Publication Description
To describe usual dietary intake assessment at baseline and 1-year post-randomization in the ethnically diverse Diabetes Prevention Program cohort. Participants were randomized to Lifestyle Modification, Metformin, or Placebo. Usual diet was assessed by a modified, previously validated food frequency interview. Complete data were available for 2934 subjects (90.7% of those randomized). Baseline median estimated energy intake was 7676 kJ/d (1828 kcal/d) and 8585 kJ/d (2044 kcal/d) for women and men, respectively. The median percent of energy from fat ranged from 30.6% for Asian American men to 37.5% for American Indian men and women. After 1 year among the Lifestyle group, the median change in total energy and percent energy from fat was −1897 kJ/d (−452 kcal/d) and −6.6%, respectively. For the Metformin and Placebo groups, change in median total energy was −1235 kJ/d (−294 kcal/d) and −1051 kJ/d (−250 kcal/d), respectively, and change in median percent energy from fat was −0.8% and −0.8%, respectively (
