after July 2016 had greater physical recovery than patients admitted before the improvement in function quality measure was added to Nursing Home Compare.

Stroke survivors may experience multiple residual symptoms post-stroke, including vision impairment (VI) and cognitive decline. Prior studies have shown that VI is associated with cognitive decline, but have not evaluated the contribution of VI to post-stroke cognitive changes. We used data from four waves (2010-2016) of the Health and Retirement Study to investigate the cognitive trajectories of stroke survivors with and without VI. Vision (excellent-very good[ref], good, fair-poor) and stroke diagnosis were self-reported. Cognition was defined using the Telephone Interview for Cognitive Status. Regression was used to model the association between vision and change in cognitive function, adjusting for confounders. The final sample included 1,439 stroke survivors and the average follow-up time was 4.1 years. Fair-poor overall (B = -1.30, p < 0.01), near (B = -1.53, p < 0.001), and distance (B = -1.27, p < 0.001) vision were associated with significantly lower baseline cognitive function. VI was not associated with the rate of cognitive decline. Future research should determine whether specific types of VI potentiate the risk of cognitive impairment and dementia in stroke survivors.

OBJECTIVE: To study the effects of disability, cognitive impairment, and neuropsychiatric disturbance among older Mexican Americans on depressive symptoms in their children caregivers. METHODS: This study utilizes data from Wave 7 (2010-2011) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE). The final sample included 200 adult children caregivers that provided direct personal care with activities of daily living (ADL) (e.g. bathing, toileting, dressing, etc.) to their older parents (average age = 87). We analyzed the influence of ADL disability, cognition (MMSE), and neuropsychiatric symptoms (NPI) of the care recipient on depressive symptoms of the adult child caregiver. A cross-sectional multivariable linear regression analysis was conducted to examine the effect of neuropsychiatric disturbance on caregiver depressive symptoms. RESULTS: Presence of care recipient NPI symptoms was associated with higher depressive symptoms for caregivers. Additional characteristics associated with caregiver depressive symptoms were not being married, and higher perceived social stress. ADL disability of the care recipient, cognitive functioning of the care recipient, or caregiver health status alone did not have a significant effect on depressive symptoms of the caregiver. CONCLUSIONS: In a Mexican American familistic culture, disability and cognitive impairment might be better tolerated by families but neuropsychiatric behavioral symptoms related to dementia may take an increased toll on family member caregivers. The need to provide respite services, mental health resources and community services for caregivers of care recipients with neuropsychiatric symptoms is of paramount importance to alleviate depressive symptoms and burden among caregivers.

OBJECTIVE: The purpose of this study was to determine the association between mobility, self-care, cognition, and caregiver support and 30-day potentially preventable readmissions (PPR) for individuals with dementia. DESIGN: This retrospective study derived data from 100% national Centers for Medicare and Medicaid Services data files from July 1, 2013, through June 1, 2015. PARTICIPANTS: Criteria from the Home Health Claims-Based Rehospitalization Measure and the Potentially Preventable 30-Day Post Discharge Readmission Measure for the Home Health Quality Reporting Program were used to identify a cohort of 118,171 Medicare beneficiaries. MAIN OUTCOME MEASURE: The 30-day PPR rates with associated 95% CIs were calculated for each patient characteristic. Multilevel logistic regression was used to study the relationship between mobility, self-care, caregiver support, and cognition domains and 30-day PPR during home health, adjusting for patient demographics and clinical characteristics. RESULTS: The overall rate of 30-day PPR was 7.6%. In the fully adjusted models, patients who were most dependent in mobility (odds ratio [OR], 1.59; 95% CI, 1.47-1.71) and self-care (OR, 1.73; 95% CI, 1.61-1.87) had higher odds for 30-day PPR. Patients with unmet caregiving needs had 1.11 (95% CI, 1.05-1.17) higher odds for 30-day PPR than patients whose caregiving needs were met. Patients with cognitive impairment had 1.23 (95% CI, 1.16-1.30) higher odds of readmission than those with minimal to no cognitive impairment. CONCLUSIONS: Decreased independence in mobility and self-care tasks, unmet caregiver needs, and impaired cognitive processing at admission to home health are associated with risk of 30-day PPR during home health for individuals with dementia. Our findings indicate that deficits in mobility and self-care tasks have the greatest effect on the risk for PPR.

