This article reports data concerning the Internet-related activities and interest for Ironman Triathlon competition. Google Trends (GT) was used and mined from 2004 onwards. The interest for Ironman Triathlon was found to be cyclic over time. The Triathlon-related Internet activities negatively correlated with the number of finishers per year (Pearson׳s correlation r=-0.690, p-value<0.05), whil...

Studies have suggested that obesity prevalence varies by income and educational level, although patterns might differ between high-income and low-income countries (1-3). Previous analyses of U.S. data have shown that the prevalence of obesity varied by income and education, but results were not consistent by sex and race/Hispanic origin (4). Using data from the National Health and Nutrition Exa...

Research was undertaken to evaluate alternative methods of selecting a sample of eligible respondents for the National Medical Expenditure Survey (NM ES) from the National Health Interview Survey (N HIS). This report presents estimates of the effects of alternative design options, obtained by statistical modeling techniques, for linking the NMES with the NH IS, The estimated survey costs for al...

The Standard Model does not provide a very good fit to the most recent precision electroweak data from LEP, due primarily to the observed branching ratios for Z decay to bb̄ and cc̄. The possibility that an extension of the Standard Model with low-energy supersymmetry can improve the agreement between data and theory is considered. Invited Talk at the 1995 International Europhysics Conference on ...

Obesity is a public health challenge throughout the world. Ongoing monitoring of trends in obesity is important to assess interventions aimed at preventing or reducing the burden of obesity. Since the 1960s, measured height and weight have been collected in the United States as part of the National Health and Nutrition Examination Survey (NHANES). In Canada, data on measured height and weight h...

This study estimates the percentage of health care expenditures in the non-institutionalized United States (U.S.) adult population associated with levels of physical activity inadequate to meet current guidelines. Leisure-time physical activity data from the National Health Interview Survey (2004-2010) were merged with health care expenditure data from the Medical Expenditure Panel Survey (2006...

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...

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...

As medical information becomes increasingly available and individuals take a more active role in managing their personal health, it is essential for scholars to better understand the general public's information-seeking behavior. The study reported here explores the use of the World Wide Web to seek health information in a contemporary information-media environment. Drawing from uses and gratif...
