Background: The association of hypertension (HTN) severity and control with the risk of incident atrial fibrillation (AF) is unclear. Hypothesis: Increased HTN severity and poorer blood pressure control would be associated with an increased risk of incident AF. Methods: This analysis included 9485 participants (mean age 63 ± 8 years; 56% women; 35% Black). Participants were stratified into six mutually exclusive groups at baseline—normotension (n = 1629), prehypertension (n = 704), controlled HTN (n = 2224), uncontrolled HTN (n = 4123), controlled apparent treatment‐resistant hypertension (aTRH) (n = 88), and uncontrolled aTRH (n = 717). Incident AF was ascertained at the follow‐up visit, defined by either electrocardiogram or self‐reported medical history of a physician diagnosis. Multivariable logistic regression analyses adjusted for demographic and clinical variables. Results: Over an average of 9.3 years later, 868 incident AF cases were detected. Compared to those with normotension, incident AF risk was highest for those with aTRH (controlled aTRH: odds ratio (OR) 2.95; 95% confidence interval (CI) 1.60, 5.43, & uncontrolled aTRH: OR 2.47; 95% CI 1.76, 3.48). The increase in AF risk was smaller for those on no more than three antihypertensive agents regardless of their blood pressure control (controlled OR 1.72; 95% CI 1.30, 2.29 and uncontrolled OR 1.56; 95% CI 1.14, 2.13). Conclusions: The risk of developing AF is increased in all individuals with HTN. Risk is highest in those aTRH regardless of blood pressure control. A more aggressive approach that focuses on lifestyle and pharmacologic measures to either prevent HTN or better control HTN during earlier stages may be particularly beneficial in reducing related AF risk.

Background: Retirement represents a crucial transitional period for many adults with possible consequences for cognitive aging. We examined trajectories of cognitive change before and after retirement in Black and White adults. Methods: Longitudinal examination of up to 10 years (mean = 7.1 ± 2.2 years) using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study–a national, longitudinal study of Black and White adults ≥45 years of age. Data were from 2226 members of the REGARDS study who retired around the time when an occupational ancillary survey was administered. Cognitive function was an average of z‐scores for tests of verbal fluency, memory, and global function. Results: Cognitive functioning was stable before retirement (Estimate = 0.05, p = 0.322), followed by a significant decline after retirement (Estimate = −0.15, p < 0.001). The decline was particularly pronounced in White (Estimate = −0.19, p < 0.001) compared with Black (Estimate = −0.07, p = 0.077) participants, twice as large in men (Estimate = −0.20, p < 0.001) compared with women (Estimate = −0.11, p < 0.001), highest among White men (Estimate = −0.22, p < 0.001) and lowest in Black women (Estimate = −0.04, p = 0.457). Greater post‐retirement cognitive decline was also observed among participants who attended college (Estimate = −0.14, p = 0.016). While greater work complexity (Estimate = 0.92, p < 0.05) and higher income (Estimate = 1.03, p < 0.05) were related to better cognitive function at retirement, neither was significantly related to cognitive change after retirement. Conclusion: Cognitive functioning may decline at an accelerated rate immediately post‐retirement, more so in White adults and men than Black adults and women. Lifelong structural inequalities including occupational segregation and other social determinants of cognitive health may obscure the role of retirement in cognitive aging. [ABSTRACT FROM AUTHOR]

