  • *Differences across race/ethnicity groups were tested by ANOVA after adjusting for age, sex, and clinic site. African Americans had higher intake of mO-3FA, higher HDL, and lower triglycerides than Caucasians, Hispanics, and the other race/ethnicity group (P < 0.05 for all differences).

  • †Differences between intensive lifestyle intervention (ILI) and diabetes, support, and education (DSE) in variable change from baseline were evaluated using the unpaired t test. ILI participants had lower mO-3FAs, higher HDL, and lower triglycerides than individuals in DSE (P < 0.001 for all differences).

  • ‡Differences between ILI and DSE in the proportion of subjects eating fried fish/sandwich fish ≥1/week were tested with χ2. There was a greater decrease of fried fish/sandwich fish intake in ILI than in DSE (P < 0.001). Percent subjects eating lean fish >1/week increased by 5.54% with ILI and by 1.27% with DSE (P = 0.012). Change in percent subjects eating fish rich in mO-3FAs did not differ between ILI and DSE at 1 year (P = 0.421).
