  • The aim of this study researchs status of the nutrient intake between male and female students and the nutrient intake by BMI. This study was done to investigate the body composition and nutrient intakes of 340 college students (170 males, 170 females) in Gyeonggi area. Weight, height, BMI, and blood pressure of these college students were measured Nutrient intake was assessed using the 24-hour recall method, and then calculated using the nutritional evaluation program [CAN Pro 2.0 professional (Korean Nutrition Society, 2002)]. Average height and weight were 176$\pm$5.1 cm, 70.60$\pm$l.l kg in male students and 162.2/$\pm$4.5 cm, 54.4$\pm$7.7 kg in female students respectively. Subjects were divided into three groups by BMI: underweight (less than 18.5), normal weight (18.5 to less than 23), and overweight (more than 23). The ratios of male and female subjects among these groups were 5.3% and 17.6% in underweight, 50% and 65.3% in normal weight, and 44.7% and 17.2% in overweight. Systolic and diastolic blood pressures were 124.0$\pm$1.5 mmHg and 76.1$\pm$14.8 mmHg in males and 1l0.l$\pm$12.9 mmHg and 70.l$\pm$10.8 mmHg in females, all in the normal range. Using nutrient values of the 7th Recommended Dietary Allowanes, the nutrient intake was calculated to Korean RDA (%). Nutrients below 75% Korean RDA were Calcium, Vitamin $B_2$, and Folate and nutrients above 100% RDA were Protein, Fe, Phosphorous, and Vitamin $B_6$. BMI showed positive correlations with body fat (%)(p<0.01) and WHR (p<0.01). Nutritional education is desirable for the improvement of dietary behaviors, body composition and nutrient intake of college students.

  • The purpose of the present study was to examine the nutrient intake status of elderly dementia patients. We surveyed the dietary intake of 50 demented elderly patients receiving a regular diet, who were hospitalized in a geriatric hospital in Yongin, Gyeonggi-do. The average age of the subjects was $79.6{\pm}6.5$ for the males and $80.5{\pm}6.3$ for the females. The average heights were $169.5{\pm}6.0\;cm$ (males) and $154.6{\pm}5.2\;cm$ (females), and the average weights were $58.5{\pm}7.4$ (males) and $51.7{\pm}8.9\;kg$ (females). Depending on the type of dementia, the male patients showed significant differences in their intakes of vegetable protein, fiber, total iron, and non-heme iron between the Alzheimer's disease (AD) and the vascular dementia (VD) groups, and the female patients showed significant differences in their intakes of total protein, phosphorus, zinc, and vitamin $B_6$ between the two groups. The male patients showed significant differences in their intakes of animal-source calcium and carotene according to ability to self-feed. According to physical activity, the male patients showed significant differences in vegetable fat and vitamin A intake, and the females showed significant differences in their intakes of total protein, animal protein, fiber, ash, total calcium, vegetable-source calcium, animal-source calcium, phosphorous, total iron, non-heme iron, heme iron, sodium, vitamins $B_1$, $B_2$, $B_6$, niacin, vitamin C, folate, and potassium. We found that the patients consumed excessive protein, but low amounts of calcium, vitamin $B_2$, and folate. Also, the patients' physical activity abilities appeared to affect their nutrient intakes.

