The major purpose of this study was to develop the nutrition education contents and material through the basic data from the service provider and the consumer. And also, to find out the differences of attitude and needs between the service provider (SP breastfeeding specialist), present consumer (PC, pregnant or lactating women) and future consumer (FC, college women). There were types of questionnaires, which consisted of needs and attitudes toward child and maternal nutrition, as well as the personal characteristics of the study subjects. The subjects consisted of 113 breastfeeding specialists who served at medical related institutions, 197 pregnant or lactating women and 309 college women. The self-administered questionnaires from subjects were collected from October to November 2005 in Seoul and Kyunggi Province. The data was analysed by SPSS Win 12.0, ANOVA and Kruskal-Wallis test. The results of this study were as following: 1) The most Important determining factors on breastfeeding was 'medical specialist's support' (3.51) and the next one was 'knowledge of maternity care practice' (3.39). And the importance score of determinating factors on breastfeeding was significantly different between each group (p < 0.001). The groups of consumer (3.50 at PC and 3.59 at FC) considered the service provider (3.32) more important. The service providers considered a more effective determining factor to be 'husband and family support' and 'peer support' than the others (p <0.001). 2) To compare the effective factors of breastfeeding practices between the three groups, the service providers were more significantly considered than the otters such as 'attendance of intervention program' (p < 0.001). But the PC group considered the most effective factors wis 'mother's job after delivery'. 3) The self-evaluated score of the breastfeeding knowledge was the most high in SP; the score was significantly different between groups. The knowledge score of nutritional aspects in human milk was most highly evaluated. But maternity care practice and public acceptance marked the lower evaluation score than other issues. 4) The desirable types of educational material was mass media, and the next was printed matter such as booklets. Two kinds if consumers preferred DVD or VCR tapes than and the service provider group (p < 0.001). 5) The priority contents of nutrition service PC group wanted the information about infant care more than maternal care (p < 0.05), but FC group's priority was significantly different compared with PC group (p < 0.001). The priority of SP group pointed out the information of practical child care methods. The results showed the needs of nutrition service, education channels, and perception toward effective factors on consumer behavior changes were significantly different between each group. Thus the result of this study may suggest that consumer oriented nutrition service programs must be developed.

The longitudinal changes on human milk volume per day and lactational performance of Korean primiparae(n=9) and multiparae(n=6) from 0.5 month to 5 months after parturition have been studied by test-weighing method. The human milk volume per day tended to increase during lactation. The mean volume to the 3rd month of lactation was 643m1 for primiparae and 654m1 for multiparae, and it was 647 $\pm$ 182m1 for both of them. The mean volume to the 5th month of lactation was 648m1 for primiparae and 668m1 for multiparae, and it was 658$\pm$186$m\ell$ for both of them. The peak volume was observed at the 1st month of lactation in 8 women of 15 lactating women, that is, 53.3% . The high distributions of the individual mean volume to the 5th month were found 550~650$m\ell$(40.0% ) and 650~750$m\ell$(26.7% ). and 13 women of 15 lactating women(86.6% ) were observed below 750m1. The number of feeding per day was 7.7~9.3 to the 5th month and the mean volume per feeding was 65~101$m\ell$. While the former tended to decreased, the latter increased during lactation. The human milk volume was correlated with the peak volume. but not with maternal age. weight before delivery. maternal height and birth weight. As mentioned above, the human milk volume of Koreans was about 658$\pm$ 186$m\ell$ and 86.6% of it was below 750$m\ell$. So the human milk volume, referred to as 800$m\ell$ in recommended dietary allowances for Koreans might be estimated over real amount. It is necessary to study according to regions. socioeconomic levels. maternal nutritional status and the early stage of lactation.

The purpose of this study was to investigate how advanced maternal age influences lifestyle, nutrient intake, iron status, and pregnancy outcomes in pregnant women. The subjects of this study were 112 pregnant women who were receiving prenatal care at gynecologists located in Seoul. The subjects were divided into two groups according to their ages: those over age 35 were the advanced age group of pregnant women (AP) and those under age 35 were the young age group of pregnant women (YP). General factors, nutrient intakes, iron status, and pregnancy outcomes of the two groups were then compared. It was found that 72.5% of the YP group and 51.2% of the AP group had pre-pregnancy alcohol drinking experience; indicating that the YP group had more pre-pregnancy alcohol consumption than the AP group (P<0.05). The only difference found in nutrient intake between the two groups was their niacin intakes which were $16.83{\pm}8.20\;mg$/day and $13.76{\pm}5.28\;mg$/day, respectively. When gestational age was shorter than 38.7 weeks, the average infant birth weight was $2.95{\pm}0.08\;kg$, and when gestational age was longer than 40 weeks, it averaged at about $3.42{\pm}0.08\;kg$. In other words, as gestational age increased, infant birth weight increased (P<0.0001), and when maternal weight increased more than 15 kg, the infant birth weight increased significantly (P<0.05). In conclusion, in order to secure healthy human resources, with respect to advanced aged women, it is necessary to intervene by promoting daily habits that consist of strategic increases in folate and calcium intake along with appropriate amounts of exercise.

