This study was designed to evaluate health and nutritional status of elderly females according to their family type. The participants were 157 elderly women(41 living alone, 45 living with a spouse, and 71 living with family). Among them, the subjects answered that their health rated as good condition, the elderly living with a spouse had significantly higher proportions than those living alone and living with family. Serum cholesterol and fasting blood glucose of the respondents living with a spouse were lower than those of the respondents living alone or with family. A dietary assessment with a 24-hour recall method represented that the elderly living alone had lower nutrient intakes, especially the intake of Ca. Most of women living alone or with family were consuming less than 75% of the Korean Recommended Dietary Allowances(RDA). For the females living with a spouse, the number or nutrients consumed below 7s% or the Korean RDA were significantly lower than that for those living alone and the elderly living with family. As a result of the above analysis, the health and nutritional statement of old women with a spouse was better than that of the old living alone or with family.

Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based cross-sectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84,95% confidence interval 1.10-3.06) . Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.

This study was designed to investigate the effects of weight reduction and changes in serum lipid composition using a commercial uncooked powdered food (UPF) diet on 27 obese hyperlipidemic women over a period of 12 weeks. We replaced the standard breakfast and dinner of each of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using a body fat analyzer. Also, we conducted hematological, clinical and lipid profile analyses of their blood. Their intake of energy, lipid and protein significantly decreased as the subjects started to take UPF, but their intake of vitamins and minerals, other than iron, increased. Due to the energy intake decrease, the subjects' weight, body fat and waist circumference significantly decreased. Among the lost weight the percentage of the body fat was high. We judged that this process of losing weight was successful in obese hyperlipidemic women. Serum HDL-cholesterol gradually increased and serum total-cholesterol, LDL-cholesterol, triglyceride levels showed gradual decreases. When obese hyperlipidemic women replaced two of three meals with UPF for 3 months, we were able to see useful changes like decreased body fat and serum lipid. Complete judgment on the usefulness of UPF may be difficult but if people take a standard meal once a day and replenish their iron by taking UPF twice a day, we assume that replacing UPF with balanced regular meal not be a problem in nutritional status. Our results show that UPF is effective in the diet therapy of obese hyperlipidemic women.

This study examined 'traditional' and 'modern' food use in Korean adults. Using a 24 hour recall method, trained interviewers assessed dietary intakes of 240 subjects aged 20's to 50's living in Seoul. Depending on the cultural characteristics of foods, 495 different kinds of foods eaten by the subjects were classified into 6 (Korean, Western, Eastern, modified Korean, modofied Western, modified Eeatern) types. The foods were also divided into 3 ('main dish', 'side dish', 'others') categories. Based on these categories, the dietary intakes of the subjects were analyzed in terms of proportionate frequencies of individual food items. The most frequenctly eaten food was the Korean food (67.68%), followed by the Western (22.61%), modified Eatern (2.31%), modified Western (1.65%), and modified Korean (1.36%) foods. Regarding the main dish category, the Korean food received the highest proportion due to the Korean's frequent intake of rice. Korean style foods were the most frequenctly consumed side dish (43.97% of total food consumption). In particular, kimchi consisted of 27.4% of the foods consumed as a side dish. In the 'others' category, Western style foods obtained the highest proportion owing to coffee consumption. The results of the study indicates some methodological problems and suggests a need for further studies.

The purpose of this study was to examine nutrient intakes, food and daily habits, and serum lipids for female college students. The subjects consisted of 70 female college students aged 20 to 29 years old. Their dietary intakes were assessed by means of 24 hour dietary recall method. Food models and other measuring tools were also used. Concentrations of serum lipids were measured. The energy intake of the subjects averaged 1837Kcal, whereas the expended energy was 1871Kcal. The subjects consumed 310g of carbohydrates, 66g protien, 37g lipid, 14mg iron, 586mg calcium, 513R.E. vitamin A, 1.0mg vitamin B1, 1.3mg vitamin B2 1.5mg niacin, and 69mg vitamin C, respectively. Vitamin A and iron intakes were lower than the RDA. The percentages of total calorie from carbohydrate, fat, and protein were 67%, 18%, 14%, showing desirable calorie construction. The mean serum triglyceride(TG), cholesterol (Chol), HDL-Chol and LDC-Chol concentrations were 72.4mg/dl, 161.3mg/dl, 44.5mg/dl, and 102.3mg/dl, respectively. All of these values seem to fall in the desirable range. There were positive correlations between serum Chol and HDL-Chol or LDL-Chol or TG ; negative correlations between serum Chol and HDL-Chol/LDL-Chol ratio, between serum TG and HDL-Chol or HDL-Chol/LDC-Chol ratio.

