Objective To determine trends in ischemic stroke incidence among Mexican Americans and non-Hispanic whites. Methods We performed population-based stroke surveillance from January 1, 2000 to December 31, 2010 in Corpus Christi, Texas. Ischemic stroke patients 45 years and older were ascertained from potential sources, and charts were abstracted. Neurologists validated cases based on source documentation blinded to ethnicity and age. Crude and age-, sex-, and ethnicity-adjusted annual incidence was calculated for first ever completed ischemic stroke. Poisson regression models were used to calculate adjusted ischemic stroke rates, rate ratios, and trends. Results There were 2,604 ischemic strokes in Mexican Americans and 2,042 in non-Hispanic whites. The rate ratios (Mexican American:non-Hispanic white) were 1.94 (95% confidence interval [CI] = 1.67–2.25), 1.50 (95% CI = 1.35– 1.67), and 1.00 (95% CI = 0.90–1.11) among those aged 45 to 59, 60 to 74, and 75 years and older, respectively, and 1.34 (95% CI = 1.23–1.46) when adjusted for age. Ischemic stroke incidence declined during the study period by 35.9% (95% CI = 25.9–44.5). The decline was limited to those aged ≥60 years, and happened in both ethnic groups similarly (p > 0.10), implying that the disparities seen in the 45- to 74-year age group persist unabated. Interpretation Ischemic stroke incidence rates have declined dramatically in the past decade in both ethnic groups for those aged ≥60 years. However, the disparity between Mexican American and non-Hispanic white stroke rates persists in those <75 years of age. Although the decline in stroke is encouraging, additional prevention efforts targeting young Mexican Americans are warranted.

Innovative strategies are needed to reduce the hypertension epidemic among African Americans. Reach Out was a faith-collaborative, mobile health, randomized, pilot intervention trial of four mobile health components to reduce high blood pressure (BP) compared to usual care. It was designed and tested within a community-based participatory research framework among African Americans recruited and randomized from churches in Flint, Michigan. The purpose of this pilot study was to assess the feasibility of the Reach Out processes. Feasibility was assessed by willingness to consent (acceptance of randomization), proportion of weeks participants texted their BP readings (intervention use), number lost to follow-up (retention), and responses to postintervention surveys and focus groups (acceptance of intervention). Of the 425 church members who underwent BP screening, 94 enrolled in the study and 73 (78%) completed the 6-month outcome assessment. Median age was 58 years, and 79% were women. Participants responded with their BPs on an average of 13.7 (SD = 10.7) weeks out of 26 weeks that the BP prompts were sent. All participants reported satisfaction with the intervention. Reach Out, a faith-collaborative, mobile health intervention was feasible. Further study of the efficacy of the intervention and additional mobile health strategies should be considered.

Background and Purpose: Our objective was to compare neurologic, functional, and cognitive stroke outcomes in Mexican Americans (MAs) and non-Hispanic whites (NHWs) using data from a population-based study. Methods: Ischemic strokes (2008-2012) were identified from the Brain Attack Surveillance in Corpus Christi (BASIC) Project. Data were collected from patient or proxy interviews (conducted at baseline and 90 days post-stroke) and medical records. Ethnic differences in neurologic (National Institutes of Health Stroke Scale (NIHSS), range 0-44, higher scores worse), functional (activities of daily living (ADL)/instrumental activities of daily living (IADL) score, range 1-4, higher scores worse), and cognitive (Modified Mini-Mental State Examination (3MSE), range 0-100, lower scores worse) outcomes were assessed with Tobit or linear regression adjusted for demographics and clinical factors. Results: 513, 510, and 415 subjects had complete data for neurologic, functional and cognitive outcomes and covariates, respectively. Median age was 66 (IQR: 57-78); 64% were MA. In MAs, median NIHSS, ADL/IADL and 3MSE score were 3 (IQR: 1-6), 2.5 (IQR: 1.6-3.5) and 88 (IQR: 76-94), respectively. MAs scored 48% worse (95% CI: 23%-78%) on NIHSS, 0.36 points worse (95% CI: 0.16-0.57) on ADL/IADL score, and 3.39 points worse (95% CI: 0.35-6.43) on 3MSE than NHWs after multivariable adjustment. Conclusions: MAs scored worse than NHWs on all outcomes after adjustment for confounding factors; differences were only partially explained by ethnic differences in survival. These findings in combination with the increased stroke risk in MAs suggest that the public health burden of stroke in this growing population is substantial.