  • This study was intended to investigate the risk of metabolic syndrome (MS) in healthy 92 male smokers (mean age: $44.4\;{\pm}\;7.8\;yrs$). We investigated the anthropometric assessment and dietary intake survey for 2 days by 24-recall method, also blood pressure and serum lipids were measured. The average numbers of cigarettes smoking a day were 21.3/d, smoking duration were 21.5 years. The proportion of fat energy was 24.9% and intakes of vitamin B2, folate, calcium, potassum and fiber were lower than KDRI. The body mass index (BMI) and body fat % were 24.8, 23.9% respectively. The systolic ($134.1\;{\pm}\;1.4\;mmHg$) and the diastolic blood ($87.9\;{\pm}\;1.1\;mmHg$) pressure were in borderline hypertension. Among biochemical parameters, TG ($173.6\;{\pm}\;9.4\;mg/dL$) and fasting blood glucose ($109.0\;{\pm}\;2.4\;mg/dL$) levels were out of normal values. The most occurred problem among the risk factors related to MS was the borderline hypertension (63%) in subjects. Regarding the correlations of anthropometric data with biochemical factors, TG was significantly correlated with the BMI, body fat % and waist circumference. Smoking years showed positive correlation with AI. These results suggest that the smoking habit has significant relations with the risk factors of MS. Therefore, quitting is necessary to prevent MS, and nutrition education and dietary management program are required to prevent the degenerative disease.

  • 소아기의 과체중 혹은 비만은 성인기의 만성질환의 onset 위험을 증가시키는 대사이상을 야기하므로 관련된 obesogenic 환경 (나트륨 섭취 등)을 제어할 필요가 있다. 본 연구에서는 소아기의 과도한 소금섭취가 신장의 재흡수 기능을 조절하는 SLC12A3기능장애로 이어져 고혈압 및 비만을 야기하는지를 확인하고자 하였다. 서울 구로구에 소재한 8~9세 초등학생 752명 (남학생: 379명 여학생: 373명)을 대상으로 BMI가 85 percentiles이상을 비만군으로, 이하를 정상군으로 분류하였다. SLC12A3 rs11643718 유전자형은 GG (wild)와 GA + AA로 분류하여 신체계측, 혈액검사, 식이조사 등을 비교분석하였다 대상자의 남아가 여아보다, 비만군이 정상군보다 신체지수, 혈액지수, 식사섭취량이 여아보다 높았다. 남녀 모두 비만군에서 높은 TG와 낮은 HDLc를 보여주었지만 비만한 남아는 혈압에, 비만한 여아는 인슐린저항성에 더 민감한 반응을 보였다. 비록 남녀차이는 있지만 비만군 및 정상군 모두에서 SLC12A3의 GA + AA형이 GG형보다 혈압과 체중이 높았다. GG 유전자형을 가지고 있는 소아는 혈중 LDLc, FBS, insulin등이 높거나 식이 콜레스테롤섭취가 증가할수록 비만이 될 위험도가 증가하였고 엽산의 섭취가 증가할수록 비만위험도는 감소하였다. 반면, GA + AA 유전자형을 가지고 있는 소아는 고나트륨 (> 4,000 mg/day)섭취시 비만위험도 (odd ratio)가 15.57배 증가하였고 남아 (22.84배)에서 더욱 위험도가 높았다. HDLc의 경우는 유전자형에 관계없이 증가할수록 비만위험도가 감소하였다. 결론적으로 SLC12A3 (rs11643718) 유전자의 A allele를 가진 형이 나트륨에 특이적으로 반응하여 과체중위험을 증가시키는 것으로 생각된다.

  • Background: Methyl donor status influences DNA stability and DNA methylation although little is known about effects on DNA methyltransferases. The aim of this study was to determine whether methyl-donor status influences DNA methyltransferase (Dnmt) gene expression in cervical cancer cells, and if so, whether there are associated effects on global DNA methylation. Materials and Methods: The human cervical cancer cell line, C4-II, was grown in complete medium and medium depleted of folate (F-M+) and folate and methionine (F-M-). Growth rate, intracellular folate, intracellular methionine and homocysteine in the extracellular medium were measured to validate the cancer cell model of methyl donor depletion. Dnmt expression was measured by qRT-PCR using relative quantification and global DNA methylation was measured using a flow cytometric method. Results: Intracellular folate and methionine concentrations were significantly reduced after growth in depleted media. Growth rate was also reduced in response to methyl donor depletion. Extracellular homocysteine was raised compared with controls, indicating disturbance to the methyl cycle. Combined folate and methionine depletion led to a significant down-regulation of Dnmt3a and Dnmt3b; this was associated with an 18% reduction in global DNA methylation compared with controls. Effects of folate and methionine depletion on Dnmt3a and 3b expression were reversed by transferring depleted cells to complete medium. Conclusions: Methyl donor status can evidently influence expression of Dnmts in cervical cancer cells, which is associated with DNA global hypomethylation. Effects on Dnmt expression are reversible, suggesting reversible modulating effects of dietary methyl donor intake on gene expression, which may be relevant for cancer progression.

