This study aimed at investigating correlation of nutrients intake and serum lipids of industrial workers. 226 for adult aged 20yr~59yr (average age 35.9yr) were selected as subjects during 6 months, from June to December, 1997. Nutrients intake was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows ; In total subjects, calories, calcium, vitamin A, vitamin $B_1$, and vitamin $B_2$ were below Korean RDA(recommended dietary allowances) and protein, iron, vitamin C, niacin and phosphorus were above Korean RDA. Distribution of BMI groups were underweight groups(7.9%), normalweight groups(63.3%) and overweight groups(28.8%). In BMI groups, intakes of calories, carbohydrates, protein, fats, iron, niacin and potassium of overweight groups were higher than those of other groups, significantly(P<0.001). Intakes of calcium of underweight groups were lower than those of other groups, significantly(P<0.05). BMI increased with age. Total cholesterol, triglyceride, apo(b) and atherogenic index of overweight groups were higher than those of other groups, significantly(P<0.001). Calories, carbohydrates, protein, fats, iron, vitamin $B_1$, vitamin $B_2$, niacin, natrium and potassium were positively correlated with BMI, significantly(P<0.001). Calcium and vitamin C were positively correlated with BMI, significantly(P<0.01). vitamin A and phosphorus were positively correlated with BMI, significantly(P<0.05). Total lipid, total-chol., triglyceride, apo(b) and atherogenic index were positively correlated with BMI, significantly(P<0.001). HDL-chol. were negatively correlated with BMI, significantly(P<0.001). Above results, the more BMI and age increased, the worse patterns of serum lipid, so that increased atherogenic index that increased risk of atherosclerosis and degenerative chronic disease connected with serum lipid. After classified by BMI, age and lipid pattern, it will be managed individually for health management of industrial workers. Development and application of efficient program will be urgent for harmonious nutrition counseling and guidance.

The purpose of this study was to investigate and examine the relationship between dietary habits, food intake patterns, and depression in Korean women with polycystic ovary syndrome (PCOS). The Center for Epidemiologic Studies Depression Scale Korean Version was used to determine whether a participant was depressed or not. The dietary habits were assessed by the Min-Dietary Assessment (MDA) method, and food intake data were collected by the 24-hour recall method on two non-consecutive days, at least 7 days apart, and the average of the two days was used to estimate the usual dietary intake. The total MDA scores of the Depression Group was significantly lower than that of the No-Depression Group ($31.5{\pm}6.4$ vs $33.4{\pm}6.0$, p = 0.027). The intake of cereals/potatoes/sugar products, milk and milk products, plant protein, and calcium for the Depression Group were significantly lower compared to the No-Depression Group. The Depression Group had a significantly higher percentage of energy intakes from protein as well as the consumption of fish and shellfish compared to the No-Depression Group. There was a significant inverse relationship between milk and milk products consumption and the prevalence of depression [OR (95% CI) for the highest tertile compared to the lowest: 0.390 (0.177-0.857); p for trend = 0.016]. There were also significant positive relationships between the prevalence of depression and the consumption of the following: fish and shellfish [OR (95% CI) for the highest tertile compared to the lowest: 2.319 (1.128-4.770); p for trend = 0.009], animal protein (p for trend = 0.049), and the percentage of energy intakes from protein [OR (95% CI) for the highest tertile compared with the lowest: 2.546(1.156-5.609); p for trend = 0.025]. Further studies are needed in order to investigate whether the intake of protein and of animal protein is indeed associated with depression in PCOS patients in Korea and the possible mechanisms thereof. The results of our study can be applicable for the development of effective nutrition counseling and education programs regarding PCOS patients with depression as part of their successful treatment regimen.

This study was conducted to investigate actual conditions and needs on breastfeeding education for pregnant women in health centers for the development of a breastfeeding educational program. The questionnaires were mailed to 245 health centers and 148 (60.4%) questionnaires were returned. 91% of the health centers had breastfeeding education for pregnant women. 66% of them operated breastfeeding education as one part of other health programs. About 76% of supervisors and 64% of educators were the nurses. The teaching methods frequently used were lectures (30.5%), giving out booklets and leaflets (22.6%), demonstration and practice (21.5%), personal counseling (13.3%), and others. The teaching materials used were materials of outside speakers (39.7%), materials of development oneself (19.0%), materials of academic association or institute (14.8%), and others. The subjects which educators taught were the benefits of breastfeeding (16.7%), breastfeeding techniques (15.8%), caring for breasts before and after delivery (15.1%), nutritional management for lactating women (14.2%), coping strategies for the difficult situation of breastfeeding (13.3%), and others. Those were different from each other according to the educators' general characteristics. Success factors of education were increased motivation for breastfeeding (52.8%), practice (22.6%), professional's lecture (11.3%) and others. The failure factors of education were the ineffectiveness of the lecture method (69.2%), lack of education for supporters (15.4%) and lack of standardized education (15.4%). The most important barrier of education was the lack of a standardized breastfeeding educational programs (43.9%). The most effective teaching methods that educators thought were demonstration and practice (24.0%). The educators thought they need the tools and space for practice (28.2%), a standardized breastfeeding educational program (26.9%), and the human resources (24.4%) for effective education. Subjects that educators thought important for education were the breastfeeding techniques, benefits of breastfeeding, caring for breasts before and after delivery, nutritional management for lactating women, coping strategies for the difficult situation of breastfeeding, rooming system after delivery, ways to assess mother's milk quantity, introducing successful cases of breastfeeding in rank order. To promote the effectiveness of breastfeeding education, standardized breastfeeding educational programs, diverse teaching materials, space and tools, and human resources are needed.

