ORIGINAL RESEARCH — Volume 17 — May 28, 2020
During the enrollment phase, 351 participants were assessed for eligibility. Of these, 193 people were excluded (did not meet inclusion criteria [n = 128], declined to participate [n = 26], did not attend orientation [n = 35], had incomplete consent [n = 4]), and 158 were randomly assigned. Eighty people were assigned to the VLM-DPP, and 78 were assigned to the YMCA-DPP. Of those in the VLM-DPP, 59 received the intervention, and 21 did not because of not completing any intervention session. Of those in the YMCA-DPP, 71 received the intervention, and 7 did not because of not completing any intervention session. In the VLM-DPP, 29 were lost to follow-up because they declined to continue, and in the YMCA-DPP, 13 were lost to follow-up because they declined to continue. Of participants who were analyzed in the VLM-DPP, 51 had measured weight, and 80 had either measured or imputed weight. Of participants who were analyzed in the YMCA-DPP, 65 had measured weight, and 78 had either measured or imputed weight.
