The error in self-reported weight and height compared with measured weight and height was evaluated in a nationally representative sample of 11,284 adults aged 20-74 y from the second National Health and Nutrition Examination Survey of 1976-1980. Although weight and height were reported, on the average, with small errors, self-reported weight and height are(More)
There is a potential for nonresponse bias in most population studies using health examinations. This is true of the Mexican American portion of the Hispanic Health and Nutrition Examination Survey (HHANES), conducted by the National Center for Health Statistics, in which unit nonresponse to the examination accounted for 24 percent of the sample. Even though(More)
PURPOSE To investigate the prevalence of age-related maculopathy in three racial/ethnic groups, non-Hispanic whites, non-Hispanic blacks, and Mexican Americans. METHODS People 40 years of age or older who participated in a nationally representative population-based sample of the Third National Health and Nutrition Examination Survey were examined from(More)
This article focuses on changes in prevalence of three of the major risk factors for coronary heart disease (CHD) among the black population aged 25 to 74 years: blood pressure, cigarette smoking, and serum cholesterol. It also examines the extent to which changes in these risk factors might explain changes in observed CHD mortality. These national(More)
The goal of most current Unmanned Air Vehicle (UAV) research is to develop algorithms which allow a single agent or possibly a team of agents to operate completely autonomously without human interaction. Most of these autonomous algorithms operate at a high, strategic level and assume that low level tasks such as state stabilization and signal tracking have(More)
OBJECTIVE To compare the risk for diabetic retinopathy in non-Hispanic white, non-Hispanic black, and Mexican-American adults with type 2 diabetes in the U.S. population. RESEARCH DESIGN AND METHODS Representative population-based samples of people aged > or = 40 years in each of the three racial/ethnic groups were studied in the 1988-1994. Third National(More)
Three-dimensional (3D) fibrous hydrogels were fabricated by blending two photoactive polymers, poly(ethylene glycol) diacrylate (PEGDA) and poly(vinyl alcohol) (PVA), and the resulting solution was electrospun. PEGDA is a commonly used hydrogel material for tissue engineering applications since its interaction with cells can be tuned by crosslinking in a(More)
This report presents an investigation of potential nonresponse bias in the Hispanic Health and Nutrition Examination Survey (HHANES) conducted during the period 1982-84. Data from a household and medical history interview were used to investigate factors related to examination status. The study includes a comparison of data for examinees in HHANES with data(More)
