Weight management piot study

Description

A dataset containing information about a pilot study for weight management in individuals at risk for developing diabetes. The treatment group received additional weight management counseling from a physician's assitant during their regular doctor visits. The control group did not. The weight management counseling lasted for 6 months, at which time weight was recorded. Participants returned for a 12-month visit in which weight was recorded again. Any missing data in the 6 or 12 month visits were imputed using baseline observation carried forward. All variables with 0m suffix were recorded at baseline.