Background: The work environment can contribute to the risk of cardiovascular diseases (CVD) including stroke. Our objective was to identify occupations with elevated risk of stroke within the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. Methods: We analyzed incident stroke outcomes (ischemic and hemorrhagic strokes) from 2003 to 2020 and employment characteristics of 13,659 adults aged ≥45 years enrolled in a national population‐based cohort study. Using a modified Poisson regression approach, we estimated the relative risks (RRs) and the associated 95% confidence intervals (CI) of stroke in relation to years of employment within each occupation coded using the US Census two‐digit Standard Occupation Code. Models were adjusted for Framingham Stroke Risk Score, region, race, age, and body mass index. We conducted stratified analysis by sex, employment time period (pre‐1975 vs. post‐1975), and region. Results: Workers in the following occupations had a greater risk of stroke with longer duration of employment (per decade): protective service (RR: 2.35, 95% CI: 1.11, 4.97), food preparation and service (RR: 1.51, 95% CI: 1.05, 2.19), and transportation and material moving (RR: 1.30, 95% CI: 1.00, 1.69). The stroke risk in these occupations was disproportionately elevated in men, and differed by region and employment time period. Conclusions: Longer employment in protective service, food preparation and serving, and transportation and materials moving occupations may increase the risk of stroke. Surveillance may uncover specific work‐related risk factors in these occupations, leading to interventions to reduce the burden of stroke among US workers. [ABSTRACT FROM AUTHOR]

Purpose: We previously described the magnitude of rural‐urban differences in the prevalence of stroke risk factors and stroke mortality. In this report, we sought to extend the understanding of rural‐urban differences in the prevalence of stroke risk factors by using an enhanced definition of rural‐urban status and assessing the impact of neighborhood socioeconomic status (nSES) on risk factor differences. Methods: This analysis included 28,242 participants without a history of stroke from the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort. Participants were categorized into the 6‐level ordinal National Center for Health Statistics Urban‐Rural Classification Scheme. The prevalence of stroke risk factors (hypertension, diabetes, smoking, atrial fibrillation, left ventricular hypertrophy, and heart disease) was assessed across the rural‐urban scale with adjustment for demographic characteristics and further adjustment for nSES score. Findings: Hypertension, diabetes, and heart disease were more prevalent in rural than urban regions. Higher odds were observed for these risk factors in the most rural compared to the most urban areas (odds ratios [95% CI]: 1.25 [1.11‐1.42] for hypertension, 1.15 [0.99‐1.33] for diabetes, and 1.19 [1.02‐1.39] for heart disease). Adjustment for nSES score partially attenuated the odds of hypertension and heart disease with rurality, completely attenuated the odds of diabetes, and unmasked an association of current smoking. Conclusions: Some of the higher stroke mortality in rural areas may be due to the higher burden of stroke risk factors in rural areas. Lower nSES contributed most notably to rural‐urban differences for diabetes and smoking. [ABSTRACT FROM AUTHOR]

Socioeconomic status (SES) is a well‐established determinant of health. Disparities in stress are thought to partially account for SES‐health disparities. We tested whether multiple indicators of SES show similar associations with psychological stress and whether race, sex, and geographic region moderate associations. Participants (n = 26,451) are from a well‐characterized national cohort of Black and White US adults aged 45 years or older. Psychological stress was measured using the 4‐item perceived stress scale. Income was assessed as annual household income and education as highest level of education completed. Occupation was assessed during a structured interview and subsequently coded hierarchically. For all sex‐race‐region groups, the largest SES‐stress associations were for income and the smallest were for occupation. Race moderated SES‐stress associations, such that income and education were more closely associated with stress in Black adults than White adults. Additionally, education was more strongly associated with stress in individuals living in the stroke belt region. Black Americans with lower income and education reported greater psychological stress and may be at higher risk for disease through stress‐related pathways. Thus, which SES indicator is examined and for whom may alter the magnitude of the association between SES and psychological stress. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The Mediterranean‐DASH Intervention for Neurodegenerative Delay (MIND) diet (high in nuts, seeds, vegetables, berries and low in meat, dairy, and butter) has been associated with reduced risk of dementia. However, no studies have examined the role of the MIND diet in a racially diverse population nor have there been studies that have examined the association of the MIND diet with dementia mortality. Method: We examined data from Black and White adults (age 45‐98) in the US‐based REGARDS cohort. Dietary and covariate data were collected at baseline (2002‐2007). MIND diet score was created as described by other cohort studies (Table footnote). The primary outcome was dementia‐related mortality through December 31, 2020 from the National Death Index using ICD‐10 codes F00‐F03, G30, G31.0‐G31.1, and R54. Cox proportional hazards regression was used to model MIND diet score (in tertiles and as a continuous variable) and time to dementia death. To ensure robust association across sub‐groups, we tested for interactions of MIND diet with sex, race, age, obesity, history of stroke, and baseline cognitive impairment and adjusted for competing risks. Result: A total of 18,277 participants (mean age 64.9) had dietary data available to calculate the MIND diet score. MIND diet score was higher among females compared with males, White compared with Black participants, and college graduates. There were no differences in accordance by age. After a median of 12 years, participants with the highest MIND diet scores had the lowest risk of dementia death HR = 0.78 {95% CI; (0.66, 0.94)} comparing the 3rd tertile with the 1st tertile and after adjustment for age, race, sex, income, education, total energy, and other medical conditions (Table). This association was attenuated slightly when a competing risk analysis was considered HR = 0.84 {95%CI; (0.70, 1.00)}. There were no significant interactions observed. Conclusion: The MIND diet score is associated with dementia death in a large bi‐racial cohort in the US. This association is robust across race, age, and sex groups. Dietary interventions using the MIND diet may further clarify whether this association is causal and whether MIND diet may be an important tool in reducing rates of dementia. [ABSTRACT FROM AUTHOR]

