The purpose of this study was to examine the correlation between nutrient intakes and bone mineral density in female university students. A total 27 female university students were measured the anthropometric characteristics, dietary intake and the bone mineral density of carpus using DEXA. The average age, height, weight, % body fat, WHR, and BMI of the subjects were 22.7 years, 161.5 cm, 57.0 kg, 29.9%, 0.8, 21.8 kg/$m^2$, respectively. Bone mineral density of ultradis and distal carpus as T-value were -1.5 and -0.4, respectively. The daily energy intake of the subjects was 1589.0kcal. And the intakes of energy, calcium, iron, zinc, vitamin $B_2$, and folic acid did not meet the Korean RDAs. The daily total food intake of the subjects was 1011.0g and food intake from cereals and vegetables was high. The major food groups of mineral intake were vegetables/cereals/milks/fishes for calcium, cereals/meat/vegetables/fishes for phosphorus, cereals/vegetables/meats for iron, seasonings/vegetables/cereals for sodium, vegetables/cereals/seasonings for potassium, and cereals/meats for zinc. The body weight and body mass index were significantly positive correlated to the bone mineral density of average carpus, respectively. The intakes of animal calcium and vitamin $B_2$ were significantly negative correlated to the bone mineral density of average carpus, respectively. In conclusion, bone mineral density in carpus and nutrient intakes of some female university students were low. Therefore, health management and the study on relation between bone mineral density in various site and long-term intakes of nutrients in many subjects are required.

Materials for nutrition education to promote nutrition intake and prevent diseases in elderly individuals were developed, nutrition education was provided to 46 elderly females for 12 weeks, and its effects on the body composition, blood profile, and nutritional quality of subjects were qualitatively analyzed. After the education program, the weight of subjects decreased from 56.7 kg to 56.0 kg (p<0.001), their body fat dropped from 20.8 kg to 19.6 kg (p<0.01), their body mass index (BMI) declined from $25.2kg/m^2$ to $24.9kg/m^2$ (p<0.01), and their percentage of body fat decreased significantly (p<0.05). On the other hand, blood sugar showed a significant increase from 131.6 mg/dl to 141.8 mg/dl (p<0.05). Overall, the percentage of nutrition intake rose. In particular, the estimated energy requirement increased from 89.3% to 99.5% (p<0.05). Further, the contrast ratio of recommended intake showed significant increases in protein (p<0.01), phosphorus (p<0.05), vitamin $B_2$ (p<0.05), vitamin $B_6$ (p<0.05), and niacin(p<0.001), and that of adequate intake showed a significant increase in sodium (p<0.05). The nutrient adequacy ratio (NAR) showed a significant increase only in niacin (p<0.05), and the index of nutritional quality (INQ) showed significant increases in protein (p<0.05) and niacin (p<0.001). After the nutrition education program, a qualitative analysis of nutrients consumed by subjects was conducted. The results show improvements across the board except for the deficient intake of calcium and folic acid, suggesting that the nutrition status of subjects changed in a positive direction through the program. The implementation of this program for elderly individuals in a continuous and repetitive manner is expected to facilitate their nutrition management.

The purpose of this study was to compare nutrient intakes and blood lipids according to the obesity index of middle aged men. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat),; normal weight (10-20% fat), overweight (20-25% fat) and obesity (over 25% fat). Nutrient intakes were evaluated based on questionnaires and 24 hour recall method and blood lipids were analyzed by blood analyzer. The results were as follows: 1) Nutrient intakes were that carbohydrate intake rate in obesity group was lower than normal group and lipids intake rate in obesity group was higher than normal group. The intake of riboflavin and folic acid were differ normal and obesity group (p < 0.05), and normal group ingested under recommended intake. 2) Total-cholesterol, LDL-cholesterol and blood pressure in obesity group were higher than normal group but the differences were not significant. The attack rate of coronary heart disease and blood glucose in obesity group is higher than normal group (p < 0.05). 3) The correlation of anthropometric measurements, blood lipid, blood glucose and blood pressure had significant results. Soft lean mass was associated BMI (p < 0.01), TC (p < 0.05), HDL (p < 0.05), LDL (p < 0.05) and SBP (p < 0.05). TG was associated TC (p < 0.05), HDL (p < 0.01), VLDL (p < 0.001) and Risk (p < 0.01). TC was associated LDL (p < 0.01) and Risk (p < 0.01). Blood glucose was associated TC (p < 0.05), LDL (p < 0.05), SBP (p < 0.05) and DBP (p < 0.05). These results suggest that reduction of body weight for the attack risk of obesity group in coronary heart disease.

