Nutrition studies were undertaken with two cohorts of White Mountain Apache preschool children, first in 1969 and again in 1976. Under the direction of the same investigator, similar procedures were used in the two studies to evaluate dietary, clinical, and biochemical status. The proportion of children in 1976 with low intakes of calories and of several micronutrients (calcium, vitamin A, vitamin C, thiamin, and iron) and with abnormal biochemical values (hemoglobin, serum iron, vitamin A, and vitamin C), was about half that in 1969. Height for age and weight for age were the same in the two studies. Skinfold thickness were slightly greater in 1976. Overall, these changes in nutritional status were in keeping with changes in the environment and in the economic and health care situations on the Fort Apache Reservation.
针对两组白山阿帕契学龄前儿童开展了营养研究，首次研究于1969年进行，再次研究于1976年进行。在同一位研究者的指导下，两项研究采用了相似的程序来评估饮食、临床和生化状况。1976年，热量和几种微量营养素（钙、维生素A、维生素C、硫胺素和铁）摄入量低且生化值异常（血红蛋白、血清铁、维生素A和维生素C）的儿童比例约为1969年的一半。两项研究中年龄别身高和年龄别体重相同。1976年皮褶厚度略大。总体而言，这些营养状况的变化与阿帕契堡保留地的环境、经济和医疗状况的变化相一致。