BACKGROUND/OBJECTIVES: Few studies have rigorously examined the magnitude of changes in well‐being after a transition into sustained and substantial caregiving, especially in population‐based studies, compared with matched noncaregiving controls. DESIGN: We identified individuals from a national epidemiological investigation who transitioned into caregiving over a 10‐ to 13‐year follow‐up and provided continuous in‐home care for at least 18 months and at least 5 hours per week. Individuals who did not become caregivers were individually matched with caregivers on age, sex, race, education, marital status, self‐rated health, and history of cardiovascular disease at baseline. Both groups were assessed at baseline and follow‐up. SETTING: REasons for Geographic And Racial Differences in Stroke study. PARTICIPANTS: A total of 251 incident caregivers and 251 matched controls. MEASUREMENTS: Perceived Stress Scale (PSS), 10‐Item Center for Epidemiological Studies‐Depression (CES‐D), and 12‐item Short‐Form Health Survey quality‐of‐life mental (MCS) and physical (PCS) component scores. RESULTS: Caregivers showed significantly greater worsening in PSS, CES‐D, and MCS, with standardized effect sizes ranging from 0.676 to 0.796 compared with changes in noncaregivers. A significant but smaller effect size was found for worsening PCS in caregivers (0.242). Taking on sustained caregiving was associated with almost a tripling of increased risk of transitioning to clinically significant depressive symptoms at follow‐up. Effects were not moderated by race, sex, or relationship to care recipient, but younger caregivers showed greater increases in CES‐D than older caregivers. CONCLUSION: Persons who began substantial, sustained family caregiving had marked worsening of psychological well‐being, and relatively smaller worsening of self‐reported physical health, compared with carefully matched noncaregivers. Previous estimates of effect sizes on caregiver well‐being have had serious limitations due to use of convenience sampling and cross‐sectional comparisons. Researchers, public policy makers, and clinicians should note these strong effects, and caregiver assessment and service provision for psychological well‐being deserve increased priority.

