SECONDARY outcome

Timeframe: 6 months

Population: Data not collected for the Enhanced Usual Care Arm/Group as this was the comparator.

Cost effectiveness was calculated for the group as the average total cost of the intervention arm (GP or IP) divided by the average weight loss at 6 months of the intervention arm. Costs associated with delivering the 6-month weight loss intervention, including supplies and intervention implementation, were estimated in 2019 U.S. dollars. Supply costs, i.e., pedometers, participant notebooks, providing and shipping low-calorie shakes and printed materials for the GP and IP arms. Implementation costs, i.e., time devoted to interventionist training, preparation and delivery of behavioral sessions and email contacts with participants were estimated as the time spent in these activities obtained from interventionist time sheets multiplied by interventionists hourly wage. Due to the cost effectiveness outcome measure being a ratio between two random variables, there are no dispersion/precision measures reported.