Objective: To evaluate associations between depression and individual cognitive domains and how changes in depressive symptoms relate to cognition three years later in the context of Mexico, a developing country experiencing rapid aging.Method: Data comes from the 2012 and 2015 waves of the Mexican Health and Aging Study (n = 12,898, age 50+). Depression is ascertained using a modified Center for Epidemiologic Studies - Depression Scale. Cognition is assessed using verbal learning, verbal memory, visual scanning, verbal fluency, visuospatial ability, visual memory, and orientation tasks. Depressive symptoms and cognitive functioning were both measured in 2012 and 2015. Scores across cognitive domains are modeled using ordinary least squares regression, adjusting for demographic, health, and economic covariates.Results: When depression and cognition were measured concurrently in 2015, depression exhibited associations with all cognitive domains. When considering a respondent's history of depression, individuals who had elevated depressive symptoms in 2012 and recovered by 2015 continued to exhibit poorer cognitive function in 2015 in verbal learning, verbal memory, visual scanning, and verbal fluency tasks compared to individuals who were neither depressed in 2012 nor 2015.Conclusions: Depression was associated with cognition across cognitive domains among older Mexican adults. Despite improvements in depressive symptomatology, formerly depressed respondents continued to perform worse than their counterparts without a history of depression on several cognitive tasks. In addition to current mental health status, researchers should consider an individual's history of depression when assessing the cognitive functioning of older adults.

Research suggests that the prevalence and incidence of cognitive impairment among older adults is decreasing. This analysis used data from 9 waves (1993-2016) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly to assess cognitive status and cognitive decline for 2 cohorts of Mexican-Americans aged ≥75 years in 1993-1994 versus 2004-2005. Logistic regression, joint longitudinal survival models, and illness-death models for interval-censored data were used to examine cohort differences in the odds of prevalent cognitive impairment, trajectories of cognitive decline, and the risk of 10-year incident cognitive impairment, respectively. Results indicated that compared with the 1993-1994 cohort, the 2004-2005 cohort had higher odds for prevalent cognitive impairment (odds ratio = 2.51, 95% confidence interval (CI): 1.92, 3.29), particularly among participants with <4 years of education (odds ratio = 2.99, 95% CI: 2.14, 4.18). Conversely, the 2004-2005 cohort exhibited significantly slower rates of cognitive decline (ßË = 0.50, 95% CI: 0.39, 0.62) and had a significantly lower risk of incident cognitive impairment (hazard ratio = 0.75, 95% CI: 0.62, 0.91) compared with the 1993-1994 cohort. This analysis provides mixed results for cohort trends in the cognitive health of older Mexican-Americans. Continued research is needed to identify risk factors that contribute to these population-level trends.

BACKGROUND: Beginning in 2019, home health agencies' rates of potentially preventable hospital readmissions over the 30 days following discharge will be publicly reported. OBJECTIVES: Our primary objective was to determine the association between patients' functional status at discharge from home health care and 30-day potentially preventable readmissions. A secondary objective was to identify the most common conditions resulting in potentially preventable readmissions. DESIGN: This was a retrospective cohort study. PARTICIPANTS: A total of 1,510,297 Medicare fee-for-service beneficiaries discharged from home health care in 2013-2015. Average age was 75.9 (SD, 10.9) years, 60.0% were female, and 84.2% non-Hispanic white. MEASUREMENTS: Thirty-day potentially preventable readmissions following home health discharge. Functional status measures included mobility, self-care, and impaired cognition. RESULTS: The overall rate of 30-day potentially preventable readmissions was 2.6% (N=39,452), which accounted for 40% of all 30-day readmissions. After adjusting for sociodemographic and clinical characteristics, the odds ratios for the most dependent score quartile versus the most independent was 1.58 [95% confidence interval (CI), 1.53-1.63] for mobility and 1.65 (95% CI, 1.59-1.69) for self-care. The odds ratios for impaired versus intact cognition was 1.21 (95% CI, 1.18-1.24). The 5 most common conditions resulting in a potentially preventable readmission were congestive heart failure (23.6%), septicemia (16.7%), bacterial pneumonia (9.8%), chronic obstructive pulmonary disease (9.4%), and renal failure (7.5%). CONCLUSIONS: Functional limitations at discharge from home health are associated with increased risk for potentially preventable readmissions. Future research is needed to determine whether improving functional independence decreases the risk for potentially preventable readmissions following home health care.

