The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and 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 body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)
This study was conducted to investigate the effects of smoking on nutrient intake and blood mineral status. The subjects were composed of two groups.55 smokers and 52 non-smokers. A 24-hour recall method was used along with questionnaires and serum mineral levels were analyzed by ICP spectrometer. The average ages of the smokers and non-smokers were 55.5 and 59.3 years old, respectively. The height, obesity degree, BMI, and WHR of the smokers were significantly higher than those of the non-smokers (p < 0.05, p < 0.05, p < 0.05, p < 0.01) Approximately 45.5% of the smokers smoked 16-20 cigarettes per day. The average age that the smokers started smoking was 22.0 years old and their smoking history was 33.5 years. About 74.5% of the smokers drank alcoholic beverages, while 44.2% of the non-smokers did. The smokers tended to eat less meals and breakfast meal, but drink coffee more often compared to the non-smokers. The mean daily energy intake and CPF energy intake ratio were 1231.8 ㎉ and 69.8 : 14.8 : 14.7 in the smokers and 1210.2 ㎉ and 72.1 : 14.7 12.7 in the non-smokers, respectively. The results show that the smokers tended to consume more energy, lipid, and cholesterol compared to the non-smokers. The results also show that in both groups, nutrient intake was lower than the RDA. The two groups were not significantly different in terms of the intake frequency of green-yellow vegetables and fresh fruits. There were no significant differences in serum levels of Ca, P, Mg, Cu, Fe, Mn, and Zn. However, serum Se level of the smokers was significantly higher than that of the non-smokers. In conclusion, the subjects of this study showed a serious imbalance in the nutrient intake, and the smokers showed a more undesirable dietary intake in the light of their high intake of energy, lipid, cholesterol, alcoholic beverages, and coffee. The serum Se level of the smokers was higher than that of the non-smokers, showing that Se is involved in smoking, Therefore, it could be suggested that more systematic research be conducted with respect to Se and smoking and that increased nutrition education and guidelines for smokers are required.
This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of healthy weights at community level. Nutrient intakes of 128 housewives were assessed by 24 hour recall method. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Subjects were divided to under-weight, normal-weight, over-weight groups by body mass index (BMI). Most under-weight groups evaluated as their current body images were normal. $41\%$ of normal-weight groups judged as their current body images were obese. Energy and fat intakes of over-weight group were significantly higher than that of under-weight and normal weight groups (p<0.05). However, carbohydrate and protein intakes showed no significant differences among the three groups. It appeared that active attitude toward change in nutrition attitude of normal weight group was significantly higher than that of under-weight group (p<0.05). There were no significant differences of food habit score, nutrition knowledge, and obesity habit scores among the three groups. The frequency of eating-out showed significant difference among three groups (p<0.05). Food habit scores were positively related to health-concerned attitude (r=0.174), convenience-concerned attitude (r=0.229) and food enjoyed attitude (0.213) and negatively related to obesity habit score (r=-0.206). Also, positive correlation of body fat mass with frequency of eatingout (r=0.213), instant food (r=0.227) and amount of meal (r=0.187) existed (p<0.05). We concluded that nutrition education programs for housewives should include specific strategies to modify unsound food behaviors and inappropriate perception of body image for a healthy weight.
The purpose of this study is to investigate diet quality and changes in nutrient and food intake with increase in age. Subjects were 69 patients(28 males, 41 females) living in Jeon-ju city, over middle-aged, and they were the same patients studied 4-7 years ago in a previous study. Dietary survey with one day 24-hour recall method was used. Energy, calcium, vitamin A and vitamin B$_2$intakes were lower than the RDA and vitamin C was in excessive status in pre-test and post-test. In food groups examrned, the consumption of potatoes, beans, vegetables, seaweeds, beverages, seasonings, oils, fish & shells and milks was increased amount than 4-7 years before but the consumption of cereals(p<0.01), sugars, seeds, fruits, processed food, meats and eggs was decreased. Diet quality was assessed by %RDA, nutrient adequacy ratio(NAR), mean adequacy ratio(MAR), dietary diversity score(DDS), meal balance and food group pattern. In %RDA, those proportion of appropriate intake in post-test in were higher than those in pre-test. For most nutrient except vitamin A, the levels of NAR in post-test were higher than in pretest. The MAR, an index of overall dietary quality, was 0.77 for pre-test and 0.83 for post-test(p<0.05). When we counted the major food groups consumed(KDDS), 62.3% of subjects had a KDDS of 3 in pre-test and 42.0% of subjects had a KDDS of 4 in post-test. Based on these results, in terms of variety and balance, total diet quality was improved with advancing of age.
The purpose of this study was to investigate nutrients intakes and nutritional quality of Adults and Elderly People in an island area (Wando). A three-day dietary intakes survey, using a 24 hour recall method was obtained from 187 subjects aged 46 to 84 (mean age 65.3) living in an island area (Wando). Nutient intakes were analyzed using CAN-Pro soft program and compared to Korean RDA. The quality of nutrients was assessed by analyzing nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ). The average daily mean energy intakes were 1869.0 kcal for males and 1943.9 kcal for females, respectively. Daily intakes of protein for males and females were 28.0 and 30.4 g and those of fat were 31.5 and 28.51 g, respectively. Nutrient consumed below $75\%$ of Korean RDA was protein, vitamin A, Ca and Zn in both males and females. Average CPF ratio of males and females were 78.8 : 6.0 : 15.1 and 80.0 : 6.4 13.4, respectively. Energy intake ratio from protein was significantly higher in over 60 years males. Carbohydrate dependency decreased with age. Protein dependency increased with age. Nutrient adequacy ratio (NAR) of energy, protein vitamin A and vitamin E were increased with age in males. The mean adequacy ratio (MAR), an index of overall dietary quality, were not significantly different by age group. Average MAR for males and females was 0.77 and 0.78, respectively. The index of nutritional quality (INQ) showed the tendency to decrease with age. Especially, there were significantly decreases in INQ of all nutrients, except protein, with age. Based on these results, it is evident that people in the island area did not consume enough nutrients. Specially, dietary intake of protein, vitamin A, vitamin E, and Ca were not adequate.

