Trends in colorectal cancer test use among vulnerable populations in the United States.

Background: Evaluating trends in colorectal cancer (CRC) screening use is critical for understanding screening implementation, and whether population groups targeted for screening are receiving it, consistent with guidelines. This study examines recent national trends in CRC test use, including among vulnerable populations.

Methods: We used the 2000, 2003, 2005, and 2008 National Health Interview Survey to examine national trends in CRC screening use overall and for fecal occult blood test (FOBT), sigmoidoscopy, and colonoscopy.

Correlates of unrealistic risk beliefs in a nationally representative sample.

Unrealistically optimistic or pessimistic risk perceptions may be associated with maladaptive health behaviors. This study characterized factors associated with unrealistic optimism (UO) and unrealistic pessimism (UP) about breast cancer. Data from the 2005 National Health Interview Survey were analyzed (N = 14,426 women).

Health limitations and quality of life associated with cancer and other chronic diseases by phase of care.

Objective: To estimate health limitations and health-related quality of life (HRQL) associated with cancer and other chronic conditions in a nationally representative sample within a phase-of-care framework.

Study Design And Setting: We used a nested case-control design to assess health limitations and HRQL in individuals reporting a breast, colorectal, prostate, or lung cancer diagnosis, or a diagnosis of arthritis, diabetes, heart disease, or hypertension compared with similar controls without these conditions. All subjects were selected from the 1986-1994 National Health Interview Surveys linked to mortality files in 1995, and classified into the initial, continuing, or last year of life phase of care.
