De-implementing public health policies: a qualitative study of the process of implementing and then removing body mass index (BMI) report cards in Massachusetts public schools.

Numerous factors contributed to the de-implementation of the policy.

Public health research should further focus on how to de-implement policy interventions when evidence is lacking or there is potential for harm.