Objective: This study examined whether metabolic health status is associated with risk of cancer mortality and whether this varies by body mass index (BMI) category.Methods: A prospective study of 22,514 participants from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort was performed. Metabolically unhealthy status was defined as having three or more of the following: (1) elevated fasting glucose, (2) high triglycerides, (3) dyslipidemia, (4) hypertension, and (5) elevated waist circumference. Participants were categorized into normal weight (BMI 18.5-24.9 kg/m2 ), overweight (BMI 25.0-29.9 kg/m2 ), and obesity (BMI ≥ 30 kg/m2 ) groups. Cox proportional hazards regression was performed to estimate hazards ratios (HRs) and 95% confidence intervals (CIs) for cancer mortality during follow-up.Results: Among participants with normal weight, participants who were metabolically unhealthy had an increased risk of cancer mortality (HR: 1.65; 95% CI: 1.20-2.26) compared with metabolically healthy participants. The overall mortality risk for participants who were metabolically unhealthy and had normal weight was stronger for obesity-related cancers (HR: 2.40; 95% CI: 1.17-4.91). Compared with participants with normal weight, those who were metabolically healthy and overweight were at a reduced risk of any cancer mortality (adjusted HR: 0.79; 95% CI: 0.63-0.99).Conclusions: There was an increased risk of overall and obesity-related cancer mortality among metabolically unhealthy participants with normal weight.

Background/Objectives: Social support can prevent or delay long‐term nursing home placement (NHP). The purpose of our study was to understand how the availability of a caregiver can affect NHP after ischemic stroke and how this affects different subgroups differently. Design: Nested cohort study. Setting: Nationally based REasons for Geographic and Racial Differences in Stroke (REGARDS) study. Participants: Stroke survivors aged 65 to 100 (256 men, 304 women). Measurements: Data were from Medicare claims from January 2003 to December 2013 and REGARDS baseline interviews conducted from January 2003 to October 2007. Caregiver support was measured by asking, “If you had a serious illness or became disabled, do you have someone who would be able to provide care for you on an on‐going basis?” Diagnosis of ischemic stroke was derived from inpatient claims. NHP was determined using a validated claims algorithm for stays of 100 days and longer. Risk was estimated using Cox regression. Results: Within 5 years of stroke, 119 (21.3%) participants had been placed in a nursing home. Risk of NHP was greater in those lacking available caregivers (log‐rank
P = .006). After adjustment for covariates, lacking an available caregiver increased the risk of NHP after stroke within 1 year by 70% (hazard ratio (HR) = 1.70, 95% confidence interval (CI) = 0.97–2.99) and within 5 years by 68% (HR = 1.68, 95% CI = 1.10–2.58). The effect of caregiver availability on NHP within 5 years was limited to men (HR = 3.15, 95% CI = 1.49–6.67). Conclusion: In men aged 65 and older who have survived an ischemic stroke, the lack of an available caregiver is associated with triple the risk of NHP within 5 years.

Objectives To describe the incidence of cardiovascular risk factors, or race-related disparities in incidence, across the age spectrum in adults. Design Longitudinal cohort. Setting National sample. Participants Community-dwelling black and white adults recruited between 2003 and 2007. Measurements Incident hypertension, diabetes mellitus, dyslipidemia and atrial fibrillation over 10 years of follow-up in 10,801 adults, stratified according to age (45-54, 55-64, 65-74, ≥75). Results There was no evidence ( P ≥ .68) of an age-related difference in the incidence of hypertension for white men (average incidence 38%), black men (48%), or black women (54%), although for white women incidence increased with age (45-54, 27%; ≥75, 40%). Incidence of diabetes mellitus was lower at older ages for white men (45-54, 15%; ≥75, 8%), black men (45-54, 29%; ≥75, 13%), and white women (45-54, 11%; ≥75, 4%), although there was no evidence ( P = .11) of age-related changes for black women (average incidence 21%). For dyslipidemia, incidence for all race-sex groups was approximately 20% for aged 45 to 54 but approximately 30% for aged 54 to 64 and 65 to 74 and approximately 22% for aged 75 and older. Incidence of atrial fibrillation was low at age 45 to 54 (<5%) but for aged 75 and older was approximately 20% for whites and 11% for blacks. The incidence of hypertension, diabetes mellitus, and dyslipidemia was higher in blacks across the age spectrum but lower for atrial fibrillation. Conclusion Incidence of risk factors remains high in older adults. Blacks have a higher incidence of hypertension, diabetes mellitus, and dyslipidemia after age 45, underscoring the ongoing importance of prevention of all three conditions in mid- to later life.

