Essential fatty acids are important essential nutrients during pregnancy. The objective of this study was to compare fatty acid composition of serum phospholipids and essential fatty acid intakes between Korean pregnant women with a single baby and Korean pregnant women with twins. A total of 116 pregnant women who had maintained their health without any symptoms of pregnancy complications participated in the study. The subjects consisted of 57 women of singleton pregnancy and 58 women of twin pregnancy at the 1st, 2nd, or 3rd trimester of pregnancy. A 24-hour dietary recall was administered to each subject to obtain dietary information. The mean ages of the singleton pregnancy group and the twin pregnancy group were 31.44 years and 32.27 years, respectively, and the mean height values were 161.86 cm and 160.64 cm, respectively. The mean daily energy intakes in the singleton pregnancy group were 1639.95 kcal, 1904.71 kcal, and 1882.82 kcal for the 1st, 2nd, and 3rd trimester group, respectively. The mean daily energy intakes in the twin pregnancy group were 1745.99 kcal, 2203.46 kcal, and 2092.26 kcal for the 1st, 2nd, and 3rd trimester group, respectively. There were no significant differences in the mean fatty acid intakes by the type of pregnancy (i.e., singleton vs. twins) and the stage of pregnancy (i.e., 1st vs. 2nd vs. 3rd trimester). However, the mean total fatty acid intake of those at the 1st trimester among the singleton pregnancy group tended to be higher than that of those at the 1st trimester among the twin pregnancy group. Such a trend seemed to be retro-versed. That is, the mean total fatty acid intakes of the twin pregnancy group were higher compared to the singleton pregnancy group for the 2nd and 3rd trimester group. The LA and total n6 concentrations of serum phospholipids of the singleton pregnancy group were significantly higher as the gestational age increased(p<0.05). The $\alpha-LNA$(p<0.05), EPA(p<0.05), and total n3(p<0.001) concentrations of serum phospholipids of the twin pregnancy group were significantly lower as the gestational age increased. The $\alpha-LNA$ concentrations of serum phospholipids in the singleton pregnancy group at the 3rd trimester were significantly higher than that in the twin pregnancy group at the same trimester(p<0.05). The serum phospholipids levels of AA and DHA of the twin pregnancy group were generally higher compared to those of the singleton pregnancy group. Particularly the differences reached at the level of statistical significance for those at the 1st trimester(p<0.01). It is concluded that the study findings imply that fatty acid metabolism may meaningfully differ by the type and stage of pregnancy. Future research needs to be conducted to more elucidate grounding etiology and possible roles of dietary fatty acid intake levels in relation to the study findings.
The necessity of school health promoting projects is well known to many researchers, however, there is a lack of research on the development of strategies for school health programs and the evaluation of the effectiveness of the programs. The results of our previous study in 1996 identified poor eyesight as one of the several health problems among elementary school children in urban areas. The main objective of this study is to develop, implement, and evaluate vision care for elementary school children. The research method utilized a quasi experimental design using non-equivalent group, pre-post comparison. The sample consisted of all second grade children in two elementary schools in Kyung-giProvince. In order to prevent a contamination effect of the vision care program, one school was selected as a control and the other school was selected as a treatment group. The experimental school had 467 children and the control school had 402 children. The visual acuity of children in both group was measured and a survey questionnaire was sent out to parents on the knowledge, attitude, and behavior related to vision care before the program was implemented. The children of the experimental school received the following programs; separate education on proper nutrition and care of eyesight for children and parents, daily eye exercises using video tape, and an essay and poster contest on healthy eyesight. The eye exercise program lasted from March, 1997 to November, 1997. On November, 1997, visual acuity was measured again from children in both schools. The data was analyzed by using SAS statistical package. The results indicate that the children in the experimental group had significantly (p〈0.001) better eyesight than the children in the control group. Also, some of the behavior highly related to the poor eyesight are poor maternal eyesight and watching TV from a short distance. In conclusion, one of the significance of this project is that the vision care program was developed after the need assessment. It will be encouraged in the future that more school health program should be developed after a need assessment. Also, inclusion of family members was important in health promoting projects within a school setting since healthy behavior needs to be reinforced at horne as well as at school.

Reproduction in ruminant species is a highly complex biological process requiring a dialogue between the developing conceptus (embryo-fetus and associated placental membranes) and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling and regulation of gene expression by uterine epithelial and stromal cells. The uterus provide a microenvironment in which molecules secreted by uterine epithelia and transported into the uterine lumen represent histotroph, also known as the secretome, that are required for growth and development of the conceptus and receptivity of the uterus to implantation by the elongating conceptus. Pregnancy recognition signaling as related to sustaining the functional lifespan of the corpora lutea, is required to sustain the functional life-span of corpora lutea for production of progesterone which is essential for uterine functions supportive of implantation and placentation required for successful outcomes of pregnancy. It is within the peri-implantation period that most embryonic deaths occur in ruminants due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. The endocrine status of the pregnant ruminant and her nutritional status are critical for successful establishment and maintenance of pregnancy. The challenge is to understand the complexity of key mechanisms that are characteristic of successful reproduction in humans and animals and to use that knowledge to enhance fertility and reproductive health of ruminant species in livestock enterprises.

