Weight Loss Disparities Among Hispanic and Underserved Participants, Colorado, 2015–2018

PEER REVIEWED

An initial 2,770 participants, aged 18 years or older, were identified from 11 organizations enrolled in the National Diabetes Prevention Program and attended at least 1 National Diabetes Prevention Program session from July 1, 2015 through June 30, 2018. From those 2,770 participants, 1,337 participants were determined to be ineligible with less than 12 months’ opportunity for enrolling in the national program, leaving a total of 1,433 participants from 9 organizations. These participants had the opportunity to attend the national program for 12 months from the first session attended until the end of data collection. Of the 1,433 participants, 92 were ineligible based on missing prediabetes diagnoses, leaving 1,341 participants. Of the 1,341 participants, 133 were ineligible because they had less than 2 weight measurements, leaving 1,208 eligible participants from 9 organizations who had 2 or more weight measurements on record. From these, 106 participants were ineligible because of missing physical activity measurements, leaving 1,102. Fifty-seven participants were then excluded based on gestational diabetes diagnoses, leaving 1,045. Three of the 1,045 participants were excluded based on missing demographic data. Of the 1,042 remaining who met inclusion criteria and had complete demographic data, 35 participants were excluded because they did not meet the attendance threshold (attended 1 to 3 program sessions), leaving an analyzed sample of 1,007 participants who met the attendance threshold (4 to 30 sessions).
