Explanation of the Indicator
Obesity is a major contributor to cardiovascular disease, cancer and diabetes. It also negatively impacts public health costs and educational outcomes. A person is considered to be obese if their BMI (body mass index) is 30 or greater. BMI is weight (in kilograms) divided by height (in meters) squared.
In some cases, County-level data are not available from the same data source used by the State. In other cases, County-level data are not available for the same time frame used by the State. In these instances, data sources and time frames were selected that most closely match those of the State. Due to this difference, it must be noted that comparisons may not be completely equivalent in all cases. For this indicator, Michigan's data reflects annual obesity rates from 2006-2016. Ottawa's data reflects 5-year and 3-year moving average obesity rates because annual rates are not available for counties. Due to methodology changes that were implemented in 2011, the Behavioral Risk Factor Survey was not published for two years. Michigan's data source is the Centers for Disease Control and Prevention. Ottawa County’s data source is the
Michigan Department of Community Health, Behavioral Risk Factor Survey. When this page was last
updated in September 2018, 2016 data was the most recent data available from these sources.
