This study was performed to investigate socioeconomic factors relating to obesity and inadequate nutrient intake in women in low income families residing in Seoul. The subjects were 125 women (aged 41-87 y) recruited from the local health center for free health examination for low income families. The socioeconomic status such as educational level, income level, and housing condition were poor. For subjects aged less than 65 years, the prevalence of obesity was 44% based on BMI (${\geq}\;25\;kg/m^2$), 48% based on WHR (${\geq}\;0.85$), and 50% based on waist circumference (${\geq}\;80\;cm$) and for those more than 65 years, these were greater and 57%, 81%, and 79%, respectively. The main food sources of daily diet were vegetables, grains, and fruits. Energy and other nutrient intake was not adequate for all subjects and the inadequacy was more profound in the elderly, showing percentages of subjects whose intake was less than EAR were greater than 50% for all nutrients except for iron and below RI were also greater than 50% for all nutrients. The prevalence of obesity and nutrient inadequacy were not associated with socioeconomic status in subjects aged less than 65 years, however, obesity was associated with household income and nutrient inadequacy was related to education (vitamin A) and housing status (protein, phosphate, and iron) in the elderly. After adjustment for ages, in the elderly, OR for obesity (BMI ${\geq}$ 25, OR = 12.601; 95% CI = 2.338-67.911) and central obesity (WC ${\geq}$ 80 cm, OR = 4.778; 95% CI = 1.103-20.696) were greater in subjects who earned less than 500 thousand Won per month than who earned more. For inadequate nutrient intake, the OR for inadequate intake of Vitamin A (OR = 4.555; 95% CI = 1.491-13.914) was greater in subjects with no education than those educated. Subjects without her own house had greater risk for inadequate intake for protein (OR = 3.660; 95% CI = 1.118-11.981), phosphate (OR = 3.428; 95% CI = 1.157-10.158), and iron (OR = 3.765; 95% CI = 1.205-11.766) than subjects possessing her house. In elderly females in low income families, the socioeconomic status was associated with the risk for obesity (income level) and inadequate nutrient intake (education level and housing status). More attention on these groups should be given for prevention of obesity and inadequate nutrient intake.

The purpose of this study was to investigate the relationship between alcohol consumption and nutritional status of university male freshman in Chungnam area. The total of 111 subjects took part in the study and, they were observed general characteristics, alcohol consumption status, and nutrient intake using questionnaires. The mean age, height, weight, and BMI of the subjects were 19.3 years, 174.3㎝, 65.2㎏, and 21.5㎏/$m^2$ respectively. The mean alcohol consumption, and energy intake from alcohol were 7.8g/day, 55.3kcal/day. A significant number of subjects(48.2%) answered their frequency of alcohol consumption was once 2 weeks. Only 4.6% of subjects answered never drink. In almost subjects, alcohol consumption have been stared since they were adolescents, and major type of alcoholic beverage was 'soju'. The mean energy intake was 1985.6kcal and, energy ratio from carbohydrate, protein, fat was 58 : 15 : 27. There were significantly positive correlation among alcohol consumption and, body weight(p<0.05), intake of food, (p<0.05), energy(p<0.001), animal fat(p<0.05), fiber(p<0.05), vitamin $B_2$(p<0.05) and niacin(p<0.05). The alcohol consumption period showed a significantly positive correlation with alcohol consumption per one time(p<0.05). In summary, high consumption of alcohol in subjects was observed. Also, increase of alcohol consumption was related to weight gain and nutritional imbalance. Therefore, it is need that nutrition education for prevention of high alcohol consumption in university freshman and adolescents.

This is an analysis of the dietary behavior, nutrient intake status and INQ(Index of nutritional quality) of 129 college women according to their residences in the Daegu area. The average height and weight were 160.0 cm and 54.5 kg respectively. Diet intake data were obtained by using the 24-hour recall method to evaluate the usual diet of the subjects. The energy intake of the group, living alone was higher than that of living a roommate and living at home. Ca, Fe, Zn and folate intakes were low in all the groups. The composition rate of carbohydrate, protein and fat for energy intake was 58.9 : 15.5 : 25.6 in living alone, 59.9 : 15.1 : 25.0 in living with a roommate and 61.2 : 15.5 : 23.3 in living at home, compared with the preferred of 65 : 15 : 20. The group living alone showed significantly better mean adequacy ratio(MAR, 0.7) than the other groups (p<0.05). The group living with a roommate showed significantly better INQ in vitamin $B_6$ (p<0.01) and Fe (p<0.05) than the other groups did In conclusion, this study indicates that nutrient intake in college women in Daegu is considerably lower than the RDA values. Furthermore the group living alone showed better dietary behavior and nutrient intake status than the other groups. A nutrition education program for college women is necessary.

