• Description:
  Introduction:
  
  This study aimed to evaluate the trends in the impact of Medicaid expansion on the use of selected recommended clinical preventive services (CPSs) and examine differences in use by income level over time.
  
  Methods:
  
  The data were obtained from the 2011–2019 Behavioral Risk Factor Surveillance System and were analyzed in 2021. This study conducted a difference-in-differences analysis of the association between Medicaid expansion and the use of five CPSs, including colon/breast/cervical cancer screenings, HIV testing and influenza vaccination. Annual percent change was applied to assess the trends in the impact of Medicaid expansion on the use of CPSs.
  
  Results:
  
  The use of all five CPSs varied over time. In almost every year, the use of four CPSs (all but HIV testing) among Medicaid expansion states was higher than that among the non-expansion states. People with lower income used four CPSs (all but HIV testing) less frequently than those with higher income, regardless of their residence in expansion or non-expansion groups. Among the lower-income group, the use of five CPSs increased after Medicaid expansion almost every year with the use of colon cancer screening and HIV testing reaching statistical significance, and the impact of Medicaid expansion in the use of each CPS kept stable from 2014–2019.
  
  Conclusions:
  
  Our findings provide evidence that Medicaid expansion may be associated with sustainably increased use of the selected recommended CPSs among the lower-income population and that Medicaid expansion to reduce financial barriers may be an effective strategy to improve population health.