Objectives To examine the relationship between objectively measured physical activity (PA) and cognitive function in white and black older adults. Design Cross-sectional. Setting REasons for Geographic and Racial Differences in Stroke (REGARDS) study. Participants Older adults who provided valid data from accelerometer and cognitive function tests (N = 7,098). Measurements Accelerometers provided estimates of PA variables for 4 to 7 consecutive days. PA cut-points of 50 counts per minute (cpm) and 1,065 cpm were applied to differentiate between being sedentary and light PA and between light and moderate to vigorous PA (MVPA), respectively. Prevalence of cognitive impairment was defined using the Six-Item Screener (<4/6). Letter fluency, animal fluency, word list learning, and Montreal Cognitive Assessment (orientation and recall) were used to assess memory and executive function. Results Of 7,098 participants (aged 70.1 ± 8.5, 54.2% female, 31.5% black), 359 (5.1%) had impaired cognition within ±12 months of PA measurement. The average proportion of time spent in MVPA (MVPA%) was 1.4 ± 1.9%. Participants in the highest quartile of MVPA% (~258.3 min/wk) were less likely to be cognitively impaired than those in the lowest quartile (odds ratio = 0.65, 95% confidence interval = 0.43-0.97). MVPA% was also significantly associated with executive function and memory z-scores ( P < .001). Similar analyses of proportion of time spent in light PA (LPA%) and sedentary time (ST%) showed no significant associations with cognitive function. Conclusion Higher levels of objectively measured MVPA%, rather than LPA% or ST%, were associated with lower prevalence of cognitive impairment and better performance in memory and executive function in aging people. The amount of MVPA associated with lower prevalence of cognitive impairment is consistent with meeting PA guidelines. [ABSTRACT FROM AUTHOR]

Using a sample of 2925 stroke-free participants drawn from a national population-based study, we examined cross-sectional associations of obstructive sleep apnea ( OSA) risk with cognition and quality of life and whether these vary with age, while controlling for demographics and comorbidities. Included participants from the REasons for Geographic And Racial Differences in Stroke ( REGARDS) study were aged 47-93 years. OSA risk was categorized as high or low based on responses to the Berlin Sleep Questionnaire. Cognitive function was assessed with standardized fluency and recall measures. Depressive symptoms were assessed with the four-item Center for Epidemiologic Studies Depression Scale. Health-related quality of life ( HRQo L) was assessed with the Medical Outcomes Study Short Form-12 ( SF-12). Multivariate analyses of covariance ( mancova) statistics were applied separately to the cognitive and quality of life dependent variables while accounting for potential confounders (demographics, comorbidities). In fully adjusted models, those at high risk for OSA had significantly lower cognitive scores ( Wilks' lambda = 0.996, F
3,2786 = 3.31, P < 0.05) and lower quality of life [depressive symptoms and HRQo L] ( Wilks' lambda = 0.989, F3,2786 = 10.02, P < 0.0001). However, some of the associations were age-dependent. Differences in cognition and quality of life between those at high and low obstructive sleep apnea risk were most pronounced during middle age, with attenuated effects after age 70 years.

