Dietary intake was assessed at baseline using the National Cancer Institute’s (NCI) diet history questionnaire-II (DHQ-II) (We analyzed the intake of the following 21 micronutrients: choline, folic acid, niacin, riboflavin, thiamin, vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin D, vitamin E, calcium, chromium, copper, iodine, iron, magnesium, manganese, potassium, selenium, and zinc and the supplement intake of iodine and chromium. Because the results of the DHQ-II and NDSR have not been compared, the dietary intake obtained are reported separately for both methods.