Purpose: The aim of this study was to investigate the feeding patterns, use of dietary supplements, and nutrient intake of Korean toddlers. Methods: We used data for 930 toddlers who participated in the 4th Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2009. Feeding patterns and use of dietary supplements were assessed using standardized questionnaires, and nutrition intake was assessed using the 24 hr recall method. Results: In 2007~2009, 48.7% of toddlers used dietary supplements. Most parents (95.4%) initiated a regime of dietary supplements for their children following the advice of friends or relatives. Only 0.4% of parents followed the advice given by their doctors for dietary supplements use. In the survey of nutrient intake for toddlers, the prevalence of inadequate calcium intake was 53.9% for subjects aged 1 year, 55.2% for 2 years and 65.6% for subjects aged 3 years. The prevalence of inadequate iron intake was 52.0% for subjects aged 1 year, 48.7% for 2 years and 48.4% for subjects aged 3 years. In the survey performed on feeding patterns of toddlers during the infant period, mixed feeding accounted for 57.4%, breast feeding for 32.2%,and formula feeding for 10.4%. Sixty-five percent of toddlers began weaning between 4 and 6 months. Conclusions: This study indicated that a number of toddlers were at risk of inadequate calcium and iron intake. The role of professionals in counseling for qualified dietary intake and dietary supplement use is therefore necessary for Korean toddlers.

Purpose : Through a survey undertaken among doctors practicing pediatric patients in primary medical facilities on nutrition during infancy, the present study was done to determine whether these doctors were giving appropriate advice on infant nutrition. Methods : We visited pediatric specialists(group one) and non-pediatric specialists or general practitioners(group two) who were practicing in Daegu to ask them to fill out a questionaire on infant nutrition. Results : When 10 points were given to each question for a total of 100 points, the results of the evaluation showed that the score in group one was $73.0{\pm}15.8$ points and $45.1{\pm}18.4$ points in group two, showing a significant difference. No statistical difference was seen in the scores between non-pediatric specialists and general practitioners. Each answer to each question on the feeding period of breast milk, on loose stools during breast milk feeding, methods to deal with jaundice during breast milk feeding, choice of commercial baby food, criteria on directing soy milk, and criteria of guiding infant cereal was different between group one and two. Conclusion : The results of the present investigation showed that specialists in other fields or general practitioners were giving inappropriate advice on nutrition during the infant stage compared with pediatric specialists; thus, we need to confirm methods to prevent inappropriate consultations by specialists of other fields, together with continued education of pediatric specialists.

This study examined consumer perception and use on labeling of cooking utensils made of plastic and glass to get information about improving the labeling. The data were collected from 505 adults in Seoul, Busan, Daegu, Daejeon, Incheon, and Gwangju. The data were analyzed by SPSS Windows V.14.0. Frequencies, t tests, one-way analysis of variance, and Duncan's multiple range tests were carried out. Many respondents checked off 'precautions in use' more than any other notice when they purchased the cooking utensils made of plastic and glass. Respondents were dissatisfied with the letter size and intelligibility of foreign language on the labeling. Most respondents preferred 'tag' for most cooking utensils made of plastic and glass. In addition, on necessity of precautions for each category of plastic cooking utensils, frying pans, plastic baskets, plastic water buckets, plastic seasoning bottles, the frying pan showed the highest need for 'do not place close to the fire'. Plastic cups and plastic containers showed the highest in 'whether utensils could be used in the microwave oven and accompanying precautions', and plastic cutting board showed the highest in 'matters relating to washing before use.' In the case of cooking utensils made of glass, 'precaution on shock' was the highest for glass cups and mugs and 'whether utensils could be used in the microwave oven and accompanying precautions' was the highest for glass pans, dishes and containers.
