This investigation studied the relationship between Body Mass Index(BMI) and dietary intake, levels of serum lipid, lipoprotein(a) and plasminogen activator inhibitor-1(PAI-1) of 28.449 Korean adults(16.937 men, 11.542 women) from 1995 to 1999. The dietary assessment was conducted using 24-hour dietary records and food frequency questionnaires. During this five year study, the BMI normal-weight group, as a percentage of the annual test population, decreased from 68.0% to 60.2%, while the BMI overweight and obese groups collectively increased from 25.0% to 29.7%. The levels of serum total cholesterol (TC), LDL-cholesterol(LDL-C), Triacylglycerol(TG) and PAI-1 increased as the values of BMI increased, while the levels of HDL-cholesterol(HDL-C) and lipoprotein(a)(men only) appeared to decrease as values of BMI increased. The levels of daily energy intake also increased as values of BMI increased in both men and women. The obese group had significantly higher levels of carbohydrate, protein, fat(men only), and cholesterol intake than those of the normal-weight, underweight, and overweight groups. In men, BMI positively correlated with the levels of macronutrients and cholesterol intake(p＜0.001), % energy of protein, fat, and alcohol intake(p＜0.001), and the levels of serum TC, LDL-C, TG and PAI-1(p＜0.001), while BMI negatively correlated with % energy of carbohydrate intake, and the levels of Lp(a) and HDL-C(p＜0.001). In women, BMI negatively correlated with level of cholesterol(p＜0.01), fat(p＜0.001), alcohol intake(p＜0.05),% energy of fat (p＜0.001), % energy of alcohol intake and level of and HDL-C(p＜0.001). Subjects who had serum TC, LDL-C, HDL-C, and TG levels greater than the standard reference values(TC＞240mg/㎗, LDL-C＞130mg/㎗, HDL-C＞35, TG＞200mg/㎗) exhibited a higher intake of the three macronutrients, iron, calcium, meat, milk and fatty foods than those subjects who had serum lipid concentrations less-than-or-equal-to the standard reference values. Overall, there was positive correlation between the high risk factors of vascular disease variables, dietary intake, and BMI. Prevalence of hypertension and high blood sugar were increased as BMI increased, but the prevalence of hypertension is decreased as the year goes by. These findings showed that dietary intake, level of serum lipids and other vascular disease risk factors increased as BIM increased. Therefore, middle or upper class Korean adults who have high BMI should improve their eating habits. This involve reducing alcohol, animal fat, high carbohydrate foods, and overall food intake, and balancing intake in order to lower vascular disease risk factors, including obesity.

This study was designed to investigate the effect of nutrient intake on bone mineral density (BMD) of the lumbar spine(L2longrightarrowL4) in 41 postmenopausal women. The BMD of the lumbar spine was positively correlated with caiorie protein animal protein fat animal fat calcium animal calcium milk ad dairy calcium phosphorus iron animal iron vitamin A thiamin animal calcium milk and dairy calcium phosphorus iron animal iron vitamin A thiamin riboflavin niacin and ascorbic acid intake. Postmenopausal wmen of BMD$\geq$100% showed enhanced calorie protein fat calcium phosphrous niacin intake compared women of BMD<100% In the group of calorie protein riboflavin intake$\geq$recommended dietary allowances(RDA) BMD was significantly higher than BMD in the group of these nutrient intakes$\geq$700 mg/d is significantly higher than BMD that of examined using stepwise multiple regression analysis. From this analysis in subjects aged 50~59 years fat intake only in subjects aged 60~69 years niacin intake Ca/P in total subjects fat riboflavin intake were signifiant independent predictors of BMD In the group of menopausal significant independent predictor of BMD This study suggests that dietary calcium is a major constituent affecting lumbar spin BMD in postmenopausal women whose menopausal period is over than 5 years.

The purpose of this study was to investigate the correlation of dietary and serum phospholipid fatty acids composition and serum lipid levels in postmenopausal women. Data about anthropometry, dietary intake, physical activities, serum lipid profile and serum phospholipid fatty acid composition were collected from eighty-five postmenopausal women. The subjects were classified as normocholesterolemia (NC), moderate hypercholesterolemia(MC) and phyperchollesterolemia(HC) according to their serum total cholesterol (TC) levels based on The Guideline for Korean Hyperlipidemia set/published by The Committee for Hyperlipidemia in Korea. The results were as follows. Total energy intake and the ratio of energy intake to energy expenditure were positively related, while dietary fiber intake was negatively related, with serum TC level. Dietary fat intake was positively related with serum LDL-C level. Dietary cholesterol, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) intake and the ratio of ingested saturated fat and cholesterol to calories (RISCC) were positively related, while the P/S ratio of dietary fat was negatively related, with serum TC and LDL-C levels. Serum phospholipid fatty acids composition was not significantly different among the three groups. SFA of serum phospholipid fatty acids was positively related, while P/S and M/S ratios of serum phospholipid fatiy acids were negatively correlated, with serum TC and LDL-C levels. We recommend that the dietary P/S ratio of postmenopausal women is increased by reducing their dietary SFA intake. With these changes in the diet, serum phospholipid fatty acid composition could be also changed, and serum lipids levels could be improved.

To investigate effects of ethanol and dietary fat on growth and bichemical indices of liver tissue and blood in rats 40 male rats of Sprague-Dawley wtrain weighing about 160g were divided into 5 groups (low-fat diet group ethanol-administered low-fat diet group high-fat diet group ethanol-administered high-fat diet group and commercial diet group) and fed expe-rimental diets for 8 weeks. Ethanol-administered groups consumed ethanol corresponding to 22 cal% which was considered as moderate drinking. Neither the ethanol intake nor the dietary fat level affected calorie intake. Nonetheless the low-fat diet group with ethanol had the lowest growth rate and 2-fold increase in the concentration of plasma triglyceride. There was no effect of ethanol and dietary fat level on contents of protein lipid and lipid composition of liver tissue. The level of lipid peroxide of liver tissue tended to be increased by ethanol intake but the increase was statistically insignificatnt. The low-fat ethanol group had lowered hepatic mitochondrial respiration rate and deformed structure of mitochondria of hepatocytes.