The purpose of this study was to evaluate the nutritional knowledge and dietary behaviors of middle school students according to their mother's employment status. Of all 453 subjects, 52.1% were boys, and 67.5% of the mothers were employed. The total score of nutritional knowledge was 8.0 out of 10 for students with a non-working mom and 7.7 for those with a working mom, showing no significant difference. Among the 20 nutritional knowledge questions, correct answer rates for "lots of fruits may be eaten because of not gaining weight" (72.6% vs. 81.6%, p<0.05) and "eating raw carrots is better than eating fried ones with oil" (34.6% vs. 44.9%, p<0.05) were significantly higher in students with a working mom. The regularity of meals showed a significant difference according to the mother's employment, indicating that responses of "very regular" (62.4% vs. 72.1%) were high among students with a non-working mom and responses of "skipping breakfast" (31.4% vs. 19.7%) were higher in students with a working mom (p<0.05). The number of snacks a day was also significantly different according to the mother's employment, showing that 12.8% of the students with a working mom and only 3.4% of them with a non-working mom did not eat snacks at all (p<0.05). These results reveal no significant difference in middle school students' nutritional knowledge according to their mother's employment status; however, the students whose mother had a job were more likely to have more undesirable dietary behaviors such as irregular meals and snacking.
Objectives: Poor complementary feeding practices have consistently contributed to the burden of child undernutrition in Indonesia. This study aimed to estimate the prevalence and predictors of the time of the introduction of solid, semi-solid, and soft foods (ISSSF), minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD). Methods: We analyzed 4804 last-born infants aged 6-23 months from the 2017 Indonesia Demographic and Health Survey, which employed multistage cluster random sampling. The outcomes were calculated based on the 2021 World Health Organization/United Nations Children's Fund guidelines. The predictors of the 4 complementary feeding indicators were assessed using multivariate Poisson regression with robust variance adjusting for potential confounders and study design. Results: The prevalence of ISSSF, MDD, MMF, and MAD was 86.1%, 54.3%, 71.8%, and 37.6%, respectively, with younger children less likely to meet 3 out of the 4 outcomes. Parental education, the presence of a birth attendant, and maternal media consumption were among the predictors of MDD and MAD. Children from families with higher income were more likely to meet MDD than those from low-income households (adjusted prevalence ratio [aPR], 1.16; 95% confidence interval [CI], 1.05 to 1.28). Living in an urban area was positively associated with MMF (aPR, 1.09; 95% CI, 1.04 to 1.15) and MAD (aPR, 1.12; 95% CI 1.02 to 1.24). In eastern regions, the prevalence of children achieving MDD and MAD was lower than in those living in Java and Bali. Conclusions: It is crucial that more attention and efforts are made to improve the recommended practices throughout Indonesia, since the prevalence of adequate complementary feeding practices remains low.
This study is a descriptive research study with secondary analysis of data from the 8th National Health and Nutrition Examination Survey. The purpose of this study was to analyze the prevalence and awareness of diabetes in 300 Korean adults aged 30 to 49 with diabetes, and to identify the factors influencing it. For data analysis, the composite sample frequency and percentage, χ2-test, and logistic regression analysis were performed using the SPSS 25.0 program. Among the diabetic patients, 171 patients (57.0%) recognized that they had diabetes, and the factors influencing cognition were gender, education level, BMI, subjective health status, cardiovascular disease, and paternal and maternal family history. Based on the results of this study, it can be used as basic data to establish policies and intervention programs that reduce the prevalence of diabetes in relatively young people aged 30 to 49 years and increase awareness among those with diabetes in Korea.