BACKGROUND: Few studies have investigated the healthcare utilization of Mexican-American Medicare beneficiaries. We used survey data that has been linked with Medicare claims records to describe the healthcare utilization of Mexican-American Medicare beneficiaries, determine common reasons for hospitalizations, and identify characteristics associated with healthcare utilization. METHODS: Data came from wave five (2004/05) of the Hispanic Established Populations for the Epidemiological Study of the Elderly. The final sample included 1187 participants aged ≥75 who were followed for two-years (eight-quarters). Generalized estimating equations were used to estimate the probability of ≥1 hospitalization, emergency room (ER) admissions, and outpatient visits. RESULTS: The percentage of beneficiaries who had ≥1 hospitalizations, ER admissions, and outpatient visits for each quarter ranged from 10.12-12.59%, 14.15-19.03%, and 76.61-80.68%, respectively. Twenty-three percent of hospital discharges were for circulatory conditions and 17% were for respiratory conditions. Hospitalizations for heart failure and simple pneumonia were most common. Older age was associated with significantly higher odds for ER admissions (OR = 1.49, 95% CI = 1.21-1.84) but lower odds for outpatient visits (OR = 0.74, 95% CI = 0.57-0.96). Spanish language and female gender were associated with significantly higher odds for hospitalizations (OR = 1.53, 95% CI = 1.14-2.06) and outpatient visits (OR = 1.82, 95% CI = 1.43-2.33), respectively. Having a middle-school or higher level of education was associated with significantly lower odds for ER admissions (OR = 0.71, 95% CI = 0.56-0.91). Participants who were deceased within two-years had significantly higher odds for hospitalizations (OR = 6.15, 95% CI = 4.79-7.89) and ER admissions (OR = 3.63, 95% CI = 2.88-4.57) than participants who survived at least three-years. CONCLUSION: We observed high healthcare utilization among Mexican-American Medicare beneficiaries. Forty percent of all hospitalizations were for circulatory and respiratory conditions with hospitalizations for heart failure and pneumonia being the most common. Older age, gender, education, language, and mortality were all associated with healthcare utilization. Continued research is needed to identify patterns and clusters of social determinants and health characteristics associated with healthcare utilization and outcomes in older Mexican-Americans.

Objectives: Impaired cognition and pre-frailty are associated with poor health outcomes. However, research has not examined the combined impact of cognitive impairment and pre-frailty on future frailty and mortality among older Mexican Americans. Methods: Data for this analysis came from the 2006-2007 and 2010-2011 waves of the Hispanic EPESE. The final sample included 639 Mexican Americans aged ≥77 years who were non-frail or pre-frail in 2006-2007. Frailty measure included weight loss, exhaustion, weakness, and slow walking speed. Participants were classified as non-frail (0 criteria) and pre-frail (1 criterion) at baseline. Cognitive impairment was defined as <21 points on the MMSE. At baseline, participants were grouped as: cognitively intact non-frail, cognitively intact pre-frail, cognitively impaired non-frail, and cognitively impaired pre-frail. Logistic and hazard regression models were used to evaluate the odds of being frail in 2010-2011 and risk for 10-year mortality. Results: Cognitively impaired pre-frail participants were more likely to become frail (OR = 4.82, 95% CI = 2.02-11.42) and deceased (HR = 1.99, 95% CI = 1.42-2.78). Cognitively impaired non-frail participants had significantly higher risk for mortality (HR = 1.55, 95% CI = 1.12-2.19) but not frailty (OR = 1.29, 95% CI = 0.50-3.11). Being cognitively intact and pre-frail at baseline was not significantly associated with being frail at follow-up (OR = 1.62, 95% CI = 0.83-3.19) or mortality (HR = 1.29, 95% CI = 0.97-1.71). Conclusions: Comorbid cognitive impairment and pre-frailty is associated with future frailty and mortality in older Mexican Americans. Screening for cognitive impairment may be effective for identifying pre-frail Mexican Americans who are at the highest risk of frailty and mortality.

