PURPOSE Staphylococcus aureus is a common cause of invasive infections, yet most assessments of prevalence are based on health care-based samples. We computed population-based estimates of nasal carriage of S aureus and risk factors for carriage, as well as population-based estimates of nasal carriage of methicillin-resistant S aureus (MRSA). METHODS We used the National Health and Nutrition ...

PC graphics technology, primarily driven by the video gaming industry, is becoming a possibility for the development of advanced virtual reality environments. The graphics and computational power required for virtual environments has been previously available exclusively on highend computing systems. Clustering multiple PCs to develop multi-processor multi-graphics systems capable of running an...

Researchers have long viewed large, longitudinal studies as essential for understanding chronic illness and generally superior to cross-sectional studies. In this study, we show that (1) age-specific arthritis prevalence in the longitudinal Health and Retirement Study (HRS) from the United States has risen sharply since its inception in 1992, and (2) this rise is almost surely spurious. In peri...

BACKGROUND The Behavioral Risk Factor Surveillance System (BRFSS) is a network of health-related telephone surveys--conducted by all 50 states, the District of Columbia, and participating US territories-that receive technical assistance from CDC. Data users often aggregate BRFSS state samples for national estimates without accounting for state-level sampling, a practice that could introduce bia...

A wave of Haitian immigration into Brazil began in February 2010 through three northern border states: Acre, Rondônia, and Amazonas. Focusing on the state of Amazonas, the article uses an ethnographic approach to explore the social networks involved in this immigrant issue and examines how Brazil’s Sistema Único de Saúde (SUS) responded to the demands placed by this unexpected contingent of new...

Obesity prevalence varies by income and education level, although patterns might differ among adults and youths (1-3). Previous analyses of national data showed that the prevalence of childhood obesity by income and education of household head varied across race/Hispanic origin groups (4). CDC analyzed 2011-2014 data from the National Health and Nutrition Examination Survey (NHANES) to obtain e...

This report presents national anthropometric reference data based on health examination survey results from the National Health and Nutrition Examination Survey (NHANES), 1999-2002, for all ages of the U.S. population. Weighted population means, standard errors of the means, and selected percentiles are presented for the total U.S. population by sex, race or ethnic group, and age in years or ag...

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...
