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...

The present study investigates whether a virtual reality (VR) intervention can influence pain catastrophizing, pain self-efficacy and other pain-related measures reported during a cold-pressor experience. Forty-five healthy participants underwent two consecutive cold-pressor trials, one using VR and one without VR exposure, in counterbalanced order. The VR intervention encouraged participants t...

OBJECTIVES Using linked administrative data, to validate Medicare coverage estimates among adults aged 65 or older from the National Health Interview Survey (NHIS), and to assess the impact of a recently added Medicare probe question on the validity of these estimates. DATA SOURCES Linked 2005 NHIS and Master Beneficiary Record and Payment History Update System files from the Social Security ...

OBJECTIVE To examine trends in the prevalence of type 2 diabetes and related conditions in Asian Americans compared with non-Hispanic whites. RESEARCH DESIGN AND METHODS We analyzed data from the National Health Interview Survey (NHIS) from 1997 to 2008 to construct a nationally representative sample of 230,503 U.S. adults aged ≥ 18 years. Of these adults, 11,056 identified themselves as Asia...

OBJECTIVES There is growing interest in engaging patients in healthcare research, which raises important questions about the factors that may promote such engagement. The purpose of this study was to examine the association between patient characteristics and three aspects of patient engagement in the medical research process: awareness, interest, and actual participation. METHODS Cross-secti...