This research was to examine the correlation between body composition and life style including nutrients intake and physical activities of male and female athletes and nonathletes who are attending college. The percent of body fat with a skinfold caliper was measured higher in female than male. The body fat of the female students in the nonathletic group was the highest and male students in the nonathletic group showed the lowest in body fat. On the correlation between skinfold thickness and body composition the skinfold thick-ness showed negative correlation with the body density. However it showed positive correla-tion with the percent of body fat. According to this result it can be defined that skinfold thickness is in proportion to the body fat. dietary intakes of male and female athletes exceeded the need for their excessive physical activity. Concerning the correlation between calorie intake and body fat was high. From this we conclude that the more one consumes calorie intake the higher one's body fat content will be. On the correlation of physical activity and body composition the lean body mass showed high positive correlation with physical activity.

Since it has generally been considered that high-hat diets promote carcinogenesis, fat intake of less than 30% of total calories has been recommended to reduce the risk of cancer. Specific dietary guidelines for fat intake to reduce the risk of colon cancer have not yet been established. In order to determine the level of dietary fat needed the risk of colon cancer, rats were fed one of four experimental fat diets, very low(7% of total calories from corn oil, VLC), low(15% LC), medium (30%, MC), and high fat(45%, HC). Cell proliferation as an intermediate biomarker of color carcinogenesis was measured by the in vivo incorporation of bromodeoxyuridine into DNA. Fecal lipid excretion was measured by gravimetric method. As fat levels in the diet increased, fecal lipid concentrations also increased (VLC

This study was performed to study the effects of dietary factors on breast and cervical cancer incidence in female Koreans. The subjects were 60 breast and 109 cervical cancer patients recruited from five general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records, from August 1991 to September 1992. Body weight, body mass index, triceps skinfold thickness and body muscle mass were at upper limit of normal value, which suggest that these patients had a tendency of overweight. The levels of hemoglobin and hematocrit of the patients were below the normal values. The values of serum protein, albumin, and calcium were in the normal range but close to the lower bound. Therefore the nutritional status assessed by blood composition seems to be marginal. The results of diet history showed that most of the nutrient intake of the subjects met with RDA. The fat intake were 22.9-36.9g/day which supplies about 15-16% of total calories. The results of this study do not agree with those reports of western societies which showed the positive correlation between calorie and fat intake and the incidence of breast and cervical cancer. Even through the calories and fat intake of the subjects were not high, it was higher than national average, especially in breast cancer patients. From this study, dietary factors does not seem to be a major risk factor in cancer incidence in Korea. However, the tendency of the increasing consumption of fat could be a contributing risk factor together with overweight.

This study investigated the correlations among nutrient intakes and biochemical status in Anyang obese children. The average age of the subjects was 11.34${\pm}$1.36yrs. The average BMI was 25.78kg/㎡ in boys and 25.09kg/㎡ in girls. The average percentage of body fat was 25.62 %. Percentages of subjects at dyslipidemia based on corresponding criteria of total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, atherogenic index were 24.05%, 27.85%, 13.92%, 18.99%, 58.23%, respectively, There were significant difference in dietary fat, vitamin A and niacin in subjects by sex. There were no significant difference in energy, carbohydrates, protein, fat, iron, vitamin A, vitamin B$_1$with respect to BMI, but calcium intakes were found significantly correlated with BMI(p<0.05).The percentage of body fat was also positively correlated with animal fat intake, animal calcium intake, diastolic blood pressure and negatively correlated with HDL-cholesterol, atherogenic index, LHR, plant calcium intake, Based upon this study, the children nutritional education is required for better growth and health promotion of primary school children.

Carcass analysis of most economical parts of broilers were studied after they were fed with different protein levels of 16, 18, 20 and 23% for the starter period and 16, 18 and 20% for the grower period. The energy value of the feed was constant at 3,200 kcal ME/kg. The results for the starter and grower broilers showed similar pattern of responses. There were significant increased in weight gain, feed intake, protein intake, while there were significant decrease in the feed conversion ratio (FCR), abdominal fat and carcass fat when dietary protein increased. For the economical parts of the carcass, most of the fats were found in the thigh meat, while the lowest was found in the breast meat. The protein levels did not influence the meat production of the breast, drumstick and thigh portion. Increasing the protein intake, increased the broiler performance in relation to increased protein content of the breast, drumstick and thigh meat. The different fat contents of the meat might be due to differences in the rate of lipogenesis and fat deposition of the meat.

Recently, osteosarcopenic obesity (OSO) has been identified and notified world wide. Therefore, this study reviewed OSO related to lifestyle factors such as nutritional intake and exercise. Due to aging, OSO may be initiated by dietary factors and obesity related factors. Reduced muscle mass and increased fat mass may negatively impact bone health causing OSO. The complication of OSO development should be related to dietary imbalance combined with declined exercise and this may contribute to induce OSO by decreasing bone mass, muscle mass, and increasing obesity with aging. To prevent OSO, reaching peak bone mass and building optimal muscle and fat mass through exercise would be recommended. For treating OSO, balanced dietary intake and regular exercise through a whole life would be needed. In addition, sufficient carbohydrate and fat intake for minimizing protein catabolism would be recommended to prevent OSO. The combination of aerobic exercise and resistance training also would be an effective intervention for OSO population.
