Cardiometabolic risk factors, including hypertension, dyslipidemia, central obesity, insulin resistance and diabetes are linked to cognitive impairment. The Hispanic population appears to be differentially affected by both cardiometabolic risk factors and cognitive impairment. We sought to determine whether ethnic differences in cognitive impairment in long-resident southwestern US elders was explained by the presence of cardiometabolic risk factors, and to explore patterns of cognitive decline over time. We performed a secondary analysis of data collected on 378 Hispanic and 409 non-Hispanic white adult participants in a longitudinal study of community dwelling elderly in southern Colorado. Measures of cardiometabolic risk included waist circumference, blood pressure, diagnosis of diabetes, and random blood glucose. Cognitive measures included the Mini-Mental State Exam (MMSE) and the behavioral dyscontrol scale (a measure of executive cognitive function), at baseline and after an average of 22 months. Subjects were also administered the Center for Epidemiologic Studies Depression Scale, and the Coronary Artery Risk Development in Young Adults 1-Year Activity Recall. At baseline, Hispanic elders had a greater number of cardiometabolic risk factors and lower MMSE and behavioral dyscontrol scale scores than non-Hispanic whites. Hispanic ethnicity was associated with a greater likelihood of decline in general cognitive function, but not executive cognitive function, after adjusting for age and education. This differential decline was not explained by either individual or total number of baseline cardiometabolic risk factors, depression, or physical activity. A borderline increased risk of decline in general cognitive function was seen in sedentary individuals (P = 0.05).

Purpose: Most individuals with Alzheimer's are cared for in their homes by unpaid family members. Research on caregiving focuses disproportionally on costs of care, service utilization, and negative psychosocial outcomes. Few narrative accounts of Alzheimer's exist; those that do suffer similar pejorative framings and narrow foci. No studies that we are aware of examine the health beliefs of diagnosed individuals and support persons, or their attitudes about brain health. This research reports perceptions of 'aging well' held by those most intimately acquainted with Alzheimer's. Design and Methods: Diagnosed individuals and their support persons (N = 85) were enrolled into 14 focus groups. Grounded theory methods were used to collect, code, and analyze textual interview data into overarching themes. Results: Respondents found physical and mental health, social activity, independence, and happiness integral to aging well. An acceptance of various limitations was also deemed crucial. Support persons placed more emphasis on lifestyle factors and memory loss as potential obstacles. Diagnosed respondents defined memory loss in less medicalized terms, whereas support persons labeled it Alzheimer's and negatively characterized those affected. Both groups warned against discussing 'prevention' of dementia: Diagnosed individuals noted the implication of 'aging poorly' and support persons cautioned against blaming diagnosed individuals. Implications: These findings can be used to encourage positive health beliefs and behaviors tailored to the needs of diagnosed seniors and their families, to help practitioners and researchers identify and become sensitive to differences between and among older adults, and to further advance the utility of narrative accounts for informing health interventions and education efforts.

Purpose: Description of study participants and documentation of the desired diversity in the Prevention Research Centers Healthy Aging Research Network's Workgroup on Promoting Cognitive Health large multisite study designed to examine attitudes about brain health, behaviors associated with its maintenance, and information-receiving preferences among a diverse group of older Americans, to provide a foundation for developing health promotion interventions. Design and Methods: Four hundred fifty older adults in 55 focus groups at 9 sites completed a common participant survey. Using descriptive statistics, the analysis compares participant characteristics (age, sex, and race/ethnicity; rural-urban location; income and education; social activity; physical activity, nutrition, and body mass index; and self-reported measures of cognitive function) across sites and with national data. Results: Comparisons across sites document the rich diversity of the sample. Implications: The substantial representation of a variety of demographic groups suggests that the qualitative data obtained in the focus group research provide a useful basis for developing well-targeted communication interventions for promoting brain health in diverse populations.

Purpose: Evidence suggests that healthy lifestyles may help maintain cognitive health. The Prevention Research Centers Healthy Aging Research Network, 9 universities collaborating with their communities and the Centers for Disease Control and Prevention, is conducting a multiyear research project, begun in 2005, to understand how to translate this knowledge into public health interventions. Design and Methods: This article provides an overview of the study purpose, design, methods, and processes. We examined the literature on promoting cognitive health, convened a meeting of experts in cognitive health and public health interventions, identified research questions, developed a common focus group protocol and survey, established quality control and quality assurance processes, conducted focus groups, and analyzed the resulting data. Results: We conducted 55 focus groups with 450 participants in 2005-2007, and an additional 20 focus groups and in-depth interviews in 2007-2008. Focus groups were in English, Spanish, Mandarin, Cantonese, and Vietnamese, with African Americans, American Indians, Asian Americans, Hispanics, non-Hispanic Whites, physicians and other health practitioners, rural and urban residents, individuals caring for family or friends with cognitive impairment, and cognitively impaired individuals. Implications: The data provide a wealth of opportunities for designing public health interventions to promote cognitive health in diverse populations.

