Nutrient intake of selected non-reservation native Americans residing in southwest Oregon

Graduation date: 1982A study of nutrient intakes was conducted on the Southwest\ud Oregon non-reservation Indian population during June and July of\ud 1980. Participating households were selected by random methods from\ud a Southwest Oregon Indian Health Project listing of Indian\ud households in the six-county area. Twenty-four-hour dietary recalls\ud were obtained by interview method from 504 individuals, representing\ud 226 Indian households; a food frequency questionnaire served as\ud a cross-check. Ages of the participants ranged from 1 to 81 years.\ud The dietary intakes, excluding supplements, of calories,\ud protein, calcium, iron, vitamin A, thiamin, riboflavin, niacin,\ud and ascorbic acid were computer analyzed for 13 age-sex groupings.\ud Mean and median nutrient intakes were compared to the 1980\ud Recommended Dietary Allowances (RDA) and discussed as meeting\ud 33.3 percent or less of the RDA, meeting 33.4 to 66.6 percent of\ud the RDA, meeting 66.7 to 99.9 percent of the RDA, or meeting\ud the RDA fully.\ud Iron was the nutrient found to be low most often, with\ud children ages 1 to 3 years and females 11 to 50 years having\ud mean intakes from 61 to 87 percent of the 1980 RDA. Calcium\ud intakes were low for all female groups age 11 years and beyond;\ud females 51 years and over had the lowest intakes compared to\ud the 1980 RDA.\ud Mean and median dietary intakes of protein, riboflavin,\ud and niacin were close to or in excess of the appropriate RDA\ud for all age-sex groups. Ascorbic acid and vitamin A were\ud consumed in adequate mean amounts, but there were large numbers\ud of low intakes in some age-sex groups.\ud Data concerning shopping habits, sources of food, food\ud aid, tribal affiliation(s), cooking and refrigeration adequacy,\ud consumption of "traditional" Indian foods, and income were\ud obtained by means of a household questionnaire. A comparison was\ud made between selected demographic factors and Household Diet\ud Scores, which were based on individual nutrient intakes compared\ud to the 1980 RDA.\ud Households which obtained food from a home garden and\ud households which canned or froze food for later use had significantly\ud higher (p [less than or equal to] .05) mean Household Diet Scores than did\ud households which did not have these characteristics. Income\ud levels and the practice of obtaining meat from hunting or from\ud fishing lacked a significant relationship to Household Diet\ud Scores at p [less than or equal to] 0.05.\ud The percentage contributions of carbohydrate, fat, and\ud protein to caloric intakes were: 45 percent from carbohydrate,\ud 39 percent from fat, and 16 percent from protein.\ud In general, the diets of the Southwest Oregon Native\ud American population were found to approximate the diets of the\ud general United States population as reported in the 1977-78\ud Nationwide Food Consumption Survey in relation to nutrient\ud intakes and caloric sources
