Population-based studies from Medicare and privately insured individuals have consistently identified lower rates of colorectal cancer-screening tests among African-American versus white individuals. The purpose of this study was to evaluate whether, at a Veterans Affairs (VA) medical center, similar racial/ethnic differences in colorectal cancer screening could be identified. ⋯ In contrast to other settings, in a general medicine clinic at a VA hospital, rates of colorectal cancer-screening tests were not lower for African-American patients compared to white patients.

Several physical activity measures used in U.S. surveillance systems lack estimates of reliability in this country. This information is needed among diverse populations of women and men, to aid in interpretation and use of the measures. The objective of this study was to document the test-retest reliability of several measures of physical activity and inactivity used in surveillance in a diverse adult population. ⋯ In conclusion, this study provides estimates of test-retest reliability for several physical activity and inactivity measures used for surveillance purposes. Validity data, coupled with the reliability estimates reported here and elsewhere, can aid in interpretation and use of these measures in surveillance, as well as in epidemiologic studies.

Infectious acute respiratory disease (ARD) is a significant cause of worldwide morbidity, disproportionately affecting individuals living in crowded conditions, such as found at military training centers, school dormitories, and correctional facilities. Vaccines have been used to protect against ARD; however, these are not always available or effective. ⋯ Promoting hand hygiene and reducing crowding through the provision of adequate living space and cohorting of training units may offer benefits in respiratory disease control. These interventions, along with UV lights and air dilution/ventilation, deserve further evaluation in controlled studies to assess their efficacy. NOVARDIs could benefit military and other populations living in close contact.