Background: This study aims to analyze West African pregnancy experienced women's self-rated health and related factors in Democratic Republic (DR) of the Congo, and provide basic data which can be used in developing maternal and child heath projects and health promotion programs to enhance women's self-rated health in the DR Congo. Methods: A survey was conducted among 400 women, 300 of whom were from Kenge and 100 from Boko in Bandundu Province. Three hundred and fifty-two questionnaires were administered on factors expected to affect the self-rated health, categorized into basic information and economic status of respondents, healthcare service, and illness patterns. The hierarchical logistic regression analysis was performed taking each variable into account. Results: The results show that those who have had nutrition education, work in the office, have no health insurance, or have had no illness for the last one year perceive themselves to be in good health. Conclusion: To improve the self-rated health status and promote maternal and child health in DR Congo, the results suggest that the government or relevant agencies should develop programs to educate people regarding health and nutrition, and policies based on the right status of each country. Systems are also required for healthcare at all social levels along with aspects to avoid illness in daily life.

The most abundant long-chain polyunsaturated fatty acid in brain lipids is docosahexaenoic acid(C22 : 6 N-3, DHA). It is incorporated into nerve tissues mostly in utero and during the first year of life. DHA in brain is derived from either pre-formed DHA in human milk or by infant hepatic synthesis from linolenic acid in milk. This study was designed to investigate the effects of DHA supplementation on fatty acid profiles in maternal plasma lipid and breast milk. Twenty lactating women participated in the study. Seven women took 3g of fish oil per day and vitamin E for 28 days starting from the day of giving birth. Five women consumed 1.5g of fish oil as well as tivamin E, and the rest took vitamin E supplements for the same period of time. Dietary questionnaires and 3 consecutive 24-h recalls were collected to evaluate theri nutritional status and food habits. Finding that DHA intake from fish was not significantly different among three experimental groups, the partcipants were instructed to continue eating their usual home diets. Milk samples were taken on the day of giving birth, as well as the 7th, 14th and 28th day being the supplement phase, and finally 2 weeks after the cessating of DHA supplements. The amounts of the fish oil supplements produced significant dose-dependent increased in the DHA content of milk and plasma, but to a lesser degree. Base-line for 28 days raised the level to 2.05$\pm$0.43% and 1.5g/day supplement produced DHA levels of 1.02$\pm$0.19%. The results of this study indicated that relatively small amount of dietary DHA supplementation significantly elevats DHA content in milk. This would clearly elevate the infant's DHA intake which in turn may have implications for the infant's brain development.

We examined the effect of parental folate deficiency on the folate content, global DNA methylation, folate receptor-alpha (FR${\alpha}$), insulin-like-growth factor-2 (IGF-2) and -1 receptor (IGF-1R) in the liver and plasma homocysteine in the postnatal rat. Male and female rats were randomly fed a folic acid-deficient (paternal folate-deficient, PD and maternal folate-deficient, MD), or folic acid-supplemented diet (paternal folate-supplemented, PS and maternal-folate-supplemented, MS) for four weeks. They were mated and grouped accordingly: $PS{\times}MS$, $PS{\times}MD$, $PD{\times}MS$, and $PD{\times}MD$. Pups were killed on day 21 of lactation. The hepatic folate content was markedly reduced in the $PD{\times}MD$ and $PS{\times}MD$ and $PD{\times}MS$ as compared with the $PS{\times}MS$ group. The hepatic global DNA methylation was decreased in the $PD{\times}MS$ and $PS{\times}MD$ groups as much as in the $PD{\times}MD$ group, and all the three groups were significantly lower as compared to the $PS{\times}MS$ group. There were no significant differences in the hepatic FR${\alpha}$, IGF-2 and IGF-1R expressions among the groups. Positive correlations were found between the hepatic folate content and global DNA methylation and protein expressions of FR${\alpha}$, IGF-2 and IGF-1R, whereas an inverse correlation was found between hepatic folate content and plasma homocysteine level in the 3-week-old rat pup. The results of this study show that both paternal and maternal folate deficiency at mating can influence the folate content and global DNA methylation in the postnatal rat liver.

