This study was conducted to find associations of obesity, exercise pattern and nutrient intakes in Korean American immigrants residing in North Western parts of USA. The structured survey forms and food frequency questionnaire that covered 67 food items were used. There was a significant difference in height for subjects by gender and age. However, the weight of females became heavier with increasing age in contrast to males. There was a great difference in BMI between the male and female group in the youngest adult group compared to the aging adults. Significant age difference in exercise pattern was shown. Dietary fiber and sodium intakes were higher in the elderly than young ones in female group. In the same young adult group Zn intakes was the highest in the male group and the lowest in the female group. Folate intakes were higher in females than in males. Strong positive correlations among height, weight and BMI were shown. Zn intake was significantly correlated with weight, height, and exercise pattern in the study. Furthermore, Zn was correlated with sodium, vitamin B6, folate, vitamin E and cholesterol.

This study was undertaken to investigate meal pattern, nutrition knowledge and food preference of 438 rural middle school students living in ChunNam area. As far as nutrition knowledge is concerned, most subjects did not answer correctly on the items of basic five food groups, animal fat and vegetable oil, empty source of soft drink, nutrient requirement and water's role in energy metabolism. However they responded well on the item of iron deficiency and dietary source of Ca. Male students were significantly better in the answering the items of dietary source of energy and nutrient requirement than females, while female students were significantly better on the items of water's role in energy metabolism related to obesity. Generally the respondents did neither consume oil often nor consider consumption of salty food. Furthermore, only 38.6% of subjects drink milk daily in spite of understanding dietary source of Ca, which suggested that they should incorporate nutrition knowledge into dietary behavior. The preferred foods for most subjects were fruit, kimbab and ice cream. Contrastingly the food that they did not prefer was fermented vegetable probably due to strong flavor.

Amish집단(미국 오하이오주 홈스카운터 거주)의 vitamin E 영양상태를 24시간 회상법, 영양보충제의 사용량 조사, colorimetric법에 의한 혈장 vitamin E의 분석으로 평가하였다. 평균식이 섭취 vitamin E는 7.4㎎ α-tocopherol equivalent였으며 평균 181.4 IU는 영양 보충제로 섭취했다. 전체 vitamin E의 67.7%는 식이를 통해 섭취했으며 32.4%는 영양 보충제를 복용함으로 섭취했다. 평균 혈장 vitamin E 농도는 13.4㎍/㎖였다. 혈장 vitamin E와 영양제로 복용한 vitamin E 사이에는 유의적인 상관관계가 (r=0.489, p=0.0001)를 보여주었고 혈장 vitamin E와 연령과도 상관관계 (r=0.216, p=0.0017)가 있었다. Amish 집단의 vitamin E 영양상태는 충분했으며 이 집단 중의 어떤 자들은 고단위의 다량의 vitamin E 영양제를 복용하고 있어 vitamin E에 대한 올바른 정보를 알려주고 효율적인 영양교육을 시킬 필요성이 요청되었다. In 70 male and female Amish residents of Holmes County, Ohio, USA adequacy of vitamin E was evaluated. Subjects were interviewed three times over a 1.5 year period. Dietary intake of vitamin E was determined from three twenty-four hour recalls with a food composition table. Information on supplements was obtained during the available interviews. From these data, total vitamin E was calculated. Blood samples obtained during interview were analyzed for plasma vitamin E by a colorimetric method. The mean dietary intake of vitamin E was 84% of the RDA(7.4㎎ α-T. E). The mean intake of supplements was 181.4 IU. The mean total vitamin E intake was 188.8 α-T. E. About 67.7% of the total vitamin E intake came from dietary sources, while 32.4% came from supplements. Mean plasma vitamin E concentration was 13.4㎍ /㎖. There was a significant correlation between plasma vitamin E and supplements (r=0.489, p=0.0001) ; plasma vitamin E was slightly correlated with age(r=0.216, p=0.0017).

The principal objective of this study was to assess the effects of soy isoflavone supplementation on bone mineral density in 36 female college students with osteopenia for 12 weeks. The subjects were divided into three groups on the basis of bone mineral density. The experimental groups were provided supplements of either 80 mg of isoflavone (Iso-80) or 40 mg of isoflavone (Iso-40). To the placebo group, 40 mg of powdered glutinous rice was administered. It was determined that many subjects with osteopenia evidenced lower levels of activity as compared to the control group. Isoflavone supplementation was more effective in controlling total cholesterol and LDL-cholesterol than was observed in the placebo group. We noted no significant differences in serum osteocalcin concentration between Iso-40 and the placebo group, but significant differences in osteocalcin concentration were detected between Iso-80 and the placebo group. Bone quality indices (BQI) were correlated positively with mineral content, lean body mass, muscular mass, and blood components including albumin, Ca, Mg, ALPase, and osteocalcin. Both Iso-40 and Iso-80 supplementation for 12 weeks significantly increased protein and mineral content in the body. As lower intakes of Ca and folate were noted in the subjects, emphasis should be given to adequate intakes of these nutrients in the subjects. In conclusion, 12 week isoflavone supplementation in young females with osteopenia exerted positive effects on bone mineral density and bone turnover markers.