Objectives: Prolactin is vital for breastfeeding and milk production, and its secretion is influenced by factors related to the mother, infant, and environment. To date, no study has concurrently investigated the correlation of these factors with serum prolactin levels during lactation. Therefore, the objective of this study was to investigate the correlations among maternal and infant factors, lead exposure, and serum prolactin levels during lactation. Methods: A cross-sectional approach was employed in Surabaya, Indonesia, among 110 exclusively lactating mothers. The mothers' daily diets were determined using multiple 24-hour recalls, while blood lead levels were measured with inductively coupled plasma mass spectrometry. Serum prolactin levels were assessed using the electrochemiluminescence immunoassay. For bivariate analysis, we employed the Spearman correlation, Mann-Whitney, and Kruskal-Wallis tests, while for multivariate analysis, we utilized multiple linear regression. Results: The average serum prolactin level of the lactating mothers was 129.19±88.96 ng/mL. Positive correlations were found between serum prolactin levels and breastfeeding frequency (p<0.001), protein intake (p<0.001), and calcium intake (p=0.011) but had negative correlation with blood lead levels (p<0.001) and vitamin B6 intake (p=0.003). Additionally, prolactin levels were not significantly associated with maternal age; parity; intake of calories, vitamin D, vitamin E, zinc, folic acid, magnesium, or iron; infant age; or infant sex. Conclusions: Breastfeeding frequency had a stronger positive relationship with serum prolactin levels than protein and calcium intake. However, lead exposure was associated with reduced serum prolactin levels during lactation. Consequently, specific interventions from policymakers are necessary to manage breastfeeding in mothers exposed to lead.

Objective: Adequate vitamin and trace mineral intake for pigs are important to achieve satisfactory growth performance. There are no data available on the vitamin and trace mineral intake across pig producers in China. The purpose of this study was to investigate and describe the amount of vitamin and trace minerals used in Chinese pig diets. Methods: A 1-year survey of supplemented vitamin and trace minerals in pig diets was organized in China. A total of 69 producers were invited for the survey, which represents approximately 90% of the pig herd in China. Data were compiled by bodyweight stages to determine descriptive statistics. Nutrients were evaluated for vitamin A, vitamin D, vitamin E, vitamin K, thiamine, riboflavin, vitamin B₆, vitamin B₁₂, pantothenic acid, niacin, folic acid, biotin, choline, copper, iron, manganese, zinc, selenium, and iodine. Data were statistically analyzed by functions in Excel. Results: The results indicated variation for supplemented vitamin (vitamin A, vitamin D, vitamin E, vitamin K, vitamin B₁₂, pantothenic acid, niacin, and choline) and trace minerals (copper, manganese, zinc, and iodine) in pig diets, but most vitamins and trace minerals were included at concentrations far above the total dietary requirement estimates reported by the National Research Council and the China's Feeding Standard of Swine. Conclusion: The levels of vitamin and trace mineral used in China's pig industry vary widely. Adding a high concentration for vitamin and trace mineral appears to be common practice in pig diets. This investigation provides a reference for supplementation rates of the vitamins and trace minerals in the China's pig industry.

The objective of this study was to investigate the nutritional and health status of women industrial workers by working fields. One hundred forty eight (105 lead and 43 office) workers were recruited from March 2005 to October 2005. Information on age, education, smoking and drinking status were collected using questionnaire and nutrient intake and diet quality of workers were assessed by average of two-day 24 hr recall method. Biochemical indexes including blood lead level (PbB), indexes for iron status, serum calcium (Ca) and serum lipid profiles were analyzed from fasting venous blood or serum. Results showed that education level of lead workers was lower than that of office workers (p<0.05), but nutrient intake levels were not significantly different by working fields. Overall nutritional status of the subject were good except for calcium, vitamin $B_2$, C and folic acid intakes. PbB of lead workers were significantly higher than that of office workers while mean corpuscular hemoglobin concentration (MCHC) and serum Ca levels were significantly lower in lead workers. MCHC was positively correlated with zinc intake (r=0.166) and serum Ca was positively correlated with vitamin C intake (r=0.179). This study confirms that lead workers need extra care to keep their health and nutritional management especially for the nutrients known to interact with lead. Tailored nutrition education for workers at specific working fields needs to be more focused for the improvement of health status of industrial workers.