To determine the relationships between soybean food intake, dietary isoflavone intake, and osteoporosis incidence, questionnaire surveys, bone mineral density measurements, and dietary surveys by food record were performed with 19 postmenopausal women ($57.6{\pm}7.3$ yrs of age) in Daejeon city. The subjects were divided into two groups: an 'osteoporosis group' (OG, n=10) and a 'normal group' (NG, n=9). Mean age, height, and body weight were similar between the two groups but BMI was higher in OG than in NG. Mean age at menarche was not different between the two groups. However, mean number of childbirths was greater in OG than in NG and mean total period of lactation was shorter in OG. Mean exercise time per week was similar between the two groups, and mean time of sunlight exposure tended to be shorter in OG. Mean daily intake of calcium was lower in OG whereas sodium intake was higher in OG. Mean daily intakes of total soybean food (OG: $203.8{\pm}84.6\;g/d$, NG: $285.0{\pm}146.3\;g/d$) and total dietary isoflavone (OG: $29.1{\pm}14.3\;mg/d$, NG: $38.3{\pm}23.1\;mg/d$) were not different between the two groups. However, greater intakes of soybean food and dietary isoflavone were associated with higher bone mineral density, respectively. The above results indicate that osteoporosis incidence tends to be influenced by BMI, maternal factors, dietary nutrient intakes, soybean food intakes, and dietary isoflavone intakes in postmenopausal women; although no significant differences in soybean food and dietary isoflavone intake were found between the two groups. This tendency implies that greater intakes of soybean food and dietary isoflavone lead to lower incidence of osteoporosis in postmenopausal women.
Background: Parental attention is crucial for preventing childhood oral diseases. Mothers play a significant role in maintaining their families' oral health, and their educational level influences their children's oral health behaviors. This study investigates the impact of mothers' educational levels on adult oral health behaviors using data from a national survey. Methods: This study employed a cross-sectional analysis of secondary data. The data used were obtained from the 8th Korea National Health and Nutrition Examination Survey. Descriptive statistics were calculated to identify participant characteristics. Next, t-tests and one-way analysis of variance were conducted to examine the effects of the explanatory variables on the distribution of the dependent variable. Finally, logistic regression analysis was used to investigate the influence of the explanatory variable on the dependent variable, using "no education" as the reference value, and calculate the odds ratios. Results: Children of mothers with a college education or higher had a 1.13 times higher likelihood of receiving oral examinations than those whose mothers had no education. Children whose mothers graduated from college or higher had a 2.23 times higher probability of receiving preventative dental treatment than those whose mothers had no education. Children whose mothers graduated from college or higher had a 1.92 times higher probability of receiving scaling than those whose mothers had no education. Children whose mothers graduated from high school had a 1.35 times higher probability of receiving scaling than those whose mothers had no education. Conclusion: Developing oral health programs is important for low-educated and low-income parents to change theirs and their children's oral health behaviors/attitudes. This will help reduce oral health disparities among adults raised by parents of higher and lower socioeconomic statuses. Therefore, a comprehensive approach is essential for adults to maintain good oral health, regardless of variations in their parental educational levels during childhood.
The influence of stage of lactation on the moisture. total soilds, ash, calcium, phosphorus and Ca/P ratio of human milk was studied. A total number of 32 lactating mothers provided 101 samples collected at 4 consecutive stages of lactation : days o to 5 postpartum(colostrum); days 6 to 10 postpartum(transitional): days 25-35 postpartum(mature). and days 55-70 postpartum(mature). Moisture and total solids concentrations showed a little but significant difference at the 25-35 day stage as compared with those of colostrum and then remained stable, but ash levels decreased significantly with the elapse of lactation period. Calcium levels increased significantly from colostrum to transitional milk stage with a further less significant increase at mature stages. Between colostrum and transitional stages, phosphorus concentration showed a significant increase $(9.9\pm2.4$ vs $15.5\pm4.9$ mg/100 ml, p<0.001)but between the 25-35 day and the 55-70 day stage phosphorus values did not change significantly. Ca/P ratios for colostrum. transitional, the 25-35 day and the 55-70 day stages were 2.28, 1.76, 1.68 and 1.95, respectively. No significant relationship was found between ash. calcium, phosphorus or Ca/P ratio of milk and maternal parity. When modified milk formulas were reconstituted using the total solids of human mature milk as amount of the modified milk formula in 100 ml of infant feeding solution. ash, and Ca/P ratio were similar to those of human milk. However considerably higher concentrations of calcium and phosphorus exist in the reconstitution fluid than those observed in human milk.
Purpose: The prevalence of childhood obesity has increased dramatically. It is important to know about life style and dietary habits of the obese children because the treatment of childhood obesity focuses on using behavioral modification techniques. We aimed to develop a questionnaire for the purpose of providing convenient and useful guidance to pediatricians who evaluate and treat obese children. Methods: Previously developed questionnaire was given to 94 obese children and their parents who had visited clinic for obese children and adolescents. We analyzed response rates on questions and reliability between children and their parents. Results: The response rates on questions were somewhat high. Agreement of paired questions of both parents and children was also moderately high (63~92%). It is acceptable to complete questions by either parents or children alone. Items for hours of playing video games or computer, maternal job, kind of consuming beverage and food outside home were added. Conclusion: We concluded that some questions are not needed to be given to both parents and their children. It would be better to have parents record life style of their children and to have children record their food intake with physical activity outside home.
