title: Intermittent lack of health insurance coverage and use of preventive services.
abstract: OBJECTIVE
  This study examined the association between intermittent lack of health insurance coverage and use of preventive health services.
  
  
  METHODS
  Analyses focused on longitudinal data on insurance status and preventive service use among a national sample of US adults who participated in the Health and Retirement Study.
  
  
  RESULTS
  Findings showed that, among individuals who obtain insurance coverage after histories of intermittent coverage, relatively long periods may be necessary to reestablish clinically appropriate care patterns. Increasing periods of noncoverage led to successively lower rates of use of most preventive services.
  
  
  CONCLUSIONS
  Intermittent lack of insurance coverage-even across a relatively long period-results in less use of preventive services. Studies that examine only current insurance status may underestimate the population at risk from being uninsured.
