Abstract

The purpose of this study was to evaluate on nutrient intake status and diet quality of middle and old aged vegetarian women in Korea. The research group was composed of vegetarian women (n = 91), all of them were Seven Day Adventists, who had been on vegetarian diets, over 20 yrs. Their anthropometric measurements, dietary intakes, and diet quality indices were compared to omnivores (n = 122). The average age of vegetarians and omnivores were 61.8 yrs and 60.3 yrs, respectively. The mean daily energy intakes of vegetarians and omnivores were 1428.8 kcal and 1424.5 kcal, respectively and there was no significant difference. The vegetarians consumed significantly lower intakes of protein (p<0.05), zinc (p<0.001) and vitamin B2 (p<0.05) compared to omnivores. In the diet quality, zinc and vitamin B2 nutrient adequacy ratio (NAR) of vegetarians were significantly lower than those of omnivores. Mean adequacy ratio (MAR) of vegetarians and omnivores were 0.80 and 0.77, respectively and there was no significant difference. The KDDS (Korean's Dietary Diversity Score) of vegetarians and omnivores were 3.7 and 4.0, respectively, and there was significant difference (p<0.01). The KDQI (Korean's Diet Quality Index) of vegetarians (1.5) was significantly lower than that (2.1) of omnivores (p<0.001). In conclusion, vegetarian women have low intake status of protein, zinc and vitamin B2, and partly low diet quality. Therefore it was needed that well planed diets to replace the nutrients supplied from excluded food groups in middle and old aged vegetarian women.
