title: Different effects of multiple health status indicators on breast and colorectal cancer screening in a nationally representative US sample.
abstract: OBJECTIVE
  To examine the independent associations between multiple health status indicators and breast and colorectal cancer screening (CRCS) in a national US sample.
  
  
  METHODS
  Analysis of cross-sectional data from the 2005 National Health Interview Survey (NHIS) involved 5115 men and 7100 women aged 50 years and older.
  
  
  METHODS
  Health status indicators included: self-reported perceived health status, number of chronic conditions, and functional limitation due to a chronic condition. Individuals were considered adherent to CRCS guidelines if they reported having a home-based fecal occult blood test in the past year or endoscopy in the past 10 years. Women were adherent to breast cancer screening guidelines if they reported having a mammogram in the previous 2 years. Statistical analyses were conducted using SUDAAN software to account for the complex sampling of the NHIS survey. Logistic regression was used to examine associations between each of the health status indicators and screening adherence for CRCS and mammography and to calculate estimated screening rates.
  
  
  RESULTS
  The three health status indicators were independently and differentially associated with screening adherence. Poor perceived health was associated with lower mammography among women, whereas a greater number of chronic conditions were consistently associated with greater screening. In adjusted analyses, functional limitation was only significantly associated with greater CRCS among women.
  
  
  CONCLUSIONS
  Our analyses included three common indicators of health status and provide new evidence of their complex associations with cancer screening. Future studies must examine the mechanisms by which these indicators influence screening recommendations and adherence among older adults over time.