Korea's aging population has been remarkably increased. They want to have not only extension of life expectancy but also improving quality of life. To maintain the quality of life, it is essential to have good nutrition. However, nutritional status of elderly in Korea has problems qualitatively and quantitatively. Risk factors for poor nutrition are advanced age, woman, living alone and low economic status. Another risk factor in rural area is season because seasonal changes can affect food intake of elderly. Thus this study surveyed the health status and dietary intakes of elderly by season in rural area. In this study, the elderly were grouped as group 1 {elderly who have one risk factor for chronic diseases (obesity, hypertension, dyslipidemia, diabetes)} and group 2 (elderly who have more than 2 risk factors). Can-Pro 3.0 was used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. Obesity had the highest percentage 62%, followed by hypertension 59.5%, dyslipidemia 21.5% and diabetes 11.6%. Obesity, hypertension, and dyslipidemia were high in winter and WHR, diabetes and anemia were high in summer. Mean intakes of energy and nutrients were less than RI. Nutrients which were changed most by season were vitamin A and Vitamin C. Intakes of calcium and folic acid were less than recommended in summer. The ratio of CPF for carbohydrate was higher and fat was lower than recommended. In conclusion, the nutrient intake of Group 2 was better in quality but Group 1 was better in quantity. Nutrient intakes were poor in summer. In rural area, more careful nutritional assesment and management are needed for aged population, especially in summer.

This study was conducted to evaluate the rate of obesity of 212 women (age 45-60 years) in Seoul and the Kyunggi area through analysis of BMI and the dietary life factors related to obesity using a survey on dietary habits, dietary assessment, and nutrient intake. The height of the underweight group was taller than normal. The height of the obese group was equal to that of the normal group, but the weight was 8.5 kg greater than the normal group. Women in the underweight group consumed meals irregularly, and only 33.4% ate breakfast. Additionally, the rate of overeating was low in the underweight group, and milk, dairy products (yogurt, etc.), fruit, and fruit juice were consumed more than once a day. It was found that 62.1% of the women in the obese group never ate out, and the rate of eating one serving of fruit, drinking one cup of fruit juice, and eating various kinds of foods was high. The average point of women's dietary life was $21.9{\pm}2.9$, and 12.7% of all women responded that their dietary life was good. However, in the obese group, only 6.9% of the women reported that their dietary life was good. Evaluation of snacking habits revealed that the underweight group consumed a high level of carbonated drinks and ice cream, whereas for in the obese group, 24.1% of the women consumed milk and its products and 5.6% regularly consumed fast and fried foods. Evaluation of nutrient intake revealed that the consumption of energy, protein, vitamin A, vitamin $B_1$, $B_2$, $B_6$, niacin, vitamin C, and vitamin E was high in all of the groups, but the intake of folic acid in the underweight group was lower than the required level. Overall, 24.1% of the women in the obese group were found to have metabolic diseases, mostly hypertension (43%). In conclusion, a balanced diet to avoid excessive nutrient intake is needed to prevent obesity.

This study investigates general environmental factors influencing hypertension and diabetes patients and their disease control methods, self-efficacy, nutritional risk, diagnosis of eating styles according to nutritional risk, accountability in eating habit instructions, and nutritional intake and provides basic data for eating habit control in hypertension and diabetes patients. For this, 70 patients who visited a hypertension and diabetes admission center were interviewed using a questionnaire. According to the results, the implementation of self-efficacy in hypertension and diabetes was higher in female subjects. The diagnosis of eating type with nutritional risk was higher in female subjects, and there was a significant difference between male and female subjects (p<0.05). Both sexes had scores above 6 in nutritional risk and were diagnosed to have a "high-risk nutritional status." In the diagnosis of eating habits with nutritional risk, diet quality was higher for female patients (p<0.05), and the nutritional intake of subjects was low for most nutrients. In particular, the intake of calcium, vitamin A, riboflavin, and folic acid was low, indicating a need to improve eating habits for the balanced intake of nutrients because of the increasing importance of eating habits for controlling chronic diseases.

The purpose of this study was to investigate the eating patterns of children with cerebral palsy having motor disturbances as well as stiffness. The food habits, nutritional status, and snack intakes of 1 to 7 year-old children with cerebral palsy were examined. The subjects were grouped into three categories according to their table-utensil handling skills: superior, normal, and inferior. The children in the superior group were significantly taller and heavier compared to children in the other two groups. The %EARs of folic acid and total calorie intake were insufficient in all three groups; however, their %EARs of other nutrients were fully sufficient. When comparing the children's intake frequencies and preferences for snacks, the superior group showed a greater likelihood to consume various kinds of snacks than the inferior group. And the inferior group disliked more kinds of snacks than the other two groups. It was also shown that the inferior group had a significantly higher tendency for problems in chewing and swallowing. These results indicate that the development of table utensil-handling skills is very important for the food intake and growth of children with cerebral palsy, and the better their table utensil-handling skills the greater their physical development. Thus, considering their preference and intake frequency, it seems necessary that children in the inferior group be provided a greater variety of snacks and foods to receive more calories.
