Note: ILI= Intensive Lifestyle Intervention. Within columns and demographic groupings, values with different superscripts (i.e., a, b, c, etc.) differ significantly from each other (p < 0.05). For example, at year 1, men lost significantly more weight than women (“a” vs “b”). At year 4, there were no significant differences between men and women, as shown by the shared superscript “a.” At year 2, the “a” superscript for Non-Hispanic Whites indicates that they lost significantly more weight than participants who were African American and American Indian/Other, each of whom had “c” superscripts. By contrast, Hispanic Americans did not differ significantly from African Americans, as shown by their shared superscript “b.” All analyses are adjusted for clinical site and baseline weight. Each family of comparisons was conducted using the Bonferroni correction.

At year 4, non-Hispanic white men and women lost (mean ± SE) 5.3 ± 0.3 and 4.6 ± 0.3% of initial weight, respectively, whereas Hispanic men and women lost 4.0 ± 0.8 and 5.5 ± 0.6%, respectively. African-American men and women lost 2.8 ± 0.7 and 4.4 ± 0.5%, respectively. Comparable values for American Indian/Other participants were 4.2 ± 0.9 and 3.5 ± 0.7%, respectively.