Objective: State-level estimates of obesity based on self-reported height and weight suggest a geographic pattern of greater obesity in the Southeastern US; however, the reliability of the ranking among these estimates assumes errors in self-reporting of height and weight are unrelated to geographic region. Design and Methods: Regional and state-level prevalence of obesity (body mass index ≥ 30 kg m
−2 ) for non-Hispanic black and white participants aged 45 and over were estimated from multiple sources: self-reported from the behavioral risk factor surveillance system (BRFSS 2003-2006) ( n = 677,425), self-reported and direct measures from the National Health and Nutrition Examination Study (NHANES 2003-2008) ( n = 6,615 and 6,138, respectively), and direct measures from the REasons for Geographic and Racial Differences in Stroke (REGARDS 2003-2007) study ( n = 30,239). Results: Data from BRFSS suggest that the highest prevalence of obesity is in the East South Central Census division; however, direct measures suggest higher prevalence in the West North Central and East North Central Census divisions. The regions relative ranking of obesity prevalence differs substantially between self-reported and directly measured height and weight. Conclusions: Geographic patterns in the prevalence of obesity based on self-reported height and weight may be misleading, and have implications for current policy proposals.

Objectives To evaluate the association between six nondisease-specific problems (problems that cross multiple domains of health) and mortality in middle-aged and older adults. Design Prospective, observational cohort. Setting U.S. population sample. Participants Participants included 23,669 black and white U. S. adults aged 45 and older enrolled in the REasons for Geographic and Racial Differences in Stroke ( REGARDS) study. Measurements Nondisease-specific problems included cognitive impairment, depressive symptoms, exhaustion, falls, impaired mobility, and polypharmacy. Age-stratified (<65, 65-74, ≥75) hazard ratios for all-cause mortality were calculated for each problem individually and according to number of problems. Results One or more nondisease-specific problems occurred in 40% of participants younger than 65, 45% of those aged 65 to 74, and 55% of those aged 75 and older. Compared with participants with none of these problems, the multivariable adjusted hazard ratio for all-cause mortality associated with each additional nondisease-specific problem was 1.34 (95% confidence interval (CI) = 1.23-1.46) for participants younger than 65, 1.24 (95% CI = 1.15-1.35) for those aged 65 to 74, and 1.30 (95% CI = 1.21-1.39) for those aged 75 and older. Conclusion Nondisease-specific problems were associated with mortality across a wide age spectrum. Future studies should explore whether treating these problems will improve survival and identify innovative healthcare models to address multiple nondisease-specific problems simultaneously.

