Dr. Ronald M. Lauer, Department of Pediatrics, Dr. William E. Connor, Department of Internal Medicine, and their colleagues at The University of Iowa initiated The Muscatine Study on November 17, 1970 when the first school survey examinations were conducted at Grant Elementary School in Muscatine, Iowa. The initial purpose of The Muscatine Study was to define the distribution of established adult cardiovascular risk factors (body size, blood pressure and cholesterol levels) in school-aged children and to characterize the tracking of risk factor levels throughout childhood into adulthood. Between 1970 and 1981, 11,377 students from Muscatine participated up to six biennial school survey examinations; 38% participated in one and 23% participated in four to six examinations. The Muscatine Study is the longest running study of cardiovascular risk factors in children in the United States. Many of the earliest school survey participants, along with their children and grandchildren, still participate in Muscatine Study examinations.
