This study was performed using mealtime atmosphere to characterize the food ecology of Korean children residing in different regions of Korea. A total of 705 elementary school students, 347 girls and 358 boys, were divided into three groups according to the areas where they lived, which included Seoul (n = 230), provincial cities (n = 273) and rural areas (n = 202). The subjects were asked to fill out questionnaires which were categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The results showed that the average height (p < 0.01), weight (p < 0.01) and body mass index (BMIs)(p < 0.01) of the rural group were significantly lower than those of the Seoul and provincial city groups. A significantly higher proportion (10.4%) of the rural group was from disfunctional families, including single parent families, than those of the Seoul (1.7%) or provincial city (4.4%) groups. However, a larger number of children from Seoul ate alone, did not enjoy their meals, and hardly talked to each other during breakfast time, compared to those from the provincial city or rural areas. Also, the proportion (33.0%) of ‘good’ in balance of meal was the lowest (33.0%) in Seoul of the three areas (p < 0.01). Most of the children answered that they liked having breakfast and dinner with the whole family. In conclusion, the food ecology of elementary children differed according to the regions in which they resided. Although children from Seoul had higher BMIs, their nutritional intake was not satisfactory, and their undesirable food ecology could be a contributing factor.

The purpose of this study was to investigate the blood lipid levels of insufficiently nourished elementary school students in Gyeonggi area. Subjects were assigned to deficiency or normal group according to the percent of energy RDA intake. Their nutritional status and serum lipid were evaluated based on questionnaire. anthrometric measurements. 24-hr dietary recalls and blood analysis. The mean age of total subjects was 10.8 years and the average height. weight and obesity index of deficiency and normal group was no significant different. At the result of comparison the Korean RDA with mean daily intakes. all nutrients intakes of normal group were approached the Korean RDA's 75 percentile. But vitamin A. vitamin B_(2). niacin. folate. calcium and zinc intakes of deficiency group were lower than the Korean RDA's 75 percentile. The average food intake of deficiency and normal group was no significantly different. Pulse intakes of deficiency group was significantly lower than that of the normal group(p<0.05). but the nuts and seeds intakes of deficiency group was significantly lower than that of the normal group(p<0.05). The HDL-cholesterol level of deficiency group was significantly lower than that of normal group(p<0.001) and atherogenic index(AI) was significantly higher than that of normal group(p<0.01). To summarize the result. vitamin A. vitamin B_(2). niacin. folate. calcium and zinc intakes of deficiency group were lower than the Korean RDA's 75 percentile. Pulse(p<0.05) and nuts and seeds(p<0.05) intakes were significant difference of deficiency and normal group. And deficiency group had lower HDL-cholesterol and higher atherogenic index than those of the normal group. Also it was suggested that the blood lipids might be related to the adequate nutrients intakes approached the Korean RDA's of elementary school students.

Postmenopausal women lose more bone mass than men as a result of estrogen deprivation. The resultant low bone mineral density (BMD) is a major risk factor in the development of osteoporosis. Calcium, phosphorus and magnesium are main components of bone. The purpose of this study is to investigate nutrient intake and serum osteocalcin, Ca, P and Mg and their correlation to bone mineral density in Korean postmenopausal women residing in rural areas. We conducted 24 hour dietary recalls, anthropometric measurements and blood analysis on 60 postmenopausal women. The BMD of the lumbar spine (L2$\rightarrow$L4) and the femoral neck were measured by dual energy X-ray absorptiometry (DEXA). Subjects were assigned to one of three groups:normal (T-score> -1, n=20), osteopenia (-2.5> T-score $\leq$ -1, n=23), and osteoporosis ( T-score $\leq$ -2.5, n=17). The mean age, height, weight and BMI were 62.37 yr, 154.36 cm, 55.28 kg and 23.18 $kg/m^2$ respectively. The mean daily energy and protein intakes were 76.35% and 87.41% of RDA for Koreans. The mean intakes of calcium, phosphorus, and magnesium were 463.62 mg (66.23% of RDA), 955.32 mg (136.47% of RDA), 345.87 mg respectively. The mean serum levels of calcium, phosphorus and magnesium were 8.76 mg/dl, 3.80 mg/dl, and 2.10 mg/dl, respectively, and there were no significant differences among the three groups. However, the BMD of the femoral neck showed a significantly negative correlation with serum magnesium (p<0.05). To summarize the results, most nutrient intakes (especially calcium) in postmenopausal women did not reach the RDA values for Koreans. Also, increase of serum magnesium levels may be related to bone loss.

The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.