OBJECTIVE: The increased risk for poor physical and mental health outcomes for older parents in Mexico who have an adult child living in the United States may contribute to an increased risk for cognitive impairment in this population. The objective of this study was to examine if older adults in Mexico who have one or more adult children living in the United States are more or less likely to develop cognitive impairment over an 11-year period compared to older adults who do not have any adult children living in the United States. DESIGN: Data for this study came from Wave I (2001) and Wave III (2012) of the Mexican Health and Aging Study. The final sample included 2609 participants aged 60 and over who were not cognitively impaired in 2001 and had one or more adult children (age ≥15). Participants were matched using a propensity score that was estimated with a multivariable logistic regression model that included sociodemographic characteristics and migration history of the older parents. RESULTS: Having one or more adult children living in the United States is associated with lower socioeconomic status and higher number of depressive symptoms, but greater social engagement for older parents living in Mexico. No significant differences in the odds for developing cognitive impairment according to having one or more adult children living in the United States were detected. CONCLUSION: In summary, having one or more adult children living in the United States was associated with characteristics that may increase and decrease the risk for cognitive impairment. This may contribute to the non-significant relationship between migration status of adult children and likelihood for cognitive impairment for older parents living in Mexico.

INTRODUCTION: Older Mexican Americans are living longer with multiple chronic conditions (MCCs). This has placed greater demands on caregivers to assist with basic activities of daily living (ADL) or instrumental activities of daily living (IADL). To understand the needs of older Mexican-American care recipients, we examined the impact of MCC on ADL and IADL limitations. METHODS: We analyzed data from 485 Mexican American care-receiving/caregiving dyads. Selected MCCs in the analysis were diabetes, hypertension, stroke, heart disease, arthritis, emphysema/chronic obstructive pulmonary disease, cognitive impairment, depression, and cancer. Care recipients were dichotomized as having 3 or more conditions or as having 2 or fewer conditions. Three comorbidity clusters were established on the basis of the most prevalent health conditions among participants with comorbid arthritis and hypertension. These clusters included arthritis and hypertension plus: diabetes (cluster 1), cognitive impairment (cluster 2), and heart disease (cluster 3). RESULTS: Care recipients with 3 or more chronic conditions (n = 314) had higher odds of having mobility limitations (OR = 1.98; 95% CI, 1.34-2.94), self-care limitations (OR = 2.53; 95% CI, 1.70-3.81), >3 ADL limitations (OR = 2.00; 95% CI, 1.28-3.17), and >3 IADL limitations (OR = 1.88; 95% CI, 1.26-2.81). All clusters had increased odds of ADL and severe ADL limitations. Of care recipients in cluster 2, those with arthritis, hypertension, and cognitive impairment had significantly higher odds of mobility limitations (OR = 2.33; 95% CI, 1.05-5.24) than those with just arthritis and hypertension. CONCLUSION: MCCs were associated with more ADL and IADL limitations among care recipients, especially for those with hypertension and arthritis plus diabetes, cognitive impairment, or heart disease. These findings can assist in developing programs to meet the needs of older Mexican-American care recipients.