  • This study was investigated nutrient intakes and dietary evaluation index of the healthy subjects over 85 of Sunchang County to explore the improved dietary pattern for healthy aging of the elderly. The survey was conducted by personal interview to 161 elderly subjects (59 males and 102 females over 85) in 2006, and their daily dietary intake was assessed by 24-hr recalls and weighing one meal. The daily energy intakes of males were 1,335 ${\pm}$ 67 kcal, and those of females were 1,095 ${\pm}$ 38 kcal comprised of 66.8% and 68.4% of the EER for the age group of 75. The proportions of energy from carbohydrate : protein : lipid were 70.7 : 14.6 : 14.6 for males and 68.6 : 14.0 : 17.4 for females. The average protein intakes were 95.4% for males and 85.0% for females of RI, and the average calcium intakes were 54.3% for males and 43.6% for females of RI. The daily vitamin intakes were below 70% except vitamin A, vitamin $B_6$, and vitamin E. The proportion of the relative risk groups of protein, phosphate, iron and vitamin A ranged 40-49% of RI over 75 year groups. The other nutrient intakes showed that there were over 50% risk groups. Especially for nutrients such as calcium, vitamin $B_1$, vitamin $B_2$, vitamin C, folate and niacin over 70% of the subjects were under risk. The median value of all nutrient intakes did not reach AI. The INQ of nutrients were over 0.8 except for folate and vitamin C. Calcium intakes were relatively low and needed attention. However, the ratio of calcium and phosphate showed 1 : 1.6, which appeared to be superior to the other districts. The DVS were higher as the dietary balance scores, KDDS were higher, and the groups with high KDDS had high intakes of nutrients compared to the groups with low KDDS. The high risk groups as judged by simple nutrition screening test had lower nutrient intakes than the groups of middle risk or low risk groups. The subjects in Sunchang area had relatively low intakes of several nutrients. However, judging from the desirable patterns of the energy proportion from three major nutrients, ratio of calcium and phosphate and INQ of nutrients there is a possibility that extended healthy aging might be related to the quality of nutrients and relative ratio between nutrients. To improve nutrient status of the elderly of the surveyed area further application involving KDDS and DVS appeared to be required.

  • The assessment of children's nutritional intakes is important because any nutritional inadequacies or toxicities may have adverse consequences. Studies on the nutritional intakes of Korean children are limited. The aims of this study were to determine anthropometric indices, estimate selectee nutrient intakes of young Korean children, and compare these intakes with current Dietary Reference Intakes for Koreans. This study included 136 healthy children(65 boys, 71 girls), 2-6 y old, living in Kwangju, Korea. Weights and heights were measured. Three consecutive 24-h food recalls were obtained. According to International Obesity Taskforce BMI cutoffs, 8% were overweight and 2% were obese. The energy intakes of 40% were < Korean Estimated Energy Requirements, while all subjects consumed $\geq$ Korean Estimated Average Requirement(EAR) for protein. The majority of the children consumed > Korean EAR for iron, zinc, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, and niacin. Vitamin E intakes of 65% of the Korean children were < Korean Adequate Intake, and approximately half of the subjects had < Korean EAR for calcium and for folate. Many young children in Kwangju, Korea, likely have inadequate status of calcium, folate, and vitamin E.

  • 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.
