title: Leadership matters:  local health department clinician leaders and their relationship to decreasing health disparities.
abstract: OBJECTIVE
  The activities that local health departments (LHDs) conduct and their workforce characteristics change over time. We know little, however, about how changes among the services LHDs conduct are associated with the nature of LHD leadership and how these factors impact health. This study investigated changes in LHD services and leadership and how these changes are associated with mortality disparities.
  
  
  METHODS
  We conducted regression analyses of secondary data using an exploratory panel time series design.
  
  
  METHODS
  We used secondary data to investigate changes in LHD services and leadership and how these changes were associated with each other and with 1993 to 2005 changes in black-white mortality disparities. Local health department services were examined relative to change in breadth of services within each of 10 program domains between 1993 and 2005. LHD leadership was examined for discipline of the lead executive in 1993 and 2005.
  
  
  METHODS
  Our sample included 558 county or multicounty "common local areas," representing county-level data for LHDs and their jurisdictions.
  
  
  RESULTS
  Significant beneficial relationships exist between having a clinician as lead executive in an LHD and reductions in black-white mortality disparities. Local health departments with a clinician (usually a nurse or physician) as their lead executive in 1993 and/or 2005 experienced a significant decrease in black-white mortality disparities for young adults (age 15-44 years) in their jurisdictions from 1993 to 2005 when compared with LHDs with nonclinician leaders.
  
  
  CONCLUSIONS
  The discipline of an LHD's lead executive as a clinician appears to have a significant relationship with the impact of LHD practice on reducing black-white mortality disparities. This study suggests that the discipline of an LHD's leadership may be an important factor to consider in relation to local public health capacity to impact health disparities. Further research related to the mechanisms at play in these relationships is warranted.