Background. Pain often accompanies chronic disease in older adults and may exacerbate physical limitations, which the Disablement Model suggests may increase disability and decrease independence. This study tests the hypothesis that chronic pain and change in levels of pain over time have associations with worsening physical performance independent of disease conditions. Methods. We studied the effects of initial and changing levels of pain on observed physical performance over approximately 22 months in 925 community-dwelling Hispanic and non-Hispanic white participants in the San Luis Valley Health and Aging Study. Logistic regression models controlled for demographic variables, baseline performance, and comorbidities. Results. We found that chronic pain has an independent association with worsening physical performance, regardless of ethnicity. The intensity of the pain appears to have no independent effect. Although the presence of multiple comorbidities (or vascular disease or diabetes singly) also increases the risk of a worsened physical performance outcome, an independent effect of chronic pain remains after adjusting for these disease conditions. Furthermore, ongoing chronic pain increases the risk of worsening performance; obversely, recovery from chronic pain has a significant and substantial protective effect. Conclusions. Pain in and of itself appears to increase physical impairment. These results strongly suggest that controlling chronic pain may interrupt the negative disease--impairment--disability trajectory by significantly reducing impaired physical performance, no matter the disease conditions that may underlie the pain.

Purpose: Although increased participation in physical activity by older adults is a major public health goal, little is known about the supply and use of physical activity programs in the United States. Design and Methods: Seven academic centers in diverse geographic areas surveyed physical activity programs for older adults. Five sites conducted surveys by mail with telephone follow-up, and two administered surveys primarily by telephone. Reported program attendance rates were compared with local census data to assess unmet needs. Results: Of the 2,110 targeted facilities, 77% responded. Aerobic programs were offered by 73%, flexibility by 47%, and strength training by 26%. Commercial gyms or YMCAs, senior centers, park or recreation centers, and senior-housing facilities offered 90% of available programs. The 2000 Census enumerated 1,123,401 total older adults across the seven sites. Facilities reported 69,634 individuals as current weekly program participants, equaling 6% of the sites' total older-adult population. This percentage varied from 3% in Pittsburgh to 28% in Colorado. Implications: Based on conservative estimates of demand, the number of physical activity programs would have to increase substantially (by 78%) to meet the needs of older adults. The data also indicate the need to develop more strength-training programs and to engage a higher percentage of older adults in these programs. There is a clear need to stimulate demand for programs through health promotion. Key Words: Exercise, Needs and demand, Providers, Facilities

Purpose: This study identified modifiable risks associated with incident functional dependence, compared their effects, and estimated the percent risk attributable to each factor, by ethnicity. Design and Methods: The prospective study cohort comprised 751 rural Hispanic and non-Hispanic White elders from southern Colorado who reported no dependence in basic and instrumental activities of daily living (ADLs and IADLs) at baseline. Logistic regression modeled the effects of physical inactivity, nutritional risk, smoking, and falls on incident disability 22 months later, with and without adjustment for baseline ADL and IADL difficulty. Population attributable risk percentages assessed these modifiable risks by ethnicity. Results: Each risk factor multiplied the likelihood of incident dependence by 1.4 or more, adjusted for covariates. Attributable risk percentages ranged from 8% to 32% depending on risk factor, ethnicity, and baseline ADL and IADL difficulty status. Attributable risk was generally greater among Hispanic elders, the result of higher prevalence of most of the risk factors. Implications: Interventions targeted at inadequate nutrition, inactivity, smoking, and preventable falls offer opportunities to reduce incident functional disability, especially among Hispanic elders.

This cross-sectional study examines utilization of health care resources, including nursing homes, among 1,433 rural Hispanic and non-Hispanic White participants in the San Luis Valley Health and Aging Study. Results show substantially greater non-Hispanic White residence in nursing homes, greater Hispanic use of professional home nursing services, but little ethnic difference in outpatient care or hospitalization. Analyses based on the behavior model of utilization find health care use strongly associated with need factors. In particular, outpatient care correlated with disease and instrumental daily living activity dependence, home nursing care with basic daily living activity dependence, and nursing home use with daily living activity dependence and cognitive impairment. Predisposing characteristics (age, marital status, education) and enabling supports and barriers (insurance, availability of no- or low-cost care, transportation difficulties) also influenced utilization. The differential ethnic pattern of nursing home use persisted after controlling for these important characteristics.

Many previous studies have assessed the aging process by measuring clinical and functional variables. To supplement that quantitative understanding, we asked older people what constitutes their health and contributes to it. Using grounded theory-type methods, we analyzed semi-structured interviews with 22 study subjects, who were randomly selected from among those whose reported perceived health differed from that predicted by a regression model constructed from data from a randomized trial of a primary care intervention. We focused on disparate cases to identify factors that best discriminate between more and less healthy aging. Interview questions targeted perceptions of health; well-being; valued abilities, activities, and relationships; social support; control; sense of coherence; and personal outlook. A model of healthy aging emerged. To these older people health meant going and doing something meaninqful, which required four components: something worthwhile to do, balance between abilities and challenges, appropriate external resources, and personal attitudinal characteristics (e.g., positive attitude vs. 'poor me'). By reframing healthy aging in older people's own terms, this model encourages interdisciplinary support of their desired goals and outcomes rather than only medical approaches to deficits and challenges.