- Abstract
Objective: Examine whether long- and short-term sunlight radiation is related to stroke incidence. Methods: Fifteen-year residential histories merged with satellite, ground monitor, and model reanalysis data were used to determine sunlight radiation (insolation) and temperature exposure for a cohort of 16,606 stroke and coronary artery disease-free black and white participants aged ≥45 years from the 48 contiguous United States. Fifteen-, 10-, 5-, 2-, and 1-year exposures were used to predict stroke incidence during follow-up in Cox proportional hazard models. Potential confounders and mediators were included during model building. Results: Shorter exposure periods exhibited similar, but slightly stronger relationships than longer exposure periods. After adjustment for other covariates, the previous year's monthly average insolation exposure below the median gave a hazard ratio (HR) of 1.61 (95% confidence interval [CI], 1.15-2.26), and the previous year's highest compared to the second highest quartile of monthly average maximum temperature exposure gave an HR of 1.92 (95%, 1.27-2.92). Interpretation: These results indicate a relationship between lower levels of sunlight radiation and higher stroke incidence. The biological pathway of this relationship is not clear. Future research will show whether this finding stands, the pathway for this relationship, and whether it is due to short- or long-term exposures. ANN NEUROL 2013 [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To determine whether incidence of impaired cognitive screening status is higher in the southern Stroke Belt region of the United States than in the remaining United States. Methods: A national cohort of adults age ≥45 years was recruited by the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study from 2003 to 2007. Participants' global cognitive status was assessed annually by telephone with the Six-Item Screener (SIS) and every 2 years with fluency and recall tasks. Participants who reported no stroke history and who were cognitively intact at enrollment (SIS >4 of 6) were included (N = 23,913, including 56% women; 38% African Americans and 62% European Americans; 56% Stroke Belt residents and 44% from the remaining contiguous United States and the District of Columbia). Regional differences in incident cognitive impairment (SIS score ≤4) were adjusted for age, sex, race, education, and time between first and last assessments. Results: A total of 1,937 participants (8.1%) declined to an SIS score ≤4 at their most recent assessment, over a mean of 4.1 (±1.6) years. Residents of the Stroke Belt had greater adjusted odds of incident cognitive impairment than non-Belt residents (odds ratio, 1.18; 95% confidence interval, 1.07-1.30). All demographic factors and time independently predicted impairment. Interpretation: Regional disparities in cognitive decline mirror regional disparities in stroke mortality, suggesting shared risk factors for these adverse outcomes. Efforts to promote cerebrovascular and cognitive health should be directed to the Stroke Belt. ANN NEUROL 2011 [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Black individuals younger than 75 years have more than twice the risk for stroke death than whites in the United States. Regardless of race, stroke death is approximately 50% greater in the "stroke belt" and "stroke buckle" states of the Southeastern United States. We assessed geographic and racial differences in estimated 10-year stroke risk.Methods: The Reasons for Geographic and Racial Differences in Stroke study is a population-based cohort of men and women 45 years or older, recruited February 2003 to September 2007 at this report, with oversampling of stroke belt/buckle residents and blacks. Racial and regional differences in the Framingham Stroke Risk Score were studied in 23,940 participants without previous stroke or transient ischemic attack.Results: The mean age-, race-, and sex-adjusted 10-year predicted stroke probability differed slightly across regions: 10.7% in the belt, 10.4% in the buckle, and 10.1% elsewhere (p <0.001). Geographic differences were largest for the score components of diabetes and use of antihypertensive therapy. Blacks had a greater age- and sex-adjusted mean 10-year predicted stroke probability than whites: 12.0 versus 9.2%, respectively (p <0.001). Race differences were largest for the score components of hypertension, systolic blood pressure, diabetes, smoking, and left ventricular hypertrophy.Interpretation: Although blacks had a greater predicted stroke probability than whites, regional differences were small. Results suggest that interventions to reduce racial disparities in stroke risk factors hold promise to reduce the racial disparity in stroke mortality. The same may not be true regarding geographic disparities in stroke mortality. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective To assess risk factors associated with care for stroke symptoms. Methods Using data from the population-based national cohort study ( REasons for Geographic And Racial Differences in Stroke) conducted January 25, 2003-February 28, 2007 (N = 23,664), we assessed care-seeking behavior among 3,668 participants who reported a physician diagnosis of stroke/transient ischemic attack (n = 647) or stroke symptoms (n = 3,021) during follow-up. Care seeking was defined as seeking medical attention after stroke symptoms or a physician diagnosis. Results Overall, 58.5% of participants (2,146/3,668) sought medical care. In multivariable models, higher income was associated with greater likelihood of seeking care ( p = 0.02): participants with income of ≥$75,000 had odds 1.43 times (95% confidence interval [CI], 1.02-2.02) greater than those with income of less than $20,000. Diabetes and previous heart disease were associated with increased care seeking: odds ratio (OR) of 1.23 (95% CI, 1.04-1.47) and OR of 1.26 (95% CI, 1.06-1.49), respectively. Participants with previous stroke symptoms but no stroke history were less likely to seek care than those with stroke history or without previous symptoms (OR, 0.80; 95% CI, 0.67-0.96). Past smoking was associated with lower likelihood (OR, 0.71; 95% CI, 0.59-0.85; p = 0.0003) of seeking care relative to nonsmokers. Interpretation Only approximately half of participants with stroke symptoms sought care. This is despite the encouragement of advocacy groups to seek prompt attention for stroke symptoms. Our results highlight the importance of identifying characteristics associated with care-seeking behavior. Recognizing factors that contribute to delays provides opportunities to enhance education on the importance of seeking care for stroke symptoms. Ann Neurol 2008 [ABSTRACT FROM AUTHOR]