폐경후 여성의 비만도에 따른 영양상태와 항산화능에 관한 연구

승정자,김은영 대한비만학회 2003 The Korean journal of obesity Vol.12 No.3

연구배경: 여성은 폐경을 맞이하면서 호르몬의 변화 등으로 인해 비만 발생률이 높아지며, 그로 인해 만성퇴행성 질환 발병 위험을 초래한다. 이에 폐경 후 비만 여성에서 혈중 항산화효소 활성 및 혈중 지질양상을 비교하고자 하였다. 방법: 폐경 후 여성 60명을 대상으로 2001 국민건강 영양조사의 체질량지수 85th percentile 이상인 대상자를 비만군(27명), 그 이하는 대조군(33명)으로 분류하였다. 신체계측과 식이섭취조사, 혈액 채취를 실시하였고, 항산화효소인 superoxide dismutase, glutathione peroxidase, total antioxidant 활성을 측정하였다. 결과: 연구 차상자의 평균 연령은 비만군이 65.4세, 대조군이 64.2세로 두 군간에 유의적인 차가 없었고, 비만군의 체중(p<0.001), 체질량지수(p<0.001), 허리-엉덩이 둘레비 (p<0.001), 체지방률(p<0.001)이 대조군에 비하여 유의적으로 높았다. 열량 섭취량은 1일 평균 비만군이 1551.4 kcal(권장량의89.4%), 정상군이 1516.1 kcal (권장량의 85.9%)로 두 군간에 유의적인 차이가 없었고, 영양소 섭취량도 두 군간에 유의적인 차이를 보이지 않았다 식품군별 섭취량 조사 결과 비만군의 감자 및 전분류(p<0.01), 난류(p<0.01)의 섭취량이 대조군보다 유의적으로 높았다 비만군의 심혈관계질환의 위험인자와 관련된 지표인 혈청 총 콜레스테롤(p<0.05), 중성지방(p<0.05)의 수준도 비만군이 대조군에 비하여 유의적으로 높았다 항산화효소 활성을 분석한 결과, SOD, GPx, TA 활성은 두 군간에 유의적인 차이가 없었다. 혈액지표간의 상관관차를 분석한 결과 혈중 총 콜레스테롤과 SOD가 양의 상관관계 (p<0.05)를 보였다. 결론: 비만군은 혈청 총 콜레스테롤과 중성지방의 수준이 대조군보다 높아 심혈관계질환의 위험도가증가한 것으로 나타났으며, 차상자의 혈청 총 콜레스테롤은 SOD 활성과 유의적인 양의 상관관계 (p<0.05)를 보임으로써 비만도 증가에 따른 혈중 지질 수준의 변화는 항산화능의 변화와도 관련이 있을 것으로 보여진다. Background: Increases in the number of obese population is an international issue, and Korea is not an exceptional case. In postmenopausal women changes in hormonal profiles may raise a problem of obesity. Obesity is correlated to chronic degenerative diseases and the antioxidant status. The purpose of this study was to compare the antioxidant enzyme activities and serum lipid of obese postmenopausal women to those of non-obese subjects, and investigate the relationship among nutritional status, BMI, and antioxidant enzyme activities in postmenopausal obese women. Methods: In this study, we classified the subjects in to the obese postmenopausal women(n=27) and non-obese (n=33) according to their BMI, and measured dietary intakes, serum lipid, SOD (Superoxide dismutase activity), GPx (Glutathione peroxidase activity) and TA (Total antioxidants capacity). Results: The average age of obese and non-obese were 65.4 yrs and 64.2 yrs, respectively and there was no significant difference. Body weight (p<0.001), body mass index (P<0.00l), waist-hip ratio (p<0.001) of obese were significantly higher than those of non-obese. The mean daily intake of energy in obese and non-obese subjects were 1551.4 kcal (89.4% of RDA) and 1516 kcal(85.9% of RDA), respectively and there was no significant difference. The mean daily nutrient intakes of obese was not significantly from those of non-obese subjects. The obese consumed significantly greater quantities of potatoes (P<0.0l) and eggs (P<0.01) compared those consumed by non-obese. Serum total cholesterol (p<0.05), triglyceride (P<0.05) of obese were significantly higher than those of non-obese. There was no significant difference in SOD, GPx, TA activities. A significantly positive relationship was present between total cholesterol and SOD (p<0.05). Conclusion: Obese postmenopausal women had higher serum total cholesterol and triglyceride than those of the non-obese. Obesity is associated with elevated antioxidant enzyme activities. And that perdisposes the cardivovascular disease to oxidative stress.