The purpose of this study was to examine the relationship between sugar intake and behavioral problems in Korean school children. The subjects were 280 school children lived in Soung Nam city. Nutrient and sugar intakes were measured by 24-hour recall method and food frequency method through personal interview. Hyperactivity scores of children were measured by teacher and mother using conners Rating Scale-Revised. The average daily total sugar intake for the total sample was 63.0$\pm$37.4g(Range : 10g-220g). The result of stepwise multiple regression analysis using the sugar intake as dependent variable showed that energy, participation of school lunch program, Vit B2, protein, education of fathers, niacin, calcium are significant explanatory variables, explaining 44.8% of variation. As a result of the Conners scale test by teacher, 4% of children were Attention Deficit Hyperactivity Disorder(ADHD) children. A result of the Conners scale test by mother, 8% of children were ADHD children. The result of simple regression analysis had not shown significant relationship between sugar intake and ADHD scores. But the result of the Conners test by teacher, sugar intake(69.9$\pm$37.1g) of ADHD children were significantly higher than sugar intake(62.9$\pm$37.7g) of normal children(p<0.01).

As ciarette smoking adversely affects vitamin C metabolism in humans, smokers need substantially more vitamin C intake than do non-smokers to achieve similar serum vitamin C concentration. To provide the basic information currently available for the determination of vitamin C requirement for Korean smokers, we investigated the differences the serum vitamin C values between smokers(n=53) and non-smokers(n=62) in relation to their intake of the vitamin through diet in 115 male college students, who had not been using vitamin C supplements. Dietary intakes of vitamin C were determined by a 24-hour recall, and serum vitamin C was determined using the 2, 4-dinitrophenylhydrazine method. The mean vitamin C intakes of smokers and non-smokers were consuming less than 75% of the Koeran RDA for vitamin c in their diet. Smokers consumed yellow and green leafy vegetables more often (P=0.02) and fresh fruits less often(P=0.006) than non-smokers. The mean serum vitamin C concentration of smokers consuming the same amounts of vitamine C as non-smokers, 64.3 umol/1, were 20% lower than for non-smokers, 80.1 umol/l(P<0.05). The risk of low serum vitamin C concentration (LoC) among smokers were 3.8% compared with 1.6% in non-smokers, and the odd ratio for LoC risk was 2.43. There were no correlations between dietary and serum vitamin C for smokers and non-smokers. It was concluded that smokers might require at least 20% more vitamin C to reach the same concentration comparable to non-smokers.

Bacterial transformation of bile acids is possibly involved in colorectal carcinogenesis. n several epidemiological studies, the fecal bile acid dietary fiber are related to the indicence of colonic cancer. This study investigated the influence of age, dietary fiber intake on fecal bile acid profiles in healthy subject. The dietary fiber were assessed by mean of 24 hour dietary recall method, the subjects consist of 238 members aged 20 to 64 years old and feces are collected from the subjects. Fecal bile acids and neutral sterols were analyzed by gas chromatography. Mean dily crude fiber intake level was 7.7$\pm$1.4g(dietary fiber : 16.7$\pm$3.5g), dietary fiber intake range being 6.5-36.8g. The dietary fiber intake in elederly subject was significantly lower than in the other younger groups. Dietary fiber intakes was negatively correlated with the total bil acid concentation in feces. Probably, a decrease in dietary fiber intake results in higher fecal bile acid concentrations. The secondary bile acid concentration is related to the colon cancer, deoxycholic acid and lithocholic acid were significantly higher in elderly subjects. Concentration of fecal total bile acid, deoxycholic acid, coprostanol, coprostanone were higher in low dietary fiber intake group. These results suggest that the risk factor for colon cancer might be reduced, when dietary fibers are consummed more.

This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

This study was carried out to see dietary intakes of patients with coronary heart disease since we don't understand their dietary patterns even though the mortality and prevalence rate of coronary hear disease are increasing in this country. We studied 75 coronary heart disease patients and 150 randomly selected controls, matched for age, sex, height and weight, in a population based study. All subjects completed a questionnaire that included disease history, diagnosis time, current treatment, etc., a 24 hour dietary recall, and measurement of height and weight. Compared to controls, patients had less likely to drink alcohol and smoke cigarette (p＜0.05). The energy intake of patients was significantly lower than that of controls, but the intakes of fiber, $\beta$-carotene, sodium, folate, vitamin C, potassium in male patients and those of vitamin C and sodium in female patients were significantly higher than those of controls (p＜0.05). Mean adequacy ratio and dietary variety score of patients were also higher than those of controls (p＜0.05). Patient group's consumed less cereals than controls, but more vegetables, milk products, and nuts in male patients and fruits, beans and seasonings in female patients compared to controls'. There were not significant differences of lipid compositions between two groups, except linolenic acid. These data suggest that patients with coronary heart disease in Korea had better dietary nutrient intakes compared to healthy controls, which might be helpful to prevent recurrence of coronary heart disease.