Maternal nutritional status has been shown to influence pregnancy outcomes. And the elevated maternal plasma homocysteine concentrations have been associated with adverse pregnancy outcomes. We investigated the effects of maternal serum levels of B vitamins and homocysteine, and the C677T MTHFR (5, 10-methylenetetrahydrofolate reductase) polymorphism on pregnancy outcomes. In 177 pregnant women of 24-28 wks of gestation, the MTHFR gene mutation, serum B vitamins and homocysteine concentrations were measured, and their pregnancy outcomes were investigated from medical records. The birth length, and 1- and 5-min Apgar scores of neonates in the T/T mothers were 45.4 $\pm$ 9.3 cm, 7.6 $\pm$ 3.2 and 8.5 $\pm$ 3.8, respectively, which were significantly lower than those in the C/T (48.6 $\pm$ 3.3 cm, 9.0 $\pm$ 0.2, 10.0 $\pm$ 0.2) or the C/C mothers (49.4 $\pm$ 1.9 cm, 9.0 $\pm$ 0.2, 10.0 $\pm$ 0.0). The birth weight, birth length and the gestational age of neonates at delivery from hyperhomocysteinemic mothers whose homocysteine levels higher than 15 $\mu$ mol were 2.5 $\pm$ 1.3 kg, 43.9 $\pm$ 9.0 cm, 35.4 $\pm$ 6.3 wk, respectively, which were significant lower than those from normohomocysteinemic mothers (3.1 $\pm$ 0.6 kg, 48.8 $\pm$ 3.6 cm, 38.5 $\pm$ 2.5 wk). The birth weight and birth length of neonates in mothers whose PLP levels were below the median were significantly lower than those from mothers with the PLP levels above the median. The 1- and 5-min Apgar scores of neonates were lower in mothers with the T/T MTHFR genotype than those with the C/T or C/C only when the serum PLP levels were below the median. The 1-, 5 min Apgar scores and birth length of neonates were lower in mothers with the T/T MTHFR genotype than those with the C/T or C/C only when the serum FMN levels were below the median. In conclusion, maternal B vitamin status, homocysteine and the C677T MTHFR genotype seem to have played an important role on pregnancy outcomes.

The longitudinal changes on human milk volume per day and lactational performance of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) from 0.5 to 5 months after parturition have been studied by test weighing method. The human milk volume per day tended to increase during lactation. The mean volume (SD, ml/day) at 0.5, 1, 2, 3, 4, 5 months were 502(102), 692(127), 697(100), 684( 125), 757(52), 703(70), respectively. The overall mean volume was 661$\pm$132ml/day. The peak milk volume during the lactation was observed at most lactating women at the 1st month. The distributions of the individual mean volume during the first 5 months of lactation were found over 750m1(8.7% ), 650-750ml(47.9% ), 550-650m1(2l.7% ), and 450-550ml(2l.7% ) The number of feeding per day was 8.1 ($\pm$1.0) at 0.5 months postpartum, which was consistently decreased. However, the mean volume per feeding was increased from 62($\pm$9.5)ml at 0.5 month to 112($\pm$13.3)ml at 5 months postpartum. The milk volume was correlated with the peak volume. and maternal age. but not with weight before delivery. maternal height and birth weight. No differences of milk volume and lactational performance between facto-ovo-vegetarian and nonvegetarian women were observed. This study suggests that the human milk volume cited in the recommended dietary allowances for Koreitns is over estimated.

The purpose of this study was to investigate the effects of regular maternal exercise on maternal nutrients intake and pregnancy outcome. The number of subjects were 567 pregnant women at local general hospital in Daegu. General characteristics data and 24- hour food recalls were collected by trained interviewer. Structured interview and medical record review were carried out at first prenatal and delivery visit(included age, delivery history, height, pre-pregnancy weight, and pregnancy outcome etc). Regular exercise performance was surveyed at third trimester and 31.4% of subjects exercised regularly Overall weight gains during pregnancy were 13.9 $\pm$ 3.8kg and 14.7 $\pm$ 4.7kg in the exercise and sedentary group, respectively. The type of exercise was mainly strolling and light aerobic exercise. Usually firstpara subjects exercised more regularly than multipara subjects. There is no significant difference between regular exercise and severity of morning sickness. Weight gain during pregnancy was not relate to regular exercise. Though there is not statistically significant, the nutrients intakes were higher in regular exercise group than in sedentary group. We concluded regular exercise during pregnancy neither influenced pregnancy weight gain, severity of morning sickness nor baby birth weight but it could affect the nutritional and health statues of mother.

The process of breast feeding was investigated from the 36th week of pregnancy to 12 weeks postnatal, in order to analyze the factors affecting breast feeding duration and provide the basic data on an education program for successful breast feeding. The general characteristics of study group had no marked effects on the breastfeeding duration. The young and highly condition during pregnancy and the degree of morning sickness affected the practice of breastfeeding. In the study of prenatal sociobehavioral factors, intended duration affected the breastfeeding duration, and the maternal perception that breastfeeding is good for weight loss after delivery as well as infant formula milk is not as good as breast milk, led to successful breast feeding. Among the postnatal biological factors, the duration of gestation affected the breast feeding. Among the postnatal biological factors, the duration of gestation affected the breastiffeding outcome. In the case of early parturition, breastfeeding rate was low. Among the postnatal biocultural factors, time of first feed, milk volume and maternal perception of infant's sucking ability affected the bresatfeeding duration. From these result, it is suggested that an education program such as participation of nursing class to the pregnant women should be provided for successful breastfeeding.
