Missouri County-Level Study (CLS)
The Missouri County-level Study (CLS) was conducted in 2002-2003, 2007 and 2011 to produce county-specific prevalence estimates of chronic diseases, conditions, and risk factors. For each of the studies, Missouri Department of Health and Senior Services (MDHSS) staff was responsible for overseeing the study design and making the data available on the MDHSS Community Data Profiles web site. The University of Missouri-Columbia Health and Behavioral Risk Research Center was contracted to conduct interviews with Missouri adults age 18 and older for each study. The 2007 and 2011 studies were funded by the Missouri Foundation for Health.* ICF Macro was contracted to conduct the primary analysis for the 2007 and 2011 studies.
For the 2011 CLS, a total of 47,261 adults were interviewed via randomly selected landline telephone numbers. Additionally, 4,882 randomly selected cell phone-only adult users were interviewed.
The 2011 CLS data were weighted using a new methodology. For an explanation, go to “Information about the study design and methodology.” Because of the new weighting method, previous CLS data cannot be compared to 2011 data unless it is reweighted. In the near future, 2007-2011 Comparison Community Data Profiles will be made available on the DHSS website.
