Data users often aggregate BRFSS state samples for national estimates without accounting for state-level sampling, a practice that could introduce bia...
Previous studies of survey data from the U.S. and other countries find that women tend to understate their body weight on average, while both men and women overstate their height on average. Social norms have been posited as one potential explanation for misreporting of weight and height, but lack of awareness of body weight has been suggested as an alternative explanation, and the evidence pre...
In 1989 an estimated 33.9 million persons in the civilian noninstitu tionalized population of the United States (13.9 percent) were reported to lack health care coverage. This point-prevalence estimate represents an average for 52 weeks of household interviews conducted by the U.S. Bureau of the Census for the National Health Interview Survey (NHIS). It is a measure of a person’s coverage stat...

A concise method for the preparation of new 3,4,5,6-tetrahydropyrimidinium salts was presented in this paper. Further application of these salts in asymmetric diethylzinc addition of arylaldehydes was explored, giving the corresponding chiral second alcohols in good yields and moderate enantioselectivities.
OBJECTIVES This report presents long-term trends in the number and percentage of persons under age 65 years with different types of health insurance coverage and with no coverage. It documents changes in how the National Health Interview Survey (NHIS) has collected information about coverage over almost 50 years. It also compares recent trends in coverage estimates based on the NHIS and the U.S...

Methods. Analysis was based on the 2010 National Health Interview Survey (NHIS). A total of 59,199 American adults provided valid data for the present analyses (mean a...
