In Massachusetts, more overweight children are losing weight and violent crime has dipped, but much remains to be done in those and other health-related concerns, including drug abuse, according to the Massachusetts Health Council, which released its seventh statewide wellness report Tuesday.

“Clearly this report tells us, it’s a map, of what remains to be done. . . . We’ve come a long way, but we have a lot of work to do,’’ state Senator Harriette Chandler, a co-chair of the Prevention on Health Caucus, said during an event at the State House marking the release of the report, called Common Health for the Commonwealth.
