Graded associations between breakfast frequency and risk markers were observed ; children who reported not usually having breakfast had higher fasting insulin ( percent difference 26.4 % , 95 % CI 16.6 % -37.0 % ) , insulin resistance ( percent difference 26.7 % , 95 % CI 17.0 % -37.2 % ) , HbA1c ( percent difference 1.2 % , 95 % CI 0.4 % -2.0 % ) , glucose ( percent difference 1.0 % , 95 % CI 0.0 % -2.0 % ) , and urate ( percent difference 6 % , 95 % CI 3 % -10 % ) than those who reported having breakfast daily ; these differences were little affected by adjustment for adiposity , socioeconomic status , and physical activity levels .
