The Washtenaw childhood obesity surveillance project began in 2013. Through the Health Improvement Plan (HIP) collaborative, Washtenaw County Health Department worked with St. Joseph Mercy Health System and the Michigan Medicine to create the Washtenaw Child BMI Dataset. In the first year, both health systems contributed measured height and weight data from electronic health records for over 18,000 children, ages 2 to 17 years old, living in Washtenaw County. Each year since, the health systems contributed records from over 31,000 children each year, covering nearly 50% of children in Washtenaw County.
