Thirty percent of Maine adults are obese, according to a Robert Woods Johnson Foundation report. Using data from the Centers for Disease Control, the foundation ranked states based on the CDC’s Behavioral Risk Factor Surveillance System which surveyed adults, asking them for their heights and weights.

The data provided by RWJF show a steady increase in almost every state’s obesity rates from, 1990 to the latest year, 2015. For the first time in the past decade a few states (Minnesota, Montana, New York and Ohio) registered decreases.

The lowest obesity rate in the nation was Colorado (20.2%) and the highest was Louisiana which, along with Mississippi, West Virginia and Alabama had a rate above 35%.

Massachusetts had the lowest rate (24.3%) of obese adults in New England in 2015 followed by Vermont (25.1%), Connecticut (25.3%), Rhode Island (26%) and New Hampshire (26.3%).
