Obesity results from a complex interaction between diet, physical activity, and the environment. The built environment encompasses a range of physical and social elements that make up the structure of a community and may influence obesity. This review summarizes existing empirical research relating the built environment to obesity. The Medline, PsychInfo,(More)
In 21 patients who suffered aphasia resulting from left hemisphere ischemic infarction, the xenon 133 inhalation cerebral blood flow technique was used to measure cerebral blood flow within 3 months and 5 to 12 months after stroke. In addition to baseline measurements, cerebral blood flow measurements were also carried out while the patients were performing(More)
We designed, implemented and evaluated an educational intervention to increase fruit and vegetable consumption among urban African-American women. Women aged 20-50 years (n=212) from 11 public housing communities participated in seven 90-min classes with a professional nutritionist. Our prospective pre- and post-test design, with 4-month follow-up, assessed(More)
To study the regional cerebral blood flow (rCBF) correlates of auditory processing, we performed rCBF measurements in young, normal right-handed volunteers engaged in listening tasks. Using the xenon Xe 133 inhalation technique, rCBF was measured in 11 regions in each hemisphere. Compared with a baseline condition, significant rCBF increases in the left(More)
Background: Spatial variation in patterns of disease outcomes is often explored with techniques such as cluster detection analysis. In other types of investigations, geographically varying individual or community level characteristics are often used as independent predictors in statistical models which also attempt to explain variation in disease outcomes.(More)
BACKGROUND AND PURPOSE This study examined the effectiveness of a slide/audio community education program aimed at increasing knowledge of stroke risk factors, stroke warning signs, and action needed when stroke warning signs occur. The program targets audiences at higher risk for stroke, especially individuals who are black or >50 years of age. METHODS(More)
OBJECTIVES We studied school personnel involved in the review of student's immunization status to determine whether personnel training, immunization-related knowledge, attitudes, and beliefs, use of alternative medicine, and sources of vaccine information were associated with the vaccination status of school children. METHODS Surveys were mailed to a(More)
Respiratory rates and patterns were studied in 23 patients with acute brain stem infarction using impedance pneumography. Autopsy was obtained in six of eight fatal cases. Pontine lesions were present in all patients, with coexistent infarction of midbrain in four and of medulla in nine. Respiratory rate and pattern abnormalities observed included(More)
BACKGROUND The importance of geography as a source of variation in health research continues to receive sustained attention in the literature. The inclusion of geographic information in such research often begins by adding data to a map which is predicated by some knowledge of location. A precise level of spatial information is conventionally achieved(More)
