Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...

Previous research has demonstrated that married men are more likely than not-married men to seek preventive health care services because their spouses encourage them to do so (1,2). It was not known, however, whether cohabiting partners of not-married men play a health-promoting role similar to that of spouses. With data from the 2011-2012 National Health Interview Survey (NHIS), selected measu...

Background. The literature on colorectal cancer (CRC) screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS) respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses w...

This report presents a detailed description of the sample design for the Third National Health and Nutrition Examination Survey, 1988-94, including a brief description of research that led to the choice of the final design. The National Health and Nutrition Examination Survey (NHANES) is one of the major surveys of the National Center for Health Statistics, Centers for Disease Control. Informat...

It is possible to use different methods to weight National Health and Nutrition Examination Survey (NHANES) data. Typically when weighting NHANES data we use a weighting class approach of predefined cells based on a limited number of variables. However, there are model based alternatives that allow for more flexibility in calculating the statistical weights. This flexibility is important becaus...

Excessive pain during medical procedures performed in unanesthetized patients is frequently reported, but can be reduced with virtual reality (VR) distraction. Increasing the person's illusion of going into the virtual world may increase how effectively VR distracts pain. Healthy volunteers aged 18-20 years participated in a double-blind between-groups design. Each subject received a brief base...

The Longitudinal Study on Aging (LSOA) and the National Health Interview Survey (NHIS) are used to examine change in the prevalence of disability from 1982 through 1993 for persons 70 years of age and over. Changes in the likelihood of becoming disabled and the likelihood of recovering from disability also are investigated with the LSOA. There is some evidence for improving disability status am...