Although dietary intake of pregnant is supposed to have beneficial effects on development of infants, it may be harmful for fetal growth and development since specific food is a common source of toxicants including heavy metal. The purpose of this study was to investigate the association of maternal food intake and mid-pregnancy and their newborns blood lead levels. Pregnant women of 18-20 weeks of gestation were recruited from prenatal clinic in Seoul, Cheonan and Ulsan. In 422 pregnant women, dietary intake during pregnancy was assessed by a 24-hour recall method. Blood sample from pregnant (18-20 wks) and their cord blood at delivery were collected. Blood leas levels were analyzed by atomic-absorption spectrometry methods. Pregnant blood lead levels whose meat and meat products intake were in the highest quartile was significantly higher compared to the lowest quartile. Maternal meat and meat products intake was positively correlated maternal blood lead level (r=0.120, P=0.014). After adjusting for age, maternal blood lead level was positively correlated with their newborn blood lead level (r=0.303, P=0.030). As maternal food intake effects on blood lead levels of pregnant, careful regulation of food intake during pregnancy is perceives to be important in order to bring about desirable pregnancy outcomes.
The objective of this study was to measure anthropometric and haemoglobin level and nutrient intake of expecting women in the third trimester of pregnancy and to relate the birth weight of neonates as outcome of pregnancy. A cross sectional study was performed in Zahedan City. Two hospitals situated in the city were selected based on their approval and cooperation. Five hundred healthy pregnant women in the age group 16-40 years were selected for this study. Findings showed that the mean height, weight, fundal height, and haemoglobin of pregnant women were 156.4 cm, 62.6 kg, 34.2 cm, and 11.1g/dl respectively. Nutrient intake was computed based on 24 hour recall method. The results showed that, the mean intake of energy was 1802 Kcal/day. The intake of protein, calcium, iron, zinc and magnesium were 70.7 g, 544.0 mg, 16.1 mg, 10.6 mg and 266.0 mg respectively. Percentage adequacy of nutrient intakes with reference to RDA recommendation showed 95% and 80% of subjects had sufficient RDA intakes, while energy, calcium, iron and zinc intake considered as insufficient. The mean birth weight of neonates was 3.0 kg and 13% of neonates showed low birth weight. Maternal height, weight, fundal height and haemoglobin level were significantly correlated with birth weight of neonates. Energy, protein and calcium intakes in the third trimester were significantly correlated with birth weight of neonates. Using the binary logistic regression analysis fundal height, haemoglobin level and energy intake of pregnant women were considered as predictor factors of birth weight of neonates.
The aim of this study was to analyse effects that the degree of depression have on the life style variables, nutrient intake, iron indices and pregnancy outcome. Subjects were 114 pregnant women who were receiving prenatal care at a hospital in Seoul. We collected data for general characteristics and lifestyle variables from general survey instrument and for depression score from the questionnaire on depression. Dietary intakes of subjects were estimated by 24 hour dietary recall method. Also we analysed iron indices and pregnancy outcomes. We classified subjects by 10 point, which was the average depression score, into two groups [Low depression score group (LS) : High depression score group (HS)]. As to the intakes of total calcium, plant-calcium, plant-iron, potassium, total folate and dietary folate, LS group was far higher than HS group (P < 0.05, P < 0.05, P < 0.01, P < 0.001, P < 0.05, and P < 0.01, respectively). As to pre-pregnancy alcohol drinking, LS group had 41.9% in non-drinker, which was far higher than 28% in HS group in non-drinker (P < 0.05). As for drinking coffee during pre-pregnancy, pregnant women who don’ drink coffee in LS group took 43.6%, which was higher than 38% in HS group (P < 0.01). Regarding delivery type, the cesarean section in LS group (18%) was significantly lower than that in HS group (45%) (P < 0.01). Bivariate analysis showed that birth weight was significantly associated with the gestational age (P < 0.01). The pregnant women with higher depression score tended to have undesirable life habit, which might affect negative pregnancy outcomes. A better understanding of how depression and intake of nutrients work together to modulate behavior will be benefit nutritional research.

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.
The study aimed to identify major factors related to global self-rated health of the community-dwelling elderly people in rural areas. Interviews were conducted with 433 persons over 65 years of age. The socio-economic characteristics, chronic disease status, measures of functional and mental health, life satisfaction, health-related behaviors including smoking, drinking, exercise, social activity, dietary habit, and food intakes were analyzed to determine their influence on self-rated health index. Data on food intake were obtained through the 24-hour recall method. The self-rated health of rural elderly was poor or very poor as reported by 42.6% and 52.4% of the men and women, respectively. Poor self-rated health was found to be related to elderly aged $65{\sim}74$, female, absence of work, more chronic diseases, dependence on Instrumental Activity Daily Living (IADL), higher mental unhealthy days, lower current life satisfaction, less social activity, lower dietary habit scores, lower intake of total food, fruit, eggs, fishes & shell fishes, vitamin C (%RDA), and Nutrient Adequacy Ratio (NAR). The results of the multiple regression analysis showed that poor self-rated health index is significantly associated with more chronic diseases, mental unhealthy days, gastrointestinal disease, musculoskeletal disease, less social activity, and lower intake of fruits. The results also suggested that improving the nutritional status and functional ability, and reducing the burden of chronic diseases are beneficial to the self-rated health index of the elderly.