BACKGROUND: Older Black and Hispanic adults are more likely to be cognitively impaired than older White adults. Disadvantages in educational achievement for minority and immigrant populations may contribute to disparities in cognitive impairment. OBJECTIVE: Examine the role of education in racial/ethnic and nativity differences in cognitive impairment/no dementia (CIND) and dementia among older US adults. METHODS: Data comes from the 2012 Health and Retirement Study. A total of 19,099 participants aged ≥50 were included in the analysis. Participants were categorized as having normal cognition, CIND, or dementia based on the Telephone Interview for Cognitive Status (TICS) or questions from a proxy interview. We document age and educational differences in cognitive status among White, Black, US-born Hispanic, and foreign-born Hispanic adults by sex. Logistic regression is used to quantify the association between race/ethnicity/nativity, education, and cognitive status by sex. RESULTS: Among women, foreign-born Hispanics have higher odds of CIND and dementia than Whites. For men, Blacks have higher odds for CIND and dementia compared to Whites. The higher odds for CIND and dementia across race/ethnic and nativity groups was reduced after controlling for years of education but remained statistically significant for older Black and US-born Hispanic adults. Controlling for education reduces the odds for CIND (women and men) and dementia (men) among foreign-born Hispanics to nonsignificance. CONTRIBUTION: These results highlight the importance of education in CIND and dementia, particularly among foreign-born Hispanics. Addressing inequalities in education can contribute to reducing racial/ethnic/nativity disparities in CIND and dementia for older adults.
RESUMO
OBJECTIVE: To identify distinct trajectories for global cognition, memory, and non-memory domains among Mexican American adults 75 years of age and older. METHODS: The final sample included 1336 participants of the Hispanic Established Population for the Epidemiologic Study of the Elderly observed during four Waves from 2004-2005 to 2012-2013. Latent class growth curve models were used to identify distinct trajectories for global cognition, memory, and non-memory. RESULTS: Three trajectory classes were identified for global cognition, memory, and non-memory domains. Nearly 31% of the final sample maintained high global cognition (persistent high), 52.6% experienced slight decline (decline but high), and 15% experienced severe decline in global cognition (decline to low). Over 95% of participants classified in the decline to low trajectory for global cognition were also classified as decline to low for memory and non-memory. This high level of consistency for memory and non-memory domains was observed for the decline but high (97.0%) and persistent high (93.7%) trajectory classes. CONCLUSIONS: These results indicate that the majority of Mexican American older adults will experience varying degrees of cognitive decline. However, a substantial proportion of older Mexican Americans are able to maintain high cognitive functioning into advanced age despite the high prevalence of risk factors for cognitive decline in this population.

OBJECTIVE: Examine differences in cognition between Hispanic, non-Hispanic black (NHB), and non-Hispanic white (NHW) older adults in the United States. DATA/METHODS: The final sample includes 18 982 participants aged 51 or older who received a modified version of the Telephone Interview for Cognitive Status during the 2010 Health and Retirement Study follow-up. Ordinary least squares will be used to examine differences in overall cognition according to race/ethnicity. RESULTS: Hispanics and NHB had lower cognition than NHW for all age groups (51-59, 60-69, 70-79, 80+). Hispanics had higher cognition than NHB for all age groups but these differences were all within one point. The lower cognition among NHB compared to NHW remained significant after controlling for age, gender, and education, whereas the differences in cognition between Hispanics and NHW were no longer significant after controlling for these covariates. Cognitive scores increased with greater educational attainment for all race/ethnic groups, but Hispanics exhibited the least benefit. DISCUSSION: Our results highlight the role of education in race/ethnic differences in cognitive function during old age. Education seems beneficial for cognition in old age for all race/ethnic groups, but Hispanics appear to receive a lower benefit compared to other race/ethnic groups. Further research is needed on the racial and ethnic differences in the pathways of the benefits of educational attainment for late-life cognitive function. Copyright © 2016 John Wiley & Sons, Ltd.

OBJECTIVE: Metabolic and vascular conditions have been independently associated with dementia and cognitive decline among older adults, but research on the combined effects that these conditions have on cognitive decline, especially among older Mexican Americans, is lacking. The purpose of this study was to examine the relationship between metabolic and vascular conditions and cognitive decline among older Mexican Americans. METHODS: The final sample included 2767 participants of the Hispanic Established Populations for the Epidemiologic Study of the Elderly. Linear mixed-effects regression was used to model cognitive decline across six examinations (1993-2007) according to the number (zero, one, two, and three to four) of metabolic and vascular conditions (hypertension, diabetes, stroke, and heart attack). RESULTS: Of the 2767 participants included in the final sample, 777 had zero conditions, 1314 had one condition, 553 had two conditions, and 123 had three to four conditions. Participants with two or three to four conditions had significantly greater cognitive decline compared with participants with zero or one condition. Stroke had the largest effect size on cognitive decline based on the proportion of variance that stroke accounted for in the linear mixed-effects model. CONCLUSION: Mexican American older adults with multiple metabolic and vascular conditions exhibit greater cognitive decline than those with zero or one condition. Public health interventions designed to reduce the prevalence of chronic metabolic and vascular conditions, in particular stroke, may limit the severity of cognitive decline among older Mexican Americans.
