  1. Select fatty acids used as substrate and product of D5D and D6D desaturase indices. The * denotes p-values which are significant (<0.05). P-values were determined using Student’s t-test and multiple linear regression (MLR) models which were adjusted for BMI, age, dietary LA, ALA, EPA and DHA, % total energy from dietary fat and physical activity. Caucasian males: n = 113; Caucasian females: n = 298; East Asian Males: n = 98; East Asian Females: n = 277. Abbreviation: SD standard deviation.
