We examined whether new policies restricting sales in schools of so-called competitive foods and beverages-those that fall outside of what is served through federally reimbursed school meal programs-influenced increasing rates of overweight children in the Los Angeles Unified School District and the rest of California. After these policies, which set(More)
Epidemiologic studies have observed influences of the food environment near schools on children's overweight status but have not systematically assessed the associations by race, sex, and grade. The authors examined whether the associations between franchised fast food restaurant or convenience store density near schools and overweight varied by these(More)
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.(More)
Mexican Americans (MAs), the largest subgroup of Hispanic Americans, have an increased stroke risk compared with non-Hispanic whites (NHWs) but experience less case fatality and longer poststroke survival. The finding of improved survival in MAs may give the false sense that MA stroke is less burdensome than stroke in NHWs, but it is possible that the(More)
BACKGROUND Physical education policies have received increased attention as a means for improving physical activity levels, enhancing physical fitness, and contributing to childhood obesity prevention. Although compliance at the school and district levels is likely to be critical for the success of physical education policies, few published studies have(More)
BACKGROUND AND PURPOSE Our objective was to identify factors that contribute to or modify the sex difference in poststroke functional outcome. METHODS Ischemic strokes (n=439) were identified from the Brain Attack Surveillance in Corpus Christi (BASIC) Project (2008-2011). Data were ascertained from interviews (baseline and 90 days post stroke) and(More)
BACKGROUND The prevalence of severe obesity is rising in the United States. Although mild to moderately elevated body mass index (BMI) is associated with reduced mortality after acute ischemic stroke, less is known about severe obesity. METHODS AND RESULTS Patients with acute ischemic stroke (n=1791) ≥45 years were identified from the biethnic(More)
OBJECTIVE To explore temporal trends in tissue plasminogen activator (tPA) administration for acute ischemic stroke (AIS) in a biethnic community without an academic medical center and variation in trends by age, sex, ethnicity, and stroke severity. METHODS Cases of AIS were identified from 7 hospitals in the Brain Attack Surveillance in Corpus Christi(More)
OBJECTIVE To evaluate the use and tolerability of noninvasive positive pressure ventilation (NIV) in patients with amyotrophic lateral sclerosis (ALS) early in their disease by comparing active NIV and sham NIV in patients not yet eligible for NIV use as recommended by practice guidelines. METHODS This was a single-center, prospective, double-blind,(More)
BACKGROUND A wide variety of racial and ethnic disparities in stroke epidemiology and treatment have been reported. Race-ethnic differences in initial stroke severity may be one important determinant of differences in the outcome after stroke. The overall goal of this study was to move beyond ethnic comparisons in the mean or median severity, and instead(More)