The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.

This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (<36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4mg/dl, 69.9mg/dl and 67.4mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200mg/dl) and LDL-cholesterol (＞130mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However. there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.

The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.

This study was aimed to investigate the nutriational status of Korean female college students who are attending school at a longdistance. Physique calssification by anthropomethic indexes, Body mass index(BMI) & Brocas' index and the body fat distrubition were investigated. The energy balance was also examined comparing caloric intake with caloric expenditure. The result of this study are followings; (1) Average height and weight were 158±17.8 cm, 51.7±7.8 kg. This results were not quite different from '84 Korean Adult Standard of 159.5cm, 52.5kg. (2) By Broca's index, 25.89% of subjects was underweight 67.0% was normal weight and 7.06 was overweight. By BMI, 40% of subjects was underweight, 58.8% was normal weight and 1.2% was overweight. (3) According to % fat measured. By BIA, 7% in subjects was underweight, 64.2% was normal weight, 22% was overweight and 6.1% was obesity. This result differed from BMI's result. It may be measurement error due to the difficulty of removing metal sticking to underwear and tooth correction. (4) The intakes of the nutrients except protein, P, vitamin B₁ complexes, were lower than the intakes indicated by Korean Recommended Allowances. 95) Average caloric intake a day was 1545±394.4 kcal, which was much lower than the RDA. The caloric expenditure was much more than caloric intake, which showed negative energy balance in the subjects of this study.

This study was designed to investigate the obesity rate with anthropometric indices, nutritional status and serum lipid levels of 260 school children from 5th grade of elementry school residing in Puchon city. Obesity was defined as fat percentage that exceeds 25$\%$. The prevalence rate of obesity were 15.2$\%$ for male and 14.1$\%$ for female. Mean fat percentage, BMI and Rohrer indice of obese male were 30.3$\%$, 21.0 and 150.2 respectively and 28.0$\%$, 21.5 and 151.9 for obese female. Mean serum TG, apo-B of obese female was significantly lower than that of non-obese. Obese male did not show any difference in serum lipid levels. The proportion of students whose serum cholesterol levels exceed 170mg/dI, which is cutoff point of bordeline for coronary artery disease, was 12.0% for male and 15.6$\%$ for female. The major factors affecting nutritional status were the amount of living expense, existence of mother's job and the regularity of having breakfast. Children who's living expense more than 500 thousants Won showed lower intake of Iron, vitamin A, thiamin, niacin and ascorbic acid(p$\ll$0.05). Children who's mothers are having a job were observed with decreased height(p$\ll$0.05). Children having breakfast regularly showed increased BMI and Rohrer indice than those of children having breakfast often of never.

This study was performed to evaluate the effectiveness of food commodity supplementary program for low-income, living alone elderly people. The subjects were 57 low income aged females who lived alone in Bucheon city. The food commodity supplementary program lasted for 6 months, supplying one meal per day consisting with grains, meat, vegetables, dairy and fruit. Dietary intake, anthropometric measurements, and blood profiles were assessed. After 6 months of food commodity supplemented period, dietary intakes of protein(p<0.05), calcium(p<0.05), iron(p<0.05) and vitamin B(p<0.001) were significantly increased. The mean weight(p<0.05) and BMI(p<0.05) were increased, and the frequency of BMI over 25kg/m$^2$ was also raised from 54.4% to 59.7%. Serum concentrations of total protein(p<0.001) and albumin(p<0.001) were significantly increased, indicating improvement of protein status. The frequency of anemia was decreased from 45.6% to 26.3%. However, the proportion of dyslipidemia was increased. In general the stable food commodity supplementary program was effective to improve general nutritional status of the poor aged who lived alone, however, nutrient intakes still did not meet RDA for the elderly and the rates of obesity and dyslipidemia were increased. Therefore, local government should provide more active food support program and the selection of food items for commodity should be evaluated at regular intervals.