광주시내 영유아를 대상으로 수유와 이유실태조사를 1993년 4월 부터 5월까지 실시했다. 영유아의 이유이전의 수유법은 모유영양이 35.6%, 인공영양이 35.1%, 혼합영양은 29.2%이었으며 초유수유는 68.3%이었다. 아기의 성별, 출생순위, 출생시 체중, 어머니의 교육수준은 어머니의 수유방법에 영향을 주지 않았으나 가정수입은 수유방법에 유의적인 영향을 미쳤다. 영유아들의 이유 시작시기는 4.83개월이었으며, 46.4% 어머니가 과일 과즙은 처음 먹인 이유식이었고, 아이들도 대부분 좋아했으나 채소는 별로 좋아하지 않았다. 어머니들은 곡류를 아이들에게 가장 많은 빈도로 이유식으로 주었으며 52.8%가 시판 이유식을 매일 사용한 반면 33.2%는 전혀 사용을 안했다. 어머니들이 이유식에 관해 정보를 얻는 경로는 학력에 따라 매체가 달랐으며 이유식에 대해 가장 관심을 갖는 것은 이유식 만드는 법이었다. The survey on feeding practice in 202 infants in Kwangju area was understaken from April to May, 1993. The incidence of breast feeding was 35.6% of the interviewed mothers while 35.1% of infants were formula fed. Baby's sex, birth order, birth weight and mother's educational level did not affect the infant's feeding method of the respondents, but family's monthly income affect it significantly(p<0.05). Initiating time of weaning in infants was 4.83 month. Fruits and fruit juice, infant's most favorite food were the first food introduced to infants. Cereals were offered frequently as infant foods while animal protein source and vegetables were lesser used. 52.8% of mothers purchased commercially prepared infant food, while 33.2% of them did not use it at all. Depending on mother's educational level, mother got information on weaning with the aid of different educational materials. The respondents were most interested in the way how to prepare weaning food. It might be suggested that development of effective nutrition education technique specific to the different groups of mothers should be focused.

Bioavailability of Selenium

생체내 Se 이용율은 여러가지 내ㆍ외적인 요인에 의해 영향을 받는다. 그 중에서도 Se의 화학적 형태에 따라 생체내 Se 이용율이 변화된다. 식품이나 동물의 먹이에서 천연적으로 발생하는 중요한 형태는 selenomethionine으로 곡류에 있어서 Se의 주요한 부분을 포함한다. 이 selenomethionine은 생화학적인 과정에서 methionine을 대치하는 것으로 알려져 있다. 또한 생체내 Se 이용율을 판정하는 방법으로는 성장반응, 결핍예방, 조직내 Se농도, Se에 의존하는 효소 glutathione peroxidase의 활동, 화학적 평형등이 쓰인다. The bioavailability of selenium(Se) is affected by intrinsic and/or extrinsic factors. Especially, the chemical form of Se may change bioavailability. Selenomethionine, as an important naturally occurring form of Se in foods and feeds can replace methionine in a number of biochemical processes. Bioavailability assays are growth response, prevention of Se deficiency, tissue concentration of Se, Se dependent glutathione peroxidase activity and chemical balance.

The purpose of this study was to investigate the association between daily beverage intake and obesity in young adults. This cross-sectional study was conducted with 256 adults in their 20s and 30s. Obesity was evaluated by anthropometric measurement of body mass index (BMI), waist to hip ratio and waist to height ratio. In addition, the daily intake of milk, caffeinated beverages, sweetened beverages, and alcoholic beverages was investigated using the dietary record and 24-h recall methods. Based on the BMI, men and women were classified into underweight, normal, overweight and obese. Among men, 38.3% were found to be normal, 28.1% were overweight and 31.3% obese. Among women, 11.7% were underweight, 73.4% were normal, and 10.2% were overweight, which was significantly different from men. In women, the BMI of the milk consumers was significantly lower than the non-consumers. Also, the obesity indices of caffeinated beverage consumers were significantly lower than the non-consumers. An analysis of the correlation between beverage intake and the obesity index showed that the intake of caffeinated beverages among women had a significant negative correlation with the obesity index, and intake of alcoholic beverages had a significant positive correlation with waist to height ratio. This study suggests that intake of milk and caffeinated beverage may have a positive effect on obesity, whereas the intake of alcoholic beverages may have a negative effect, especially in young adult women.
